It provides a configured number of votes to the quorum subsystem based on a third-party arbitrator's decision. Its primary use is to allow a cluster to sustain more node failures than standard quorum rules allow. It is recommended for clusters with an even number of nodes and highly recommended for 2 node clusters. corosync-qnetd is a daemon running outside of the cluster with the purpose of providing a vote to the corosync-qdevice model net. It's designed to support multiple clusters and be almost configuration and state free. New clusters are handled dynamically and no configuration file exists. It's also able to run as non-root user - which is recommended. Connection between the corosync-qdevice model net client can be optionally configured with TLS client certificate checking. The communication protocol between server and client is designed to be very simple and allow backwards compatibility. Originally both qdevice and qnetd were part of the Corosync codebase (https://github.com/corosync/corosync) but because it's got quite big we decided to split it into it's own sub project.

GNUmakefile has # hooks to force a reconfigure at distribution time to get the value # correct, without penalizing normal development with extra reconfigures. # # .version - present in a checked-out repository and in a distribution # tarball. Usable in dependencies, particularly for files that don't # want to depend on config.h but do want to track version changes. # Delete this file prior to any autoconf run where you want to rebuild # files to pick up a version string change; and leave it stale to # minimize rebuild time after unrelated changes to configure sources. # # It is probably wise to add these two files to .gitignore, so that you # don't accidentally commit either generated file. # # In order to use git archive versions another two files has to be presented: # # .gitarchive-version - present in checked-out repository and git # archive tarball, but not in the distribution tarball.

We must quote the arguments since Win32 CreateProcess() interprets characters like ' ', '\t', '\\', '"' (but not '<' and '>') in a special way: - Space and tab are interpreted as delimiters. They are not treated as delimiters if they are surrounded by double quotes: "...". - Unescaped double quotes are removed from the input. Their only effect is that within double quotes, space and tab are treated like normal characters. - Backslashes not followed by double quotes are not special. - But 2*n+1 backslashes followed by a double quote become n backslashes followed by a double quote (n >= 0): \" -> " \\\" -> \" \\\\\" -> \\" */ #define SHELL_SPECIAL_CHARS "\"\\ \001\002\003\004\005\006\007\010\011\012\013\014\015\016\017\020\021\022\023\024\025\026\027\030\031\032\033\034\035\036\037" #define SHELL_SPACE_CHARS " \001\002\003\004\005\006\007\010\011\012\013\014\015\016\017\020\021\022\023\024\025\026\027\030\031\032\033\034\035\036\037" char ** prepare_spawn (char **argv) { size_t argc; char **new_argv; size_t i; /* Count number of arguments. */ for (argc = 0; argv[argc] != NULL; argc++) ; /* Allocate new argument vector. */ new_argv = XMALLOC (char *, argc + 1); /* Put quoted arguments into the new argument vector. */ for (i = 0; i < argc; i++) { const char *string = argv[i]; if (string[0] == '\0') new_argv[i] = xstrdup ("\"\""); else if (strpbrk (string, SHELL_SPECIAL_CHARS) != NULL) { int quote_around = (strpbrk (string, SHELL_SPACE_CHARS) != NULL); size_t length; unsigned int backslashes; const char *s; char *quoted_string; char *p; length = 0; backslashes = 0; if (quote_around) length++; for (s = string; *s != '\0'; s++) { char c = *s; if (c == '"') length += backslashes + 1; length++; if (c == '\\') backslashes++; else backslashes = 0; } if (quote_around) length += backslashes + 1; quoted_string = XMALLOC (char, length + 1); p = quoted_string; backslashes = 0; if (quote_around) *p++ = '"'; for (s = string; *s != '\0'; s++) { char c = *s; if (c == '"') { unsigned int j; for (j = backslashes + 1; j > 0; j--) *p++ = '\\'; } *p++ = c; if (c == '\\') backslashes++; else backslashes = 0; } if (quote_around) { unsigned int j; for (j = backslashes; j > 0; j--) *p++ = '\\'; *p++ = '"'; } *p = '\0'; new_argv[i] = quoted_string; } else new_argv[i] = (char *) string; } new_argv[argc] = NULL; return new_argv; } EOF ;; esac cat <<"EOF" void lt_dump_script (FILE* f) { EOF func_emit_wrapper yes | $SED -n -e ' s/^\(.\{79\}\)\(..*\)/\1\ \2/ h s/\([\\"]\)/\\\1/g s/$/\\n/ s/\([^\n]*\).*/ fputs ("\1", f);/p g D' cat <<"EOF" } EOF } # end: func_emit_cwrapperexe_src # func_win32_import_lib_p ARG # True if ARG is an import lib, as indicated by $file_magic_cmd func_win32_import_lib_p () { $opt_debug case `eval $file_magic_cmd \"\$1\" 2>/dev/null | $SED -e 10q` in *import*) : ;; *) false ;; esac } # func_mode_link arg... func_mode_link () { $opt_debug case $host in *-*-cygwin* | *-*-mingw* | *-*-pw32* | *-*-os2* | *-cegcc*) # It is impossible to link a dll without this setting, and # we shouldn't force the makefile maintainer to figure out # which system we are compiling for in order to pass an extra # flag for every libtool invocation. # allow_undefined=no # FIXME: Unfortunately, there are problems with the above when trying # to make a dll which has undefined symbols, in which case not # even a static library is built.

