Summary:
Previously, NameDag only supports writing directly to disk. That is not easy
for hg to use, since hg knows commits before bookmark names during pull, while
the API requires both commits and bookmarks (to decide which commits belong to
the "master" group) at the same time.
The old API also does not match other storage layers like indexedlog and
metalog, where writes are buffered until explicitly flushed.
This diff adds the "write-in-memory" (named "add_heads"), and "flush" APIs to
make NameDag easier to use. Under the hood, it just copies the "added" portion
of the DAG, and re-use the old API ("build", renamed to "add_heads_and_flush")
to do the job.
Note: The buffered changes pattern cannot be used in IdDag, since Ids might
have to be re-assigned on flush. But NameDag does not expose the raw Ids in its
"normal" interface, so it's fine to reassign Ids on flush.

Summary:
Previously the localrepo object contained a list of handlers to invoke
after status finished executing. This was used for 1) updating the fsmonitor
state with the new clock, ignore hash, and list of notable files, and 2)
updating the list of ignored files in treestate.
As part of moving all fsmonitor subtlities behind the filesystem abstraction,
this diff moves the fsmonitorstate file updating to be in the filesystem layer.
This also moves it inside the same transaction as the lookup file cleanup, which
removes the need for the hacky self._newid logic to detect if the dirstate was
changed by an external process.
(self._newid was previously added so that our second dirstate transaction, which
updates the fsmonitorstate, could determine if the dirstate had either been
changed by this process earlier in the lookup cleanup transaction, or if it had
been changed by an external process).

Summary:
Previously, between 100 to 500 runs, the test is likely to fail:
---- log::tests::test_repair_and_delete_content stdout ----
thread 'log::tests::test_repair_and_delete_content' panicked at 'assertion failed: `(left == right)`
left: `"Verified first 141 entries, 999 of 1400012 bytes in log\nReset log size to 999\nIndex \"c\" is incompatible with (truncated) log\nRebuilt index \"c\""`,
right: `"Rebuilt metadata\nVerified first 141 entries, 999 of 1400012 bytes in log\nReset log size to 999\nRebuilt index \"c\""`', src/log.rs:3414:9
The "Rebuilt metadata" part is missing.
This is because after D17742003, the end of `meta` is the `epoch`, which is a
random number. The test is rewriting the end of `meta` to corrupt it. That
has a chance to not corrupt the file. Change the test to corrupt the fixed
header of meta so it can always corrupt the file and therefore stabilize
the test.

Summary:
Per discussion, we decided to use "VertexName" as the struct name for things
like commit hashes, or the string names in tests (or the Mozilla DAG in tests).
Therefore, introduce a dedicated VertexName type and repalce all callsites to
use it.
`bytes::Bytes` is used so copying the `VertexName` is somewhat considered cheap.
This adds some overhead copying slices (and `Bytes` has some overhead). It
regresses the "building segments" benchmark from 673ms to 773ms, which seems
okay given the cleaner interface.

