dirstate: move filefoldmap to dirstatemap As part of moving the dirstate storage logic to a separate class, lets move the filfoldmap computation to that class. This will allow extensions to replace the dirstate storage with something that persists the filefoldmap. Differential Revision: https://phab.mercurial-scm.org/D754

dirstate: move nonnormalentries to dirstatemap As part of moving dirstate storage to its own class, let's move the nonnormalentries logic onto the dirstatemap class. This will let extensions replace the nonnormalentries logic with a persisted cache. Differential Revision: https://phab.mercurial-scm.org/D753

dirstate: create new dirstatemap class This is part of a larger refactor to move the dirstate storage logic to a separate class, so it's easier to rewrite the dirstate storage layer without having to rewrite all the algorithms as well. Step one it to create the class, and replace dirstate._map with it. The abstraction bleeds through in a few places where the main dirstate class has to access self._map._map, but those will be cleaned up in future patches.

style: always use `x is not None` instead of `not x is None` Differential Revision: https://phab.mercurial-scm.org/D842

templatekw: add new-style template expansion to {manifest} The goal is to allow us to easily access to nested data. The dot operator will be introduced later so we can write '{p1.files}' instead of '{revset("p1()") % "{files}"}' for example. In the example above, 'p1' needs to carry a mapping dict along with its string representation. If it were a list or a dict, it could be wrapped semi-transparently with the _hybrid class, but for non-list/dict types, it would be difficult to proxy all necessary functions to underlying value type because several core operations may conflict with the ones of the underlying value: - hash(value) should be different from hash(wrapped(value)), which means dict[wrapped(value)] would be invalid - 'value == wrapped(value)' would be false, breaks 'ifcontains' - len(wrapped(value)) may be either len(value) or len(iter(wrapped(value))) So the wrapper has no proxy functions and its scope designed to be minimal. It's unwrapped at eval*() functions so we don't have to care for a wrapped object unless it's really needed: # most template functions just call evalfuncarg() unwrapped_value = evalfuncarg(context, mapping, args[n]) # if wrapped value is needed, use evalrawexp() maybe_wrapped_value = evalrawexp(context, mapping, args[n]) Another idea was to wrap every template variable with a tagging class, but which seemed uneasy without a static type checker. This patch updates {manifest} to a mappable as an example.

templater: adjust binding strength of '%' and '|' operators (BC) This makes 'foo|bar%baz' parsed as '(foo|bar)%baz', not 'foo|(bar%baz)'. Perhaps it was a mistake that '%' preceded '|'. Both '|' and '%' can be considered a kind of function application, and '|' is more like a '.' operator seen in OO languages. So IMHO '|' should have the same (or higher) binding as '%'. The BC breakage should be minimal since both '|' and '%' operators have strict requirements for their operands and 'foo|bar%baz' was invalid: - right-hand side of '|' must be a symbol - left-hand side of '%' must be a dict or list - right-hand side of '%' must be a string or symbol

templatekw: just pass underlying value (or key) to joinfmt() function Before, iter(hybrid) was proxied to hybrid.gen, which generated formatted strings. That's why we had to apply joinfmt() to the dicts generated by hybrid.itermaps(). Since this weird API was fixed at a0f2d83f8083, we can get rid of the makemap() calls from join().

scmutil: extract helper functions that returns human-readable change id We do "'%d:%s' % (ctx...)" at several places, so let's formalize it. A low- level function, formatrevnode(ui, rev, node), is extracted so we can pass a manifest rev/node pair. Note that hex() for manifest output can be replaced with hexfunc() because it is printed only when debugflag is set. i18n/de.po is updated so test-log.t passes with no error.
