See discussion in D4204. Facebook currently has a 314MB remarkup cache with a 55MB index, which is slow to access. Under the theory that this is an index size/quality problem (the current index is on a potentially-384-byte field, with many keys sharing prefixes), provide a more general index with fancy new features:
- It implements PhutilKeyValueCache, so it can be a component in cache stacks and supports TTL.
- It has a 12-byte hash-based key.
- It automatically compresses large blocks of data (most of what we store is highly-compressible HTML).
Test Plan:
- Basics:
- Loaded /paste/, saw caches generate and save.
- Reloaded /paste/, saw the page hit cache.
- GC:
- Ran GC daemon, saw nothing.
- Set maximum lifetime to 1 second, ran GC daemon, saw it collect the entire cache.
- Deflate:
- Selected row formats from the database, saw a mixture of 'raw' and 'deflate' storage.
- Used profiler to verify that 'deflate' is fast (12 calls @ 220us on my paste list).

- **Image**: Each Moleskine has one or more images, like the unexpanded / expanded / mobile / empty states of feed.
- **Transaction**: Comment or edit, like Maniphest. I generally want to move most apps to a transaction model so we can log edits.

People hit three issues with D3914:
- As per T2059, we applied a schema change from a `.php` patch, which currently does not work if you use a different user to make schema changes than for normal use.
- Since the change in question is idempotent, just move it to a `.sql` patch. We'll follow up in T2059 and fix it properly.
- Rogue daemons at several installs used old code (expecting autoincrement) to insert into the new table (no autoincrement), thereby creating tasks with ID 0.
- Rename the table so they'll fail.
- This also makes the code a little more consistent.
- Some installs now have tasks with ID 0.
- Use checks against null rather than against 0 so we can process these tasks.
The major issues this fixes are the schema upgrade failure in T2059, and the infinite loops in T2072 and elsewhere.
This isn't really a fully statisfactory fix. I'll discuss some next steps in T2072.

- Move `resourceType` from worker task metadata directly to `DrydockLease`. Other things (like the web UI) can be more informative with this information available.
- Pass leases to `allocateResource()`. We always allocate in response to a lease activation request, and the lease often has vital information. This also allows us to associate logs with leases correctly.

Summary:
This was the major goal of D3859/D3855, and to a lesser degree D3854/D3852.
As Drydock is allocating a resource, it may need to allocate other resources first. For example, if it's allocating a working copy, it may need to allocate a host first.
Currently, we have the process basically queue up the allocation (insert a task into the queue) and sleep() until it finishes. This is problematic for a bunch of reasons, but the major one is that if allocation takes more resources (host, port, machine, DNS) than you have daemons, they could all end up sleeping and waiting for some other daemon to do their work. This is really stupid. Even if you only take up some of them, you're spending slots sleeping when you could be doing useful work.
To partially get around this and make the CLI experience less dumb, there's this goofy `synchronous` flag that gets passed around everywhere and pushes the workflow through a pile of special cases. Basically the `synchronous` flag causes us to do everything in-process. But this is dumb too because we'd rather do things in parallel if we can, and we have to have a lot of special case code to make it work at all.
Get rid of all of this. Instead of sleep()ing, try to work on the tasks that need to be worked on. If another daemon grabbed them already that's fine, but in the worst case we just gracefully degrade and do everything in process. So we get the best of both worlds: if we have parallelizable tasks and free daemons, things will execute in parallel. If we have nonparallelizable tasks or no free daemons, things will execute in process.
Test Plan: Ran `drydock_control.php --trace` and saw it perform cascading allocations without sleeping or special casing.

Summary:
This leaves the UI in a pretty rough state, but implements blog policy controls and queries, and 1:1 relationships between posts and blogs. Needs a bunch more cleanup but seemed like an okayish breaking point in terms of cohesiveness.
Posts have these rules:
- Drafts are visible only to the author.
- Published posts are visible to anyone who can see the blog they appear on.
- Posts are only editable by the author.
...so we don't need any special policy UI or state to accommodate these rules.
Posts may have no blog if they're grandfathered in or you write a post to a blog and then lose the ability to see the blog. This is the messiest edge case -- specifically:
- You write a post to blog A.
- You publish the post.
- I edit the "Visible To:" for blog A and set it to exclude you.
What we do in this case is let you see the post in "My Posts", but you can no longer see the blog and you'll see the post as not being part of a blog. We can maybe give you some UI to let you move it later or something.
Test Plan: Hit all (I think?) of the interfaces without issues. Definitely some UI problems still right now.

Fixes a TODO, and silences a warning introduced by D3601.
There are several cases where we load data like:
SELECT *, ... AS extraData FROM ...
...and then pass it to `loadAllFromArray()`. Currently, this causes us to set an `extraData` property on the object.
This idiom seems fairly useful and non-dangerous, so I made `loadFromArray()` just drop extra keys.
Since we hit this loop a potentially huge number of times (10,000+ for full Maniphest pages) I did some microoptimization. Lisk is hot enough that it's one of the few places where it's worthwhile (see D1291).

