GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, 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. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; 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.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.
<signature of Ty Coon>, 1 April 1990
Ty Coon, President of Vice
That's all there is to it!

# How to build from source
## Requirements
### Common requirements
In order to build csync, you need to install several components:
- A C compiler
- [CMake](http://www.cmake.org) >= 2.6.0.
- [check](http://check.sourceforge.net) >= 0.9.5
- [sqlite3](http://www.sqlite.org) >= 3.4
- [libneon](http://www.webdav.org/neon/) >= 0.29.0
optional:
- [libsmbclient](http://www.samba.org) >= 3.5
- [libssh](http://www.libssh.org) >= 0.5
sqlite3 is a runtime requirement. libsmbclient is needed for
the smb plugin, libssh for the sftp plugin. libneon is required for the
ownCloud plugin.
Note that these version numbers are version we know works correctly. If you
build and run csync successfully with an older version, please let us know.
## Building
First, you need to configure the compilation, using CMake. Go inside the
`build` dir. Create it if it doesn't exist.
GNU/Linux and MacOS X:
cmake -DCMAKE_BUILD_TYPE=Debug ..
make
### CMake standard options
Here is a list of the most interesting options provided out of the box by CMake.
- CMAKE_BUILD_TYPE: The type of build (can be Debug Release MinSizeRel RelWithDebInfo)
- CMAKE_INSTALL_PREFIX: The prefix to use when running make install (Default to
/usr/local on GNU/Linux and MacOS X)
- CMAKE_C_COMPILER: The path to the C compiler
- CMAKE_CXX_COMPILER: The path to the C++ compiler
### CMake options defined for csync
Options are defined in the following files:
- DefineOptions.cmake
They can be changed with the -D option:
`cmake -DCMAKE_BUILD_TYPE=Debug -DWITH_LOG4C=OFF ..`
### Browsing/editing CMake options
In addition to passing options on the command line, you can browse and edit
CMake options using `cmakesetup` (Windows) or `ccmake` (GNU/Linux and MacOS X).
- Go to the build dir
- On Windows: run `cmakesetup`
- On GNU/Linux and MacOS X: run `ccmake ..`
## Installing
Befor installing you can run the tests if everything is working:
make test
If you want to install csync after compilation run:
make install
## Running
The csync binary can be found in the `build/client` directory.

WHAT IS CSYNC?
==============
csync is a lightweight utility to synchronize files between two directories on
a system or between multiple systems.
It synchronizes bidirectionally and allows the user to keep two copies of files
and directories in sync. csync uses widely adopted protocols, such as smb or
sftp, so that there is no need for a server component. It is a user-level
program which means you don’t need to be a superuser or administrator.
CONTRIBUTIONS
=============
If you want to contribute to the development of the software then please join
the mailing list. Patches are accepted preferebly created with git and we are
always glad to receive feedback or suggestions to the address
csync-devel@csync.org.
More information on the various mailing lists can be found at
http://www.csync.org/communication/.
You can also get the sourcecode straight from the git repository - see
http://git.csync.org/
DOCUMENTATION
=============
As a user you can find a userguide which is shipped with this package or is
available at the website. For developers there is doxygen documentation and
comments in the source code itself. See

CSYNC User Guide
================
Andreas Schneider <asn@cryptomilk.org>
:Author Initials: ADS
csync is a lightweight utility to synchronize files between two directories
on a system or between multiple systems.
It synchronizes bidirectionally and allows the user to keep two copies of files
and directories in sync. csync uses widely adopted protocols, such as smb or
sftp, so that there is no need for a server component. It is a user-level
program which means you don't need to be a superuser or administrator.
Together with a Pluggable Authentication Module (PAM), the intent is to provide
Roaming Home Directories for Linux (see <<X80, The PAM Module>>).
Introduction
------------
It is often the case that we have multiple copies (called replicas) of a
filesystem or part of a filesystem (for example on a notebook and desktop
computer). Changes to each replica are often made independently, and as a
result, they do not contain the same information. In that case, a file
synchronizer is used to make them consistent again, without losing any
information.
The goal is to detect conflicting updates (files which have been modified) and
propagate non-conflicting updates to each replica. If there are no conflicts
left, we are done, and the replicas are identical. To resolve or handle
conflicts there are several algorithms available. They will be discussed
one of the following sections.
Basics
------
This section describes some basics of file synchronization.
