sync: respect `sync-c` manifest option The documentation states that a `sync-c` attribute in the manifest file can set a default for whether only the current branch should be fetched or all branches. This seems to have been broken for some time. Commit 7356114 introduced the `--no-current-branch` CLI option and relied on getting `None` via `optparse` if neither `--current-branch` nor `--no-current-branch` was set to distinguish it from a boolean value. If `None` was received, it would read the value from the manifest option `sync-c`. The parsing went through the utility function `_GetCurrentBranchOnly` which returned `True` if `--current-branch` had been given on the command-line, or fell back on the "superproject" setting, which would either return `True` or `None`. This would incorrectly make `repo` fall back to the manifest setting even if the user had given `--no-current-branch` if no superproject was requested -- the manifest became "too powerful": Command-line Using superproject → `current_branch_only` ------------ ------------------ ----------------------- No From manifest Yes True --current-branch No True --current-branch Yes True --no-current-branch No From manifest ← wrong --no-current-branch Yes True In commit 0cb6e92 the superproject configuration value reading changed from something that could return `None` to something that always returned a boolean. If it returned `False`, this would then incorrectly make `repo` ignore the manifest option even if neither `--current-branch` nor `--no-current-branch` had been given. The manifest default became useless: Command-line Using superproject → `current_branch_only` ------------ ------------------ ----------------------- No False ← wrong Yes True --current-branch No True --current-branch Yes True --no-current-branch No False --no-current-branch Yes True By swapping the order in which the command-line option target and the superproject setting is evaluated, things should work as documented: Command-line Using superproject → `current_branch_only` ------------ ------------------ ----------------------- No From manifest Yes True --current-branch No True --current-branch Yes True --no-current-branch No False --no-current-branch Yes True Change-Id: I933c232d2fbecc6b9bdc364ebac181798bce9175 Tested-by: Daniel Andersson <daniel.r.andersson@volvocars.com> Reviewed-on: https://gerrit-review.googlesource.com/c/git-repo/+/334270 Reviewed-by: Mike Frysinger <vapier@google.com>
