Fixes T13031. "Enormous" changes are basically changes which are too large to hold in memory, although the actual definition we use today is "more than 1GB of change text or `git diff` runs for more than 15 minutes".
If an install configures a Herald content rule like "when content matches /XYZ/, do something" and then a user pushes a 30 GB source file, we can't put it into memory to `preg_match()` it. Currently, the way to handle this case is to write a separate Herald rule that rejects enormous changes. However, this isn't obvious and means the default behavior is unsafe.
Make the default behavior safe by rejecting these changes with a message, similar to how we reject "dangerous" changes (which permanently delete or overwrite history) by default.
Also, change a couple of UI strings from "Enormous" to "Very Large" to reduce ambiguity. See <https://discourse.phabricator-community.org/t/herald-enormous-check/822>.
Test Plan: Changed the definition of "enormous" from 1GB to 1 byte. Pushed a change; got rejected. Allowed enormous changes, pushed, got rejected by a Herald rule. Disabled the Herald rule, pushed, got a clean push. Prevented enormous changes again. Grepped for "enormous" elsewhere in the UI.

Summary:
Ref PHI109. Ref T11786. We currently test elapsed time every 64 iterations (since iterations are normally very fast), but at least one install is seeing the page timeout after 30 seconds.
One reason could be that cache fills may occur, and are likely to be much slower than normal iterations. In an extreme case, we could do 64 cache fills before checking the time. Tweak thing so that we always check the time after doing a cache fill, regardless of how many iterations have elapsed since the last attempt.
Additionally, this API method currently accepts an arbitrary number of paths, but implicitly limits each cache query to 500ms. If more than 60 paths are passed, this may exceed 30s. Only let the cache churn for a maximum of 10s across all paths.
If this is more the latter issue than the former, this might replace the GraphCache timeouts with `git` timeouts, but at least our understanding of what's going on here will improve.

Summary:
Ref T11823. Currently, we have a "RefCursor" table which stores rows like `<branch or tag name, commit it is pointing at>` with some more data.
Because Mercurial can have a single branch pointing at several different places, this table must allow multiple rows with the same branch or tag name.
Among other things, this means there isn't a single PHID which can be used to identify a branch name in a stable way. However, we have several UIs where we want to be able to do this.
Some specific examples where we run into trouble: in Mercurial, if there are 5 heads for "default", that means there are 5 phids. And currently, if someone deletes a branch, we lose the PHID for it. Instead, we'd rather retain it so the whole world doesn't break if you accidentally delete a branch and then fix it a little later.
(I'll likely hold this until the rest of the logic is fleshed out a little more in followup changes.)

Summary:
Via HackerOne (<https://hackerone.com/reports/220909>). When we close commits in response to "Fixes Txxx", we currently act as the omnipotent user. This allows users to close tasks they can't see by pushing commits with "Fixes Txxx" in the message.
However, we can't actually tell who authored or committed a change: we're just using the "Author" and "Committer" values from Git in most cases, and anyone can forge those. So we can't really get this right, in a security sense.
(We can tell who //pushed// a change if we host it, but that's often not the right user. If GPG signing was more prevalent, we could use that. In the future, we could use side channels like having `arc land` tell Phabrcator who was pushing changes.)
Since I think the impact of this is fairly minor and this isn't //really// a security issue (more of a confusion/abuse/product issue) I think the behavior is okay more-or-less as-is, but we can do better when we do identify an author: drop permissions, and use their privileges to load the tasks which the commit "fixes".
This effectively implements this rule:
> If we identify the author of a commit as user X, that commit can only affect tasks which user X can see and edit.
Note that:
- Commits which we can't identify the author for can still affect any task.
- Any user can forge any other user's identity (or an invalid identity) and affect any task.
So this is just a guard rail to prevent mistakes by good-faith users who type the wrong task IDs, not a real security measure.
Also note that to perform this "attack" you must already have commit access to a repository (or permission to create a repository).
Test Plan:
- Used `bin/repository reparse --message <commit> --force-autoclose` to run the relevant code.
- Made the code `throw` before it actually applied the edit.
- Verified that the edit was rejected if the author was recognized and can not see or could not edit the task.
- Verified that the edit is accepted if the author can see+edit the task.
- Verified that the edit is accepted if we can't figure out who the author is.

