revset: have all() filter out null revision I'm not sure if "all()" should filter out "null", but "all()" is stated as 'the same as "0:tip"' (except that it doesn't reorder the subset, I think.) This patch is intended to avoid exposing a fullreposet to graphmod.dagwalker(), which would result in strange drawing in future version: | o changeset: 0:f8035bb17114 | user: test | date: Thu Jan 01 00:00:00 1970 +0000 | summary: add a caused by: parents = sorted(set([p.rev() for p in ctx.parents() if p.rev() in revs])) We cannot add "and p.rev() != nullrev" here because revs may actually include "null" revision.

revset: drop unnecessary calls of getall() with empty argument If x is None, getall(repo, subset, x) == subset.

graphlog: do not bypass commands.log so that -fr works Since 8b4b9ee6001a, opts dict can be modified in commands.log() before calling cmdutil.graphlog().

histedit: add a config allowing changing histedit rule line length limit Since many users are using terminals wider than 80 chars there should be an option to have longer lines in histedit editor. Even if the summary line is shorter than 80 chars after adding action line prefixes (like "pick 7c2fd3b9020c") it doesn't fit there anymore. Setting it to for example 110 would be a nice option to have.

dirstate: make sure rootdir ends with directory separator (issue4557) ntpath.join() of Python 2.7.9 does not work as expected if root is a UNC path to top of share. This patch doesn't take care of os.altsep, '/' on Windows, because root should be normalized by realpath().

i18n-de: fix a typo in the german translation

histedit: fix style of new error message - lowercase - no punctuation - brief - short node

Makefile: allow setting HGTESTFLAGS in shell environment for TESTFLAGS I keep wanting to run 'make tests', but I forget to set TESTFLAGS='-j 16' or whatever is reasonable for my machine. This lets me just set it once in my shell settings and forget it.

Makefile: introduce testpy-% target for testing with a specifc Python This makes it easy to do 'make testpy-2.4.6 TESTFLAGS="-j 16"' and the Makefile will build Python if needed and then run tests (with -j 16) with the resulting Python. You can set the environment variable HGPYTHONS to a nice location on your machine to cache the Python builds globally. If that's not set, it builds them inside build/pythons.

extdiff: expand tildes and variables in paths to user-supplied diff programs
