Ref T12450. The way that config repair and setup issues interact is kind of complicated, and if `cluster.search` is invalid we may end up using `cluster.search` before we repair it.
I poked at things for a bit but wasn't confident I could get it to consistently repair before we use it without doing a big messy change.
The only thing that really matters is whether "type" is valid or not, so just put a slightly softer/more-tailored check in for that.
Test Plan:
- With `"type": "elastic"`, loaded setup issues.
- Before patch: hard fatal.
- After patch: softer fatal with more useful messaging.

However, you can also change config by editing `local.json`, `some_env.conf.php`, a `SiteConfig` class, etc. In these cases, you may miss config warnings.
Explicitly re-run search config checks from `bin/search`, similar to the additional database checks we run from `bin/storage`, to try to produce a better error message if the user has made a configuration error.

- setRoles() has no callers.
- getRoles() has no callers (these two methods are leftovers from an earlier iteration of the change).
- The `hasRole()` logic doesn't work since nothing calls `setRole()`.
- `hasRole()` has only `isreadable/iswritable` as callers.
- The `isReadable()/isWritable()` logic doesn't work since `hasRole()` doesn't work.
Instead, just check if there are any readable/writable hosts. `Host` already inherits its config from `Service` so this gets the same answer without any fuss.
Also add some read/write constants to make grepping this stuff a little easier.

Summary:
[ ] Write an "Upgrading: ..." guidance task with narrow instructions for installs that are upgrading.
[ ] Do we need to add an indexing activity (T11932) for installs with ElasticSearch?
[ ] We should more clearly detail exactly which versions of ElasticSearch are supported (for example, is ElasticSearch <2 no longer supported)? From T9893 it seems like we may //only// have supported ElasticSearch <2 before, so are the two regions of support totally nonoverlapping and all ElasticSearch users will need to upgrade?
[ ] Documentation should provide stronger guidance toward MySQL and away from Elastic for the vast majority of installs, because we've historically seen users choosing Elastic when they aren't actually trying to solve any specific problem.
[ ] When users search for fulltext results in Maniphest and hit too many documents, the current behavior is approximately silent failure (see T12443). D17384 has also lowered the ceiling for ElasticSearch, although previous changes lowered it for MySQL search. We should not fail silently, and ideally should build toward T12003.
[ ] D17384 added a new "keywords" field, but MySQL does not search it (I think?). The behavior should be as consistent across MySQL and Elastic as we can make it. Likely cleaner is giving "Project" objects a body, with "slugs" and "description" separated by newlines?
[ ] `PhabricatorSearchEngineTestCase` is now pointless and only detects local misconfigurations.
[ ] It would be nice to build a practical test suite instead, where we put specific documents into the index and then search for them. The upstream test could run against MySQL, and some `bin/search test` could run against a configured engine like ElasticSearch. This would make it easier to make sure that behavior was as uniform as possible across engine implementations.
[ ] Does every assigned task now match "user" in ElasticSearch?
[x] `PhabricatorElasticFulltextStorageEngine` has a `json_encode()` which should be `phutil_json_encode()`.
[ ] `PhabricatorSearchService` throws an untranslated exception.
[ ] When a search cluster is down, we probably don't degrade with much grace (unhandled exception)?
[ ] I haven't run bin/search init, but bin/search index doesn't warn me that I may want to. This might be worth adding. The UI does warn me.
[ ] bin/search init warns me that the index is "incorrect". It might be more clear to distinguish between "missing" and "incorrect", since it's more comforting to users to see "everything is as we expect, doing normal first-time setup now" than "something is wrong, fixing it".
[ ] CLI message "Initializing search service "ElasticSearch"" does not end with a period, which is inconsistent with other UI messages.
[ ] It might be nice to let bin/search commands like init and index select a specific service (or even service + host) to act on, as bin/storage --ref ... now does. You can generally get the result you want by fiddling with config.
[ ] When a service isn't writable, bin/search init reports "Search cluster has no hosts for role "write".". This is accurate but does not provide guidance: it might be more useful to the user to explain "This service is not writable, so we're skipping index check for it.".
