use 'x is None' instead of 'x == None' The built-in None object is a singleton and it is therefore safe to compare memory addresses with is. It is also faster, how much depends on the object being compared. For a simple type like str I get: | s = "foo" | s = None ----------+-----------+---------- s == None | 0.25 usec | 0.21 usec s is None | 0.17 usec | 0.17 usec

patch: simplify Boolean expression slightly The context variable is either True, False or None. Abbreviate it as C and we get the following truth table where the second column is the original expression and the third column is the new expression: C | C or C == None | C is not False True | True | True False | False | False None | True | True

mq: new method invalidate Introduce method invalidate (similar to dirstate and repo).

mq: only read files when needed use util.propertycache as in dirstate

tests: replace #...# syntax with {...}

match: use self.exact instead of lambda self.exact uses a set and does not need an extra copy of the files

dirstate: use quicker matchfn() instead of match() everywhere matchfn does the same as match(), but a direct "link"

patchbomb: don't localize Date headers

alias: a0104303f400 did not correctly handle whitespace in the args

update --clean: do not unlink added files (issue575)

templater: lowercase error message Changing this messages should be safe: automated scripts ought to have debugged their templates and wont grep for this error message.

util: use set instead of dict

localrepo: update commit*() docstrings

patchbomb: with --in-reply-to, still thread message under first in series When specifying --in-reply-to for a message M, have [M] [0/2] [1/2] [2/2] instead of [M] [0/2] [1/2] [2/2] which is more consistent with the way messages are being threaded when --in-reply-to is not used.

merge with mpm

patchbomb: minor typo and language fixes

patchbomb: clarify diffstat usage

patchbomb: fix inexact description of the messages threading Each message refers only to the first of the series.

coal/paper: minimize whitespace differences in CSS files

coal/paper: equal heights for file and annotate views

spartan: ensure equal heights for file and annotate views The display used to jump up and down when switching from the file view to the annotate view. It now stays still: when switching from the file view to the annotate view it looks like the file content is simply right-shifted to make room for the author names.

coal/paper: simplify margin and padding CSS rules

spartan: simplify CSS colors (#xxxxxx -> #xxx)

coal/paper/spartan: remove extra line break in annotate view

commit: tidy up mergestate slightly

commit: drop unneeded dirstate invalidate logic We no longer touch the dirstate in the middle of a commit, so a failing commit doesn't require invalidating the dirstate.

commit: some tidying - simplify handling of 'close' - kill silly wlock=None - sort/uniq files later

commit: remove unused lock var

commit: move description trimming into changelog

commit: simplify manifest commit

commit: explain how to abort commit in editor

commit: move editor outside transaction The commit editor is now invoked before files and manifest are committed. The editor is now run with only the wlock held and aborting an edit no longer requires rolling back a transaction. Changes to files during a commit still result in undefined behavior. (This is preliminary work for committing subrepositories)
