hgweb: generate last change date for an empty atom-bookmarks feed (issue5022) RFC 4287 states that atom feeds must have an <updated> element, so let's add one even when repo doesn't have a single bookmark.

hgweb: sort bookmarks in revlog order of their nodes Changes, branches and tags are already in revlog order on /summary, /branches and /tags, let's now make bookmarks be sorted by the same principle. It's more helpful to show more "recent" bookmarks on top. This will affect /bookmarks page in all styles, including atom, rss and raw, and also /summary page. Bookmarks are sorted using a (revision number, bookmark name) tuple.

hgweb: sort bookmarks early Let's do the same thing that /tags page does. It gets sorted tags and then if it needs the latest only, it just slices the first item from the list. Since it's a slice and not a min(), it doesn't throw an exception if the list is empty. This fixes HTTP 500 error from issue5022.

hgweb: add parents to json-log (issue5074) Entries prepared in webutil.changelistentry() skip showing parents in the trivial case when there's only one parent and it's the previous revision. This doesn't work well for the json-log template, which is supposed to just dump raw data in an easy-to-parse format, so let's provide all parents as another keyword: allparents. Using a lambda function here means that the performance of templates that don't use allparents won't be affected (see 41957e50e109).

revset: make _parsealiasdecl() simply return the original parsed tree It wasn't necessary to reconstruct the same tuple.

revset: inline isvalidfunc(), getfuncname() and getfuncargs() See the previous commit for why. These functions are also trivial.

revset: inline isvalidsymbol() and getsymbol() into _parsealiasdecl() Since I'm going to extract a common alias parser, I want to eliminate dependencies to the revset parsing rules. These functions are trivial, so we can go without them.

revset: remove redundant checks for parsed tree of alias If tree is a tuple, it must have at least one element. Also the length of node tuple is guaranteed by the syntax elements. (e.g. 'func' must have 3 items.) This change will help inlining these trivial functions in future patches.

py3: handle iter/iterkeys+iteritems python3 divergence in import-checker

py3: use print_function in import-checker

py3: use absolute_import in import-checker

run-tests: make _processoutput picky about optional globs 1ad0ddf8cccc enabled lines that were not matched to be found later in cases of jitter. Unfortunately, in this model an optional line would always jitter to the end when it is not present. That is not ideal. It would be possible to do better, by queuing all writes until the end in case an optional line jitters, but for now, it is simpler to assume optional lines have a fixed place in the stream.

py24: remove check-code py24 notation We require python2.6+

py3: convert hghave output to text Before this, Python3 generated: b'skipped: unknown feature: not-py3k\n'

py3: convert prereq bytes to string in run-tests Without this, run-tests would generate: WARNING: Did not find prerequisite tool: b'python3.5'

record: deprecate the extension The feature has been moved into core behind the -i flag. We can safely deprecated the extension and point people at the --interactive flag in core.
