The `current-environment-variables' parameter determines the current
mutable "environment variable set". If that set is the initial one for
a Racket process, then using the set corresponds to working with OS
environment variables. Otherwise, it's really just a hash table that
is packaged up as OS environment variables if a subprocess is created.
The new environment-variable interface works in terms of bytes, instead
of assuming that environment variable names and values fit in a string
encoding.
The string-based `getenv' and `putenv' are still available as
convenience wrappers. The checking on environment-variable names
for those wrappers is a little tighter, preventing any attempt to use a
name that contains "=".
A symptom of mismatched `for-label' imports was that searching for "<="
would show red-underlined links to the `plai/{gc2/}mutator' documentation.
Merge to v5.3.4
When places are not enabled, then `raco setup' uses multiple
Racket processes that commuincate via pipes. Don't try to send
a place channel over a pipe.
Merge to v5.3.4
The code duplication was there only to support
constructing the name for the optimized contract;
instead we actually just built the name as we go
(the old version actually built the old contract
and then used that to get the name)
also:
- racket/contract/base now requires basic-opters.rkt
so all of the opters are registered when racket/contract/base
is loaded, not just the non-basic ones
- fix the ordering of the names of subcontracts in or/c
- make opt-contracts print a more meaningful name
for online expansion errors
This avoids drawing the margin highlight when it isn't inside the
region being repainted and it avoids even figuring anything out about it
when there is currently no error range
NOT for the release branch
Specifically, allow a name to be specified with an
extension such that subsequent uses of those extensions
will replace mixins instead of adding new ones
This commit extends make-base-eval, make-base-eval-factory, and
make-eval-factory with an #:eval and input-program inputs so that
these functions are more like racket/sandbox make-evaluator.
This change revisits commit eb7fa6f066. I think the problem
is not in the rendering of index entries but on the generation
side. The generator was converting Xexprs to strings, except
that strings were left as-is, which is inconsistent. So,
I've reverted commit eb7fa6f066 and fixed the generator.
