These tags can be applied recursively (`TOPIC-SUBTOPIC-SUBSUBTOPIC`). *private* vs. *public* does, of course, in this scenario not mean visibility, but instead authority: *private* branches are those that the user `SAVANNAH_LOGIN` has authority over, whereas public branches are open for every committer to install changes on. The private branches are those that you would typically host on your own machine and publish through your own web server, but we offer that you can instead do this from the centralized Savannah repository, as a number of people don't have an always-accessible web server running on their own machines. Examples: * GNU Mach * `master` -- the mainline branch * `master-oskit` -- port to OSKit; branched off of `master` at some point * `master-gdb_stubs` -- add support for GDB stubs; branched off of `master` at some point * libpthread * `master` -- the mainline branch * `master-viengoos` -- port to Viengoos; branched off of `master` at some point * `master-viengoos-on-bare-metal` -- port to Viengoos running on bare metal; branched off of `master-viengoos` at some point ## Merging Merging between Git branches is trivial, at least as long as no conflicts arise. Due to this, you are encouraged to freely make use of separate branches for different working topics, as this really faciliates concentrating on one specific working topic. You are encouraged to regularely merge from the respective mainline branches (`BASE_BRANCH`; should be `master` in most cases) into your working branches, and ensure that your modifications are still fine in the context of new mainline changes. Merging from working branches into the mainline branches will usually be done by one of the project administrators, unless negotiated otherwise. For this to happen, the copyright of your changes has to be assigned to the Free Software Foundation; read about the [[copyright_assignment_process|savannah_group#copyright_assignment]]. # Tags Equivalent rules apply. # Behavior Try to not introduce spurious, unneeded changes, e.g., whitespace changes. Adhere to the coding conventions that are already used. These are usually the [GNU Coding Standards](http://www.gnu.org/prep/standards/html_node/) for stuff written by ourselves, including new files, of course. GNU Mach code is largely based on external code. Don't GNU-ify it, as this would make merging external patches unnecessarily difficult. ## Behavior on branches Usually, branches are to be eventually merged back into their respective mainline branches. To faciliate (and also to help other contributors) we'd like you to write a short summary log in a top-level (or wherever else appropriate) `ChangeLog.TOPIC` file. Examples: * GNU Mach * `master-gdb_stubs`: `ChangeLog.gdb` This need not be a full-fledged [GNU-style `ChangeLog` file](http://www.gnu.org/prep/standards/html_node/Change-Logs.html). E.g., don't waste time writing `ChangeLog` entries for debugging stuff that will be removed again before merging back into mainline. But please do write something. Short notes. ### Behavior on *private* branches Even though you are said to be the owner of branches tagged with your `SAVANNAH_LOGIN`, it is generally nevertheless good to not do history-rewriting stuff and the like (`git rebase` and friends), as others may in turn be basing their work on your private branches. We could establish a branch-tagging policy for branches that others should expect their history possibly to be rewritten. This may be useful for branches that are only meant for aggregating the changes of (several) development branches, like `master-proposed_for_general_testing`.
