This tweak avoids adding extra space when the white-label font is
taller than the line it's attached to. It also makes the label
disappear in IE 6, but I think we can live with that.
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.
As the documentation says, it's supposed to be ok to use the
same evt multiple times or in multiple threads, but an internal
buffer was allocated incorrectly, so that multiple/concurrent
uses could go wrong.

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.
This fixes drdr, which is using a pre-submodules version of racket.
There was also a use of one-argument `string-join' that is fixed that
has been there for a while but drdr uses the api directly.
- added some color (mostly to try to disambiguate the lines)
- several of the things named '*-element' actually belong under content, not element.
- element has 'content', not the substructs.
- convertible?s are content's.
- the 'content' field in an element is not a list, but simply a content.
- there are a bunch of things under target-element.
- image-element was missing fields
- collect-element was missing the collect field
Simplified code, and additional testing for redundant properties, and
for properties that can be collapsed into a parent directory (this might
be dropped or used only for notification on differences, see
commentage).
Also, make drdr test itself reflectively.
The code is improved, and also the default changes for *.rkt files:
there is no need for any flags -- "-q" is redundant, and with no flags
it's doing "-u" which is the same as "-t" (with an added "-N").
This was broken in the class100 port. The init arguments
previously handled by the class100*/kw macro need to be
explicitly passed down.
Also, an (init-rest) is needed at the leaves of the class
hierarchy to ensure that internal super init args don't
leak via error messages. (the class100 macro always
inserts these)
Added a test file so similar breakage is detectable in the
future.
1. Lots of #lang-ization, other racketizations, code improvements, etc.
2. Some files that were not working now do.
3. "collects/tests/aligned-pasteboard" had some files that were near
duplicates of "collects/mrlib/private/aligned-pasteboard/tests".
I've removed the former since in a few places it looked like an older
version (eg, there were bogus references to a non-existent
"utils.rkt"). The former has more files that are in runnable
condition now.
4. There are plenty of tests that look like they're failing, but it
wasn't shown since they just return #f, and when they were running
with a "-f" these results weren't displayed.
5. I have no idea about the code, this is all just reshuffling and minor
editing.
There were many such properties that were leftover from before the big
GUI rewrite where the gracket executable was needed, and now there is no
longer any need for these things. There are two exceptions:
* There is a drdr feature that forces all tests that use gracket to run
sequentially, which is used for tests that rely on some actual state
of shown windows. I ran all of the files and monitored for windows
popping up, and left the test to use gracket in these cases.
* There are a few cases where running "racket -f <file>" resulted in an
unbound identifier, whereas "gracket -f <file>" does not. These are
because of the different global namespace, and I will fix them (props
and the files) in a different commit.
One of the expected results of this is that a drdr might run faster,
because the serial-running hack above should now be applied only where
relevant. (And some of the drracket tests are very long.)
This commit is pushed by itself to identify possible problems with a
drdr run that tests only this change.
Check that the entries are sorted, and check that there's a
`responsible' for all files on disk, except for known exceptions. It
might be better to use "git ls-tree HEAD <path>" instead of looking at
the filesystem, but then it won't work on drdr.
For example, a syntactic form box is labeled with "SYNTAX". Forms
such as `defform' and `defthing' now support a `#:kind' option
for setting the label.
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.
Revise the subword matching to have three different levels for full
match (= a permutation of the input), a generic match for all parts, and
everything else.
Instead of just one array for exact results and one for all the rest,
use one array for each possible comparison result, and concatenate them
all for the final list.
Types for nan?, infinite?, pi.f, exact-round, exact-floor, exact-ceiling,
exact-truncate, degrees->radians, radians->degrees
Extended tc-random-testing: generates exact integers and rationals now
Fixed types of sinh, cosh and tanh to account for underflow and NaNs
When the theme-specified default font has a localized name,
using it as a Pango faily name doesn't work, with the result that
text on controls could be truncated. Get a Pango-friendly
name by converting a LOGFONT to a Pango font description and
getting the name from the font description.
