The new names are `prompt-tag/c` and `continuation-mark-key/c`
to keep the names consistent with the values that are being
contracted. Also updated the HISTORY file.
Add a `#:nothing' argument so the no-value value can be
made explicit --- based on discussion with Eli, but pending
further review.
Also, renamed `#:first' to `#:before-first' and `#:last' to
`#:after-last' to be more clear, more parallel ro `#:before-last',
and avoid a collision with prominent function names.
The generics library now generates a `name/c` macro
for a generic interface `name`. The combinator can be
used to contract instances (or constructors) of a
generic interface across standard contract boundaries.
A arity-reduced procedure-valued `prop:procedure' was not handled
correctly, for example.
A good candidate for random testing? I had the right kind of test in
place, but only for an arity of 1. It turns out that testing any other
arity would have exposed the problem, so now there are tests with
arity 0. If I had randomly generated procedures instead of manually
constructing `f0' through `f1:+' in "procs.rktl", then maybe I would
have more naturally generalized the arity testing, too. Then again,
I did already have relevant inputs, and it was the testing of inputs
that was too specific.

See PR 12860; some of problem related to the PR were "fixed" by
adjusting the guarantees that are specified in the documentation.
Another problem was that non-consecutive bytes could be returned.
* The old function was removed completely, people will get it from
`racket/base' anyway.
* I also removed its documentation. I thought about leaving a note in,
but if `define-ffi-definer' is the preferred style, then this should
be done when there's a way to make `define-ffi-definer' use it. (Eg,
some new #:keyword that adds a way to change the defined name.)
* Note that the function is added to `racket/private/string' and not to
`racket/string' because the latter deals only with strings, and the
new function accepts byte strings too. It might be better to start a
new `racket/regexp' module for these functions.
As the documentation says, it's supposed to be ok to use the
same evt multiple times or in multiple threads, but an internal
buffer was allocated incorrectly, so that multiple/concurrent
uses could go wrong.
Closes PR 12860
Add extra intitial-message lines, use "..." on a field name
to indicate that it could reasonably be hidden by default,
and refine some existing messages.
Includes the addition of 'overflow and 'start-overflow-work
events, whcih are effectively specializations of 'sync and
'start-work to expose overflow handling.
Also, fix a bug related to a potential GC during mark-stack
restore from a lightweight continuation.
This was broken in the class100 port. The init arguments
previously handled by the class100*/kw macro need to be
explicitly passed down.
Also, an (init-rest) is needed at the leaves of the class
hierarchy to ensure that internal super init args don't
leak via error messages. (the class100 macro always
inserts these)
Added a test file so similar breakage is detectable in the
future.
1. Lots of #lang-ization, other racketizations, code improvements, etc.
2. Some files that were not working now do.
3. "collects/tests/aligned-pasteboard" had some files that were near
duplicates of "collects/mrlib/private/aligned-pasteboard/tests".
I've removed the former since in a few places it looked like an older
version (eg, there were bogus references to a non-existent
"utils.rkt"). The former has more files that are in runnable
condition now.
4. There are plenty of tests that look like they're failing, but it
wasn't shown since they just return #f, and when they were running
with a "-f" these results weren't displayed.
5. I have no idea about the code, this is all just reshuffling and minor
editing.
Added alises for call-with-continuation-prompt,
abort-current-continuation, and call-with-composable-continuation.
Also allow % and fcontrol to take an optional prompt tag argument.
Types for nan?, infinite?, pi.f, exact-round, exact-floor, exact-ceiling,
exact-truncate, degrees->radians, radians->degrees
Extended tc-random-testing: generates exact integers and rationals now
Fixed types of sinh, cosh and tanh to account for underflow and NaNs
