Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, 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 redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's 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 give any other recipients of the Program a copy of this License along with the Program. 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 Program or any portion of it, thus forming a work based on the Program, 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) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, 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 Program, 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 Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) 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; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, 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 executable. 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. If distribution of executable or 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 counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program 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. 5. 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 Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program 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. 7. 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 Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program 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 Program. 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. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program 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. 9. The Free Software Foundation may publish revised and/or new versions of the 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 Program 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 Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, 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 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. 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. Copyright (C) 19yy 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 of the License, 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. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. incron-0.5.12/LICENSE-LGPL000066400000000000000000000635001343252311100146270ustar00rootroot00000000000000 GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. 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 other code 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. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. 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, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser 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 combine 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) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) 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. d) 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. e) 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 materials to be 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 with 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 Lesser 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.

About 2. Install a binary version 3. Obtain the source code 4. Requirements 5. How to build 6. How to use 7. Bugs, suggestions 8. Licensing 1. About ======== This program is the "inotify cron" system. It consist of a daemon and a table manipulator. You can use it a similar way as the regular cron. The difference is that the inotify cron handles filesystem events rather than time periods. This project was kicked off by Lukas Jelinek in 2006 and then unfortunatally abandoned in 2012. Upstream development and bug-tracking/fixing continued in 2014 on GitHub: https://github.com/ar-/incron . 2. Install a binary version =========================== On Debian and Ubuntu based systems you can install this software with sudo apt-get install incron On all other Linux based systems you have to build it from source. 3. Obtain the source code ========================= You can download the latest stable version from https://github.com/ar-/incron/archive/master.tar.gz You can download older versions from https://github.com/ar-/incron/releases 4. Requirements =============== * Linux kernel 2.6.13 or later (with inotify compiled in) * inotify headers (inotify.h, sometimes inotify-syscalls.h) installed in /sys. The most common place is /usr/include/sys. * GCC 4.x compiler (probably works also with GCC 3.4, possibly with older versions too) 5. How to build =============== Short: make -j8 && sudo make install Long: This software does not contain a standard portable build mechanism. There is only a Makefile which may be modified manually. On many Linux systems you need not to change anything. Please review the Makefile BEFORE you type 'make'. Especially check the PREFIX and other common variables. If done you can now build the files ('make'). The binaries must be of course installed as root. If you want to use (after editing) the example configuration file simply rename it from /etc/incron.conf.example to /etc/incron.conf (you can also use -f for one-time use of a custom configuration file). Making a release of the source tree relies on the 'VERSION' file. The file should contain only a simple version string such as '0.5.9' or (if you wish) something more comlex (e.g. '0.5.9-improved'). The doxygen program must be installed and its control file 'Doxygen' created for generating the API documentation. 