02c3200867 Respond more gracefully when a git push deletes a nonexistent ref
Summary:
Fixes T5534. If you `git push origin :refs/tags/doesnotexist` (for some non-existing tag), we get a change where both the old and new refs are empty.

We incorrectly call this an "add", because the old ref is empty. Instead, call this a "delete", but skip the logic which would normally mark it dangerous.

(Possibly we should just reject these outright, but Git allows them, so stick with that for now.)

Test Plan:
Pushed nonexistent refs:

```
  $ git push origin :refs/tags/doesnotexist
  remote: warning: Allowing deletion of corrupt ref.
  To ssh://dweller@localhost/diffusion/POEMS/
   - [deleted]         doesnotexist
  $
```

5660684d7f Never use "{branches}" in Mercurial
Summary:
Fixes T5304. Mercurial features a "{branches}" template keyword, documented as:

```
    branches      List of strings. The name of the branch on which the
                  changeset was committed. Will be empty if the branch name
                  was default.
```

At some time long in the past, I misinterpreted this to mean "list of branches where the branch head is a descendant of the commit". It is more like "list of zero or one elements, possibly containing the name of the branch the commit was originally made to, if that branch was not 'default'".

In fact, it seems like this is because a //very// long time in the past, Mercurial worked roughly like I expected:

> Ages ago (2005), we had a very different and ultimately unworkable
> approach to named branches that worked vaguely like .hgtags and allowed
> multiple branch names per revision.

http://marc.info/?l=mercurial-devel&m=129883069414855

This appears to be deprecated in modern Mercurial (it's not in the modern web documentation) although I can't find a commit about it so maybe that's just a documentation issue.

In any case, `{branches}` seems to never be useful: `{branch}` provides the same information without the awkward "default-if-empty" case.

Switch from `{branches}` to either `{branch}` (where that's good enough, notably in the hook engine) or `(descendants(%s) and head())`, which is equivalent to `--contains` in Git.

This fixes pushing to branches with spaces in their names, and makes the "Branches" / "Contains" queries moderately more consistent.

Test Plan:
  - Pushed to a Mercurial branch with a space in it.
  - Viewed list of branches in a Mercurial repository.
  - Viewed containing branches of a Mercurial commit in Diffusion.

66af361f10 Fix a Mercurial issue where split heads would be detected incorrectly
Summary: Ref T5197. When searching for split branch heads, we incorrectly consider descendant heads of other branches. This can cause us to detect a split tip when one does not exist (the old tip is the branch tip, but other descendant heads exist). Instead, consider only heads on the same branch.

Test Plan:
Repro is something like this:

  - `hg update default`
  - `hg branch branch1; hg commit ...`
  - `hg push`
  - `hg update default; hg commit ...`
  - `hg push` - Previously, we would find the head of `branch1` and incorrectly account for it as a head of `default`.

1aad40b7bf Allow users to receive email about pushes via Herald
Summary:
Fixes T4677. Implements a "send an email" pre-receive action, which sends push summaries.

For use cases where features are often pushed as a large number of commits (e.g., checkpoint commits are retained), using commit emails means users get a ton of email. Instead, this allows you to get an email about a push, which summarizes what changed.

Overall, this is basically the same as commit email, but more suitable for some workflows.

Test Plan:
Wrote some rules, then made a bunch of pushes. Got email like this:

a5f55d506f Provide a real object ("PhabricatorRepositoryPushEvent") to represent an entire push transaction
Summary:
Ref T4677. Currently, we record individual actions in a push as PhabricatorRepositoryPushLogs, but tie them together only loosely with a `transactionKey`.

Provide a real PushEvent object, and move some of the denormalized fields to it. This primarily just gives us more robust infrastructure for building, e.g., email about pushes, for T4677, since we can act on real PHIDs rather than passing awkward identifiers around.

Test Plan:
  - Performed migration.
  - Looked at database for consistency.
  - Browsed/queried push logs.
  - Pushed a bunch of stuff.

Summary:
Fixes T4276. This adds "Change is enormous" to pre-commit content rules so we can, e.g., just reject these and not worry about them elsewhere.

