revset: introduce new operator "##" to concatenate strings/symbols at runtime Before this patch, there is no way to concatenate strings at runtime. For example, to search for the issue ID "1234" in descriptions against all of "issue 1234", "issue:1234", issue1234" and "bug(1234)" patterns, the revset below should be written fully from scratch for each issue ID. grep(r"\bissue[ :]?1234\b|\bbug$1234$") This patch introduces new infix operator "##" to concatenate strings/symbols at runtime. Operator symbol "##" comes from the same one of C pre-processor. This concatenation allows parametrizing a part of strings in revset queries. In the case of example above, the definition of the revset alias using operator "##" below can search issue ID "1234" in complicated patterns by "issue(1234)" simply: issue($1) = grep(r"\bissue[ :]?" ## $1 ## r"\b|\bbug$" ## $1 ## r"$") "##" operator does: - concatenate not only strings but also symbols into the string Exact distinction between strings and symbols seems not to be convenience, because it is tiresome for users (and "revset.getstring" treats both similarly) For example of revset alias "issue()", "issue(1234)" is easier than "issue('1234')". - have higher priority than any other prefix, infix and postfix operators (like as "##" of C pre-processor) This patch (re-)assigns the priority 20 to "##", and 21 to "(", because priority 19 is already assigned to "-" as prefix "negate".

largefiles: pass a matcher instead of a raw file list to removelargefiles() This is consistent with addlargefiles(), and will make it easier to get the paths that are printed correct when recursing into subrepos or invoking from outside the repository. It also now restricts the path that the addremove is performed on if a path is given, as is done with normal files. The repo.status() call needs to exclude clean files when performing an addremove, because the addremove override method calling this used to pass the list of files to delete, which caused the matcher to only consider those files in building the status list. Now the matcher is restricted only to the extent that the caller requested- usually directories if at all. There's no reason for addremove to care about clean files anyway- we don't want them deleted.

hgweb: allow viewing diffs against p1 or p2 for merge commits (issue3904) This adds UI portion of the feature that has resided in mercurial since 2012. Back then the interface was added together with the code, but was shortly backed out because it was deemed "not ready". Code, however, stayed. For the original feature and its implementation, see issue2810 and d605a82cf189. In short, the backed-out interface had two outstanding issues: 1. it was introducing an entirely new term (baseline) and 2. it was present on every changeset's page, even for changesets with 1 parent (or no parents), which didn't make sense This patch implements a hopefully better interface because: 1. it uses the usual terms (diff) and 2. it only shows up when there actually are 2 parents.

namespaces: remove templatename method on the namespaces object Now that there is an object for each individual namespace, we use the templatename property on that object instead of the method on the collection of namespaces.

namespaces: remove names method on the namespaces object Now that there is an object for each individual namespace, we use that instead of the method on the collection of namespaces.

templatekw: update namespace calls Previous patches changed the namespace api to be more of an object-oriented approach. This patch updates the template function to use said api changes.

namespaces: add __getitem__ property Since the namespaces object uses an underlying (sorted) dictionary to store the namespaces, it makes sense to expose this to naturally gain access to those namespaces.

cmdutil.jsonchangeset: properly compute added and removed files jsonchangeset._show() was computing the reverse status of the current changeset. As a result, added files were showing up as removed and removed files were showing up as adds. There were existing tests for this code and they were flat out wrong.
