project: detach HEAD in internal worktree checkout.

2020-12-26T07:30:40+00:00

When checkout is done with Git worktrees then the HEAD in the bare-git repositories point to the initialized default (e.g. 'refs/heads/master'). This default branch does not exist locally and is not automatically created. When a user now creates a branch in any git repository named 'master' then it is no longer possible to get rid of this branch, neither is it possible to switch to another branch and switch back to this master branch. Git concludes the 'master' branch is already checked out (in the bare Git) and that results in a lockdown of this master branch. To repoduce this issue, run these commands in a repo tree checked out with --worktree: - git checkout master # assuming the remote repo has a master branch, # a local tracking branch master is created here - git checkout -b temp - git checkout master # This one now fails - git branch -d master # fails too The failure is caused by Git assuming the master branch is checked out by the bare git repository since HEAD is pointing towards it. To workaround this, we always detach HEAD in the bare-git when syncing. We don't need it to point to a ref in general, but we would like it to be valid so git tools "just work" if they're run in here.

Fix --reference option under Windows

2020-11-23T09:17:32+00:00

When intializing a new repo with the --reference option on Windows 10 the objects/info/alternates in each git repository is created with Windows line endings (\r\n), leading to the following error: error: object directory C://.git/objects? does not exist; check .git/objects/info/alternates This can be fixed by simply using unix line endings on both Windows and unix platforms.

Always use Unix EOL for worktree .git and gitdir files

2020-11-20T20:53:43+00:00

Worktree .git and gitdir reference files are written by Git with Unix line ending, even on Windows & macOS. The conversion to relative paths makes these files end with DOS line endings in Windows. The Git integration in Visual Studio 2019 cannot deal with these DOS line endings and considers these worktrees invalid.

manifest_xml: refactor manifest parsing from client management

2020-11-18T19:10:57+00:00

We conflate the manifest & parsing logic with the management of the repo client checkout in a single class. This makes testing just one part (the manifest parsing) hard as it requires a full checkout too. Start splitting the two apart into separate classes to make it easy to reason about & test.

The project.py file is huge and contains multiple classes. By moving it to seperate class files the code becomes more readable and maintainable.

init: use the remote default manifest branch

2020-09-09T05:46:07+00:00

Instead of hardcoding "master" as our default, use the remote server's default branch instead. For most people, this should be the same as "master" already. For projects moving to "main", it means we'll use the new name automatically rather than forcing people to use -b main. For repositories that never set up a default HEAD, we should still use the historical "master" default.

status: Use multiprocessing for `repo status -j` instead of threading

2020-09-09T03:52:24+00:00

This change increases the speed of the command with parallelization with processes. The parallelization with threads doesn't work well, and increasing the number of jobs to many (8 threads ~) didn't increase the speed. Possibly, the global interpreter lock of Python affects.

project.py: Fix check for wild cards

2020-05-05T17:53:11+00:00

The intention of the check is to verify whether the target file name contains a wild card. The code, however, assumes that if the file is non-existent - it contains a wild card. This has the side effect that a target file that does not exist at the moment of the check is considered to contain a wild card, this leads itself to softlink not being created.
