The main goals of the project are: 1/ minimize the security model of FAM 2/ simplify the code base 3/ provide an API and ABI compatible replacement for FAM 4/ try to fix some other issues like resource consumption The project home page is (temporary) at: http://www.gnome.org/~veillard/gamin/ A mailing list is also available to discuss about this project, see the following URL for subscription informations: http://mail.gnome.org/mailman/listinfo/gamin-list and the on-line archives: http://mail.gnome.org/archives/gamin-list/ The CVS base is in the GNOME project CVS base at cvs.gnome.org, the module name is 'gamin'. See http://developer.gnome.org/tools/cvs.html From an historical point of view, gamin builds from the marmot project authored by James Willcox and Corey Bowers and then heavilly modified to turn it into a minimalist FAM replacement (Francophones will appreciate the filiation from fam to marmot and gamin) This library is available under the terms of the GNU LIBRARY GENERAL PUBLIC LICENSE, and a copy of it should be found in the source under the COPYING file.

If kqueue cannot monitor a file, this backend * will poll it periodically. * * * Monitoring a file with kqueue prevents the file system it * resides on from being unmounted, because kqueue can only * monitor open files. * * * The creation of missing monitored files is detected by * performing a lstat() every second. Although using kqueue to * monitor the parent directory is technically feasible, it * would introduce a lot of complexity in the code. * * * In light of the previous points, it appears that: * * - kqueue needs to be augmented with a filename-based * monitoring facility; * * - kqueue needs to be moved out the UFS code. * * Copyright (C) 2005 Joe Marcus Clarke * Copyright (C) 2005 Jean-Yves Lefort * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public * License as published by the Free Software Foundation; either * version 2 of the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

These restrictions translate to certain responsibilities for you if you distribute copies of the library, or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link a program with the library, you must provide complete object files to the recipients so that they can relink them with the library, after making changes to the library and recompiling it. And you must show them these terms so they know their rights. Our method of protecting your rights has two steps: (1) copyright the library, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the library. Also, for each distributor's protection, we want to make certain that everyone understands that there is no warranty for this free library. If the library is modified by someone else and passed on, we want its recipients to know that what they have is not the original version, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that companies distributing free software will individually obtain patent licenses, thus in effect transforming the program into proprietary software. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License, which was designed for utility programs. This license, the GNU Library General Public License, applies to certain designated libraries. This license is quite different from the ordinary one; be sure to read it in full, and don't assume that anything in it is the same as in the ordinary license. The reason we have a separate public license for some libraries is that they blur the distinction we usually make between modifying or adding to a program and simply using it. Linking a program with a library, without changing the library, is in some sense simply using the library, and is analogous to running a utility program or application program. However, in a textual and legal sense, the linked executable is a combined work, a derivative of the original library, and the ordinary General Public License treats it as such. Because of this blurred distinction, using the ordinary General Public License for libraries did not effectively promote software sharing, because most developers did not use the libraries. We concluded that weaker conditions might promote sharing better. However, unrestricted linking of non-free programs would deprive the users of those programs of all benefit from the free status of the libraries themselves. This Library General Public License is intended to permit developers of non-free programs to use free libraries, while preserving your freedom as a user of such programs to change the free libraries that are incorporated in them. (We have not seen how to achieve this as regards changes in header files, but we have achieved it as regards changes in the actual functions of the Library.) The hope is that this will lead to faster development of free libraries. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, while the latter only works together with the library. Note that it is possible for a library to be covered by the ordinary General Public License rather than by this special one. GNU LIBRARY GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Library General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also compile or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. c) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. d) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Library General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Gamin is a file and directory monitoring system defined to be a subset of the FAM (File Alteration Monitor) system.

reformatting of comments in gtk-doc style - handling of directory removal (need to poll on monitored empty dirs). - check handling of mismatched resources i.e. mondir on file and monfile on directories and what happen when file type change. - mount --bind will certainly create infinitely deep directory trees surely you are doing loop detection for this, for NFS and the like ? (Alan) - on SIGUSR2 first output the list of clients connected and try to force the glib2 main loop to output the informations at the time the event are received. - try to work around the fact the stat() info precision is only 1 sec on ext2/ext3, especially for directories. - avoid deadlock on reconnect due to event piling up in both directions. probably need a protocol upgrade. - handling of symlinks with dnotify. Regression tests: - try all the file length on the client till error. - try the fragmented/multirequests tests on the client side Postponed: - "make valgrind" regression tests for both client and server. -> valgrind doesn't work okay with dnotify Done: - fix "make tests" to use /tmp to avoid $pwd in the paths of the output - automatic switch from dnotify to poll for resources generating too much kernel events. - handling of missing monitored resources where dnotify() won't work - DV, gam_server should prolly be in /usr/libexec - path flexibility for the remote server in gam_fork.c (needed for make tests) - code merge between client and server, e.g. libgamin/gam_error.[ch] and server/gam_error.[ch] ? - test for availability of setsid(), usleep() - code and file cleanup, indenting - removed old common dependancy - autostart/stop of the server side - cleanup deps w.r.t. libmarmot - add a flag for server to not exit on idle: --notimeout - block exports of all symbols not from fam.h : done for the shared library the static one still exports gamin_* symbols though - code 'cb' processing cleanup - make Copyright file for LGPL - check both ways of identification, not just server checking client. - on the client handle numbers provided by the caller. - removed threading and locking, checked with snorp that's not really needed now that there is no DBus plug nor recursion, still use a pipe to handle event synchronously. - restart the connection and monitor on the client side if the server exits - special case where dnotify is not a good idea (temporary storage) gamin-0.1.10/missing0000775014173200001050000002540610642721161011213 00000000000000#! /bin/sh # Common stub for a few missing GNU programs while installing. scriptversion=2005-06-08.21 # Copyright (C) 1996, 1997, 1999, 2000, 2002, 2003, 2004, 2005 # Free Software Foundation, Inc. # Originally by Fran,cois Pinard , 1996. # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2, or (at your option) # any later version. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

gamin uses a client server model, this is in a large measure justified by the inappropriate dnotify kernel API way to signal modification events to an application but also to share kernel signal when multiple application monitors the same resource. It also allow to fine tune and filters event flow in the daemon, potentially minimizing resource consumption in applications.

One server and two client connected

Internally the gam_server maintain various data structures:

  • A tree of monitored nodes, using both GamNode structure containing specific informations (like the path, the subscriptions list for that node, monitoring data and whether it's a directory), the tree itself is based on a GNode N-ary tree.
  • Per connection data (GamConnData) one per connected socket. The data includes state, connection informations (file descriptor, Glib I/O Channel, pid of the application), and potential unprocessed yet data request from the socket.
  • Listener information, keeps the list of subscriptions for the connected application, this could probably be merged in the connection data.
  • For each path monitored by an application, a specific GamSubscription structure is maintained. The subscriptions are referenced both from the monitored nodes tree and from the listeners.

the data structures present in the server

Basically it is exactly like for using the fam interface. From a programmer point of view this is the same API, and one can make use of the existing FAM documentation.

While gamin still use a server to provide the service (ideally if the kernel had a proper interface a library only implementation should be doable and possibly better), it tries to avoid security hazard associated to contacting an external server process:

  • the server runs under the same privilege level as the client, by running under the uid, no root or superuser access is involved, this is checked by both side using kernel support for the checking
  • when possible (e.g. on Linux) the socket used to communicate is not mapped at the filesystem level to avoid risks related to opening a real file, if the kernel doesn't allow this a per user directory holding the socket is used and appropriate rights are checked.
  • to limit DoS attacks done by continuously modifying a monitored resource, the daemon will switch back monitoring of very busy resources to polling with generation of events only once per second.

