845a7d8716 Allow the PullLocal daemon to actually hibernate
Summary:
Ref T12298. The PullLocal daemon has had hibernation code for a little while, but it never actually activated because we don't sleep for more than 15 seconds in any case.

Add a maximum sleep instead and use that to control the longest sleep we'll do for hibernation purposes.

Also, when a repository or repository URI is edited, write a NEEDS_UPDATE event into the message table to make sure the daemons de-hibernate.

Test Plan: Used `bin/phd debug pull`, saw the daemon actually hibernate instead of just sleeping for 15 seconds.

Summary: Ref T12298. This allows the PullLocal daemon to hibernate like the Trigger daemon, but automatically wakes it back up when it needs to do something.

Test Plan:
  - Ran `bin/phd debug pulllocal --trace`.
  - Saw the daemon hibernate after doing a checkup on repositories.
  - Saw periodic queries to look for new update messages.
  - After clicking "Update Now" in the web UI to schedule an update, saw the daemon wake up immediately.

972604e0e5 Set TERM to prevent No entry for terminal type "unknown" messages during fetch
Summary:
Fetches cause output in `/var/tmp/phd/log/daemons.log` as

```
PHLOG: 'Unexpected output while updating repository "rREPONAME": No entry for terminal type "unknown";

```

These warnings come from PHP itself.  Silence these warnings by providing a
known value for `TERM` before shelling out to the PHP script.

See also D9744 (reverted in D11644) and T4990/T7119, which are a similar issue,
but in the pre-receive hooks, not the pull daemons.

e41a64607e Retain repository update cooldowns across daemon restarts
Summary:
Ref T11665. Fixes T7865. When we restart the daemons, the repository pull daemon currently resets the cooldowns on all of its pulls. This can generate a burst of initial load when restarting a lot of instance daemons (as in the Phacility cluster), described in T7865. This smooths things out so that recent pulls are considered, and any repositories which were waiting keep waiting.

Somewhat counterintuitively, hosted repositories write `TYPE_FETCH` status messages, so this should work equally well for hosted and observed repositories.

This also paves the way for better backoff behavior on repository errors, described in T11665. The error backoff now uses the same logic that the standard backoff does. The next change will make backoff computation consider recent errors.

(This is technically too large for repositories which have encountered one error and have a low commit rate, but I'll fix that in the following change; this is just a checkpoint on the way there.)

Test Plan: Ran `bin/phd debug pull`, saw the daemon compute reasonable windows based on previous pull activity.

9a2c2505a0 Handle tag tags properly in discovery
Summary:
Fixes T11180. In Git, it's possible to tag a tag (????). When you do, we try to log the tag-object, which automatically resolves to the commit and fails.

Just skip these. If "A" points at "B" which points at "C", it's fine to ignore "A" and "B" since we'll get the same stuff when we process "C".

Test Plan:
  - Tagged a tag.
  - Pushed it.
  - Discovered it.
  - Before patch: got exception similar to the one in T11180.
  - After patch: got tag-tag skipped. Also got slightly better error messages.

984dff0ae3 Provide a more consistent, mostly relaxed severity for updating non-cluster repositories on cluster devices
Summary:
Fixes T10940. Two issues currently:

First, `PullLocal` deamon refuses to update non-cluster repositories on cluster devices. However, this is surprising/confusing/bad because as soon as you enroll a repository host in the cluster, most of the repositories on it stop working until you `clusterize` them. This is especially confusing because the documentation gives you a very nice, gradual walkthrough about going through things slowly and being able to check your work at every step, but we really drop you off a bit of a cliff here. The workflow implied by the documentation is a desirable one.

This operation is generally only unsafe/problematic if the daemon would be creating a //new// working copy. If a working copy already exists, we can reasonably guess that it's almost certainly because you've enrolled a previously un-clustered host into a new cluster. This allows the nice, gradual workflow the documentation describes to proceed as expected, without any weird surprises.

Instead of refusing to update these repositories, only refuse to update them if updating would create a new working copy. This should make transitioning much smoother without any meaningful reduction in safety.

