revset: make "null" able to appear in internal _list() expression This is the same workaround introduced at e16456831516. Without this patch, "null or x" can't be optimized to _list(null x). Test case will be added by the next patch.

revset: make internal _list() expression remove duplicated revisions This allows us to optimize chained 'or' operations to _list() expression. Unlike _intlist() or _hexlist(), it's difficult to remove duplicates by the caller of _list() because different symbols can point to the same revision. If the caller knows all symbols are unique, that probably means revisions or nodes are known, therefore, _intlist() or _hexlist() should be used instead. So, it makes sense to check duplicates by _list() function. '%ls' is no longer used in core, this won't cause performance regression.

repair: use _hexlist() to build revset expression from binary nodes _hexlist() should be efficient than _list().

listkey: display the size of the listkey payload in a debug message This is a useful information to have in general and we already have debug output related to listkeys. I'm planning to play around with massive amount of phases roots and bookmarks so having this data in debug will be very useful. This already got me to spot that one of the Logilab's review repo is exchanging 65KB of phases data during each exchanges.

ssh: test some no-op pull through ssh with --debug It appears that we are never running any wireprotocol operation with a --debug flag. So we are adding some basic testing into 'test-ssh.t'

subrepo: detect issue3781 case earlier so it apply to bundle2 We are doing some strange special casing of phase push when: - the source is a subrepo - the destination is publishing - some changeset are still draft on the destination In that case we do not push phases information (to publish the draft changesets) because it could break simple cycle of 'clone/pull/push' of subrepos. We have to detect this case earlier to have bundle2 respecting it. We change the test to check the behavior for both bundle1 and bundle2.

bundle2: hide bundle2 stream debug under a config flag The old output is very verbose and unsuitable for general debug level. It is however very useful for debugging bundle2 generation or consumption issues. All this verbose ouput is hidden under a 'devel.bundle2.debug' flag.

bundle2: add generic debug output regarding processed interruption If we are about to hide the detailed debug output, we need some generic debug message to replace it in a concise way.

bundle2: add generic debug output regarding processed part payload If we are about to hide the detailed debug output, we need some generic debug message to replace it in a concise way.

bundle2: add generic debug output regarding processed part If we are about to hide the detailed debug output, we need some generic debug message to replace it.

bundle2: add generic debug output at the end of bundle processing If we are about to hide the detailed debug output, we need some generic debug message to replace it in a concise way.

bundle2: add generic debug output regarding processed bundle If we are about to hide the detailed debug output, we need some generic debug message to replace it in a concise way.

histedit: fix keep during --continue The --keep option was being serialized to the state file, but it wasn't actually being used when running a histedit --continue. This fixes that.

dispatch: disable demandimport for the --debugger option Something in Python 2.7.9 or so broke the --debugger option with ui.debugger = ipdb. I get the traceback below. There is some apparent confusion with demandimport. This should be disabled anyway for the --debugger option. The debugger must be imported right away, before any other dispatch. There's no benefit in delaying the debugger import. This patch uses the demandimport.deactivated() context manager.
