Fix issue 653: symlinks checkout failure on non-supporting platforms

test-oldcgi: replace shebangs with explicit python calls to help pysh.

test-issue352: skip tests if platform does not support EOL in paths.

hghave: detect support for EOL in paths.

test-git-import: fake executable permissions.

hghave: detect executable permission availability.

test-clone-failure: fake output upon fifo unavailabity

hghave: detect FIFO availability

Skip test-archive-symlinks if symlinks are not available

posixfile_nt: '+' should allow read access. This fixes unexpected I/O error on committing many files due to cset:8a53b39cd402 (r4902 in crew).

posixfile_nt: '+' was understood as read mode instead of update.

httprepo: quote the path part of the URL This should fix a 'hg clone "http://hg.example.org/path with spaces/"' The code tries to do the right thing when the user passes a path that's already escaped in part (e.g. "http://hg.example.org/path%20with spaces/"). If we're redirected, urllib2 will happily follow the URL it's given without escaping anything. I'm not sure what we would have to hook to work around that.

dirstate: fix rebuild; add a test If rebuild calls invalidate, it will just queue a (re)read of the dirstate file, while what we really want is to empty the current state.

hgweb: don't use os.path.join to build URL parts

hgwebdir: change os.sep in the name of repos to "/"

Simplify/correct finding the hg executable (fixes issue644) Simply use find_exe('hg') as the default value for $HG and require to manually set it if you have special requirements. While the default will not always be 100% correct (i.e. the identical hg version) for many users it is and for the others the hg executable found in the PATH should do most things correctly. Developers or other users with multiple installs can set $HG or run something like util.set_hgexecutable in their shell or python scripts. Additionally util.hgexecutable() is now available so extensions can access the value with a public interface, too.

archive: abort on empty repository. Fixes #624.

del transaction before lock before wlock This way rollbacks happen while the repo is still locked. Deleting lock before wlock is not strictly necessary, but is more consistent with the locking order.

merge: do early copy to deal with issue636 Without copies/renames, merges source names are 1:1 with their targets. Copies and renames introduce the possibility that there will be two merges with the same input but different output. By doing the copy to the destination name before the merge, the actual merge becomes 1:1 again, and no source is the input to two different merges. - add a preliminary scan to applyupdates to do copies - for the merge action, pass the old name (for finding ancestors) and the new name (for input to the merge) to filemerge - eliminate the old post-merge copy - lookup file contents from new name in filemerge - pass new name to external merge helper - report merge failure at new name - add a test

localrepository: allow rawcommit to commit with an empty message

Fix re: and glob: patterns in .hgignore (reported by Brad Schick) relglob: and relre: were already detected for a long time, so I kept this undocumented functionality, especially as it was already tested in test-hgignore.

merge: don't forget to update the dirstate for exec bit changes

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.

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.