Second, the lower-level `bin/repository update`, `refs`, `mirror`, etc., commands don't apply this same check. However, these commands are potentially just as dangerous. Use the same code to do a similar check there, making sure we only operate on repositories that are either expected to be on the current device, or which already exist here.

Test Plan:
  - Ran `bin/phd debug pull`, saw diagnostic information choose to update most repositories (including some non-cluster repositories) but properly skip non-cluster repositories that do not exist locally.
  - Ran `bin/repository update`, etc., saw the command apply consistent rules to the rules applied by `PullLocal` and refuse to update non-local repositories it would need to create.

In particular, I need to cache Spaces (they are frequently accessed, sometimes by multiple viewers) but not have them survive longer than the scope of one request.

This request cache is explicitly destroyed by each web request and each daemon request.

fca8b5ab1b Improve UX for repository updates
Summary:
Fixes T5926. Fixes T5830. Ref T4767. Users currently sometimes have a hard time understanding repository update frequencies. This is compounded by aggressive backoff and incorrect backoff while importing repositories.

  - Don't back off while importing repositories. This prevents us from hanging at 99.99% for inactive repositories while waiting for the next update.
  - Back off less aggressively in general, and even more gradually during the first 3 days. This should make behavior around weekends better.

5671c4b276 Make PullLocal daemon more flexible and transparent about scheduling
Summary:
Ref T4605. Fixes T3466. The major change here is that we now run up to four simultaneous updates. This should ease cases where, e.g., one very slow repository was blocking other repositories. It also tends to increase load; the next diff will introduce smart backoff for cold repositories to ease this.

The rest of this is just a ton of logging so I can IRC debug these things by having users run them in `phd debug pulllocal` mode.

For T3466:

  - You now have to hit four simultaneous hangs to completely block the update process.
  - Importing repository updates are killed after 4 hours.
  - Imported repository updates are killed after 15 minutes.

Test Plan:
  - Ran `phd debug pulllocal` and observed sensible logs and behavior.
  - Interrupted daemon from sleeps and processing with `diffusion.looksoon`.
  - Ran with various `--not`, `--no-discovery` flags.

118c696f72 Separate repository updates from the pull daemon
Summary:
Ref T4605. Currently, the PullLocal daemon is responsible for two relatively distinct things:

  - scheduling repository updates; and
  - actually updating repositories.

Move the "actually updating" part into a new `bin/repository update` command, which basically runs the pull, discover, refs and mirror commands. This will let the parent process focus on scheduling in a more understandable way and update multiple repositories at once. It also makes it easier to debug and understand update behavior since the non-scheduling pipeline can be run separately.

Test Plan:
  - Ran `update --trace` on SVN, Mercurial and Git repos.
  - Ran PullLocal daemon for a while without issues.

220addb249 Move Git discovery into DiscoveryEngine
Summary:
Ref T4327. Consolidates and simplifies infrastructure:

  - Moves Git discovery into DiscoveryEngine.
  - Collapses a bunch of the Git and Mercurial code related to stream discovery.
  - Removes all cach code from PullLocal daemon (it's no longer called).
  - Adds basic unit tests for Git and Mercurial discovery.

Various cleanup:

  - Makes GitStream and MercurialStream extend a common base.
  - Improves performance of MercurialStream in some cases, by requiring fewer commits be output and parsed.
  - Makes mirroring exceptions easier to debug.
  - Fixes discovery of Mercurial repositories with multiple branch heads.
  - Adds some missing `pht()`.

Test Plan:
I tested this fairly throughly because I think this phase is complete:

  - Made new repositories in multiple VCSes and did full imports.
    - Particularly, I reimported Arcanist to make sure that TODO was resolved. I think it was related to the toposort stuff.
  - Pushed commits to multiple VCSes.
  - Pushed commits to a non-close branch, then pushed a merge commit. Observed commits import initially as non-close, then get flagged for close.
  - Started full daemons and resolved various minor issues that showed up in the daemon log until everything ran cleanly.
  - Basically spent about 30 minutes banging on this in every way I could think of to try to break it. I found and fixed some minor stuff, but it seems solid.