I would much rather see a linter warning me against this than this runtime check but writing it is very difficult:
- We need to explore all parents of the class we are checking.
- It is even possible that children will declare that property but it's OK to treat this as error anyway.
- We can extend also builtin or external classes.
- It's somewhat doable for `$this` but even more complex for any `$obj` because we don't know the class of it.
This should catch significant part of these errors and I'm fine with that.

Summary:
To make it easier to monitor daemons, let's store their current state
(running, died, exited, or unknown) to the db. The purpose of this is to
provide more information on the daemon console about the status of daemons,
especially when they are running on multiple machines. This is mostly backend
work, with only a few frontend changes. (It is also dependent on a change
to libphutil.)
These changes will make dead or stuck daemons more obvious, and will allow
more work on the frontend to hide daemons (and logs) that have exited cleanly,
i.e. ones we don't care about any more.
Test Plan:
- run db migration, check in db that all daemons were marked as exited
- start up a daemon, check in db that it is marked as running
- open web interface, check that daemon is listed as running
- after daemon has been running for a little bit, check in db that dateModified
is being updated (indicating daemon is properly sending heartbeat)
- kill -9 daemon (but don't run bin/phd yet), and check that db still shows it
as running
- edit daemon db entry to show it as being on a different host, and backdate
dateModified field by 3 minutes, and check the web ui to show that the status
is unknown.
- change db entry to have proper host, check in web ui that daemon status is
displayed as dead. Check db to see that the status was saved.
- run bin/phd stop, and see that the formerly dead daemon is now exited.

Summary:
Lisk currently behaves in two different ways if you call it like `load("cow")` (throws) versus `load(99999999)` (returns null), where neither ID exists.
This was intended to catch programming errors as distinct from missing data, but in practice the former is very rare and you have to handle the latter in most cases anyway. The case where you pass "0" is particularly confusing. See D2971 for an example.
On the balance, I think this ends up being far more confusing than helpful. Instead, just return NULL if we're sure there's no such object.
Test Plan: Reasoned about program behavior.

Summary:
The immediate issue this addresses is T1366, adding a rendering cache to Phriction. For wiki pages with code blocks especially, rerendering them each time is expensive.
The broader issue is that out markup caches aren't very good right now. They have three major problems:
**Problem 1: the data is stored in the wrong place.** We currently store remarkup caches on objects. This means we're always loading it and passing it around even when we don't need it, can't genericize cache management code (e.g., have one simple script to drop/GC caches), need to update authoritative rows to clear caches, and can't genericize rendering code since each object is different.
To solve this, I created a dedicated cache database that I plan to move all markup caches to use.
**Problem 2: time-variant rules break when cached.** Some rules like `**bold**` are time-invariant and always produce the same output, but some rules like `{Tnnn}` and `@username` are variant and may render differently (because a task was closed or a user is on vacation). Currently, we cache the raw output, so these time-variant rules get locked at whatever values they had when they were first rendered. This is the main reason Phriction doesn't have a cache right now -- I wanted `{Tnnn}` rules to reflect open/closed tasks.
To solve this, I split markup into a "preprocessing" phase (which does all the parsing and evaluates all time-invariant rules) and a "postprocessing" phase (which evaluates time-variant rules only). The preprocessing phase is most of the expense (and, notably, includes syntax highlighting) so this is nearly as good as caching the final output. I did most of the work here in D737 / D738, but we never moved to use it in Phabricator -- we currently just do the two operations serially in all cases.
This diff splits them apart and caches the output of preprocessing only, so we benefit from caching but also get accurate time-variant rendering.
**Problem 3: cache access isn't batched/pipelined optimally.** When we're rendering a list of markup blocks, we should be able to batch datafetching better than we do. D738 helped with this (fetching is batched within a single hunk of markup) and this improves batching on cache access. We could still do better here, but this is at least a step forward.
Also fixes a bug with generating a link in the Phriction history interface ($uri gets clobbered).
I'm using PHP serialization instead of JSON serialization because Remarkup does some stuff with non-ascii characters that might not survive JSON.
Test Plan:
- Created a Phriction document and verified that previews don't go to cache (no rows appear in the cache table).
- Verified that published documents come out of cache.
- Verified that caches generate/regenerate correctly, time-variant rules render properly and old documents hit the right caches.

Summary:
In unit tests which use fixtures, we open transactions on every connection we establish. However, since we don't track connections that are established with "$force_new" (currently, only GlobalLock connections) we never close these transactions normally.
Instead of not tracking these connections, track them using unique keys so we'll never get a cache hit on them.
Test Plan: Built unit tests on top of this, had them stop dying from unclosed transactions.

Basically, MySQL usually raises a good error if we exceed "max_allowed_packet":
EXCEPTION: (AphrontQueryException) #1153: Got a packet bigger than 'max_allowed_packet' bytes
But sometimes it gives us a #2006 instead. This is documented, at least:
>"With some clients, you may also get a Lost connection to MySQL server during query error if the communication packet is too large."
http://dev.mysql.com/doc/refman//5.5/en/packet-too-large.html
Try to improve the error message to point at this as a possible explanation.
Test Plan: Faked an error, had it throw, read exception message. See also chatlog.
