revset: extend fullreposet to make "null" revision magically appears in set As per fullreposet.__and__, it can omit the range check of rev. Therefore, "null" revision is accepted automagically. It seems this can fix many query results involving null symbol. Originally, the simplest "(null)" query did fail if there were hidden revisions. Tests are randomly chosen. fullreposet mimics the behavior of localrepo, where "null" revision is not listed but contained.

revset: duplicate spanset.__contains__ to fullreposet for modification 1d7a2771aa36 says we should avoid function calls in __contains__, so super(fullreposet, self).__contains__(rev) is not an option. Actually the super call doubled the benchmark result of trivial query: revisions: 0) 678f53865c68 (tip when I wrote this patch) 1) rev == node.nullrev or super(fullreposet, self).__contains__(rev) revset #0: tip:0 0) wall 0.008441 comb 0.010000 user 0.010000 sys 0.000000 (best of 282) 1) wall 0.016152 comb 0.010000 user 0.010000 sys 0.000000 (best of 146)

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

setup.py: do not install c extensions on pypy These extensions are slower on pypy because pypy has a JIT compiler. And also, they often do not compile (it depends on the pypy configuration).

copyright: update to 2015 Many files and translations have an outdated copyright date. Change that to the correct "2005-2015" dates.

changegroup: emit full-replacement deltas if either revision is censored To ensure that exchanged deltas in the presence of censored revisions can always be applied to the recipient repository, the deltas must replace the entire base text. To make this restriction reasonably enforceable, the delta must do so with a single patch operation. For background and broader design of the censorship feature, see: http://mercurial.selenic.com/wiki/CensorPlan

log: make -fr show complete history from the given revs Right now it's very obtuse to show the history of a particular rev (hg log -r 'reverse(::foo)'). This changes the -f option to make it follow history for the revs specified by -r. The current -f -r behavior is to limit the result of -r to only the commits that are ancestors of the current working copy. Changing this is a bit of a BC break, but the old behavior is A) rare, B) easy to emulate (& ::.), and C) currently undefined. The new behavior is frequently requested enough that I think the change is worth it.