[x] Even with write off for MySQL, bin/search index --type task --trace still updates MySQL, I think? I may be misreading the trace output. But this behavior doesn't make sense if it is the actual behavior, and it seems like reindexAbstractDocument() uses "all services", not "writable services", and the MySQL engine doesn't make sure it's writable before indexing.
[x] Searching or user fails to find task Grant users tokens when a mention is created, suggesting that stemming is not working.
[x] Searching for users finds that task, but fails to find a task containing "per user per month" in a comment, also suggesting that stemming is not working.
[x] Searching for maniphest fails to find task maniphest.query elephant, suggesting that tokenization in ElasticSearch is not as good as the MySQL tokenization for these words (see D17330).
[x] The "index incorrect" warning UI uses inconsistent title case.
[x] The "index incorrect" warning UI could format the command to be run more cleanly (with addCommand(), I think).

Summary:
The goal is to make fulltext search back-ends more extensible, configurable and robust.
When this is finished it will be possible to have multiple search storage back-ends and
potentially multiple instances of each.
Individual instances can be configured with roles such as 'read', 'write' which control
which hosts will receive writes to the index and which hosts will respond to queries.
These two roles make it possible to have any combination of:
* read-only
* write-only
* read-write
* disabled
This 'roles' mechanism is extensible to add new roles should that be needed in the future.
In addition to supporting multiple elasticsearch and mysql search instances, this refactors
the connection health monitoring infrastructure from PhabricatorDatabaseHealthRecord and
utilizes the same system for monitoring the health of elasticsearch nodes. This will
allow Wikimedia's phabricator to be redundant across data centers (mysql already is,
elasticsearch should be as well).
The real-world use-case I have in mind here is writing to two indexes (two elasticsearch clusters
in different data centers) but reading from only one. Then toggling the 'read' property when
we want to migrate to the other data center (and when we migrate from elasticsearch 2.x to 5.x)
Hopefully this is useful in the upstream as well.
Remaining TODO:
* test cases
* documentation
Test Plan:
(WARNING) This will most likely require the elasticsearch index to be deleted and re-created due to schema changes.
Tested with elasticsearch versions 2.4 and 5.2 using the following config:
```lang=json
"cluster.search": [
{
"type": "elasticsearch",
"hosts": [
{
"host": "localhost",
"roles": { "read": true, "write": true }
}

"protocol": "http",
"path": "/phabricator",
"version": 5
},
{

"roles": { "write": true }

Also deployed the same changes to Wikimedia's production Phabricator instance without any issues whatsoever.

The `min()` vs `max()` fix in D17560 meant that the Trigger daemon only

There are some situations where communication can be more clear if users can accept as only themselves, or for only some packages, etc. T12271 discusses some of these use cases in more depth.
Instead of making "Accept" a blanket action, default it to doing what it does now but let the user uncheck reviewers.
In cases where project/package reviewers aren't in use, this doesn't change anything.
For now, "reject" still acts the old way (reject everything). We could make that use checkboxes too, but I'm not sure there's as much of a use case for it, and I generally want users who are blocking stuff to have more direct accountability in a product sense.

The major issues here are:
1. Edges use constants internally, which aren't great for an API.
2. A lot of edges are internal and probably not useful to query.
3. Edges don't have a real "id", so paginating them properly is challenging.
I've solved these things like this:
- Edges must opt-in to being available via Conduit by providing a human-readable key (like "mention" instead of "52"). This solvs (1) and (2).

Summary:
Ref T12298. The trigger daemon already has routine long-term sleep, and few external events can impact when it should ideally wake up. The relevant events are:
- Someone creates a new Nuance source (ideally, we should wake up right away and start polling it).
- Someone creates a Calendar event about 16 minutes in the future (ideally, we should send them a reminder in about a minute).
- Someone changes GC config to be extremely aggressive (ideally, we should immediately respect the change).
None of these cases are very important. We don't hibernate for more than 3 minutes, so the worst case is that your Nuance source takes 3 minutes to start importing or your Calendar notification comes two minutes too late (13 minutes before the event instead of 15).
