Fix hg diff regression

add tests for push over http.

fix -I/-X when relative paths used or in subdir

hg.repository: many routines expect path to be a string even if empty.

fix bug in localrepo.changes. caused by 1e32e2fe8a677c391049d40b8794478976a0a914.

use commit time as mtime for file archives. now output from two run of "hg archive -t zip" is same.

archive: make "hg archive -t XXX -" to write to stdout

Fix cold cache diff performance cold cache diff performance has regressed in two ways. localrepo.changes has optimizations for diffing against the working dir parent that expect node1 to be None. commands.revpair() usage means that commands.dodiff() never sends node1 == None. This is fixed in localrepo.changes by checking against the dirstate parents. In the non-dirstate parents case, localrepo.changes does a loop comparing files without first sorting the file names, leading to random access across the disk.

change some repo messages in small ways. move "pushing" and "pulling" after repo create so error message and exit happens before messages printed. fix sshrepo parse error message.

make repo scheme table driven.

hg.repository: make protocol table driven. allows extensions to add new protocols.

mac os x: fixes for 10.2 from chris monson <monpublic@gmail.com>

http client: better work with authorization errors, broken sockets.

push over http: server side authorization support. new hgrc entries allow_push, deny_push, push_ssl control push over http. allow_push list controls push. if empty or not set, no user can push. if "*", any user (incl. unauthenticated user) can push. if list of user names, only authenticated users in list can push. deny_push list examined before allow_push. if "*", no user can push. if list of user names, no unauthenticated user can push, and no users in list can push. push_ssl requires https connection for push. default is true, so password sniffing can not be done.

push over http: client support. stream bundle data using PUT request.

push over http: server support. write "unbundle" verb for http.

localrepository.push: propagate return value

util: add limit to amount filechunkiter will read

Emacs: follow the revision usage policy of "hg diff" command. This patche makes "parent" as default revision of diff command.

Emacs: change directory of output buffer to the root of the repository.

Emacs: use `default-directory' if `buffer-file-name' is null. This patch allows you to co-operate with Mercurial in dired buffer.

Emacs: use delete-region instead of kill-* functions. This patch eliminates `kill-line' which taints kill-ring, and `kill-entire-line' which is specific for XEmacs.

Update keepalive.py to current CVS version of urlgrabber. This fixes a bug where the output of test-bad-pull would differ between python 2.3 and 2.4. Also update the expected output of this test.

patchbomb does not handle email time stamp plattform independent

http: query server for capabilities

remove use of undefined variable.

merge with self.

extend network protocol to stop clients from locking servers now all repositories have capabilities slot, tuple with list of names. if 'unbundle' capability present, repo supports push where client does not need to lock server. repository classes that have unbundle capability also have unbundle method. implemented for ssh now, will be base for push over http. unbundle protocol acts this way. server tells client what heads it has during normal negotiate step. client starts unbundle by repeat server's heads back to it. if server has new heads, abort immediately. otherwise, transfer changes to server. once data transferred, server locks and checks heads again. if heads same, changes can be added. else someone else added heads, and server aborts. if client wants to force server to add heads, sends special heads list of 'force'.

test-bad-pull: fix change in error output.

sshrepo: fix bug in error formatting.

hgweb: split "verbs" into methods.

http client: support persistent connections. uses keepalive module from urlgrabber package. tested against "hg serve", cgi server, and through http proxy. used ethereal to verify that only one tcp connection used during entire "hg pull" sequence. if server supports keepalive, this makes latency of "hg pull" much lower.
