hgweb: expose list of per-repo labels to templates hgweb currently offers limited functionality for "classifying" repositories. This patch aims to change that. The web.labels config option list is introduced. Its values are exposed to the "index" and "summary" templates. Custom templates can use template features like ifcontains() to e.g. look for the presence of a specific label and engage specific behavior. For example, a site operator may wish to assign a "defunct" label to a repository so the repository is prominently marked as dead in repository indexes.

histedit: move autoverb rule to the commit it matches Inspired by how 'git rebase -i' works, we move the autoverb to the commit line summary that it matches. We do this by iterating over all rules and inserting each non-autoverb line into a key in an ordered dictionary. If we find an autoverb line later, we then search for the matching key and append it to the list (which is the value of each key in the dictionary). If we can't find a previous line to move to, then we leave the rule in the same spot. Tests have been updated but the diff looks a little messy because we need to change one of the summary lines so that it will actually move to a new spot. On top of that, we added -q flags to future some of the output and needed to change the file it modified so that it wouldn't cause a conflict.

histedit: use _getsummary in ruleeditor This patch uses our common method instead of duplicating logic.

histedit: use _getsummary in torule This patch uses our common method instead of duplicating logic.

histedit: extract common summary code into method We're going to need to use this code in our autoverb logic so let's extract it now and save ourselves from code duplication.

histedit: remove unneeded initial parameter Now that the autoverb logic no longer acts on an individual rule line, we don't need this parameter since we apply our logic just once at the time of initialization.

histedit: move autoverb logic from torule to ruleeditor This is needed for an upcoming change that will automatically rearrange the rules based on the commit message. Before this patch, the autoverb logic only applied to one rule at a time. This moves that logic one step up so that it can iterate over all the rules and rearrange as needed.

treemanifests: actually strip directory manifests Stripping has only partly worked since 7cbb3a01fa38 (repair: use cg3 for treemanifests, 2016-01-19): the bundle seems to have been created correctly, but revlog entries in subdirectory revlogs were not stripped. This meant that e.g. "hg verify" would fail after stripping in a tree manifest repo. To find the revisions to strip, we simply iterate over all directories in the repo (included in store.datafiles()). This is inefficient for stripping few commits, but efficient for stripping many commits. To optimize for stripping few commits, we could instead walk the tree from the root and find modified subdirectories, just like we do in the changegroup code. I'm leaving that for another day.

logtoprocess: do not leak the ui object in uisetup logtoprocess.log should use "self" passed in function arguments instead of the "ui" object from outside the function.

chgserver: document why we don't merge mtimehash and confighash People may get confused about chg's mtimehash and confighash design: why two hashes instead of just one. This patch adds text addressing the concern.