It provides a configured number of votes to the quorum subsystem based on a third-party arbitrator's decision. Its primary use is to allow a cluster to sustain more node failures than standard quorum rules allow. It is recommended for clusters with an even number of nodes and highly recommended for 2 node clusters. .SH OPTIONS .TP .B -d Forcefully turn on debug information without the need to change corosync.conf. .TP .B -f Do not daemonize, run in the foreground. .TP .B -h Show short help text .TP .B -S Set advanced settings described in its own section below. This option shouldn't be generally used because most of the options are not safe to change. .SH CONFIGURATION .B corosync-qdevice reads its configuration from corosync.conf file. The main configuration is within .B quorum.device sub-key. Each model also has its own configuration within a similarly named sub-key. .TP .B model Specifies the model to be used. This parameter is required. .B corosync-qdevice is modular and is able to support multiple different models. The model basically defines what type of arbitrator is used. Currently only .I net is supported. .TP .B timeout Specifies how often .B corosync-qdevice should call the votequorum_poll function. It is also used by the .I net model to adjust its hearbeat timeout. It is recommended that you don't change this value. Default is .IR 10000 . .TP .B sync_timeout Specifies how often .B corosync-qdevice should call the votequorum_poll function during a sync phase. It is recommended that you don't change this value. Default is .IR 30000 . .TP .B votes The number of votes provided to the cluster by qdevice. Default is (number_of_nodes - 1) or generally sum(votes_per_node) - 1. .PP .B quorum.device.heuristics subkey holds the configuration of the heuristics. Heuristics are set of commands executed locally on startup, cluster membership change, successful connect to .B corosync-qnetd and optionally also at regular times. Commands are executed in parallel. When all commands finish successfully (their return error code is zero) on time, heuristics have passed, otherwise they have failed. The heuristics result is sent to .B corosync-qnetd and there it's used in calculations to determine which partition should be quorate. .TP .B timeout Specifies maximum time in milliseconds how long .B corosync-qdevice waits till the heuristics commands finish. If some command doesn't finish before the timeout, it's killed and heuristics fail. This timeout is used for heuristics executed at regular times. Default value is half of the .BR quorum.device.timeout ", so" .IR 5000 . .TP .B sync_timeout Similar to quorum.device.heuristics.timeout but used during membership changes. Default value is half of the .BR quorum.device.sync_timeout ", so" .IR 15000 . .TP .B interval Specifies interval between two regular heuristics execution. Default value is 3 * .BR quorum.device.timeout ", so" .IR 30000 . .TP .B mode Can be one of .IR on ", " sync " or " off and specifies mode of operation of heuristics. Default is .IR off , which means heuristics are disabled. When .I sync is set, heuristics are executed only during startup, membership change and when connection to .B corosync-qnetd is established. When heuristics should be running also on regular basis, this option should be set to .I on value. .TP .B exec_NAME defines executables. .I NAME can be arbitrary valid cmap key name string and it has no special meaning. The value of this variable must contain a command to execute. The value is parsed (split) into arguments similarly as Bourne shell would do. Quoting is possible by using backslash and double quotes. .PP .B quorum.device.net subkey holds the configuration for .B model .IR net . .TP .B tls Can be one of .IR on ", " off " or " required and specifies if tls should be used. .I on means a connection with TLS is attempted first, but if the server doesn't advertise TLS support then non-TLS will be used. .I off is used then TLS is not required and it's then not even tried. This mode is the only one which doesn't need a properly initialized NSS database. .I required means TLS is required and if the server doesn't support TLS, qdevice will exit with error message. Default is .IR on . .TP .B host Specifies the IP address or host name of the qnetd server to be used. This parameter is required. .TP .B port Specifies TCP port of qnetd server. Default is .IR 5403 . .TP .B algorithm Decision algorithm. Can be one of the .I ffsplit or .IR lms . (actually there are also .I test and .IR 2nodelms , both of which are mainly for developers and shouldn't be used for production clusters). For a description of what each algorithm means and how the algorithms differ see their individual sections. Default value is .IR ffsplit . .TP .B tie_breaker can be one of .IR lowest ", " highest or valid_node_id (number) values. It's used as a fallback if qdevice has to decide between two or more equal partitions. .I lowest means the partition with the lowest node id is chosen. .I highest means the partition with highest node id is chosen. And valid_node_id means that the partition containing the node with the given node id is chosen. Default is .IR lowest . .TP .B connect_timeout Timeout when .B corosync-qdevice is trying to connect to .B corosync-qnetd host. Default is 0.8 * .BR quorum.sync_timeout . .TP .B force_ip_version can be one of .I 0|4|6 and forces the software to use the given IP version. .I 0 (default value) means IPv6 is preferred and IPv4 should be used as a fallback. .PP Logging configuration is within the .B logging directive. .B corosync-qdevice parses and supports most of the options with exception of .BR to_logfile ", " logfile and .BR logfile_priority . The .B logger_subsys sub-directive can be also used if .B subsys is set to .IR QDEVICE . .PP For .B corosync-qdevice to work correctly, the .B nodelist directive has to be used and properly configured. Also the .I net model requires that .B totem.cluster_name option is set. .SH MODEL NET TLS CONFIGURATION For .B model .I net to work using TLS, it's necessary to create the NSS database, import Qnetd CA certificate, and get/distribute a valid client certificate. If pcs is used (recommended) the following steps are not needed because pcs does them automatically. .B corosync-qdevice-net-certutil is the tool to perform required actions semi-automatically. Please consult the help output of it and its man page. For a first time configuration it may make sense to start with the .B -Q option. If TLS is not required just edit corosync.conf file and set .B quorum.device.net.tls to .IR off . Depending on configuration of NSS (stored in nss.config file usually in /etc/crypto-policies/back-ends/ directory) disabled ciphers or too short keys may be rejected. Proper solution is to regenerate NSS databases for both .B corosync-qnetd and .B corosync-qdevice daemons. As a quick workaround it's also possible to set environment variable .I NSS_IGNORE_SYSTEM_POLICY=1 before running .B corosync-qdevice daemon. When NSS is updated it may also be needed to upgrade database into new format. There is no consensus on recommended way, but following command seems to work just fine (if qdevice sysconfdir is set to /etc) .nf # certutil -N -d /etc/corosync/qdevice/net/nssdb -f /etc/corosync/qdevice/net/nssdb/pwdfile.txt .fi .SH MODEL NET ALGORITHMS Algorithms are used to change behavior of how .B corosync-qnetd provides votes to a given node/partition. Currently there are two algorithms supported. .TP .B ffsplit This one makes sense only for clusters with an even number of nodes. It provides exactly one vote to the partition with the highest number of active nodes. If there are two exactly similar partitions, it provides its vote to the partition with higher score. The score is computed as (number_of_connected_nodes + number_of_connected_nodes_with_passed_heuristics - number_of_connected_nodes_with_failed_heuristics) If the scores are equal, the vote is provided to partition with the most clients connected to the qnetd server. If this number is also equal, then the tie_breaker is used. It is able to transition its vote if the currently active partition becomes partitioned and a non-active partition still has at least 50% of the active nodes. Because of this, a vote is not provided if the qnetd connection is not active. To use this algorithm it's required to set the number of votes per node to 1 (default) and the qdevice number of votes has to be also 1. This is achieved by setting .B quorum.device.votes key in corosync.conf file to 1. .TP .B lms Last-man-standing. If the node is the only one left in the cluster that can see the qnetd server then we return a vote. If more than one node can see the qnetd server but some nodes can't see each other then the cluster is divided up into 'partitions' based on their ring_id and this algorithm returns a vote to the partition with highest heuristics score (computed the same way as for the .B ffsplit algorithm), or if there is more than 1 partition with equal scores, the largest active partition or, if there is more than 1 equal partition, the partition that contains the tie_breaker node (lowest, highest, etc). For LMS to work, the number of qdevice votes has to be set to default (so just delete .B quorum.device.votes key from corosync.conf). .SH ADVANCED SETTINGS Set by using .B -S option. The default value is shown in parentheses) Options beginning with .B net_ prefix are specific to .B model .IR net . .TP .B lock_file Lock file location.

