By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, 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 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 - - 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) - - 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., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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.

If at some point `config.cache' -contains results you don't want to keep, you may remove or edit it. - - The file `configure.in' is used to create `configure' by a program -called `autoconf'. You only need `configure.in' 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. You can give `configure' -initial values for variables by setting them in the environment. Using -a Bourne-compatible shell, you can do that on the command line like -this: - CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure - -Or on systems that have the `env' program, you can do it like this: - env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure - -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 supports 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' can not figure out -automatically, but needs to determine by the type of host the package -will run on. Usually `configure' can figure that out, but if it prints -a message saying it can not guess the host type, give it the -`--host=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name with three fields: - CPU-COMPANY-SYSTEM - -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 host type. - - If you are building compiler tools for cross-compiling, you can also -use the `--target=TYPE' option to select the type of system they will -produce code for and the `--build=TYPE' option to select the type of -system on which you are compiling the package. - -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. - -Operation Controls -================== - - `configure' recognizes the following options to control how it -operates. - -`--cache-file=FILE' - Use and save the results of the tests in FILE instead of - `./config.cache'. Set FILE to `/dev/null' to disable caching, for - debugging `configure'. - -`--help' - Print a summary of the options to `configure', and exit. - -`--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.

On the receivers side rsyncd can be - configured to also change the uid/gid of the file. Lsyncd is especially - useful to sync data from a secure area to a not-so-secure area (e.g. as a - one way connection to allow employees to publish their files to a public - accessible web server). - -WHEN NOT TO USE: - - * File with active file handles (e.g. database files) - * Directories where many changes occur (like mail or news servers) - - In these cases e.g. DRBD (see http://www.drbd.org/) might be better - for you. - -COMPARISONS: - - Lsyncd vs. DRBD: - - DRBD operates on block device level.

Lsyncd on the other hand - - * does not require you to change block devices and/or mount points. - * allows you to change uid/gid of the transferred files. - * separates the receiver through the one-way nature of rsync. - - However when using lsyncd a file change can possibly result in a full file - transfer (at least for binary files) and is therefore unsuitable for - databases. Also a directory rename will result in transferring the whole - directory. - - Lsyncd vs. incron: - - Incron does not (yet) support recursive directory watching making it - unsuitable for described needs (http://inotify.aiken.cz/?section=incron&page=about&lang=en). - In fact a different approach would have been to extent incron. However, we - decided to stick to the NIH principle (Not Invented Here) :-), because extending - the C++ solution seemed to tedious. - - Lsyncd vs. FUSE: - - This is another interesting idea is to write a daemon that provides a - shadow file system through fuse. When accessing a file the data is synced - to local file as well as the remote file. Whit this approach inotify could - be replaced. GlusterFS does exactly this and more (see http://www.gluster.org). - BindFS (see http://www.cs.helsinki.fi/u/partel/bindfs/) does this for local - mirroring. We discarded this idea because it would affect performance of - normal operations in a negative way. - - Lsyncd vs. cron: - - If you find a solution using cron to call rsync over the whole directory - tree periodically after every 'X' hours/minutes/seconds more satisfying - than lsyncd, please go for it *sulking*. We don't like it! - -LSYNCD USAGE EXAMPLES: - - /usr/sbin/lsyncd /var/www/ remotehost::wwwshare/ - - This watches and rsycn's the local directory /var/www/ with all - subdirectories and transfers them to 'remotehost' using the rsync-share - 'wwwshare'. - - /usr/sbin/lsyncd --nodaemon --exclude-from /etc/lsycnd/exclude \ - /var/www/ remotehost::wwwshare/ - - This will also rsync/watch '/var/www', but it excludes files and directories - from '/etc/lsycnd/exclude'. Additionally this example lsyncd will not fork, - and log to stdout/stderr instead. - - /usr/sbin/lsyncd %userwww remotehost::wwwshare/foobar/ - - This special target will scan through all directories in /home and syncs all - www subdirectories of the users to wwwshare in the subdirectory foobar. - The user peter having his local data in /home/peter/www/ will have it - rsynced to ::wwwshare/foobar/peter/. - -LIMITATIONS: - Be aware that the kernel limits the number of watches. You can see the limit - in - /proc/sys/fs/inotify/max_user_watches - - which is usually set to 8192. This means lsyncd cannot watch more than 8192 - directories unless you change the kernel setting. Lsyncd itself has no - limits. - - Because Axel is lazy the maximum possible size a filename is 8192. If you - need more, change MAX_PATH in lsyncd.c. Or send me patches that introduce - dynamic memory usage. - -SOURCE DOCUMENTATION: - - The only file of interest is 'lsyncd.c' which includes comments. - Everything else in the tarball is packaging bushwa. - -DISCLAIMER: - - Besides the usual disclaimer in the license, we want to specifically EMPHASIZE - that NEITHER the authors NOR any organization the authors are associated with - can and will hold responsible for data-loss caused by possible malfunctions - of lsyncd. Especially if you run it with root privileges ;-) (we ourselves - run lsyncd as www-data). - -FEEDBACK: - - Please send praises and feedback to: axel.kittenberger@univie.ac.at diff --git a/TODO b/TODO deleted file mode 100644 index 1850cdc..0000000 --- a/TODO +++ /dev/null @@ -1,9 +0,0 @@ -* React on signal HUP resync and rewatch everything. -* Workaround the kernel watches limit by opening another inotify - instance when needed. -* React on inotify OVERFLOW messages in resyncing everything, something might - have been missed. -* Allow more complicated exclusion masks. -* Do not call rsync at all if a file was edited that falls under the exclusion - mask (currently it is called, and rsync drops it). -* improve config.h.in generation diff --git a/autogen.sh b/autogen.sh index 4a810ce..01c075c 100755 --- a/autogen.sh +++ b/autogen.sh @@ -1,11 +1,9 @@ -#!/bin/bash -# simplistic script to run after checkout +#!/bin/sh -# In case of explicit having a 1.7 version use that (for systems having multiple automake versions installed) -ACLOCAL=`which aclocal-1.7 || echo aclocal` -AUTOMAKE=`which automake-1.7 || echo automake` +echo "Generating configure files... may take a while." -$ACLOCAL && \ -autoheader && \ -autoconf && \ -$AUTOMAKE -a -c +autoreconf --install --force && \ + echo "Preparing was successful if there was no error messages above." && \ + echo "Now type:" && \ + echo " ./configure && make" && \ + echo "Run './configure --help' for more information" diff --git a/config.guess b/config.guess deleted file mode 100755 index 396482d..0000000 --- a/config.guess +++ /dev/null @@ -1,1500 +0,0 @@ -#! /bin/sh -# Attempt to guess a canonical system name. -# Copyright (C) 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, -# 2000, 2001, 2002, 2003, 2004, 2005, 2006 Free Software Foundation, -# Inc. - -timestamp='2006-07-02' - -# This file 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.

