Ref T13202. See PHI889. If the lock log is enabled, we can try to offer more details about lock holders.
When we fail to acquire a lock:
- check for recent acquisitions and suggest that this is a bottleneck issue;
- if there are no recent acquisitions, check for the last acquisition and print details about it (what process, how long ago, whether or not we believe it was released).
Test Plan:
- Enabled the lock log.
- Changed the lock wait time to 1 second.
- Added a `sleep(10)` after grabbing the lock.
- In one window, ran a Conduit call or a `git fetch`.
- In another window, ran another operation.

Summary:
Ref T13142. When commits are pushed, we try to handle them on one of two pathways:
- Normal changes: we load these into memory and potentially apply Herald content rules to them.
- "Enormous" changes: we don't load these into memory and skip content rules for them.
The goal is to degrade gracefully when users push huge changes: they should work, just not support all the features.
However, some changes can slip through the cracks right now:
- If you push a lot of commits at once, we'll try to cache all of the changes smaller than 1GB in memory. This can require an arbitrarily large amount of RAM.
- We calculate sizes by just looking at the `strlen()` of the diff, but a changeset takes more RAM in PHP than the raw diff does. So even if a diff is "only" 500MB, it can take much more memory than that. On systems with relatively little memory available, this may result in OOM while processing changes that are close to the "enormous" limit.
This change makes two improvements:
- Instead of caching everything, cache only 64MB of things.
- For most pushes, this is the same, since they have less than 64MB of diffs.
- For pushes of single very large changes, this is a bit slower (more CPU) since we have to do some work twice.
- For pushes of many changes, this is slower (more CPU) since we have to do some work twice, but, critically, doesn't require unlimited memory.
- Instead of flagging changes as "enormous" at 1GB, flag them as "enormous" at 256MB.
- This reduces how much memory is required to process the largest "non-enormous" changes.
- This also gets us under Git's hard-coded 512MB "always binary" cutoff; see T13143.
- This is still completely gigantic and way larger than any normal change should be.
An additional improvement would be to try to reduce the amount of memory we need to use to hold a change in process memory. I think the other changes here alone will fix the immediate issue in PHI657, but it would be nice if the "largest non-enormous change" required only a couple gigs of RAM.
Test Plan:
- Used `ini_set('memory_limit', '1G')` to artificially limit memory to 1GB.
- Pushed a series of two commits which add two 550MB text files (Temporarily, I added a `--binary` flag to trick Git into showing real diffs for these, see T13143.)
- Got a memory limit error.
- Applied the "cache only 64MB of stuff" and "consider 256MB, not 1GB, to be enormous" changes.
- Pushed again, got properly rejected as enormous.
- Added `memory_get_usage()` calls to measure how actual memory size and reported "size" estimate compare. For these changes, saw a 639MB diff require 31,479MB of memory, i.e. a factor of about 50x. This is, uh, pretty not great.
- Allowed enormous changes, pushed again, push went through.

Summary:
Ref T13110. Currently, build status is published the same way for every Buildable by the BuildEngine.
I want to change this to delegate publishing to each Buildable, particularly so that Differential may use more detailed rules for handling builds and drafts.
Rather than add additional methods to the existing `BuildableInterface`, add an engine generator method instead. This is a pattern which has seen more use recently (e.g., in Ferret) and lets us pay a little more upfront to pull complex pieces of logic out of the main class and let them use inheritence more easily.

I'd expect to eventually reduce the size of `BuildableInterface` and move the `CircleCI` and `BuildKite` interfaces so that the `BuildableEngine` implements them instead of the main object.

We can't currently implement a strict `form-action 'self'` content security policy because some file downloads rely on a `<form />` which sometimes POSTs to the CDN domain.
Broadly, stop generating these forms. We just redirect instead, and show an interstitial confirm dialog if no CDN domain is configured. This makes the UX for installs with no CDN domain a little worse and the UX for everyone else better.
Then, implement the stricter Content-Security-Policy.
This also removes extra confirm dialogs for downloading Harbormaster build logs and data exports.

Ref T13083. Facts has a fair amount of weird hardcoding and duplication of responsibilities. Reduce this somewhat: no more hard-coded fact aggregates, no more database-driven list of available facts, etc. Generally, derive all objective truth from FactEngines. This is more similar to how most other modern applications work.
For clarity, hopefully: rename "FactSpec" to "Fact". Rename "RawFact" to "Datapoint".
Split the fairly optimistic "RawFact" table into an "IntDatapoint" table with less stuff in it, then dimension tables for the object PHIDs and key names. This is primarily aimed at reducing the row size of each datapoint. At the time I originally wrote this code we hadn't experimented much with storing similar data in multiple tables, but this is now more common and has worked well elsewhere (CustomFields, Edges, Ferret) so I don't anticipate this causing issues. If we need more complex or multidimension/multivalue tables later we can accommodate them. The queries a single table supports (like "all facts of all kinds in some time window") don't make any sense as far as I can tell and could likely be UNION ALL'd anyway.
Remove all the aggregation stuff for now, it's not really clear to me what this should look like.