The default directory for the database is /etc/corosync/qnetd. This directory must be writeable by the current user. The QNetd CA certificate is also exported into the file /etc/corosync/qnetd/nssdb/qnetd-cacert.crt. .TP .B -s Sign the cluster certificate.

The certificate request is exported into /etc/corosync/qdevice/net/qdevice-net-node.crq. It is necessary to pass the cluster name using the .B -n parameter. The cluster name has to match the one defined in /etc/corosync/corosync.conf. .TP .B -M Import a signed certificate and export a certificate with private key into pk12 file. .TP .B -Q Use ssh/scp to properly set both .B corosync-qnetd and .B corosync-qdevice certificates on all nodes. It's highly recommended that you use an ssh agent, or ssh/scp will keep asking for a password - roughly 8 times the number of nodes. .TP .B -c File with certificate to load. .TP .B -n Name of the cluster. .SH SEE ALSO .BR corosync-qnetd (8) .BR corosync-qdevice (8) .SH AUTHOR Jan Friesse .PP corosync-qdevice-3.0.0/man/corosync-qdevice-tool.80000664000175000017500000001064213231627645017022 00000000000000.\"/* .\" * Copyright (C) 2016-2017 Red Hat, Inc. .\" * .\" * All rights reserved. .\" * .\" * Author: Jan Friesse .\" * .\" * This software licensed under BSD license, the text of which follows: .\" * .\" * Redistribution and use in source and binary forms, with or without .\" * modification, are permitted provided that the following conditions are met: .\" * .\" * - Redistributions of source code must retain the above copyright notice, .\" * this list of conditions and the following disclaimer. .\" * - Redistributions in binary form must reproduce the above copyright notice, .\" * this list of conditions and the following disclaimer in the documentation .\" * and/or other materials provided with the distribution. .\" * - Neither the name of Red Hat, Inc. nor the names of its .\" * contributors may be used to endorse or promote products derived from this .\" * software without specific prior written permission. .\" * .\" * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" .\" * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE .\" * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE .\" * ARE DISCLAIMED.

Its main purpose is to show important information about the current internal state of .B corosync-qdevice. .SH OPTIONS .TP .B -H Properly shutdown the .B corosync-qdevice process .TP .B -h Display a short usage text .TP .B -s Display the status of the .B corosync-qdevice process. The output is described in its own section below. .TP .B -v Display more verbose output for the .B -s option. .TP .B -p Path to the .B corosync-qdevice communication socket. .SH STATUS COMMAND OUTPUT .nf Qdevice information ------------------- Model: Net Node ID: 1 HB interval: 10000ms Sync HB interval: 30000ms Configured node list: 0 Node ID = 1 Heuristics: Enabled Ring ID: 1.a00000000021b48 Membership node list: 1 Quorate: Yes Quorum node list: 0 Node ID = 1, State = member Expected votes: 2 Last poll call: 2016-06-24T17:05:20 (cast vote) Qdevice-net information ---------------------- Cluster name: Cluster QNetd host: localhost:5403 Connect timeout: 8000ms HB interval: 8000ms VQ vote timer interval: 5000ms TLS: Supported Algorithm: Fifty-Fifty split Tie-breaker: Node with lowest node ID Poll timer running: Yes (cast vote) State: Connected Heuristics result: Pass (regular: Pass, membership: Fail, connect: Fail) TLS active: Yes (client certificate sent) Connected since: 2016-06-24T17:02:35 Echo reply received: 2016-06-24T17:05:15 .fi The output is split into a generic qdevice section and a model specific section. Most of the items are just taken from corosync.conf file. It's helpful to note that the .I Membership node list is the membership list of the current node and should match the quorum node list. .I Last poll call is the timestamp (in iso format) of the last call to the votequorum_qdevice_poll function. For model net, it's good to check the .I Poll timer running state. Internally, model net supports 3 states. Not voting (when .I Poll timer running is No, which means .B corosync-qdevice is waiting for .B corosync-qnetd to reply), voting (without cast vote, it means that the .B corosync-qnetd algorithm decides that the current node shouldn't get a vote) and voting (with cast vote). .SH SEE ALSO .BR corosync-qnetd (8) .BR corosync-qdevice (8) .SH AUTHOR Jan Friesse .PP corosync-qdevice-3.0.0/man/Makefile.in0000664000175000017500000004574613404212216014545 00000000000000# Makefile.in generated by automake 1.13.4 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2013 Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ # Copyright (c) 2004 MontaVista Software, Inc. # Copyright (c) 2009 - 2018 Red Hat, Inc. # # Authors: Jan Friesse (jfriesse@redhat.com) # Steven Dake (sdake@redhat.com) # Fabio M.