618da2265d Remove all the multi-pass autoclose-branch separate-cache / seenOnBranches junk
Summary:
Ref T4327. Simplify the git discovery process so I can move it to the DiscoveryEngine, so I can make change parsing testable.

In particular:

  - As an optimization, we process closeable branches ("master") first, then process uncloseable branches ("epriestley-devel"). This means that in the common case we can insert a commit as closeable immediately when it is discovered, the first pass through the pipeline will get it right, and the "ref update" step will never need to do any meaningful work.
  - Commits which do not initially appear on a closeable branch, but later move to one (via merges or ref moves) will now be caught in the ref update step, have the closeable flag set, and have a message step re-queued.
  - We no longer need to do a separate discovery step on closable branches.
  - We no longer need to keep track of `seenOnBranches`.

Test Plan: Ran discovery on repositories after pushing commits, got reasonable results.

f4b9efe256 Introduce ref cursors for repository parsing
Summary:
Ref T4327. I want to make change parsing testable; one thing which is blocking this is that the Git discovery process is still part of `PullLocal` daemon instead of being part of `DiscoveryEngine`. The unit test stuff which I want to use for change parsing relies on `DiscoveryEngine` to discover repositories during unit tests.

The major reason git discovery isn't part of `DiscoveryEngine` is that it relies on the messy "autoclose" logic, which we never implemented for Mercurial. Generally, I don't like how autoclose was implemented: it's complicated and gross and too hard to figure out and extend.

Instead, I want to do something more similar to what we do for pushes, which is cleaner overall. Basically this means remembering the old branch heads from the last time we parsed a repository, and figuring out what's new by comparing the old and new branch heads. This should give us several advantages:

  - It should be simpler to understand than the autoclose stuff, which is pretty mind-numbing, at least for me.
  - It will let us satisfy branch and tag queries cheaply (from the database) instead of having to go to the repository. We could also satisfy some ref-resolve queries from the database.
  - It should be easier to extend to Mercurial.

This implements the basics -- pretty much a table to store the cursors, which we update only for Git for now.

Test Plan:
  - Ran migration.
  - Ran `bin/repository discover X --trace --verbose` on various repositories with branches and tags, before and after modifying pushes.
  - Pushed commits to a git repo.
  - Looked at database tables.

0ac58d7db6 Move repository URI normalization out of PullLocalDaemon
Summary: Ref T4327. Moves us one small step forward toward testable change parsers by separating out this unrelated logic from the PullLocal daemon. We will also probably want to run this logic so we can do remote path lookups to limit the role of Arcanist Projects in the future, which is why I made the URI type (here, only "git") a parameter rather than calling this a `GitURINormalizer` or something.

Test Plan:
  - Ran unit tests.
  - Ran `repository discover` on a correctly-configured remote repository.
  - Ran `repository discover` on an incorrectly-configured remote, got an error message.

a07f444f2a Fix git "origin" remote in more circumstances
Summary:
Fixes T4041. We currently detect when "origin" is incorrect, but can do better:

  - When "origin" is missing, we can add it. This happens for Git 1.7.1 -- see T4041.
  - When "origin" is wrong, we can fix it automatically if we control the repository.

We only need to fail when origin exists, is wrong, and we aren't in charge of the repository.

Test Plan: Ran `bin/repository discover X` on a repository with a good origin, no origin, a bad-but-under-control origin, and a bad-out-of-control origin. Got the right behavior in all cases.

3607bd487c Survive pull/discover for hosted repositories in all VCSes
Summary:
Hosted repositories only sometimes survive the pull/discover phases right now, due to issues like:

  - Pull tries to `git clone`, but should `git init`.
  - Mercurial doesn't handle empty repositories with on branches.
  - SVN tries to connect to an invalid remote.
  - None of them set the INIT repo flag correctly, so status doesn't get updated properly in the UI.

Fix all this stuff.

Test Plan:
  - For each of Git, SVN and Mercurial:
    - Created a new repository from the web UI in a deactivated state.
    - Made it hosted.
    - Manually ran pull/discover.
    - Verified we end up with initialized, empty repositories in consistent states.

d8bda7c66e Add an "importing" state to repositories and clean up the UI
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:
