test: extract develwarn transaction testing in its own command The lack of locking for a transation is about to change from a warning to an error. We first extract the test decidated to this warning to make the next changeset clearer.

graphmod: update edgemap in-place The edgemap update was not actually propagated to future asciiedge calls; update the edge state dictionary in-place instead.

tests: test-archive.t use mercurial.util for urllib compat

tests: test-archive.t use sys.stdout.buffer for binary output in py3

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). http://debbugs.gnu.org/cgi/bugreport.cgi?bug=19230 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=800670 http://packages.ubuntu.com/xenial/grep 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.
