dagop: make walk direction switchable so it can track descendants # ancestors(tip) using hg repo 2) 0.068527 3) 0.069097

dagop: factor out generator of ancestor nodes # ancestors(tip) using hg repo 1) 0.068976 2) 0.068527

dagop: factor out pfunc from revancestors() generator This generator will be reused for tracking descendants with depth limit. # ancestors(tip) using hg repo 0) 0.065868 1) 0.068976

dagop: use smartset.min() in revdescendants() generator All callers pass the result of revset.getset(), which should be a smartset.

dagop: change revdescendants() to include all root revisions Prepares for adding depth support. I want to process depth=0 in revdescendants() to make things simpler. only() also calls dagop.revdescendants(), but it filters out root revisions explicitly. So this should cause no problem. # descendants(0) using hg repo 0) 0.052380 1) 0.051226 # only(tip) using hg repo 0) 0.001433 1) 0.001425

test-revset: add a few more tests of descendants() I'll add depth support to descendants().

dagop: unnest inner generator of revdescendants() This just moves iterate() to module-level function.

smartset: fix default value of abstractsmartset.sort() It's unused, but it shouldn't lie.

keyword: wrap functions only once at loading keyword extension Before this patch, some functions are wrapped in reposetup(), but this causes redundant nested wrapping, if two ore more repositories enable keyword extension (e.g. hgweb serves multiple repositories). Now, there is no need to define these wrapper functions in reposetup(), because previous patches made them not directly refer to kwtemplater instanciated in reposetup(). This patch factors these wrapper functions out from reposetup(), and uses them to wrap functions only at once at loading keyword extension.

keyword: use _keywordkwt of repository instead of kwtools['templater'] Now, kwtemplater instance can be obtained via _keywordkwt property of repository.
