For example, `(module-declared? '(submod (planet dyoo/bf) reader) #t)'
shouldn't fail if there's no "main.rkt" to hold a `reader' submodule;
it should return #f.
Merge to 5.3, but updating cstartup.inc will require a manual merge.
MySQL:
- support multi-packet data rows
- fixed very old length-coding bug (24 vs 32 bit length)
- support large params via long-data packets
- 'any' pseudo-type for parameters
- distinguish 'blob'/'text', 'var-string'/'var-binary'
- read 'text' results as string, not bytes
SQLite3:
- enabled sql types tests
library (mostly in opt/c)
Specifically:
- add inlining declaration for ->i helper function
- modernized the opt/c contracts and improved them so that mutually
recursive define-opt/c functions recognize each other instead of
bailing out to the slow path.
- added =/c as an optimized contract
- improve the error message for the between and comparison opt
contracts
- adjust the blame struct so the name is created lazily, since opt/c
contracts just stick a copy o the contract into the thunk that
creates the name and we don't want to run those effects twice if we
can help it.
adjust 'one-of/c' and 'symbols' so they just use or/c (when possible)
improve or/c's stronger check so that, in the case that or/c is
getting eq or equal contracts, or/c's stronger check is as good as
'symbols'/'one-of/c's stronger check is.
This distinction is important after the introduction of chaperones and
impersonators, since accessing a key and accessing its corresponding value
may have different effects, and hash-keys should only trigger the former.
The immediate symptom was that `(provide (all-defined-out))'
didn't work in a `module+'-based submodule, but there were
also non-submodule ways to expose the problem.
The `get-handle' method provides the underlying Cairo surface for
a bitmap, while the unsafe `make-handle-brush' function supports the
use of a Cairo surface as a `brush%'.
Also, add `racket/draw/unsafe/cairo-lib', which simplifies access
Cairo from external libraries. Documenting `racket/draw/unsafe/cairo'
might be better, but that's a lot more work.
