As discussed at [1], ui._runpager will be the new low-level API accepting a
pager command to actually run the pager. And ui.pager is the high-level API
which reads config directly from self.
This change is necessary for chgserver to override _runpager cleanly.

This revset returns the history of a range of lines (fromline, toline) of a
file starting from `rev` or the current working directory.
Added tests in test-annotate.t which already contains a reasonably complex
repository.
This yields ancestors of `fctx` by only keeping changesets touching the file
within specified linerange = (fromline, toline).
Matching revisions are found by inspecting the result of `mdiff.allblocks()`,
filtered by `mdiff.blocksinrange()`, to find out if there are blocks of type
"!" within specified line range.
If, at some iteration, an ancestor with an empty line range is encountered,
the algorithm stops as it means that the considered block of lines actually
has been introduced in the revision of this iteration. Otherwise, we finally
yield the initial revision of the file as the block originates from it.
When a merge changeset is encountered during ancestors lookup, we consider
there's a diff in the current line range as long as there is a diff between
the merge changeset and at least one of its parents (in the current line
range).
The function filters diff blocks as generated by mdiff.allblock function based
on whether they are contained in a given line range based on the "b-side" of
blocks.
Re-use the cmdutil._changesetlabels function introduced in c400c86d547f to
have consistent labels between the "changeset: " line in log command and the
"parent: " line in summary.
The "troubles" template keyword returns a list of evolution troubles.
It is EXPERIMENTAL, as anything else related to changeset evolution.
Test it in test-obsolete.t which has troubled changesets.
Every other template has the "raw" link load "raw-file." However,
fileannotate.tmpl's "raw" link loads "raw-annotate." This feels
inconsistent and wrong.
As far as I can tell, linking to the "raw annotate" view has occurred
since 2006.
repair.strip() expects a set of root revisions to strip. It then
builds the full set of descedants by walking the descandants of
each. It is rare that more than a few roots get passed in, but if that
happens, it will wastefully walk the changelog for each root. So let's
just walk it once.
I noticed this because the narrowhg extension was passing not only
roots, but all the commits to strip. When there were tens of thousands
of commits to strip, this resulted in quadratic behavior with that
extension.
Ubuntu 15.10 (Wily Werewolf) came out on October 22, 2015 and reached end of
life on July 28, 2016 [1]. Users were encouraged to upgrade to 16.04 (Xenial).
PPA doesn't allow new uploads targeting 15.10 anymore.

Similar to git, we add a special string:
HG: ------------------------ >8 ------------------------
that means anything below it is ignored in a commit message.
This is helpful for integrating with third-party tools that display the
The bootstrapping issue was addressed at the parsing phase and we expect
that fullreposet.__and__() fully complies to the smartset API, in which
'self & other' should return a result set in self's order. See also

Let's resurrect the docstring since our help module can detect the EXPERIMENTAL
tag and display it only if -v is specified.
This patch updates the test added by bbdfa2d5aaa2 since wdir() is now
documented.
Unlike p1 = null, p2 = null denotes the revision has only one parent, which
shouldn't be considered a child of the null revision. This was spotted while
fixing the issue4682 and rediscovered as issue5439.
The next release from upstream adds another named argument to this
function. Specify arguments by name so there is no ambiguity about
which argument is being passed.
select() is a notable example of syscalls which may fail with EINTR. If we
had a SIGWINCH handler installed, ssh would crash when the terminal window
was resized. This patch fixes the problem.
This is the behavior of the default __import__() function, which doesn't
validate the existence of the fromlist items. Later on, the missing attribute
is detected while processing the import statement.