Here is the process used to acquire and create the sockets:

If there is abstract socket support:

Use the filename "\0/tmp/fam-$USER-$GAM_CLIENT_ID". They are not mapped on the filesystem, no attack is possible that way. The client and the server checks on the first '\0' byte received from the socket that the other side is running under the same UID.

If there is no abstract socket support:

On the server side:

 start:
  try to create /tmp/fam-$USER using mkdir('/tmp/fam-$USER', 007)
  if error:
      make a stat() on it
      if doesn't exist:
          return failure to create
      if user is not getuid() or mode is not 007 or type is not dir:
          try to unlink()
          if error:
              exit with error.
          if success:
              goto start:
                                                                                
  do the socket()/bind() on /tmp/fam-$USER/fam-$GAM_CLIENT_ID

On the client side:

  make a stat on /tmp/fam-$USER
  if doesn't exist:
      return failure to create should start the server
  if user is not getuid() or mode is not 007 or type is not dir:
      try to unlink()
      if error:
          exit with error.
      if success:
          return failure should start the server
  make a stat on /tmp/fam-$USER/fam-$GAM_CLIENT_ID
  if doesn't exist:
      return failure to create should start the server
  if user is not getuid() or type is not socket:
      try to unlink()
      if error:
          exit with error.
      if success:
          return failure should start the server
                                                                                
  do the socket()/connect() on /tmp/fam-$USER/fam-$GAM_CLIENT_ID

The client and the server checks on the first '\0' byte received that the other side is of the same UID.

It's good enough for gnome-vfs and nautilus, but some of the entry points of the FAM library do not work exactly the same way or are missing, plus the documentation is inexistent, so there is some work left to do but it can be tested right now. The server are autostarted by the library (gam_server) and auto-exits once there isn't any client connected for a while, so contrary to fam it is not a daemon anymore. It works under the uid of the user, using a socked not accessible from the filesystem. The socket name can be modified by setting the FAM_CLIENT_ID environment variable to a unique string. There is another environment variable GAM_DEBUG allowing to debug what's going on the server and the client. The server can also be launched manually gam_server [--notimeout] [FAM_CLIENT_ID] gamin-0.1.10/doc/differences.html0000664014173200001050000001516111112543404013514 00000000000000 Differences from FAM

Differences

gamin should be binary and source code compatible with FAM 2.6.8. However there are some differences and at least one significant extension.

The differences are in term of implementation:

  • No system wide server, instead it relies on per user server, if needed started on demand by the fam/gamin library.
  • The functions FAMSuspendMonitor(), FAMResumeMonitor() and FAMMonitorCollection() are not implemented. They all raise problem of accumulating unbounded state on the server side and better handled at the client level if needed.
  • FAMErrno is provided, but the values may not match their FAM counterparts, similary FamErrlist[] error messages are different.
  • No NFS support based on specific RPC and server, instead gamin monitors only the state as reported locally by the kernel, not that locally done changes on NFS or AFS filesystems are reported on Linux which is the main criteria when having user home directories on such filesystems.

Extension(s)

We tried to limit changes in gamin but a number of features were deemed more important than sticking to the exact same set than FAM:

  • Support for inotify on Linux if compiled in the kernel, this override most of the deficiencies related to dnotify.
  • A lot of debugging support was added both for client and server see the specific page on the matter.
  • The possibility to block Exist/EndExists callbacks when monitoring directories based on a new API, see below

FAM when monitoring a directory, immediately send a set of events listing the files found in that directory, this ends up with an EndExists events. However when monitoring hierarchy it's usually far more efficient and simple to do the scanning on the client side and ignore those directory listing events from the FAM server (the only drawback is a potential mismatch of the directory content between the FAM server and the client). In such a case, all those events are not only superfluous but they are also dangerous since they can lead to a congested pipe to the client which is just scanning directories and not listening to FAM. To that intent we added in gamin 0.0.23 a new API disabling the Exists/EndExists sequences when watching directories for a given FAMConnection:

int FAMNoExists(FAMConnection *fc)

and with the Python bindings:

WatchMonitor.no_exists()

This feature is also used when the client reconnect to the server after a connection loss or if the server died.

Calling it changes the protocol as described below, directory monitoring from that call will only get mutation events and not the initial lists:

The NoExists behaviour change on callbacks

Gamin the File Alteration Monitor

Python bindings

Starting with release 0.0.21, gamin comes with Python bindings. Use "import gamin" to load the module. It exports the main class "WatchMonitor" which handle one connection to the gam_server. Once an instance of the class has been created you can use the watch_directory and watch_file methods to register objects to monitors, and provide the callback to be called when events are generated. Like the FAM API, the python binding API is passive, i.e. one need  to  monitor the file descriptor provided with the get_fd() method to detect events, and call handle_one_event() (blocking) or handle_events() (non-blocking) to process incoming events and get the callbacks appropriately. You can also use the event_pending() method to detect if handle_one_event() would block or not.
Since a short example is worth a thousand words, here is a small session from the python shell:

>>> import gamin
>>>
>>> def callback(path, event):
...     print "Got callback: %s, %s" % (path, event)
...
>>> mon = gamin.WatchMonitor()
>>> mon.watch_directory(".", callback)
<gamin.WatchObject instance at 0xb7f7b56c>
>>> mon.event_pending()
1
>>> mon.handle_one_event()
Got callback: /u/veillard/temp, 8
1
>>> mon.handle_events()
Got callback: bar1, 8
Got callback: foo1, 8
Got callback: /u/veillard/temp, 9
3
>>> mon.stop_watch(".")
>>> del mon

The corresponding standalone code follows:

#!/usr/bin/env python

import gamin
import time

def callback(path, event):
    print "Got callback: %s, %s" % (path, event)

mon = gamin.WatchMonitor()
mon.watch_directory(".", callback)
time.sleep(1)
ret = mon.event_pending()
if ret > 0:
    ret = mon.handle_one_event()
    ret = mon.handle_events()
mon.stop_watch(".")
del mon

Note the addition of the sleep timeout, it is needed because due to the round trip between the client and the gam_server, events may not be immediately available after the monitor creation to the client.

The best way to contact the developers is to use the mailing-list gamin-list@gnome.org.

Before reporting a bug please double-check:

Then the best way is to log the bug in one of the bugzilla or join the list and post there if you think that some of gamin design or code should be changed. If you can provide a testgam scenario reproducing the problem this would really help getting it debugged and fixed, see examples in tests/scenario/ .

Gamin the File Alteration Monitor

Gamin is a file and directory monitoring system defined to be a subset of the FAM (File Alteration Monitor) system. This is a service provided by a library which allows to detect when a file or a directory has been modified.

Overview

Gamin is a file and directory monitoring system defined to be a subset of the FAM (File Alteration Monitor) system.

The main goals of the project are:

  1. minimize the security model of FAM, the daemon runs under the user account, it is compatible with SELinux
  2. simplify the code base, dropping some of the most exotic feature of FAM
  3. provide an API and ABI compatible replacement for FAM
  4. try to fix some other issues like resource consumption

Gamin also serves as an interface to test the inotify mechanism to improve the existing dnotify monitoring interface present in the Linux kernel.

At this point Gamin is fairly tied to Linux, portability is not a primary goal at this stage but if you have portability patches they are welcome.