It's designed to support multiple clusters and be almost configuration and state free. New clusters are handled dynamically and no configuration file exists. It's also able to run as non-root user - which is recommended. Connection between the .B corosync-qdevice model net client can be optionally configured with TLS client certificate checking. The communication protocol between server and client is designed to be very simple and allow backwards compatibility. .SH OPTIONS .TP .B -4 and its counterpart .B -6 are used to force IPv4 or IPv6 communication. The default is to listen on both address families. .TP .B -d Turn on debug logging. By default the messages sent to syslog are purely operational, this option sends additional debug messages. For even more detail use the .B -d parameter twice. .TP .B -f Do not daemonize, run in the foreground. .TP .B -h Show short help text .TP .B -v Show version and supported communication protocol messages/options. .TP .B -l IP address to listen on. By default the daemon listens on all addresses (wildcard). .TP .B -p TCP port to listen on. Default port is 5403. .TP .B -s Determines if TLS should be used and can be one of .I on/off/required (the default is .I on ). .I on means TLS is enabled but the client is not required to start TLS, .I off means TLS is completely disabled, and .I required means TLS is required. .I on and .I required require the NSS database to be properly initialized by running the .B corosync-qnetd-certutil command. .TP .B -c can be set to .I on/off. This option only makes sense if TLS is enabled. When .B -c is .I on a client is required to send its client certificate (default). .TP .B -m Maximum simultaneous clients. The default is 0 which means no limit. .TP .B -S Set advanced settings described in its own section below. This option shouldn't be generally used because most of the options are not safe to change. .SH UNPRIVILEGED USER CONFIGURATION It's generally recommended to run .B corosync-qnetd as a non root user. If you get a package from a distribution its highly possible that the packager has done all the hard work for you. If the installation is performed from source code, a few steps have to be taken. First it's necessary to create an unprivileged user/group. The following commands can be used (executed as root): .nf # groupadd -r coroqnetd # useradd -r -g coroqnetd -d / -s /sbin/nologin -c "User for corosync-qnetd" coroqnetd .fi The next step is to set the correct owner and group on /etc/corosync/qnetd and /var/run/corosync-qnetd directories. .nf # chown -R coroqnetd:coroqnetd /etc/corosync/qnetd /var/run/corosync-qnetd .fi Some systems have the /var/run directory on a tmpfs file system which gets discarded after a reboot. The solution is to use an initscript or systemd unit, because both of them takes care of the /var/run/corosync-qnetd creation and sets the correct owner and permissions. The last step is to make sure .B corosync-qnetd is really executed as an unprivileged user. For initscript systems it's enough to set the line COROSYNC_QNETD_RUNAS in /etc/(sysconfig|default)/corosync-qnetd file. If the file is not already installed then use the one provided in the corosync source code (init/corosync-qnetd.sysconfig.example). For systemd, overwrite/copy the corosync-qnetd.service unit file and uncomment/change the "User=" directive. .SH TLS CONFIGURATION For TLS to work its necessary to create the NSS database. If pcs is used then the following steps are not needed because pcs does them automatically. .B corosync-qnetd-certutil is the tool to perform required actions. Just run: .nf # corosync-qnetd-certutil -i .fi If TLS is not required then simply edit /etc/(sysconfig|default)/corosync-qnetd or systemd unit file and add the parameter .B -s .I off in the proper place. Depending on configuration of NSS (stored in nss.config file usually in /etc/crypto-policies/back-ends/ directory) disabled ciphers or too short keys may be rejected. Proper solution is to regenerate NSS databases for both .B corosync-qnetd and .B corosync-qdevice daemons. As a quick workaround it's also possible to set environment variable .I NSS_IGNORE_SYSTEM_POLICY=1 before running .B corosync-qnetd daemon. When NSS is updated it may also be needed to upgrade database into new format. There is no consensus on recommended way, but following command seems to work just fine (if qnetd sysconfdir is set to /etc) .nf # certutil -N -d /etc/corosync/qnetd/nssdb -f /etc/corosync/qnetd/nssdb/pwdfile.txt .fi .SH ADVANCED SETTINGS Set by the .B -S option. The default value is shown in parentheses. .TP .B listen_backlog Parameter passed to the listen syscall on the network socket. (10) .TP .B max_client_send_buffers Maximum number of send buffers for one client. (32) .TP .B max_client_send_size Maximum size of one send buffer (message) to be sent to a client. (32768) .TP .B max_client_receive_size Maximum size of the receive buffer for a client message (maximum allowed message size received by client). (32768) .TP .B nss_db_dir NSS database directory. (/etc/corosync/qnetd/nssdb) .TP .B cert_nickname NSS nickname of qnetd server certificate. (QNetd Cert) .TP .B heartbeat_interval_min Minimum heartbeat timeout accepted by server in ms. (1000) .TP .B heartbeat_interval_max Maximum heartbeat timeout accepted by server in ms. (120000) .TP .B dpd_enabled Dead peer detection enabled. (on) .TP .B dpd_interval How often the DPD algorithm detects dead peers in ms. (10000) .TP .B lock_file Lock file location. (/var/run/corosync-qnetd/corosync-qnetd.pid) .TP .B local_socket_file Internal IPC socket file location. (/var/run/corosync-qnetd/corosync-qnetd.sock) .TP .B local_socket_backlog Parameter passed to listen syscall on the local socket. (10) .TP .B ipc_max_clients Maximum allowed simultaneous IPC clients. (10) .TP .B ipc_max_receive_size Maximum size of a message received by IPC client. (4096) .TP .B ipc_max_send_size Maximum size of a message sent to an IPC client.

