bundle2: don't try to recover from a GeneratorExit (issue4785) GeneratorExit means the other end of the conversation has already stopped listening, so don't try and yield out error information. Instead, just let the GeneratorExit propagate normally. This should resolve esoteric issues observed with servers that have aggressive timeouts waiting for data to send to clients logging internal Python errors[0]. This has been observed with both gunicorn's gevent worker model and with scm-manager's built-in webserver (which itself is something sitting inside jetty.) 0: Exception RuntimeError: 'generator ignored GeneratorExit' in <generator object getchunks at 0x7fd2f6c586e0> ignored

revset: fix resolving strings from a list When using multiple revsets that get optimized into a list (like hg log -r r1235 -r r1237 in hgsubversion), the revset list code was assuming the strings were resolvable via repo[X]. hgsubversion and other extensions override def stringset() to allow processing different revision identifiers (such as r1235 or g<githash>), and there for the _list() implementation was circumventing that resolution. The fix is to just call stringset(). The default implementaiton does the same thing that _list was already doing (namely repo[X]). This has always been broken, but it was recently exposed by 4ee4f7415095 which made "--rev X --rev Y" produce a combined revset "X | Y".