A lsyncd configuration file has an XML grammar. That means tags have to be closed with a / and the such. Following explanations will be provided with an examples. - The config file must start with a root node. A "version" parameter has to be present which specifies the lsyncd version of the config file format. Currently this is 1. - <lsyncd version="1"> - - - SETTINGS - Next is optionally a node. It controls lsyncd global settings. All settings are optional. - <settings> - - If a node is present all debug messages will be logged. Default is a normal verbosity. - <debug/> - - If specified by the "value" parameter is greater than zero, lsyncd waits this amount of seconds between an event and calling the binary. All events for a directory in this timeframe will be aggregated to one call. If delay is 0 changes will be handlet immediatly. Default is 5 seconds. - <delay/> - - If a node is present only error messages will be logged. Default is a normal verbosity. - <scarce/> - - If a node is present lsyncd will continue even if the startup sync fails. Default is being not stubborn. - <stubborn/> - - If a node is present lsyncd will not detach and log to stdout/stderr. Default is to detach as daemon. - <no-daemon/> - - If a node is present lsyncd will not initiate the recursive rsync call on startup. Not adviced, know what you are doing if using this. - <no-startup/> - - If a node is present lsyncd will not call any actions (rsync) for test purposes. Default is not to run dry. - <dry-run/> - - With an entry an exclusion file can be specified with a "filename" parameter. This will be passed to rsync and follows rsyncs grammar for exclude files. Default is not to pass an exlude file to rsync. - <exclude-from filename="/etc/lsyncd.exclude"/> - - With a node to location of the logfile can be changed. Default is /var/log/lsyncd. Take care that the user which lsyncd is running with can write to this file. - <logfile filename="/var/log/lsyncd"/> - - A node specifies the binary lsyncd will call to sync stuff. Usually you want this to be rsync. Default is /usr/bin/rsync. - <binary filename="/usr/bin/rsync"/> - - If a node is present lsyncd will write its pid there. Default is not to write a pidfile. - <pidfile filename="/var/run/lsyncd.pid"/> - - With a node you can control the arguments lsyncd will call the <binary> (rsync) with. Each child node will specify one argument. <option> specifies a literal argument. Only %r will be replaced with 'r' when rsycnd is supposed to work recursive (on startup of lsyncd) or 'd' on normal operations. <exclude-file> will be replaced with if an <exclude-from> file is specified. <source> will be replaced the source directory to sync from. <destination> will be replace to the target to sync to. Default arguments are . - <callopts> - With a node you can control the inotify events lsyncd will register to. Each event is configured by a <event> child node and its attribute 'id'. The following events may be registered: ACCESS,ATTRIB,CLOSE_WRITE,CLOSE_NOWRITE,CREATE,DELETE,DELETE_SELF,MODIFY,MOVE_SELF,MOVED_FROM,MOVED_TO,OPEN. If the inotify node is omitted the following events are registered by default: IN_ATTRIB,IN_CLOSE_WRITE,IN_CREATE,IN_DELETE,IN_DELETE_SELF,IN_MOVED_FROM,IN_MOVED_TO,IN_DONT_FOLLOW,IN_ONLYDIR. - <inotify> - <event id="MOVED_TO"/> - <event id="DELETE"/> - </inotify> - - <option text="-lts%r"/> - <option text="--delete"/> - <exclude-file/> - <source/> - <destination/> - </callopts> - End of (optional) settings section. - </settings> - - - - DIRECTORIES -+ With nodes arbitrarily many sources to be watched can be specified. Within a <directory> entry you can again specify a , , or a node which will override global settings just for this source. See SETTINGS for details on this options. -+ The mandatory node specifies with the paramater "path" the directory to watch and sync. (once in a while something is mandatory. Also at least one node has to specified where to sync to.
