There could be many more functions that produce immutable strings
directly, and we want the default functions to do that in some future
language. For now, these three rae the most immediately useful for
avoiding unnecessary allocation in Racket CS.
Mostly reverts ee4ceb7ae4 and tries a different approach. The prevoius
approach did not handle the case where the module begin instantiated
was tiggered by a module at a different (higher) phase.
Closes#2981
Eliminates another ~300 instantiations from `racket -cl racket/base`.
small-scheme.rkt is no longer used in `racket/private`.
c.rkt was an accidentally-committe file.
Maybe there's a problem in `rktio_poll_add_connect` that I just can't
see, or maybe it's a Mac OS bug, but `rktio_poll_add_connect` doesn't
seem to reliably wake up the process when the TCP connection becomes
ready. Traditional Racket happens to avoid the problem by registering
the connection file descriptor with the semaphore table; doing that
for Racket CS also avoids the problem there.
Take advantage of new guarantees/support for immutable strings within
a Chez Scheme symbol representation. Consistent use of immutable
strings at the boundary avoids potential non-determinism.
This simplifies the expander logging in some places and adds logging for arming/disarming and scope changes (eg syntax-local-introduce) so the macro stepper can better track term identity.
This relies on corresponding changes to the racket/macro-debugger repo.
@samth requested a clarification of the condition under #2959
Hopefully this comment makes it clear that we require the condition in order not to tarball and upload the clang artifact on Linux.
The choice not to test both the gcc and clang builds was made to save time and because we are not testing the compiler itself, but racket.
Hopefully by the time we get these production compilers, they are generating correct code.
Fix a test to be less sensitive to the cost of non-tail recursion when
the goal is to check reachability of values from the current
continuation.

This breaks existing packages; see https://github.com/greghendershott/aws/issues/64
for an example.
Unfortunately, we probably have to live with this limitation of the
interface because of existing code.
This reverts commit 966399dec6.
It's not available with musl, either, musl intentionally
doesn't provide a preprocessor test, and we're avoiding
(for now) `configure`-time tests in the style of autoconf.

Don't run cptypes, when cp0 is disabled, for example with
(run-cp0 (lamba (cp0 x) x)
This is easier to understand because run-cp0 is a single point to control
all the cp reductions. The reductions in cptypes can be independently disable
using enable-type-recovery.

Use “cmd.exe” on Windows. This enables us to have a list (of length one on
macOS and Windows) of launcher executables on all platforms, and use
send-url/unix, now renamed to send-url/simple, to launch all URLs without a
query or fragment.
