dirstate: add docstring for invalidate This always confuses me, and we already have a docstring on localrepo.invalidatedirstate.

tests: simplify and clarify test-obsolete-bundle-strip.t a little

tests: add missing parens in test-obsolete-bundle-strip.t The "(not ${revs})" was missing parens around ${revs}, so when revs was "A + B", it became "(not A + B)" when actually "(not (A + B))" was intended. Fixing that leads to some more testing of strip. Similarly, the parens were missing in "${revs}::", making it "A + B::" instead of "(A + B)::". Thanks to Yuya for noticing this part. This did not affect any existing tests.

test-clonebundles: conditionalize output for Windows This was the fallout from 9d6031df42c8 (on stable). Now that individual lines can be conditionalized, it seems better to be explicit, rather than mash all of this into one regex. "getaddrinfo failed" was added in 4e566f513fd8 to support Windows.

tests: adjust recent output changes for Windows

killdaemons: close pid file before killing processes With #serve enabled on Windows, I was getting occasional stacktraces like this: Errored test-hgweb-json.t: Traceback (most recent call last): File "./run-tests.py", line 724, in run self.tearDown() File "./run-tests.py", line 805, in tearDown killdaemons(entry) File "./run-tests.py", line 540, in killdaemons logfn=vlog) File "...\tests\killdaemons.py", line 94, in killdaemons os.unlink(pidfile) WindowsError: [Error 32] The process cannot access the file because it is being used by another process: '...\\hgtests.zmpqj3\\child80\\daemon.pids' Adrian suggested using util.posixfile, which works. However, the 'mercurial' package isn't in sys.path when invoking run-tests.py, and it isn't clear that hacking[1] it in is a good thing (especially for test-run-tests.t, which uses an installation in a temp folder). I tried using ProcessMonitor to figure out what the other process is, but that monitoring slows things down to such a degree that the issue doesn't occur. I was ready to blame the virus scanner, but it happens without that too. Looking at the code, I don't see anything that would have the pid file open. But I was able to get through about 20 full test runs without an issue with this minor change, whereas before it was pretty certain to hit this at least once in two or three runs.

win32: drop a py26 daemonizing hack I'm not sure what the referenced hang specifically was, but the whole test suite (with #serve) still runs on python 2.7.13. Aside from no longer prepending "cmd.exe /c", this backs out ca6aa8362f33. I'm trying to track down a rare failure of TerminateProcess() with an access error, and I've seen random extra python processes hanging around after running tests sometimes, so this might help. However, e48cb1c7a902 forces this change. Since the pid object is no longer converted to a string, the cmd.exe pid was being saved instead of the hg pid, and none of the daemons were being killed.

checkheads: simplify the code around obsolescence post-processing The 'discardedheads' return become unused and the relationship between newheads and newhs can be clarified. Our next goal here is to be able to extract the _postprocessobsolete call outside of the loop. We keep returning the 'discardedheads' because we'll start using it again soon in this series.

checkheads: drop now unused filtering of 'unsyncedheads' Now that unsynced heads are no longer in the function inputs or returns, we can simplify the code a bit.

checkheads: clarify that we no longer touch the head unknown locally Since c6cb21ddf74a, heads unknown locally no longer get any post processing from obsolescence markers. We clarify this fact by only feeding the list of locally known new heads to the function. This simplification of the input will help moving that post-processing earlier in the function.

headssummary: ensure all returned lists are sorted This is a simple step that will help to keep a stable output in coming refactoring.

discovery: also use lists for the returns of '_oldheadssummary' The '_headssummary' function is documenting and using list objects in its return. We now use them in _oldheadssummary too for consistency. This does not affect any usages of these values.

test: add a push race case where the updated head is obsoleted This is the mirror of the previously added case. We check the case where the racing-push obsoletes a head while the raced-push updates that same head.

test: add a push race case where obsoleted head is updated We check the case where the raced-push obsoletes a head while the racing-push updates that same head.

keepalive: set buffering=True to do more efficient reads of headers Support for buffering was added to python in d09d6fe31b61, first released with python2.7. Without this, the entirety of the response headers is read byte-by-byte (it does more efficient reads when it gets to the non-header part of the response).

keepalive: pass the correct arguments to HTTPResponse python2.7's httplib.HTTPResponse takes the arguments in the following order: sock, debuglevel, strict, method, buffering This was previously passing them in as positional and skipped strict, so we set strict=method. I'm explicitly setting strict=True now to preserve the previous behavior that has been there since this file was created.

help: update the color documentation for Windows 10 ANSI support It looks like only the initial release of Windows 10 lacked support for this functionality. [1][2] Since that build is no longer supported, I didn't bother getting very specific, to keep the help text less cluttered. [1] https://github.com/symfony/symfony/issues/17499#issuecomment-243481052 [2] https://en.wikipedia.org/wiki/Windows_10_version_history

color: enable ANSI support on Windows 10 This will display color if "color.mode=ansi", and default to 'ansi' if the mode is set to 'auto'. The 'debugcolor' command also reflects this policy. Previously, "color.mode=ansi" on Windows printed jibberish around the normal text. Using ANSI color is better, as it avoids the normal loss of color when the default pager is enabled on Windows. See also issue5570. When the underlying function fails (e.g. when run on older Windows), 'auto' still falls back to 'win32'. Apparently, Microsoft originally had this feature turned on by default, and then made it opt-in[1]. Therefore, not enabling it unconditionally seems safer. Instead, only do it after processing the existing check for support in a Unix-like environment. [1] https://github.com/symfony/symfony/issues/17499#issuecomment-243481052

win32: add a method to enable ANSI color code processing on Windows 10 SetConsoleMode() fails with an invalid parameter error if given this option prior to Windows 10, so indicate that to the caller instead of doing explicit version checks.

merge with stable

export: map wctx.node() to 'ff...' node id (issue5438)

revset: add support for integer and hex wdir identifiers As I said before, partial 'ff...' hash isn't supported yet.

localrepo: map integer and hex wdir identifiers to workingctx changectx.__init__() is slightly modified to take str(wdirrev) as a valid integer revision (and raise WdirUnsupported exception.) Test will be added by the next patch.

revlog: map rev(wdirid) to WdirUnsupported exception This will allow us to map repo["ff..."] to workingctx. _partialmatch() will be updated later. I tried "return wdirrev" in place of raising the exception, but earlier exception seemed better.
