Summary:
- Add flags to exit after an idle time or client count.
- Add flags to control daemonization.
- Add flags to control output.
- Add flags to skip the "hello" frame of the protocol.
- Make the client launch a server if one does not exist.
The one-time overhead to launch a server and run a command through it looks to be ~130% of the overhead to run the command directly with "hg", so even if we never run a second command we're not paying too much.
The incremental overhead to run subsequent command appears to be less than 3% of the overhead to run the command directly with "hg" (and maybe less than 1%, I'm not sure how long the computation part of a command like 'hg log' "actually" takes).
The overhead to launch a PHP client, connect to an existing server, run a command, and then print it and exit is roughly 50% of the overhead to run the command directly with "hg". So theoretically a user can achieve an amortized 2x performance increase for all 'hg' commands by aliasing 'hg' to the PHP client in their shell.
Test Plan:
- Ran servers with idle and client count limits, let them idle and/or hit their connection limits, saw them exit.
- Ran foreground and background servers.
- Ran a daemon server with redirected stdout/stderr. Verified logs appeared.
- Ran with --quiet.
- Ran clients and servers with and without --skip-hello, things work if they agree and break if they disagree. The throughput gain on this is fairly small (maybe 5%?) but it seems simple enough to keep for the moment.
- Ran serverless clients and verified that servers launched the first time, were available subsequently, and relaunched after 15 seconds idle.

Summary:
- Move "arc branch"-specific code to the branch workflow.
- Instead of doing "git rev-parse", just do "git branch --verbose --abbrev=40".
- Use revision owners to identify ownership, not working copy identity. Particularly with the advent of "Commandeer", you might not own commits you made.
- Do a batch lookup for commits by hash (depends on D2859, but doesn't break without it).
- Use PhutilConsole for console stuff.
- Removed color from "arc list" for the moment.
- The "--by-status" flag has a slightly different output format now.
Test Plan: Ran "arc branch" in various circumstances, verified it identifies branches in immutable history repositories.

svn 1.7 got rid of the per-direcotry .svn dirs in favor of a single
.svn directory under the root of the working copy. Unfortunately, we
relied on ther being a .svn directory at the same level as .arcconfig,
which may or may not be at the root of the working copy. We now walk
up the directory tree until we find a .svn directory that we can use
for scratch files.

Summary:
New optional mode. If you set 'base' in local, project or global config or pass '--base' to 'arc diff' or 'arc which', it switches to DSL mode.
In DSL mode, lists of rules from args, local, project and global config are resolved, in that order. Rules can manipulate the rule machine or resolve into actual commits. Provides support for some 'arc' rules (mostly machine manipulation) and 'git' rules (symbolic ref and merge-base).
Test Plan:
Ran unit tests. Also:
```$ arc which --show-base --base 'arc:prompt'
Against which commit? HEAD

$ arc which --show-base --base 'git:HEAD'

$ arc which --show-base --base 'git:fake'

Summary:
Spamming everyone who got bitten by this. We upgraded the libphutil library system recently, but the "use of undeclared function" lint check used to run only on files you touched and now runs on every file in every library you use. This means that if you don't have pcntl or ldap installed, you'll get errors about use of functions from them on every change.
Instead, ship with a list of functions which are provided by extensions that we'll ignore when calculating dependencies, so not having pcntl doesn't mean you have to excuse through irrelevant errrors every time.
Test Plan: Ran script with an unknown function, got it in the map; added it to the extension list, it vanished from the map.

for git. This diff consists of 2 commits, one for the .gitignore and
one for everything else.
Comment out the portion of my .git/config that defines the upstream

.arc/default-relative-commit. See that .gitignore is not included in
the resultant diff, that .arc no longer exists, and that .git/arc
