The goal of this series is to have templates capable of displaying the
evolution of a changeset in a clean and human-readable way.
Add the succsandmarkers template return successors and markers so it can be
used separately like this:
> {succsandmarkers % "{get(succsandmarkers, "markers")|json};"}
The following patches will add template functions that takes successors and
markers as inputs and compute various obsfate fields from them.
We now also store markers in _succs. It will be useful for the obsfate template that
will use them to display more meaningful information like the list of users
that have evolved a changeset into its successors.
Mimic the standard API for copying in the _succs class, it makes the code
slightly cleaner and will be needed later for copying markers at the same time
than copying the list content.
It will be useful later when we will be adding markers to _succs in order to
represent a successorset with the list of markers from the root to each
successors sets. This information will be needed for the obsfate template I will
introduce.
Makes it a subclass of list so all callers will continue to work.
This is the last place we used the filepath arguments without first using the
context version.

`simplemerge()` will soon require context-like objects to work. Create a simple
context-like object that wraps the requested files and can be passed to the new
API.

This will be used as an abstraction by simplemerge to get the data it used to
read off the filesystem.

This moves the bundle2 part handling for bundlerepo out to a separate function
so extensions can participate in bundlerepo setup when using bundle2 bundles.

Previously, iterparts would yield the part to users, then consume the part. This
changed the part after the user was given it and left it at the end, both of
which seem unexpected. Let's seek back to the beginning after we've consumed
it. I tried not seeking to the end at all, but that seems important for the
overall bundle2 consumption.
This is used in a future patch to let us move the bundlerepo
bundle2-changegroup-part to be handled entirely within the for loop, instead of
having to do a seek back to 0 after the entire loop finishes.

A future patch will refactor certain parts of bundlerepo initiatlization such
that we need to create temp bundles from another function. Let's move this to
another function to support that.

The Mercurial core server doesn't yet include phase-heads parts in the
bundle, but our Google-internal server wants to do
that. Unfortunately, the usual exchange still happens even if
phase-heads part is included (including the short-circuited one for
old/publishing servers). That means that even if our server (again,
the Google-internal one, but also future Mercurial core servers)
includes a phase-heads part to indicate that some heads should be
drafts, that would still get overwritten by the phase updating that
happens after. So let's fix that by marking the phase step done if we
receive at least one phase-heads part in the bundle.

Setting `repo._shellvars` works but is not a clean way to pass the pushvars
information from the push command to the exchange operation. Therefore
change it to actually pass `pushvars` as a push operation argument instead.
This makes third party extension like remotenames easier to support pushvars
cleanly. The key value parsing and verification code has been moved to a
lower level so it's harder to be bypassed and easier to be used in
remotenames which could replace `push` command entirely.

There are cases like bisect when the conflict message can be None. So we make
sure that we don't print None in that case.
Thanks to Martin for catching this.

While using releasenotes extension, we will be using admonitions in commit messages.
The check (-c) flag will look for an admonition within the message. If it exists, it will
verify if it is stated under default or custom admonition. The check fails if the
admonition is not present in any of them. It also suggests similar admonitions
in case the admonition is invalid.

I didn't do anything to ensure correctness here, just enough to avoid
tracebacks in the import checker, which uses the native ast module to
try and parse all our Python files.
chg currently triggers `reposetup` as a side effect of `hg serve` command.
Therefore change the test to not output during `reposetup` to be compatible
with chg.

This enables the optimization introduced by b8d938230143 for non-rebase cases.
Before, the match couldn't be narrowed if it was e.g. alwaysmatcher.
The logic is copied from fca0d99edf8e.
As Augie reported in the bug, the current heuristic of choosing the
best tag of a merge commit by taking the one with newest tag (in terms
of tagging date) currently fails in the Mercurial repo itself. Copying
the example from Yuya:
$ hg glog -T '{node|short} {latesttag}+{latesttagdistance}\n' \
-r '4.2.3: & (merge() + parents(merge()) + tag())'
o cc59efae4cc0 4.2.3+5
|\
| o 06f60e88fc3a 4.2.3+4
| |\
| | o c191a9eb0b10 4.3-rc+109

| | ~
o | 49ada93fdc10 4.3.1+2

o 6a83ad94c0f2 4.2.3+3
|\
| ~
o 8e9dcdd1de74 4.2.3+2
:
o 525f2b18248f 4.2.3+0
|
~
It seems to me like the best choice is the tag with the smallest
number of changes since it (across all paths, not the longest single
path). So that's what this patch does, even though it's
costly. Best-of-5 timings for Yuya's command above shows a slowdown
from 1.293s to 1.610s. We can optimize it later.

The tests are much easier to read if one does not have to re-read the
setup part all the time to understand the graph shape.

45345e9870c3 and b30126fa95bc refactored ui methods to no longer
silently swallow some IOError instances. This is arguably the
correct thing to do. However, it had the unfortunate side-effect
of causing StdioError to bubble up to sensitive code like
transaction aborts, leading to an uncaught exceptions and failures
to e.g. roll back a transaction. This could occur when a remote
HTTP or SSH client connection dropped. The new behavior is
resulting in semi-frequent "abandonded transaction" errors on
multiple high-volume repositories at Mozilla.
This commit effectively reverts 45345e9870c3 and b30126fa95bc to
restore the old behavior.
I agree with the principle that I/O errors shouldn't be ignored.
That makes this change... unfortunate. However, our hands are tied
for what to do on stable. I think the proper solution is for the
ui's behavior to be configurable (possibly via a context manager).
During critical sections like transaction rollback and abort, it
should be possible to suppress errors. But this feature would not
be appropriate on stable.
