To understand why this is, you need to understand a little more about how sync works in Fossil. (You can read more about the Fossil file format and the sync mechanism online - the following is a quick summary). A Fossil repository is just an unordered bag of "artifacts". Each version of each file is a separate artifact. There are also "control" artifacts that show how the various file artifacts are grouped together into versions, or that assign tags to versions, or that contain wiki or ticket edits, and so forth. The SQLite database in which the bag of artifacts is stored maintains other meta-information that helps various queries run faster. But all of that meta information can be reconstructed from the original raw artifacts. In fact, that is exactly what the "fossil rebuild" command does. A key point is that the sync mechanism does not know anything about the meta-information or the internal format of the artifacts. All sync knows is that there is some set of artifacts on one side of the connection, and another set of artifacts on the other side of the connection, and its job is to exchange differences so that both sides of the connection hold the same set of artifacts. With that in mind, you can probably see why Fossil does not do a partial sync. The sync mechanism does not know which artifacts are associated with which branches. And so it can't know which subset of artifacts to sync. -- D. Richard Hipp d...@sqlite.org
