Additionally this adds macros that distinguish between the chaperone redirects of prop-only vector
chaperones, function chaperones, and structure chaperones since each of these may store a vector
in the redirects field.
They take approximately 20 minutes, which causes regular timeouts.
Disabling them will make our testing much more predicatable, and
the number of issues found is very small.
Auto fields were incorrectly recorded as immutable in a structure type
that is first generated from the prefab struct key instead of
`make-struct-type`.
Thanks to Deren Dohoda for the report.
When `--update-deps` (which is implied by `--all`) was used on
user-scope packages that depend on installation-scope packages, the
installation-scope dependencies were treated as missing, which forced
an update of the user-scope packages. Check both scopes for
dependencies.
Closes#1730
The `file/cache` relies on matching the text of a message, and the
text had changed to have less information on Unix, including whether
the problem was with the source or destination file. Add a notion of
error step to rktio and use it to improve the `copy-file` message.
Report a proper error when path decoding fails, instead of
synthesizing a path hat shouldn't exist. The rktio conversion
made it much easier to report the error at the Racket level
like other filesystem errors.
In the process of extracting minimal Windows path encoding for rktio,
I noticed a decoding issue with a path that ends with an unpaired
high-surrogate value. Add a suitable tests and fix the old decoder
(although it will probably go away).
Closes#1721, which points out that the `for/list` expansion
introduced in commit 5e94a906cd interacts badly with a body
that captures a continuation plus Racket's current implemenation
of continuations.
When Racket one day gets a better implementation of continuations,
this change could be considered again, but the general question is
whether programs can detect or be affected by the size of the
continuation (when the programs don't directly control the
continuation creation --- otherwise continuation marks obviously
expose the size).
Provide a compatibility layer to bridge the old (not completely
documented) `scheme_fd` interface and rktio. The old interface is
used by the Gtk implementation of `racket/gui`, for example.
Process handling relies on SIGCHLD being blocked, but signals are
blocked per-thread in Linux, so SIGCHLD needs to be blocked before new
threads are created.
For `open-output-file`:
Move 'replace mode handling out of rktio and into the client.
Formerly, on Windows, 'replace mode was just 'truncate with a fallback
for permission problems, so this change makes it delete an existing
file and replace it, which is more consistent with how 'replace has
always worked on Unix.
In 'truncate/replace mode, if a truncating open fails due to a
permission error and the file exists, then try again as a 'replace.
That's how it worked on Windows before, and now it's how Unix works.
