revlog: avoid some unnecessary seek/tell syscalls

manifest: speed up creation of the manifestdict - fold iteration and rawset into parse - avoid creating extra new strings with [:] where possible - speed up node.bin

lazyparser.findnode: fix typo and s/rfind/find/ There's no reason to use reverse string search and it's slightly slower

lazyindex: speed up __getitem__ This function is fairly performance sensitive, so we make a couple ugly tweaks: - keep all entries packed so we needn't test entry types - fold index lookup/load into unpack call to eliminate local variable setting

lazyparser: up the blocksize from 512 bytes to 64k

revlog: implement a fast path for heads

revlogio: speed up parsing - precalcuate ending offset - pull some variables into local scope - separate inline and out of line code paths

revlog: eliminate diff and patches functions call mdiff variants directly

revlog: speed up chunkcache - use a reasonable cache size - avoid an extra copy when we pull in big revs

revlog: some basic code reordering

revlog: abstract out index entry packing This lets us remove most of the remaining v0/v1 logic from revlog

revlog: simplify revlog.__init__ - move stat into io helper - get rid of self.defversion and self.indexstat - fold _load into __init__

revlog: mark cache private

revlog: pull chunkcache back into revlog

revlog: change _inline from a function to a variable

revlog: simplify addrevision - remove unused defaults for p1, p2, and text - reduce some if/else - use better variable names - remove some extra variables - remove some obsolete corner tests - simply first entry handling for revlogng - simply inline vs outofline writeout

revlog: some codingstyle cleanups

revlog: add a magic null revision to our index We expand our index by one entry so that index[nullrev] points to a unique entry, the null revision. This naturally eliminates numerous extra tests in the performance-sensitive index access functions, most of which are now trivial again. Adding new entries is now done with insert(-1, e) rather than append(e).

revlog: change accesses to index entry elements to use positive offsets

revlog: parse revlogv0 indexes into v1 internally This lets us eliminate lots of special case code in our performance-sensitive index accessors.

revlog: only allow lazy parsing with revlogng files This will allow us to store indices in memory in a single entry format

revlog: simplify the v1 immediate parser - read all the data at once (large files are handled by the lazy parser) - cache the entire file for inline revlogs - simplify looping

revlog: set the threshold for lazy parsing higher A typical machine can parse a 1MB index in well under a second

revlog: simplify the v0 parser

revlog: add revlogio interface This lets us separate the logic for different on-disk revlog formats from the main revlog logic.

revlog: regroup parsing code

transactions: avoid late tear-down (issue641) We use weak references (ugh) to avoid having to manually delete transaction references out of each call frame when an exception occurs.

hgk: enable mouse wheel under Windows. For some reason, MouseWheel events are not routed under windows even in latest ActiveTcl 8.4.15 while they are under linux and macosx. These events are activated using code supplied with Tcl Tip 171: <http://www.tcl.tk/cgi-bin/tct/tip/171.html>. Strangely, the Tip code almost work but generates some unexpected infinite loop which is fixed using a simple boolean to check reentrancy.

hgk: enable mouse wheel on MouseWheel events. At this point, mouse wheel still does not work under Windows.

addremove: print meaningful error message if --similar not numeric

Merge with crew

revlog: privatize some methods

revlog: delete unused function makenode

revlog: raise offset/type helpers to global scope

Make repo locks recursive, eliminate all passing of lock/wlock

Use a weakref for recursive transactions

Use try/finally pattern to cleanup locks and transactions

repo locks: use True/False

rename and simplify do_lock

simplify dirstate fixups in repo.status()

dirstate: add doesn't need to call stat

use context for part of localrepo status

context: add __contains__, __getitem__, and __iter__

dirstate: get rid of default args for status

dirstate: make filterfiles private

dirstate: add __contains__ and make __getitem__ more useful dirstate.state(f) == '?' -> f not in dirstate dirstate.state(f) -> dirstate[f]

dirstate: make wjoin function private

dirstate: break update into separate functions

dirstate: use True and false for _dirty

test-alias: Removed fallback to parentui, no longer needed since 10afa3fab6b4

merge with crew-stable

Make [defaults] in .hg/hgrc work.

fix bogus close spotted by pychecker (no close() in global scope)

Remove unused pprint import and the commented line which used it before.

Use format string for lockname again (was changed by 3e25a6eb5c9a)

Backout ad09ce1d393c and replace ''' with """ to make some highlighting happy. I have tried Debian's default emacs and the current CVS version. Default emacs doesn't have highlighting enabled (and being emacs-illiterate I don't know how to enable it) and the CVS emacs' Python highlighting has no problems with ' characters here.

removed trailing whitespace

fix unused variables reported by pychecker

churn: get current terminal width if possible
