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).

- The CSRF error happens when bots hit anything which does write checks.
- The "wrong cookie domain" errors happen when bots try to use the `security.alternate-file-domain` to browse stuff like `/auth/start/`.
- The "no phcid" errors happen when bots try to go through the login flow.
All of these are clearly communicated to human users, commonly encountered by bots, and not useful to log.
I collapsed the `CSRFException` type into a standard malformed request exception, since nothing catches it and I can't really come up with a reason why anything would ever care.

Summary:
Ref T11473. If you write a method like `get_stuff(ids)` and then call it with an empty list of IDs, you can end up passing an empty constraint to Conduit.
If you run a `*.search` method with such a constraint, like this one:
```
{
"ids": []
}
```
...we have three possible beahviors:
# Treat it like the user passed no constraint (basically, ignore the constraint).
# Respect the constraint (return no results).
# Error.
Currently, we do (1). However, this is pretty confusing and I think clearly the worst option, since it means `get_stuff(array())` in client code will often tend to return a ton of results.
We could do (2) instead, but this is also sort of confusing (it may not be obvious why nothing matched, even though it's an application bug) and I think most reasonable client code should be doing an `if ($ids)` test: this test makes clients a little more complicated, but they can save a network call, and I think they often need to do this test anyway (for example, to show the user a different message).
This implements (3), and just considers these to be errors: this is the least tricky behavior, it's consistent with what we do in PHP, makes fairly good sense, and the only cost for this is that client code may need to be slightly more complex, but this slightly more complex code is usually better code.
Test Plan: Ran Conduit `*.search` queries with `"ids":[]` and `"phids":[]`, got sensible errors instead of runaway result sets.

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

Summary:
If contributors use "history.immutable" by default (for example, in user/global config) and then try to contribute to Phabricator, they might land in a way that creates merge commits, which we'd prefer to avoid.
To make this a bit harder to do unintentionally, set "history.immutable" to "false" explicitly in `.arcconfig`. This will override any user or system setting and keep `land` in squash mode in this project.
This might also be a problem in general, and maybe in the long term we need something like one of these warnings:
> (when arc landing) You haven't landed changes to this project before, are you sure you want to create a merge commit / are you sure you want to squash?
...or:
> (when doing anything) This project doesn't have a history.immutable setting; you should probably set one so user settings don't win out.
...or just not let this be set at the user/system level, although that's annoying in some cases. Also maybe this:
> (when arc landing) You're about to create a merge commit, but the last Differential change in history squashed instead. Merge anyway?
However, we haven't seen this as a widespread issue outside of this project yet (and even in this project I think it has only happened 2-3 times), so just put up a guard rail in our own configuration for now.
Test Plan:
- Ran `arc set-config history.immutable true` to set the flag in my user settings.
- Ran `arc get-config` to verify that the setting overrode system/user settings:
```
epriestley@orbital ~/dev/phabricator $ arc get-config history.immutable --verbose
history.immutable
If true, arc will never change repository history (e.g., through amending
or rebasing). Defaults to true in Mercurial and false in Git. This
