amend: abort if unresolved merge conflicts found (issue5805) It was checked by repo.commit() before e8a7c1a0565a "cmdutil: remove the redundant commit during amend."

debugwireproto: close the write end before consuming all available data And make it read all available data deterministically. Otherwise util.poll() may deadlock because both stdout and stderr could have no data. Spotted by the next patch which removes stderr from the fds.

hook: ensure stderr is flushed when an exception is raised, for test stability Windows has had issues with output order in test-ssh-proto-unbundle.t[1] since it was created a few weeks ago. Each of the problems occurred when an exception was thrown out of the hook. Now the only thing blocking D2720 is the fact that the "abort: ..." lines on stderr are totally AWOL. I have no idea where there are. [1] https://buildbot.mercurial-scm.org/builders/Win7%20x86_64%20hg%20tests/builds/541/steps/run-tests.py%20%28python%202.7.13%29/logs/stdio

wireproto: raise ProgrammingError instead of Abort This isn't a user-facing error and can only be caused by bad Python code. Thanks to Yuya for spotting this. Differential Revision: https://phab.mercurial-scm.org/D2777

py3: open patch file in binary mode and convert eol manually Here we don't introduce a reader wrapper since it wouldn't be easy to make read(n) handle partial data and length correctly.
