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: add checkvers function

hghave: add docstring for check

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.

tests: fix builtin module test on pypy On pypy datetime and cProfile are modules written in Python, not in C. For the purpose of this test, just list them explicitely as builtins, which silences warnings about them being imported before stdlib modules.

hgweb: generate last change date for an empty atom-bookmarks feed (issue5022) RFC 4287 states that atom feeds must have an <updated> element, so let's add one even when repo doesn't have a single bookmark.

hgweb: sort bookmarks in revlog order of their nodes Changes, branches and tags are already in revlog order on /summary, /branches and /tags, let's now make bookmarks be sorted by the same principle. It's more helpful to show more "recent" bookmarks on top. This will affect /bookmarks page in all styles, including atom, rss and raw, and also /summary page. Bookmarks are sorted using a (revision number, bookmark name) tuple.

hgweb: sort bookmarks early Let's do the same thing that /tags page does. It gets sorted tags and then if it needs the latest only, it just slices the first item from the list. Since it's a slice and not a min(), it doesn't throw an exception if the list is empty. This fixes HTTP 500 error from issue5022.

hgweb: add parents to json-log (issue5074) Entries prepared in webutil.changelistentry() skip showing parents in the trivial case when there's only one parent and it's the previous revision. This doesn't work well for the json-log template, which is supposed to just dump raw data in an easy-to-parse format, so let's provide all parents as another keyword: allparents. Using a lambda function here means that the performance of templates that don't use allparents won't be affected (see 41957e50e109).

revset: make _parsealiasdecl() simply return the original parsed tree It wasn't necessary to reconstruct the same tuple.

revset: inline isvalidfunc(), getfuncname() and getfuncargs() See the previous commit for why. These functions are also trivial.

revset: inline isvalidsymbol() and getsymbol() into _parsealiasdecl() Since I'm going to extract a common alias parser, I want to eliminate dependencies to the revset parsing rules. These functions are trivial, so we can go without them.

revset: remove redundant checks for parsed tree of alias If tree is a tuple, it must have at least one element. Also the length of node tuple is guaranteed by the syntax elements. (e.g. 'func' must have 3 items.) This change will help inlining these trivial functions in future patches.
