Adjust the makefile that ends up in <builddir> with `--enable-cs` or
`--enable-csdefault` (as opposed to `--enable-csonly`) so that `make
racketcs` doesn't imply `make racket3m` if `--enable-racket` has
supplied an existing Racket.
Also fix `make install-cs` related to GRacket for the case that Racket
3m/CGC isn't built.
Relevant to #2683
While a continuation is set up to avoid retaining runstacks, partly by
storing a prompt ID instead of a prompt record, prompt records can
remain on the C stack and get captured anyway. Mitigate that problem
by making the runstack link weak in some prompt record.
Racket CS doesn't have this problem, of course.
Relevant to jeapostrophe/lux#10
Add `single-flonum-available?` and `read-single-flonum`, where the
latter controls whether numbers that have an "s" or "f" exponent
marker are parsed as single-flonums are normal flonums. The parameter
is disabled by default, which changes the meaning of most existing
code that has a literal number with "s" or "f", including `+inf.f`,
`inf.f`, and `+nan.f`.
The compiler constant-folds `single-flonum-available?` and
`real->single-flonum` on a literal number, so use a combination of
those to replace most uses of a single-flonum literal. Single-flonums
within quoted data are less convenient.
These jobs are currently only running on schedules in order
to avoid blocking out day time activity CI.
It also fixes a build in the build and test script used by gitlab ci
for emulation where configuration arguments are not recursively passed
properly.
After the change that makes printing of struct ignore print-pair-curly-braces
it is possible to simplify the code in io/print and the associated tests.
For traditional Racket, fix `bytes-utf-8-index` to accept 5 arguments
as documented. For Racket CS, fix `bytes-utf-8-index` to return an
index relative to the byte string's start.
Closes#2670
When `print-pair-curly-braces` is true, change the built-in printer to
not use curly braces to group a constructor with its argument.
Restrict its effect to quoted lists, which is more what you expect and
more consistent with `pretty-print`.
Also, change `pretty-print` to not use `{` when using the `list`,
`list*`, `cons`, or `mcons` constructors.
Closes#2662
On case-sensitive filesystems on macOS, these are
distinct (leads to a file not found error). On
case-insensitive systems, the change should not matter.
These changes are intended to address "input port is closed" errors
that have been showing up with Racket CS, possibly because its
scheduler exposed missing synchronization.
Instead of having schemify generate `letrec*` and convert as needed
through a Chez Scheme macro, have schemify perform any necessary
conversion to get the right use-before-definition error messages and
`call/cc` interaction.
This change improves the conversion, since schemify has more
information about bindings, but it also avoids sending Racket terms
through a macro-generating macro at the Chez Scheme level. Avoiding
the macro-generating macro avoids a kind of leak in Chez Scheme, where
a gensym used in a template may become ineligible for GC due to the
way `free-id=?` may both reify the gensym's unique name and attach a
property to the gensym.
Using a will executor to turn a reference from weak to strong still
seems like an ok idea, but it needs to be a regular will executor,
because a custodian-registered value is likely to involve have a
nested self-reference.
More generally, repair the internal `exe-relative-path->complete-path`
function to work when the current directory is not the original
current directory and `racket` is started with a relative path.
Currently, it happens that `exe-relative-path->complete-path` is
called with a potentially different directory only by
`get-lib-search-dirs`.
When the compression format changed to LZ4, which is much faster to
decompress than zlib, the configure script changed to enable
compression by default. Bytecode tends to benefit all around from
compression, but the boot files take 20ms or so longer to load --- not
a lot of time when loading typical amounts of code, but a signficiant
cost for a minimal startup. This commit allows compression to be
controlled separately for boot files, and it configures them as
uncompressed by default.
