revset: optimize "x & fullreposet" case If self is a smartset and other is a fullreposet, nothing should be necessary. A small win for trivial query in mozilla-central repo: revset #0: (0:100000) 0) wall 0.017211 comb 0.020000 user 0.020000 sys 0.000000 (best of 163) 1) wall 0.001324 comb 0.000000 user 0.000000 sys 0.000000 (best of 2160)

debugrevspec: show nesting structure of smartsets if verbose This shows how smartsets are constructed from the query. It will be somewhat useful to track problems such as stack overflow.

revset: add __repr__ to all smartset classes This is sometimes useful for debugging.

status: add relative directory help text (issue3835) Previously, it was difficult to find out how to display the status of files relative to your current working directory. This patch adds that knowledge to the help text.

diff: rename --relative option to --root The diff output format is unable to express files outside the directory so it makes sense to name this option --root instead of --relative.

revlog: make converting from inline to non-line work after a strip The checkinlinesize function, which converts inline revlogs to non-inline, uses the current transaction's "data" field to determine how to update the transaction after the conversion. This change works around the missing data field, which is not in the transaction after a strip.

check-code: in C code, prevent space before closing parenthesis

match: remove unused assignment of ctx ctx is consumed in __init__ to build match patterns and never used after that.

revert: comment that filesets are always evaluated against workingctx

revert: take fast path also when not reverting to '.' This speeds up 'hg revert -r .^ --all --dry-run' on the Mozilla repo from 4.081s to 0.826s. Note that 'hg revert -r .^ .' does not get any faster, since '.' does not make match.always() True. I can't think of a reason it would break anything, and if it does, it's clearly not covered by tests.
