8c89fc38fc Allow persistent connections to be configured per database host
Summary: Ref T11044. Fixes T11672. In T11672, persistent connections seem to work fine, but they can require `max_connections` and other settings to be raised. Since most users don't need them, make them an advanced option.

Test Plan: Configured persistent connections, loaded some pages, observed persistent connections get used.

e6bfa1bd23 Remove "mysql.configuration-provider" configuration option
Summary:
Ref T11044. This was old Facebook cruft for reading configuration from SMC (and maybe doing some other questionable things). See D183.

(See also D175 for discussion of this from 2011.)

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).

Test Plan:
  - Grepped for removed option.
  - Browsed around with clustering off.

bac27fb403 Remove "mysql.implementation" configuration
Summary:
Ref T11044. Fixes T10931. This option has essentially never been useful for anything, and we've picked the best implementation for a long time (MySQLi if available, MySQL if not).

I am not aware of any reason to ever set this manually. If someone comes up with some bizarre but legitimate use case that I haven't thought of, we can modularize it.

55e21565b5 Support application partitioning across multiple masters
Summary:
Ref T11044. I'm going to hold this until after the release cut, but I think it's good to go.

This allows installs to configure multiple masters in `cluster.databases` and partition applications across them (for example, put Maniphest on a dedicated database).

When we make a Maniphest connection we go look up which master we should be hitting first, then connect to it.

This has at least approximately been planned for many years, so the actual change is largely just making sure that your config makes sense.

Test Plan:
  - Configured `db001.epriestley.com` and `db002.epriestley.com` as master/master.
  - Partitioned applications between them.
  - Interacted with various applications, saw writes go to the correct host.
  - Viewed "Database Servers" and saw partitioning information.
  - Ran schema upgrades.

Summary:
Ref T11044. This moves toward partitioned application databases:

  - You can define multiple masters.
  - Convert all the easily-convertible code to become multi-master aware.

This doesn't convert most of `bin/storage` or "Config > Database (Stuff)" yet, as both are quite involved. They still work for now, but only operate on the first master instead of all masters.

Test Plan: Configured multiple masters, browsed around, ran `bin/storage` commands, ran `bin/storage --host ...`.

38b10f05a2 For now, disable persistent connections and the "max_connections" setup warning
Summary:
Ref T11672. At low loads, this causes us to use more connections, which is pushing some installs over the default limits.

Rather than trying to walk users through changing `max_connections`, `open_files_limit`, `fs.file-max`, `ulimit`, etc., just put things back for now. After T11044 we should have headroom to use persistent connections within the default limits on all reasonable systems..

f8c2225268 Use persistent database connections from web contexts
Summary:
Ref T11672. Depends on D16577. When establishing a connection from a webserver context, try to use persistent connections.

The hope is that this will fix outbound port exhaustion issues experienced on repository hosts handling large queue volumes.

Test Plan:
Added this to a page:

```lang=php
    $tables = array(
      new PhabricatorUser(),
      new ManiphestTask(),
      new DifferentialRevision(),
      new PhabricatorRepository(),
      new PhabricatorPaste(),
    );

    $ids = array();
    foreach ($tables as $table) {
      $conn = $table->establishConnection('r');

      $cid = queryfx_one(
        $conn,
        'SELECT CONNECTION_ID() cid');

      $ids[get_class($table)] = $cid['cid'];
    }

    var_dump($ids);
```

Reloaded the page a bunch of times and saw no reissued connections (the pool seems to keep a particular connection bound to a particular database), but did see connection reuse across requests.

That is, across reloads the same connection IDs appeared, but the same connection ID never appeared twice in the same request. This is what we want.

Also googled for issues with persistent connections, but everything I found was unconcerning and obscure (local variables and other very complex state that we don't use), and a bunch of the docs are reassuring (transactions, etc., get reset properly).