- Try a fetch.
- If that fails, try repairing the origin URI.
- Then try again.
This is pretty complicated, and we can use this simpler logic instead:
- Set the origin URI to the right value.
- Try a fetch.
Setting the origin URI is very fast. This can normally only get us in any trouble in very obscure situations which haven't occurred for many years:
- Pretty much all of this is already covered by `verifyGitOrigin()`, which we run earlier.
- Origins could be configured to have multiple URIs for some reason, but shouldn't be.
- Years ago, you could configure Phabricator to point at a local repository it didn't own and that could conceivably have a different "origin" that you might not want us to delete. If you did this, the daemons have been spewing errors for 3-4 years without you fixing it. The cost of fixing the remote URI is very small even if anyone is affected by this (just set it back to the old value) and there's zero reason to do this and the scenario is ridiculous.

Summary:
Ref T12296. Ref T12392. Currently, when we're observing a remote repository, we periodically run `git fetch ...`.
Instead, periodically run `git ls-remote` (to list refs in the remote) and `git for-each-ref` (to list local refs) and only continue if the two lists are different.
The motivations for this are:
- In T12296, it appears that doing this is //faster// than doing a no-op `git fetch`. This effect seems to reproduce locally in a clean environment (900ms for `ls-remote` + 100ms for `for-each-ref` vs about 1.4s for `fetch`). I don't have any explanation for why this is, but there it is. This isn't a huge change, although the time we're saving does appear to mostly be local CPU time, which is good for us.
- Because we control all writes, we could cache `git for-each-ref` in the future and do fewer disk operations. This doesn't necessarily seem too valuable, though.
- This allows us to tell if a fetch will do anything or not, and make better decisions around clustering (in particular, simplify how observed repository versioning works). With `git fetch`, we can't easily distinguish between "fetch, but nothing changed" and "legitimate fetch".
If a repository updates very regularly we end up doing slightly more work this way (that is, if `ls-remote` always comes back with changes, we do a little extra work), but this is normally very rare.
This might not get non-bare repositories quite right in some cases (i.e., incorrectly detect them as changed when they are unchanged) but we haven't created non-bare repositories for many years.
Test Plan: Ran `bin/repository update --trace --verbose PHABX`, saw sensible construction of local and remote maps and accurate detection of whether a fetch would do anything or not.

When we miss the cache, we need to single-get refs to check them, which is relatively expensive.
Increasing the size of the cache to 65535 should only require about 7.5MB of RAM.
Additionally, fill only as much of the cache as actually fits. The FIFO nature of the cache can get us into trouble otherwise.
If we insert "A, B, C, D" and then lookup A, B, C, D, but the cache has maximum size 3, we get this:
- Insert A, B, C, D: cache is now "B, C, D".
- Lookup A: miss, single get, insert, purge, cache is now "C, D, A".
- Lookup B: miss, singel get, insert, purge, cache is now "D, A, B".
Test Plan:
- Reduced cache size to 5, observed reasonable behavior on the `array_slice()` locally with `bin/repository update` + `var_dump()`.
- Used this script to estimate the size of 65535 cache entries as 7.5MB:

I'll issue guidance on this but I'm not migrating it, since it fixes itself going forward and only really affects the UI in Owners.
Test Plan:
- Ran `bin/audit update-owners` with various arguments.
- Viewed packages in web UI, saw them load the proper commits.
- Queried by packages in Diffusion explicitly.
- Clicked the "View All" link in Owners and got to the right search UI.

This still isn't perfect and it should probably live in a Query or something some day, but there's some weird stuff going on with the viewer in the editor context, and at least the code handles the viewer correctly now and isn't living somewhere weird and totally unrelated to auditing, and the callsites don't need to do a bunch of extra work.
This also moves towards fixing the "re-accept if you've already accepted but then a new package you have authority over was added" bug, which we fixed recently in Differential. This should be less common in Audit, but should still be fixed.

