test-check-shbang: work around check-code not wanting hardcoded paths I'm about to fix a bug in check-code that a # anywhere on a line treated the rest of the line as a comment, even if it was meaningful. This test is the one place we explicitly *do* want hardcoded paths referenced, but we can work around that by specifying bin as a regular expression.

tests: relax "Connection refused" match We already had the match relaxed on Windows, but on Google Compute Engine VMs I'm seeing "Network is unreachable" instead of "Connection refused". At this point, just give up and make sure we get an error back.

commandserver: backport handling of forking server from chgserver This is common between chg and vanilla forking server, so move it to commandserver and unify handle(). It would be debatable whether we really need gc.collect() or not, but that is beyond the scope of this series. Maybe we can remove gc.collect() once all resource deallocations are switched to context manager.

commandserver: promote .cleanup() hook from chgserver This allows us to unify _requesthandler.handle().

commandserver: extract method to create commandserver instance per request This is a step toward merging chgserver._requesthandler with commandserver's.

error: make hintable exceptions reject unknown keyword arguments (API) Previously they would accept any typos of the hint keyword.

error: make HintException a mix-in class not derived from BaseException (API) HintException is unrelated to the hierarchy of errors. It is an implementation detail whether a class inherits from HintException or not, a sort of "private inheritance" in C++. New Hint isn't an exception class, which prevents catching error by its type: try: dosomething() except error.Hint: pass Unfortunately, this passes on PyPy 5.3.1, but not on Python 2, and raises more detailed TypeError on Python 3.

sslutil: move context options flags to _hostsettings Again, moving configuration determination to a single location.

sslutil: move protocol determination to _hostsettings Most of the logic for configuring TLS is now in this function. Let's move protocol determination code there as well.

share: don't recreate the source repo each time Previously, every time you asked for the source repo of a shared working copy it would recreate the repo object, which required calling reposetup. With certain extension enabled, this can be quite expensive, and it can happen many times (for instance, share attaches a post transaction hook to update bookmarks that triggers this). The fix is to just cache the repo object instead of constantly recreating it.

setup: prepare for future cffi modules by adding placeholder in setup

journal: add support for seaching by pattern If a pattern is used, include the entry name in the output, to make it clear what name was matched.

journal: add share extension support Rather than put everything into one journal file, split entries up in *shared* and *local* entries. Working copy changes are local to a specific working copy, so should remain local only. Other entries are shared with the source if so configured when the share was created. When unsharing, any shared journale entries are copied across.

journal: add dirstate tracking Note that now the default action for `hg journal` is to list the working copy history, not all bookmarks. In its place is the `--all` switch which lists all name changes recorded, including the name for which the change was recorded on each line. Locking is switched to using a dedicated lock to avoid issues with the dirstate being written during wlock unlocking (you can't re-lock during that process).