From an historical point of view, gamin builds from the marmot project authored by James Willcox and Corey Bowers and then heavilly modified to turn it into a minimalist FAM replacement (Francophones will appreciate the filiation from fam to marmot and gamin.)

This library is available under the terms of the GNU LIBRARY GENERAL PUBLIC LICENSE, and a copy of it should be found in the source under the COPYING file.

Using gamin

Basically it is exactly like for using the fam interface. From a programmer point of view this is the same API, and one can make use of the existing FAM documentation.

Configuration

By default gamin should work without needing any configuration, but sometimes using the kernel notification APIs doesn't work or lead to troubles (for example when trying to unmount device). By default gamin revert to using polling for all paths matching /mnt/* or /media/* on Linux. This may be overriden or extended by the one of the three config files /etc/gamin/gaminrc, $HOME/.gaminrc, /etc/gamin/mandatory_gaminrc (note that prior to 0.1.4 only $HOME/.gaminrc was used and fsset was not implemented). Here is an example of such a configuration file:

# configuration for gamin
# Can be used to override the default behaviour.
# notify filepath(s) : indicate to use kernel notification
# poll filepath(s)   : indicate to use polling instead
# fsset fsname method poll_limit : indicate what method of notification for the filesystem
#                                  kernel - use the kernel for notification
#                                  poll - use polling for notification
#                                  none - don't use any notification
#                                  
#                                  the poll_limit is the number of seconds
#                                  that must pass before a resource is polled again.
#                                  It is optional, and if it is not present the previous
#                                  value will be used or the default.
 
notify /mnt/local* /mnt/pictures* # use kernel notification on these paths
poll /temp/*                      # use poll notification on these paths
fsset nfs poll 10                 # use polling on nfs mounts and poll once every 10 seconds

The configuration file accepts only 3 types of command:

  • notify : to express that kernel monitoring should be used for matching paths
  • poll: to express that polling should be used for matching paths
  • fsset: to control what notification method is used on a filesystem type

The three config files are loaded in this order:

  • /etc/gamin/gaminrc
  • ~/.gaminrc
  • /etc/gamin/mandatory_gaminrc

The mandatory config file allows the system administrator to override any potentially dangerous preferences set by the user.

When checking a path to guess whether polling or kernel notification should be used, gamin checks first the user provided rules in their declaration order within the configuration file and then check the predefined rules. This way the first declaration for /mnt/local* in the example override the default one for /mnt/* .

If gamin is not told to use poll on a particular path, it will then try and decide based on the filesystem the path is located on

Caveat: separators in the config file should be spaces, not tabs.

Downloads

You can download gamin from the GNOME project pages, either as sources, and binaries or source RPMs.

Python bindings

Starting with release 0.0.21, gamin comes with Python bindings. Use "import gamin" to load the module. It exports the main class "WatchMonitor" which handle one connection to the gam_server. Once an instance of the class has been created you can use the watch_directory and watch_file methods to register objects to monitors, and provide the callback to be called when events are generated. Like the FAM API, the python binding API is passive, i.e. one need  to  monitor the file descriptor provided with the get_fd() method to detect events, and call handle_one_event() (blocking) or handle_events() (non-blocking) to process incoming events and get the callbacks appropriately. You can also use the event_pending() method to detect if handle_one_event() would block or not.
Since a short example is worth a thousand words, here is a small session from the python shell:

>>> import gamin
>>>
>>> def callback(path, event):
...     print "Got callback: %s, %s" % (path, event)
...
>>> mon = gamin.WatchMonitor()
>>> mon.watch_directory(".", callback)
<gamin.WatchObject instance at 0xb7f7b56c>
>>> mon.event_pending()
1
>>> mon.handle_one_event()
Got callback: /u/veillard/temp, 8
1
>>> mon.handle_events()
Got callback: bar1, 8
Got callback: foo1, 8
Got callback: /u/veillard/temp, 9
3
>>> mon.stop_watch(".")
>>> del mon

The corresponding standalone code follows:

#!/usr/bin/env python

import gamin
import time

def callback(path, event):
    print "Got callback: %s, %s" % (path, event)

mon = gamin.WatchMonitor()
mon.watch_directory(".", callback)
time.sleep(1)
ret = mon.event_pending()
if ret > 0:
    ret = mon.handle_one_event()
    ret = mon.handle_events()
mon.stop_watch(".")
del mon

Note the addition of the sleep timeout, it is needed because due to the round trip between the client and the gam_server, events may not be immediately available after the monitor creation to the client.

Developers informations

The CVS base is in the GNOME project CVS base at cvs.gnome.org, the module name is gamin. See the Gnome CVS Tools page for more information on using CVS.

We expect bug reports to be entered in GNOME bugzilla or in Red Hat bugzilla.

Contacts

The best way to contact the developers is to use the mailing-list gamin-list@gnome.org.

Before reporting a bug please double-check:

Then the best way is to log the bug in one of the bugzilla or join the list and post there if you think that some of gamin design or code should be changed. If you can provide a testgam scenario reproducing the problem this would really help getting it debugged and fixed, see examples in tests/scenario/ .

FAQ

This will be created as user feedback is provided.

Debugging Gamin

Debugging support in gamin:

Both the client and server side, if compiled with debug support accept an environment variable GAM_DEBUG which is set will make them report debugging informations to stdout.

Usually for debugging you also want to use a dedicated server process so setting the GAM_CLIENT_ID environment allows to ensure this. Usually one also want to keep control over the server lifetime and not have it exit automatically after 30 seconds without connection, there is a command line flag --notimeout to gam_server for this.

A typical example of a debugging session using 2 shells would be:

shell1: export GAM_DEBUG=
shell1: gam_server --notimeout test

to run the server in debug mode using the ID "test"

shell2: export GAM_DEBUG=
shell2: export GAM_CLIENT_ID=test
shell2: gamin_client

to run the client in a verbose session. It is perfectly possible to also run the client under a debugger, for the server it works too except the dnotify kernel interface uses a signal SIG33 which is trapped by gdb. To avoid this use the handle gdb instruction:

(gdb) handle SIG33 nostop
Signal        Stop      Print   Pass to program Description
SIG33         No        Yes     Yes             Real-time event 33
(gdb)

even better add it to your $HOME/.gdbinit .

Debugging a running program:

Both the gam_server and client of the gamin library can get switched dynamically to a debug mode by sending them a signal SIGUSR2. In that case the program or library switches to verbose debugging and outputs the traces to a new file /tmp/gamin_debug_XXXXXX . Sending the signal again to the application or the server should switch off debugging.

Debugging and testing client:

A debugging client program called testgam is also available in the tests subdirectory. It allow to use the interface and monitor the flow of event received. Here is an example of a session:

paphio:~/gamin/tests -> export GAMIN_DEBUG_SERVER="../server/gam_server"
paphio:~/gamin/tests -> ./testgam -
> connect test
connected to test
>

The environment variable can be used to specify the path to the server to run, then testgam is launched in interactive mode (argument - ) and the program is asked to connect to the server for session test (the server will be started on-demand by the library if needed).

> mkdir temp
mkdir temp
> mkfile temp/foo
mkfile temp/foo
> mondir temp
mondir temp 0
>
1: /u/veillard/gamin/tests/temp Exists: NULL
1: foo Exists: NULL
1: /u/veillard/gamin/tests/temp EndExist: NULL
> mkfile temp/bar
mkfile temp/bar
>
1: bar Created: NULL
> rmfile temp/foo
rmfile temp/foo
>
1: foo Deleted: NULL
>

In this example a new directory is created with a file in it and then monitored, then the directory content is modified. The testgam program also poll and report events coming from the server as they arrive.

