If the `#:protocols` clauses of a `define-objc-class` form includes
errors, but it simplifies the declaration of protocols that are
introduced in different versions of a framework, and it's effectively
more compatible with the implementation before dc0898f5ef.
* match: check duplicate identifiers across list-no-order patters
* match: document that list-no-order doesn't support duplicate ids between sub-pats
* match: put duplicate id docs in a margin note between the two variants
Creating an executable with embedded DLLs means that the executable
can be truly stand-alone, instead of needing to be kept with its
DLLs in a relative subdirectory.
DLL embedding works by bypassing the OS's LoadLibrary and
GetProcAddress functions, and instead maps the DLL into memory
and performs relocations explicitly. Joachim Bauch's MemoryModule
(Mozilla license) implements those steps.
The expander as a linklet will be instantiated once, so there's no
need to capture references in closures among functions within the
expander. Add a "static" linklet compilation mode to inline the
variable addresses that would otherwise be referenced via a closure.
Although the change is intended to speed up the expander by avoiding
some indrections, it also reduces the bytecode size of the expander.
Bitmaps that track which linklet variables are used in closures turn
out to have been about 25% of the expander's bytecode size, since the
linklet has so many definitions.
This change adjusts the way that trust is threaded through bytecode
and the code inspector. In Racket v6.x, reading bytecode would fail if
the code inspector is non-original and if the bytecode contains a
reference to an unsafe operation. Now, reading bytecode doesn't fail
for that reason, but all bytecode is marked as non-runnable (even
without references to unsafe operations) when loaded under a
non-original code inspector. A `read` operation by itself remains as
safe as ever.
This commit also disables the bytecode validator. For now, the
validate can be re-enabled with `PLT_VALIDATE_LOAD`.
Make `s-exp->fasl` generate an encoding that can be parsed by any
future version of `fasl->s-exp`. The new format does not rely on the
runtime system's bytecode writer and reader.
Use stdout log reporting instead of stderr log reporting for status
reporting during the build, so that the status report is not
misinterpreted as an error.
The old reader used an internal option to short-circuit special-value
reading when a special value acts as a terminating "character". Expose
that shortcut by allowing 'special as an argument to
`peek-{char,byte}-or-special`, and update the reader to use it.
This commit merges changes that were developed in the "racket7" repo.
See that repo (which is no longer modified) for a more fine-grained
change history.
The commit includes experimental support for running Racket on Chez
Scheme, but that "CS" variant is not built by default.
