encoding: extend test cases for utf8b This adds a round-trip helper and a few tests of streams that could cause synchronization problems in the encoder.

merge: make 'cd' and 'dc' actions store the same arguments as 'm' We're going to treat these conflicts similarly to merge conflicts, and this change to the way we store things in memory makes future code a lot simpler.

merge: stop emptying out 'cd' and 'dc' actions (1) These aren't currently read from anywhere, so emptying this out is pointless. (2) These *will* be read from later in upcoming patches, and not emptying them out will be important then.

rebase: add returning value from pullrebase function So far pullrebase function has always returned None value, no matter what orig function returned. This behaviour made impossible for pull to change returned value from mercurial process (it has always ended with 0 value by default). This patch makes pullrebase returning with returned value from orig.

resolve: restore .orig only after merge is fully complete (issue4952) Previously, we'd restore the .orig file after the premerge is complete but before the merge was complete. This would lead to the .orig file potentially containing merge conflict markers in it, as a leftover from the last merge attempt.

monoblue: add a space to separate navigation links in file log footer Before: '(0)-60tip', after: '(0) -60 tip'.

merge: move messages about possible conflicts a litte earlier I actually wanted to reduce the amount of code around the call to applyupdates(), so I tried moving these warnings a little earlier, and I think it makes the output make a little more sense (see changes to test cases).

import-checker: include lineno in warning message This makes it easy to look for imports in function scope.

import-checker: extract function to generate a formatted warning This is the stub to embed lineno. See the next patch for details.

import-checker: make it executable for convenience

test-fileset: glob the updated file count for Windows stability Some of the prior changes are platform dependent, involving symlinks, exec bits and non portable names. An update 10 lines above also globbed this value to avoid differences, since this line isn't of particular interest- the filesets are.

tests: tolerate differences between Linux and Windows error strings These are related to differences in how missing files and network connection failures are displayed. I opted to combine the strings in one line instead of using '#if windows' blocks around entire commands in order to avoid future changes being accidentally missed in the Windows sections. Globbing away the entire output seemed wrong, as it could mask other failures. The raw messages involved are: Linux Windows "* not known" <-> "getaddrinfo failed" "Connection refused" <-> "No connection could be made because the target machine actively refused it" "No such file or directory" <-> "The system cannot find the file specified" Issue 4941 indicates that NetBSD has yet another string for "* not known". Also, the histedit test shows that the missing file is printed first on Windows, last on Linux. That is controlled in windows.py:posixfile if we care to change it.
