bbb321395a Support Aphlict clustering
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?)

  - Adds a "--host" flag. If you specify this, we read your cluster config. This lets you dump from a replica.
  - Adds a "--for-replica" flag to `storage dump`. This makes `mysqldump` include a `CHANGE MASTER ...` statement in the output, which is useful when setting up a replica for the first time.

ca6da4c2be When proxying the SVN protocol, don't mutate URIs in protocol frames if we're an intracluster proxy
Summary:
Ref T10809. Currently, both the proxy and target may mutate URIs (rewriting "svn+ssh://x/diffusion/Y/" to a path on disk).

I believe this previously worked by fate/chance/luck since both URI variants contain the repository information, but the algorithms were tightened up recently with callsign removal.

Stop rewriting them if we're the intracluster proxy -- they only need to be rewritten on the target host.

Test Plan:
  - Checked out a proxied SVN repository, with and without a callsign.
  - Checked out an unproxied SVN repository, with and without a callsign.

d4bf2a147b Make paths and Aphlict instance names less ambiguous
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.

e32ce529d7 Begin generalizing Aphlict server to prepare for clustering/sensible config file
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.

4244cad990 Move toward multi-master replicated repositories
Summary:
Ref T4292. This mostly implements the locking/versioning logic for multi-master repositories. It is only active on Git SSH pathways, and doesn't actually do anything useful yet: it just does bookkeeping so far.

When we read (e.g., `git fetch`) the logic goes like this:

- Get the read lock (unique to device + repository).
  - Read all the versions of the repository on every other device.
  - If any node has a newer version:
    - Fetch the newer version.
    - Increment our version to be the same as the version we fetched.
- Release the read lock.
- Actually do the fetch.

This makes sure that any time you do a read, you always read the most recently acknowledged write. You may have to wait for an internal fetch to happen (this isn't actually implemented yet) but the operation will always work like you expect it to.

When we write (e.g., `git push`) the logic goes like this:

- Get the write lock (unique to the repository).
  - Do all the read steps so we're up to date.
  - Mark a write pending.
    - Do the actual write.
  - Bump our version and mark our write finished.
- Release the write lock.

This allows you to write to any replica. Again, you might have to wait for a fetch first, but everything will work like you expect.

There's one notable failure mode here: if the network connection between the repository node and the database fails during the write, the write lock might be released even though a write is ongoing.

The "isWriting" column protects against that, by staying locked if we lose our connection to the database. This will currently "freeze" the repository (prevent any new writes) until an administrator can sort things out, since it'd dangerous to continue doing writes (we may lose data).

(Since we won't actually acknowledge the write, I think, we could probably smooth this out a bit and make it self-healing //most// of the time: basically, have the broken node rewind itself by updating from another good node. But that's a little more complex.)

Test Plan:
  - Pushed changes to a cluster-mode repository.
  - Viewed web interface, saw "writing" flag and version changes.
  - Pulled changes.
  - Faked various failures, got sensible states.

ac35246d0d Never sever non-cluster database; write more read-only documentation
Summary:
Ref T4571. Write more of the missing documentation sections and clarify a few things.

Since the "replicating master" check needs a special permission, imposes a performance penalty, is probably very difficult to misconfigure, and likely not a big deal anyway, just drop the idea of trying to automatically detect + prevent it. We still show if it's an issue on the status page, provided we have permission to check.

When you don't have any cluster databases configured, never stop trying to connect to the default master database. We might want to do this eventually as load reduction, but just don't muddy the waters too much for now while things stabilize.

ebff07d019 Automatically sever databases after prolonged unreachability
Summary:
Ref T4571. When a database goes down briefly, we fall back to replicas.

However, this fallback is slow (not good for users) and keeps sending a lot of traffic to the master (might be bad if the root cause is load-related).

Keep track of recent connections and fully degrade into "severed" mode if we see a sequence of failures over a reasonable period of time. In this mode, we send much less traffic to the master (faster for users; less load for the database).

We do send a little bit of traffic still, and if the master recovers we'll recover back into normal mode seeing several connections in a row succeed.

This is similar to what most load balancers do when pulling web servers in and out of pools.

For now, the specific numbers are:

  - We do at most one health check every 3 seconds.
  - If 5 checks in a row fail or succeed, we sever or un-sever the database (so it takes about 15 seconds to switch modes).
  - If the database is currently marked unhealthy, we reduce timeouts and retries when connecting to it.

Test Plan:
  - Configured a bad `master`.
  - Browsed around for a bit, initially saw "unrechable master" errors.
  - After about 15 seconds, saw "major interruption" errors instead.
  - Fixed the config for `master`.
  - Browsed around for a while longer.
  - After about 15 seconds, things recovered.
  - Used "Cluster Databases" console to keep an eye on health checks: it now shows how many recent health checks were good:

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.

e0a8cac703 When no master database is configured, automatically degrade to read-only mode
Summary: Ref T4571. If `cluster.databases` is configured but only has replicas, implicitly drop to read-only mode and send writes to a replica.

Test Plan:
  - Disabled the `master`, saw Phabricator automatically degrade into read-only mode against replicas.
  - (Also tested: explicit read-only mode, non-cluster mode, properly configured cluster mode).

071741c61d When Phabricator is in read-only mode, explain why
Summary:
Ref T4571. Allows users to click the "read-only mode" notification to get more information about why an install is in read-only mode.

Installs can be in this mode for several reasons (explicit administrative action, no masters defined, no masters reachable), and it's useful to be able to tell the difference.

c178f29cdb Use new first-class MySQL timeout support in Phabricator
Summary: Fixes T6710. After D15669, we support a proper timeout parameter, so we don't need this hack anymore.

Test Plan: See D15669: forced a MySQL connector, set a low timeout, set a bad database, saw fast failures.

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.

3f51b78539 Lay cluster.databases configuration groundwork for database clustering
Summary:
Ref T4571. This adds a new option which allows you to upgrade your one-host configuration to a multi-host configuration by configuring it.

Doing this currently does nothing. I wrote a lot of words about what it is //supposed// to do in the future, though.

Test Plan:
  - Tried to configure the option in all the possible bad ways, got errors.
  - Read documentation.

49d93dcf98 Add a cluster.read-only option
Summary:
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.

60e91d3934 Fix an issue with passing HTTP headers through in proxied cluster requests
Summary:
I think this fixes the Mercurial + HTTP cluster issue. PHP adds `HTTP_` but we were not stripping it, so we would convert an `X-Whatever-Zebra` header into an `Http-X-Whatever-Zebra` header.

I don't think this behavior has changed? So maybe it just never worked? Git is more popular than Mercurial and SSH is easier to configure than HTTP, so it's plausible. I'll keep a careful eye on this when it deploys.

Test Plan:
  - Set up local service-based Mercurial repository.
  - Tried to clone, got similar error to cluster.
  - Applied patch, clean clone.
