Summary:
This module previously used to handle deciding how a particular module should
be imported if it had multiple versions (e.g., pure Python or native).
However, as of D18819680 it was changed to always import the native C version.
Lets go ahead and remove it entirely now. Using `policy.importmod` simply
makes it harder for type checkers to figure out the actual module that will be
used.
The only functionality that `policy.importmod()` still provided was verifying
that the module contained a "version" field that looked like what was
expected. In practice these version numbers are not bumped often, so this
doesn't really seem to provide much value in checking that we imported the
correct version that we expected to be shipped with this release.

This moves the build rules for the extensions in mercurial/cext into a TARGETS

This will allow us to start writing `*.pyi` files that contain type
information for these modules, and store them alongside the corresponding `.c`
files. By having the build rules in the top-level `eden/scm` directory we
would have needed to keep the `.pyi` files for these modules directly in the
`eden/scm` directory instead, as the namespace for the `pyi` files is assumed
to be the basemodule plus their path relative to the TARGETS file.

Summary:
This error handling can be extremely slow: calling `self.node()` can end up
triggering a linkrev scan of the changelog, which can take over 5 minutes.
If we did want to add this back in the future we would need some sort of API
on `filectx` to try and get the node ID only if it was cheap, and that would
fail fast if this is using remotefilelog and trying to get the node ID will
require scanning the changelog.
Note that KeyError can occur fairly regularly when invoked in long-lived
commands like `hg debugedenimporthelper`. If we are asked about data in a new
commit that was added since this repository was originally opened a KeyError
will be thrown here (in which case `debugedenimporthelper` will call
`repo.invalidate()` and then retry).

this simplification should help in formalizing the hierarchy of files/folders.
It will look like the following:

<root dir>/indexedlog*: for the indexedlog
<root dir>/foobar: for a hypothetical foobar store
For manifests, <root dir> will therefore be: <store dir>/manifests. The
unfortunate part is that the current tree data lives under
<store dir>/packs/manifests. As packfiles will be replaced, this small
discrepency is acceptable.

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.

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.

Summary:
On Windows, there are *two* 8-bit encodings for each process.
* The ANSI code page is used for all `...A` system calls, and this is what
Mercurial uses internally. It can be overridden using the `--encoding`
command line option.
* The OEM code page is used when outputing to the console. Mercurial has no
concept of this, and instead renders to the console using the ANSI code page,
which results in mojibake like "Θ" instead of "é".
Add the concept of an `outputencoding`. If this differs from `encoding`, we
convert from the local encoding to the output encoding before writing to the
console.
On non-Windows platforms, this defaults to the same encoding as the local encoding,
so this is a no-op unless `--outputencoding` is manually specified.
On Windows, this defaults to the codepage given by `GetOEMCP`, causing output
to be converted to the OEM codepage before being printed.
For ordinary strings, the local encoded version is wrapped by `localstr` if the
encoding does not round-trip cleanly. This means the output encoding works
even if the character is not represented in the local encoding.
Unfortunately, the templater is not localstr-clean, which means strings can get
flattened down to the local encoding and the original code points are lost. In
this case we can only output characters which are in the intersection of the
encoding and the output encoding.
Most US English Windows systems use cp1252 for the ANSI code page and cp437 for
the OEM code page. These both contain many accented characters, so users with
accented characters in their names will now see them correctly rendered.
All of this only applies to Python 2.7. In Python 3, everything is Unicode,
the `--encoding` and `--outputencoding` options do nothing, and it just works.

ImportError earlier when we can't even find this file, and the code will still
fall back to using `fb-re2`.

Summary: Add a `RequestContext` type that stores per-request state, along with a `Middleware` implementation that injects a `RequestContext` into Gotham's `State` object for each request. This is essentially a stripped-down version of the `RequestContextMiddleware` used in the LFS server. Given that the RequestContext contains application-specific functionality, this Middleware lives alongside the rest of the EdenAPI server code rather than in the `gotham_ext` crate (where all of the generic Middleware lives).

Summary:
Currently if derivation of a particular derived data type is disabled, but a
client makes a request that requires that derived data type, we will fail with
an internal error.
This is not ideal, as internal errors should indicate something is wrong, but
in this case Mononoke is behaving correctly as configured.
Convert these errors to a new `DeriveError` type, and plumb this back up to
the SCS server. The SCS server converts these to a new `RequestError`
variant: `NOT_AVAILABLE`.

Summary:
Not being able to prefetch draft parent trees should not be considered as a
fatal error.
This code path is causing trouble with narrow-heads clone:
1. Streaming clone. The client gets a changelog.
2. The client runs "pull" to get new commits. The prefetchdraftparents code path runs.
3. The client has stale remote names, and public() is lagging. `prefetchdraftparents`
will try to fetch trees at the old master, but the repo is not configured properly.
That causes a stacktrace like:

Summary:
Commit messages and extras can be unbounded in size. This can cause problems if users create commits with exceptionally large messages or extras. Mercurial will commit these to the changelog, increasing its size. On Mononoke, large commit messages may go over the cacheing threshold, resulting in poor performance for requests involving these commits as Mononoke will need to reload on every access.
Commit messages should not usually be that large. Mostly likely it will happen by accident, e.g. through use of `hg commit -l some-large-file`. Prevent this from happening by accident by adding configuration for soft limits when creating commits.
If a user really does need to create a commit with a very large message or extras, they can override using the config option.

