tests: sort import lines in tinyproxy.py

tests: sort import lines in failfilemerge.py

tests: sort import lines in dumbhttp.py This series is an attempt to enable import-checker.py for tests/**.py, but it turned out not easy. Since many tests have been ported to absolute_import without the coverage, import-checker.py reports a lot of errors right now. Should we enable import-checker.py without fixing all of them so that we won't get more errors?

chgserver: change random state after fork Before this patch, extensions expecting a different random state per command will break since the chg request handler will inherit a same random state from the parent daemon process. This patch addresses the issue by calling random.seed() after fork.

chg: make connect debug message less repetitive Before this patch, "connect to" debug message is printed repeatedly because a previous patch changed how the chg client decides the server is ready to be connected. This patch revises the places we print connect debug messages so they are less repetitive without losing useful information.

chgserver: use relative path at socket.bind Before this patch, if the server address is long, the server will fail to listen and throw the error: socket.error: AF_UNIX path too long It is because AF_UNIX path usually has a very short length limit (107 chars on common platforms, see sys/un.h). This patch addresses the issue by using relative path instead. Therefore the directory length does not matter. It helps run tests with chg using a long $TMPDIR.

chgserver: move args copying logic to the correct place A previous patch moved it to an incorrect place. Since dispatch._earlygetopt has side effects on args, we need to move it to the place before _earlygetopt.

hghave: add hg06..hg39 hg output varies by version, this helps the hgbook hg 0.6 did not have a version command, so special case it... hg 0.7-0.8 had a version command which returned unknown... hg 0.8 added a --date flag to annotate hg 0.9 had a working version command!

hghave: use checkvers for bzr114

hghave: replace has_svn13/has_svn15 with checkvers This would make it possible to easily add a svn14 or svn16 or...

hghave: update cvs112 description Classic cvs stopped at 1.11. There was a beta version 1.12 that never had a final release. CVS NT is a fork which starts with versions numbered 2.0+. We should have an hg have cvsnt, but to test that requires getting cvsnt, and it's commercial / its older source versions are hard to find.

parser: move parsererrordetail() function from revset module This will be used by common alias functions introduced by future patches.

hgweb: fix links in atom-branches

revset: prevent infinite recursion on pypy as explained in the commit, __len__ cannot do [x for x in self] because that can potentially call __len__ again, causing infinite recursion

pypy: fix doctests for pypy optimizations PyPy would sometime call __len__ at points where it things preallocating the container makes sense. Change the doctests so they're using generator expressions and not list comprehensions

largefiles: replace invocation of os.path module by vfs in reposetup.py This commit is part of bigger effort described in 'Windows UTF-8' plan.

largefiles: replace invocation of os.path module by vfs in overrides.py This commit is part of bigger effort described in 'Windows UTF-8' plan. It is not changing all invocations but the ones where change is obviously correct and doesn't require complicated changes.

bundle: warn when update to revision existing only in a bundle (issue5004) Now its done silently, so unless user really knows what he is doing will be suprised to find that after update 'hg status' doesn't work. This commit makes also merge operation warns about missing parent when revision to merge exists only in the bundle.
