This is a fix for PHP 8.1 deprecation of strlen(NULL), for these Phorge components:

The strlen() was used in Phabricator to check if a generic value was a non-empty string.
For this reason, Phorge adopts phutil_nonempty_string() that checks that.
Note: this may highlight other absurd input values that might be worth correcting
instead of just ignoring. If your phutil_nonempty_string() throws an exception, just
report it to Phorge to evaluate and fix together that specific corner case.

Summary:
Fixes T13392. If you have 17 load balancers in sequence, Phabricator will receive requests with at least 17 "X-Forwarded-For" components in the header.
We want to select the 17th-from-last element, since prior elements are not trustworthy.
This currently isn't very easy/obvious, and you have to add a kind of sketchy piece of custom code to `preamble.php` to do any "X-Forwarded-For" parsing. Make handling this correctly easier.
Test Plan:
- Ran unit tests.
- Configured my local `preamble.php` to call `preamble_trust_x_forwarded_for_header(4)`, then made `/debug/` dump the header and the final value of `REMOTE_ADDR`.

Summary:
Ref T12822. The next change hits these warnings but I think neither is a net positive.
The "function called before it is defined" error alerts on this kind of thing:
```
function a() {
b();
}
function b() {
}
a();
```
Here, `b()` is called before it is defined. This code, as written, is completely safe. Although it's possible that this kind of construct may be unsafe, I think the number of programs where there's unsafe behavior here AND the whole thing doesn't immediately break when you run it at all is very very small.
Complying with this warning is sometimes impossible -- at least without cheating/restructuring/abuse -- for example, if you have two functions which are mutually recursive.
Although compliance is usually possible, it forces you to define all your small utility functions at the top of a behavior. This isn't always the most logical or comprehensible order.
I think we also have some older code which did `var a = function() { ... }` to escape this, which I think is just silly/confusing.
Bascially, this is almost always a false positive and I think it makes the code worse more often than it makes it better.
---
The "unused function parameter" error warns about this:
```
function onevent(e) {
do_something();
```
We aren't using `e`, so this warning is correct. However, when the function is a callback (as here), I think it's generally good hygiene to include the callback parameters in the signature (`onresponse(response)`, `onevent(event)`, etc), even if you aren't using any/all of them. This is a useful hint to future editors that the function is a callback.
Although this //can// catch mistakes, I think this is also a situation where the number of cases where it catches a mistake and even the most cursory execution of the code doesn't catch the mistake is vanishingly small.
Test Plan: Egregiously violated both rules in the next diff. Before change: complaints. After change: no complaints.

This is generally a good change, but code written against PHP 5.x before `Throwable` was introduced may not catch these errors, even when the code is intended to be a top-level exception handler.
(The double-catch pattern here and elsewhere is because `Throwable` does not exist in older PHP, so `catch (Throwable $ex)` catches nothing. The `Exception $ex` clause catches everything in old PHP, the `Throwable $ex` clause catches everything in newer PHP.)
Generalize some `Exception` into `Throwable`.

Summary:
Depends on D18987. See PHI343. Fixes T13060. See also T7339.
When the main process starts up with `LANG=POSIX` (this is the default on Ubuntu) and we later try to run a subprocess with a UTF8 character in the argument list (like `git cat-file blob 🐑.txt`), the argument is not passed to the subprocess correctly.
We already set `LANG=en_US.UTF-8` in the //subprocess// environment, but this only controls behavior for the subprocess itself. It appears that the argument list encoding before the actual subprocess starts depends on the parent process's locale setting, which makes some degree of sense.
Setting `putenv('LANG=en_US.UTF-8')` has no effect on this, but my guess is that the parent process's locale setting is read at startup (rather than read anew from `LANG` every time) and not changed by further modifications of `LANG`.
Using `setlocale(...)` does appear to fix this.
Ideally, installs would probably set some UTF-8-compatible LANG setting as the default. However, this makes setup harder and I couldn't figure out how to do it on our production Ubuntu AMI after spending a reasonable amount of time at it (see T13060).
Since it's very rare that this setting matters, try to just do the right thing. This may fail if "en_US.UTF-8" isn't available, but I think warnings/remedies to this are in the scope of T7339, since we want this locale to exist for other legitimate reasons anyway.
Test Plan:
- Applied this fix in production, processed the failing worker task from PHI343 after kicking Apache hard enough.
- Ran locally with `setlocale(LC_ALL, 'duck.quack')` to make sure a bad/invalid/unavailable setting didn't break anything, didn't hit any issues.

