9777c66576 Allow Phabricator to run with "enable_post_data_reading" disabled
Summary:
Ref T13008. Depends on D18701. The overall goal here is to make turning `enable_post_data_reading` off not break things, so we can run rate limiting checks before we read file uploads.

The biggest blocker for this is that turning it off stops `$_FILES` from coming into existence.

This //appears// to mostly work. Specifically:

  - Skip the `max_post_size` check when POST is off, since it's meaningless.
  - Don't read or scrub $_POST at startup when POST is off.
  - When we rebuild REQUEST and POST before processing requests, do multipart parsing if we need to and rebuild FILES.
  - Skip the `is_uploaded_file()` check if we built FILES ourselves.

This probably breaks a couple of small things, like maybe `__profile__` and other DarkConsole triggers over POST, and probably some other weird stuff. The parsers may also need more work than they've received so far.

I also need to verify that this actually works (i.e., lets us run code without reading the request body) but I'll include that in the change where I update the actual rate limiting.

Test Plan:
  - Disabled `enable_post_data_reading`.
  - Uploaded a file with a vanilla upload form (project profile image).
  - Uploaded a file with drag and drop.
  - Used DarkConsole.
  - Submitted comments.
  - Created a task.
  - Browsed around.

821c7ac833 For backup persitsence, mark the "common ngrams" table as a data table, not an index table
Summary:
Ref T13000. Garbage collecting common ngrams is slow because MySQL isn't all that great at deleting rows quickly. See PHI96, where it looks like it's going to take a week to GC ngrams for a ~million objects at a relatively conservative 0.15 threshold.

In the event of a restore, we can reduce the impact by persisting this table so the ngrams just don't get built when the reindex happens.

Test Plan: Viewed schema in Config, saw common ngrams tables marked as "Data" instead of "Index".

85011a46d0 Bail out of PhabricatorRepositoryGraphCache more aggressively after cache fills
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.

Test Plan: This is difficult to test convincingly locally, since I can't reproduce the original issue. It still works after these changes, but it worked fine before these changes too.

17e83b53d5 Add "bin/search query" for debugging query execution
Summary:
Ref T13000. Currently, queries can only be executed from the web UI, which requires logging in as a user. I really want to avoid doing that wherever we can, but being able to execute queries on an instance (and, particularly, see the ngrams and timings on the underlying lookups) would have been helpful in several cases.

Improve tooling a bit in advance of the "common ngrams" stuff going out since it seems likely that it will be useful if issues arise.

Test Plan: Ran `bin/search query --query ...`, got useful minimal output. Ran with `--trace` to get internals.

c767c971ca Add "persistence" types (data, cache, or index) to tables, and tweak what "storage dump" dumps
Summary:
Ref T13000. This marks each table as either "data" (normal data), "cache" (automatically rebuilt, no need to ever dump) or "index" (can be manually rebuilt).

By default, `bin/storage dump` dumps data and index tables, but not cache tables.

With `--no-indexes`, it dumps only data tables. Indexes can be rebuilt after a restore with `bin/search index --all ...`.

Test Plan:
  - Ran `--no-indexes` and normal dumps with `--trace`, verified that cache and index (former case) or cache only (latter case) tables were dumped with `--no-data`.
  - Verified dump has the same number of `CREATE TABLE` statements as before the changes.
  - Reviewed persistence tags in the web UI (note Ferret engine tables are "Index"):

02e1440ef2 Dump tables one at a time, rather than all at once
Summary:
Ref T13000. This allows us to be more selective about which tables we dump data for, to reduce the size of backups and exports. The immediate goal is to make large `ngrams` tables more manageable in the cluster, but this generally makes all backups and exports faster and easier.

Here, tables are dumped one at a time. A followup change will sometimes add the `--no-data` flag, to skip dumping readthrough caches and (optionally) rebuildable indexes.

Test Plan: Compared a dump from `master` and from this branch, found them to be essentially identical. The new dump has a little more header information in each section. Verified each contains the same number of `CREATE TABLE` statements.

3e589cdd73 Add a workflow for populating (or depopulating) the common ngrams table
Summary:
Depends on D18672. Ref T13000. This does an on-demand build of the common ngrams table.

Plan here is:

  - Push to `secure`.
  - Build the common ngrams table here.
  - See if stuff breaks?

If it looks okay on this dataset, we can build out the GC support and try it in production.

Test Plan:
  - Locally, my dataset has a bunch of `bin/lipsum` tasks with similar, common words.
  - Verified that ipsum terms now skip ngrams. For "lorem ipsum" search performance actually IMPROVED by skipping the ngrams table (12s to 9s).
  - Queried for normal terms, got very fast results using the ngram table, as normal.

1de130c9f5 Allow the Ferret engine to remove "common" ngrams from the index
Summary:
Ref T13000. This adds support for tracking "common" ngrams, which occur in too many documents to be useful as part of the ngram index.

