scmutil: proxy revrange() through repo to break import cycles This was one of the hardest import cycles as scmutil is widely used and revset functions are likely to depend on a variety of modules. New repo.anyrevs() does not expand user aliases by default to copy the behavior of the existing repo.revs(). I don't want to add new function to localrepository, but this function is quite similar to repo.revs() so it won't increase the complexity of the localrepository class so much.

revset: split language services to revsetlang module (API) New revsetlang module hosts parser, tokenizer, and miscellaneous functions working on parsed tree. It does not include functions for evaluation such as getset() and match(). 2288 mercurial/revset.py 684 mercurial/revsetlang.py 2972 total get*() functions are aliased since they are common in revset.py.

revset: import set classes directly from smartset module Follows up 1be65deb3d54.

help: add pointer how to narrow list of resolved/unresolved files (issue5469)

shelve: add -n/--name option to unshelve (issue5475) This makes using shelve/unshelve more consistent because shelving can be done using name option and unshelving as well. Author of the idea of this improvement and solution is joshgold.

smartset: use native set operations as fast paths For set operations like "&" and "-", where we know both basesets have their sets ready, and the first set is sorted, use the native Python set operations as a fast path. Note: "+" is not optimized as that will break the ordering. This leads to noticeable improvements on performance: revset | before | after | delta ---------------------------------------------------------------- draft() & draft() & draft() & draft() | 776 | 477 | -39% draft() + draft() + draft() + draft() | 2849 | 2864 | draft() - draft() + draft() - draft() | 943 | 240 | -75% draft() - draft() - draft() - draft() | 557 | 197 | -64% (time measured in microseconds)