This sort of makes sense, but is also sort of weird. Particularly, I think it's kind of hard to understand and predict, and hard to guess that this is the behavior we implement. The actual implementation is complex, too.
Instead, just use the rule "administrators can see remote addresses" consistently across all applications. This should generally be more strict than the old rule, because administrators could usually have seen everyone's address in the activity logs anyway. It's also simpler and more expected, and I don't really know of any legit use cases for the "repository editor" rule.

Allow SearchEngine implementations to define exportable fields so that users can "Use Results > Export Data" on any query. In particular, they can use this workflow to download a file with pull logs.
In the future, this can replace the existing "Export to Excel" feature in Maniphest.
For now, we hard-code JSON as the only supported datatype and don't actually make any effort to format the data properly, but this leaves room to add more exporters (CSV, Excel) and data type awareness (integer casting, date formatting, etc) in the future.
For sufficiently large result sets, this will probably time out. At some point, I'll make this use the job queue (like bulk editing) when the export is "large" (affects more than 1K rows?).

The SSH workflows currently extend `PhabricatorManagementWorkflow` to benefit from sharing all the standard argument parsing code. Sharing the parsing code is good, but it also means they inherit a `getViewer()` method which returns the ommnipotent viewer.
This is appropriate for everything else which extends `ManagementWorkflow` (like `bin/storage`, `bin/auth`, etc.) but not appropriate for SSH workflows, which have a real user.
This caused a bug with the pull logs where `pullerPHID` was not recorded properly. We used `$this->getViewer()->getPHID()` but the correct code was `$this->getUser()->getPHID()`.
To harden this against future mistakes:
- Don't extend `ManagementWorkflow`. Extend `PhutilArgumentWorkflow` instead. We **only** want the argument parsing code.
- Rename `get/setUser()` to `get/setSSHUser()` to make them explicit.
Then, fix the pull log bug by calling `getSSHUser()` instead of `getViewer()`.

- When we finish reading `git cat-file ...` or whatever, we can end up with more than one chunk worth of bytes left in the internal buffer if the read is fast. Use `while` instead of `if` to make sure we write the whole buffer.
- Limiting output with `setStdoutSizeLimit()` isn't really a reliable way to limit the size if we're also reading from the buffer. It's also pretty indirect and confusing. Instead, just let the `FileUploadSource` explicitly implement a byte limit in a straightforward way.
- We weren't setting the time limit correctly on the main path.
Overall, this could cause >4MB files to "write" as 4MB files, with the rest of the file left in the UploadSource buffer. Since these files were technically under the limit, they could return as valid. This was intermittent.

Summary:
Ref T13036. This code attempts to filter the "capabilities" message to remove "bundle2", but I think this has never worked.
Specifically, the //write// pathway is hooked, and "write" here means "client is writing a message to the server". However, the "capabilities" frame is part of the response, not part of the request. Thus, this code never fires, at least on recent versions of Mercurial.
Since I plan to support bundle2 and don't want to decode response frames, just get rid of this, assuming we'll achieve those goals.
I think this was just overlooked in D14241, which probably focused on the HTTP version. This code does (at least, potentially) do something for HTTP.
I'm leaving the actual "strip stuff" code in place for now since I think it's still used on the HTTP pathway.
Test Plan:
- Added debug logging, saw this code never hit even though `hg push --debug` shows the client believing bundle2 is supported.
- Logged both halves of the wire protocol and saw this come from the server, not the client.
- Ran the failing `hg push` of a 4MB file under hg 4.4.1, got the same error as before.

Summary:
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:
See PHI262. Fixes T12578. Although this is a bit niche and probably better accomplished through advisory/soft measures ("Add blocking reviewers") in most cases, it isn't difficult to implement and doesn't create any technical or product tension.
If installs write a rule that blocks commits, that will probably also naturally lead them to an "add reviewers" rule anyway.
Also, allow packages to be hit with the typeahead. They're valid reviewers but previously you couldn't write rules against them, for no actual reason.
Test Plan: Used test console to run this against commits, got sensible results for the field value.

Summary: Ref T13030. See PHI254. This behavior could be cleaner than I've made it, but it fixes the "this is totally broken" issue, replacing a fatal/exception with an informative (just not terribly useful) page.
Test Plan:
- Added a submodule to a repository.
- In Diffusion, clicked some other file next to the submodule, then edited the URI to the submodule path instead.
- Before patch: fatal.
- After patch: relatively useful message about this being a submodule.
Note that it's normally hard to hit this URI directly. In the browse view, submodules are marked up as directories and linked to a separate submodule resolution flow.
