format: introduce 'format.usegeneraldelta` This option will make repositories created as general delta by default but will not make Mercurial aggressively recompute deltas for all incoming bundle. Instead, the delta contained in the bundle will be used. This will allow us to start having general delta repositories created everywhere without triggering massive recomputation costs for all new clients cloning from old servers.

scmutil: extract general delta config handling in a function General delta is currently controlled by a single option, we will introduce a new one in the next changeset. We extract the logic in a function while it is simple.

test: test-bundle-type.t needs to work more universally The cut and head utilities on Solaris have weird differences from the GNU versions. The f helper script does a dump more nicely than those tools, anyway.

bash_completion: add -p|--patch|--stat support for shelve

test-convert-git: silence commit output for stablity When running the tests with 1.7.7.6, I get 'files' and 'insertions' instead of the singular forms, and there is also an additional '0 deletions(-)' at the end. Since this doesn't seem important to the test, silence it.

rebase: preserve the 'intermediate-source' attribute of grafts Preserving the 'source' attribute of grafts started with a69a77a80900, which predates the introduction of 'intermediate-source' in 51930a7180bd by a year and a half. It looks like not preserving this was an oversight. On a related note, notice how the source value of 32af76 is no longer visible in the graph above this test. Is it reasonable to import the sha1 translation from evolve.py:relocate() into scmutil or similar, and use that to fixup these attributes as well as the commit message? (I realize that evolve is still experimental, but I don't see a way to do this from the evolve extension.)

verify: add a hook that can let extensions manipulate file lists Without a hook of this nature, narrowhg[0] clones always result in 'hg verify' reporting terrible damage to the entire repository history. With this hook, we can ignore files that aren't supposed to be in the clone, and then get an accurate report of any damage present (or not) in the repo. 0: https://bitbucket.org/Google/narrowhg

resolve: don't abort when file is missing A file being missing is a completely valid situation in which the user may want to re-resolve merge conflicts. Mercurial already maintains backups of local data, so this turns out to be easy to handle.
