inotify: put STAT-specific query answer generation part in its own method

inotify: change protocol so that different query types can be supported.

inotify: Separate query sending logic from Server starting. Use a decorator around the public statusquery method of Client: start_server(query_to_server): try: query_to_server() except QueryFailed: [error recovery, inotify Server (re)starting] query_to_server() This way, introducing a new xxxquery Client method is easy: one has only to code the protocol part of xxxquery, ignoring errors, and decorating it using start_server to handle server recovery and (re)starts

inotify: modular architecture for inotify clients Put the socket init, query generation and response analysis in a more generic client class.

setup: another newline if version could not be established.

setup: add missing newline in warning

setup: read .hg_archival.txt for version info (issue1670) Previously, setup.py was enhanced to identify the Mercurial version from either .hg/ or mercurial/__version__.py. When archives are created using 'hg archive' or via hgweb, neither of those options are available. However, there is a .hg_archival.txt file in the root of the archive that has the information. This patch enhances setup.py to identify the Mercurial version from the .hg_archival.txt file when there is no .hg/ or mercurial/__version__.py available.

setup.py: subprocess instead of os.popen, sys.stderr.write instead of print Also check that .hg is a directory.

gendoc: add missing space in command synopsis

merge: give hint as to how to discover uncommitted changes Many users will try 'hg diff' here, and it will not show them missing files.

commands: standardize parents command meta data

i18n-da: synchronized

i18n: accurately generate hg.pot

hgcia, convert: escape backslashes in docstrings

commands: remove unnecessary quotes in backout help

test-merge-tools: windows fixes - /bin/cat does not exist, expect 'cat' - non-interactive mode is not correctly detected in pysh, force it

ui: honor interactive=off even if isatty()

Merge with crew-stable

hgwebdir: fix [collections] evaluation under Windows Virtual and real path separators are not the same under Windows.

cmdutil: mark string for translation

util: use "is" for True/False/None comparisons

remove: warn if unversionned files are specified (issue1454)

fetch: allow -r for remote repos

filelog encoding: move the encoding/decoding into store the escaping of directories ending with .i or .d doesn't really belong to filelog. we put the encoding/decoding in store instead, for backwards compat, streamclone and the fncache file format still uses the partially encoded filenames.

store: refactor the fncache handling put all the fncache file writing and reading in the same place.

hgweb: make hgwebdir handle dict/list paths the same as config paths Before this patch, the only way to get hgwebdir to honor the recursive paths was to create a config object or a config file with the recursive paths in it. This patch makes hgwebdir treat paths the same whether passed in as a list, tuple, config or however hgwebdir supports passing paths.

workingfilectx: always use the same filelog, even for renames workingfilectx() was using the "src" filelog in case the file was renamed in the working copy. For consistency, stop special-casing it. This allows us to remove some duplication between filectx and workingfilectx.

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).
