localrepo: prevent executable-bit only changes from being lost on amend
If you have just executable-bit change and amend it twice it will vanish:
* After the first amend the commit will have the proper executable bit set
in manifest but it won't have the the file on the list of files in
changelog.
* The second amend will read the wrong list of files from changelog and it
will copy the manifest entry from parent for this file.
* Voila! The change is lost.
This change repairs the bug in localrepo causing this and adds a test for it.
tests: escape bytes setting MSB in input of grep for portability
GNU grep (2.21-2 or later) assumes that input is encoded in LC_CTYPE,
and input is binary if it contains byte sequence not valid for that
encoding.
For example, if locale is configured as C, a byte setting most
significant bit (MSB) makes such GNU grep show "Binary file <FILENAME>
matches" message instead of matched lines unintentionally.
This behavior is recognized as a bug, and fixed in GNU grep 2.25-1 or
later. But some distributions are shipped with such buggy version
(e.g. Ubuntu xenial, which is used by launchpad buildbot).

This causes failure of test-commit-interactive.t, which applies grep
on CP932 byte sequence since
1111e84de635.
But, explicit setting LC_CTYPE for CP932 might cause another problem,
because it can't be assumed that all environment running Mercurial
tests allows arbitrary locale setting.
To resolve this issue, this patch escapes bytes setting MSB in input
of grep.
For this purpose:
- str.encode('string-escape') isn't useful, because it escapes also
control code (less than 0x20), and makes EOL handling complicated
- "f --hexdump" isn't useful, because it isn't line-oriented
- "sed -n" seems reasonable, but "sed" itself sometimes causes
portability issue, too (e.g.
900767dfa80d or
afb86ee925bf)
This patch is posted with "stable" flag, because
1111e84de635 is on
stable branch.
tests: test-archive.t use absolute_import
This is a step to adding a mercurial dependency to simplify py3 compat
hg: limit HGUNICODEPEDANTRY to py2
reload is not available in py3, and py3 is fatal anyway
hgcia: remove hgcia (BC)
As discussed at:
https://www.mercurial-scm.org/pipermail/mercurial-devel/2016-March/081018.html,
cia service is down for years. It also uses socket.setdefaulttimeout() which
will break chg. This patch removes the extension.
