Summary:
Ref T13600. When migrating observed repositories between cluster services, impact can be better controlled by fetching a copy of the repository on the target host before clusterizing it.
In particular, in the Phacility cluster, migrations are generally from one shared shard to one dedicated shard. It's helpful to perform these migrations synchronously without waiting for the cluster to sync in the background (helpful in the sense that there are fewer steps and fewer commands to run).
This supports an "--observe" mode to the internal "bin/services load-repository" workflow, which transfers repository data by refetching it from the remote rather than by getting it from the older host. This fetch occurs before cluster configuration is adjusted.
Test Plan: Ran locally as a sanity check, will apply in production.

Summary:
Ref T13591. Currently, the "IMPORTED_PERMANENT" flag (previously "IMPORTED_CLOSEABLE", until D21514) flag is set by using the result of "shouldPublishRef()".
This method returns the wrong value for the flag when there is a repository-level reason not to publish the ref (most commonly, because the repository is currently importing).
Although it's correct that commits should not be published in an importing repository, that's already handled in the "PublishWorker" by testing "shouldPublishCommit()". The "IMPORTED_PERMANENT" flag should only reflect whether a commit is reachable from a permanent ref or not.
- Move the relevant logic to a new method in Publisher.
- Fill "IMPORTED_PERMANENT" narrowly from "isPermanentRef()", rather than broadly from "shouldPublishRef()".
- Deduplicate some logic in "PhabricatorRepositoryRefEngine" which has the same intent as the logic in the Publisher.

Ref T13552. When a previously discovered commit becomes reachable from a permanent ref, we re-queue workers to update it. However, the commit may already be marked as "published", so the publish worker may do nothing.
It would perhaps be simpler to not mark the commit as published when it isn't reachable from a permanent ref, but this is tricky because the flag is also part of the "imported / all steps" state (see T13580).
Until that can be cleaned up, just clear the flag.

Summary:
Ref T13538. See PHI1739. Synthetic Git commits with no author and/or no commit message currently extract `null` and then fail to parse.
Ideally, we would carefully distinguish between `null` and empty string. In practice, that requires significant schema changes (these columns are non-nullable and have indexing requirements) and these cases are degenerate. These commits are challenging to build and can not normally be constructed with `git commit`.
At least for now, merge the `null` cases into the empty string cases so we can survive import.
Test Plan:
- Constructed a commit with no author and no commit message using the approach described in T13538; pushed and parsed it.
- Before: fatals during identity selection and storing the commit message (both roughly NULL inserts into non-null columns).
- After: clean import.

See PHI1688. If many refs with a large amount of shared ancestry are deleted from a repository, we can spend much longer than necessary marking their mutual ancestors as unreachable over and over again.
For example, if refs A, B and C all point near the head of an obsolete "develop" branch and have about 1K shared commits reachable from no other refs, deleting all three refs will lead to us performing 3,000 mark-as-unreachable operations (once for each "<ref, commit>" pair).
Instead, we can stop exploring history once we reach an already-unreachable commit.

- Destroyed 7 similar refs simultaneously.
- Ran `bin/repository refs`, saw 7 entries appear in the `oldref` table.

Fixes T13448. We currently "git clone" to initialize repositories, but this will fetch too many refs if "Fetch Refs" is configured.
In modern Phabricator, there's no apparent reason to "git clone"; we can just "git init" instead. This workflow naturally falls through to an update, where we'll do a "git fetch" and pull in exactly the refs we want.
Test Plan:
- Configured an observed repository with "Fetch Refs".
- Destroyed the working copy.
- Ran "bin/repository pull X --trace --verbose".
- Before: saw "git clone" pull in the world.

We don't want this when we pass a narrow refspec because of "Fetch Refs" configuration. Tell Git that we only want the refs we explicitly passed.
Note that this doesn't prevent us from fetching tags (if the refspec specifies them), it just stops us from fetching extra tags that aren't part of the refspec.
Test Plan:
- Ran "bin/repository pull X --trace --verbose" in a repository with a "Fetch Refs" configuration, saw only "master" get fetched (previously: "master" and reachable tags).