5e3efca08a In taskmaster daemons, only close connections which were not used recently
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
```

e8083ad63a Increase the storage size for commit summaries
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.

9827cc1622 Provide a missing timeout on the non-cluster connection pathway
Summary:
Ref T11232. The cluster connection pathway specifies a timeout when connecting, but this connection pathway does not. (I'm not sure if we just never did or if it got lost at some point.)

Soon, T11044 will obsolete this and unify the database connection pathways, but that's a more complicated change.

I'm not sure if this will fix T11232, but it can't hurt.

146fb646f9 Automatically degrade to read-only mode when unable to connect to the master
Summary:
Ref T4571. If we fail to connect to the master, automatically try to degrade into a temporary read-only mode ("UNREACHABLE") for the remainder of the request, if possible.

If the request was something like "load the homepage", that'll work fine. If it was something like "submit a comment", there's nothing we can do and we just have to fail.

Detecting this condition imposes a performance penalty: every request checks the connection and gives the database a long time to respond, since we don't want to drop writes unless we have to. So the degraded mode works, but it's really slow, and may perpetuate the problem if the root issue is load-related.

This lays the groundwork for improving this case by degrading futher into a "SEVERED" mode which will persist across requests. In the future, if several requests in a short period of time fail, we'll sever the database host and refuse to try to connect to it for a little while, connecting directly to replicas instead (basically, we're "health checking" the master, like a load balancer would health check a web application server). This will give us a better (much faster) degraded mode in a major service disruption, and reduce load on the master if the root cause is load-related, giving it a better chance of recovering on its own.

Test Plan:
  - Disabled master in config by changing the host/username, got degraded automatically to UNREACAHBLE mode immediately.
  - Faked full SEVERED mode, requests hit replicas and put me in the mode properly.
  - Made stuff work, hit some good pages.
  - Hit some non-cluster pages.

6a4a9bb2d2 When cluster.databases is configured, read the master connection from it
Summary:
Ref T4571. Ref T10759. Ref T10758. This isn't complete, but gets most of the job done:

  - When `cluster.databases` is set up, most things ignore `mysql.host` now.
  - You can `bin/storage upgrade` and stuff works.
  - You can browse around in the web UI and stuff works.

There's still a lot of weird tricky stuff to navigate, and this has real no advantages over configuring a single server yet (no automatic failover, etc).

Test Plan:
  - Configured `cluster.databases` to point at my `t1.micro` hosts in EC2 (master + replica).
  - Ran `bin/storage upgrade`, got a new install setup on them properly.
  - Survived setup warnings, browsed around.
  - Switched back to local config, ran `bin/storage upgrade`, browsed around, went through setup checks.
  - Intentionally broke config (bad hosts, no masters) and things seemed to react reasonably well.

49d93dcf98 Add a cluster.read-only option

Ref T4571. There will be a very long path beyond this, but add a basic read-only mode. You can explicitly enable this to put Phabricator in a sort of "maintenance" mode today if you're swapping databases or something.

In the long term, we'll automatically degrade into this mode if the master database is down.

Test Plan:
  - Enabled read-only mode.
  - Browsed around.
  - Didn't immediately see anything that was totally 100% broken.

Most stuff is 80-90% broken right now. For example:

  - Stuff like submitting comments doesn't work, and gives you a confusing, unhelpful error.
  - None of the UI really knows that it's read-only. EditEngine stuff should all hide itself and say "you can't add new comments while an install is in read-only mode", for example, but currently does not.

3ef270b292 Allow transaction publishers to pass binary data to workers
Summary:
Ref T8672. Ref T9187. Root issue in at least one case is:

  - User makes a commit including a file with some non-UTF8 text (say, a Japanese file full of Shift-JIS).
  - We pass the file to the TransactionEditor so it can inline or attach the patch if the server is configured for these things.
    - When inlining patches, we convert them to UTF8 before inlining. We must do this since the rest of the mail is UTF8.
    - When attaching patches, we send them in the original encoding (as file attachments). This is correct, and means we need to give the worker the raw patch in whatever encoding it was originally in: we can't just convert it to utf8 earlier, or we'd attach the wrong patch in some cases.
  - TransactionEditor does its thing (e.g., creates the commit), then gets ready to send mail about whatever it did.
  - The publishing work now happens in the daemon queue, so we prepare to queue a PublishWorker and pass it the patch (with some other data).
  - When we queue workers, we serialize the state data with JSON.

So far, so good. But this is where things go wrong:

  - JSON can't encode binary data, and can't encode Shift-JIS. The encoding silently fails and we ignore it.

Then we get to the worker, and things go wrong-er:

  - Since the data is bad, we fatal. This isn't a permanent failure, so we continue retrying the task indefinitely.

This applies several fixes:

  # When queueing tasks, fail loudly when JSON encoding fails.
  # In the worker, fail permanently when data can't be decoded.
  # Allow Editors to specify that some of their data is binary and needs special handling.

This is fairly messy, but some simpler alternatives don't seem like good ways forward:

  - We can't convert to UTF8 earlier, because we need the original raw patch when adding it as an attachment.
  - We could encode //only// this field, but I suspect some other fields will also need attention, so that adding a mechanism will be worthwhile. In particular, I suspect filenames //may// be causing a similar problem in some cases.
  - We could convert task data to always use a serialize()-based binary safe encoding, but this is a larger change and I think it's correct that things are UTF8 by default, even if it makes a bit of a mess. I'd rather have an explicit mess like this than a lot of binary data floating around.

The change to make `LiskDAO` will almost certainly catch some other problems too, so I'm going to hold this until after `stable` is cut. These problems were existing problems (i.e., the code was previously breaking or destroying data) so it's definitely correct to catch them, but this will make the problems much more obvious/urgent than they previously were.

Test Plan:
  - Created a commit with a bunch of Shift-JIS stuff in a file.
  - Tried to import it.

Prior to patch:

  - Broken PublishWorker with distant, irrelevant error message.

With patch partially applied (only new error checking):

  - Explicit, local error message about bad key in serialized data.

With patch fully applied:

  - Import went fine and mail generated.

827c0ce081 Allow LiskDAO to be forced to use a specific connection
Summary:
Ref T7522. This seems like the least-bad approach to a messy issue:

  - When backfilling accounts from an imported instance, I need to write ExternalAccount rows to the instance to link instance accounts with upstream accounts.
  - We do this in the daemons in some other cases, which lets us run all the code in the context of the instance. However, I really want to do this in-process here because it's way way simpler and we need to do writes to //both// the instance and the upstream, and they're interleaved, and they depend on one another.
  - I can hard-code the query with `qsprintf()` but that feels like 100x worse than this.

This allows me to do this:

```
id(new PhabricatorExternalAccount())
  ->setForcedConnnection($instance_conn)
  ->...
  ->save();
```

...and get a write to the instance database, which is at least not completely a minefield.

Test Plan: Backfilled instance accounts and got interleaved instance and upstream writes as expected.

29fd3f136b Allow columns to be marked as nonmutable (so save() will not change them)
Summary:
Ref T6840. This feels a little dirty; open to alternate suggestions.

We currently have a race condition where multiple daemons may load a commit and then save it at the same time, when processing "reverts X" text. Prior to this feature, two daemons would never load a commit at the same time.

The "reverts X" load/save has no effect (doesn't change any object properties), but it will set the state back to the loaded state on save(). This overwrites any flag updates made to the commit in the meantime, and can produce the race in T6840.

In other cases (triggers, harbormaster, repositories) we deal with this kind of problem with "append-only-updates + single-consumer", or a bunch of locking. There isn't really a good place to add a single consumer for commits, since a lot of daemons need to access them. We could move the flags column to a separate table, but this feels pretty complicated. And locking is messy, also mostly because we have so many consumers.

Just exempting this column (which has unusual behavior) from `save()` feels OK-ish? I don't know if we'll have other use cases for this, and I like it even less if we never do, but this patch is pretty small and feels fairly understandable (that said, I also don't like that it can make some properties just silently not update if you aren't on the lookout).

So, this is //a// fix, and feels simplest/least-bad for the moment to me, I thiiink.

Test Plan: Added and executed unit tests.

Summary:
Ref T6881. This is part 1 of my 35-step plan to support subscriptions that bill monthly.

Expanding the capabilities of counters will let me use them to create a logical clock on time-based event updates, build a daemon on top of that, and eventually get time-based triggers.

000760b645 Do a better job of handling spec errors during schema adjustment
Summary:
Ref T1191. Currently if a developer forgot to specify a column type, `storage adjust` aborts explosively mid-stream. Instead:

  - Make this a formal error with an unambiugous name/description instead of something you sort of infer by seeing "<unknown>".
  - Make this error prevent generation of adjustment warnings, so we don't try to `ALTER TABLE t CHANGE COLUMN c <unknown>`, which is nonsense.
  - When schemata errors exist, surface them prominiently in `storage adjust`.

Overall:

  - Once `storage upgrade` runs `storage adjust` automatically (soon), this will make it relatively difficult to miss these errors.
  - Letting these errors slip through no longer escalates into a more severe issue.

Test Plan:
Commented out the recent `mailKey` spec and ran `storage adjust`:

```
$ ./bin/storage adjust --force
Verifying database schemata...
Found no adjustments for schemata.

Target                                            Error
phabricator2_phriction.phriction_document.mailKey Column Has No Specification

 SCHEMATA ERRORS

The schemata have serious errors (detailed above) which the adjustment
workflow can not fix.

If you are not developing Phabricator itself, report this issue to the
upstream.

If you are developing Phabricator, these errors usually indicate that your
schema specifications do not agree with the schemata your code actually
builds.

f86f9dc512 Make Currency a more formal type
Summary:
Ref T2787. Phortune currently stores a bunch of stuff as `...inUSDCents`. This ends up being pretty cumbersome and I worry it will create a huge headache down the road (and possibly not that far off if we do Coinbase/Bitcoin soon). Even now, it's more of a pain than I figured it would be.

Instead:

  - Provide an application-level serialization mechanism.
  - Provide currency serialization.
  - Store currency in an abstract way (currently, as "1.23 USD") that can handle currencies in the future.
  - Change all `...inUSDCents` to `..asCurrency`.
  - This generally simplifies all the application code.
  - Also remove some columns which don't make sense or don't make sense anymore. Notably, `Product` is going to get more abstract and mostly be provided by applications.

Test Plan:
  - Created a new product.
  - Purchased a product.
  - Backed an initiative.
  - Ran unit tests.

300172e799 Support AUTO_INCREMENT in bin/storage adjust
Summary:
Ref T1191. When changing the column type of an AUTO_INCREMENT column, we currently may lose the autoincrement attribute.

Instead, support it. This is a bit messy because AUTO_INCREMENT columns interact with PRIMARY KEY columns (tables may only have one AUTO_INCREMENT column, and it must be a primary key). We need to migrate in more phases to avoid this issue.

Introduce new `auto` and `auto64` types to represent autoincrement IDs.

Test Plan:
  - Saw autoincrement show up correctly in web UI.
  - Fixed an autoincrement issue on the XHProf storage table with `bin/storage adjust` safely.

Summary:
Ref T1191. Three parts:

  - The old way of getting key information only got primary / unique / foreign keys, not all keys. Use `SHOW INDEXES` to get all keys instead.
  - Track key uniqueness and raise warnings about it.
  - Add a new "all issues" view to show an expanded, flat view of all issues. This is just an easier way to get a list so you don't have to dig around in the hierarchical view.

aa481dba57 Begin generating meaningful expected schemata
Summary:
Ref T1191. This lays some groundwork for generating the expected schemata, so we can compare them to the actual schemata and produce a meaningful diff.

  - In general, each application will subclass `PhabricatorConfigSchemaSpec` and provide a definition of the tables it expects.
  - This class has helper methods to mostly-automatically build table definitions for Lisk and (in the future) edges.
  - When building expected schema, we specify a "data type", like "epoch". This is the type of data the application stores in the column, from the application's point of view. The SchemaSpec converts this into the best avilable storage type: for example, "text" will translate to `utf8mb4` if it's availalbe, or `binary` if not. This gives us a layer of indirection to insulate us from craziness.

Test Plan: See screenshots.

See some discussion here:

24a6eeb8d8 (commitcomment-7334892)

The `protected $properties;` storage parameter added to `ProjectColumn` is shadowed by `getProperties()` in the base class.