Security

While gamin still use a server to provide the service (ideally if the kernel had a proper interface a library only implementation should be doable and possibly better), it tries to avoid security hazard associated to contacting an external server process:

  • the server runs under the same privilege level as the client, by running under the uid, no root or superuser access is involved, this is checked by both side using kernel support for the checking
  • when possible (e.g. on Linux) the socket used to communicate is not mapped at the filesystem level to avoid risks related to opening a real file, if the kernel doesn't allow this a per user directory holding the socket is used and appropriate rights are checked.
  • to limit DoS attacks done by continuously modifying a monitored resource, the daemon will switch back monitoring of very busy resources to polling with generation of events only once per second.

Here is the process used to acquire and create the sockets:

If there is abstract socket support:

Use the filename "\0/tmp/fam-$USER-$GAM_CLIENT_ID". They are not mapped on the filesystem, no attack is possible that way. The client and the server checks on the first '\0' byte received from the socket that the other side is running under the same UID.

If there is no abstract socket support:

On the server side:

 start:
  try to create /tmp/fam-$USER using mkdir('/tmp/fam-$USER', 007)
  if error:
      make a stat() on it
      if doesn't exist:
          return failure to create
      if user is not getuid() or mode is not 007 or type is not dir:
          try to unlink()
          if error:
              exit with error.
          if success:
              goto start:
                                                                                
  do the socket()/bind() on /tmp/fam-$USER/fam-$GAM_CLIENT_ID

On the client side:

  make a stat on /tmp/fam-$USER
  if doesn't exist:
      return failure to create should start the server
  if user is not getuid() or mode is not 007 or type is not dir:
      try to unlink()
      if error:
          exit with error.
      if success:
          return failure should start the server
  make a stat on /tmp/fam-$USER/fam-$GAM_CLIENT_ID
  if doesn't exist:
      return failure to create should start the server
  if user is not getuid() or type is not socket:
      try to unlink()
      if error:
          exit with error.
      if success:
          return failure should start the server
                                                                                
  do the socket()/connect() on /tmp/fam-$USER/fam-$GAM_CLIENT_ID

The client and the server checks on the first '\0' byte received that the other side is of the same UID.

Internals

gamin uses a client server model, this is in a large measure justified by the inappropriate dnotify kernel API way to signal modification events to an application but also to share kernel signal when multiple application monitors the same resource. It also allow to fine tune and filters event flow in the daemon, potentially minimizing resource consumption in applications.

One server and two client connected

Internally the gam_server maintain various data structures:

  • A tree of monitored nodes, using both GamNode structure containing specific informations (like the path, the subscriptions list for that node, monitoring data and whether it's a directory), the tree itself is based on a GNode N-ary tree.
  • Per connection data (GamConnData) one per connected socket. The data includes state, connection informations (file descriptor, Glib I/O Channel, pid of the application), and potential unprocessed yet data request from the socket.
  • Listener information, keeps the list of subscriptions for the connected application, this could probably be merged in the connection data.
  • For each path monitored by an application, a specific GamSubscription structure is maintained. The subscriptions are referenced both from the monitored nodes tree and from the listeners.

the data structures present in the server

Differences from FAM

Differences

gamin should be binary and source code compatible with FAM 2.6.8. However there are some differences and at least one significant extension.

The differences are in term of implementation:

  • No system wide server, instead it relies on per user server, if needed started on demand by the fam/gamin library.
  • The functions FAMSuspendMonitor(), FAMResumeMonitor() and FAMMonitorCollection() are not implemented. They all raise problem of accumulating unbounded state on the server side and better handled at the client level if needed.
  • FAMErrno is provided, but the values may not match their FAM counterparts, similary FamErrlist[] error messages are different.
  • No NFS support based on specific RPC and server, instead gamin monitors only the state as reported locally by the kernel, not that locally done changes on NFS or AFS filesystems are reported on Linux which is the main criteria when having user home directories on such filesystems.

Extension(s)

We tried to limit changes in gamin but a number of features were deemed more important than sticking to the exact same set than FAM:

  • Support for inotify on Linux if compiled in the kernel, this override most of the deficiencies related to dnotify.
  • A lot of debugging support was added both for client and server see the specific page on the matter.
  • The possibility to block Exist/EndExists callbacks when monitoring directories based on a new API, see below

FAM when monitoring a directory, immediately send a set of events listing the files found in that directory, this ends up with an EndExists events. However when monitoring hierarchy it's usually far more efficient and simple to do the scanning on the client side and ignore those directory listing events from the FAM server (the only drawback is a potential mismatch of the directory content between the FAM server and the client). In such a case, all those events are not only superfluous but they are also dangerous since they can lead to a congested pipe to the client which is just scanning directories and not listening to FAM. To that intent we added in gamin 0.0.23 a new API disabling the Exists/EndExists sequences when watching directories for a given FAMConnection:

int FAMNoExists(FAMConnection *fc)

and with the Python bindings:

WatchMonitor.no_exists()

This feature is also used when the client reconnect to the server after a connection loss or if the server died.

Calling it changes the protocol as described below, directory monitoring from that call will only get mutation events and not the initial lists:

The NoExists behaviour change on callbacks

Gamin the File Alteration Monitor

Overview

Main Menu

Gamin is a file and directory monitoring system defined to be a subset of the FAM (File Alteration Monitor) system.

The main goals of the project are:

  1. minimize the security model of FAM, the daemon runs under the user account, it is compatible with SELinux
  2. simplify the code base, dropping some of the most exotic feature of FAM
  3. provide an API and ABI compatible replacement for FAM
  4. try to fix some other issues like resource consumption

Gamin also serves as an interface to test the inotify mechanism to improve the existing dnotify monitoring interface present in the Linux kernel.

At this point Gamin is fairly tied to Linux, portability is not a primary goal at this stage but if you have portability patches they are welcome.

From an historical point of view, gamin builds from the marmot project authored by James Willcox and Corey Bowers and then heavilly modified to turn it into a minimalist FAM replacement (Francophones will appreciate the filiation from fam to marmot and gamin.)

This library is available under the terms of the GNU LIBRARY GENERAL PUBLIC LICENSE, and a copy of it should be found in the source under the COPYING file.

The environment variable can be used to specify the path to the server to run, then testgam is launched in interactive mode (argument - ) and the program is asked to connect to the server for session test (the server will be started on-demand by the library if needed).

> mkdir temp
mkdir temp
> mkfile temp/foo
mkfile temp/foo
> mondir temp
mondir temp 0
>
1: /u/veillard/gamin/tests/temp Exists: NULL
1: foo Exists: NULL
1: /u/veillard/gamin/tests/temp EndExist: NULL
> mkfile temp/bar
mkfile temp/bar
>
1: bar Created: NULL
> rmfile temp/foo
rmfile temp/foo
>
1: foo Deleted: NULL
>

In this example a new directory is created with a file in it and then monitored, then the directory content is modified. The testgam program also poll and report events coming from the server as they arrive.

It's good enough for gnome-vfs and nautilus, but some of the entry points of the FAM library do not work exactly the same way or are missing, plus the documentation is inexistent, so there is some work left to do but it can be tested right now. The server are autostarted by the library (gam_server) and auto-exits once there isn't any client connected for a while, so contrary to fam it is not a daemon anymore. It works under the uid of the user, using a socked not accessible from the filesystem. The socket name can be modified by setting the FAM_CLIENT_ID environment variable to a unique string. There is another environment variable GAM_DEBUG allowing to debug what's going on the server and the client.

