Using GC_free() on runstacks was a way of reducing leaks with
conservative GC, but the implementation of prompts for delimited
continuations evolved in a way that is incompatible with using
GC_free(). The recent change to make certain runstack links weak
particularly exposed the mismatch.
To obtained more fine grained results, I have exploded the pipeline by
splitting jobs compiling each of the versions of racket (cgc, 3m and
cs). I have then used each of these to run the respective tests, and
each test collection have its own job as well. This is a refactoring
to obtain better results and part of the long term plan of being able
to generate a user/contributor readable at-a-glance dashboard for the
racket ci system.
Unfortunately we are hitting the capabilities of gitlab, due to its
inability to represent pipeline dags. Although Gitlab CI maintainers
are aware of this a solution within the platform is being constantly
delayed - we might have to look elsewhere or if we are really
motivated, develop an in-Racket CI system.

Steps to create this certificate:
openssl genrsa -out key.pem 2048
openssl req -new -sha256 -key key.pem -out csr.csr
openssl req -x509 -sha256 -key key.pem -days 3650 -in csr.csr -out certificate.pem
cat key.pem certificate.pem > test.pem
When filling out the information for the certificate, keep the same
details - some tests depend on it.
Bring CGC and 3m in line by breaking weak links in CGC only after
ready level-1 finalizations (which correspond to will executors) have
been queued. The chage delays clearing of the weak link until after
the finalizer is run.
by `contract-out` instead of `->`
This seems to save about a second of startup time in (non-cs) DrRacket
and about .1 seconds in drracketcs.
The code is also theoretically more easily inlined. Still not easy enough, however.
In a pattern like
(let loop ([l l])
(define v (syntax-e l))
(cond
[(null? v) 'done]
[else
(loop (datum->syntax #f (cdr v)))]))
the running time was O(N^2) for a list of syntax objects of length N.
That pattern is relevant for traversals that use `syntax-case` like
(let loop ([l l])
(syntax-case l ()
[(a . b) (loop #'b)]
[() 'done]))
Avoid bad behavior by recording in an weak hash table certain pairs
that were previously been produced by `datum->syntax` internally so
that they can be used as-is.
Mainly for cross-compilation with a Windows target, the Racket CS
build process may need to run `lz4` as an external program. In that
case, complain when `lz4` isn't found, instead of letting `system*`
complain about getting `#f`.
Change the condition for filtering leaf contracts via `eq?`.
Before, we looked for flat or chaperone contracts.
After, look for flat or trusted contracts. So:
1. untrusted chaperones with side effects that are unsafe to drop are not
dropped, and
2. impersonator contracts can now be dropped (object/c, recursive-contract)
When compiling with -Werror (./configure CFLAGS="-Werror" ...),
the test to see if mbsrtowcs exists
failed with pointer type of incompatible type, is char **, should be
const char **. It would proceed to assume mbsrtowcs didn't exist.
