They need to be encoded in the same way that strings are
encoded. (Report and fixed by Phil Roberts.)
Also added a FIXME about leftover occurrences of \U in the output.
Closes PR 13966.
but this also means that multi-column cells can
refer to variables in the column header (ditto
for multi-row cells)
the code duplication can be fixed with a little
more smarts at the match level, I believe
(see comment in source)
Loading "info.rkt" files always from source turns out to be
expensive (adding 1 second or so on my machine to the startup
time for `raco setup'). Change bootstrap mode to try the compiled
form and fall back to source if its doesn't work.
Separate state and functions, and convert a key loop to functional
style. As it turns out, this has no significant effect on performance,
but it looks a lot better to me.
Make the stack-safety margin twice as big for 64-bit platforms
as 32-bit platforms. That was already done for Windows, but it's
also needed for Mac OS X. Also, double-check that there's a
good amount of space on the stack before calling a foreign
function.
There was an off-by-one error in trimming overflow
records in a captured continuation.
I provoked the crash by running the program below on Mac OS X;
resizing the frame caused a crash. It has something to do with the
`try-atomic' implementation, I think. I wasn't able to make a test
case in a half-hour of trying, however, and I'm giving up for now.
(define f (new frame% [label "deep"]))
(define b (new button%
[parent f]
[label "0"]))
(send f show #t)
(let loop ([n 0] [m 0])
(if (= n 10000)
(begin
(send b set-label (format "~a" m))
(for ([i 10]) (yield))
(loop 0 (add1 m)))
(cons 1 (loop (add1 n) m))))
Bootstrap mode disables the use of a compiled form of "info.rkt",
in case the compiled form is broken. It also attaches `info'-language
modules from the `setup/getinfo' namespace to the "info.rkt"-loading
namespace.
Formerly, `raco setup' relied on capturing the bytecode-compilation
bootstrap context used for `raco setup' itself when loading info
files. But when `raco pkg install' used `raco setup', it didn't have
the same bootstrapping context in place, so it could get confused
(e.g., if you unlink a package from one Racket version and install it
as a link in a different Racket version). Now, both `raco setup' and
`raco pkg' use `#:bootstrap?' mode for `get-info/full'.
These comparisons are useful for sorting while avoiding the overhead
of conversions to bytes or strings.
Having `path<' reduces the cost of sorting in `directory-list'.
Consistently sorting shouldn't cost much relative to the
cost of `directory-list' (except for the path->bytes conversion?),
and it makes directory traversals (including archive packaging)
more deterministic across runs and platforms.
(Eli suggested this a long time ago.)
