contexts: improve filectx eq test

patchbomb: add --desc, to specify a file containing a series description

merge: fix unnecessary rename merges on linear update (issue631) If one side's revision is identical to the ancestor, we skip the rest of the copy detection logic.

convert: Use clone's behaviour for the default destionation name. Adjusted the documentation for this and for the fact that the destionation is created even if a name is specified.

test-symlink-basic: require symlinks availability

Add hghave utility and run-tests.py support. hghave detects system features like symlinks availability at run-time. Tests can be skipped by starting them with: "$TESTDIR/hghave" symlink || exit 80 The 80 exit status triggers hghave output handling by run-tests.py. Also, tests output can be locally patched on the fly to match reference output.

run-tests: extract correct status when script terminates with exit

diff: correctly handle combinations of whitespace options

hg grep: handle re.compile errors & update tests/test-grep

typo fix

Re: mercurial.el and hg-version-other-window hg-version-other window is unimplemented in mercurial.el. The version below works for me, YMMV.

Use isinstance instead of type == type

convert: record the source revision in the changelog

Use wsgi.url_scheme instead of ad-hoc CGI checks. Instead of each place in hgweb_mod that needs to check for SSL or get the protocol scheme (http vs. https) doing it ad-hoc, make them just look at the wsgi.url_scheme which because of previous patches is now always set correctly.

cosmetics

Make hg serve set the wsgi.url_scheme property correctly. This fixes the bug where hg serve with SSL will always detect the wrong urlbase for templates. This is also part of unifying the CGI interface and hg serve interface to both use standard wsgi.

Handle CGI SSL detection via HTTPS environment better. Some servers send on/off, 0/1, yes/no, and may be upper or lower case. This fix will handle all of those permutations. It was inspired by the detection done in in some other wsgi python web applications I looked at.

Make {urlbase} work in templates when https is used.

replace .hgtags instead of appending to it when doing a raw commit

handle nonexistent .hgtags in raw _tag

Export extra in _tag so convert can set the branch of a tag

archive: abort on empty repository. Fixes #624.

mq: improve qclone error handling when patch directory is not a repository.

Fix test-debugcomplete for new --certificate option

Add SSL support to hg serve, activated via --certificate option

Correct inadvertent line ending change.

Fix for win32text corrupting files that have CRLF line endings. (issue302) Also generate a warning when encountering this condition. From Shun-ichi Goto in attachment win32text-patch3.txt for issue 302.