Fixes T12087. When transitioning into a clustered configuration for the first time, the documentation recommends using a one-device cluster as a transitional step.
However, installs may not do this for whatever reason, and we aren't as clear as we could be in warning about clusterizing directly into a multi-device cluster.
Roughly, when you do this, we end up believing that working copies exist on several different devices, but have no information about which copy or copies are up to date. //Usually// they all were already synchronized and are all up to date, but we can't make this assumption safely without risking data.
Instead, we err on the side of caution, and require a human to tell us which copy we should consider to be up-to-date, using `bin/repository thaw --promote`.
Test Plan:
```
$ ./bin/repository clusterize rLOCKS --service repos001.phacility.net
Service "repos001.phacility.net" is actively bound to more than one device
(local002.local, local001.phacility.net).
If you clusterize a repository onto this service it will be unclear which
devices have up-to-date copies of the repository. This leader/follower
ambiguity will freeze the repository. You may need to manually promote a
device to unfreeze it. See "Ambiguous Leaders" in the documentation for
discussion.

- We once published build updates to Revisions.
- An unrelated fix (D10911) sent them to the Diffs instead of Revisions, which isn't useful, since you can't see a diff's timeline anywhere.
- This also caused a race condition, where the RevisionEditor and DiffEditor would update the diff simultaneously (T8650).
- The diff update was just disabled to avoid the race (part of D13441).
- Instead, allow the updates to go somewhere else. In this case, we send commit updates to the commit but send diff updates to the revision so you can see 'em.
- Since everything will be using the revision editor now, we should either get proper lock behavior for free or it should be easy to add if something whack is still happening.
- Overall, this should pretty much put us back in working order like we were before D10911.

Summary:
Ref T11954. This is kind of complex and I'm not sure I want to actually land it, but it gives us a fairly good improvement for clustered repositories so I'm leaning toward moving forward.
When we make (or receive) clustered repository requests, we must first load a bunch of stuff out of Almanac to figure out where to send the request (or if we can handle the request ourselves).
This involves several round trip queries into Almanac (service, device, interfaces, bindings, properties) and generally is fairly slow/expensive. The actual data we get out of it is just a list of URIs.
Caching this would be very easy, except that invalidating the cache is difficult, since editing any binding, property, interface, or device may invalidate the cache for indirectly connected services and repositories.
To address this, introduce `PhabricatorCacheEngine`, which is an extensible engine like `PhabricatorDestructionEngine` for propagating cache updates. It has two modes:
- Discover linked objects (that is: find related objects which may need to have caches invalidated).
- Invalidate caches (that is: nuke any caches which need to be nuked).
Both modes are extensible, so third-party code can build repository-dependent caches or whatever. This may be overkill but even if Almanac is the only thing we use it for it feels like a fairly clean solution to the problem.
With `CacheEngine`, make any edit to Almanac stuff propagate up to the Service, and then from the Service to any linked Repositories.
Once we hit repositories, invalidate their caches when Almanac changes.
Test Plan:
- Observed a 20-30ms performance improvement with `ab -n 100`.
- (The main page making Conduit calls also gets a performance improvement, although that's a little trickier to measure directly.)
- Added debugging code to the cache engine stuff to observe the linking and invalidation phases.
- Made invalidation throw; verified that editing properties, bindings, etc, properly invalidates the cache of any indirectly linked repositories.

- The first step ("Message") now queues at a slightly-lower-than-default (for already-imported repositories) or very-low (for newly importing repositories) priority level.
- The other steps now queue at "default" priority level. This is actually what they already did, but without this change their behavior would be to inherit the priority level of their parents.
This has two effects:
- When adding new repositories to an existing install, they shouldn't block other things from happening anymore.
- The daemons will tend to start one commit and run through all of its steps before starting another commit. This makes progress through the queue more even and predictable.
- Before, they did ALL the message tasks, then ALL the change tasks, etc. This works fine but is confusing/uneven/less-predictable because each type of task takes a different amount of time.

Ref T11665. Currently, when a repository hits an error, we retry it after 15s. This is correct if the error was temporary/transient/config-related (e.g., bad network or administrator setting up credentials) but not so great if the error is long-lasting (completely bad authentication, invalid URI, etc), as it can pile up to a meaningful amount of unnecessary load over time.
Instead, record how many times in a row we've hit an error and adjust backoff behavior: first error is 15s, then 30s, 45s, etc.
Additionally, when computing the backoff for an empty repository, use the repository creation time as though it was the most recent commit. This is a good proxy which gives us reasonable backoff behavior.
This required removing the `CODE_WORKING` messages, since they would have reset the error count. We could restore them (as a different type of message), but I think they aren't particularly useful since cloning usually doesn't take too long and there's more status information avilable now than there was when this stuff was written.

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.)

- They intereted the internal ID number of a commit to mean that Phabricator was malfunctioning.
Make the language of this condition more direct, explaining what the situation means in greater detail.
Additionally, we would previously re-throw this exception, which would make the daemon exit, wait a moment, and restart. This was normal and expected.
When //unexpected// failures occur, it's important do to this: it prevents a daemon failing in a loop from causing too many side effects (e.g., limit of 1 email per 5 seconds instead of thousands per second).
When expected, permanent failures occur, we do not need to do this: the task will not be retried. I just did it because it was slightly more consistent ("failures restart daemons") and we had few permanent failure types at the time.
We have more now, and restarting the daemons generates some additional logs which have the potential to confuse. Cycling the daemon also (intentionally) reduces the rate at which we process tasks, which can be bad for permanent failures like "deleted commit" because users can delete a huge number of commits and possibly clog up the queue with cycle-after-failure actions.
Test Plan:
Tried to process a deleted commit, saw a new message:
```