While gamin still use a server to provide the service (ideally if the kernel had a proper interface a library only implementation should be doable and possibly better), it tries to avoid security hazard associated to contacting an external server process:

  • the server runs under the same privilege level as the client, by running under the uid, no root or superuser access is involved, this is checked by both side using kernel support for the checking
  • when possible (e.g. on Linux) the socket used to communicate is not mapped at the filesystem level to avoid risks related to opening a real file, if the kernel doesn't allow this a per user directory holding the socket is used and appropriate rights are checked.
  • to limit DoS attacks done by continuously modifying a monitored resource, the daemon will switch back monitoring of very busy resources to polling with generation of events only once per second.

Here is the process used to acquire and create the sockets:

If there is abstract socket support:

Use the filename "\0/tmp/fam-$USER-$GAM_CLIENT_ID". They are not mapped on the filesystem, no attack is possible that way. The client and the server checks on the first '\0' byte received from the socket that the other side is running under the same UID.

If there is no abstract socket support:

On the server side:

 start:
  try to create /tmp/fam-$USER using mkdir('/tmp/fam-$USER', 007)
  if error:
      make a stat() on it
      if doesn't exist:
          return failure to create
      if user is not getuid() or mode is not 007 or type is not dir:
          try to unlink()
          if error:
              exit with error.
          if success:
              goto start:
                                                                                
  do the socket()/bind() on /tmp/fam-$USER/fam-$GAM_CLIENT_ID

On the client side:

  make a stat on /tmp/fam-$USER
  if doesn't exist:
      return failure to create should start the server
  if user is not getuid() or mode is not 007 or type is not dir:
      try to unlink()
      if error:
          exit with error.
      if success:
          return failure should start the server
  make a stat on /tmp/fam-$USER/fam-$GAM_CLIENT_ID
  if doesn't exist:
      return failure to create should start the server
  if user is not getuid() or type is not socket:
      try to unlink()
      if error:
          exit with error.
      if success:
          return failure should start the server
                                                                                
  do the socket()/connect() on /tmp/fam-$USER/fam-$GAM_CLIENT_ID

The client and the server checks on the first '\0' byte received that the other side is of the same UID.

Differences from FAM

Differences

gamin should be binary and source code compatible with FAM 2.6.8. However there are some differences and at least one significant extension.

The differences are in term of implementation:

  • No system wide server, instead it relies on per user server, if needed started on demand by the fam/gamin library.
  • The functions FAMSuspendMonitor(), FAMResumeMonitor() and FAMMonitorCollection() are not implemented. They all raise problem of accumulating unbounded state on the server side and better handled at the client level if needed.
  • FAMErrno is provided, but the values may not match their FAM counterparts, similary FamErrlist[] error messages are different.
  • No NFS support based on specific RPC and server, instead gamin monitors only the state as reported locally by the kernel, not that locally done changes on NFS or AFS filesystems are reported on Linux which is the main criteria when having user home directories on such filesystems.

Extension(s)

We tried to limit changes in gamin but a number of features were deemed more important than sticking to the exact same set than FAM:

  • Support for inotify on Linux if compiled in the kernel, this override most of the deficiencies related to dnotify.
  • A lot of debugging support was added both for client and server see the specific page on the matter.
  • The possibility to block Exist/EndExists callbacks when monitoring directories based on a new API, see below

FAM when monitoring a directory, immediately send a set of events listing the files found in that directory, this ends up with an EndExists events. However when monitoring hierarchy it's usually far more efficient and simple to do the scanning on the client side and ignore those directory listing events from the FAM server (the only drawback is a potential mismatch of the directory content between the FAM server and the client). In such a case, all those events are not only superfluous but they are also dangerous since they can lead to a congested pipe to the client which is just scanning directories and not listening to FAM. To that intent we added in gamin 0.0.23 a new API disabling the Exists/EndExists sequences when watching directories for a given FAMConnection:

int FAMNoExists(FAMConnection *fc)

and with the Python bindings:

WatchMonitor.no_exists()

This feature is also used when the client reconnect to the server after a connection loss or if the server died.

Calling it changes the protocol as described below, directory monitoring from that call will only get mutation events and not the initial lists:

The NoExists behaviour change on callbacks

gamin uses a client server model, this is in a large measure justified by the inappropriate dnotify kernel API way to signal modification events to an application but also to share kernel signal when multiple application monitors the same resource. It also allow to fine tune and filters event flow in the daemon, potentially minimizing resource consumption in applications.

One server and two client connected

Internally the gam_server maintain various data structures:

  • A tree of monitored nodes, using both GamNode structure containing specific informations (like the path, the subscriptions list for that node, monitoring data and whether it's a directory), the tree itself is based on a GNode N-ary tree.
  • Per connection data (GamConnData) one per connected socket. The data includes state, connection informations (file descriptor, Glib I/O Channel, pid of the application), and potential unprocessed yet data request from the socket.
  • Listener information, keeps the list of subscriptions for the connected application, this could probably be merged in the connection data.
  • For each path monitored by an application, a specific GamSubscription structure is maintained. The subscriptions are referenced both from the monitored nodes tree and from the listeners.

the data structures present in the server

Configuration

Main Menu

By default gamin should work without needing any configuration, but sometimes using the kernel notification APIs doesn't work or lead to troubles (for example when trying to unmount device). By default gamin revert to using polling for all paths matching /mnt/* or /media/* on Linux. This may be overriden or extended by the one of the three config files /etc/gamin/gaminrc, $HOME/.gaminrc, /etc/gamin/mandatory_gaminrc (note that prior to 0.1.4 only $HOME/.gaminrc was used and fsset was not implemented). Here is an example of such a configuration file:

# configuration for gamin
# Can be used to override the default behaviour.
# notify filepath(s) : indicate to use kernel notification
# poll filepath(s)   : indicate to use polling instead
# fsset fsname method poll_limit : indicate what method of notification for the filesystem
#                                  kernel - use the kernel for notification
#                                  poll - use polling for notification
#                                  none - don't use any notification
#                                  
#                                  the poll_limit is the number of seconds
#                                  that must pass before a resource is polled again.
#                                  It is optional, and if it is not present the previous
#                                  value will be used or the default.
 
notify /mnt/local* /mnt/pictures* # use kernel notification on these paths
poll /temp/*                      # use poll notification on these paths
fsset nfs poll 10                 # use polling on nfs mounts and poll once every 10 seconds

The configuration file accepts only 3 types of command:

  • notify : to express that kernel monitoring should be used for matching paths
  • poll: to express that polling should be used for matching paths
  • fsset: to control what notification method is used on a filesystem type

The three config files are loaded in this order:

  • /etc/gamin/gaminrc
  • ~/.gaminrc
  • /etc/gamin/mandatory_gaminrc

The mandatory config file allows the system administrator to override any potentially dangerous preferences set by the user.

When checking a path to guess whether polling or kernel notification should be used, gamin checks first the user provided rules in their declaration order within the configuration file and then check the predefined rules. This way the first declaration for /mnt/local* in the example override the default one for /mnt/* .

If gamin is not told to use poll on a particular path, it will then try and decide based on the filesystem the path is located on

Caveat: separators in the config file should be spaces, not tabs.

The best way to contact the developers is to use the mailing-list gamin-list@gnome.org.

