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.
