Although `raco pkg` doesn't use a package's ring number, it's useful
to preserve for other tools (like the pkg-build service). Adjust `raco
pkg catalog-copy` and `raco pkg catalog-info` to recognize and store a
ring number.
A mistake in the rktio conversion causes a crash if certain functions,
such as `directory-exists?`, are used before certain other functions,
such as `resolve-path`.
Thanks to Alex Harsanyi for the report.
The rktio conversion lost the deregistration of file descriptors in an
internal fd-to-semaphore table building on kqueue/epoll, causing the
wrong semaphore to be checked for a later recycling of the file
descriptor. This bug mainly affects Linux and ports created by
`subprocess`, since kqueue is not used for pipes on Mac OS and BSD
variants. The bug does not affect network sockets (which are the
primary intended clients of epoll/kqueue support), since the relevant
semaphore is deregistered when a socket is closed.
Thanks to James Bornholt for discovering the problem and providing the
repair.
Closes#1769
Fix a problem with compile-time bindings added to a
namespace created by `module->namespace` for a module
that does not have a source file.
Possibly, there's a different fault that should be fixed that caused a
binding to use the module's instantiation-time module path index
instead of its compile-time module path index (which is what happens
when a file is involved). This repair fixes the problem in a general
way, though, and leaves further improvement to the reimplementation of
the expander in Racket (which already does not suffer from the bug).
Thanks to Alexis for providing the example.
In a non-tail position, a JIT-generated application of `apply`
retained the argument list until the called function returned.
Fix it to drop the reference to the list before the function
is called.
And unquoted-printing string contains a string to `display` in all
print modes. Although it could be implemented with a structure type
that has a printing function, `raise-arguments-error` further treats
unquoted-printing strings specially by not using the error value
conversion handler, so it reliably produces literal text in the error
message; that way, `raise-arguments-error` can be used to construct
more error messages.

New example based on code from Jens Axel Soegaard.
Caveat: I've run this in DrRacket with (require (for-syntax syntax/parse)) to verify the three distinct outputs, but am submitting this PR in-browser, so I haven't run the doc build on it myself.
Before this line, it says the function flows from providing module to requiring module.
After this line, it says the argument travels back from requiring moduleo to providing module.
I believe that argument supplying and function invoking should happen at requiring module, rather than providing module.
For the French counting, "une" is not quite correct. It is the female form for "one" as an article. It is much more common to count "un", "deux", "troix", "quatre", "cinq", ....
The hack to implement `_union` without help from libffi failed when
the total size of the variants is too large. Try a different approach,
which involves a bet that the total size plus whether the content is
all floating-point numbers will be enough information for most cases.
Relevant to #1351
The simpler example uses `dynamic-require`, which will hopefully set
readers on a better path if they don't need a REPL and the associated
complexities of `load` and `eval`.
The switch to rktio swapped the sense of "signal" and "sigset"
incompletely, and "signal" on Solaris is the one that resets
the signal handler to SIG_DFL.
