Summary:
Fixes T3217. Ref T776. Ref T1493. Broadly, this introduces a mechanism which works like this:
- When a repository is created, we set an "importing" flag.
- After discovery completes, we check if a repository has no importing commits. Basically, this is the first time we catch up to HEAD.
- If we're caught up, clear the "importing" flag.
This flag lets us fix some issues:
- T3217. Currently, when you import a new repository and users have rules like "Email me on every commit ever" or "trigger an audit on every commit", we take a bunch of publish actions. Instead, implicitly disable publishing during import.
- An imported but un-pulled repository currently has an incomprehensible error on `/diffusion/X/`. Fix that.
- Show more cues in the UI about importing.
- Made some exceptions more specific.
Test Plan:
This is the new screen for a completely new repo, replacing a giant exception:
{F75443}
- Created a repository, saw it "importing".
- Pulled and discovered it.
- Processed its commits.
- Ran discovery again, saw import flag clear.
- Also this repository was empty, which hit some of the other code.
This is the new "parsed empty repository" UI, which isn't good, but is less broken:

Summary:
Fixes T3416. Fixes T1733.
- Adds a flag to the commit table showing whether or not we have parsed it.
- The flag is set to `0` initially when the commit is discovered.
- The flag is set to `1` when the changes are parsed.
- The UI can now use the flag to distinguish between "empty commit" and "commit which we haven't imported changes for yet".
- Simplify rendering code a little bit.
- Fix an issue with the Message parser for empty commits.
- There's a key on the flag so we can do `SELECT * FROM repository_commit WHERE repositoryID = %d AND importStatus = 0 LIMIT 1` soon, to determine if a repository is fully imported or not. This will let us improve the UI (Ref T776, Ref T3217).
Test Plan:
- Ran `bin/storage upgrade -f`.
- Created an empty commit.
- Without the daemons running, ran `bin/repository pull GTEST` and `bin/repository discover GTEST`.
- Viewed web UI to get the first screenshot ("Still Importing...").
- Ran the message and change steps with `scripts/repository/reparse.php`.
- Viewed web UI to get the second screenshot ("Empty Commit").

Differential Revision: https://secure.phabricator.com/D7421
Summary:
Fixes T2229. This sets the stage for a patch similar to D7417, but for SSH. In particular, SSH 6.2 introduced an `AuthorizedKeysCommand` directive, which lets us do this in a mostly-reasonable way without needing users to patch sshd (if they have a recent enough version, at least).
The way the `AuthorizedKeysCommand` works is that it gets run and produces an `authorized_keys`-style file fragment. This isn't ideal, because we have to dump every key into the result, but should be fine for most installs. The earlier patch against `sshd` passes the public key itself, which allows the script to just look up the key. We might use this eventually, since it can scale much better, so I haven't removed it.
Generally, auth is split into two scripts now which mostly do the same thing:
- `ssh-auth` is the AuthorizedKeysCommand auth, which takes nothing and dumps the whole keyfile.
- `ssh-auth-key` is the slightly cleaner and more scalable (but patch-dependent) version, which takes the public key and dumps only matching options.
I also reworked the argument parsing to be a bit more sane.
Test Plan:
This is somewhat-intentionally a bit obtuse since I don't really want anyone using it yet, but basically:
- Copy `phabricator-ssh-hook.sh` to somewhere like `/usr/libexec/openssh/`, chown it `root` and chmod it `500`.
- This script should probably also do a username check in the future.
- Create a copy of `sshd_config` and fix the paths/etc. Point the KeyScript at your copy of the hook.
- Start a copy of sshd (6.2 or newer) with `-f <your config file>` and maybe `-d -d -d` to foreground and debug.
- Run `ssh -p 2222 localhost` or similar.
Specifically, I did this setup and then ran a bunch of commands like:
- `ssh host` (denied, no command)
- `ssh host ls` (denied, not supported)
- `echo '{}' | ssh host conduit conduit.ping` (works)

Summary:
Mostly ripped from D7391, with some changes:
- Serve repositories at `/diffusion/X/`, with no special `/git/` or `/serve/` URI component.
- This requires a little bit of magic, but I got the magic working for Git, Mercurial and SVN, and it seems reasonable.
- I think having one URI for everything will make it easier for users to understand.
- One downside is that git will clone into `X` by default, but I think that's not a big deal, and we can work around that in the future easily enough.
- Accept HTTP requests for Git, SVN and Mercurial repositories.
- Auth logic is a little different in order to be more consistent with how other things work.
- Instead of AphrontBasicAuthResponse, added "VCSResponse". Mercurial can print strings we send it on the CLI if we're careful, so support that. I did a fair amount of digging and didn't have any luck with git or svn.
- Commands we don't know about are assumed to require "Push" capability by default.
No actual VCS data going over the wire yet.
Test Plan:

$ hg clone http://local.aphront.com:8080/diffusion/P/

Summary:
Ref T1049. I don't really want to sink too much time into this right now, but a seemingly reasonable architecture came to me in a dream. Here's a high-level overview of how things fit together:
- **"Build"**: In Harbormaster, "build" means any process we want to run against a working copy. It might actually be building an executable, but it might also be running lint, running unit tests, generating documentation, generating symbols, running a deploy, setting up a sandcastle, etc.
- `HarbormasterBuildable`: A "buildable" is some piece of code which build operations can run on. Generally, this is either a Differential diff or a Diffusion commit. The Buildable class just wraps those objects and provides a layer of abstraction. Currently, you can manually create a buildable from a commit. In the future, this will be done automatically.
- `HarbormasterBuildStep`: A "build step" is an individual build operation, like "run lint", "run unit", "build docs", etc. The step defines how to perform the operation (for example, "run unit tests by executing 'arc unit'"). In this diff, this barely exists.
- `HarbormasterBuildPlan`: This glues together build steps into groups or sequences. For example, you might want to "run unit", and then "deploy" if the tests pass. You can create a build plan which says "run step "unit tests", then run step "deploy" on success" or whatever. In the future, these will also contain triggers/conditions ("Automatically run this build plan against every commit") and probably be able to define failure actions ("If this plan fails, send someone an email"). Because build plans will run commands, only administrators can manage them.
- `HarbormasterBuild`: This is the concrete result of running a `BuildPlan` against a `Buildable`. It tracks the build status and collects results, so you can see if the build is running/successful/failed. A `Buildable` may have several `Build`s, because you can execute more than one `BuildPlan` against it. For example, you might have a "documentation" build plan which you run continuously against HEAD, but a "unit" build plan which you want to run against every commit.
- `HarbormasterBuildTarget`: This is the concrete result of running a `BuildStep` against a `Buildable`. These are children of `Build`. A step might be able to produce multiple targets, but generally this is something like "Unit Tests" or "Lint" and has an overall status, so you can see at a glance that unit tests were fine but lint had some issues.
- `HarbormasterBuildItem`: An optional subitem for a target. For lint, this might be an individual file. For unit tests, an individual test. For normal builds, an executable. For deploys, a server. For documentation generation, there might just not be subitems.
- `HarbormasterBuildLog`: Provides extra information, like command/execution transcripts. This is where stdout/stderr will get dumped, and general details and other messages.
- `HarbormasterBuildArtifact`: Stores side effects or results from build steps. For example, something which builds a binary might put the binary in "Files" and then put its PHID here. Unit tests might put coverage information here. Generally, any build step which produces some high-level output object can use this table to record its existence.
This diff implements almost nothing and does nothing useful, but puts most of these object relationships in place. The two major things you can't easily do with these objects are:
1) Run arbitrary cron jobs. Jenkins does this, but it feels tacked on and I don't know of anyone using it for that. We could create fake Buildables to get a similar effect, but if we need to do this I'd rather do it elsewhere in general. Build and cron/service/monitoring feel like pretty different problems to me.
2) Run parameterized/matrix steps (maybe?). Bamboo has this plan/stage/task/job breakdown where a build step can generate a zillion actual jobs, like "build client on x86", "build server on x86", "build client on ARM", "build server on ARM", etc. We can sort of do this by having a Step map to multiple Targets, but I haven't really thought about it too much and it may end up being not-great. I'd guess we have like an 80% chance of getting a clean implementation if/when we get there. I suspect no one actually needs this, or when they do they'll just implement a custom Step and it can be parameterized at that level. I'm not too worried about this overall.
The major difference between this and Jenkins/Bamboo/TravisCI is that all three of those are **plan-centric**: the primary object in the system is a build plan, and the dashboard shows you all your build plans and the current status. I don't think this is the right model. One disadvantage is that you basically end up with top-level messaging that says "Trunk is broken", not "Trunk was broken by commit af32f392f". Harbormaster is **buildable-centric**: the primary object in the system is stuff you can run build operations against (commits/branches/revisions), and actual build plans are secondary. The main view will be "recent commits on this branch, and whether they're good or not" -- which I think is what's most important in a larger/more complex product -- not the pass/fail status of all jobs. This also makes it easier and more natural to integrate with Differential and Diffusion, which both care about the overall status of the commit/revision, not the current status of jobs.
Test Plan: Poked around, but this doesn't really do anything yet.
