test: use bundle2 in test-acl This test makes extensive use of --debug so moving to bundle2 based exchange has a massive impact. We do it early to reduce the noise create by a future usage of bundle2 as the default protocol.

test: use both bundle formats in test-pull-http It is valuable to have both formats tested.

test: use bundle2 in test-http-proxy The proxy test does not care about what protocol is used, but the new protocol implies different traffic (and therefore different log output). We switch it to bundle2 early to minimise the noise of using bundle2 for exchange by default.

tests: use bundle2 for test-hook Using bundle2 has an effect on which hooks are run when. We turn it on for test-hooks early to reduce the noise of switching the default exchange to bundle2.

pull: only prefetch bookmarks when using bundle1 All bundle2 servers now support the 'listkeys' part(1), so we'll always be able to fetch bookmarks data at the same time as the changeset. This should be enough to avoid the one race condition that this bookmark prefetching is trying to work around. It even allows future server to make sure everything is generated from the same "transaction" if they become capable of such. The current code was already overwriting the prefetched value with the one in bundle2 anyway. Note that this is not preventing all race conditions in related to bookmark in 'hg pull' it makes nothing better and nothing worse. Reducing the number of listkeys calls will reduce the latency on pull. The pre-fetch is also moved into a discovery step because it seems to belong there. (1) Because all servers not speaking 'pushkey' parts are compatible with the 'HG2X' protocol only.

pull: document the race condition with bookmark name It seems valuable to document this in-place to help the next poor soul looking at this code to understand what kind of beast he is currently facing.

pull: only list remote bookmarks if -B is used to populate pulled heads Listing remote bookmarks results in network traffic and latency. This should be avoided when possible.

hg: explicitly check that peer lookup object has instance() if call failed If a "thing" is callable but raises TypeError for some reason, a callable object would be returned. Thereafter, unfriendly traceback would be displayed: Traceback (most recent call last): ... File "mercurial/hg.pyc", line 119, in _peerorrepo obj = _peerlookup(path).instance(ui, path, create) AttributeError: 'function' object has no attribute 'instance' Instead, we should show the reason why "thing(path)" didn't work: Traceback (most recent call last): ... File "hggit/__init__.py", line 89, in _local p = urlcls(path).localpath() TypeError: 'NoneType' object is not callable If a "thing" is not callable, it must be a module or an object that implements instance(). If that module didn't have instance(), the error message would be "<unloaded module 'foo'> object is not callable". It doesn't make perfect sense, but it isn't so bad as it can blame which module went wrong.

extensions: show traceback on load failure if --traceback flag is set Before this patch, there was no handy way to investigate the reason why extension couldn't be loaded. If ui.debug is set, tracebacks of both "hgext.foo" and "foo" are displayed because the first ImportError could occur at very deep dependency module.

ui: flush stdout before writing traceback to stderr Sometimes a traceback message is paired with ui.debug(). This patch makes sure that these messages are displayed in the right order.

treemanifest: visit directory 'foo' when given e.g. '-X foo/ba?' For globs like 'foo/ba?', match._roots() will return 'foo'. Since visitdir(), excludes directories in the excluded roots, it would skip the entire foo directory. This is incorrect, since 'foo/ba?' doesn't mean that everything in foo/ should be exluded. Note that visitdir() is called only from the treemanifest class, so this only affects tree manifests. Fix by adding roots to the set of excluded roots only if there are no excluded patterns. Since 'glob' is the default pattern type for globs, we also need to update some -X patterns in the tests to be of 'path' type to take advantage of the visitdir tricks. For consistency, also update the -I patterns. It seems a little unfortunate that 'foo' in 'hg files -X foo' is considered a pattern because of the implied 'glob' type, but improving that is left for another day.
