Summary:
We currently cache all connections in LiskDAO so we can roll back transactions when fixtured unit tests complete.
Since we establish a new connection wrapper each time we establish a global lock, this cache currently grows without bound.
Instead, pool global lock connections so we never have more than the largest number of locks we've held open at once (in PullLocalDaemon, always 1).
Another way to solve this is probably to add an "onclose" callback to `AphrontDatabaseConnection` so that it can notify any caches that it been closed. However, we currently allow a connection to be later reopened (which seeems reasonable) so we'd need a callback for that too. This is much simpler, and this use case is unusual, so I'd like to wait for more use cases before pursing a more complicated fix.
Test Plan:
Ran this in a loop:
while (true) {
for ($ii = 0; $ii < 100; $ii++) {
$lock = PhabricatorGlobalLock::newLock('derp');
$lock->lock();
$lock->unlock();

Summary:
I'm trying to make progress on the policy/visibility stuff since it's a blocker for Wikimedia.
First, I want to improve Projects so they can serve as policy groups (e.g., an object can have a visibility policy like "Visible to: members of project 'security'"). However, doing this without breaking anything or snowballing into a bigger change is a bit awkward because Projects are name-ordered and we have a Conduit API which does offset paging. Rather than breaking or rewriting this stuff, I want to just continue offset paging them for now.
So I'm going to make PhabricatorPolicyQuery extend PhabricatorOffsetPagedQuery, but can't currently since the `executeWithPager` methods would clash. These methods do different things anyway and are probably better with different names.
This also generally improves the names of these classes, since cursors are not necessarily IDs (in the feed case, they're "chronlogicalKeys", for example). I did leave some of the interals as "ID" since calling them "Cursor"s (e.g., `setAfterCursor()`) seemed a little wrong -- it should maybe be `setAfterCursorPosition()`. These APIs have very limited use and can easily be made more consistent later.

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:
Some facts are aggregations of other facts. For example, we may compute how many times each macro is used in each object as a "raw fact":
Dnnn uses macro "psyduck" 6 times.
But we want to present this data in aggregate form, e.g. "order macros by popularity". We can do this at runtime and it probably won't be too awful a query, but we can also aggregate it cheaply:
Macro "psyduck" is used 3920 times across all objects.
...and then do a query like "select macros ordered by usage".
"Aggregate" facts support facts like this. The aggregate facts I've implemented are:
- Count of all objects.
- Count of objects of type X.
- Last time facts were updated.
These clearly fit the "aggregate" facts template well. I'm not 100% sure macros do. We can use this table to answer a question like "What are the most popular macros, ordered by use?" We can also use it to answer a question like "What are the most popular macros in the last 6 months?", if we build a specific fact for that. But we can't use it to answer a question like "What are the most popular macros between times X and Y?". Maybe that's important; maybe not.
This seems like a good fit for at least some types of facts.
I'll de-magic the keys a bit in the next diff.

Summary:
Basic "Fact" application with some storage, part of a daemon, and a control binary.
= Goals =
The general idea is that we have various statistics we'd like to compute, like the frequency of image macros, reviewer responsiveness, task close rates, etc. Computing these on page load is expensive and messy. By building an ETL pipeline and running it in a daemon, we can precompute statistics and just pull them out of "stats" tables.
One way to do this is just to completely hard-code everything, e.g. have a daemon that runs every hour which issues a big-ass query and dumps results into a table per-fact or per fact-group. But this has a bunch of drawbacks: adding new stuff to the pipeline is a pain, various fact aggregators can't share much code, updates are slow and expensive, we can never build generic graphs on top of it, etc.
I'm hoping to build an ETL pipeline which is generic enough that we can use it for most things we're interested in without needing schema changes, and so that installs can use it also without needing schema changes, while still being specific enough that it's fast and we can build useful stuff on top of it. I'm not sure if this will actually work, but it would be cool if it does so I'm starting pretty generally and we'll see how far I get. I haven't built this exact sort of thing before so I might be way off.
I'm basing the whole thing on analyzing entire objects, not analyzing changes to objects. So each part of the pipeline is handed an object and told "analyze this", not handed a change. It pretty much deletes all the old data about that thing and then writes new data. I think this is simpler to implement and understand, and it protects us from all sorts of weird issues where we end up with some kind of garbage in the DB and have to wipe the whole thing.
= Facts =
The general idea is that we extract "facts" out of objects, and then the various view interfaces just report those facts. This change has on type of fact, a "raw fact", which is directly derived from an object. These facts are concerete and relate specifically to the object they are derived from. Some examples of such facts might be:
D123 has 9 comments.
D123 uses macro "psyduck" 15 times.
D123 adds 35 lines.
D123 has 5 files.
D123 has 1 object.
D123 has 1 object of type "DREV".
D123 was created at epoch timestamp 89812351235.
D123 was accepted by @alincoln at epoch timestamp 8397981839.
The fact storage looks like this:
<factType, objectPHID, objectA, valueX, valueY, epoch>
Currently, we supprot one optional secondary key (like a user PHID or macro PHID), two optional integer values, and an optional timestamp. We might add more later. Each fact type can use these fields if it wants. Some facts use them, others don't. For instance, this diff adds a "N:*" fact, which is just the count of total objects in the system. These facts just look like:
<"N:*", "PHID-xxxx-yyyy", ...>
...where all other fields are ignored. But some of the more complex facts might look like:
<"DREV:accept", "PHID-DREV-xxxx", "PHID-USER-yyyy", ..., ..., nnnn> # User 'yyyy' accepted at epoch 'nnnn'.
<"FILE:macro", "PHID-DREV-xxxx", "PHID-MACR-yyyy", 17, ..., ...> # Object 'xxxx' uses macro 'yyyy' 17 times.
Facts have no uniqueness constraints. For @vrana's reviewer responsiveness stuff, we can insert multiple rows for each reviewer, e.g.
<"DREV:reviewed", "PHID-DREV-xxxx", "PHID-USER-yyyy", nnnn, ..., mmmm> # User 'yyyy' reviewed revision 'xxxx' after 'nnnn' seconds at 'mmmm'.
The second value (valueY) is mostly because we need it if we sample anything (valueX = observed value, valueY = sample rate) but there might be other uses. We might need to add "objectB" at some point too -- currently we can't represent a fact like "User X used macro Y on revision Z", so it would be impossible to compute macro use rates //for a specific user// based on this schema. I think we can start here though and see how far we get.
= Aggregated Facts =
These aren't implemented yet, but the idea is that we can then take the "raw facts" and compute derived/aggregated/rollup facts based on the raw fact table. For example, the "count" fact can be aggregated to arrive at a count of all objects in the system. This stuff will live in a separate table which does have uniqueness constraints, and come in the next diff.
We might need some kind of time series facts too, not sure about that. I think most of our use cases today are covered by raw facts + aggregated facts.
Test Plan: Ran `bin/fact` commands and verified they seemed to do reasonable things.

