util: correct check of sys.version_info sys.version is a string, and shouldn't be compared against a tuple for version comparisons. This was always true, so we were never disabling gc on 2.6. >>> (2, 7) >= '2.7' True >>> (2, 6) >= '2.7' True

py3: switch to .items() using transformer .iteritems() don't exist in Python 3 world. Used the transformer to replace .iteritems() to .items()

py3: handle multiple arguments in .encode() and .decode() There is a case and more can be present where these functions have multiple arguments. Our transformer used to handle the first argument, so added a loop to handle more arguments if present.

py3: convert to unicode to pass into encode() encoding.encoding is bytes, we need to pass it to encode() which accepts unicodes in py3, so used pycomapt.sysstr() Also this can't be done using transformer as that only transforms the string values not variables.

templater: use "needle" and "haystack" as (meta-)variables for ifcontains() It wasn't immediately clear if it's supposed to look for "search" in "thing" or "thing" in "search".

copies: mark checkcopies as internal with the _ prefix

copies: split u1/u2 to u1u/u2u and u1r/u2r These will be made different in case of grafts by another patch in this series.

copies: style fixes and add comment

copies: limit is an optimization, and doesn't provide guarantees

revset: do not rewrite ':y' to '0:y' (issue5385) That's no longer valid since the revision 0 may be hidden. Bypass validating the existence of '0' and filter it by spanset.

revset: extract function that creates range set from computed revisions So we can pass m=0 to _makerangeset() even if the revision 0 is hidden. Hidden revisions are filtered by spanset.

lazymanifest: write a more efficient, pypy friendly version of lazymanifest

hg: set default path correctly when doing a clone+share (issue5378) Before, if performing a clone+share from a repo that was itself using shared storage, the share code would copy paths.default from the underlying repo being shared, not from the source given by the user. This patch teaches hg.clonewithshare to resolve paths.default and pass it to share so it can be written to the hgrc accordingly.

annotate: calculate line count correctly Before this patch, the "lines" function inside "annotate" returns 1 for empty text (''). This patch makes it 0. Because the function should match mdiff.splitnewlines (used by mdiff.allblocks), or s.splitlines (used at the end of the "annotate" method). Both len(mdiff.splitnewlines('')) and len(''.splitlines(True)) are 0. This issue was discovered while testing fastannotate [1]. I could not find a test case to reveal this issue. However in theory this could reduce memory usage a little bit, and avoids surprises when people are touching this area in the future.

py3: use unicode in is_frozen() imp.is_frozen() doesnot accepts bytes on Python 3. It does accept both bytes and strings on Python 2.

py3: use unicodes in __slots__ __slots__ doesnot accepts bytes on Python 3.

merge with stable

url: fix crash by empty path with #fragments Before, "#foo" paths made hg crash. We've moved the #fragment parsing at 64fbd0de9773, but we shouldn't set path to None too early. This patch just removes the "if not path:" block since that's checked a few lines later.

py3: make i18n use encoding.environ

py3: provide encoding.environ which is a dict of bytes This can't be moved to pycompat.py since we need encoding.tolocal() to build bytes dict from unicode os.environ.

py3: convert encoding name and mode to str Otherwise tolocal() and fromlocal() wouldn't work on Python 3. Still tolocal() can't make a valid localstr object because localstr inherits str, but it can return some object without raising exceptions. Since Py3 bytes() behaves much like bytearray() than str() of Py2, we can't simply do s/str/bytes/g. I have no good idea to handle str/bytes divergence.

pycompat: extract function that converts attribute or encoding name to str This will be used to convert encoding.encoding to a str acceptable by Python 3 functions. The source encoding is changed to "latin-1" because encoding.encoding can have arbitrary bytes. Since valid names should consist of ASCII characters, we don't care about the mapping of non-ASCII characters so long as invalid names are distinct from valid names.

Added signature for changeset 149433e68974

pycompat: provide 'ispy3' constant We compare version_info at several places, which seems enough to define a constant.

