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.

keyword: obtain kwtemplater instance via repository at runtime Wrapper functions of keyword extension are defined in reposetup(), because they refer to kwtemplater instantiated in reposetup(). This patch makes them obtain kwtemplater instance via repository at runtime. For reviewability, this patch focuses on wrapper functions, which handle generator. This is a part of preparations for defining them statically.

keyword: obtain kwtemplater instance via repository at runtime Wrapper functions of keyword extension are defined in reposetup(), because they refer to kwtemplater instantiated in reposetup(). This patch makes them obtain kwtemplater instance via repository at runtime. This is a part of preparations for defining them statically.

keyword: make wrapped repository and kwtemplater refer to each other Wrapper functions of keyword extension are defined in reposetup(), because they refer to kwtemplater instantiated in reposetup(). But these functions can be defined statically, if kwtemplater can be obtained via repository at runtime. This is a part of preparations for defining them statically. To avoid cyclic reference, this patch makes kwtemplater use weakref to refer related repository instance.

keyword: add test for keyword expansion at serving multiple repositories This is safety for subsequent (and future) patches, which change function wrapping.
