Currently, if `@alice` resigns from a revision but `#alice-fan-club` is still a subscriber or reviewer, she'll continue to get mail. This is undesirable.
When users are associated with an object but have explicitly disengaged in an individal role (currently, only resign in audit/differential) mark them "unexpandable", so that they can no longer be included through implicit membership in a group (a project or package).
`@alice` can still get mail if she's a explicit recipient: as an author, owner, or if she adds herself back as a subscriber.
Test Plan:
- Added `@ducker` and `#users-named-ducker` as reviewers. Ducker got mail.
- Resigned as ducker, stopped getting future mail.
- Subscribed explicitly, got mail again.

Summary:
Depends on D19009. Ref T13053. For "Must Encrypt" mail, we must currently strip the "Thread-Topic" header because it sometimes contains sensitive information about the object.
I don't actually know if this header is useful or anyting uses it. My understanding is that it's an Outlook/Exchange thing, but we also implement "Thread-Index" which I think is what Outlook/Exchange actually look at. This header may have done something before we implemented "Thread-Index", or maybe never done anything. Or maybe older versions of Excel/Outlook did something with it and newer versions don't, or do less. So it's possible that an even better fix here would be to simply remove this, but I wasn't able to convince myself of that after Googling for 10 minutes and I don't think it's worth hours of installing Exchange/Outlook to figure out. Instead, I'm just trying to simplify our handling of this header for now, and maybe some day we'll learn more about Exchange/Outlook and can remove it.
In a number of cases we already use the object monogram or PHID as a "Thread-Topic" without users ever complaining, so I think that if this header is useful it probably isn't shown to users, or isn't shown very often (e.g., only in a specific "conversation" sub-view?). Just use the object PHID (which should be unique and stable) as a thread-topic, everywhere, automatically.
Then allow this header through for "Must Encrypt" mail.
Test Plan: Processed some local mail, saw object PHIDs for "Thread-Topic" headers.

Removes the "self" stamps, since you can just write a rule against `whatever(@epriestley)` equivalently. If there's routing logic around this, it can live in the routing layer. This avoids tons of self-actor, self-mention, self-reviewer, self-blocking-reviewer, self-resigned-reviewer, etc., stamps.
Use `natcasesort()` instead of `sort()` so that numeric values (like monograms) sort `9, 80, 700` instead of `700, 80, 9`.
Remove the commas from rendering since they don't really add anything.

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.

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.

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.
Test Plan: Ran `bin/repository update PHABX --trace --verbose`, saw fetches go through cleanly after URI adjustment.

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:

- After D17264, we no longer need the "AUDIT_NOT_REQUIRED" fake-audits to record package membership. This no longer creates them.
- This previously saved English-language, untranslatable text strings about audit details onto the audit relationship. I've removed them, per discussion in D17263.
The "Audit Reasons" here are potentially a little more useful than the Herald/Explicit-By-Owner ones were, since the rules are a little more complex, but I'd still like to see evidence that we need them.

This auditor is used to power the "Commits in this package" query in Owners.
This conflates audits and commit/package membership. I think it might even predate edges. Code needs to dance around this mess and we get the wrong result in some cases, since auditors are now editable.
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!
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.

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.

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 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.

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.)

Summary:
Fixes T10423. Ref T11524. This changes `diffusion.rawdiffquery` to return a file PHID instead of a blob of data.
This is better in general, but particularly better for huge diffs (as in T10423) and diffs with non-utf8 data (as in T10423).
Test Plan:
- Used `bin/differential extract` to extract a latin1 diff, got a clean diff.
- Used `bin/repository reparse --herald` to rerun herald on a latin1 diff, got a clean result.
- Pushed latin1 diffs to test commit hooks.
- Triggered the the too large / too slow logic.
- Viewed latin1 diffs in Diffusion.
- Used "blame past this change" in Diffusion to hit the `before` logic.

