* project: fix m/ pseudo ref handling with git worktreesMike Frysinger2020-02-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since most ref namespaces are shared among all worktrees, trying to set the pseudo m/<branch> in the common git repo ends up clobbering each other when using shared checkouts. For example, in CrOS: <project path="src/third_party/kernel/v3.8" name="chromiumos/third_party/kernel" revision="refs/heads/chromeos-3.8" /> <project path="src/third_party/kernel/v3.10" name="chromiumos/third_party/kernel" revision="refs/heads/chromeos-3.10" /> Trying to set m/master in chromiumos/third_party/kernel.git/ will keep clobbering the other. Instead, when using git worktrees, lets set the m/ pseudo ref to point into the refs/worktree/ namespace which is unique to each git worktree. So we have in the common dir: chromiumos/third_party/kernel.git/: refs/remotes/m/master: ref: refs/worktree/m/master And then in each worktree we point refs/worktree/m/master to the respective manifest revision expression. Now people can use the m/master in each git worktree and have it resolve to the right commit for that worktree.

* use open context managers in more placesMike Frysinger2019-11-121-10/+3
| | | | | | | | | | Use open() as a context manager to simplify the close logic and make the code easier to read & understand. This is also more Pythonic.

* Add support for long pathsRenaud Paquay2018-10-221-2/+3
| | | | | | | | | | | | | | | | | | | | * Add more file i/o wrappers in platform_utils to allow using long paths (length > MAX_PATH) on Windows. * Paths using the long path syntax ("\\?\" prefix) should never escape the platform_utils API surface area, so that this specific syntax is not visible to the rest of the repo code base. * Forward many calls from os.xxx to platform_utils.xxx in various place to ensure long paths support, specifically when repo decides to delete obsolete directories. * There are more places that need to be converted to support long paths, this commit is an initial effort to unblock a few common use cases. * Also, fix remove function to handle directory symlinks Change-Id: If82ccc408e516e96ff7260be25f8fd2fe3f9571a

* When starting a branch, do not use a tag or change value for branch.mergeZac Livingston2017-08-251-5/+6
| | | | | | | | | | | | | When starting a branch, branch.merge is set to project revision unless the revision is a SHA1. In that case, branch.merge is set to dest_branch if defined or manifest default revision otherwise. This special handling allows repo upload to work when the project revision is a SHA1. Extend the special handling to also happen when the project revision is a tag value or a change value so that repo upload will work in those case as well.

* Improve repo sync performance by avoid git forksShawn O. Pearce2009-04-171-0/+11
| | | | | | | | | | | By resolving the current HEAD and the manifest revision using pure Python, we can in the common case of "no changes" avoid a lot of git operations and directly jump out of the local sync method. This reduces the no-op `repo sync -l` time for Android's 114 projects from more than 6s to under 0.8s. Signed-off-by: Shawn O. Pearce <sop@google.com>
* Implement git ref reading purely in PythonShawn O. Pearce2009-04-171-0/+133
Its much faster to read the refs from 114 projects when the reader is pure Python and just doing file IO than forking 114 git commands and parsing their output. The reader caches refs based upon file mtimes. If any single ref file has been modified since the last read, we re-read the entire repository's ref namespace. This simplifies the code as we don't need to worry about shooting down symbolic-refs, but it may cause more IO than is necessary if only one ref gets updated. This change drops `repo branches` in Android from 1.658s to 0.206s. Likewise, `repo sync` improves dramatically as well. Signed-off-by: Shawn O. Pearce <sop@google.com>
