export: map wctx.node() to 'ff...' node id (issue5438)

revset: add support for integer and hex wdir identifiers As I said before, partial 'ff...' hash isn't supported yet.

localrepo: map integer and hex wdir identifiers to workingctx changectx.__init__() is slightly modified to take str(wdirrev) as a valid integer revision (and raise WdirUnsupported exception.) Test will be added by the next patch.

revlog: map rev(wdirid) to WdirUnsupported exception This will allow us to map repo["ff..."] to workingctx. _partialmatch() will be updated later. I tried "return wdirrev" in place of raising the exception, but earlier exception seemed better.

scmutil: introduce binnode(ctx) as paired function with intrev(ctx) It seemed silly to convert ctx.hex() back to binary to use node.hex/short(), or to use [:12] instead of node.short() because ctx.node() could be None. Eventually I want to change wctx.rev() and wctx.node() to return wdirrev and wdirid respectively, but that's quite big API breakage and can't be achieved without some compatibility wrappers.

merge: use scmutil.intrev() to sort ctx objects This moves wctx to the last, but that shouldn't matter. Only the order of stored revisions is important.

scmutil: pass ctx object to intrev() This makes it slightly easier to sort basectx objects by key=scmutil.intrev. We're most likely to have ctx objects where changectx/workingctx abstraction is necessary, so this won't increase the abstraction overhead.

setup: do not overwrite local __modulepolicy__.py on out-of-source build Since the default policy is selected depending on setup options, "make install" shouldn't overwrite in-source __modulepolicy__.py generated by "make local".

status: don't crash if a lookup file disappears This can happen if another process (even another hg process!) comes along and removes the file at that time. This partly resolves issue5584, but not completely -- a bogus dirstate update can still happen. However, the full fix is too involved for stable.

match: simplify nevermatcher Most of it does the same as its superclass, so it can simply be removed. It also seems to make more sense for it to use relative paths, as we do for everything except alwaysmatcher, although nevermatcher.uipath() will probably never get called anyway, so it won't matter.

annotate: restructure formatter output to be nested list (BC) Annotate data should be in [(file, [line...])...] form, but there was no API to represent such data structure when I ported it to formatter. Now we have fm.nested() and the -T option is still experimental, so we can fix the data format.

annotate: rename formatter variable So we can add a nested 'fm' of narrow scope.

setup: prevent setuptools from laying an egg Previously, test-hghave.t was failing on Windows (and on Linux if $FORCE_SETUPTOOLS was set) with the following: --- c:/Users/Matt/Projects/hg/tests/test-hghave.t +++ c:/Users/Matt/Projects/hg/tests/test-hghave.t.err @@ -19,7 +19,11 @@ > foo > EOF $ run-tests.py $HGTEST_RUN_TESTS_PURE test-hghaveaddon.t + warning: Testing with unexpected mercurial lib: c:\Users\Matt\Projects\hg\mercurial + (expected ...\hgtests.mu9rou\install\lib\python\mercurial) . + warning: Tested with unexpected mercurial lib: c:\Users\Matt\Projects\hg\mercurial + (expected ...\hgtests.mu9rou\install\lib\python\mercurial) Augie relayed concerns[1] about the first attempt at this, which also excluded 'install_egg_info'. All that needs to be excluded to avoid the egg and make the test work is to filter out 'bdist_egg'. (Actually, the body of this class could simply be 'pass', and 'bdist_egg' still isn't run. But that seems to magical.) Also note that prior to this (and still now), `make clean` doesn't delete the 'mercurial.egg-info' that is generated by `make install`.

bitmanipulation: add missing include of string.h That's where memcpy() is declared.

py3: add test to show `hg update` and `hg identify` works on Python 3

py3: add a test to show `hg diff` works on Python 3

py3: implement __bytes__ for committablectx Before this method, calling bytes on workingctx or memctx calls basectx.__bytes__ since the magic method was not defined for this class. When it calls the method from basectx class, it returns TypeError because None is passed into it. After this commit `hg update -C` works on Python 3 if eol is not enabled.

py3: convert exception to bytes to pass into ui.warn() Here encoding.strtolocal() is used because exc maybe an IOError which could contain a valid non-ascii unicode.

py3: convert bool variables to bytes before passing into ui.debug() We can't pass unicodes to ui.debug() and hence we need to convert things to bytes before passing them.

py3: use dict.update() instead of constructing lists and adding them dict.items() returned a list on Python 2 and whereas on Python 3 it returns a view object. So we required a work around. Using dict.update() is better then constructing lists as it should save us on gc churns.
