33020829b1 lfs_protocol: remove dependency on mononoke_types
Summary:
Mercurial wishes to use this crate, but pulling in mononoke_types brings way
too many dependencies. Since the only reason mononoke_types is brought in is
for the Sha256 type, let's just hardcode it to [u8; 32].

 * it's going to be useful immediately to store git hashes for configerator

 * it's going to be useful further down the line for real git support.

NOTE: I'm explicitly using the name `SHA1` all over the place to minimize the
confusion if we'll ever want to support other hashing schemes for git commits.

4a29fe400d mononoke/blobstore_healer: migrate replication lag polling to async / await
Summary:
The former implementation here was a little difficult to work with, and
resulted in a whole lot of cloning of closures, etc.

This updates the implementation to be a little simpler on the whole (async /
await is nicer for while loops, since you can use, well, loops)

It does slightly change a few parts of the behavior:

- The old implementation would wait for the replication lag duration. That's
  not really correct. As we've observed several time this weeks, replication
  lag usually drops quickly once it starts dropping. I.e. if the replication
  lag is 10 seconds, it doesn't take 10 seconds to catch up. This gets more
  important with big lag durations.
- I updated replication lag to be u64 instead of usize. usize doesn't really
  make sense for something that has absolutely nothing to do with our pointer
  size.

I also split out the logic for calculating how long we wait in a part that
cares about whether we are busy and one that cares about replication lag
(whereas the older one kinda mixed the two together). We wait for our own
throttling (i.e. sleep for a sec if we didn't do anything) before we wait for
replication lag, so the new behavior should have the desired behavior of:

- If we don't have much work to do, we sleep 1 second between each iteration
  (but if we do have work, we don't).
- No matter what, if we have replication lag, we wait until that passes before
  doing any work.

The old one did that too, but it mixed the two calculations together, and was
(at least in my opinion) kinda hard to reason about as a result.

be5d7343ce mononoke/blobstore_healer: check for replication lag _before_ starting work
Summary:
We had crahsloops on this (which I'm fixing earlier in this stack), which
resulted in overloading our queue as we tried to repeatedly clear out 100K
entries at a time, rebooted, and tried again.

We can fix the root cause that caused us to die, but we should also make sure
crashloops don't result in ignoring lag altogether.

Also, while in there, convert some of this code to async / await to make it
easier to work on.

6da3dc939a mononoke/blobstore_sync_queue: delete in smaller batches
Summary:
Our blobstore_sync_queue selects entries with a limit on the number of unique
keys it's going to load. Then, it tries to delete them. However, the number of
entries might be (much) bigger than the number of keys. When we try to delete
them, we time out waiting for MySQL because deleting 100K entries at once isn't
OK.

This results in crashlooping in the healer, where we start, delete 100K
entries, then time out.

This is actually double bad, because when we come back up we just go wihhout
checking replication lag first, so if we're crashlooping, we disregard the
damage we're doing in MySQL (I'm fixing this later in this stack).

So, let's be a bit more disciplined, and delete keys 10K at a time, at most.

    - https://docs.rs/tokio-codec/0.1/tokio_codec/trait.Encoder.html
    - https://docs.rs/tokio-codec/0.1/tokio_codec/trait.Decoder.html

- 0.2 codecs use bytes 0.5
    - https://docs.rs/tokio-util/0.2/tokio_util/codec/trait.Encoder.html
    - https://docs.rs/tokio-util/0.2/tokio_util/codec/trait.Decoder.html

Since we can't possibly do a coordinated atomic upgrade of tokio, we'll be straddling bytes versions during the migration period. This relies on the adapters added in D19919402.

This is a pretty big footgun, so let's fix it. As it turns out, we already have
a Tokio compat runtime in process, which is (was — this is mostly in SCS now)
used for Thrift calls.

So, let's use that runtime to call into Mononoke code. This ensures we don't
get any nasty surprises of the panicky kind at runtime.