This is usually not a problem, but when containers are used it may result to killing improper instance when issued on host. Solution is to always use pidfile. Also try to use LSB complaint status codes. Reviewed-by: Christine Caulfield 2018-11-07 Jan Friesse configure: move to AC_COMPILE_IFELSE from AC_PREPROC_IFELSE which is strongly discouraged. Our detection system was very weak and recent versions of clang did show that PREPROC_IFELFE (cpp) would enable warning options that the compiler does not support (clang). Use a full compilation test to detect what works and what doesn't. Based on knet patch 88491f27375a9e8aceb946853a1abf4d23ebb8f3. Reviewed-by: Fabio M. Di Nitto 2018-09-03 Jan Friesse git-version-gen: Fail on UNKNOWN version Reviewed-by: Christine Caulfield build: Support for git archive stored tags Attempt to solve problem with git archive generated tarballs (used for example by github when release is downloaded) which are no longer git tree and (in contrast to officially released tarballs) also doesn't contain .tarball-version file so git-version-gen script simply cannot obtain valid version info. Solution is based on using gitattributes which is instructs git to replace string in the .gitarchivever file by known ref names. git-version-gen is enhanced to support this file and tries to parse any string which looks like "tag: v[0-9]+.[0-9]+.[0-9]". If such string is found it's used as a version. This file is used as a last attempt and other methods (.tarball-version, git abbrev) have precedence. Based on idea stated by Jan Pokorný .

This was incorrect because with exception of local ipc close all other disconnect reasons are errors. Solution is to return proper error code. Also instead of exit right after qdevice_model_run it's better to store result value, try clean resources and use stored value to return correct exit code. 2018-08-22 Jan Friesse build: Remove WITH_LIST WITH_LIST is replaced in favor of bcond generator. spec: Autogenerate bcond options based on config Inspired by kronosnet spec file generator. 2018-08-21 Jan Friesse spec: add exlicit docdir OpenSUSE does not ship docs in the normal dir and their rpm macro does not appear to set it for us.

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say).

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.
