test-flagprocessor: use changegroup3 in bundle2 This will force "hg bundle" to use changegroup3 in the test. It is important since only changegroup3 preserves revlog flags.

bundle: allow bundle command to use changegroup3 in tests Since bundle2 writes changegroup version, we can just reuse the bundle2 format for changegroup3. This won't enable the bundle command to write changegroup3 in the wild, since exchange.parsebundlespec only returns changegroup2. It unlocks tests to override exchange.parsebundlespec and get "hg bundle" write changegroup3.

tests: add per-line output conditionals for Windows

run-tests: support per-line conditional output in tests Duplicating entire tests just because the output is different is both error prone and can make the tests harder to read. This harnesses the existing '(?)' infrastructure, both to improve readability, and because it seemed like the path of least resistance. The form is: $ test_cmd output (hghave-feature !) # required if hghave.has_feature(), else optional out2 (no-hghave-feature2 !) # req if not hghave.has_feature2(), else optional I originally extended the '(?)' syntax. For example, this: 2 r4/.hg/cache/checkisexec (execbit ?) pretty naturally reads as "checkisexec, if execbit". In some ways though, this inverts the meaning of '?'. For '(?)', the line is purely optional. In the example, it is mandatory iff execbit. Otherwise, it is carried forward as optional, to preserve the test output. I tried it the other way, (listing 'no-exec' in the example), but that is too confusing to read. Kostia suggested using '!', and that seems fine.

test-run-tests: pad the failure test to preserve the run order Test size seems to dictate the order in which the tests are run, and the next patch will add to test-success.t. Similar to c0cecc153d25.

run-tests: prevent a (glob) declaration from reordering (?) lines Previously, if a series of optional output lines marked with '(?)' had a (glob) in one of the first lines, the output would be reordered such that it came last if none of the lines were output. The (re) declaration wasn't affected, which was helpful in figuring this out. There were no tests for '(re) (?)' so add that to make sure everything plays nice.

py3: use pycompat.byteskwargs() to convert opts to bytes We have converted opts to unicodes before passing them.

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.

tests: fix missing (glob) annotations in test-push-http.t

tests: fix missing (glob) annotations in test-push-http-bundle1.t

tests: fix missing (glob) annotations in test-https.t

tests: fix missing (glob) annotations in test-bundle2-exchange.t

util: fix %-formatting on docstring by moving a closing parenthesis We have to do the % formatting over the sysstr, since the things we're going to splat into it are themselves sysstrs. This is probably technically wrong-ish, since bt is probably actually a bytestr here, but this fixes the immediate issue, which was that hg was broken on Python 3.

revset: stop supporting plain list as input set (API) There was no deprecwarn(), but this is the same kind of API compatibility as the one removed by the previous patch.

revset: stop supporting predicate that returns plain list (API) It's said to be removed after 3.9.
