Leave it working in splicing mode. I prefer doing that over always
splicing them, since that would make a less uniform interface, so I
rather keep all options open. There is no longer a `#:nothing' keyword,
which is the main point of this downgrade.
(See mailing list discussion on "no-argument" for the reason.)
When a module is loaded from bytecode and then the value of
`use-compiled-file-paths' changes, an attempt to load a submodule
would fail, because source isn't used if the main module is
already declared, and the bytecode code is not used according to
`use-compiled-file-paths'. Make the bytecode path stick when it
is used once, so that submodule loads succeed, and make it work
even with `namespace-module-attach'.
The module-attach part of this protocol requires a change to the
API of a module name resolver: the notification mode gets two
arguments, instead of one, where the second argument is an
environment.
The libraries moved were:
- mzlib/control => racket/control
- mzlib/date => racket/date
- mzlib/deflate => file/gzip
- mzlib/inflate => file/gunzip
- mzlib/port => racket/port
- mzlib/process => racket/system
- mzlib/runtime-path => racket/runtime-path
- mzlib/shared => racket/shared
- mzlib/unit => racket/unit
- mzlib/unit-exptime => racket/unit-exptime
- mzlib/zip => file/zip
The old modules in mzlib are now pointers to the
new modules. These are all modules that were already
redirected in the documentation.
The new names are `prompt-tag/c` and `continuation-mark-key/c`
to keep the names consistent with the values that are being
contracted. Also updated the HISTORY file.
Add a `#:nothing' argument so the no-value value can be
made explicit --- based on discussion with Eli, but pending
further review.
Also, renamed `#:first' to `#:before-first' and `#:last' to
`#:after-last' to be more clear, more parallel ro `#:before-last',
and avoid a collision with prominent function names.
The generics library now generates a `name/c` macro
for a generic interface `name`. The combinator can be
used to contract instances (or constructors) of a
generic interface across standard contract boundaries.
See PR 12860; some of problem related to the PR were "fixed" by
adjusting the guarantees that are specified in the documentation.
Another problem was that non-consecutive bytes could be returned.
For all currently supported platforms, the result was already
portable, despite the documentation's hedging.
Also fixed up the documentation in other ways, such as the fact
that `seconds->date' returns a `date*'.
* The old function was removed completely, people will get it from
`racket/base' anyway.
* I also removed its documentation. I thought about leaving a note in,
but if `define-ffi-definer' is the preferred style, then this should
be done when there's a way to make `define-ffi-definer' use it. (Eg,
some new #:keyword that adds a way to change the defined name.)
* Note that the function is added to `racket/private/string' and not to
`racket/string' because the latter deals only with strings, and the
new function accepts byte strings too. It might be better to start a
new `racket/regexp' module for these functions.
Add extra intitial-message lines, use "..." on a field name
to indicate that it could reasonably be hidden by default,
and refine some existing messages.
Includes the addition of 'overflow and 'start-overflow-work
events, whcih are effectively specializations of 'sync and
'start-work to expose overflow handling.
Also, fix a bug related to a potential GC during mark-stack
restore from a lightweight continuation.
Added alises for call-with-continuation-prompt,
abort-current-continuation, and call-with-composable-continuation.
Also allow % and fcontrol to take an optional prompt tag argument.
The new predicates are `progress-evt?' `thread-cell-values?',
`prefab-key?', `semaphore-peek-evt?', and `channel-put-evt?'.
These were used internally, and now they appear in contract
error messages.
When supplying an accessor to redirect, either the corresponding field
must be accessible through the current inspector, or a mutator for
the same field must be redirected, too.
Stevie realized that we need this constraint; otherwise, impersonators
can implement mutator-like behavior even when the mutator is otherwise
secret.
Add `raise-argument-error', `raise-result-error', `raise-arguments-error',
and `raise-range-error'.
The old convention was designed for reporting on a single (sometimes very
long line). The new convention is
<name>: <short message>
<field>: <detail>
...
If <detail> is long or itself spans multiple lines, then it may
also use the form
<field>:
<detail>
where each line of <detail> is indented by 3 spaces.
Backtrace information is shown as a multi-line "context" field.
