This way we can put it in another directory than the config file

If the SSH URL doesn't contain a port number, but uses the ssh://
or git+ssh:// syntax we raised a Python runtime error due to the
'port' local variable not being assigned a value. Default it to
the IANA assigned port for SSH, 22.

Performance improvements in repo sync caused us to skip out of the
initial Sync_LocalHalf without ever running CopyFiles, so we didn't
create the top level Makefile in new clients whose manifest request
one with a <copyfile> element.
Now we run CopyFiles after the initial read-tree that populates
the project working directory.

merged into the manifest revision, but there is also at least one
unpublished commit on the current branch, we should rebase the

Mac OS X sets TMPDIR to a very long path within /var, so long
that a socket created in that location is too big for a struct
sockaddr_un on the platform, resulting in OpenSSH being unable
to create or bind to a socket in that location.
Instead we try to use the very short and very common /tmp, but
fall back to the guessed default if /tmp does not exist.

Most projects will have their branch heads matching in all branches,
so switching between them should be just a matter of updating the
work tree's HEAD symref. This can be done in pure Python, saving
quite a bit of time over forking 'git checkout'.
Signed-off-by: Shawn O. Pearce <sop@google.com>
This is mostly useful if the number of projects to switch is many
(e.g. all of Android) and a large number of them are behind the
current manifest revision. We wind up needing to run git just to
make the working tree match, and that often makes the command take
a couple of seconds longer than we'd like.

Its quite common for most projects to be matching the current
manifest revision, as most developers only modify one or two projects
at any one time. We can speed up `repo start foo` (that impacts
the entire client) by performing most of the branch creation and
switch operations in pure Python, and thus avoid 4 forks per project.

When trying to read log output from many projects at once it can
be difficult to make sense of which messages came from where.
For many professional developers it is common to want to view the
last week's worth of your work, so you can write a weekly summary
of your activity for your status report.
This is easier with the new -p option:
repo forall -pc git log --reverse --since=1.week.ago --author=sop
produces a report of all commits written by me in the last week,
formatted in a paged output display, with headers inserted in
front of each project's output.
Where this can be even more useful is with git log's pickaxe,
e.g. now we can use:
repo forall -pc git log -Sbar v1.0..v1.1
to locate all additions or removals of the symbol 'bar' since v1.0,
up to and including v1.1. Before displaying the matching commits in
a project, a project header is shown, giving the user some context
information for the matching results.

Its unlikely that a new version of repo will be delivered in any
given day, so we now check only once every 24 hours to see if repo
has been updated. This reduces the sync cost, as we no longer need
to contact the repo distribution servers every time we do a sync.
repo selfupdate can still be used to force a check.

Usually repo is upgraded only once a week, if that often. Most of
the time we invoke HasChanges on the repo project (or even on the
manifest project) the current HEAD will resolve to the same SHA-1
as the remote tracking ref, and there are therefore no changes.

The point of the progress meter is to let the user know that the
task is progressing, and give them a chance to estimate when it will
be complete. If the task completes in under 0.5 seconds then it
is sufficiently fast enough that the user doesn't need to be kept
up-to-date on its progress; in fact showing the meter may just slow
the task down waiting on the tty to redraw.
We now delay the progress meter 0.5 seconds (or 1 second if the
Python time.time() function isn't accurate enough) to avoid any
really fast tasks, like a no-op local sync.

The value of the varible TRACE was copied during the import, which

We now cache the output of `git config --list` for each of our
GitConfig instances in a Python pickle file. These can be read
back in using only the Python interpreter at a much faster rate
than we can fork+exec the git config process.
If the corresponding git config file has a newer modification
timestamp than the pickle file, we delete the pickle file and
regenerate it. This ensures that any edits made by the user
will be taken into account the next time we consult the file.

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.

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.
