profile: indent part of '__enter__'
We are about to introduce a try except. We start with adding the indent to make
the next patch clearer.
profile: remove now useless indent
We no longer rely on the value of '_output' so we can remove this conditional.
profile: use explicit logic to control file closing
We make the decision to close 'fp' more explicit instead of relying on the
implication of other variable. This makes the overall logic more robust.
profiling: move 'fp' closing logic into its own function
We are about to make the logic more robust and reuse it in more place, we start
by isolating what we have.
py3: use python3 hg in test-py3-commands.t at places where py2 hg was used
This patch fixes my mistakes where I added test in test-py3-commands.t as
`hg ...` where I forgot hg here refers to Python 2 mercurial.
test-dirstate-race: back out changeset

This is non-deterministic. In any case, I switched to using
debugrebuilddirstate in my WIP patches, which makes this moot.
revset: fix order of first/last members in compound expression (BC)
Suppose len(subset) >> len(ls) in common cases, 'subset & ls' should be
avoided whenever possible.
revset: filter first/last members by __and__ operation
This replaces 'if y in subset' with '& subset'. first(null) and last(wdir())
are fixed thanks to fullreposet.__and__.
This also revealed that first() and last() don't follow the order of the
input set. 'ls & subset' is valid only if the ordering requirement is 'define'
or 'any'.
