194dc40672 Add a meta-application
Summary:
  - Adds a new "Applications" application.
  - Builds an application list via application config instead of via hard-coding, so we can move toward better concepts of installing/uninstalling applications, etc.
  - Applications indicate that they need attention with notice counts and brief status messages rathern than 50 giant tables of all sorts of app data.

I want to try replacing the home screen with this screen, pretty much. Not sure if this is totally crazy or not. What does everyone else think?

Test Plan: Will add screenshots.

04fafdb75c Make columns in flag view not squish each other
Summary:
Unlike (all? most?) other tables, the flag table has two wide
columns: the object name and the flag note. This fiddles with the
classes so neither gets squished too much by the other.

This is kind of a hack and I don't even know if it's cross-browser
compatible because I only have WebKit here. But maybe it's fine.

Test Plan:
View Differential home page while changing revision names and
flag notes to weird things.

8e5189b439 Add a Delete link to Differential inline comment previews
Summary:
This lets you delete inlines from the preview at the bottom of
the page, instead of hunting for them through the diffs.

There is not yet a keyboard shortcut.

The mechanism for updating the inlines in the diffs is kind of a hack
and I'm sure I'm special-casing way too much, but at least it works.

Test Plan:
Load revision with many diffs. Create inlines all over the

9a19cfb9de Limit amount of chart data passed to browser
Summary:
Firefox has a limit of ~500,000 elements which can be passed in literal array.
This amount of data is meaningless anyway because even Retina displays don't have such resolution.

Limit the amount of data to mitigate browser limitations and also reduce the page size.
Ensure that first and last element is passed.

I considered also reducing the granularity to days but I want new repositories to have nice precise graph.

88caa45854 Save daemon state to database
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.

6e1f5e353a Abbreviate author/committer in Diffusion directory views
Summary:
The tables are currently kind of wide, and the emails for
non-recognized users seem like the least useful parts, so I put them in
tooltips so they're only visible if you want them. On the other hand, it
means you can only view one at a time, and if you're on mobile you can't
see them at all. Overall, not sure whether this is a good idea.

Test Plan:
Load Diffusion pages with some recognized and some
unrecognized users. Hover over the latter and see that emails appear.

a476e5c08d Include symbols in main typeahead
Summary:
  - Include symbols in main typeahead results.
  - Simplify the symbol query a bit and extend PhabricatorOffsetPagedQuery. There was some stuff around language ranking that I got rid of, I think the theory there was that mapping file extensions to languages might not work in general but I think it works fine in practice, and we have more config stuff now around guessing languages and getting the mappings right.
  - Make it easier to debug the typeahead by showing the results in page format for non-ajax requests.
  - When we have too many results, show only the top few of each type.

Depends on D3116, D3117

Test Plan: Used typeahead, got symbols in results. Hit endpoint with non-ajax, got useful debug view.

c8afc741fa Add support for placeholders
Summary:
Support placeholder text for inputs. We currently don't use this because it requires JS and doesn't degrade (no JS means you have zero idea what the input is for if it isn't separately labeled) but there are some cases where intent is obvious from context (for example, the search input in the menu bar, which is fairly obvious on its own and will soon have a magnifying glass icon) and in such cases it's much prettier and saves a bunch of space over an explicit label. Add a behavior so we can add placeholders where they make sense.

This implementation is somewhat sanity-checked agianst the two jQuery placeholder implementations I was able to google:

https://github.com/danielstocks/jQuery-Placeholder/
https://github.com/mathiasbynens/jquery-placeholder

Since we don't currently have any uses cases, I haven't included support for making JS access to the `value` work, for password inputs, or for dynamically altering the placeholder.

Test Plan: Played around with the placeholder in the UI example in various browsers and couldn't break it.

7c9c3284ed Add the ability to append to $PATH, for when we shell out to system binaries.
Summary:
In some cases, we shell out to things (like Pygments for syntax highlighting).
However, on cloud servers or shared web servers, those binaries aren't always
installed system-wide.

This patch allows for appending to the environment variable $PATH, to look for
other, non-default places for these binaries.

Test Plan:
* Copied the patch over to a test OpenShift instance and applied it.
* Added the path to my local copy of Pygments (pygmentize wasn't available on the system)

486f7c1e8e Add aggregated facts to the Facts application
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.

Test Plan: Ran the engines and got some aggregated facts about other facts.

7c934e4176 Add a basic "fact" application
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.

14e3e5ccfd Provide user option for disabling diffusion symbol cross-references
Summary: Some people don't like these, so they should be able to turn them off.

Test Plan:
Toggled the setting on and off; loaded a page in diffusion and differential
that should have symbol cross-references, and saw that they weren't linked
when I had the setting disabled. I also checked that the symbols are still
linked when the setting hasn't been touched.
