+Sync Algorithm
+==============
+
+Overview
+--------
+
+This is a technical description of the synchronization (sync) algorithm used by the ownCloud client.
+
+The sync algorithm is the thing that looks at the local and remote file system trees and the sync journal and decides which steps need to be taken to bring the two trees into synchronization. It's different from the propagator, whose job it is to actually execute these steps.
+
+
+Definitions
+-----------
+
+  - local tree: The files and directories on the local file system that shall be kept in sync with the remote tree.
+  - remote tree: The files and directories on the ownCloud server that shall be kept in sync with the local tree.
+  - sync journal (journal): A snapshot of file and directory metadata that the sync algorithm uses as a baseline to detect local or remote changes. Typically stored in a database.
+  - file and directory metadata:
+    - mtimes
+    - sizes
+    - inodes (journal and local only): Representation of filesystem object. Useful for rename detection.
+    - etags (journal and remote only): The server assigns a new etag when a file or directory changes.
+    - checksums (journal and remote only): Checksum algorithm applied to a file's contents.
+    - permissions (journal and remote only)
+
+
+Phases
+------
+
+### Discovery (aka Update)
+
+The discovery phase collects file and directory metadata from the local and remote trees, detecting differences between each tree and the journal.
+
+Afterwards, we have two trees that tell us what happened relative to the journal. But there may still be conflicts if something happened to an entity both locally and on the remote.
+
+  - Input: file system, server data, journal
+  - Output: two c_rbtree_t*, representing the local and remote trees
+
+  - Note on remote discovery: Since a change to a file on the server causes the etags of all parent folders to change, folders with an unchanged etag can be read from the journal directly and don't need to be walked into.
+
+  - Details
+    - csync_update() uses csync_ftw() on the local and remote trees, one after the other.
+    - csync_ftw() iterates through the entities in a tree and calls csync_walker() for each.
+    - csync_walker() calls _csync_detect_update() on each.
+    - _csync_detect_update() compares the item to its journal entry (if any) to detect new, changed or renamed files. This is the main function of this pass.
+
+
+
+### Reconcile
+
+The reconcile phase compares and adjusts the local and remote trees (in both directions), detecting conflicts.
+
+Afterwards, there are still two trees, but conflicts are marked in them.
+
+  - Input: c_rbtree_t* for the local and remote trees, journal (for some rename-related queries)
+  - Output: changes c_rbtree_t* in-place
+
+  - Details
+    - csync_reconcile() runs csync_reconcile_updates() for the local and remote trees, one after the other.
+    - csync_reconcile_updates() uses c_rbtree_walk() to iterate through the entries, calling _csync_merge_algorithm_visitor() for each.
+    - _csync_merge_algorithm_visitor() checks whether the other tree also has an entry for that node and merges the actions, detecting conflicts. This is the main function of this pass.
+
+
+### Post-Reconcile
+
+The post-reconcile phase merges the two trees into one set of SyncFileItems.
+
+Afterwards, there is a list of items that can tell the propagator what needs to be done.
+
+  - Input: c_rbtree_t* for the local and remote trees
+  - Output: QMap<QString, SyncFileItemPtr>
+
+  - Note that some "propagations", specifically cheap metadata-only updates, are already done at this stage.
+
+  - Details
+    - csync_walk_local_tree() and csync_walk_remote_tree() are called.
+    - They use _csync_walk_tree() to run SyncEngine::treewalkFile() on each entry.
+    - treewalkFile() creates and fills SyncFileItems for each entry, ensuring that each file only has a single instance. This is the main function of this pass.
+
+
+See Also
+--------
+
+An overview of the propagation steps is still missing. The sync protocol is documented at https://github.com/cernbox/smashbox/blob/master/protocol/protocol.md.

-  "The Library" refers to a covered work governed by this License,
+SOFTWARE.
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  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 that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU 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 as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.