16384599a8 mononoke (+ rust/shed/async_unit): update async_unit to expect async fn's
Summary:
This allows code that is being exercised under async_unit to call into code
that expects a Tokio 0.2 environment (e.g. 0.2 timers).

Unfortunately, this requires turning off LSAN for the async_unit tests, since
it looks like LSAN and Tokio 0.2 don't work very well together, resulting in
LSAN reporting leaked memory for some TLS structures that were initialized by
tokio-preview (regardless of whether the Runtime is being dropped):
https://fb.workplace.com/groups/rust.language/permalink/3249964938385432/

Considering async_unit is effectively only used in Mononoke, and Mononoke
already turns off LSAN in tests for precisely this reason ... it's probably
reasonable to do the same here.

The main body of changes here is also about updating the majority of our
changes to stop calling wait(), and use this new async unit everywhere. This is
effectively a pretty big batch conversion of all of our tests to use async fns
instead of the former approaches. I've also updated a substantial number of
utility functions to be async fns.

A few notable changes here:

- Some pushrebase tests were pretty flaky — the race they look for isn't
  deterministic. I added some actual waiting (using pushrebase hooks) to make
  it more deterministic.  This is kinda copy pasted from the globalrev hook
  (where I had introduced this first), but this will do for now.
- The multiplexblob tests don't work at all with new futures, because they call
  `poll()` all over the place. I've updated them to new futures, which required
  a bit of reworking.
- I took out a couple tests in async unit that were broken anyway.

6a1358467e mononoke: change how we generate filenodes for octopus merges
Summary:
In the next diff I'm going to refactor BlobRepo::get_manifest_from_bonsai()
function and remove IncompleteFilenodes structure. While doing so I noticed
that the behaviour of get_manifest_from_bonsai() and FilenodesOnlyPublic is
different with regards to generating hg filenodes for octopus merges. In
particular, get_manifest_from_bonsai() at the moment doesn't generate filenodes
for paths that came from stepparents, but FilenodesOnlyPublic does generate
them.

I'd say both of this approach are equally reasonable, however let's try to
preserve the behaviour

To make the scope of the `EdenApiContext` more clear (namely, that unlike the other contexts, this one persists for the entirety of the server's execution), let's rename this to `EdenApiServerContext`. This mirrors the naming convention for these contexts used in the LFS server.

41216b7530 mononoke/fastreplay: handle JSON-encoded strings in command args
Summary:
If we e.g. a getpack for path like "foo\"bar", then we can't decode it into a
`&str` because we need to allocate a new `String` to hold it. At the same time,
if the path is "foo bar", then having a reference into the JSON we received is
nicer.

Right now, we expect a `&str`, so the latter case. But, if we find command args
from the first case, we can't deserialize them. To fix this, let's use
`Cow<...>`, which lets us either have a referenced or an owned string.

Also, let's add tests to confirm this works.

d39eea991b blobrepo: don't fetch Hg Changeset IDs sequentially
Summary:
Fetching things from MySQL sequentially in a buffered fashion is a bad
practice, since we might end up saturating the underlying MySQL pool, and
starving other MySQL  clients.

Instead, let's make fewer, bigger queries.

ce8b9a0fbe getbundle_response: don't fetch Hg Changeset IDs sequentially
Summary:
Fetching things from MySQL sequentially in a buffered fashion is a bad
practice, since we might end up saturating the underlying MySQL pool with a lot
of requests. Doing so will result in other queries being delayed as they wait
behind our batch of queries, which results in higher dispatch latency.

Instead, let's make fewer, bigger queries. Also, while we're in here, let's
update blobrepo to have an up-to-date comment.

c8a4ba5dac mononoke: commit sync thrift api
Summary:
This is the api that will be used by Sandcastle to remap a commit from one repo
to another.
Previously the implementation api was just looking in the commit mapping table,
but that's not enough - draft commit cloud commits are not in this table, so we
actually need to sync them.

There's a caveat though - we allow syncing public commits from a large repo to
a small repo, but not the other way around. Comment in the code has more info
about it.