'phd status' should have a stable result when invoked multiple times.
Automatically removing PID files for dead daemons every time 'phd status' is
invoked prevents tools from noticing that a daemon has died if something
happens to invoke 'phd status' before the tool looks. This affects Puppet
noticably, since it probably runs the status command every half hour.
'phd status' may be invoked by tools (such as puppet) which need to make
automated decisions about whether to start/restart the daemon. To enable this,
'phd status' now exits with 0 if all daemons are running, 1 if no daemons are
running, and 2 if some (but not all) daemons are running.
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:
Certain types of things we should be storing in edges (notably, Task X depends on Task Y) should always be acyclic. Allow `PhabricatorEdgeEditor` to enforce this, since we can't correctly enforce it outside of the editor without being vulnerable to races.
Each edge type can be marked acyclic. If an edge type is acyclic, we perform additional steps when writing new edges of that type:
- We acquire a global lock on the edge type before performing any reads or writes. This ensures we can't produce a cycle as a result of a race where two edits add edges which independently do not produce a cycle, but do produce a cycle when combined.
- After performing writes but before committing transactions, we load the edge graph for each acyclic type and verify that it is, in fact, acyclic. If we detect cycles, we abort the edit.
- When we're done, we release the edge type locks.
This is a relatively high-complexity change, but gives us a simple way to flag an edge type as acyclic in a robust way.
Test Plan: Ran unit tests.

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.

Summary:
We have custom static resources.
We currently include them in Phabricator's celerity resource map which is causing some pain - we need to regenerate the file without our custom resources before pushing upstream, we need to discard our changes before pulling from upstream and we need to rebuild with our changes to run Phabricator.
This diff allows writing and reading the map in other location.
The plan is this - I will run `celerity_mapper.php` twice - once to build Phabricator-only resources (to push to upstream) and once to build Phabricator + ours resoruces to put in our directory.
Better solution would be to create a map just with our resources and read and combine it with Phabricator resources.
But it is complicated because we have dependencies on Phabricator resources.
Test Plan:
`celerity_mapper.php webroot`
`celerity_mapper.php webroot ../facebook/src/__celerity_resource_map__.php`
Delete Phabricator's celerity map, set 'celerity.resource-path' and successfully load Phabricator.

Summary:
- We currently write every PHID we generate to a table. This was motivated by two concerns:
- **Understanding Data**: At Facebook, the data was sometimes kind of a mess. You could look at a random user in the ID tool and see 9000 assocs with random binary data attached to them, pointing at a zillion other objects with no idea how any of it got there. I originally created this table to have a canonical source of truth about PHID basics, at least. In practice, our data model has been really tidy and consistent, and we don't use any of the auxiliary data in this table (or even write it). The handle abstraction is powerful and covers essentially all of the useful data in the app, and we have human-readable types in the keys. So I don't think we have a real need here, and this table isn't serving it if we do.
- **Uniqueness**: With a unique key, we can be sure they're unique, even if we get astronomically unlucky and get a collision. But every table we use them in has a unique key anyway. So we actually get pretty much nothing here, except maybe some vague guarantee that we won't reallocate a key later if the original object is deleted. But it's hard to imagine any install will ever have a collision, given that the key space is 36^20 per object type.
- We also currently use PHIDs and Users in tests sometimes. This is silly and can break (see D2461).
- Drop the PHID database.
- Introduce a "Harbormaster" database (the eventual CI tool, after Drydock).
- Add a scratch table to the Harbormaster database for doing unit test meta-tests.
- Now, PHID generation does no writes, and unit tests are isolated from the application.
- @csilvers: This should slightly improve the performance of the large query-bound tail in D2457.
