strip: move into core As discussed at the 5.2 sprint, replace strip extension by a core command, debugstrip. Obviously, the extension stays for backwards compatibility. As an implementation note, I moved the strip file as is into core, which is not done elsewhere, AFAIK. I could have inlined it into debugcommands, but that doesn't sound great.

revlog: pass sidedata argument to flagutil.processflagswrite() Bug found through pytype. Differential Revision: https://phab.mercurial-scm.org/D9280

pure: guard against empty blocks If blocks is empty, we append `None` to the returned list, which is incorrect. This subtle issue was caught by pytype, which correctly identified the return value as List[Optional[Tuple]] because of this possibility. Differential Revision: https://phab.mercurial-scm.org/D9279

rust-status: don't bubble up os errors, translate them to bad matches In the rare cases when either the OS/filesystem throws an error on an otherwise valid action, or because a path is not representable on the filesystem, or because of concurrent actions in the filesystem, we want to warn the user about said path instead of bubbling up the error, causing an exception to be raised in the Python layer.

rust-status: properly translate OSError to Python This is probably never going to be called after the next few patches, but we might as well make sure this is done correctly for the future rewrite. Differential Revision: https://phab.mercurial-scm.org/D9319

shelve: clear merge state after partial shelve Differential Revision: https://phab.mercurial-scm.org/D9335

tests: show that interactive shelve can leave the repo with a merge state If part of a file is shelved (as we already do in a test), there will be an unfinished merge state left after `hg shelve` finishes. There should never be a merge conflict and there should never be a reason that the user would like to re-resolve conflicts, so we should clear that state (see next patch).

histedit: disable color while rendering template for use in plan Differential Revision: https://phab.mercurial-scm.org/D9324

split: disable color while rendering template for use in commit message Differential Revision: https://phab.mercurial-scm.org/D9322

tests: show how `hg split` can put color codes in commit template With D9255, I made it so `hg split` respects the `commmand-templates.oneline-summary` config. I don't think I realized that the output I modified was being put in a commit message template. The result was that if you have coloring enabled, you get colors in the commit template. This patch show that. The test is unfortunately pretty verbose (like most other `hg split` tests) and shows a bunch of irrelevant "color codes" (templater labels).

chgserver: backport py3 buffered I/O workarounds from procutil I've recently switched to new machine and I found chg's stdout is fully buffered. Even though chg server is a daemon process, it inherits the environment where the chg client originally forked the server. This means the server's stdout might have been wrapped by LineBufferedWrapper. That's why we need to do wrap/unwrap in both ways. The "if" condition in _restoreio() looks weird, but I'm not willing to clean things up because stdio behavior is fundamentally different between py2 and py3, and py2 support will be dropped anyway.

errors: catch urllib errors specifically instead of using safehasattr() Before this patch, we would catch `IOError` and `OSError` and check if the instance had a `.code` member (indicates `HTTPError`) or a `.reason` member (indicates the more generic `URLError`). It seems to me that can simply catch those exception specifically instead, so that's what this code does. The existing code is from fbe8834923c5 (commands: report http exceptions nicely, 2005-06-17), so I suspect it's just that there was no `urllib2` (where `URLError` lives) back then. The old code mentioned `SSLError` in a comment. The new code does *not* try to catch that. The documentation for `ssl.SSLError` says that it has a `.reason` property, but `python -c 'import ssl; print(dir(ssl.SSLError("foo", Exception("bar"))))` doesn't mention that property on either Python 2 or Python 3 on my system. It also seems that `sslutil` is pretty careful about converting `ssl.SSLError` to `error.Abort`. It also is carefult to not assume that instances of the exception have a `.reason`. So I at least don't want to catch `ssl.SSLError` and handle it the same way as `URLError` because that would likely result in a crash. I also wonder if we don't need to handle it at all (because `sslutil` might handle all the cases). It's now early in the release cycle, so perhaps we can just see how it goes?
