darcs2hg: pause and resume support, date extraction from commit hash, does not break on empty commits

darcs2hg: improved logging

darcs2hg.py: use darcs patch hash as patch identifier The use of the patch name is dangerous when duplicate names exist. In case of a duplicate name the second patch and all its dependancies are merged into a single mercurial patch. The patch identifier (hash) is always unique.

adding local_hostname option to smtp configuration

Respect "Connection: close" headers sent by HTTP clients. A HTTP client can indicate that it doesn't support (or doesn't want) persistent connections by sending this header. This not only makes the server more compliant with the RFC, but also reduces the run time of test-http-proxy when run with python 2.3 from ~125s to ~5s (it doesn't affect it with python 2.4, which was already ~5s).

allow use of extensions in python hooks extensions are loaded with hgext_ prefix, try to use them if the module is not found in the normal path

diff: add -b/-B options

use __contains__, index or split instead of str.find str.find return -1 when the substring is not found, -1 evaluate to True and is a valid index, which can lead to bugs. Using alternatives when possible makes the code clearer and less prone to bugs. (and __contains__ is faster in microbenchmarks)

coding style: use spaces instead of tabs

bdiff: improve worst case behavior by 100x. on 5.8MB (244.000 lines) text file with similar lines, hash before this change made diff against empty file take 75 seconds. this change improves performance to 0.6 seconds. result is that clone of smallish repo (137MB) with some files like this takes 1 minute instead of 10 minutes. common case of diff is 10% slower now, probably because of worse cache locality. but diff does not affect overall performance in common case (less than 1% of runtime is in diff when it is working ok), so this tradeoff looks good.

Changed default timeout for run-tests.py from 30 to 180 seconds. As e.g. test-http-proxy already takes quite some time (about a minute here) and tests usually should clean up after themselves, the timeout should only be hit in case of other problems.

fix problems with external module handling. found by benoit boissinot. first fix is to not store module objects in commands.external dict, instead use module names for key into sys.modules. this prevents circular reference during cleanup of aborted transaction. second is to get name right during import of external module.

tests: record few more daemon pids to be safe

tests: add timeouts, make run-tests.py clean up dead daemon processes test timeout feature is needed for test with python 2.5 beta. if test does not complete in time (30 seconds is default), it is killed. some times daemon process used in test can be alive after the test is killed by user or by timeout. tests now record daemon pids into $DAEMON_PIDS and run-tests.py kills all living daemons after every test. final little change is to add newline to end of pid file printed by "hg serve", else "cat hg.pid >> $DAEMON_FILES" gives garbage.

run-tests.py: make tests use same python interpreter as test harness. this is wanted because some tests run python interpreter directly. must use same python interpreter in tests as in main harness or problems will happen because of e.g. different python abi if run-tests.py run with python 2.5 but system python is 2.4. fix is to see if system python is used and is named python. if no, put symlink called python at front of shell search path.

HTTPS: fix python2.3, persistent connections, don't explode if SSL is not available The urllib2 differences between python 2.3 and 2.4 are hidden by using keepalive.py, which also gives us support for persistent connections. Support for HTTPS is enabled only if there's a HTTPSHandler class in urllib2. It's not possible to have separate classes as handlers for HTTP and HTTPS: to support persistent HTTPS connections, we need a class that inherits from both keepalive.HTTPHandler and urllib2.HTTPSHandler. If we try to pass (an instance of) this class and (an instance of) the httphandler class to urllib2.build_opener, this function ends up getting confused, since both classes are subclasses of the HTTPHandler default handler, and raises an exception.

Fix annotate breakage

Merge context patches

Convert hg annotate to context api

convert hg cat to new context api

Add context helper functions to localrepo

Add context.py: changeset and file revision contexts

simplify make_filename, fix hg cat bug hg cat was using file-level rev/node ids for generating filename templates. This simplifies make_filename to only use changeset rev/node ids.

revlog: make lookup handle binary nodes

revlog: handle integer arguments to lookup

templater.firstline should handle empty strings

hgweb: fix unbundle. After the WSGI changes, even if a push over HTTP succeeds, apache complains about "Premature end of script headers: hgwebdir.cgi" and returns a "HTTP Error 500: Internal Server Error", making the local hg abort. The change to either of the files touched by this patch is enough to fix this, but I think changing both is a more robust solution.
