cmdutil: use a small initial window with --limit In a large repo, running a command like "log -l1 -p" was expensive because it would always traverse 8 commits, as 8 was the initial window size. We now choose the lesser of 8 or the limit, speeding up the "log -l1 -p" case by a factor of 5.

worker: handle worker failures more aggressively We now wait for worker processes in a separate thread, so that we can spot failures in a timely way, wihout waiting for the progress pipe to drain. If a worker fails, we recover the pre-parallel-update behaviour of failing early by killing its peers before propagating the failure.

worker: fix a race in SIGINT handling This is almost impossible to trigger due to the tiny time window involved.

worker: on error, exit similarly to the first failing worker Previously, if a worker failed, we exited with status 1. We now exit with the correct exit code (killing ourselves if necessary).

largefiles: don't cache largefiles for pulled heads by default After discussion, we've agreed that largefiles for newly pulled heads should not be cached by default. The use case for this is using largefiles repos with multiple remote servers (and therefore multiple remote largefiles caches), where users will be pulling from non-default locations on a regular basis. We think this use case will be significantly less common than the use case where all largefiles are stored on the same central server, so the default should be no caching. The old behavior can be obtained by passing the --cache-largefiles flag to pull.

bundle: treat branches created newly on the local correctly (issue3828) Before this patch, "hg bundle --branch foo other" fails to create bundle file, if specified "foo" branch is created newly on the local repository. "hg bundle" uses "hg.addbranchrevs(repo, other, ...)" to look branch names up, even though other outgoing-like implementation uses "hg.addbranchrevs(repo, repo, ...)". In the former invocation, "other" repository recognizes such branches as unknown, so execution is aborted. This patch uses "hg.addbranchrevs(repo, repo, ..)" in "hg bundle" to bundle revisions on such branches correctly.