6. How to use ============= The incron daemon (incrond) must be run under root (typically from runlevel script etc.). It loads the current user tables and hooks them for later changes. The incron table manipulator may be run under any regular user since it SUIDs. For manipulation with the tables use basically the same syntax as for the crontab program. You can import a table, remove and edit the current table. The user table rows have the following syntax: Where: is a filesystem path (currently avoid whitespaces!) is a symbolic (see inotify.h; use commas for separating symbols) or numeric mask for events is an application or script to run on the events The command may contain these wildcards: $$ - a dollar sign $@ - the watched filesystem path (see above) $# - the event-related file name $% - the event flags (textually) $& - the event flags (numerically) The mask may additionaly contain a special symbol loopable=true which disables events occurred during the event handling (to avoid loops). It also may contain recursive=false to ignore sub-directories. The mask can also be extended by dotdirs=true which will include dotdirectories (hidden directories and hidden files) into the search. **Example 1**: You need to run program 'abc' with the full file path as an argument every time a file is changed in /var/mail. One of the solutions follows: /var/mail IN_CLOSE_WRITE abc $@/$# Example 2: You need to run program 'efg' with the full file path as the first argument and the numeric event flags as the second one. It have to monitor all events on files in /tmp. Here is it: /tmp IN_ALL_EVENTS efg $@/$# $& Since 0.4.0 also system tables are supported. They are located in /etc/incron.d and their commands use root privileges. System tables are intended to be changed directly (without incrontab). Some parameters of both incrontab and incrond can be changed by the configuration. See the example file for more information. Example 3: You need to run program 'playmp3' with the full file path as an argument every time a MP3 file is moved to in /home/u1/Music. One of the solutions follows: /home/u1/Music/*.mp3 IN_MOVED_TO playmp3 $@/$# Example 4: You need to observe the directory /etc/ recursively and report every change in the syslog. One of the solutions follows: /etc/ IN_CLOSE_WRITE echo $@/$# | logger Example 5: You need to observe the directory /etc/apache but exclude the sub-directories and report every change in the syslog. One of the solutions follows: /etc/apache IN_CLOSE_WRITE,recursive=false echo $@/$# | logger Example 6: You need to observe the directory /home/user1 recursively, including all the hidden sub-directories and hidden files (dotfiles/dotdirectories) and report every change in the syslog. One of the solutions follows: /home/user1 IN_CLOSE_WRITE,dotdirs=true echo $@/$# | logger 7. Bugs, suggestions ==================== incrond is currently not resistent against looping. If you find a bug or have a suggestion how to improve the program, please use the bug tracking system at https://github.com/ar-/incron/issues. 8.

Install a binary version =========================== On Debian and Ubuntu based systems you can install this software (the version maintained by Debian) with sudo apt-get install incron There is a daily build running on Launchpad. You can install that build from a PPA in Ubuntu, to have always an up-to-date build. sudo add-apt-repository ppa:altair-ibn-la-ahad/incron sudo apt-get update sudo apt-get install incron For more information follow the link to the PPA: https://code.launchpad.net/~altair-ibn-la-ahad/+archive/ubuntu/incron The build logs are available here: https://code.launchpad.net/~altair-ibn-la-ahad/+recipe/incron-daily On all other Linux based systems you have to build it from source. If you would like to add a build script for other linux flavors (Gentoo, Suse, Ret Hat, ...) please send me a pull request. I will be happy to include it. 3.

It's use is generally similar to \fIcron\fR(8). \fIincrond\fR can be started from /etc/rc, /etc/rc.local and so on. It daemonizes itself (returns immediately) and doesn't need to be started with & and through \fInohup\fR(1). It can be run on foreground too. \fIincrond\fR uses two categories of tables \fIincrontab\fR(5). System tables are usually located in /etc/incron.d and are maintained outside of incron (e.g. by various applications). These tables work on root rights level and thus any file may be watched and commands are executed with root privileges. User tables are located in /var/spool/incron by default and have names based on user accounts. These tables use users' access rights, thus only files which the user may access are watched. Commands are executed with users' privileges. If a table (incrontab) is changed \fIincrond\fR reacts immediately and reloads the table. Currently running child processes (commands) are not affected. There are two files determining whether an user is allowed to use incron. These files have very simple syntax \- one user name per line. If /etc/incron.allow exists the user must be noted there to be allowed to use incron. Otherwise if /etc/incron.deny exists the user must not be noted there to use incron. If none of these files exists there is no other restriction whether anybody may use incron. Location of these files can be changed in the configuration. The daemon itself is currently not protected against looping. If a command executed due to an event causes the same event it leads to an infinite loop unless a flag mask containing loopable=true is specified. Please beware of this and do not allow permission for use incron to unreliable users. \fB\-n\fR (or \fB\-\-foreground\fR) option causes running on foreground. This is useful especially for testing, debugging and optimization. \fB\-k\fR (or \fB\-\-kill\fR) option terminates a running instance of \fBincrond\fR. \fB\-f \fR (or \fB\-\-config=\fR) option specifies another location for the configuration file (/etc/incron.conf is used by default). \fBEnvironment variables:\fR For system tables, the default (the same as for incrond itself) environment variable set is used. The same applies to root's table. For non\-root user tables, the whole environment is cleared and then only these variables are set: LOGNAME, USER, USERNAME, SHELL, HOME and PATH. The variables (except PATH) take values from the user database (e.g. /etc/passwd). The PATH variable is set to /usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin. .SH "SEE ALSO" incrontab(1), incrontab(5), incron.conf(5) .SH "BUGS" incrond is currently not resistent against looping. .SH "AUTHOR" Andreas Altair Redmer (please report bugs to https://github.com/ar-/incron/issues ).

