Mercurial: Changelog

setup: show how to set the module policy for imports This is not technically needed, since mercurial.__version__ does not exist as a native module, but, without this style wrappings, if something else had a native flavor, the module loader would get upset. In principle, the `env` object is trying to set HGMODULEPOLICY for children, so, conceptually we should set it for this in-process child.

setup: create a module for the modulepolicy Instead of rewriting __init__ to define the modulepolicy, write out a __modulepolicy__.py file like __version__.py This should work for both system-wide installation and in-place build. Therefore we can avoid relying on two separate modulepolicy rules, '@MODULELOADPOLICY@' and 'mercurial/modulepolicy'.

rebase: turn rebaseskipobsolete on by default Consider the following use case. User has a set of commits he wants to rebase onto some destination. Some of the commits in the set are already rebased and their new versions are now among the ancestors of destination. Traditional rebase behavior would make the rebase and effectively try to apply older versions of these commits on top of newer versions, like this: a` --> b --> a` (where both 'a`' and 'a``' are rebased versions of 'a') This is not desired since 'b' might have made changes to 'a`' which can now result in merge conflicts. We can avoid these merge conflicts since we know that 'a``' is an older version of 'a`', so we don't even need to put it on top of 'b'. Rebaseskipobsolete allows us to do exactly that. Another undesired effect of a pure rebase is that now 'a`' and 'a``' are both successors to 'a' which is a divergence. We don't want that and not rebasing 'a' the second time allows to avoid it. This was not enabled by default initially because we wanted to have some more experience with it. After months of painless usages in multiple places, we are confident enough to turn it on my default.

graphlog: bring back color to node symbol template Follows up 3356bf61fa25. A ui object is required to render labels.

revset: add inspection data to max() and min() functions We are likely to be interested in how these functions build a result set.

revset: add inspection data to limit() and last() functions We are likely to be interested in how these functions calculate a result set.

revset: stub to add extra data to baseset for better inspection We sometimes construct a baseset from filtering result. In that case, a baseset can provide more precise information how it is constructed.

revset: add inspection data to all filter() calls This is useful for debugging revset construction.

revset: add extra data to filteredset for better inspection A filteredset is heavily used, but it cannot provide a printable information how given set is filtered because a condition is an arbitrary callable object. This patch adds an optional "condrepr" object that is used only by repr(). To minimize the maintaining/runtime overhead of "condrepr", its type is overloaded as follows: type example -------- --------------------------------- tuple ('<not %r>', other) str '<branch closed>' callable lambda: '<branch %r>' % sorted(b) object other