Before reporting a bug please double-check:

Then the best way is to log the bug in one of the bugzilla or join the list and post there if you think that some of gamin design or code should be changed. If you can provide a testgam scenario reproducing the problem this would really help getting it debugged and fixed, see examples in tests/scenario/ .

Python bindings

Starting with release 0.0.21, gamin comes with Python bindings. Use "import gamin" to load the module. It exports the main class "WatchMonitor" which handle one connection to the gam_server. Once an instance of the class has been created you can use the watch_directory and watch_file methods to register objects to monitors, and provide the callback to be called when events are generated. Like the FAM API, the python binding API is passive, i.e. one need  to  monitor the file descriptor provided with the get_fd() method to detect events, and call handle_one_event() (blocking) or handle_events() (non-blocking) to process incoming events and get the callbacks appropriately. You can also use the event_pending() method to detect if handle_one_event() would block or not.
Since a short example is worth a thousand words, here is a small session from the python shell:

>>> import gamin
>>>
>>> def callback(path, event):
...     print "Got callback: %s, %s" % (path, event)
...
>>> mon = gamin.WatchMonitor()
>>> mon.watch_directory(".", callback)
<gamin.WatchObject instance at 0xb7f7b56c>
>>> mon.event_pending()
1
>>> mon.handle_one_event()
Got callback: /u/veillard/temp, 8
1
>>> mon.handle_events()
Got callback: bar1, 8
Got callback: foo1, 8
Got callback: /u/veillard/temp, 9
3
>>> mon.stop_watch(".")
>>> del mon

The corresponding standalone code follows:

#!/usr/bin/env python

import gamin
import time

def callback(path, event):
    print "Got callback: %s, %s" % (path, event)

mon = gamin.WatchMonitor()
mon.watch_directory(".", callback)
time.sleep(1)
ret = mon.event_pending()
if ret > 0:
    ret = mon.handle_one_event()
    ret = mon.handle_events()
mon.stop_watch(".")
del mon

Note the addition of the sleep timeout, it is needed because due to the round trip between the client and the gam_server, events may not be immediately available after the monitor creation to the client.

Gamin is a file and directory monitoring system defined to be a subset of the FAM (File Alteration Monitor) system. This is a service provided by a library which allows to detect when a file or a directory has been modified.

Gamin the File Alteration Monitor

By default gamin should work without needing any configuration, but sometimes using the kernel notification APIs doesn't work or lead to troubles (for example when trying to unmount device). By default gamin revert to using polling for all paths matching /mnt/* or /media/* on Linux. This may be overriden or extended by the one of the three config files /etc/gamin/gaminrc, $HOME/.gaminrc, /etc/gamin/mandatory_gaminrc (note that prior to 0.1.4 only $HOME/.gaminrc was used and fsset was not implemented). Here is an example of such a configuration file:

# configuration for gamin
# Can be used to override the default behaviour.
# notify filepath(s) : indicate to use kernel notification
# poll filepath(s)   : indicate to use polling instead
# fsset fsname method poll_limit : indicate what method of notification for the filesystem
#                                  kernel - use the kernel for notification
#                                  poll - use polling for notification
#                                  none - don't use any notification
#                                  
#                                  the poll_limit is the number of seconds
#                                  that must pass before a resource is polled again.
#                                  It is optional, and if it is not present the previous
#                                  value will be used or the default.
 
notify /mnt/local* /mnt/pictures* # use kernel notification on these paths
poll /temp/*                      # use poll notification on these paths
fsset nfs poll 10                 # use polling on nfs mounts and poll once every 10 seconds

The configuration file accepts only 3 types of command:

  • notify : to express that kernel monitoring should be used for matching paths
  • poll: to express that polling should be used for matching paths
  • fsset: to control what notification method is used on a filesystem type

The three config files are loaded in this order:

  • /etc/gamin/gaminrc
  • ~/.gaminrc
  • /etc/gamin/mandatory_gaminrc

The mandatory config file allows the system administrator to override any potentially dangerous preferences set by the user.

When checking a path to guess whether polling or kernel notification should be used, gamin checks first the user provided rules in their declaration order within the configuration file and then check the predefined rules. This way the first declaration for /mnt/local* in the example override the default one for /mnt/* .

If gamin is not told to use poll on a particular path, it will then try and decide based on the filesystem the path is located on

Caveat: separators in the config file should be spaces, not tabs.

Gamin the File Alteration Monitor

Gamin is a file and directory monitoring system defined to be a subset of the FAM (File Alteration Monitor) system. This is a service provided by a library which allows to detect when a file or a directory has been modified.

Overview

Gamin is a file and directory monitoring system defined to be a subset of the FAM (File Alteration Monitor) system.

The main goals of the project are:

  1. minimize the security model of FAM, the daemon runs under the user account, it is compatible with SELinux
  2. simplify the code base, dropping some of the most exotic feature of FAM
  3. provide an API and ABI compatible replacement for FAM
  4. try to fix some other issues like resource consumption

Gamin also serves as an interface to test the inotify mechanism to improve the existing dnotify monitoring interface present in the Linux kernel.

At this point Gamin is fairly tied to Linux, portability is not a primary goal at this stage but if you have portability patches they are welcome.

From an historical point of view, gamin builds from the marmot project authored by James Willcox and Corey Bowers and then heavilly modified to turn it into a minimalist FAM replacement (Francophones will appreciate the filiation from fam to marmot and gamin.)

This library is available under the terms of the GNU LIBRARY GENERAL PUBLIC LICENSE, and a copy of it should be found in the source under the COPYING file.

Using gamin

Basically it is exactly like for using the fam interface. From a programmer point of view this is the same API, and one can make use of the existing FAM documentation.

Configuration

By default gamin should work without needing any configuration, but sometimes using the kernel notification APIs doesn't work or lead to troubles (for example when trying to unmount device). By default gamin revert to using polling for all paths matching /mnt/* or /media/* on Linux. This may be overriden or extended by the one of the three config files /etc/gamin/gaminrc, $HOME/.gaminrc, /etc/gamin/mandatory_gaminrc (note that prior to 0.1.4 only $HOME/.gaminrc was used and fsset was not implemented). Here is an example of such a configuration file:

# configuration for gamin
# Can be used to override the default behaviour.
# notify filepath(s) : indicate to use kernel notification
# poll filepath(s)   : indicate to use polling instead
# fsset fsname method poll_limit : indicate what method of notification for the filesystem
#                                  kernel - use the kernel for notification
#                                  poll - use polling for notification
#                                  none - don't use any notification
#                                  
#                                  the poll_limit is the number of seconds
#                                  that must pass before a resource is polled again.
#                                  It is optional, and if it is not present the previous
#                                  value will be used or the default.
 
notify /mnt/local* /mnt/pictures* # use kernel notification on these paths
poll /temp/*                      # use poll notification on these paths
fsset nfs poll 10                 # use polling on nfs mounts and poll once every 10 seconds

The configuration file accepts only 3 types of command:

  • notify : to express that kernel monitoring should be used for matching paths
  • poll: to express that polling should be used for matching paths
  • fsset: to control what notification method is used on a filesystem type

The three config files are loaded in this order:

  • /etc/gamin/gaminrc
  • ~/.gaminrc
  • /etc/gamin/mandatory_gaminrc

The mandatory config file allows the system administrator to override any potentially dangerous preferences set by the user.

When checking a path to guess whether polling or kernel notification should be used, gamin checks first the user provided rules in their declaration order within the configuration file and then check the predefined rules. This way the first declaration for /mnt/local* in the example override the default one for /mnt/* .

