Caching parse results uses a lot of memory, even if they expire after
2 minutes, so it won't scale up to many simultaneous users.
But some excessive memory use seems to be caused by space leaks in
(the Haskell binding to) the C run-time system, and these should be fixed.
For example, flushing the PGF cache does not release the memory allocated
by the C run-time system when loading a PGF file.
Most PGF web API commands that produce linearizations now accept an
unlexer parameter. Possible values are "text", "code" and "mixed".
The web service now include Date and Last-Modified headers in the HTTP,
responses. This means that browsers can treat responses as static content and
cache them, so it becomes less critical to cache parse results in the server.
Also did some cleanup in PGFService.hs, e.g. removed a couple of functions
that can now be imported from PGF.Lexing instead.
The old type was [String] -> String. This function was only used
in GF.Text.Lexing.stringOp, which now uses (unwords . bindTok) instead,
with no change in behaviour.
The capitalization of the first word was done in GF.Text.Lexing.stringOp,
but is now done in the functions unlexText and unlexMixed in PGF.Lexing.
These functions are only used in stringOp and in PGFService (where the change
is needed), so the subtle change in behaviour should not cause any bugs.
Only change the first word to lowercase if the original input is not found in
the grammar's morphology. This allows parsing of sentenses starting with "I" in
English, nouns in German and proper names in other languages, but it can make
the wrong choice for multi-words.
The PGF web API commands parse, translate, translategroup, c-parse and
c-translate now support a lexer parameter. Possible values are "text",
"code" and "mixed".
This is used in the Wide Coverage Demo App to save one server roundtrip.
