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
```

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.

A "Publisher" represents an individual or entity who is publishing a package, like "Phacility". It's explicitly //not// necessarily the original author -- just the primary entity vouching for the safety of the code.
A publisher just has a name and a unique key for now. For example, Phacility might have "Phacility" and "phacility", respectively.
Unique keys are immutable, e.g., the package "phacility/arcanist" will always be exactly the same package by exactly the same publisher.

Summary:
Ref T6915. This allows multiple notification servers to talk to each other:
- Every server has a list of every other server, including itself.
- Every server generates a unique fingerprint at startup, like "XjeHuPKPBKHUmXkB".
- Every time a server gets a message, it marks it with its personal fingerprint, then sends it to every other server.
- Servers do not retransmit messages that they've already seen (already marked with their fingerprint).
- Servers learn other servers' fingerprints after they send them a message, and stop sending them messages they've already seen.
This is pretty crude, and the first message to a cluster will transmit N^2 times, but N is going to be like 3 or 4 in even the most extreme cases for a very long time.
The fingerprinting stops cycles, and stops servers from sending themselves copies of messages.
We don't need to do anything more sophisticated than this because it's fine if some notifications get lost when a server dies. Clients will reconnect after a short period of time and life will continue.
Test Plan:
- Wrote two server configs.
- Started two servers.
- Told Phabricator about all four services.
- Loaded Chrome and Safari.
- Saw them connect to different servers.
- Sent messages in one, got notifications in the other (magic!).
- Saw the fingerprinting stuff work on the console, no infinite retransmission of messages, etc.
(This pretty much just worked when I ran it the first time so I probably missed something?)

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.

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.

Summary:
Ref T7149. When users give us dumpfiles for import, they will almost inevitably use the `phabricator` namespace. They need to be renamed to use an instance namespace.
We can do this either by:
- importing the data first, then renaming; or
- renaming first, then importing.
This implements the second one, basically `storage renamespace --in dump.sql --from phabricator --to instancename > instance.sql`.
Renaming first is a little hackier since we have to `preg_match()` a SQL dump file, but I think it's better overall:
- With only one database, it lets you dump/import without downtime.
- If you have development stuff in a development environment in the `phabricator` namespace, you don't have to move it aside to do an import.
- No possibility that two people doing an import at the same time on the same box will collide with each other.
- You can do the rename once and then repeat the import process with the renamed dump more easily.
- No tricky stuff with modern Phabricator running against an old dump and the database names not matching up.
None of this is super important, but it just makes large dumps a bit easier to work with, and the dumpfile format is regular enough that this seems unlikely to ever really not work.
Test Plan: Renamespaced a dump, did a `diff -u`, saw all the relevant parts changed (and only those parts changed).

- 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.

Also adds more warnings about old MySQL. Note that we already issue a warning when you run "storage adjust" (which I've made stronger) and already "strongly recommend" MySQL 5.5 or newer in the install documentation.
Test Plan:
- Ran `storage adjust --disable-utf8mb4` to go to old definitions, then ran `storage adjust` to get back to the new ones. Everything seemed OK in both cases.
- Verified that utf8mb4 data can be migrated out of these colums with `--unsafe` (which will truncate).
- Verified that manual explains this.
- Faked my way into the setup warning.

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.

Ref T3165. Builds a dedicated index for Conpherence to avoid scale/policy filtering concerns.
- This is pretty one-off but I think it's generally OK.
- There's no UI for it.
- `ConpherenceFulltextQuery` is very low-level. You would need to do another query on the PHIDs it returns to actually show anything to the user.
- The `previousTransactionPHID` is so you can load chat context efficiently. Specifically, if you want to show results like this:
> previous line of context
> **line of chat that matches the query**
> next line of context
...you can read the previous lines out of `previousTransactionPHID` directly, and the next lines by issuing one query with `WHERE previousTransactionPHID IN (...)`.
I'm not 100% sure this is useful, but it seemed like a reasonable thing to provide, since there's no way to query this efficiently otherwise and I figure a lot of chat might make way more sense with a couple of lines of context.
Test Plan:
- Indexed a thread manually (whole thing indexed).
- Indexed a thread by updating it (just the new comment indexed).
- Wrote a hacky test script and got reasonable-looking query results.

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

Found no adjustments for schemata.
Target Error

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

- 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.