Summary:
Fixes T11537. See that task for discussion.
Although we could accommodate these faithfully, it requires a huge migration and affects one repository on one install which was written with buggy tools.
At least for now, just replace out-of-32-bit-range epoch values with the current time, which is often somewhat close to the real value.
Test Plan:
- Following the instructions in T11537, created commits in 40,000 AD.
- Tried to import them, reproducing the "epoch" database issue.
- Applied the patch.
- Successfully imported future-commits, with some liberties around commit dates. Note that author date (not stored in an `epoch` column) is still shown faithfully:

Summary:
Ref T11522. This tries to reduce the cost of rewriting a repository by making handles smarter about rewritten commits.
When a handle references an unreachable commit, try to load a rewrite hint for the commit. If we find one, change the handle name to "OldHash > NewHash" to provide a strong hint that the commit was rewritten and that copy/pasting the old hash (say, to the CLI) won't work.
I think this notation isn't totally self-evident, but users can click it to see the big error message on the page, and it's at least obvious that something weird is going on, which I think is the important part.
Some possible future work:
- Not sure this ("Recycling Symbol") is the best symbol? Seems sort of reasonable but mabye there's a better one.
- Putting this information directly on the hovercard could help explain what this means.

Ref T11522. When a commit is no longer reachable from any branch/tag, we currently show a "this has been deleted" message.
Instead, go further: check if there is a "rewritten" hint pointing at a commit the current commit was rewritten into. If we find one, show a message about that instead.
(This isn't super pretty, just getting it working for now. I expect to revisit this UI in T9713 if we don't get to it before that.)

Ref T11522. This provides storage for tracking rewritten commits (new feature) and unreadable commits (existing feature, but really hacky).
This doesn't do anything yet, just adds a table and a CLI tool for updating it. I'll document the tool once it works. You just pipe in some JSON, but I need to document the format.
Test Plan:
- Piped JSON for "none", "rewritten" and "unreadable" hints into `bin/repository hint`.
- Examined the database to see that the table was written properly.
- Tried to pipe bad JSON in, invalid hint types, etc. Got reasonable human-readable error messages.

Summary:
Fixes T11453. Currently, commit message summaries are limited to 80 bytes. This may only be 20-40 characters for CJK languages or langauges with Cyrillic script.
Increase storage size to 255, then truncate to the shorter of 255 bytes or 80 glyphs. This preserves the same behavior for latin languages, but is less tight for Russian, etc.
Some minor additional changes:
- Provide a way to ask "how much data fits in this column?" so we don't have to duplicate column lengths across summary checks or UI errors like "title too long".
- Remove the `text80` datatype, since no other columns use it and we have no use cases (or likely use cases) for it.
Test Plan:
- Made a commit with a Cyrillic title, saw reasonable summarization in UI:
{F1757522}
- Added and ran unit tests.
- Grepped for removed `SUMMARY_MAX_LENGTH` constant.
- Grepped for removed `text80` data type.

Summary:
Fixes T11309. When checking if a repository was fully imported, we incorrectly allow unreachable, un-imported commits to prevent the repository from moving to "Imported".
This can happen if you delete branches from a repository while it is importing.
Instead, ignore unreachable commits when checking for remaining imports, and when reporting status via `bin/repository importing`.
Test Plan:
- Stopped daemons.
- Created a new repository and activated it.
- Ran `bin/repository update Rxx`.
- Deleted a branch in the repository.
- Ran `bin/repository update Rxx`.
- Ran daemons to flush queue.
Now:
- Ran `bin/repository importing`. Old behavior: showed unreachable commits as importing. New behavior: does not show unreachable commits.
- Ran `bin/repository update`. Old behavior: failed to move repository to "imported" status. New behavior: correctly moves repository to "imported" status.

Summary:
Ref T11309. In that task, a user misunderstood two parts of this error:
- They took "exception" to mean "unexpected failure", when it was intended to mean "rare circumstance".
- 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:
```

This usually means that the branch the commit was on was deleted or overwritten.

Summary:
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.
