Summary:
Depends on D7498.
This implements support for a "build step implementation". Build steps have an associated class name (which makes the class in PHP) and a details field, which is serialized JSON (same as PhabricatorRepository).
This also implements a SleepBuildStepImplementation which just pauses the build for a specified period of seconds.
Test Plan:
Inserted a build step with `insert into harbormaster_buildstep (phid, buildPlanPHID, className, details, dateCreated, dateModified) values ('', 'PHID-HMCP-zkh5w6czfbfpk2gxwdeo', 'SleepBuildStepImplementation', '{"seconds":5}', NOW(), NOW());` (adjusting the build plan PHID as appropriate).
Started the daemon and applied the build plan to a buildable, and saw the daemon take a 5 second delay after creating `SleepBuildStepImplementation`.

Summary:
`RepositoryStatusMessage` is basically a key/value table associated with a repository that I'm using to let the daemons store the most recent event of a given type, so we can easily show it on the status dashboard. I think this will be a lot easier for users to figure out than digging through logfiles.
I'm also going to write the "this needs a pull" status here eventually, for reducing the time lapse between pushes and discovery.
- Add storage for these messages.
- Have the pull engine populate the INIT phase. I'll do the FETCH phase next.
- Update the status readout to show all the various states.

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").

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:
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.

Summary:
Ref T1344. This is //very// rough. Some UI issues:
- Empty states for the board and columns are junky.
- Column widths are crazy. I think we need to set them to fixed-width, since we may have an arbitrarily large number of columns?
- I don't think we have the header UI elements in M10 yet and that mock is pretty old, so I sort of very roughly approximated it.
- What should we do when you click a task title? Popping the whole task in a dialog is possible but needs a bunch of work to actually work. Might need to build "sheets" or something.
- Icons are slightly clipped for some reason.
- All the backend stuff is totally faked.
Generally, my plan is just to use these to implement all of T390. Specifically:
- "Kanban" projects will have "Backlog" on the left. You'll drag them toward the right as you make progress.
- "Milestone" projects will have "No Milestone" on the left, then "Milestone 9", "Milestone 8", etc.
- "Sprint" projects will have "Backlog" on the left, then "Sprint 31", "Sprint 30", etc.
So all of these things end up being pretty much exactly the same, with some minor text changes and new columns showing up on the left vs the right or whatever.

Summary:
Ref T2222. This implements step (1) described there, which is moving over all the inline comments.
The old and new tables are simliar. The only real trick here is that `transactionPHID` and `legacyCommentID` mean roughly the same thing (`null` if the inline is a draft, non-null if it has been submitted) but we don't have real `transactionPHID`s yet. We just make some up -- we'll backfill them later.
Two risks here:
- I need to take a second look at the keys on this table. I think we need to tweak them a bit, and it will be less disruptive to do that before this migration than after.
- This will take a while for Facebook, and other large installs with tens of thousands of revisions. I'll communicate this.
I'm otherwise pretty satisfied with this, seems to work well and is pretty low risk / non-disruptive.
Test Plan:
- Before migrating, then after migrating:
- Made a bunch of inlines (drafts, submitted).
- Edited and deleted inlines.
- Verified inlines showed up in preview.
- Verified that inlines aren't indexed when they're drafts (`bin/search index D935`).
- Verified that inlines ARE indexed when they're not drafts.
- Verified that drafts inlines make revisions appear as "with draft" in the revision list.
- Made left, right, and draft inlines.
- Migrated (`bin/storage upgrade`).

Summary:
Ref T2217. This is the risky, hard part; everything after this should be smooth sailing. This is //mostly// clean, except:
- The old format would opportunistically combine a comment with some other transaction type if it could. We no longer do that, so:
- When migrating, "edit" + "comment" transactions need to be split in two.
- When editing now, we should no longer combine these transaction types.
- These changes are pretty straightforward and low-impact.
- This migration promotes "auxiliary field" data to the new CustomField/StandardField format, so that's not a straight migration either. The formats are very similar, though.
Broadly, this takes the same attack that the auth migration did: proxy all the code through to the new storage. `ManiphestTransaction` is now just an API on top of `ManiphestTransactionPro`, which is the new storage format. The two formats are very similar, so this was mostly a straight copy from one table to the other.
Test Plan:
- Without performing the migration, made a bunch of edits and comments on tasks and verified the new code works correctly.
- Droped the test data and performed the migration.
- Looked at the resulting data for obvious discrepancies.
