- We could do an older TYPE_ACTION "close" via the daemons.
- We could do an older TYPE_ACTION "close" via `arc close-revision`, explicitly or implicitly in `arc land`, via API (`differential.close`).
- We could do an older TYPE_ACTION "rethink" ("Plan Changes") via the API, via `arc diff --plan-changes` (`differential.createcomment`).
Move these to modern modular transactions, then get rid of all the validation and application logic for them. This nukes a bunch of `ArcanistDifferentialRevision::...` junk.

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.

Ref T12392. The logic currently goes like this:
- 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.

Ref T12296. This cache is used to cache Git ref heads (branches, tags, etc). Reasonable repositories may have more than 2048 of these.
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:
```

<?php
$cache = array();
$mem_start = memory_get_usage();

Instead, write an explicit edge which just says "this commit is part of such-and-such packages". Then use that to run the query. Logical!

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

- 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.

- Following the process in T11537#192019, artificially created a commit with //no// date information (I deleted all date information from the message).
- Used `git show` / `git log --format ...` to inspect it: "Jan 1, 1970" on `git show`, no information at all on `%aD`, `%aT`, etc.
- Pushed it.
- Saw exception for trying to insert empty string into epoch colum from `bin/repository update`.
- Applied patch.
- Got a clean import.

Summary:
Fetches cause output in `/var/tmp/phd/log/daemons.log` as
follows:
```
PHLOG: 'Unexpected output while updating repository "rREPONAME": No entry for terminal type "unknown";
using dumb terminal settings.
' at [/path/to/phabricator/src/applications/repository/daemon/PhabricatorRepositoryPullLocalDaemon.php:455]
```
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.
Test Plan:
Enabled in production, observed errors to be silenced and
no SSH hangs

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.

Summary:
Fixes T11940. In 2.11.0, Git has made a change so that newly-pushed changes are held in a temporary area until the hook accepts or rejects them.
This magic temporary area is only readable if the appropriate `GIT_ENVIRONMENTAL_MAGIC` variables are available. When executing `git` commands, pass them through from the calling context.
We're intentionally conservative about which variables we pass, and with good reason (see "httpoxy" in T11359). I think this continues to be the correct default behavior.
Test Plan:
- Upgraded to Git 2.11.0.
- Tried to push over SSH, got a hook error.
- Applied patch.
- Pulled and pushed over SSH.
- Pulled and pushed over HTTP.
