origpath: move from cmdutil to scmutil This is a lower-level function so it doesn't need to be in cmdutil, and putting it here avoids a bunch of potential import cycle issues.

revlog: remove unnecessary cache validation in _chunks Previously, we likely called _chunkraw() multiple times in order to ensure it didn't change out from under us. I'm pretty certain this code had its origins in the days where we attempted to have thread safety of localrepository and thus revlog instances. revlog instances are already not thread safe for writing. And, as of Mercurial 3.6, hgweb uses a separate localrepository instance per request, so there should only be a single thread reading a revlog at a time. We more or less decided that attempting to make classes like revlog thread safe is a lost cause. So, this patch removes thread safety from _chunks. As a result, we make one less call into _chunkraw() when the initial read isn't serviced by the cache. This translates to savings of 4 function calls overall and possibly prevents the creation of an additional buffer view into the cache. I doubt this translates into any real world performance wins because decompression will almost certainly dwarf time spent in _chunks(). But it does make the code simpler, so it is an improvement.

revlog: return offset from _chunkraw() A subsequent patch will refactor _chunks() and the calculation of the offset will no longer occur in that function. Prepare by returning the offset from _chunkraw().

verify: get rid of some unnecessary local variables Now that all the major functionality has been refactored out, we can delete some unused local variables.

verify: move changelog verificaiton to its own function This makes verify more modular so extensions can hook into it.

verify: move manifest verification to its own function This makes verify more modular, making it easier for extensions to extend.

verify: move file cross checking to its own function This is part of making verify more modular so extensions can hook into it.

verify: move filelog verification to its own function This makes verify more modular so extensions can hook in more easily.

verify: move checkentry() to be a class function This is part of making verify more modular so extensions can hook into it.

verify: move checklog() onto class This is part of an effort to make verify more modular so extensions can hook into it.

dockerrpm: fix CentOS 5 RPMs (issue4977) The older rpmbuild in CentOS 5 fails if some of the output directories have not been created yet. This change results in creating those directories.

check-code: enforce strict spacing around assignment

cleanup: remove superfluous space after space after equals (tests)

tests: make a stab at approximating wall-clock times Vaguely empirical observations: * ".py" tests are about an order of magnitude faster than ".t" tests * dividing size by 1000 gives an approximation to wall-clock run time (in seconds) that is not completely ridiculous.