Paths
~~~~~
A path normally refers to a point which contains a set of files which should be
synchronized. It is specified relative to the root of the replica locally, but
has to be absolute if you use a protocol. The path is just a sequence of names
separated by '/'.
NOTE: The path separator is always a forward slash '/', even for Windows.
csync always uses the absolute path on remote replicas. This could
'sftp://gladiac:secret@myserver/home/gladiac' for sftp.
What is an update?
~~~~~~~~~~~~~~~~~~
The contents of a path could be a file, a directory or a symbolic link
(symbolic links are not supported yet). To be more precise, if the path refers
to:
- a regular file: the contents of the file are the byte stream and the
metadata of the file.
- a directory: then the content is the metadata of the directory.
- a symbolic link: the content is the named file the link points to.
csync keeps a record of each path which has been successfully synchronized. The
path gets compared with the record and if it has changed since the last
synchronization, we have an update. This is done by comparing the modification
or change (modification time of the metadata) time. This is the way how updates
are detected.
What is a conflict?
~~~~~~~~~~~~~~~~~~~
A path is conflicting if it fulfills the following conditions:
1. it has been updated in one replica,
2. it or any of its descendants has been updated on the other replica too, and
3. its contents in are not identical.
File Synchronization
--------------------
The primary goal of the file synchronizer is correctness. It may change
scattered or large parts of the filesystem. Since this in mostly not monitored
by the user, and the file synchronizer is in a position to harm the system,
csync must be safe, even in the case of unexpected errors (e.g. disk full).
What was done to make csync safe is described in the following sections.
One problem concerning correctness is the handling of conflicts. Each file
synchronizer tries to propagate conflicting changes to the other replica. At
the end both replicas should be identical. There are different strategies to
fulfill these goals.
csync is a three-phase file synchronizer. The decision for this design was that
user interaction should be possible and it should be easy to understand the
process. The three phases are update detection, reconciliation and propagation.
These will be described in the following sections.
Update detection
~~~~~~~~~~~~~~~~
There are different strategies for update detection. csync uses a state-based
modtime-inode update detector. This means it uses the modification time to
detect updates. It doesn't require many resources. A record of each file is
stored in a database (called statedb) and compared with the current
modification time during update detection. If the file has changed since the
last synchronization an instruction is set to evaluate it during the
reconciliation phase. If we don't have a record for a file we investigate, it
is marked as new.
It can be difficult to detect renaming of files. This problem is also solved
by the record we store in the statedb. If we don't find the file by the name
in the database, we search for the inode number. If the inode number is found
then the file has been renamed.
Reconciliation
~~~~~~~~~~~~~~
The most important component is the update detector, because the reconciler
depends on it. The correctness of reconciler is mandatory because it can damage
a filesystem. It decides which file:
* Stays untouched
* Has a conflict
* Gets synchronized
* or is *deleted*
A wrong decision of the reconciler leads in most cases to a loss of data. So
there are several conditions which a file synchronizer has to follow.
Algorithms
^^^^^^^^^^
For conflict resolution several different algorithms could be implemented. The
most common algorithms are the merge and the conflict algorithm. The first
is a batch algorithm and the second is one which needs user interaction.
Merge algorithm
+++++++++++++++
The merge algorithm is an algorithm which doesn't need any user interaction. It
is simple and used for example by Microsoft for Roaming Profiles. If it detects
a conflict (the same file changed on both replicas) then it will use the most
recent file and overwrite the other. This means you can loose some data, but
normally you want the latest file.
Conflict algorithm
++++++++++++++++++
This is not implemented yet.
If a file has a conflict the user has to decide which file should be used.
Propagation
~~~~~~~~~~~
The next instance of the file synchronizer is the propagator. It uses the
calculated records to apply them on the current replica.
The propagator uses a two-phase-commit mechanism to simulate an atomic
filesystem operation.
In the first phase we copy the file to a temporary file on the opposite
replica. This has the advantage that we can check if the file which has been
copied to the opposite replica has been transferred successfully. If the
connection gets interrupted during the transfer we still have the original
states of the file. This means no data will be lost.
In the second phase the file on the opposite replica will be overwritten by
the temporary file.
After a successful propagation we have to merge the trees to reflect the
current state of the filesystem tree. This updated tree will be written as a
journal into the state database. It will be used during the update detection of
the next synchronization. See above for a description of the state database
during synchronization.
