Generally we only show the project path, relative from the top of the

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
happens before the --trace option can be processed. So instead we

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.
This reduces the time for a no-op repo sync from 0.847s to 0.269s.

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.
Signed-off-by: Shawn O. Pearce <sop@google.com>
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.

We now try to sync all projects that can be done safely first, before
we start rebasing user commits over the upstream. This has the nice
effect of making the local tree as close to the upstream as possible
before the user has to start resolving merge conflicts, as that extra
information in other projects may aid in the conflict resolution.
Informational output is buffered and delayed until calculation for
all projects has been done, so that the user gets one concise list
of notice messages, rather than it interrupting the progress meter.
Fast-forward output is now prefixed with the project header, so the
user can see which project that update is taking place in, and make
some relation of the diffstat back to the project name.
Rebase output is now prefixed with the project header, so that if
the rebase fails, the user can see which project we were operating
on and can try to address the failure themselves.
Since rebase sits on a detached HEAD, we now look for an in-progress
rebase during sync, so we can alert the user that the given project
is in a state we cannot handle.

rebase interactive (aka rebase -i) has changed in newer versions
of git, and doesn't always generate the sequence of commits the
same way it used to. It also doesn't handle having a previously
applied commit try to be applied again.
The default rebase algorithm is better suited to our needs.
It uses --ignore-if-in-upstream when generating the patch series
for git-am, and git-am with its 3-way fallback is able to handle
a rename case just as well as the cherry-pick variant used by -m.
Its also a generally faster implementation.

If `repo start foo` fails due to uncommitted and unmergeable changes
in a single project, we have switched half of the projects over to
the new target branches, but didn't on the one that failed to move.
This change improves the situation by doing three things differently:
- We keep going when we encounter an error, so other projects
that can successfully switch still switch.
- We ignore projects whose current branch is already on the
requested name; they are logically already setup.
- We checkout the branch if it already exists, rather than
trying to recreate the branch.

The repo script often uses a pager by default and will produce
control characters (coloring) to standard output when using the
pager, even if the output is redirected to another pipe or script.
This is because the pager setup checked for the terminal presence

the terminal.
Instead require that both FD 0 and FD 1 are connected to the terminal
in order to start the pager.

If the user has multiple projects to upload changes to, and they

If /ssh_info is protected by an HTML based login page, we may get
back a "200 OK" response from the server with some HTML document
asking us to authenticate. This can't be parsed into a host name
and port number, so we shouldn't even try.
Valid host names and decimal port numbers cannot contain '<', but
an unexpected HTML login page would. So we test for '<' to give
us a fair indicator that the content isn't what we think it is,
and bail out.

Modern Gerrit2 automatically outputs the URL for each commit to
