a6c52f566a Set tracing to always on and save to .repo/TRACE_FILE.
- add `--trace_to_stderr` option so stderr will include trace outputs and any other errors that get sent to stderr
- while TRACE_FILE will only include trace outputs

6d1faa1db3 git_refs: fix crash with binary . files in .git/refs/
On macOS, the Finder app likes to poop .DS_Store files in every path
that the user browses.  If the user pokes around the .git/ tree, it
could generate a .DS_Store file in there too.  When repo goes to read
all the local refs, it tries to decode this binary file as UTF-8 and
subsequently crashes.

Since paths that begin with . are not valid refs, ignore them like we
already do with paths that end in .lock.  Also bump the check up to
ignore dirs that match since that follows the git rules: they apply
to any component in its path, not just the final path (name).

We don't implement the full valid ref algorithm that git employs as
it's a bit complicated, and we only really need to focus on what will
practically show up locally.

21b7fbe14d project: fix m/ pseudo ref handling with git worktrees
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.

bed8b62345 Add support for long paths
* 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

9ead97bb51 When starting a branch, do not use a tag or change value for branch.merge
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.

* Fix imports.
* Use python3 syntax.
* Wrap map() calls with list().
* Use list() only wherever needed.
  (Thanks Conley!)
* Fix dictionary iteration methods
  (s/iteritems/items/).
* Make use of sorted() in appropriate places
* Use iterators directly in the loop.
* Don't use .keys() wherever it isn't needed.
* Use sys.maxsize instead of sys.maxint

TODO:
* Make repo work fully with python3. :)

Some of this was done by the '2to3' tool [1], by
applying the needed fixes in a way that doesn't
break compatibility with python2.

fbcde472ca Improve repo sync performance by avoid git forks
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.

d237b69865 Implement git ref reading purely in Python
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.
