conventions in 9.2.1 of the reference (altho the messages do
not yet do the extra level of indenting when a field is too
long, nor are there any field names ending in ...)
Also, fix the docs for the #:stronger argument to
make-contract, make-chaperone-contract, and make-flat-contract
A progress evt from a close input port must be initially ready,
and the primitive `peek-bytes-avail!' checks a progress evt
before checking whether the port is closed.
These changes resolve a race in `read-bytes-evt' and related evt
constructors.
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.
