statprof: fix save and load Fix these functions even if they don't are used at the moment. Thanks to Yuya Nishihara for spotting that.

perftemplating: abort on incompatible version This is what the other debug commands do. Thanks to Yuya Nishihara for pointing this out.

templater: fix string representation of wrapped None flatten() and stringify() skip None, which means wrappedvalue(None).show() must return '' instead of 'None'. This isn't a problem right now, but we'll encounter it once we start using wrapped types extensively.

templater: show slightly better hint on map operation error It was super hard to find where the templater went wrong if a keyword was evaluated to '' or None.

templater: inline unwraphybrid() flatten() is the solo user of this function.

templater: drop hybrid-ness on unwrapvalue() Proxy methods are no longer necessary as list/dict functions go through the wrapped interface.

templater: mark .keytype as a private attribute

templater: abstract ifcontains() over wrapped types This allows us to make .keytype private. There's a minor BC that a hybrid dict/list of keytype=None now strictly checks the type of the needle. For example, {ifcontains(rev, files)} no longer matches a file named "1" at the rev=1. I made this change for consistency with the get(dict, key) function. We can restore the old behavior by making keytype=bytes the default if desired.

templater: inline wraphybridvalue() All wraphybridvalue() calls are now handled in the hybrid class.

templater: abstract min/max away I'm not certain how many get*() functions I'll add to the wrapped types, but getmin() and getmax() will allow us to optimize a revset wrapper.

stringutil: fix prettyrepr() to not orphan foo=<...> line

debugwalk: pretty-print nested matcher While porting filesets to composition of matchers, I found the original one-liner was hard to read.

debugwalk: show matcher output only if -v/--verbose And drop "egrep -v". This matches the behavior of "hg debugrevspec".

stringutil: promote smartset.prettyformat() to utility function It will be used by debugwalk.

profiling: introduce a "profiling.time-track" option This option allows to switch the time used by the statistical profiler from cpu to real time. Our goal is to profile IO intensive operations using the mercurial profiler.

statprof: also gather wall time Gathering wall time information is useful for operations that are IO (files, network) intensive. For now we only expose it in the final summary.
