I'd like to call the function from an extension, passing both "strip"

caller seems to be mq.py, which doesn't even pass "strip".

Less duplication and it's also easier to add extra "tags" everywhere at once.
These aren't tags as defined `hg help glossary` (hence the quotes), they are
simply called that. They include branch name (in different styles if changeset
is a head of that branch or not), (actual) tags and bookmarks. Good candidates
to add to this list would be changeset phase and obsoletion status.
.. feature::
Let 'hg rebase' avoid content-divergence by skipping obsolete
changesets (and their descendants) when they are present in the rebase
set along with one of their successors but none of their successors is
in destination.
In the following example, when trying to rebase 3:: onto 2, the rebase
will abort with "this rebase will cause divergence from: 4":
o 7 f
|
| o 6 e
| |
| o 5 d'
| |
x | 4 d (rewritten as 5)
|/
o 3 c
|
| o 2 x
| |
o | 1 b
|/
o 0 a
By excluding obsolete changesets without a successor in destination (4
in the example above) and their descendants, we make rebase work in this
case, thus giving:
o 11 e
|
o 10 d'
|
o 9 c
|
o 8 b
|
| o 7 f
| |
| | x 6 e (rewritten using rebase as 11)
| | |
| | x 5 d' (rewritten using rebase as 10)
| | |
| x | 4 d
| |/
| x 3 c (rewritten using rebase as 9)
| |
o | 2 x
| |
| x 1 b (rewritten using rebase as 8)
|/
o 0 a
where branch 4:: is left behind while branch 5:: is rebased as expected.
The rationale is that users may not be interested in rebasing orphan
changesets when specifying a rebase set that include them but would
still want "stable" ones to be rebased. Currently, the user is suggested
to allow divergence (but probably does not want it) or they must specify
a rebase set excluding problematic changesets (which might be a bit
cumbersome). The approach proposed here corresponds to "Option 2" in
https://www.mercurial-scm.org/wiki/CEDRebase.
We extend _computeobsoletenotrebased() so that it also return a set of
obsolete changesets in rebase set without a successor in destination but
with at least one successor in rebase set. This
'obsoletewithoutsuccessorindestination' is then stored as an attribute
of rebaseruntime and used in _performrebasesubset() to:
* filter out descendants of these changesets from the revisions to
rebase;
* issue a message about these revisions being skipped.
This only occurs if 'evolution.allowdivergence' option is off and
'rebaseskipobsolete' is on.
It is a bit wonky to assign the same object to multiple
attributes and then possibly overwrite them later.
Refactor the code to use a local variable and defer attribute
assignment until the final values are ready.
This required passing the bundle instance to _handlebundle2part().
The only use of this method I could find is Facebook's
treemanifest extension. Since it is a private method, I don't
think it warrants an API callout.

For methods that are implemented, we change arguments to match

The keys of keyword arguments must be str on Python 3 which is unicode. This
patch make sure we pass keyword arguments with keys are str everywhere in this

Everything is pretty self-explanatory except the last hunk, where jshint
complains: "Misleading line break before '||'; readers may interpret this as an
expression boundary."
There is a tweakable called "laxbreak" that allows line breaks before
operators, but I think it's fine to simply join this one line and avoid extra
config for now (we can cook up and add a sensible .jshintrc later).
The internal representation of bookmark value is binary. The fact we stored
'hex' was an implementation detail from using pushkey.
We move the values in 'pullop.remotebookmarks' to binary before adding a way to
exchange bookmarks not based on pushkey.

The dirstate typically tries to keep the nonnormalset and otherparentset
up-to-date when making changes to the dirstate. In the case of files marked
normallookup, however, it erroneously removes the file from the nonnormalset,
after _addpath had just added it.
This doesn't seem to matter at the moment, as nothing relies on the
nonnormalset being correct at this point, however a future re-implementations
of the dirstate map will require this to be kept up-to-date correctly.

This is fixing quadratic behavior, which is probably not noticeable in the
common case, but if a very large directory gets added here, it can get pretty
bad. This was noticed because we had some pushes that spent >25s in changegroup
generation calling min() here, according to profiling.
The original reasoning for min() being used in 1d71430e1d28 was that, at that
point in the series, we were adding almost everything to tmfnodes during the
first iteration through the loop , so we needed to avoid sending child
directories before parents. Later changes made it so that the child directories
were added only when we visited the parent directory (not all of them on the
first iteration), so this is no longer necessary - there won't be any child
directories in tmfnodes before the parents have been sent.
This does mean that the manifests are now exchanged unordered, whereas
previously we would essentially do [a, b, b/c, b/c/d, e], we now can send a, b,
and e in any order; b/c must still follow b, and b/c/d must still follow b/c.

With our treemanifest logic, the manifests are no longer transported as part of
the changegroup and are no longer stored in a revlog. This means the
self.manifestlog line in bundlerepo.filestart no longer calls
_constructmanifest, and therefore does not consume the manifest portion of the
changegroup, which means filestart is not populated and we result in an infinite
loop.
The fix is to make filestart aware that self.manifestlog might not consume the
changegroup part, and consume it manually if necessary.
There's currently no way to test this in core, but our treemanifest extension
has tests to cover this.

Right now, successorsetverb only needs successors to compute the verb. But we
will want use additional information (effect-flags and operation) in the near
future to compute a better verb.
Add the markers parameter now so extensions (like Evolve) could wrap the
function and start experimenting around better obsfate verbs.
As successorsetverb now takes both successorset and markers parameters, rename
it to obsfateverb, successorsetandmarkersverb was too long.

Previously, the caller was responsible for creating the directory structure of
files written out using a path template. This is onerous, especially if the
exact filenames are not known upfront, but are being accessed via a matcher.
This patch changes things so that hg will attempt to create the appropriate
directories before writing the output file.