The comtypes library relies on this (maybe) undocumented behavior, and we
got a bug report to TortoiseHg, sigh.
https://bitbucket.org/tortoisehg/thg/issues/4647/
The test added at 0be19b069edf verifies the behavior of the import statement,
so this patch only adds the test of __import__() function and works around
CPython/PyPy difference.
According to POSIX specification, just having group write access to a
file causes EPERM at invocation of os.utime() with an explicit time
information (e.g. working on the repository shared by group access
permission).
To ignore EPERM at closing file object in such case, this patch makes
checkambigatclosing._checkambig() use filestat.avoidambig() introduced
by previous patch.
Some functions below imply this code path at truncation of an existing
(= might be owned by another user) file.
- strip() in repair.py, introduced by 4d0a08431b6f
- _playback() in transaction.py, introduced by 48fe04792102
This is a variant of issue5418.
According to POSIX specification, just having group write access to a
file causes EPERM at invocation of os.utime() with an explicit time
information (e.g. working on the repository shared by group access
permission).
To ignore EPERM at renaming in such case, this patch makes
vfs.rename() use filestat.avoidambig() introduced by previous patch.
Now, advancing stat.st_mtime by os.utime() is used to avoid file stat
ambiguity. But according to POSIX specification, utime(2) with an
explicit time information is permitted only for a process with:
- the effective user ID equal to the user ID of the file, or
- appropriate privileges
http://pubs.opengroup.org/onlinepubs/9699919799/functions/utime.html
Therefore, just having group write access to a file causes EPERM at
applying os.utime() on it (e.g. working on the repository shared by
group access permission).
This patch adds class filestat utility function avoidamgig() to avoid
file stat ambiguity but skip it if EPERM.
It is reasonable to always ignore EPERM, because utime(2) causes EPERM
only in the case described above (EACCES is used only for utime(2)
with NULL).
43e3fb1c484e introduced a call to fctx.parents() for each line in
annotate output. This function call isn't cheap, as it requires
linkrev adjustment.
Since multiple lines in annotate output tend to belong to the same
file revision, a cache of fctx.parents() lookups for each input
should be effective in the common case. So we implement one.
Since the cache has to precompute parents so an aborted generator
doesn't leave an incomplete cache, we could just return a list.
However, we preserve the generator for backwards compatibility.
The effect of this change when requesting /annotate/96ca0ecdcfa/
browser/locales/en-US/chrome/browser/downloads/downloads.dtd on
the mozilla-aurora repo is significant:
p1(43e3fb1c484e) 5.5s
43e3fb1c484e: 66.3s
this patch: 10.8s
We're still slower than before. But only by ~2x instead of ~12x.
On the tip revisions of layout/base/nsCSSFrameConstructor.cpp file in
the mozilla-unified repo, time went from 12.5s to 14.5s and back to
12.5s. I'm not sure why the mozilla-aurora repo is so slow.
Looking at the code of basefilectx.parents(), there is room for
further improvements. Notably, we still perform redundant calls to
filelog.renamed() and basefilectx._parentfilectx(). And
basefilectx.annotate() also makes similar calls, so there is potential
for object reuse. However, introducing caches here are not appropriate
for the stable branch.
Currently the warning is ambiguous about whether the new tag (possibly specified
via --rev) is being added on a branch head or whether the working directory is
based on a branch head. Clarify the error message to eliminate this ambiguity.
Now, all URL in Mercurial source tree should refer mercurial-scm.org
domain instead of selenic.com.
*.po files are ignored in this patch, because they might contain
msgid/msgstr coming from old source files.
This ignorance seems safe enough, because such msgstr should be
ignored at runtime, because:
- msgid corresponded to it should be invalid, or
- msgstr itself should be marked as fuzzy at synchronized to recent hg.pot
If any additional examination for *.po files is needed in the future,
let i18n/check-translation.py achieve such examination.
BTW, some binary files (e.g. *.png) are meaningless for checking
reference to old domain in this patch, but aren't ignored like as *.po
files, because excluding multiple suffixes is difficult for regexp
matching.
Before this patch, check-code.py applies filtering on the file
content, to which filtering of previous check is already applied.
This might hide issues, which should be detected by a subsequent check
in "checks" list.
Fortunately, this problem hasn't appeared, because there is no
overlapping of filename matching (examined in the order below).
1. *.py or *.cgi
2. test-* (not *.t suffix)
3. *.c or *.h
4. *.t
5. *.txt
6. *.tmpl
For example, adding a test, which wants to examine raw comment text in
*.py files, at the end of current "checks" list doesn't work as
expected, because a filter for *.py files normalizes comment text in
them.
Putting such test at the beginning of "checks" list also resolves this
problem, but such dependence on the order decreases maintainability of
check-code.py itself.
This patch discards filtering result of previous check at the
beginning of each checks, for independence of each checks.
Some errors could in some cases show unfortunate scary and confusing warnings
from the httppeer delstructors:

To mute that, take 8bdb0bb8e209 to the next level and use getattr in __del__.
