64472dd7b8 Adding Ponder-related files.
Summary:
Ponder is similar in spirit to the Wiki tool, but uses a Q&A
format and up/downvotes to signal user sentiment. Popular
questions are moved to the top of the feed on a 5-minute
cycle based on age (younger is better) and vote count (higher
is better).

Pre-apologies for noob diff.

Test Plan:
- `./bin/phd list` Should include `PonderHeatDaemon`; phd launch it
  if necessary.

- Navigate to /ponder/ ; observe sanity when adding questions,
  voting on them, and adding answers.

- Confirm that questions and answers are linkable using Q5 / Q5#A5 formatted object links.

- Confirm that searching for Ponder Questions works using built-in
  search.

Feedback on code / schema / whatever organization very welcome.

8a4c08b01d Allow commits to be associated with projects and associated goodies
Summary:
- Commit detail view
 - List of projects
 - "edit" action which takes the user to a simple form where they can only add / remove projects.
-  Integrated the project relationship into the commit search indexer
 - fixed a bug from D790; it seems you must select the column if you're going to join against it later. Without this change searching for author or projectfails 100% for me.

Test Plan: added and removed projects. verified appropriate projects showed up in detail and edit view. searched for commits by project and found the ones I was supposed to...!

358baf1b3a Improve the flag.* Conduit methods
Summary:
 - Put the code to generate informational dicts about flags into the
   base class.
 - Update flag.delete to accept an object PHID in order to delete the
   flag on that object, since currently the model is that each object
   may have at most one flag, and each flag has exactly one object,
   although the former is not enforced.
 - Add flag.edit, which creates or updates a flag, optionally with the
   given color and note.

Test Plan:
Spend endless hours repeatedly running arc call-conduit and
arc flag.

bbe2063443 [NO CLUE WHAT I'M DOING] Add an Elasticsearch engine
Summary:
I have no idea what I'm doing, but here's part of an elasticsearch engine. These things work:

  - Indexing stuff (??)
  - Searching for text/type?
  - Reconstructing things??

All the complicated stuff doesn't work. I'm having a hard time figuring out the best way to model things because elasticsearch's documentation is not exactly the most complete or illuminating.

@amckinley, does this look sane-ish so far? Particularly, the /phabricator/<type>/<phid>/ URI scheme and how I've set up the relationships and fields in the documents?

How should I model the relationship and field queries? I want, like, an "equal" query but it seems like I've got "text" or "term" to work with and neither are exact match? And "term" doesn't consider PHIDs to be terms since they have hyphens in them?

I'll keep kind of slogging my way forward here but if you have valuable wisdom to share it would probably get me to a better end state much faster. The whole query construction phase is pretty much black magic to me.

5ee1341b97 Be able to search for Differential and other short strings
Summary:
I wanted to search for D1234 in texts of other documents.
But search tool always redirects me.

I've left the redirect behavior for simple search forms (header and home) and removed it from full search form.

I don't consider this complete because the first result in search for D1234 should be of course D1234 which is not the case currently.
I am not sure how to solve it:

- We can display a special result in this case.
- We can index the documents so that they will be searchable also for short strings.

I tend to use the first solution because revisions can be truncated at arbitrary length (rX1f1f1f should display revision rX1f1f1f1f1f1f1f).

Test Plan: Search for D1234, rX123, T4.

a5f8846f47 Use a unique random key to identify queries, not a sequential ID
Summary:
We save search information and then redirect to a "/search/<query_id>/" URI in
order to make search URIs short and bookmarkable, and save query data for
analysis/improvement of search results.

Currently, there's a vague object enumeration security issue with using
sequential IDs to identify searches, where non-admins can see searches other
users have performed. This isn't really too concerning but we lose nothing by
using random keys from a large ID space instead.

  - Drop 'authorPHID', which was unused anyway, so searches can not be
personally identified, even by admins.
  - Identify searches by random hash keys, not sequential IDs.
  - Map old queries' keys to their IDs so we don't break any existing bookmarked
URIs.

Test Plan: Ran several searches, got redirected to URIs with random hashes from
a large ID space rather than sequential integers.

84ea5c53e4 Kill PhabricatorFileURI
Summary:
we used to need this function for security purposes, but no longer need
it.   remove it so that some call sites can be optimized via smarter data
fetching, and so the whole codebase can have one less thing in it.

Test Plan:
verified the images displayed properly for each of the following
- viewed a diff with added images.
- viewed a user feed
- viewed a user profile
- viewed all image macros
- viewed a paste and clicked through "raw link"
weakness in testing around proxy files and transformed files.  not sure what
these are.  changes here are very programmatic however.

2a29a51080 Deploy new ArcanistManyWordsAboutDifferentialConstants class from D1328 into
Phabricator

Summary: ...this breaks without D1328.   Used good ole "codemod" to do this
work, with lots of manual edits around 80 chars.

Test Plan: clicked around phabricator tool suite, particular differential, a
bunch

c97fcd12bc Share Revision/Task attaching code
Summary:
We have this code in two places; split it into an editor class so we can share
it.

This also fixes some probems with this field not //detaching// tasks properly.

Test Plan:
  - Created a revision with no attached tasks.
  - Attached it to a task.
  - Updated it.
  - Detached it.
  - Used web UI to attach/detach tasks/revisions.
