workingctx: factor out post-status dirstate fixup We want to allow extensions to be able to add code to run inside the wlock.

merge with stable

profile: properly propagate exception from the sub-context manager Context manager has a mechanism to control extension propagation. It is not used by profiling right now, but making the code correct will help prevent bug in the future.

profile: close 'fp' in all cases There are no way for this to happen today, but better be safe than sorry, no one know how the code will evolve. We now make sure the file pointer is closed even is profiler is None.

profile: close 'fp' on error within '__enter__' Previously, error when initialying the profiler would forgot to explicitly close the file. Thank goes to Yuya Nishihara for spotting this.

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.
