posix: make poll() restart on interruption by signal (issue5452) select() is a notable example of syscalls which may fail with EINTR. If we had a SIGWINCH handler installed, ssh would crash when the terminal window was resized. This patch fixes the problem.

color: load 'colortable' from extension using an 'extraloader' Now that we have the '_style' dictionary in core, we can use the clean and standard 'extraloader' mechanism to load extension's 'colortable'. color.loadcolortable

color: move hgext.color._styles to mercurial.color.style This is small first step to start moving the color infrastructure into core. The current code of the color extensions is full of strange and debatable things, we'll clean it up in the process as having things into core help the cleaning. Moving _style was the simplest sensible move that is possible. It will also help cleaning up the extension setup process in a later changesets.

color: drop use of the 'global' keyword for '_style' Using 'global' is usually a bad sign. Here it is used so that one can empty the content of a dict at the global scope. We '_style.clear()' and drop the global.

color: drop use of the 'global' keyword for _terminfo_params Using 'global' is usually a bad sign. Here it is used so that one can empty the content of a dict at the global scope. We '_terminfo_params.clear()' and drop the global.

fsmonitor: fix exception message scraping pywatchman.CommandError formats its error message such that 'unable to resolve root' is not a prefix. This change fixes that by instead just searching for it as a substring.

tests: add magic string to bypass check-commit Allow bypassing test-check-commit runs by specifying '# no-check-commit' in the description. This should be avoided but is useful for upstream imports such as pywatchman which will cause check-code to fail otherwise.

demandimport: do not raise ImportError for unknown item in fromlist This is the behavior of the default __import__() function, which doesn't validate the existence of the fromlist items. Later on, the missing attribute is detected while processing the import statement. https://hg.python.org/cpython/file/v2.7.13/Python/import.c#l2575 The comtypes library relies on this (maybe) undocumented behavior, and we got a bug report to TortoiseHg, sigh. https://bitbucket.org/tortoisehg/thg/issues/4647/ The test added at 26a4e46af2bc verifies the behavior of the import statement, so this patch only adds the test of __import__() function and works around CPython/PyPy difference.

convert: config option for git rename limit By default, Git applies rename and copy detection to 400 files. The diff.renamelimit config option and -l argument to diff commands can override this. As part of converting some repositories in the wild, I was hitting the default limit. Unfortunately, the warnings that Git prints in this scenario are swallowed because the process running functionality in common.py redirects stderr to /dev/null by default. This seems like a bug, but a bug for another day. This commit establishes a config option to send the rename limit through to `git diff-tree`. The added tests demonstrate a too-low rename limit doesn't result in copy metadata being recorded.

chgserver: override runcommand Next patches will customize chgserver's runcommand. So let's override it. The docstring is temporarily missing and will be filled later.

chgserver: store csystem separately Previously, the "system" channel is inside the ui object. In the future, chg will let dispatch to create a new ui object from scratch, to maximize compatibility. And chgserver will use a "uisetup" like an extension to wrap ui.system. To be able to do that cleanly, the system channel needs to be accessed directly.

py3: replace sys.platform with pycompat.sysplatform (part 2 of 2)

py3: replace sys.platform with pycompat.sysplatform (part 1 of 2) sys.platform returns unicode on python 3 world. Our code base has most of the things bytes because of the transformer. So we have a bytes version of this as pycompat.sysplatform. This series of 2 patches replaces occurences of sys.platform with pycompat.sysplatform.

py3: replace os.name with pycompat.osname (part 2 of 2)

py3: replace os.name with pycompat.osname (part 1 of 2) os.name returns unicodes on py3 and we have pycompat.osname which returns bytes. This series of 2 patches will change every ocurrence of os.name with pycompat.osname.
