localrepo: isolate requirements determination from side effects In preparation for moving requirements determination to its own function.

localrepo: use local variable for requirements assignment A future patch will refactor requirements determination into a standalone function. To prepare for this, refactor the requirements code to assign to a local variable instead of to self.requirements.

destutil: ensure we offer 'hg update' hint when not at head in all cases In the merge case, we abort if the working copy is not at head, offering to run 'hg update' in the hint instead. In the rebase case, we do not abort in that case. Yet if no rebase destination are found, it still make sense to hint the user about running 'hg update'. So we re-introduce a conditional using this branch in the 'onheadcheck == False' case. This will get used on rebase use this function.

chg: forward umask from client to server This is necessary to make chg test pass on test-inherit-mode.t.

chgserver: add setumask method Before this patch, the server won't inherit umask from the client, which will fail test-inherit-mode.t. This patch provides a way for the client to change umask of the server, similar to chdir and setenv.

chgserver: use _readlist and _readstr Use _readlist and _readstr to make the code shorter.

commandserver: use _readlist Use _readlist introduced in previous commit to make the code shorter.

commandserver: add _readstr and _readlist Reading a string or a list are common operations for commandserver and chgserver. This patch adds _readstr and _readlist to avoid duplication.

extensions: add notloaded method to return extensions failed to load Before this patch, there is no easy way to detect if there are extensions failed to load. While this is okay for most situations, chgserver is designed to preload all extensions specified in config and does need the information. This patch adds extensions.notloaded() to return names of extensions failed to load.

histedit: renaming parts to which _histedit was split I recently broke _histedit into multiple functions, each of which had 'action' in its name. This is a little bit confusing since 'action' is the word for an individual histedit plan item (such as edit or pick). To avoid this confusion, these functions are now renamed to contain 'histedit' as part of their names.

histedit: break _histedit into smaller pieces (add _finishaction) This is a part of a bigger effort to refactor histedit with ultimate goal of understanding it.

automv: switch to specifying the similarity as an integer (0-100) This is consistent with the addremove --similarity option.

automv: do not release lock between marking files and the actual commit

automv: reuse existing scutil._markchanges() function

automv: improve function docstrings

automv: remove test for 'developer mode' The tests no longer use this mode, the test is entirely redundant.

automv: add some context for the tests

automv: simplify retrieving the status The default is to show the status in the current working copy, no need to pass in the parent and working copy context here.

tests: change branches test to work cross platform While it is not easy to make a file 000 on Windows, you can emulate most of the behaviors by replacing the file with a directory.

histedit: change string literals to constants in goal naming This is a part of bigger effort to refactor histedit with ultimate goal of understanding it.

run-tests: add --chg option to install and run tests using chg Because the temporary installation directory is shared between hg and chg, --chg is not allowed if --with-hg option is specified. Also, --chg option does not work on FreeBSD because "make" command is hard-coded. These limitations can be improved later. Almost all tests will fail with chg right now.

run-tests: add --with-chg option to run tests using chg Unlike --with-hg=/path/to/chg, this option allows us to start and clean up command servers in isolated environment. And we can specify the hg command as well as the chg command.

destutil: add more precise error classes for destmerge Having exception classes more precise than 'Abort' will allow us to properly catch "nothing to rebase" situations when we will be using 'destmerge' in rebase.

destutil: allow to disable the "on head check" in destmerge 'hg merge' refuses to pick a default destination if the working copy is not on a head. This is a very sensible default for 'hg merge' but 'hg rebase' should work in this situation. So we introduce a way to disable this check. It will soon be used by rebase.