It creates, removes, modifies and lists user tables (\fIincrontab\fR(5)). Each user (including even system users without home directories) has an incron table which can't be manipulated directly (only root can effectively change these tables and is NOT recommended to do so). All informational messages of this program are printed to the standard error output (stderr). If \fI/etc/incron.allow\fR exists only users listed here may use incron. Otherwise if \fI/etc/incron.deny\fR exists only users NOT listed here may use incron. If none of these files exists everyone is allowed to use incron. (\fBImportant note:\fR This behavior is insecure and will be probably changed to be compatible with the style used by ISC Cron.) Location of these files can be changed in the configuration. The first form of this command imports a file, validates it and stores to the table. "\-" can be used for loading from the standard input. \fB\-u\fR (or \fB\-\-user\fR) option overrides the current (real) user to the given one. This option is intended for manipulation with system users' tables (such as apache, postfix, daemon etc.). It can be used only if the current user has root's effective rights. \fB\-l\fR (or \fB\-\-list\fR) option causes the current table is printed to the standard output. \fB\-r\fR (or \fB\-\-remove\fR) option causes the current table (if any) is permanently remove without any warning or confirmation. Use with caution! \fB\-e\fR (or \fB\-\-edit\fR) option causes executing an editor for editing the user table (see below for the information about editor selection). You can edit your incron table now. If the table is changed it stores the modified version. \fB\-t\fR (or \fB\-\-types\fR) option causes the list of supported event types (delimited by commas) is printed to the standard output. This feature is intended for front\-end applications to find out which event types was compiled in. \fB\-d\fR (or \fB\-\-reload\fR) option causes reloading the current table by \fIincrond\fR(8). It is done through "touching" the table (writing into it without modifying it). This feature is intended e.g. for creating watches on newly created files (with already existing rules) or for rearming IN_ONESHOT watches. \fB\-f \fR (or \fB\-\-config=\fR) option specifies another location for the configuration file (/etc/incron.conf is used by default). This feature requires root privileges. There is a few complex algorithm how to determine which editor will be user for editing. If any of the following rule succeeds the appropriate editor is used: 1. EDITOR environment variable 2. VISUAL environment variable 3. configuration value 4. etc/alternatives/editor 5. hard\-wired editor (\fIvim\fR by default) It's not recommended to use graphical editors (such as gVim, KEdit etc.) due to possible problems with connecting to the X server. .SH "SEE ALSO" incrond(8), incrontab(5), incron.conf(5) .SH "AUTHOR" Andreas Altair Redmer (please report bugs to https://github.com/ar-/incron/issues ).

