test-check-code: do not use xargs We have too many files, and passing them via arguments could cause strange errors on some platforms [1]. Since check-code.py can now take "-" and read file names from stdin, use it instead of xargs to avoid the argv size limit. [1]: https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-April/096346.html

check-code: use "-" to specify a list of files from stdin This will be used by the next patch.

perf: add historical portability for util.timer util.timer has been introduced in ae5d60bb and used in perf.py since 22fbca1d. For historical portability, forcibly define util.timer in perf.py

diff: add --binary option for git mode diffs This patch adds --binary option to `hg diff` and `hg export` to allow more control about when binary diffs are displayed in Git mode as well as some tests to verify it behaves correctly (issue5510).

patch: make diff in git mode respect --text option (issue5510) This changeset makes patch respect -a/--text option in --git mode by aligning its behaviour with git itself.

py3: have registrar process docstrings in bytes Mixing bytes and unicode creates a mess. Do things in bytes as possible. New sysbytes() helper only takes care of ASCII characters, but avoids raising nasty unicode exception. This is the same design principle as sysstr().

localrepo: fix deprecation version for 'repo._link' The patch lingered for a while and nobody noticed when it was resubmitted.

localrepo: fix deprecation version for 'repo.join' The patch lingered for a while and nobody noticed when it was resubmitted.

tests: make zstd-related output optional Caught by the buildbot with --pure, fix suggested by indygreg.

check-code: update test IP address enforcement checks Instead of mentioning 127.0.0.1, we should use $LOCALIP. Anytime $LOCALIP appears in output, we should make sure we use (glob) on that line of output so that weird environments that do remapping jiggery pokery (such as our FreeBSD buildbot that's in a jail) don't get spurious test failures.