This change makes GC sightly more CPU-expensive on average: currently, we do a GC sweep every 4 hours. After this change, we'll end up doing one every 3 minutes, because we lose the fact that we did a sweep recently when the daemon restarts.
We could fix this by keeping track of when the last GC sweep was in the database, instead of in the Daemon process, but the cost of a sweep is normally very small so I don't plan to do this anytime soon.

- Ran `bin/phd debug trigger`, saw daemon go through 3-minute hibernate + restart cycles.

We use `spl_object_hash()` to identify objects when passing hints about policy changes to policy rules. This is hacky, and I think it's the source of the unit test issue.
Specifically, `spl_object_hash()` is approximately just returning the memory address of the object, and two objects can occasionally use the same memory address (one gets garbage collected; another uses the same memory).
If I replace `spl_object_hash()` with a static value like "zebra", the test failure reproduces.
Instead, sneak an object ID onto a runtime property. This is at least as hacky but shouldn't suffer from the same intermittent failure.

However, if we don't warn users about this they'll just get a broken index unless they go read the changelog (or file an issue, then we tell them to go read the changelog).
This adds a very simple table for notes to administrators so we can write a "you need to go rebuild the index" note, then adds one.
Administrators clear the note by completing the activity and running `bin/config done reindex`. This isn't automatic because there are various strategies you can use to approach the issue, which I'll discuss in greater detail in the linked documentation.

Ref T11044. Sometimes we have a sequence of patches like this:
- `01.newtable.sql`: Adds a new table to Files.
- `02.movedata.php`: Moves some data that used to live in Tokens to the new table.
This is fairly rare, but not unheard of. More commonly, we can have this sequence:
- `03.newtable.sql`: Add a new column to Phame.
- `04.setvalue.php`: Copy data into that new column.
In both cases, when applying database-by-database, we can get into trouble.
- In the first case, if Files is on a different master, we'll try to move data into a new table before creating the table.
- In the second case, if Phame is on a different master, the PHP patch will connect to it before we add the new column.
In either case, we try to interact with tables or columns which don't exist yet.
Instead, apply each patch in order, to all databases which need it. So we'll apply `01.newtable.sql` EVERYWHERE first, then move on.
In the case of PHP patches, we also now only apply them once, since they never make schema changes. It should normally be OK to apply them more than once safely, but this is a little faster and a little safer if we ever make a mistake.

- Ran `bin/storage upgrade` on single-host and clustered setups.

In modern Phabricator, you can subclass `SiteConfig` to provide dynamic configuration, and we do so in the Phacility cluster. This lets you change any config, and change in response to requests (e.g., for instancing) and is generally more powerful than this mechanism was.
This configuration provider theoretically let you roll your own replication or partitioning, but in practice I believe no one ever did, and no one ever could have anyway without more support in the upstream (for migrations, read-after-write, etc).

Ref T11044. One popular tool in a modern operations environment is Puppet. The primary purpose of this tool is to randomly revert hosts to older or different configurations.
Introducing an element of chaotic unpredictability into operations trains staff to be on high alert at all times, rather than lulled into complacency by predictability or consistency.
When Puppet reverts a Phabricator host's configuration to an older version, we might start writing data to a lot of crazy places where it shouldn't go. This will create a big sticky mess that is virtually impossible to undo, mostly because we'll get two files with ID 123 or two tasks with ID 456 or whatever else and good luck with that.
Instead, after changing the partition layout, require `bin/storage partition` to be run. This writes a copy of the config everywhere.
Then, when we start serving web requests, make sure every database has the exact same config. This will foil Puppet by refusing to run requests on hosts it has reverted.
Test Plan:
- Changed partition configuration.
- Ran Phabricator.
- FOILED!
- Ran `bin/storage partition` to sync config.

Summary:
Ref T10759. Currently, these checks run only against configured masters. Instead, check every host.
These checks also sort of cheat through restart during a recovery, when some hosts will be unreachable: they test for "disaster" by seeing if no masters are reachable, and just skip all the checks in that case.
