revlog: raise an exception earlier if an entry is too large (issue4675) Before we were relying on _pack to error out when trying to pass an integer that was too large for the "i" format specifier. Now we check this earlier so we can form a better error message. The error message unfortunately must exclude the filename at this level of the call stack. The problem is that this name is not available here, and the error can be triggered by a large manifest or by a large file itself. Although perhaps we could provide the name of a revlog index file (from the revlog object, instead of the revlogio object), this seems like too much leakage of internal data structures. It's not ideal already that an error message even mentions revlogs, but this does seem unavoidable here.

wix: move library.zip and all *.pyd into a lib/ folder This makes the root install folder (on Windows) nice and tidy. The only files left in the root folder are: hg.exe python27.dll COPYING.rtf ReadMe.html the last of which was probably out-of-date 7 years ago

sshpeer: run the ssh command unbuffered This is necessary to use non-blocking IO base on polling. Such polling is needed to restore real time output with ssh peer. Changeset fce065538bcf is talking about 5x regression on Mac OS X when playing with this value. So we introduced our own buffering layer in previous changesets. This seems to keep the regression away (we are even issuing much less read).
