Summary:
xavierd and I realized that memcache is not actually enabled in EdenFS as `ContentStoreBuilder` only sets it when there is are remote store. We believe turning on memcache store can help us improve some performance for importing blobs (80% hit rate).
This diff adds a noop remote store that does nothing to trick `ContentStoreBuilder` to include the memcache store. We decided to go this way instead of modifying `ContentStoreBuilder` is because EdenFS is going to have a real remotestore very soon, and changes to `ContentStoreBuilder` may have some impact on how Mercurial uses it.

Summary:
Part of the mutation graph (excluding split and fold) can fit in the DAG
abstraction. Add a method to do that. This allows cross-dag calculations
like:
changelogdag = ... # suppose available by segmented changelog
# mutdag and changelogdag are independent (might have different nodes),
# with full DAG operations on either of them.
mutdag = mutation.getdag(...)
mutdag.heads(mutdag.descendants([node])) & changelogdag.descendants([node2]) # now possible
Comparing to the current situation, this has some advantages:
- No need to couple the "visibility", "filtered node" logic to the mutation
layer. The unknown nodes can be filtered out naturally by a set "&"
operation.
- DAG operations like heads, roots can be performed on mutdag when it's
previously impossible. We also get operations like visualization for free.
There are some limitations, though:
- The DAG cannot represent non 1:1 modifications (fold, split) losslessly.
Those relationships are simply ignored for now.
- The MemNameDag is not lazy. Reading a long chain of amends might be slow.
For most normal use-cases it is probably okay. If it becomes an issue we
can seek for other solutions, for example, store part of mutationstore
directly in a DAG format on disk, or have fast paths to bypass long
predecessor chain calculation.

MutableDataPack::get_delta_chain must remain in some form, as it necessary to implement get using a sequence of Deltas. It has been moved to a private inherent impl.
DataPack::get_delta_chain must remain in some form for the same reasons, and in fact both implenetations can probably be merged, but it is also used in repack.rs for the free function repack_datapack. There are a few ways to address this without making DataPack::get_delta_chain part of the public API. I've currently chosen to make the method pub(crate), ie visible only within the revisionstore crate. Alternatively, we could move the repack_datapack function to a method on DataPack, or use a trait in a private module, or some other technique to restrict visibility to only where necessary.
UnionDataStore::get has been modified to call get on it's sub-stores and return the first which matches the given key.

Summary:
While the change looks fairly mechanical and simple, the why is a bit tricky.
If we follow the calls of `ContentStore::get`, we can see that it first goes
through every on-disk stores, and then switches to the remote ones, thanks to
that, when we reach the remote stores there is no reason to believe that the
local store attached to them contains the data we're fetching. Thus the
code used to always prefetch the data, before reading from the store what was
just written.
While this is true for regular stores (packstore, indexedlog, etc), it starts
to break down for the LFS store. The reason being that the LFS store is
internally represented as 2 halves: a pointer store, and a blob store. It is
entirely possible that the LFS store contains a pointer, but not the actual
blob. In that case, the `get` executed on the LFS store will simply return
`Ok(None)` as the blob just isn't present, which will cause us to fallback to
the remote stores. Since we do have the pointer locally, we shouldn't try to
refetch it from the remote store, and thus why a `get_missing` needs to be run
before fetching from the remote store.
As I was writing this, I realized that all of this subtle behavior is basically
the same between all the stores, but unfortunately, doing a:
impl<T: RemoteDataStore + ?Sized> HgIdDataStore for T
Conflicts with the one for `Deref<Target=HgIdDataStore>`. Macros could be used
to avoid code duplication, but for now let's not stray into them.

Summary:
When creates directories sometime we want to make sure other users within the same group have the write access to it to enable data sharing. Previously we rely on setting umask for the entire process to make sure the newly created directories have the correct permission bit. This is kind fragile and error-prone when running in a multi-thread environment.
This diff introduces an internal function `create_dir_with_mode` to create directory with specified permission mode. It first creates a temporary directory within the parent of the directory being created, setting up the correct permission bit, then attempts to rename the temporary directory to the desired name. This ensures that we never leave a directory without the correct permission in the place we need and without changing umask for the process.

Summary:
On repack, when the Rust stores are in use, the repack code relies on
ContentStore::commit_pending to return the path of a newly created packfile, so
it won't delete it when going over the repacked ones. When LFS is enabled, both
the shared and the local stores are behind the LfsMultiplexer store that
unfortunately would always return `Ok(None)`. In this situation, the repack
code would delete all the repacked packfiles, which usually is the expected
behvior, unless only one packfile is being repacked, in which case the repack
code effectively re-creates the same packfile, and is then subsequently
deleted.
The solution is for the multiplex stores to properly return a path if one was
returned from the underlying stores.