Summary:
A new implementation for rendering DAGs.
This new crate implements a generic DAG renderer, that can convert a
topologically sorted sequence of DAG nodes into a sequence of strings suitable
for rendering to a terminal.
The new renderer differs from the old renderer in a few important ways:
* It prioritizes keeping commits linear, and will allow gaps to form if
that will allow the history of the commits to be kept in a straight
line. This makes it easier to track long parallel histories.
* It supports octopus merges (nodes with more than two parents). Even
though Mercurial doesn't support octopus merge commits, summary DAGs
with omitted nodes can still end up with logical octopus merges.
* It supports reservation of columns for specific nodes. This can be
used to support smartlog-style indentation of draft stacks without
needing to hack around it by creating fake nodes.
* It separates out forming the graph from generating the lines. This
allows multiple back-ends for generating different styles of graph.
There are three back-ends implemented:
`AsciiRenderer` renders similar to the old graph renderer, using ASCII
characters. For example:
```
o F
|
| o E
| |
| | o D
.-----'
o | | C
+---'
o | B
:/
o A
```
`AsciiLargeRenderer` uses larger ASCII blocks to give a clearer picture of
complex graphs. For example:
```
o F
|
|
| o E
| |
| |
| | o D
______/
/ | |
o | | C
| ___/
|/ |
o | B
: /
:/
o A
```
`BoxDrawingRenderer` uses Unicode box drawing characters to give a more
continuous rendering of the graph, however requires support for these
characters in the terminal font. For example:
```
o F
│
│ o E
│ │
│ │ o D
╭─────╯
o │ │ C
├───╯
o │ B
├─╯
o A
│

The `map_pyerr<PE>` API is kind of hard to use correctly since the
code that calls `map_pyerr` does not really know the best suitable error type.
The existing code also "encourage"s the use of stdlib error types like
RuntimeError, ValueError, etc since the code is shorter, which is not great.
Error types from `mercurial.error` are better choices.
With previous diffs in this stack, we now decide the Python error type based
on the Rust error type. It's no longer necessary to specify an error type
with `map_pyerr<PE>`. So let's just drop the type parameter.
A `RustError` was added for error types that `cpython-ext` does not know how
to convert. We should avoid leaking it to the Python land by just implementing
how to convert `anyhow::Error` to `PyErr` in `cpython-ext`.

Summary:
I encountered a 19s `hg sl` run where 13s were spent on
`remotenames.updateaccessedbookmarks` (8 times).
{F225347899}
The filesystem is unusually slow since the it's nearly full. However, the
updates are not really necessary since I'm not accessing more remote names.
Accessing one bookmark via smartlog rewrites the entire accessed file, which is
O(N^2) and undesirable.
Improve it by skipping writing if nothing has changed. In the future we might
want to optimize it further by:
- Only update (and do ui.log) "accessedbookmarks" at most once per command.
- Potentially drop the "accessedbookmarks" tracking by using "remotenames"
directly - everything in "remotenames" is accessed.

Summary:
Currently, hg's lfs extension used bytes concatenation to download a response
from the server-side. However, concatenating bytes in Python can be
inefficient, since it'll re-allocate the whole thing and copy it every time you
concatenate.
This makes repeated concatenation O(N^2) on the number of things you
concatenate, which is undesirable. This diff updates hg's lfs extension to not
do that.

Summary:
HTTP makes no provision to tell your client that you failed halfway through
producing your response and won't have the answer they're looking for. So, if a
LFS server fails while producing a response, then we'll report an OID mismatch.
We can do a little better and disambiguate between "the server sent us the
wrong blob" (very scary) and "the server crashed" (merely annoying) by looking
at the content length of the response we got back. If it's not what was
advertised, we can reasonably safely assume the server crashed.

Summary:
The test is flaky in recent OSX builds.
The test is about a chg feature. Right now we only use chg on Linux. So limit
the test to Linux only.

Summary:
After D19043330, the test is failing on Windows (no execbit).
When converting a repo, we almost always want to preserve the execbit. So let's
just skip the test if execbit is not available.

Summary:
Reduce the log level for a few messages to help reduce some less important
clutter when running with an elevated debug log level.

Summary:
Remove some half-baked, unnecessary logic for caching sizes separately
from SHA-1. Eden's backing stores do not support chunking large files
yet, so there's no value in caching content SHA-1 and size
separately. This fixes a scenario where fetching blob size and then
SHA-1 would result in two backing store imports.

Summary:
Troditionally, ObjectStore relied on HgBackingStore writing directly
to LocalStore in order to cache trees. This had the unfortunate side
effect that other backing store implementations did not benefit from
tree caching.
Move tree caching into ObjectStore so all backing stores benefit from
tree caching.

Summary:
If a GC ran at the same time as HgBackingStore imported a commit, the
import would fail. Rather than round-tripping the tree through the
LocalStore, just return it.

Summary: There is one instace of `getScmStatusBetweenRevisions` in use - it is used in the eden cli in a hacky way to check if a commit hash is valid. Since this is not used anywhere else in a meaningful way, this replaces that use case with a hg call and depreciates `getScmStatusBetweenRevisions`