This is bad for at least two reasons:
- After recent changes, it is possible that //some// masters are dead but it's still OK to start. For example, "slowvote" may have no master, but everything else is reachable. We can safely run without slowvote.
- It's possible to start during a disaster and miss important setup checks completely, since we skip them, get a clean bill of health, and never re-test them.
Instead:
- Test each host individually.
- Fundamental problems (lack of InnoDB, bad schema) are fatal on any host.
- If we can't connect, raise it as a //warning// to make sure we check it later. If you start during a disaster, we still want to make sure that schemata are up to date if you later recover a host.
In particular, I'm going to add these checks soon:
- Fatal if a "master" is replicating.
- Fatal if a "replica" is not replicating.
- Fatal if a database partition config differs from web partition config.
- When we let a database off with a warning because it's down, and later upgrade it to a fatal because we discover it is broken after it comes up again, fatal everything. Currently, we keep running if we "discover" the presence of new fatals after surviving setup checks for the first time.

- Configured with multiple masters, intentionally broke one (simulating a disaster where one master is lost), saw Phabricator still startup.

- 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 T10867 for original use case. This workflow provides a plausible way for administrators to stop the daemons when performing upgrades or maintenance, then bring those daemons back up without resulting in the failure of builds that were running at the time.
On our organization's phab install, builds are running 24/7. The majority of these builds last for at least several minutes, and contain build steps which fail if interrupted and then resumed, as happens when turning daemons on and off.
Instead of allowing these build steps to resume execution as normal, this workflow will instruct active builds to restart their entire build process instead of just resuming whichever step they were on.
Test Plan:
contrived a build plan which would fail if resumed partway through:
- lease a working copy
- command `touch restart_{build.id}`
- command `test -e restart_{build.id} && rm restart_{build.id} && sleep 60`
followed old procedure:
- run a few of these builds manually
- `./bin/phd stop`
- `./bin/phd start`
- saw the builds fail
followed new procedure:
- run a few of these builds manually
- `./bin/phd stop`
- `./bin/harbormaster restart --active`
- `./bin/phd start`
- saw the builds pass

Summary: Ref T11132. This gets rid of the red bar for admins and instead shows a new menu item next to notifications/chat if there are unresolved configuration issues. Menu goes away if there are no issues. May move this later into the bell icon, but think think might be the right place to start especially for NUX and updates. Maybe limit the number of items?
Test Plan:
Tested with some, lots, and no config issues.

Summary: Previously, the chatbot docs instructed users to get certificates for the conduit API and put the cert in a `conduit.cert` config key. In order to get the chatbot to work, I needed to instead get an API key and put it in the `conduit.token` config entry.
Test Plan: Doc fix. Tried the new documented way and it worked.

Summary: Fixes T11508. The config entry `remarkup.ignored-object-names` already contains a blacklist of object names that should be ignored in the web UI. This change makes that blacklist also apply to the chatbot. This makes it possible to have a chatbot ignore things like V1, V2, Q1 and any other phrases the user may not want to generate links to objects.
Test Plan: Create objects (tasks, slowvotes, etc.) then mention the object names in chat (with the bot running). The bot should respond with helpful links to the given objects. Then add the object names to the blacklist through the config web UI. This apparently triggers the bot to restart itself. Then mention the object names in chat again. The bot should no longer respond with links because those object names have been added to the blacklist regex.

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.

Fixes T11490. Currently, this query can not use a key and the table size may be quite large.
Adjust the query so it can use a key for both selection and ordering, and add that key.
Test Plan: Ran `EXPLAIN` on the old query in production, then added the key and ran `EXPLAIN` on the new query. Saw key in use, and "rows" examined drop from 29,273 to 15.

Summary:
Ref T6996. Depends on D16407. This does the same stuff as D16407, but for `bin/storage renamespace`. In particular:
- Support writing directly to a file (so we can get good errors on failure).
- Support in-process compression.
Also add support for reading out of a `storage dump` subprocess, so we don't have to do a dump-to-disk + renamespace + compress dance and can just stream out of MySQL directly to a compressed file on disk.