Also, use the same numeric limits across the mechanisms so there's a consistent definition of an "enormous" changeset.

Test Plan:
  - Set enormous limit to 15 bytes, pushed some changes, got blocked by a rule.
  - Set it back, pushed OK.

972dfa7bfc Add 'hook.d/' directories to SVN and Git repositories for custom hooks
Summary:
Fixes T4189. Ref T4151. Allows repositories to have additional custom hooks for operations which can't be expressed with Herald (one such operation is lint).

This adds only local hook directories, since they're easier to use with existing hooks than global directories. I might add global directories eventually.

This doesn't support Mercurial since we have no demand for it and it's more complicated (we lose compatibility and power by just dropping a `hooks.d/` somewhere).

Test Plan:
  - Pulled hosted SVN and Git repos to verify the hook directories generate correctly.
  - Added a variety of hooks to the hook directories (echo + pass, fail).
  - Pushed commits and verified the hooks fired (output expected info, or failed).
  - Verified push log reflected the correct error code ("3", external) and detail ("nope.sh") when rejecting.

6daa2b6c2e Fix a commit hook issue with the initial commit to Mercurial repositories
Summary:
Fixes T4257. The `hg heads` command exits with an error code and no output in an empty repository.

Just ignore the error code: we don't have a great way to distinguish between errors, and we ran another `hg` command moments before, so we have at least some confidence it isn't a PATH sort of thing.

Test Plan: Created a new Mercurial repository and pushed to hit the error in T4257. Applied this fix and got a clean push with an accurate push log.

Summary:

In future diffs, everything will generate PushLogs and we can hand those off to Herald.

caa6fdf56d Add a basic push log for recording repository push events
Summary:
Ref T4195. This log serves two purposes:

  - It's a log, so you can see what happened. Particularly, in Git/Hg, there is no other way to tell:
    - Who //pushed// a change (vs committed / authored)?
    - When was a change pushed?
    - What was the old value of some tag/branch before someone destroyed it?
  - We can hand these objects off to Herald to implement pre-commit rules.

This is a very basic implementation, but gets some data written and has a basic UI for it.

With flag on and off, performed various safe and dangerous pushes.

632e1ceda6 Do the heavy lifting for git commit hooks
Summary:
Ref T4189. This doesn't add any rules yet, but does all the heavy lifting to figure out what's changed and put it in a consuamble (if somewhat ad-hoc) datastructure, which lists all the ref and tag modifications and all the new commits in a consistent way.

From here, it should be fairly straightforward to add top-level rules (e.g., ff pushes only).

Test Plan: Output is huge, see comments.

Summary: Ref T4189. Fixes T2066. Mercurial has a //lot// of hooks so I'm not 100% sure this is all we need to install (we may need separate hooks for tags/bookmarks) but it should cover most of what we're after at least.

Test Plan:
  - `bin/repository pull`'d a Mercurial repo and got a hook install.
  - Pushed to a Mercurial repository over SSH and HTTP, with good/bad hooks. Saw hooks fire.

017d6ccd07 Support SVN pre-commit hoooks
Summary:
Ref T4189. This adds SVN support, which was a little more messy than I though. Principally, we can not use `PHABRICATOR_USER` for Subversion, because it strips away the entire environment for "security reasons".

Instead, use `--tunnel-user` plus `svnlook author` to figure out the author.

Also fix "ssh://" clone URIs, which needs to be "svn+ssh://".

Test Plan:
  - Made SVN commits through the hook.
  - Made Git commits, too, to make sure I didn't break anything.

618b5cbbc4 Install pre-commit hooks in Git repositories
Summary:
Ref T4189. T4189 describes most of the intent here:

  - When updating hosted repositories, sync a pre-commit hook into them instead of doing a `git fetch`.
  - The hook calls into Phabricator. The acting Phabricator user is sent via PHABRICATOR_USER in the environment. The active repository is sent via CLI.
  - The hook doesn't do anything useful yet; it just veifies basic parameters, does a little parsing, and exits 0 to allow the commit.

Test Plan:
  - Performed Git pushes and pulls over SSH and HTTP.