Altered TR's random arithmetic testing to generate single-flonums and very small flonums; fails now because of erroneous types
Fixes to sgn, sinh, cosh, and tanh:
* preserve single-flonum-ness
* correct zero sign (-0.0) for negative return values that are smaller than epsilon
* correct behavior with NaN and infinite inputs
in the bottom window when it really is a different file
(ie, using a same-file predicate that involves opening
the files and comparing the ports)
closes PR 12635 (hopefully -- if not, then we can reopen)
Caveats:
- keyword function definitions do not define static
bindings, thus limiting optimization opportunities
- can't use `define:`, `lambda:`, etc with keywords
- error messages sometimes expose the implementation
- the optimizer skips most of the generated code for
keyword functions definitions (user-level code is
optimized)
This reverts commit fc8cb6e37d.
Jay changed the set of installed font packages on DrDr to match the
ones on my linux VM which brought the test results back in sync again,
so we don't need these revised bitmaps anymore.
Thanks, Jay!
Also, fix FFI procedures to preserve names: change `ptr-ref' with
`_fpointer' on an `ffi-obj' value to return the `ffi-obj'
value, so that the name in the `ffi-obj' value can be used
by `_cprocedure'.
Closes PR 12645
Previously, some hacks were used to obtain the internal
identifiers that implemented keyword functions directly, and
give them types at startup. Now, the primary "function"
(eg, `sort`) is given a type, and when used, the residual
syntax properties are used to find `sort` from the real
functions, and then the type of the real function is computed
from the type of `sort`.
Some creativity was required in the types of functions which
take optional arguments that when present, alter the return type,
such as `regexp-match*` and `file->list`.
Specifically:
- make predicate symbols and variables be original (and,
in the former case, have srclocs)
- remove the originality in the quoted syntax constants
that the expansion introduces
I think there is probably something better that should be done
with those introduced syntax constants, possibly relacing
them with #f, or possibly replacing them with source location
lists, but I'm not sure how they are used, so I've just left
them in there.
(Also, very minor Rackety in check syntax)
the error raising code, except in one place where I think the
error raising code was correct to have the plural form, so I changed
it back instead of changing the Redex test suite to match
like textual-read-eval-print-loop
There is still a difference, however, because drracket's REPL has a
notion of multiple expressions that are submitted simultaneously that
textual-read-eval-print-loop doesn't. For example, if you type this at
the prompt:
(car) (+ 1 2)
then textual-read-eval-print-loop will print out the error and then 3,
but drracket will print only the error (ditto if (car) were replaced
by a continuation abort).
This difference is, IMO, a good thing, since it lets you use a single
interaction to do multiple things, but stops as soon as there is an
error. (It is also how drracket has behaved for a long time.)
closes PR 12790
There was an exception raised and then handled internally when the
slideshow/pict-convert library was loaded; DrRacket loaded this
library during the dynamic-extent of a handler it installed into
the global-port-print-handler, which causes a (non-tail) infinite
loop.
New vector-of-component functions: unsafe-flomap-ref*, flomap-ref*, flomap-bilinear-ref*, build-flomap*, inline-build-flomap*;
REPL interaction with -ref* is a bit weird - still need to make flvectors print nicely
Bilinear ref and scaling fix on top and left borders (bad/missing special cases);
Clarified flomap-bilinear-ref docs on extent of interpolated nonzero rectangle
Various doc fixes
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.
A common Slideshow pattern is to put a subset of slides in its
own module with a `run-slides' function, and then you'd
(un)comment a `(run-slides)' call at the end of the module to
work on the subset by itself. Now, you can write
`(module+ main (run-slides))' atthe end of the module and not
have to comment it out. Adding `main' support to the `slideshow'
executable makes it more consistent with using `racket' directly.
Checking first for a `slideshow' submodule makes it possible
for `slideshow' and `racket' to do different things, in case
that's useful.
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.
This change does not yet update the *SL error-message rewriter
to recognize the new error-message formats; the tests do not
currently use the rewriter. A next step is to decide on the
rewritings, implement them, change the test suite to use the
rewriter, and test the rewritings.
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.
This makes it more efficient to plot piecewise functions by drawing each piece with one renderer, and possible to plot functions with discontinuities by using a renderer to draw each continuous piece.
