statfs: simplify handling of return value Py_BuildValue() can translate NULL pointer to None.

hghave: use util.getfstype

runtests: change local IP glob pattern from "127.0.0.1" to "$LOCALIP" This is similar to what 348b2b9da703 does. Since 636cf3f7620d has changed "127.0.0.1" to "$LOCALIP". The glob pattern needs update accordingly. It is expected to fix tests running in some BSD jails.

tags: deprecated 'repo.tag' All user are gone. We can now celebrate the removal of some extra line from the 'localrepo' class.

drawdag: use 'tagsmod.tag' instead of 'repo.tag' The former is about to be deprecated.

tags: use the 'tag' function from the 'tags' module in the 'tag' command There is No need to go through the 'repo' object method anymore.

tags: move 'repo.tag' in the 'tags' module Similar logic, pretty much nobody use this method (that creates a tag) so we move it into the 'tags' module were it belong.

tags: move '_tags' from 'repo' to 'tags' module As far as I understand, that function do not needs to be on the local repository class, so we extract it in the 'tags' module were it will be nice and comfortable. We keep the '_' in the name since its only user will follow in the next changeset.

hgweb: filter diff hunks when 'linerange' and 'patch' are specified in filelog

hgweb: add a 'linerange' parameter to webutil.diffs() This is used to filter out hunks based on their range (with respect to 'node2' for patch.diffhunks() call, i.e. 'ctx' for webutil.diffs()). This is the simplest way to filter diff hunks, here done on server side. Later on, it might be interesting to perform this filtering on client side and expose a "toggle" action to alternate between full and filtered diff.

hgweb: handle a "linerange" request parameter in filelog command We now handle a "linerange" URL query parameter to filter filelog using a logic similar to followlines() revset. The URL syntax is: log/<rev>/<file>?linerange=<fromline>:<toline> As a result, filelog entries only consists of revision changing specified line range. The linerange information is propagated to "more"/"less" navigation links but not to numeric navigation links as this would apparently require a dedicated "revnav" class. Only update the "paper" template in this patch.

shelve: add logic to preserve active bookmarks This adds an explicit active-bookmark-handling logic to shelve. Traditional shelve handles it by transaction aborts, but it is a bit ugly and having an explicit functionality seems better.

metadataonlyctx: speed up sanity check Previously the sanity check will construct manifestctx for both p1 and p2. But it only needs the "manifest node" information, which could be read from changelog directly.

revset: factor out linerange processing into a utility function Similar processing will be done in hgweb.webutil in forthcoming changeset.

hgweb: add a "patch" query parameter to filelog command Add support for a "patch" query parameter in filelog web command similar to --patch option of `hg log` to display the diff of each changeset in the table of revisions. The diff text is displayed in a dedicated row of the table that follows the existing one for each entry and spans over all columns. Only update "paper" template in this patch.