If an ngram is listed in the "common" table, it won't be written when indexing documents, or queried for when searching for them.

In this change, nothing actually writes to the "common" table. I'll start writing to the table in a followup change.

Specifically, I plan to do this:

  - A new GC process updates the "common" table periodically, by writing ngrams which appear in more than X% of documents to it, for some value of X, if there are at least a minimum number of documents (maybe like 4,000).
  - A new GC process deletes ngrams that have been added to the common table from the existing indexes.

Hopefully, this will pare down the ngrams index to something reasonable over time without requiring any manual tuning.

Test Plan:
  - Ran some queries and indexes.
  - Manually inserted ngrams `xxx` and `yyy` into the ngrams table, searched and indexed, saw them ignored as viable ngrams for search/index.

5c73c169fd Rough cut of "Move tasks to column..."

Add a "Move tasks to column..." action to workboards which moves all visible tasks in a column to another column, either on the same board or on a different board.

This is a two-step process so that I don't have to write Javascript, and because I'm not 100% sure this is what users actually want/need. If it sticks, the UI could be refined later.

  - The first dialog asks you to choose a project, defaulting ot the current project.
  - The second dialog asks you to choose a column on that project's board.

9875af739f When we purge the request cache, also force PHP to collect cycles
Summary:
Ref T12997. See that task for more details. Briefly, an unusual dataset (where commits are mentioned hundreds of times by other commits) is causing some weird memory behavior in the daemons.

Forcing PHP to GC cycles explicitly after each task completes seems to help with this, by cleaning up some of the memory between tasks. A more thorough fix might be to untangle the `$xactions` structure, but that's significantly more involved.

Test Plan:
  - Did this locally in a controlled environment, saw an immediate collection of a 500MB `$xactions` cycle.
  - Put a similar change in production, memory usage seemed less to improve. It's hard to tell for sure that this does anything, but it shouldn't hurt.

086a125ad5 Improve performance of Ferret engine ngram extraction, particularly for large input strings
Summary:
See PHI87. Ref T12974. The `array_slice()` method of splitting the string apart can perform poorly for large input strings. I think this is mostly just the large number of calls plus building and returning an array being not entirely trivial.

See PHI87. Ref T12974. Currently, we do a lot more work here than we need to: we call `phutil_utf8_strtolower()` on each token, but can do it once at the beginning on the whole block.

36df39761e Create revisions into "Draft", publish them when builds finish
Summary:
Ref T2543. This doesn't stand alone since mail still goes out normally, but gets this piece working: new revisions start as "Draft", then after updates if there are no builds they go into "Needs Review".

This should work in general because builds update revisions when they complete, to publish a "Harbormaster finished build yada yada" transaction. So either we'll un-draft immediately, or un-draft after the last build finishes.

I'll hold this until the mail and some other stuff (like UI hints) are in slightly better shape since I think it's probably too rough on its own.

Summary: See PHI79. When you edit another user's SSH keys (normally, for a bot account) we currently redirect you to an older URI.

Test Plan:
  - Viewed a bot's profile page.
  - Clicked "Edit Settings" on the Manage page.
  - Went to "SSH Keys".
  - Uploaded an SSH key.
  - Before: redirected to a 404 after finishing the workflow.
  - After: redirected to the same page after the workflow.

3fbad684c1 More completely explain why we're refusing to send reset mail to an unverified address
Summary:
See PHI78. The user was getting this message and (reasonably) interpreted it to mean "reset mail can never be sent to unverified addresses".

Reword it to be more clear, albeit an entire paragraph long. I don't really have a good solution in these cases where we'd need a whole page to explain what's happening (this, plus "we can't tell you which address you should use because an attacker could get information if we did" and "this rule defuses the risk that an opportunistic attacker may try to compromise your account after you add an email you don't own by mistake"). We could write it up separately and link to it, but I feel like that stuff tends to get out of date.

Just land somewhere in the middle.

23867c1487 Add a "Draft" state for revisions, and action bucket support
Summary:
Ref T2543. There's no way to put revisions into this state yet, but start adding support for when there is.

Adds the status constant, plus support for bucketing them.

Test Plan:
  - Manually put a revision in "Draft" state by updating the database directly.
  - Verified my drafts showed up in a "Drafts" section on the bucket view.
  - Verified others' drafts did not appear on the action bucket view.
  - Viewed revisions, queried for "Draft" revisions, etc (stuff we get for free).

156adccef0 Fix an issue where "bin/differential migrate-hunk" could decompress data
Summary:
Fixes T12986. I caught this bug in the changes from D18584: when we moved a large hunk to file storage, we would decompress it but keep the "deflated" flag. This could cause confusion when loading it later. I missed this in testing since I wasn't exhaustive enough in checking hunks and didn't run into a compressed one.

