convert: remove unused newnames variable in filemap

push: fix bug in detection of remote obsolete support Current code check obsolete availability in local repo.

incoming/outgoing: handle --graph in core

log: support --graph without graphlog extension The glog command is preserved in the extension for backward compatibility.

graphlog: extract revset/support functions into cmdutil

graphlog: extract ascii drawing code into graphmod

patchbomb: rewrite getoutgoing() with revsets Another version could have returned a revset expression from getoutgoing(), but we do not know how many times it will be resolved, so better do it once explicitely.

patchbomb: support --outgoing and revsets With --outgoing, input revisions were passed to getoutgoing() before being resolved.

patchbomb: make --outgoing ignore secret changesets getoutgoing() is just rewritten almost like revset.outgoing(), a follow-up will make it use revsets after the tests are adjusted.

merge with stable

convert: make filemap renames consistently override revision renames When the source repository had a revision renaming "$new -> $old", but the filemap a "$old -> $new" rename, the converted revision could use either $new (deleting the file) or $old (keeping the file) when getting the file data, depending on the lexicographical order of those names. So the resulting revision would leave some files untouched (as expected), but delete others arbitrarely.

obsolete: compute extinct changesets `extinct` changesets are obsolete changesets with obsolete descendants only. They are of no interest anymore and can be: - exclude from exchange - hidden to the user in most situation - safely garbage collected This changeset just allows mercurial to detect them. The implementation is a bit naive, as for unstable changesets. We better use a simple revset query and a cache, but simple version comes first.

push: refuse to push unstable changesets without force User should resolve unstability locally before pushing the same way we encourage user to merge locally instead of pushing a new remote head. If we are to push obsolete changeset, at least one set of the pushed set will be either obsolete or unstable. The check is narrowed to only heads.

obsolete: compute unstable changeset An unstable changeset is a changeset *not* obsolete but with some obsolete ancestors. The current logic to decide if a changeset is unstable is naive and very inefficient. A better solution is to compute the set of unstable changeset with a simple revset and to cache the result. But this require cache invalidation logic. Simpler version goes first.

revset: add an `obsolete` symbol This predicate matches obsolete changesets. This is a naive implementation to be improved later.

push: refuse to push obsolete changesets This is a first version. Simple but not very efficient. Note that this changeset introduce the "obsolete" word in the UI.

push: accept revset argument for --rev

check-code: recognise %= as an operator

tests: do exclude what is expected

parsers.c: remove warning: 'size' may be used uninitialized in this function Some compilers / compiler options (such as gcc 4.7) would emit warnings: mercurial/parsers.c: In function 'pack_dirstate': mercurial/parsers.c:306:18: warning: 'size' may be used uninitialized in this function [-Wmaybe-uninitialized] mercurial/parsers.c:306:12: warning: 'mode' may be used uninitialized in this function [-Wmaybe-uninitialized] It is apparently not smart enough to figure out how the 'err' arithmetics makes sure that it can't happen. 'err' is now replaced with simple checks and goto. That might also help the optimizer when it is inlining getintat().

graphlog: remove unused ASCIIDATA constant It was introduced by d9acbe7b0049, returned by asciiformat() but never read anywhere. 20140c249e63 stopped using it completely, and the graphmod.CHANGESET type is passed through all functions.

graphlog: make functions private, fix names

graphlog: remove unused get_revs() function

localrepo: use file API via vfs while ensuring repository directory As a part of migration to vfs, this patch invokes some file API indirectly via vfs, while ensuring repository directory in the constructor of "localrepository" class. New file API are added to "scmutil.abstractopener" class, because they are also used via other derived classes than "scmutil.opener". But "join()" is not yet defined other than "scmutil.opener" class, because it should not be used via other opener classes yet.

localrepo: use "vfs" intead of "opener" while ensuring repository directory As a part of migration to vfs, this patch uses "self.vfs" instead of "self.opener", while ensuring repository directory in the constructor of "localrepository" class.

localrepo: use the path relative to "self.vfs" instead of "path" argument As a part of migration to vfs, this patch uses "self.root", which can be recognized as the path relative to "self.vfs", instead of "path" argument. This fix allows to make invocations of "util.makedirs()" and "os.path.exists()" while ensuring repository directory in "localrepository.__init__()" ones indirectly via vfs. But this fix also raises issue 2528: "hg clone" with empty destination. "path" argument is empty in many cases, so this issue can't be fixed in the view of "localrepository.__init__()". Before this patch, it is fixed by empty-ness check ("not name") of exception handler in "util.makedirs()". try: os.mkdir(name) except OSError, err: if err.errno == errno.EEXIST: return if err.errno != errno.ENOENT or not name: raise This requires "localrepository.__init__()" to invoke "util.makedirs()" with "path" instead of "self.root", because empty "path" is treated as "current directory" and "self.root" becomes valid path. But "hg clone" with empty destination can be detected also in "hg.clone()" before "localrepository.__init__()" invocation, so this patch re-fixes issue2528 by checking it in "hg.clone()".

localrepo: use "self.wvfs.join()" instead of "os.path.join()" As a part of migration to vfs, this patch uses "self.wvfs.join()" instead of "os.path.join()", while initialization of fields in the constructor of "localrepository" class.

localrepo: use path expansion API via vfs As a part of migration to vfs, this patch moves path expansion API invocations in the constructor of "localrepository" to the constructor of "opener", because the root path to the repository is very important to handle paths using non-ASCII characters correctly. This patch also rearrange initialization order of "wvfs" field, because it is required to initialize "self.root".

localrepo: add "vfs" fields to "localrepository" for migration from "opener" As a part of migration to vfs, this patch adds "vfs" fields to "localrepository" class. This allows new codes to access current "opener" objects related to repositories via "vfs" fields, so patches referring to "vfs" will replace referring to "opener" in time. This patch also adds initializations for "vfs" fields to "statichttprepository" class derived from it, because its constructor doesn't invoke the constructor of "localrepository", so "vfs" fields should be initialized explicitly as same as "opener" fields: it has no working directory, so "wvfs" field is not added.

largefiles: optimize status by synchronizing lfdirstate with the largefile on update This speeds up status on a largefiles repo by synchronizing the largefiles dirstate to the largefile's mtime upon update, preventing the files from coming back as "unsure" later, requiring a check of the SHA1 sum.

store: abstract out how we retrieve a file's size

mq: check subrepo synchronizations against parent of workdir or other appropriate context Before this patch, MQ checks each subrepo synchronizations against the working directory context, so ".hgsubstate" updating is not imported into MQ revision correctly in cases below: - qrefresh when current ".hgsubstate" is already synchronized with each subrepos: you can reproduce this easily by just twice or more qrefresh invocations - qnew just after rollback of commit which updates ".hgsubstate" This patch resolves this by checking subrepo states against: - the parent of "qtop" for qrefresh, or - the parent of working context otherwise