Fixes T11269. The basic issue is that `git log` in an empty repository exits with an error message.
Prior to recent Git (2.6?), this message reads:
> fatal: bad default revision 'HEAD'
This message was somewhat recently changed by <ce11360467>. After that, it reads:
> fatal: your current branch 'master' does not have any commits yet
This change isn't //technically// a //complete// fix because you could still hit this issue like this:
- Create an empty repository.
- Push some stuff to `master`.
- Delete `master`.
However, this is very rare and even in this case the repository will fix itself once you push something again. We can try to fix that if any users ever actually hit it.
Test Plan:
- Created a new empty Git repository.
- Ran `bin/repository update Rxx`.
- Before patch: "git log" error because of the empty repository.
- After patch: clean update.
- Also ran `repository update` on a non-empty repository.

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".

Ref T9028. This allows us to detect when commits are unreachable:
- When a ref (tag, branch, etc) is moved or deleted, store the old thing it pointed at in a list.
- After discovery, go through the list and check if all the stuff on it is still reachable.
- If something isn't, try to follow its ancestors back until we find something that is reachable.
- Then, mark everything we found as unreachable.
- Finally, rebuild the repository summary table to correct the commit count.
Test Plan:
- Deleted a ref, ran `pull` + `refs`, saw oldref in database.

Summary:
Ref T9028. This improves the daemon behavior for unreachable commits. There is still no way for commits to become marked unreachable on their own.
- When a daemon encounters an unreachable commit, fail permanently.
- When we revive a commit, queue new daemons to process it (since some of the daemons might have failed permanently the first time around).
- Before doing a step on a commit, check if the step has already been done and skip it if it has. This can't happen normally, but will soon be possible if a commit is repeatedly deleted and revived very quickly.
- Steps queued with `bin/repository reparse ...` still execute normally.
Test Plan:
- Used `bin/repository reparse` to run every step, verified they all mark the commit with the proper flag.
- Faked the `reparse` exception in the "skip step" code, used `repository reparse` to skip every step.
- Marked a commit as unreachable, ran `discover`, saw daemons queue for it.
- Ran daemons with `bin/worker execute --id ...`, saw them all skip + queue the next step.