Instead of compressing on `save()`, compress during the normal workflow.

We currently never advise users to run this workflow so I didn't bother trying to clean up possible existing migrations.

Test Plan:
  - Ran `bin/differential migrate-hunk` on compressed hunks, moving them to and from file storage. Saw them work correctly and remain compressed.
  - Created new small (uncompressed) and large (compressed) hunks, verified they work properly and get compressed (if applicable).
  - Used `bin/cache purge --caches changeset` to clear changeset caches and make sure the actual table was being hit.

3ad727ba78 Guarantee the key_position key is created properly
Summary:
Ref T12987. I was focused on the RefCursor table and overlooked that we need some care on this key.

It's currently possible to run `bin/storage upgrade --no-adjust`, then start Phabricator, and end up with duplicate records in this table. If you try to run `bin/storage adjust` later, it will try to add the unique key but fail. This is unusual for normal installs (they usually do not use `--no-adjust`) but we do it in the cluster and I did this exact thing on `secure`.

Normally, to avoid this, when a new table with a unique key is introduced, we also add a migration to explicitly add that key.

This is mostly harmless in this case. Fix this mistake (force the table to contain only unique rows; add the key) and try using `LOCK TABLES` to make this atomic. If this doesn't cause problems we can use this in similar situations in the future.

The "alter table may unlock things" warning comes from here:

https://dev.mysql.com/doc/refman/5.7/en/lock-tables.html

It seems like it's fine to issue `UNLOCK TABLES` even if you don't have any locks, so I think this script should always do the right thing now, regardless of ALTER TABLE unlocking or not unlocking tables.

Test Plan: Ran `bin/storage upgrade -f`, saw table end up in the right state. I'll also check this on `secure`, where the starting state is a little messier.

51b810b0eb Fix "Author's projects" Herald rules for revisions and diffs
Summary:
See PHI71. These didn't get properly updated when we wrote Subprojects and Milestones, and should use materialized members, not raw members. Swap the query so projects you are an indirect member of (e.g., milestones you are a member of the parent for, and parent projects you are a member of a subproject of) are included in the result list.

Also fix a bad typeahead datasource.

Test Plan:
  - Ran a dry run with the test console, saw project PHIDs for milestones and parent projects in the raw field value.
  - Tried to set "Author's projects" to a user, no longer could.

8982e3e52d Update major RefCursor callsites to work properly with RefPosition
Summary:
Ref T11823. This is the meaty part of the change, and updates `RefEngine` to use separate RefCursor (for names) and RefPosition (for actual commit positions) tables.

I'll hold this whole series until after the release cut so it has some time to bake on `secure` to look for issues. It's also not a huge problem if there are bugs here since these tables are just caches anyway, although they do feed into some other things, and obviously it's never good to have bugs.

Test Plan:
  - This logic can be invoked directly with `bin/repository refs <repository> --trace --verbose`.
  - Ran that on unchanged repositories, new branches, removed branches, and modified branches. Saw appropriate output and cursor positions.
  - Ran on a mercurial repository to test the close/open logic, saw it correct open/closed state of incorrect positions.
  - Browed around Diffusion in various repositories.

782b18e7e2 Migrate RefCursor data to RefPosition table
Summary:
Ref T11823. This populates the new RefPosition table based on the existing RefCursor table, and deletes now-duplicate rows in the RefCursor table so the next change can add a unique key.

This change is not standalone, and there need to be separate code updates. I have a rough version of that written, but this migration needs to happen first to test it.

I'll hold this whole series of changes until after the release cut and until the code is updated.

Test Plan: Ran migration, spot-checked database tables. Saw redundant rows remove and correct-looking rows populated into the new RefPosition table.

9d5a2b3b4f Add a RefPosition table to hold branch/tag positions once the RefCursor table is split
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.)

Test Plan: Ran `bin/storage upgrade`, saw the table get created without warnings.

bd923d1ce0 Provide an explicit "-R" flag to "hg serve"
Summary:
See <https://discourse.phabricator-community.org/t/unable-to-use-current-mercurial-on-debian-stretch/391>.

The Mercurial commit is helpful in particular: <https://www.mercurial-scm.org/repo/hg/rev/77eaf9539499>

We weren't vulnerable to the security issue (users can not control any part of the command) but pass the working directory explicitly to get past the new safety check.

I left `setCWD()` in place (a few lines below) just because it can't hurt, and in some other contexts it sometimes matter (for example, if commit hooks execute, they might inherit the parent CWD here or in other VCSes).

Test Plan:
  - Cloned from a Mercurial repo locally over HTTP.
  - Verified that SSH cloning already uses `-R` (it does, see `DiffusionMercurialServeSSHWorkflow`).
  - Did not actually upgrade to Mercurial 4.0/4.1.3 to completely verify this, but a user in the Discourse thread asserted that a substantially similar fix worked correctly.
