* repo: add trace support to the launcherMike Frysinger2020-02-131-0/+24
| | | | | | | | | | Now that we have a central run_command point, we can easily add tracing support to the launcher script.

* repo: lower min version of git a bitMike Frysinger2020-02-121-1/+6
| | | | | | | | | | | | | | | | | | | | | | We were perhaps a bit too hasty to jump to git-2.10. Existing LTS releases of Ubuntu are quite old still: Trusty has 1.9 while Xenial has 2.5. While we plan on dropping support for those eventually as we migrate to Python 3.6, we don't need to be so strict just yet on the git versions. We also want to disconnect the version the repo launcher requires from the version the rest of the source tree requires. The repo launcher doesn't need as many features, and being flexible there allows us more freedom to upgrade & rollback as needed. So we'll allow git-1.7 again, but start warning on any users older than git-1.9. This aligns better with existing LTS releases, and gives users a chance to start upgrading before we cut them off.

* repo: try to reexec self with Python 3 as neededMike Frysinger2020-02-051-24/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to start warning about Python 2 usage, but we can't do it simply because the shebang is /usr/bin/python which might be an old version like python2.7. We can't change the shebang because program name usage is spotty at best: on some platforms (like macOS), it's not uncommon to not have a `python3` wrapper, only a major.minor one like `python3.6`. Using python3 wouldn't guarantee a new enough version of Python 3 anyways, and we don't want to require Python 3.6 exactly, just that minimum. So we check the current Python version. If it's older than the ver of Python 3 we want, we search for a `python3.X` version to run. If those don't work, we see if `python3` exists and is a new enough ver. If it's not, we die if the current Python 3 is too old, and we start issuing warnings if the current Python version is 2.7. This should allow the user to take a bit more action by installing Python 3 on their system without having to worry about changing /usr/bin/python. Once we require Python 3 completely, we can simplify this logic a bit by always bootstrapping up to Python 3 and failing with Python 2. We have a few KI with Windows atm though, so keep it disabled there until the fixes are merged.

* init: --dissociate option to copy objects borrowed with --referenceNikolai Merinov2018-10-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | "repo init --reference" has two purposes: to decrease bandwidth used at clone time, and to decrease disk usage afterward, by using the reference repositories as an alternate store of objects even after the clone. The downside is that it makes the borrowing repositories dependent on the reference repositories, so it is easy to end up with missing objects by mistake after a cleanup operation like "git gc". To prevent that, v2.3.0-rc0~30^2 (clone: --dissociate option to mark that reference is only temporary, 2014-10-14), "git clone" gained a --dissociate option that makes --reference reuse objects from the reference repository at clone time but copy them over instead of using the reference as an alternate. This is more straightforward to use than plain --reference, at the cost of higher disk usage. Introduce a --dissociate to "repo init" that brings the same benefits to repo. The option is simply passed on to "git clone". Change-Id: Ib50a549eb71e0a2b3e234aea57537923962a80d4

|/ | | | | | | | | | | | | | | | | | | Commit 27226e742d7e1a3d371531c19a3fdd91a4f9ab4a introduced a warning if "repo" is not part of the bootstrapped REPO_URL. However, that check was done too early, directly after the call to _Clone. As the _Clone function does not actually clone but it only initializes and fetches, the check needs to be moved to after the call to _Checkout. To reproduce, call repo init --no-clone-bundle --repo-branch=master -u https://android.googlesource.com/platform/manifest which will currently always show the (bogus) warning message. With this fix, the warning will only be shown if "repo" indeed does not exist. While at it, also slightly improve the code by using os.path.join().

| | | | | | | | | | | | | | | | repo sync can sync submodules via the --fetch-submodules option. However, if the manifest repo has submodules, those will not be synced. Having submodules in the manifest repo -- while not commonly done -- can be useful for inheriting a manifest from another project using <include> and layering changes on top of it. In this way, you can avoid having to deal with merge conflicts between your own manifests and the other project's manifests (for example, if you're managing an Android fork). Add a --submodule option to init that automatically syncs the submodules in the manifest repo whenever the manifest repo changes.