If gamin is not told to use poll on a particular path, it will then try and decide based on the filesystem the path is located on

Caveat: separators in the config file should be spaces, not tabs.

Downloads

You can download gamin from the GNOME project pages, either as sources, and binaries or source RPMs.

Python bindings

Starting with release 0.0.21, gamin comes with Python bindings. Use "import gamin" to load the module. It exports the main class "WatchMonitor" which handle one connection to the gam_server. Once an instance of the class has been created you can use the watch_directory and watch_file methods to register objects to monitors, and provide the callback to be called when events are generated. Like the FAM API, the python binding API is passive, i.e. one need  to  monitor the file descriptor provided with the get_fd() method to detect events, and call handle_one_event() (blocking) or handle_events() (non-blocking) to process incoming events and get the callbacks appropriately. You can also use the event_pending() method to detect if handle_one_event() would block or not.
Since a short example is worth a thousand words, here is a small session from the python shell:

>>> import gamin
>>>
>>> def callback(path, event):
...     print "Got callback: %s, %s" % (path, event)
...
>>> mon = gamin.WatchMonitor()
>>> mon.watch_directory(".", callback)
<gamin.WatchObject instance at 0xb7f7b56c>
>>> mon.event_pending()
1
>>> mon.handle_one_event()
Got callback: /u/veillard/temp, 8
1
>>> mon.handle_events()
Got callback: bar1, 8
Got callback: foo1, 8
Got callback: /u/veillard/temp, 9
3
>>> mon.stop_watch(".")
>>> del mon

The corresponding standalone code follows:

#!/usr/bin/env python

import gamin
import time

def callback(path, event):
    print "Got callback: %s, %s" % (path, event)

mon = gamin.WatchMonitor()
mon.watch_directory(".", callback)
time.sleep(1)
ret = mon.event_pending()
if ret > 0:
    ret = mon.handle_one_event()
    ret = mon.handle_events()
mon.stop_watch(".")
del mon

Note the addition of the sleep timeout, it is needed because due to the round trip between the client and the gam_server, events may not be immediately available after the monitor creation to the client.

Developers informations

The CVS base is in the GNOME project CVS base at cvs.gnome.org, the module name is gamin. See the Gnome CVS Tools page for more information on using CVS.

We expect bug reports to be entered in GNOME bugzilla or in Red Hat bugzilla.

Contacts

The best way to contact the developers is to use the mailing-list gamin-list@gnome.org.

Before reporting a bug please double-check:

Then the best way is to log the bug in one of the bugzilla or join the list and post there if you think that some of gamin design or code should be changed. If you can provide a testgam scenario reproducing the problem this would really help getting it debugged and fixed, see examples in tests/scenario/ .

FAQ

This will be created as user feedback is provided.

Debugging Gamin

Debugging support in gamin:

Both the client and server side, if compiled with debug support accept an environment variable GAM_DEBUG which is set will make them report debugging informations to stdout.

Usually for debugging you also want to use a dedicated server process so setting the GAM_CLIENT_ID environment allows to ensure this. Usually one also want to keep control over the server lifetime and not have it exit automatically after 30 seconds without connection, there is a command line flag --notimeout to gam_server for this.

A typical example of a debugging session using 2 shells would be:

shell1: export GAM_DEBUG=
shell1: gam_server --notimeout test

to run the server in debug mode using the ID "test"

shell2: export GAM_DEBUG=
shell2: export GAM_CLIENT_ID=test
shell2: gamin_client

to run the client in a verbose session. It is perfectly possible to also run the client under a debugger, for the server it works too except the dnotify kernel interface uses a signal SIG33 which is trapped by gdb. To avoid this use the handle gdb instruction:

(gdb) handle SIG33 nostop
Signal        Stop      Print   Pass to program Description
SIG33         No        Yes     Yes             Real-time event 33
(gdb)

even better add it to your $HOME/.gdbinit .

Debugging a running program:

Both the gam_server and client of the gamin library can get switched dynamically to a debug mode by sending them a signal SIGUSR2. In that case the program or library switches to verbose debugging and outputs the traces to a new file /tmp/gamin_debug_XXXXXX . Sending the signal again to the application or the server should switch off debugging.

Debugging and testing client:

A debugging client program called testgam is also available in the tests subdirectory. It allow to use the interface and monitor the flow of event received. Here is an example of a session:

paphio:~/gamin/tests -> export GAMIN_DEBUG_SERVER="../server/gam_server"
paphio:~/gamin/tests -> ./testgam -
> connect test
connected to test
>

The environment variable can be used to specify the path to the server to run, then testgam is launched in interactive mode (argument - ) and the program is asked to connect to the server for session test (the server will be started on-demand by the library if needed).

> mkdir temp
mkdir temp
> mkfile temp/foo
mkfile temp/foo
> mondir temp
mondir temp 0
>
1: /u/veillard/gamin/tests/temp Exists: NULL
1: foo Exists: NULL
1: /u/veillard/gamin/tests/temp EndExist: NULL
> mkfile temp/bar
mkfile temp/bar
>
1: bar Created: NULL
> rmfile temp/foo
rmfile temp/foo
>
1: foo Deleted: NULL
>

In this example a new directory is created with a file in it and then monitored, then the directory content is modified. The testgam program also poll and report events coming from the server as they arrive.

Security

While gamin still use a server to provide the service (ideally if the kernel had a proper interface a library only implementation should be doable and possibly better), it tries to avoid security hazard associated to contacting an external server process:

  • the server runs under the same privilege level as the client, by running under the uid, no root or superuser access is involved, this is checked by both side using kernel support for the checking
  • when possible (e.g. on Linux) the socket used to communicate is not mapped at the filesystem level to avoid risks related to opening a real file, if the kernel doesn't allow this a per user directory holding the socket is used and appropriate rights are checked.
  • to limit DoS attacks done by continuously modifying a monitored resource, the daemon will switch back monitoring of very busy resources to polling with generation of events only once per second.

Here is the process used to acquire and create the sockets:

If there is abstract socket support:

Use the filename "\0/tmp/fam-$USER-$GAM_CLIENT_ID". They are not mapped on the filesystem, no attack is possible that way. The client and the server checks on the first '\0' byte received from the socket that the other side is running under the same UID.

If there is no abstract socket support:

On the server side:

 start:
  try to create /tmp/fam-$USER using mkdir('/tmp/fam-$USER', 007)
  if error:
      make a stat() on it
      if doesn't exist:
          return failure to create
      if user is not getuid() or mode is not 007 or type is not dir:
          try to unlink()
          if error:
              exit with error.
          if success:
              goto start:
                                                                                
  do the socket()/bind() on /tmp/fam-$USER/fam-$GAM_CLIENT_ID

On the client side:

  make a stat on /tmp/fam-$USER
  if doesn't exist:
      return failure to create should start the server
  if user is not getuid() or mode is not 007 or type is not dir:
      try to unlink()
      if error:
          exit with error.
      if success:
          return failure should start the server
  make a stat on /tmp/fam-$USER/fam-$GAM_CLIENT_ID
  if doesn't exist:
      return failure to create should start the server
  if user is not getuid() or type is not socket:
      try to unlink()
      if error:
          exit with error.
      if success:
          return failure should start the server
                                                                                
  do the socket()/connect() on /tmp/fam-$USER/fam-$GAM_CLIENT_ID

The client and the server checks on the first '\0' byte received that the other side is of the same UID.

