Name handling formerly interned symbols along the
way to allocating a plain string, which takes effort
and causes changes to the symbol table, which forces
a minor GC to traverse the whole symbol table. Skip
unnecessary symbol-interning steps.
Unless `-s` or `--submodule` is specified, and as long as each
test is run in its own place or process, require a `configure-runtime`
submodule of the specified module before running the module or its
`test` submodule.
For example, this change makes `raco test` run `htdp/bsl` tests
with printing configured correctly for `htdp/bsl`.
Refine the changes in 16c198805b so that `(define id ... id ... )` at
the top level compiles more consistently when `id` is an identifier
whose lexical context does not include `#%top`.
When `compile` is used on a top-level definition, do not
create a binding in the current namespace, but arrange for
a suitable binding to be in place for the target namespace.
Closes#1036
This repair adjusts the bug fix of commit 769ad3e98. That older commit
ensured that `sync/enable-break` doesn't both break and accept a
channel message or semaphore wait. But it effectively disables those
actions if the break is continued.
Instead of (partially!) ending the `sync` get out of semaphore
and channel queues so that no event can be selected during
the break, and then get back in line if the break is continued.
When a path is made relative for marshaling to bytecode, record
a list of byte strings in stead of a platform-specific relative
path.
For syntax-object source locations, convert any non-relative path to a
string that shows just the last couple of path elements preceded by
".../". This conversion avoids embedding absolute paths in bytecode,
but at the cost of some information. A more complete and consistent
solution would invove using a module-path index instead of a path, but
that would be a big change at several layers.
Make room in the bytecode format for source locations and 'paren-shape
property values for syntax objects. Saving source locations increases
bytecode size by about 10% on average.
Also, convert the internal representation of syntax properties to
use immutable hash tables, instead of lists.
The `prop:expansion-contexts` property can control the expansion
of a rename transformer in much the same that conditionals on
`(syntax-local-context)` can control the expansion of other
transformers.
These avoid one layer of currying and are more efficient, getting
about a 1.3x speed up on this program:
#lang racket/base
(module server racket/base
(require racket/contract/base)
(provide
(contract-out
[f (-> integer? boolean? char? void?)]))
(define (f i b c) (void)))
(require (submod "." server))
(time
(for ([x (in-range 10000000)])
(f 1 #t #\x)))