Summary:
Sometimes the treestate points to an unknown commit (ex. aborted transaction
might strip commits). While `debugrebuilddirstate -r HASH --hidden` is able to
fix it, it is too slow.
This diff adds treestate repair logic to the `doctor` command. It scans through
the treestate files, find a most recent `Root` entry with `p1` pointing to a
known commit.
This can be much faster than `debugrebuilddirstate` in some cases, because the
watchman clock might still be valid, and the NEED_CHECK file list might still
be small. In that case, `status` can still be fast.
Since treestate atomically updates all information needed for `status`
calculation (parents, need-check-files (or, "non-normal files"), watchman-clock
(only with fsmonitor), and stat for clean files). Reverting to a previous state
is still atomic. Correctness-wise, this is equivalent to aborting a "large"
transaction, and restoring treestate data to the state before the transaction.
It should be consistent, and the next `status` call won't mis-report files like
the dangerous `debugsetparents` command.

This is better than fixcorrupt because `hg doctor` does not require a repo

check if a commit hash is known by changelog or not.

Summary:
Right now, Mononoke code in apiserver executes on Actix's runtime. That's a 0.1
runtime, which means that we're calling into code that might just fail if e.g.
it uses Tokio 0.2 timers.
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.

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.

that the behaviour of get_manifest_from_bonsai() and FilenodesOnlyPublic is

particular, get_manifest_from_bonsai() at the moment doesn't generate filenodes

Summary:
In the initial iteration of eden_apfs_mount_helper I parsed the human
readable version of the `diskutil apfs list` output to get all of the useful
information from it. Later, I switched to using `diskutil apfs list -plist`
because it simplified the parsing dramatically.
However, it was overlooked that the `mount_point` field was not present in
the plist output. That was usually fine, except in the one case that I
didn't test after changing the parser: after reboot macOS picks a volume
name to remount these volumes. The lack of the mount_point field meant
that we would simply skip the logic that deals with unmounting and remounting
the volume in the correct place.
In order to address this gap we now need to parse the mount table to determine
where the device is mounted, so that is what this diff does.

Summary:
This is done on a sort of best effort basis; the problem
we're aiming to solve (or at least avoid in the majority of cases)
is in these scenarios:
* `buck clean` gives up cleaning as soon as it finds a directory that
it doesn't have permissions to remove.
* `yarn` tries to look for node modules inside the `.Trashes` dir,
which it doesn't have permissions to access
macOS doesn't give us a solid way to indicate that these things should
be disabled at the time that we mount the volume; the various docs
and suggestions online all involve creating marker files to block the
system processes from performing their usual actions, and we could
set those up here, but if we create them with root permissions we'll
trigger the bad behavior in buck and yarn. If we create them with
regular user permissions then eg: running buck clean would remove them
and allow the system to recreate them.
The system will recreate the `.Trashes` directory when the user sends
something to the trash via Finder. Similarly, macOS will recreate
the fsevents directories when an application establishes a watch
on the volume using fsevents.
So we can't permanently prevent this problem, but by deleting these
things at mount time we should at least avoid it bubbling up for
the majority of users, and if those things come back and get in the
way, running `eden redirect unmount ; eden redirect fixup` should
remount and re-remove the problematic things.

* It doesn't trigger for thrift-originated downloads (eg: prefetch), only for
VFS operations through FUSE.
* Ideally we'd know exactly when we have a network related error in the store
code and use that to trigger the notification. However, we have a rather
convoluted set of importers and fallbacks today, one of which is interpreting
a generic response returned from a pipe, so it is not especially clear

Summary: Make the EdenAPI server report that it is exiting when asked to shut down. This ensures that Proxygen will stop sending traffic to servers that are about to be shut down by Tupperware. This diff is basically the same as krallin's diff D17626009 for the LFS server.

Summary: This diff sets up the Mononoke API (from the `mononoke_api` crate) in the EdenAPI server, and makes it available to route handlers by adding it to a new `EdenApiContext` struct that is maintained as part of the server's global state. The server's route handlers should use the Mononoke API for accessing source control data, and any new source control business logic should be incorporated into that crate rather than being part of the EdenAPI server itself.

Summary:
This crate provides the core features of the commonly known `Bytes` crate:
zero-copy slicing and cloning, while also supports mmap-backed buffers.
The main motivation is to replace `Mmap` in `indexedlog`. That has multiple
benefits:
- Handles 0-sized mmap more cleanly.
- Handles clones more cleanly.
- Gain the flexibility to zero-copy data without lifetime / reference.
- Gain the flexibility to switch to non-mmap data.
The `bytes::Bytes` crate does not yet support mmap buffers as of its latest
release (0.5.4).
Implementation wise, `minibytes::Bytes` uses `Option<Arc<dyn Trait>>` for the
"trait object". This makes implementing the mmap storage just one line.
`bytes 0.5.4` re-invents the "trait object" manually using unsafe code. It requires
about 50 lines to implement the mmap storage (in D19756122).

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.

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

Summary:
This is the api that will be used by Sandcastle to remap a commit from one repo

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.

crates needing to be individually fetched, subsequent builds will be faster.
