sslutil: capture string string representation of protocol This will be used in a subsequent patch to improve messaging.

sslutil: allow TLS 1.0 when --insecure is used --insecure is our psuedo-supported footgun for disabling connection security. The flag already disables CA verification. I think allowing the use of TLS 1.0 when specified is appropriate.

hg: copy [hostsecurity] options to remote ui instances (issue5305) TIL that ui instances for remote/peer repos don't automagically inherit config options from .hg/hgrc files. This patch makes remote ui instances inherit options from the [hostsecurity] section. We were already inheriting options from [hostfingerprints] and [auth]. So adding [hostsecurity] to the list seems appropriate.

rbc: fix superfluous rebuilding from scratch - don't abuse self._rbcnamescount The code used self._rbcnamescount as if it was the length of self._names ... but actually it is just the number of good entries on disk. This caused the cache to be populated inefficiently. In some cases very inefficiently. Instead of checking the length before lookup, just try a lookup in self._names - that is also in most cases faster. Comments and debug messages are tweaked to help understanding the issue and the fix.

rbc: test case for incorrect and too aggressive invalidation of invalid caches

util: better handle '-' in version string (issue5302) versiontuple() was previously only splitting on '+' and strings like "3.9-rc" were causing it to misreport the version as (3, None). By splitting on either '+' or '-' we can handle our version strings with "-rc" in them.

convert: update use of deprecated bzrlib property The inventory property was deprecated in favor of root_inventory in bzr 2.5.0. Current version is 2.7.0. I noticed this when testing locally on Python 2.6.9, which has warnings turned on by default. The failure that occurs without this patch can be seen on Python 2.7 by running with warnings enabled: $ PYTHONWARNINGS=::DeprecationWarning make 'test-convert-bzr*'

hghave: fix typo of sslutil.supportedprotocols

rebase: turn rebase revs into set before filtering obsolete When the inhibit extension from mutable-history is enabled, it attempts to iterate over the rebaseset to prevent the nodes being rebased from being marked obsolete. This happens at the same time as rebase's _filterobsoleterevs function trying to iterate over the rebaseset to figure out which ones are obsolete. The two of these iterating over the same revset generatorset cause a 'generator already executing' exception. This is probably a flaw in the revset implementation, since iterating over the same set twice should be supported. This regression was introduced in 5d16ebe7b14, since it changed _filterobsoleterevs to be called before the rebaseset was turned into a set(). For now let’s just make the rebaseset an actual set again before calling that function. This was caught by the inhibit tests.

commandserver: update comment about setpgid Now setpgid has 2 main purposes: better handling for terminal-generated SIGTSTP, SIGINT, and process-exit-generated SIGHUP. Update the comment to explain things more clearly.
