Also, change floating-point handling to be like the MSVC build by
default, where the process is left in double-precision mode and
the mode is changed for exfl operations.
Includes repairs for integer-size mismatches in uses of Windows
threads.
The error message for the guard used an incorrect contract.
Also removed an unused line that allows a box value in the
property. I don't think it was possible to trigger this line
anyway because of the dynamic check.
Support PNG-encoded icons in ".ico" files and executables.
For executables, instead of supporting only new icons that match the
sizes and encodings of existing icons in an executable, support
arbitrary replacement icons in an executable.
The improved funcitonality relies on a new library (currently
private) for general updates to a Windows executable's
resources.
In a case like
(let-values ([(X ...) (with-continuation-mark M_k M_v
(values M ...))])
....)
where the bytecode compiler cannot convert to a sequence of `let`
bindings, make the JIT implement `values` as delivering argument
results directly to the corresponding variable locations.
When `call/cc` and `call/ec` were moved out of `#%kernel`, the
`let/cc` and `let/ec` macros changed to refer to
`call-with-current-continuation` and `call-with-escape-continuation`.
Move `call/cc` and `call/ec` again and restore the macros, so that
matching on the expansion of the macros (e.g,. in the web server's
language that looks for `call/cc`) work as before.
A `module-suffixes` entry in a collection's "info.rkt" adds a
file suffix that is meant to be recognized globally (i.e., in
all collections) by all Racket tools.
The new fields are reported by `compiler/module-suffix` library, which
is (so far) used by `raco setup`.
Note that if package A includes files with a suffix that is registered
by package B, then A should have a dependency on B, but `raco setup`
cannot currently detect that such a dependency is needed. That
dependency is likely to happen, anyway, since package A is likely
using libraries form package B.
Comments in the implementation suggest that a timestamp
specialization was intended for directories, which makes
sense given that directory-modification dates are
not preserved when unpacking an archive. The change
also affected all bytecode timestamps, however, which
can create inconsistencies across package creations.
The `from` string argument is converted to a regexp and cached. When `from` is
a mutable string this can cause wrong results in the following calls
to string-replace. So the string is first converted to an immutable string to
be used as the key for the cache.
When `place` expands, the body of the `place` form is placed into a
`(module* place-body-<n> #f ....)` submodule.
The `place` form previously placed its body in a lifted function,
where the function's exported name was based on
`(current-inexact-milliseconds)`. The generated submodules have
deterministic names, so that compilation is deterministic, and
submodule names don't collide (unlike exported function names) when
multiple `place`-using module are imported into some other module.
Also, using a submodule avoids the problem that the clock doesn't
change fast enough on Windows.
Those aliases were moved out of `#%kernel` as part of the
determinstic-bytecode changes, but putting them in
`racket/private/pre-base` meant that they weren't included in
`mzscheme` or Pretty Big. The new location is with `let/cc`, which
makes more sense, and makes them picked up by `mzscheme` and Pretty
Big.
