revset: fix infinite alias expansion detection The alias expansion code it changed from: 1- Get replacement tree 2- Substitute arguments in the replacement tree 3- Expand the replacement tree again into: 1- Get the replacement tree 2- Expand the replacement tree 3- Expand the arguments 4- Substitute the expanded arguments in the replacement tree and fixes cases like: [revsetalias] level1($1, $2) = $1 or $2 level2($1, $2) = level1($2, $1) $ hg log -r "level2(level1(1, 2), 3)" where the original version incorrectly aborted on infinite expansion error, because it was confusing the expanded aliases with their arguments.

revset: explicitely tag alias arguments for expansion The current revset alias expansion code works like: 1- Get the replacement tree 2- Substitute the variables in the replacement tree 3- Expand the replacement tree It makes it easy to substitute alias arguments because the placeholders are always replaced before the updated replacement tree is expanded again. Unfortunately, to fix other alias expansion issues, we need to reorder the sequence and delay the argument substitution. To solve this, a new "virtual" construct called _aliasarg() is introduced and injected when parsing the aliases definitions. Only _aliasarg() will be substituted in the argument expansion phase instead of all regular matching string. We also check user inputs do not contain unexpected _aliasarg() instances to avoid argument injections.

revlog: don't handle long for revision matching The underlying C code doesn't support indexing by longs, there are no legitimate reasons to use a long, and longs should generally be converted to ints at a higher level by context's constructor.

subrepo: make subrepo.subrepo(<not a subrepo path>) fail Until now, when calling subrepo.subrepo with a path at which there is no subrepo, a "nullstate" tuple would be returned. However, this is not very useful (the tuple can't really be used for creating a subrepo), so we'd just as soon have the function just fail, and leave it up to the caller to decide what to do. The motivation for doing this now is to simplify the solution for (issue3056).

dispatch: try and identify third-party extensions as sources of tracebacks Extension authors should explicitly declare their supported hg versions and include a buglink attribute in their extension. In the event that a traceback occurs, we'll identify the least-recently-tested extensionas the most likely source of the defect and suggest the user disable that extension. Packagers should make every effort to ship hg versions from exact tags, or with as few modifications as possible so that the versioning can work appropriately.

hgext: mark all first-party extensions as such
