largefiles: move protocol conversion into getlfile and make it an iterable Avoid the intermediate limitreader and filechunkiter between getlfile and copyandhash - return the right protocol and put the complexity where it better can be managed.

largefiles: don't close the fd passed to store._getfile

largefiles: remove blecch from lfutil.copyandhash - don't close the passed fd

largefiles: drop lfutil.blockstream - use filechunkiter like everybody else The old chunk size is kept - just to avoid changing it.

largefiles: refactoring - use findfile in localstore._getfile

largefiles: refactoring - return hex from _getfile and copyandhash

largefiles: refactoring - create destination dir in lfutil.link

summary: clear "commonincoming" also if branches are different Before this patch, "commonincoming" calculated by "discovery.findcommonincoming()" is cleared, only if "default" URL without branch part (tail "#branch" of URL) differs from "default-push" URL without branch part. But common revisions in "commonincoming" calculated for a branch doesn't include ones for another branch, even if URLs without branch part are same. The result of "discovery.findcommonoutgoing()" invocation with such "commonincoming" becomes incorrect in some cases. This patch clears "commonincoming", also if branch part of "default" differs from one of "default-push". To avoid redundant looking up: - "ui.expandpath('default')" and "ui.expandpath('default-push', 'default')" are not compared directly, even though they contain branch information, because they are not yet normalized by "hg.parseurl()": tail "/" of path, for example - "commonincoming" is not cleared, if branch isn't specified in "default" URL, because such "commonincoming" contains common revisions for all branches This patch also tests "different path, same branch" pattern to check careless degrading around comparison between source and destination.

summary: make "incoming" information sensitive to branch in URL (issue3830) Before this patch, "incoming" information of "hg summary --remote" is not sensitive to the branch specified in the URL of the destination repository, even though "hg pull"/"hg incoming" are so. Invocation of "discovery.findcommonincoming()" without "heads" argument treats revisions on branches other than the one specified in the URL as incoming ones unexpectedly. This patch looks head revisions, which are already detected by "hg.addbranchrevs()" from URL, up against "other" repository, and invokes "discovery.findcommonincoming()" with list of them as "heads" to limit calculation of incoming revisions.

histedit: make "hg histedit" sensitive to branch in URL Before this patch, "hg histedit" are not sensitive to the branch specified in the URL of the destination repository, even though "hg push"/"hg outgoing" are so: Invocation of "discovery.findcommonoutgoing()" without "onlyheads" argument treats revisions on branches other than the one specified in the URL as outgoing ones unexpectedly. This patch specifies list of head revisions, which are already detected by "hg.addbranchrevs()" from URL and looked up against local repository, as "onlyheads" to "discovery.findcommonoutgoing()" to limit calculation of outgoing revisions.