Internals

gamin uses a client server model, this is in a large measure justified by the inappropriate dnotify kernel API way to signal modification events to an application but also to share kernel signal when multiple application monitors the same resource. It also allow to fine tune and filters event flow in the daemon, potentially minimizing resource consumption in applications.

One server and two client connected

Internally the gam_server maintain various data structures:

  • A tree of monitored nodes, using both GamNode structure containing specific informations (like the path, the subscriptions list for that node, monitoring data and whether it's a directory), the tree itself is based on a GNode N-ary tree.
  • Per connection data (GamConnData) one per connected socket. The data includes state, connection informations (file descriptor, Glib I/O Channel, pid of the application), and potential unprocessed yet data request from the socket.
  • Listener information, keeps the list of subscriptions for the connected application, this could probably be merged in the connection data.
  • For each path monitored by an application, a specific GamSubscription structure is maintained. The subscriptions are referenced both from the monitored nodes tree and from the listeners.

the data structures present in the server

Differences from FAM

Differences

gamin should be binary and source code compatible with FAM 2.6.8. However there are some differences and at least one significant extension.

The differences are in term of implementation:

  • No system wide server, instead it relies on per user server, if needed started on demand by the fam/gamin library.
  • The functions FAMSuspendMonitor(), FAMResumeMonitor() and FAMMonitorCollection() are not implemented. They all raise problem of accumulating unbounded state on the server side and better handled at the client level if needed.
  • FAMErrno is provided, but the values may not match their FAM counterparts, similary FamErrlist[] error messages are different.
  • No NFS support based on specific RPC and server, instead gamin monitors only the state as reported locally by the kernel, not that locally done changes on NFS or AFS filesystems are reported on Linux which is the main criteria when having user home directories on such filesystems.

Extension(s)

We tried to limit changes in gamin but a number of features were deemed more important than sticking to the exact same set than FAM:

  • Support for inotify on Linux if compiled in the kernel, this override most of the deficiencies related to dnotify.
  • A lot of debugging support was added both for client and server see the specific page on the matter.
  • The possibility to block Exist/EndExists callbacks when monitoring directories based on a new API, see below

FAM when monitoring a directory, immediately send a set of events listing the files found in that directory, this ends up with an EndExists events. However when monitoring hierarchy it's usually far more efficient and simple to do the scanning on the client side and ignore those directory listing events from the FAM server (the only drawback is a potential mismatch of the directory content between the FAM server and the client). In such a case, all those events are not only superfluous but they are also dangerous since they can lead to a congested pipe to the client which is just scanning directories and not listening to FAM. To that intent we added in gamin 0.0.23 a new API disabling the Exists/EndExists sequences when watching directories for a given FAMConnection:

int FAMNoExists(FAMConnection *fc)

and with the Python bindings:

WatchMonitor.no_exists()

This feature is also used when the client reconnect to the server after a connection loss or if the server died.

Calling it changes the protocol as described below, directory monitoring from that call will only get mutation events and not the initial lists:

The NoExists behaviour change on callbacks

Gamin the File Alteration Monitor

Overview

Main Menu
Related links

Gamin is a file and directory monitoring system defined to be a subset of the FAM (File Alteration Monitor) system.

The main goals of the project are:

  1. minimize the security model of FAM, the daemon runs under the user account, it is compatible with SELinux
  2. simplify the code base, dropping some of the most exotic feature of FAM
  3. provide an API and ABI compatible replacement for FAM
  4. try to fix some other issues like resource consumption

Gamin also serves as an interface to test the inotify mechanism to improve the existing dnotify monitoring interface present in the Linux kernel.

At this point Gamin is fairly tied to Linux, portability is not a primary goal at this stage but if you have portability patches they are welcome.

From an historical point of view, gamin builds from the marmot project authored by James Willcox and Corey Bowers and then heavilly modified to turn it into a minimalist FAM replacement (Francophones will appreciate the filiation from fam to marmot and gamin.)

This library is available under the terms of the GNU LIBRARY GENERAL PUBLIC LICENSE, and a copy of it should be found in the source under the COPYING file.

Usually for debugging you also want to use a dedicated server process so setting the GAM_CLIENT_ID environment allows to ensure this. Usually one also want to keep control over the server lifetime and not have it exit automatically after 30 seconds without connection, there is a command line flag --notimeout to gam_server for this. a typical example of a debugging session using 2 shells would be shell1: export GAM_DEBUG= shell1: gam_server --notimeout test running the server in debug mode using the ID "test" shell2: export GAM_DEBUG= shell2: export GAM_CLIENT_ID=test shell2: gamin_client this will run a verbose session.

Debugging support in gamin:

Both the client and server side, if compiled with debug support accept an environment variable GAM_DEBUG which is set will make them report debugging informations to stdout.

Usually for debugging you also want to use a dedicated server process so setting the GAM_CLIENT_ID environment allows to ensure this. Usually one also want to keep control over the server lifetime and not have it exit automatically after 30 seconds without connection, there is a command line flag --notimeout to gam_server for this.

A typical example of a debugging session using 2 shells would be:

shell1: export GAM_DEBUG=
shell1: gam_server --notimeout test

to run the server in debug mode using the ID "test"

shell2: export GAM_DEBUG=
shell2: export GAM_CLIENT_ID=test
shell2: gamin_client

to run the client in a verbose session. It is perfectly possible to also run the client under a debugger, for the server it works too except the dnotify kernel interface uses a signal SIG33 which is trapped by gdb. To avoid this use the handle gdb instruction:

(gdb) handle SIG33 nostop
Signal        Stop      Print   Pass to program Description
SIG33         No        Yes     Yes             Real-time event 33
(gdb)

even better add it to your $HOME/.gdbinit .

Debugging a running program:

Both the gam_server and client of the gamin library can get switched dynamically to a debug mode by sending them a signal SIGUSR2. In that case the program or library switches to verbose debugging and outputs the traces to a new file /tmp/gamin_debug_XXXXXX . Sending the signal again to the application or the server should switch off debugging.

Debugging and testing client:

A debugging client program called testgam is also available in the tests subdirectory. It allow to use the interface and monitor the flow of event received. Here is an example of a session:

paphio:~/gamin/tests -> export GAMIN_DEBUG_SERVER="../server/gam_server"
paphio:~/gamin/tests -> ./testgam -
> connect test
connected to test
>

The environment variable can be used to specify the path to the server to run, then testgam is launched in interactive mode (argument - ) and the program is asked to connect to the server for session test (the server will be started on-demand by the library if needed).

> mkdir temp
mkdir temp
> mkfile temp/foo
mkfile temp/foo
> mondir temp
mondir temp 0
>
1: /u/veillard/gamin/tests/temp Exists: NULL
1: foo Exists: NULL
1: /u/veillard/gamin/tests/temp EndExist: NULL
> mkfile temp/bar
mkfile temp/bar
>
1: bar Created: NULL
> rmfile temp/foo
rmfile temp/foo
>
1: foo Deleted: NULL
>

In this example a new directory is created with a file in it and then monitored, then the directory content is modified. The testgam program also poll and report events coming from the server as they arrive.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

What was happening was that we were calling gam_poll_add_subscription in that case, but when the dnotify backend is enabled the poll backend is in a different mode. So these subscriptions was never consumed. I special cased for when inotify is not running to call the backend_add_subscription even when the item is on the exclude list. The dnotify backend has code to deal with excluded subscriptions.

This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.) If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You only need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not support the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the `--target=TYPE' option to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc will cause the specified gcc to be used as the C compiler (unless it is overridden in the site shell script). `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details.