There are two categories of tables: system tables (with root privileges) and user tables (with user privileges). System tables are (by default) located in /etc/incron.d and may have any names. Each system table exists separately inside incron and their watches never collide. Each user has their own table, and commands in any given incrontab will be executed as the user who owns the incrontab. System users (such as apache, postfix, nobody etc.) may have their own incrontab. incrontab files are read when the \fIincrond\fR(8) daemon starts and after any change (incrontab file are being hooked when incrond is running). Blank lines are ignored. The general line format is the following: Where \fIpath\fR is an absolute filesystem path, \fImask\fR is an event mask (in symbolic or numeric form) and \fIcommand\fR is an executable file (or a script) with its arguments. See bellow for event mask symbols. The executable file may be noted as an absolute path or only as the name itself (PATH locations are examined). Please remember that the same path may occur only once per table (otherwise only the first occurrence takes effect and an error message is emitted to the system log). Please not that the * wildcard is allowed to observe a range of files. .SH "EVENT SYMBOLS" These basic event mask symbols are defined: \fBIN_ACCESS\fR File was accessed (read) (*) .br \fBIN_ATTRIB\fR Metadata changed (permissions, timestamps, extended attributes, etc.) (*) .br \fBIN_CLOSE_WRITE\fR File opened for writing was closed (*) .br \fBIN_CLOSE_NOWRITE\fR File not opened for writing was closed (*) .br \fBIN_CREATE\fR File/directory created in watched directory (*) .br \fBIN_DELETE\fR File/directory deleted from watched directory (*) .br \fBIN_DELETE_SELF\fR Watched file/directory was itself deleted .br \fBIN_MODIFY\fR File was modified (*) .br \fBIN_MOVE_SELF\fR Watched file/directory was itself moved .br \fBIN_MOVED_FROM\fR File moved out of watched directory (*) .br \fBIN_MOVED_TO\fR File moved into watched directory (*) .br \fBIN_OPEN\fR File was opened (*) When monitoring a directory, the events marked with an asterisk (*) above can occur for files in the directory, in which case the name field in the returned event data identifies the name of the file within the directory. The \fBIN_ALL_EVENTS\fR symbol is defined as a bit mask of all of the above events. Two additional convenience symbols are \fBIN_MOVE\fR, which is a combination of \fBIN_MOVED_FROM\fR and \fBIN_MOVED_TO\fR, and \fBIN_CLOSE\fR which combines \fBIN_CLOSE_WRITE\fR and \fBIN_CLOSE_NOWRITE\fR. The following further symbols can be specified in the mask: \fBIN_DONT_FOLLOW\fR Don't dereference pathname if it is a symbolic link .br \fBIN_ONESHOT\fR Monitor pathname for only one event .br \fBIN_ONLYDIR\fR Only watch pathname if it is a directory Additionally, there is a symbol which doesn't appear in the inotify symbol set. It is \fBloopable=true\fR. This symbol disables monitoring events until the current one is completely handled (until its child process exits). Also, there is the symbol \fBrecursive=false\fR. This symbol limits the observation on the specified directory and does not include subdirectories. Finally, there is also the symbol \fBdotdirs=true\fR. This symbol will include the hidden directories (where the names starts with a dot) in the observation. .SH "WILDCARDS" The following wildards may be used inside command specification: \fB$$\fR dollar sign .br \fB$@\fR watched filesystem path (see above) .br \fB$#\fR event-related file name .br \fB$%\fR event flags (textually) .br \fB$&\fR event flags (numerically) .SH "EXAMPLE" These are some example rules which can be used in an incrontab file: \fB/tmp IN_ALL_EVENTS abcd $@/$# $%\fR \fB/usr/bin IN_ACCESS,loopable=true abcd $#\fR \fB/home IN_CREATE /usr/local/bin/abcd $#\fR \fB/home IN_CREATE,dotdirs=true /usr/local/bin/abcd $#\fR \fB/home IN_CREATE,recursive=false /usr/local/bin/abcd $#\fR \fB/var/log 12 abcd $@/$#\fR The first line monitors all events on the /tmp directory. When an event occurs it runs a application called 'abcd' with the full path of the file as the first arguments and the event flags as the second one. The second line monitors accesses (readings) on the /usr/bin directory. The application 'abcd' is run as a handler and the appropriate event watch is disabled until the program finishes. The file name (without the directory path) is passed in as an argument. The third example is used for monitoring the /home directory for newly create files or directories (it practically means an event is sent when a new user is added). This event is processed by a program specified by an absolute path. The fourth example is the third example, but it will include hidden directories in the observation. The fifth example is the third example, but it will exclude sub-directories from the observation. And the final line shows how to use numeric event mask instead of textual one.
