hghave: add "chg" flag to skip tests that can't be compatible with chg Several tests fail with chg for several reasons such as loaded chgserver extension, running uisetup() per server instead of per runcommand, etc. Since these tests can't/shouldn't be changed to be chg friendly, we need a flag to skip them. This patch explicitly drops CHGHG environment if chg isn't involved. This way, hghave can just check if CHGHG exists.

tests: add new test for #! shebang lines * use #!/bin/sh not e.g. #!/usr/bin/sh * use #!/usr/bin/env python not e.g. #!/usr/bin/python

largefiles: introduce push --lfrev to control which revisions are pushed The default of pushing all largefiles referenced in outgoing revisions is safe, but also expensive and sometimes not what is needed. We thus introduce a --lfrev option, similar to what pull already has. By specifying an empty set of revisions (or null), it is possible to get lazy (and insecure!) pushes of revisions without referenced largefiles, similar to how pull works.

largefiles: don't access repo.changelog directly in getlfilestoupload Make it possible to pass both nodes and revisions to getlfilestoupload.

localrepo: refactor prepushoutgoinghook to take a pushop prepushoutgoinghook was introduced in 6c383c871fdb and largefiles is the only in-tree use of it. Refactor it to be more useful for other use cases in largefiles.

parser: unify parser function of alias declaration and definition We no longer have to keep them separately.

revset: unify function that parses alias declaration and definition We no longer need separate parsers. Only difference between _parsealiasdecl() and _parsealiasdefn() is whether or not to flatten 'or' tree. Since alias declaration should have no 'or' operator, there was no practical difference.

parser: move alias definition parser to common rule-set class The original _parsealiasdefn() function is split into common _builddefn() and revset-specific _parsealiasdefn(). revset._relabelaliasargs() is removed as it is no longer used. The doctests are ported by using the dummy parse().

parser: move _relabelaliasargs() to common rule-set class This has no doctest because it will be covered by _builddefn() introduced by the next patch. revset._relabelaliasargs() will be removed soon.

parser: move alias declaration parser to common rule-set class The original _parsealiasdecl() function is split into common _builddecl() and revset-specific _parsealiasdecl(). And the original _parsealiasdecl() call is temporarily replaced by rules._builddecl(), which should be eliminated later. The doctests are mostly ported by using the dummy parse(), but the test for 'foo bar' is kept in _parsealiasdecl() as it checks if "pos != len(decl)" is working. Also, 'foo($1)' test is added to make sure the alias tokenizer can handle '$1' symbol, which is the only reason why we need _parsealiasdecl().