Summary:
Ref T13448. When "Fetch Refs" is configured:
- We switch to a narrow mode when running "ls-remote" against the local working copy. This excludes surplus refs, so we'll incorrectly detect that the local and remote working copies are identical in cases where the local working copy really has surplus refs.
- We rely on "--prune" to remove surplus local refs, but it only prunes refs matching the refspecs we pass "git fetch". Since these refspecs are very narrow under "Fetch Only", the pruning behavior is also very narrow.
Instead:
- When listing local refs, always list everything. If we have too much stuff locally, we want to get rid of it.
- When we identify surplus local refs, explicitly delete them instead of relying on "--prune". We can just do this in all cases so we don't have separate "--prune" and "manual" cases.
Test Plan:
- Created a new repository, observed from a GitHub repository, with many tags/refs/branches. Pulled it.
- Observed lots of refs in `git for-each-ref`.
- Changed "Fetch Refs" to "refs/heads/master".
- Ran `bin/repository pull X --trace --verbose`.
On deciding to do something:
- Before: since "master" did not change, the pull declined to act.
- After: the pull detected surplus refs and deleted them. Since the states then matched, it declined further action.
On pruning:
- Before: if the pull was forced to act, it ran "fetch --prune" with a narrow refspec, which did not prune the working copy.
- After: saw working copy pruned explicitly with "update-ref -d" commands.
Also, set "Fetch Refs" back to the default (empty) and pulled, saw everything pull.

Summary: Ref T13440. This feature is used in only one interface which I'm about to rewrite, so throw it away.
Test Plan: Grepped for all affected symbols, didn't find any hits anywhere.

Summary:
Fixes T13435. If you move Phabricator or copy data from one environment to another, the repository URI index currently still references the old URI, since it writes the URI as a plain string. This may make "arc which" and similar workflows have difficulty identifying repositories.
Instead, store the "phabricator.base-uri" domain and the "diffusion.ssh-host" domain as tokens, so lookups continue to work correctly even after these values change.
Test Plan:
- Added unit tests to cover the normalization.
- Ran migration, ran daemons, inspected `repository_uriindex` table, saw a mixture of sensible tokens (for local domains) and static domains (like "github.com").
- Ran this thing:
```
$ echo '{"remoteURIs": ["ssh://git@local.phacility.com/diffusion/P"]}' | ./bin/conduit call --method repository.query --trace --input -
Reading input from stdin...
>>> [2] (+0) <conduit> repository.query()
>>> [3] (+3) <connect> local_repository
<<< [3] (+3) <connect> 555 us
>>> [4] (+5) <query> SELECT `r`.* FROM `repository` `r` LEFT JOIN `local_repository`.`repository_uriindex` uri ON r.phid = uri.repositoryPHID WHERE (uri.repositoryURI IN ('<base-uri>/diffusion/P')) GROUP BY `r`.phid ORDER BY `r`.`id` DESC LIMIT 101
<<< [4] (+5) <query> 596 us
<<< [2] (+6) <conduit> 6,108 us

```
Note the `WHERE` clause in the query normalizes the URI into "<base-uri>", and the lookup succeeds.

Summary: Fixes T13430. Provide more information about repositories in "diffusion.repository.search".
Test Plan: Used API console to call method (with new "metrics" attachment), reviewed output. Saw new fields returned.

Summary:
Depends on D20853. See PHI1474. If the list of "--not" refs is sufficiently long, we may exceed the maximum size of a command.
Use "--stdin" instead, and swap "--not" for the slightly less readable but functionally equivalent "^hash", which has the advantage of actually working with "--stdin".
Test Plan: Ran `bin/repository refs ...` with nothing to be done, and with something to be done.
Differential Revision: https://secure.phabricator.com/D20854
Summary: See PHI1474. This query can become large enough to exceed reasonable packet limits. Chunk the query so it is split up if we have too many identifiers.
Test Plan: Ran `bin/repository refs ...` on a repository with no new commits and a repository with some new commits.
