subrepo: reset 'self.ui' to the subrepo copy of 'ui' in the hgsubrepo class Creation of the subrepo's '_repo' object creates a new 'ui' by combining the parent repo's 'baseui' and reading in the subrepo's hgrc file. This simply avoids 'self.ui' and 'self._repo.ui' pointing to different objects, which seems like a potential source of bugs. Git and Svn subrepos are unchanged, because they don't have their own ui, and have always used their parent's for their configuration.

subrepo: rename the '_ui' member to 'ui' The localrepository class has a 'ui' member, so keeping the names the same will allow for duck typing with subrepo instances when accessing 'ui'. Changing this is easier than finding all of the localrepository instance uses and renaming that to '_ui'.

subrepo: drop the '_ui' member in the subrepo subclasses This member has existed in the base class since fcbc66b5da6a.

graphmod: attempt to clarify documentation of groupbranchiter() Thanks to Pierre-Yves for checking my cleanups here and helping me understand the algorithm well enough to help document it.

graphmod: rename graph-topological config to graph-group-branches The latter suggests what the change is slightly better.

groupbranchiter: allow callers to select the first branch Instead of just bootstrapping the algorithm with the first revision we see, allow callers to pass revs that should be displayed first. All branches are retained until we can display such revision. Expected usage is to display the current working copy parent first.

groupbranchiter: support for non-contiguous revsets The algorithm now works when some revisions are skipped. We now use "first included ancestors" instead of just "parent" to link changesets with each other.

groubranchhiter: indent most of the inner code We are going to add an additional layer of indentation to support non-contiguous revset. We do it in a pure code movement changeset to help the readability of the next changeset.

graphlog: add a way to test the 'groupbranchiter' function We add an experimental config option to use the topological sorting. I first tried to hook the 'groupbranchiter' function in the 'sort' revset but this was useless because graphlog enforces revision number sorting :( As the goal is to advance on the topological iteration logic, I see this experimental option as a good way to move forward. We have to use turn the iterator into a list because the graphlog is apparently not ready for pure iterator input yet.

graphmod: add a function for topological iteration This changeset introduces a function to perform topological (one branch after the other) iteration over a set of changesets. This first version has a lot of limitations, but the approach should be flexible enough to allow many improvements in the future. This changeset aims to set the first stone more than providing a complete solution. The algorithm does not need to know the whole set of nodes involved before emitting revision. This makes it a good candidate for usage in place like `hg log` or graphical tools that need a fast first result time.

namespaces: add branches Note that the exception-catching from the previous branchtip check is moved up to catch exceptions from the try block surrounding the namespace lookup.

namespaces: add tags

namespaces: remove weakref; always pass in repo It turns out that maintaining a reference of any sort (even weak!) to the repo when constructed doesn't work because we may at some point pass in a repoview filtered by something other than what the initial repo was.

changectx: use names api to simplify and extend node lookup Previously, changectx had to know about each type of name (bookmark, tag, etc.) to look up. Now, we use repo.namenodes to simplify (and extend) this.

namespaces: add a method to the first matching node for a given name

namespaces: add bookmarks to the names data structure This marks the first use of abstracting our different types of named objects (bookmarks, tags, branches, etc.) and upcoming patches will use this to simplify logic.

namespaces: add a convenience property for the weakref _repo

namespaces: pass repo to __init__ We store repo as a weakref so that we can prevent a cycle between namespaces and localrepo.

namespaces: add a function to turn single results into lists

namespaces: add a method to register new namespaces

namespaces: introduce a generic way to map between names and nodes This patch begins the work to provide a way to register a namespace to handle 'names'. Benefits of this would be, - improved templating: This would provide {name} which could output any branch, bookmark, tag, or any extension registered namespace all without having the extension doing any extra work - improved tab completion: Since this provides a single source of all 'names', tab completion would not need to know of each namespace - changeset lookup: Similar to before, a unified place to get all 'names' will allow finding changesets without any extension code having to reimplement this Also, d226fe36e362 has shown us that for internal code which expects a certain type of method or behavior, we should provide an easy way for extensions to check this behavior.

statichttprepo: update profile of __call__ in mock vfs object New code paths could fail because the old statichttprepo profile couldn't handle the usual parameters. Instead, reuse a more generic profile also used in readonlyvfs.

tests: avoid git diffstat singular/plural output difference 'git diff --stat' output changed with regard to the amount of changes/insertions/deletions shown. In older git versions (1.7.7.6), output was shown as: 2 files changed, 2 insertions(+), 1 deletions(-) In newer versions, output is shown as: 2 files changed, 2 insertions(+), 1 deletion(-) This patch uses a regex to handle both cases.

subrepo: add revert support without backup for git subrepos Previously, git subrepos did not support reverting. This change adds basic support for reverting when '--no-backup' is specified. A warning is given (and the current state is kept) when a revert is done without the '--no-backup' flag.

match: make 'always' and 'exact' functions, not classes There is no reason for classes 'always' and 'exact' not to be just functions that return instances the plain 'match' class.

share: implement shared bookmark functionality This does not cause any behavioral change unless a 'bookmarks.shared' marker file exists. A future change will add UI to create this file when a repository is shared.

debugindex: respect --debug flag to show full nodeids

localrepo.clone: add a way to override server preferuncompressed Without this patch, if the server sets preferuncompressed, there's no way for clients to override that and force a non-streaming clone. With this patch, we extend the meaning of --pull to also override preferuncompressed and force a non-streaming clone.