Added tag 3.9.2 for changeset 149433e68974

extensions: add a note about debug output during extensions search These messages do not show up when one use '--debug'. This is quite confusing so we clarify the situation next to the 'ui.debug' call.

extensions: fix a debug message when searching for extensions The "next" value was wrong. When 'hgext.NAME' is not found we now search for 'hgext3rd.NAME'.

dirstate: rebuild should update dirstate properly Updating dirstate by simply adding and dropping files from self._map doesn't keep the other maps updated (think: _dirs, _copymap, _foldmap, _nonormalset) thus introducing cache inconsistency. This is also affecting the debugstate tests since now we don't even try to set correct mode and mtime for the files because they are marked dirty anyway and will be checked during next status call.

histedit: avoid converting nodeid to context and back again It looks like this became unnecessary in e767f5aba810 (histedit: fix preventing strips during histedit, 2015-04-04).

help: mark boolean flags with [no-] to explain that they can be negated That is, help gets tweaked thus: global options ([+] can be repeated): -v --[no-]verbose enable additional output Other proposals have included: global options ([+] can be repeated, options marked [?] are boolean flags): -v --verbose[?] enable additional output and global options ([+] can be repeated, options marked [^] are boolean flags): -v --verbose[^] enable additional output which avoid the unfortunate visual noise in this patch. In this version's favor, it's consistent with what I'm used to seeing in man pages and similar documentation venues.

mdiff: remove unused parameter 'refine' from allblocks()

demandimport: error out early on missing attribute of non package (issue5373) If the parent module isn't a package, all valid attributes must be obtained from it. We can raise ImportError early if any attributes not found.

demandimport: add 'nt' to ignore list (issue5373) pathlib2 tries to import nt. Since it is a built-in module, there should be no performance penalty. https://github.com/mcmtroffaes/pathlib2/blob/release/2.2.0/pathlib2.py#L33

demandimport: add '_ctypes.pointer' to ignore list on PyPy The pointer module is shadowed by a subsequent import. Our demand importer can't handle this because both sub modules and attributes live in the same namespace. https://bitbucket.org/pypy/pypy/src/release-5.0.1/lib_pypy/_ctypes/__init__.py#__init__.py-5

hgweb: make anchor name actually match its href on help index page

perf: add perfchangegroupchangelog command This command can be used for testing the performance of producing the changelog portion of a changegroup. We could use additional perf* commands for testing other parts of changegroup. Those can be written another time, when they are needed. (And those may want to refactor the changegroup generation API so code can be reused.) Speaking of code reuse, yes, this command does reinvent a small wheel. I didn't want to scope bloat to change the changegroup API because that will invite bikeshedding.

perf: add --reverse to perfrevlog It can be useful to know how fast we can read revisions from a revlog in reverse. This operation tends to occur in `hg log` commands, for example.

log: copy the way of ancestor traversal to --follow matcher (issue5376) We can't use fctx.linkrev() because follow() revset tries hard to simulate the traversal of changelog DAG, not filelog DAG. This patch fixes _makefollowlogfilematcher() to walk file ancestors in the same way as revset._follow(). I'll factor out a common function in future patches.

log: unroll loop that populates file paths for --patch --follow matcher We can't handle the first fctx in the same manner as its ancestors. Also, I think the original code was too tricky.

wireproto: rename argument to groupchunks() groupchunks() is a generic "turn a file object into a generator" function. It isn't limited to changegroups. Rename the argument and update the docstring to reflect this.

tests: actually test non-generaldelta variant for stream clones 608cabec1b15 accidentally made both tests test generaldelta repos. Restore the test for a non-gd repo.

revlog: document high frequency of code execution Recording my notes while working on performance optimization.

revlog: make code in builddelta() slightly easier to read self.compress() is destructured into its components. "l" is renamed to "deltalen."

py3: update test expectation on stable

grep: rewrite help to better document current (confusing) behavior

templates: add built-in files() function We already support multiple primitive for listing files, which were affected by the current changeset. This patch adds files() which returns files of the current changeset matching a given pattern or fileset query via the "set:" prefix.

rebase: rebase changesets in topo order (issue5370) (BC) There are two reasons that rebase should be done this way: 1. This would make rebasing faster because it would minimize the total number of files to be checked out in the process, as it don't need to switch back and forth between branches. 2. It makes resolving conflicts easier as user has a better context. This commit changes the behavior in "Test multiple root handling" of test-rebase-obsolete.t. It is an expected change which reflects the new behavior that commits in a branch are grouped together when rebased.

dispatch: make hg --profile wrap reposetup Move profiling.maybeprofile() from _runcommand to _dispatch() so that profiler output will include reposetup.