Summary:
The part of status that lists what files have changed is called
PendingChanges. This diff introduces the initial stub for PendingChanges. The
pending changes algorithm involves three parts:
1. Looking at files on the filesystem for changes.
2. Looking at files in the dirstate map for changes.
3. Looking at the content for any files that we were unsure of during steps 1
and 2.
This diff puts the basic state machine in place, and accepts the basic
information about the working copy (the root and what type of filesystem it is).
In the future we might have it detect what type of filesystem it is, but for now
this makes it easy.

Summary:
treestate.get_filtered_keys passes directory paths to the filter
function and returns directory matches with a trailing '/' on the end. This
makes it difficult to act as a path normalization function when the caller
doesn't know if the path is a file or directory.
It seems like we can just strip the trailing '/' before exposing the strings to
the caller (both as filter inputs and as get_filtered_keys outputs).
This is useful in the following diff that adds a case normalization crate.

Summary:
The Memcache store is voluntarily added to the ContentStore read store, first
as a regular store, and then as a remote one. The regular store is added to
enable the slower remote store to write to it so that blobs are uploaded to
Memcache as we read them from the network. The subtle part of this is that the
HgIdDataStore methods should not do anything, or the data fetched won't be
written to any on-disk store, forcing a refetch next time the blob is needed.

Summary:
When comparing empty file with file with content our xdiff wrongly included
warning about missing newline, which also made the line counter in the hunk
header off-by-one.
Empty files are quite rare in our repos, that's why I discovered this bug only
now (it broke phabricator parsing of this single commit).

Summary:
Ideally, either the ContentStore, or the upper layer should verify that we
haven't missed uploading a blob, which could lead to weird behavior down the
line. For now, all the stores will return the keys of the blobs that weren't
uploaded, which allows us to return these keys to Python.

Summary:
We want Mercurial to become more responsible for it's own
configuration, instead of relying on chef and other means. To do so, let's
introduce a new `hg debugdynamicconfig` that can generate dynamic configs for
a given repository based on various states, like what tier it's in or what shard
that machine is in. By default it generates to '.hg/hgrc.dynamic' for the given
repository.
Currently it just sets the hostgroup config.
Future diffs will make Mercurial consume this config, and possibly have Mercurial
call this command asynchronously when it notices the file is out-of-date.

Summary: Since the old Edenfs warning is usually for simply picking up new eden releases, we can suggest the user runs a graceful restart instead of a normal restart to avoid them running into `Transport not connected` errors. This path is only hit in unix environments, so windows users will not see this (since graceful restart isn't supported there yet). Since this is a manual step as well, it will be easier for a user to see if they run into an issue here. This can also enable us to get more telemetry from users running graceful restarts.

Summary:
Sometimes the Rust io::Error is generated without an errno (ex. pipe
0.2 would generate BrokenPipe error without an errno). The Python
land uses errno to check error type (Python does not have io::ErrorKind).
Therefore attempt to translate ErrorKind to Python errno. Without this
exiting the rust pager early would crash like:
StdioError: [Errno None] pipe reader has been dropped
abort: pipe reader has been dropped

Summary:
On upload, read all the local blobs and upload them to the LFS server. This is
necessary to support `hg push` or `hg cloud sync` for local LFS blobs.
One of the change made here is to switch from having the batch method return an
Iterator to having them take a callback. This made it easier to write the gut
of the batch implementation in a more generic way.
A future change will also take care of moving local blobs to the shared store
after upload.

This diff turns off the support_old_nightly feature of async-trait (https://github.com/dtolnay/async-trait/blob/0.1.24/Cargo.toml#L28-L32) everywhere in fbcode. I am getting ready to remove the feature upstream. It was an alternative implementation of async-trait that produces worse error messages but supports some older toolchains dating back to before stabilization of async/await that the default implementation does not support.
This diff includes updating async-trait from 0.1.24 to 0.1.29 to pull in fixes for some patterns that used to work in the support_old_nightly implementation but not the default implementation.

Mononoke has to be rolled out, the Mononoke LFS server will be unable to serve
blobs, but some clients may still have LFS pointers locally but not the
corresponding blob. For this, we need to be able to fallback to fetching the
blob via the getpackv2 protocol.
