Added tag 3.8 for changeset f85de28eae32

debian: alphabetize build deps

debian: fix lintian warning about debhelper It seems this is correct but does it work on older distros? I ran the docker-jessie rule and didn't get any warnings.

builddeb: remove chmod as lintian tells us It turns out we just need debian/rules to be executable, so we do just that.

builddeb: use codename in version Apparently, this is needed to allow ppas to be built for multiple distros.

rebase: restrict rebase destination to the pulled set (issue5214) Before this patch, `hg pull --rebase` would be a strict sequence of `hg pull` followed by `hg rebase` if anything was pulled. Now that rebase pick his default destination the same way than merge, than `hg rebase` step would abort in the case the repo already had multiple anonymous heads (because of the ambiguity). (changed in fac3a24be50e) The intend of the user with `hg pull --rebase` is clearly to rebase on pulled content. This used to be (mostly) enforced by the former default destination for rebase, "tipmost changeset of the branch" as the tipmost would likely a changeset that just got pulled. But this intended was no longer enforced with the new defaul destination (unified with merge). This changeset makes use of the '_destspace' mechanism introduced in the previous changeset to enforce this. This partially fixes issue5214 as no change at all have been made to the new handling of the case with bookmark (unified with merge).

destutil: add the ability to specify a search space for rebase destination In the 'hg pull --rebase', we don't want to pick a rebase destination unrelated to the pull, we lay down basic infrastructure to allow such restriction on stable (before 3.8 release) in this case. See issue 5214 for details. Actual usage and test will be in the next patch.

sslutil: restore old behavior not requiring a hostname argument (issue5210) This effectively backs out changeset 1fde84d42f9c. The http library behind ui.http2=true isn't specifying the hostname. It is the day before the expected 3.8 release and we don't want to ship a regression. I'll try to restore this requirement in the 3.9 release cycle as part of planned improvements to Mercurial's SSL/TLS interactions.

tests: test a variety of cache invariants We've historically had a problem maintaining the expected invariants on our caches, especially when introducing new caches. This tests documents the invariants and exercises them across most of our existing cache files.
