Combined with a schemify improvement that inlines imported predicates
to expose the record-type test to Chez Scheme, this chage enables
cptypes to prune useless inlined `wrapped-object` selector branches.
That improvement, in turn, reduces code size and redundant checks on
objects that have contracts.
When a `lambda` form is marked as a method (for arity error reporting)
through a property, translate that to a static flag on the procedure,
instead of a call to `procedure->method`.
The only way we have to attach static information is through the
procedure name, so the encoding already in place for "no name" and
"path-based name" is extended to support a method flag.
Since procedures have names that are attached more directly by the
schemify pass, remove simple `let-values` forms wrapping procedures.
This shortcut improves the result of the lifting pass in some cases.
Record types with unnamed fields can be significantly more compact,
excdeption in combination with the constrain the the fields all
contain Scheme objects. Saves 2% for DrRacket's initial footprint.
We had to give back some space savings to avoid potential problems
with allocating in the event callback and running out of stack
space[?] when passing an argument. We get to keep most of the
improvement though.
Use `--no-user` for the `raco setup` that is supposed to finish a
bundle. Otherwise, things installed in user scope for the same Racket
version (i.e., the one being bundled) can interfere with the bundling
process.
Fix a regression in 712494312a, and change other other two printers to
be more consistent for
#lang racket
(struct s () #:transparent)
(define a (s))
(pretty-print (list (cons a 0) (cons a 0)))
A regexp can match while having sub-patterns that are not used in
the match. In regexp-replace, the "insert" argument can refer to
these unused sub-matches. If a function is given for the "insert"
argument, it will receive these unused submatches as #f values.
If a string or byte-string is given, then any reference to an
unused sub-match (by means of a back-reference) is treated as the
empty string or byte-string.
Fixes#3032.
When logging GC debugging, a pecentage after the time for a GC reports
what fraction was extra steps after GCing proper, especially the extra
step of memory acounting when that is enabled.
Also, avoid Chez Scheme gensyms even more. Otherwise, using low-level
facilities like `dump-memory-stats` can force the unique name of a
gensym used for a structure type, which causes it to be permanent,
which could be exactly what you don't want when debugging a
memory-rentention problem.
In `compiler/private/mach-o` --- which is reachable via `racket` due
to being a dependency of `setup/dirs` --- delay the call to
`cross-system-library-subpath` until needed.
