mq: backup local changes in qpop --force (issue3433)

pager: remove quiet flag With the pager running as a child process, exiting the pager doesn't result in a broken pipe message. To distinguish the exit broken pipe code from a mercurial abort we register the default action for SIGPIPE. This results in a 141 exit code instead of a 255. On windows SIGPIPE doesn't exists and a ValueError will be thrown.

pager: preserve Hg's exit code (and fix Windows support) (issue3225) This changes how the pager extension invokes the pager. Prior to this change, the extension would fork Hg and exec the pager in the parent process. This loses Hg exit code, and it doesn't work on Windows. Now the pager is invoked using the subprocess library, and an atexit handler is registered that makes Hg wait for the pager to exit before it exits itself. Note that if you exit the pager before Hg is done running, you'll get an exit code of 255, which is caused by Python blowing up due to a broken pipe. If you set pager.quiet=True, you'll get the OS-level return code of 141.

amend: preserve extra dict (issue3430)

parser: use PyInt_FromSsize_t in index_stats Eliminates mercurial/parsers.c(515) : warning C4244: 'function' : conversion from 'Py_ssize_t' to 'long', possible loss of data mercurial/parsers.c(520) : warning C4244: 'function' : conversion from 'Py_ssize_t' to 'long', possible loss of data mercurial/parsers.c(521) : warning C4244: 'function' : conversion from 'Py_ssize_t' to 'long', possible loss of data when compiling for Windows x64 target using the Microsoft compiler. PyInt_FromSsize_t does not exist for Python 2.4 and earlier, so we define a fallback in util.h to use PyInt_FromLong when compiling for Python 2.4.

localrepo: cleanup var names and comments Cosmetic cleanups. Fix comment typo referring to the notion of multiple tips. Make variable describing a generator end in 'gen'. Fix another var containing a node not to end with 'rev'.

transplant: manually transplant pullable changesets with --log

phases: stop modifying localrepo in writeroots() Also pass the phaseroots being written for clarity. repo._dirtyphases was already reset to False at call site.

phases: stop modifying localrepo in readroots() phasedefaults is also passed explicitely to help the casual reader understand where it is used without grepping all the sources.

phases: call filterunknown() in readroots() One less function manipulating localrepo state.