This is used in the second stage of instance exports (see T7148).
It would be nice to share more code with `bin/storage dump`, and possibly to just make this a flag for it, although we still do need to do the file-based version when importing (vs exporting). I figured that was better left for another time.
Test Plan:
Ran `bin/storage renamespace --live --output x --from A --to B --compress --overwrite` and similar commands.
Verified that a compressed, renamespaced dump came out of the other end.

Summary:
Ref T6996. If you do this kind of thing in the shell, you don't get a good error by default if the `dump` command fails:
```
$ bin/storage dump | gzip > output.sql.gz
```
This can be worked around with some elaborate bash tricks, but they're really clunky and uninintuitive.
We also need to do this in several places (while writing backups; while performing exports), and I don't want to copy clunky bash tricks all over the codebase.
Instead, provide `--output` and `--compress` flags which just do this processing inside `bin/storage dump`. It will fail appropriately if any of the underlying operations fail. This also makes the write a little safer (refuses to overwrite) and the code more reusable.
Test Plan:
- Did three dumps, with no flags, `--output`, and `--output --compress`.
- Verified all three took similar amounts of time and were identical except for "Date Exported" timestamps in comments (except that the compressed one was compressed).
- Used `gunzip` to examine the compressed one, verified it was really compressed.
- Faked a write error, saw properly command behavior (clean up file + exit with error).

Summary:
The cluster synchronization code runs either actively (before returning a response to `git clone`, for example) or passively (routinely, as the daemons update reposiories).
The active sync runs as the web user (if running `git clone http://...`) or the VCS user (if running `git clone ssh://...`). But the passive sync runs as the daemon user.
All of these sync processes need to run actual commands as the daemon user (`git fetch ...`).
For the active ones, we must `sudo`.
For the passive ones, we're already the right user. We run the same code, and end up trying to sudo to ourselves, which `sudo` isn't happy about by default.
Depending on how `sudo` is configured and which users things are running as this might work anyway, but it's silly and if it doesn't work it requires you to go make non-obvious, weird config changes that are unintuitive and somewhat nonsensical. This is probably worse on the balance than adding a bit of complexity to the code.
Instead, test which user we're running as. If it's already the right user, don't sudo.
Test Plan:
- Ran `bin/repository update --trace` as daemon user, saw no more `sudo`.
- Ran a `git clone` to make sure that didn't break.

Summary:
Ref T11458. Depends on D16388. Currently, we're very aggressive about closing connections in the taskmaster daemons.
This can end up taking up a lot of resources. In particular, because the outgoing port for outbound connections normally can not be reused for 60 seconds after a connection closes, we may exhaust outbound ports on the host if there's a big queue full of stuff that's being processed very quickly.
At a minimum, we //always// are holding open a `worker` connection, which we always need again right away. So even in the best case we end up opening/closing this about once per second and each daemon takes up about ~60 outbound ports when it should take up ~1.
So, make two adjustments:
- First, only close connections which we haven't issued a query on in the last 60 seconds. This should prevent us from closing connections that we'll need again immediately in most cases. In the worst case, we shouldn't be eating up any extra ports under default TCP behavior.
- Second, explicitly close connections. We were relying on implicit/GC behavior (maybe as a holdover from very long ago, before we got connection wrappers in place?), which probably did about the same thing but isn't as predictable and can't be profiled or instrumented.
Test Plan:
This is somewhat difficult to test completely convincingly in isolation since the problem behavior depends on production scales and the workload, and to some degree on configuration.
I tested that this stuff baiscally works by adding logging to connect/close and running the daemons, verifying that they churned connections a lot before this change (e.g., ~1/s even at no load) and churn rarely afterward (e.g., almost never at no load).
I ran some workload through them to make sure I didn't completely break anything.
The best real test is just seeing how production responds. Current inbound/outbound connections on `secure001` are 1,200:
```
secure001 $ netstat -t | grep :mysql | wc -l
1164
```
Current outbound from `repo001` are 18,600:
```
repo001 $ netstat -t | grep :mysql | wc -l
18663
```

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.