Summary:
Depends on D18702. Ref T13008. This replaces the old hard-coded single rate limit with multiple flexible limits, and defines two types of limits:
- Rate: reject requests if a client has completed too many requests recently.
- Connection: reject requests if a client has too many more connections than disconnections recently.
The connection limit adds +1 to the score for each connection, then adds -1 for each disconnection. So the overall number is how many open connections they have, at least approximately.
Supporting multiple limits will let us do limiting by Hostname and by remote address (e.g., a specific IP can't exceed a low limit, and all requests to a hostname can't exceed a higher limit).
Configuring the new limits looks something like this:
```
PhabricatorStartup::addRateLimit(new PhabricatorClientRateLimit())
->setLimitKey('rate')
->setClientKey($_SERVER['REMOTE_ADDR'])
->setLimit(5);
PhabricatorStartup::addRateLimit(new PhabricatorClientConnectionLimit())
->setLimitKey('conn')
->setClientKey($_SERVER['REMOTE_ADDR'])
->setLimit(2);

- Made a lot of requests, got cut off by the rate limit.
- Used `curl --limit-rate -F 'data=@the_letter_m.txt' ...` to upload files really slowly. Got cut off by the connection limit. With `enable_post_data_reading` off, this correctly killed the connections //before// the uploads finished.

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.

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.

- Wrote two server configs.
- Started two servers.
- Told Phabricator about all four services.

- 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: Fixes T10806. Although browsers don't seem to care about this, it's more correct to support it, and the new test console uses normal `cURL` and does care.
Test Plan:
- Hit the error case for providing a chain but no key/cert.
- Used `openssl s_client -connect localhost:22280` to connect to local Aphlict servers.
- With SSL but no chain, saw `openssl` fail to verify the remote.
- With SSL and a chain, saw `openssl` verify the identify of the remote.

Summary:
Fixes T10783 (what little of it remains). Ref T10697.
Aphlict currently uses request paths for two different things:
- multi-tenant instancing in the Phacility cluster (each instance gets its own namespace within an Aphlict server);
- some users configure nginx and apache to do proxying or SSL termination based on the path.
Currently, these can collide.
Put a "~" before the instance name to make it unambiguous. At some point we can possibly just use a GET parameter, but I think there was some reason I didn't do that originally and this sequence of changes is disruptive enough already.
Test Plan: Saw local Aphlict unambiguously recognize "local.phacility.com" as instance "local", with a "~"-style URI.

Summary:
Fixes T10697. This finishes bringing the rest of the config up to cluster power levels.
Phabricator is now given an arbitrarily long list of notification servers.
Each Aphlict server is given an arbitrarily long list of ports to run services on.
Users are free to make them meet in the middle by proxying whatever they want to whatever else they want.
This should also accommodate clustering fairly easily in the future.
Also rewrote the status UI and changed a million other things. 🐗

Summary: Ref T10697. Mostly straightforward. Also allow the server to have multiple logs and log options in the future (e.g., different verbosities or separate admin/client logs or whatever). No specific plans for this, but the default log is pretty noisy today.
Test Plan: Set up a couple of logs, started server, saw it log to them.

Summary: Ref T10697. This isn't everything but starts generalizing options and moving us toward a cluster-ready state of affairs.
Test Plan: Started server in various configurations, hit most (all?) of the error cases with bad configs, sent test notifications.

Summary:
Ref T10697. Currently, `aphlict` takes a ton of command line flags to configure exactly one admin server and exactly one client server.
I want to replace this with a config file. Additionally, I plan to support:
- arbitrary numbers of listening client ports;
- arbitrary numbers of listening admin ports;
- SSL on any port.
For now, just transform the arguments to look like they're a config file. In the future, I'll load from a config file instead.
This greater generality will allow you to do stuff like run separate HTTP and HTTPS admin ports if you really want. I don't think there's a ton of use for this, but it tends to make the code cleaner anyway and there may be some weird cross-datacneter cases for it. Certainly, we undershot with the initial design and lots of users want to terminate SSL in nginx and run only HTTP on this server.
(Some sort-of-plausible use cases are running separate HTTP and HTTPS client servers, if your Phabricator install supports both, or running multiple HTTPS servers with different certificates if you have a bizarre VPN.)
Test Plan: Started Aphlict, connected to it, sent myself test notifications, viewed status page, reviewed logfile.

Summary:
Ref T10604. This uses the new standalone stream reader introduced in D15483 to read request data, instead of putting the logic in PhabricatorStartup.
It also doesn't read request data until it specifically needs to. This supports, e.g., streaming Git LFS PUT requests, and streaming more types of requests in the future.
Test Plan: See D15483. Made various different types of requests and wasn't immediately able to break anything.

Summary:
Ref T10264. Under PHP 5.6, you are no longer allowed to use `compress.zlib://php://input` as an argument to either `fopen()` or `file_get_contents()`.
Instead, open `php://input` as a file handle, then add `zlib.inflate` as a stream wrapper. This requires some level of magic to work properly.
Test Plan:
First, I constructed a synthetic gzipped payload by typing some words into a file and using `gzcompress()` to compress it.
Then I used a `curl` command like this to make requests with it:
```
$ curl -X POST -H "Content-Length: 66" -H "Content-Type: text/plain" -H "Content-Encoding: gzip" --data-binary @payload.deflate -v http://127.0.0.1/
```
I modified Phabricator to just dump the raw request body and exit, and reproduced the issue under PHP 5.6 (no body, error in log) by brining up a micro instance in EC2 and installing php56 on it.
After this patch, it dumped the body properly instead, and PHP 5.5 also continued worked properly.

Summary:
Mostly, this has just been sitting in my sandbox for a long time. I may also touch some charting stuff with subprojects/milestones, but don't have particular plans to do that.
D3 seems a bit more flexible, and it's easier to push more of the style logic into CSS so you can fix my design atrocities. gRaphael also hasn't been updated in ~3+ years.

Summary:
Fixes T10228. When we receive a gzipped request (rare, but `git` may send them), decode it before providing it to the application.
This fixes the issue with proxying certain requests described in T10228.
Test Plan:
- Applied this fix in production.
- Cloned a problem repository cleanly.