Robustness
~~~~~~~~~~
This is a very important topic. The file synchronizer should not crash, and if
it has crashed, there should be no loss of data. To achieve this goal there are
several mechanisms which will be discussed in the following sections.
Crash resistance
^^^^^^^^^^^^^^^^
The synchronization process can be interrupted by different events, this can
be:
* the system could be halted due to errors.
* the disk could be full or the quota exceeded.
* the network or power cable could be pulled out.
* the user could force a stop of the synchronization process.
* various communication errors could occur.
That no data will be lost due to an event we enforce the following invariant:
IMPORTANT: At every moment of the synchronization each file, has either its
original content or its correct final content.
This means that the original content can not be incorrect, no data can be lost
until we overwrite it after a successful synchronization. Therefore, each
interrupted synchronization process is a partial sync and can be continued and
completed by simply running csync again. The only problem could be an error of
the filesystem, so we reach this invariant only approximately.
Transfer errors
^^^^^^^^^^^^^^^
With the Two-Phase-Commit we check the file size after the file has transferred
and we are able to detect transfer errors. A more robust approach would be a
transfer protocol with checksums, but this is not doable at the moment. We may
add this in the future.
Future filesystems, like btrfs, will help to compare checksums instead of the
filesize. This will make the synchronization safer. This does not imply that it
is unsafe now, but checksums are safer than simple filesize checks.
Database loss
^^^^^^^^^^^^^
It is possible that the state database could get corrupted. If this happens,
all files get evaluated. In this case the file synchronizer wont delete any
file, but it could occur that deleted files will be restored from the other
replica.
To prevent a corruption or loss of the database if an error occurs or the user
forces an abort, the synchronizer is working on a copy of the database and will
use a Two-Phase-Commit to save it at the end.
Getting started
---------------
Installing csync
~~~~~~~~~~~~~~~~
See the `README` and `INSTALL` files for install prerequisites and
procedures. Packagers should take a look at <<X90, Appendix A: Packager Notes>>.
Using the commandline client
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The synopsis of the commandline client is
csync [OPTION...] SOURCE DESTINATION
It synchronizes the content of SOURCE with DESTINATION and vice versa. The
DESTINATION can be a local directory or a remote file server.
csync /home/csync scheme://user:password@server:port/full/path
Examples
^^^^^^^^
To synchronize two local directories:
csync /home/csync/replica1 /home/csync/relplica2
Two synchronizer a local directory with an smb server, use
csync /home/csync smb://rupert.galaxy.site/Users/csync
If you use kerberos, you don't have to specify a username or a password. If you
don't use kerberos, the commandline client will ask about the user and the
password. If you don't want to be prompted, you can specify it on the
commandline:
csync /home/csync smb://csync:secret@rupert.galaxy.site/Users/csync
If you use the sftp protocol and want to specify a port, you do it the
following way:
csync /home/csync sftp://csync@krikkit.galaxy.site:2222/home/csync
The remote destination is supported by plugins. By default csync ships with smb
and sftp support. For more information, see the manpage of csync(1).
Exclude lists
~~~~~~~~~~~~~
csync provides exclude lists with simple shell wildcard patterns. There is a
global exclude list, which is normally located in
'/etc/csync/csync_exclude.conf' and it has already some sane defaults. If you
run csync the first time, it will create an empty exclude list for the user.
This file will be '~/.csync/csync_exclude.conf'. csync considers both
configuration files and an additional one if you specify it.
The entries in the file are newline separated. Use
'/etc/csync/csync_exclude.conf' as an example.
Debug messages and dry run
~~~~~~~~~~~~~~~~~~~~~~~~~~
By default the csync client logs to stderr and you can increase the debug
level with a commandline options.
To simulate a run of the file synchronizer, you should set the priority to
'debug' for the categories 'csync.updater' and 'csync.reconciler' in the config
file '~/.csync/csync_log.conf'. Then run csync with the '--dry-run' option.
This will only run update detection and reconciliation.
[[X80]]
The PAM module
~~~~~~~~~~~~~~
pam_csync is a PAM module to provide roaming home directories for a user
session. This module is aimed at environments with central file servers where a
user wishes to store his home directory. The Authentication Module verifies the
identity of a user and triggers a synchronization with the server on the first
login and the last logout. More information can be found in the manpage of the
module pam_csync(8) or pam itself pam(8).