- Ran `repository discover --trace --verbose`.
- Saw the discovery process ignore the commit when filling the cache.
- Saw the discovery process revive the commit instead of trying to record it again.

Summary:
Ref T9028. Fixes T6878. Currently, we only fetch and discover branches. This is fine 99% of the time but sometimes commits are pushed to just a tag, e.g.:
```
git checkout <some hash>
nano file.c
git commit -am '...'
git tag wild-wild-west
git push origin wild-wild-west
```
Through a similar process, commits can also be pushed to some arbitrary named ref (we do this for staging areas).
With the current rules, we don't fetch tag refs and won't discover these commits.
Change the rules so:
- we fetch all refs; and
- we discover ancestors of all refs.
Autoclose rules for tags and arbitrary refs are just hard-coded for now. We might make these more flexible in the future, or we might do forks instead, or maybe we'll have to do both.
Test Plan:
Pushed a commit to a tag ONLY (`vegetable1`).
<cf508b8de6>
On `master`, prior to the change:
- Used `update` + `refs` + `discover`.
- Verified tag was not fetched with `git for-each-ref` in local working copy and the web UI.
- Verified commit was not discovered using the web UI.
With this patch applied:
- Used `update`, saw a `refs/*` fetch instead of a `refs/heads/*` fetch.
- Used `git for-each-ref` to verify that tag fetched.
- Used `repository refs`.
- Saw new tag appear in the tags list in the web UI.
- Saw new refcursor appear in refcursor table.
- Used `repository discover --verbose` and examine refs for sanity.
- Saw commit row appear in database.
- Saw commit skeleton appear in web UI.
- Ran `bin/phd debug task`.

`PhutilURI` now attempts to "just work" with Git-style URIs, so at least in theory we can just delete all of this code and pretend it does not exist.
(I've left "Display URI" and "Effective URI" as distinct, at least for now, because I think the distinction may be relevant in the future even though it isn't right now, and to keep this diff small, although I may go remove one after I think about this for a bit.)
Test Plan:
- Created a new Git repository with a Git URI.
- Pulled/updated it, which now works correctly and should resolve the original issue in T11137.
- Verified that daemons now align the origin to a Git-style URI with a relative path, which should resolve the original issue in T11004.

Summary:
Ref T4292. For hosted, clustered repositories we have a good way to increment the internal version of the repository: every time a user pushes something, we increment the version by 1.
We don't have a great way to do this for observed/remote repositories because when we `git fetch` we might get nothing, or we might get some changes, and we can't easily tell //what// changes we got.
For example, if we see that another node is at "version 97", and we do a fetch and see some changes, we don't know if we're in sync with them (i.e., also at "version 97") or ahead of them (at "version 98").
This implements a simple way to version an observed repository:
- Take the head of every branch/tag.
- Look them up.
- Pick the biggest internal ID number.
This will work //except// when branches are deleted, which could cause the version to go backward if the "biggest commit" is the one that was deleted. This should be OK, since it's rare and the effects are minor and the repository will "self-heal" on the next actual push.
Test Plan:
- Created an observed repository.
- Ran `bin/repository update` and observed a sensible version number appear in the version table.
- Pushed to the remote, did another update, saw a sensible update.
- Did an update with no push, saw no effect on version number.
- Toggled repository to hosted, saw the version reset.
- Simulated read traffic to out-of-sync node, saw it do a remote fetch.

- Packages with auditing disabled ("NONE" audits).
- Packages with auditing enabled, but they don't need an audit (e.g., author is a pacakge owner; "NOT REQUIRED" audits).
These audits aren't interesting (we only write them so we can list "commits in this package" from other UIs) but right now they take up the audit slot. In particular:
- They show in the UI, but are generally useless/confusing nowadays. The actual table of contents does a better job of just showing "which packages do these paths belong to" now, and shows all packages for each path.
- They block Herald from adding real auditors.
Change this:
- Don't show uninteresting auditors.
- Let Herald upgrade uninteresting auditors into real auditors.
