This should have been like this all along; I think it can lead to
race-conditions with high-priority events. In particular, something
might be pending in the event queue and then the test suite might
queue a high-priority event to check for it, which could happen before
the event that actually does the work that's being checked for!
When libmpfr wasn't available, the function created by `make-not-available'
would try to print any _mpfr arguments, which would call the custom _mpfr
printer, which would try to use a libmpfr function, which would call the
function created by `make-not-available', which would try to print...
The px unit is a pdflatex specific adjustable unit that is 1 bp (big
point = 1/72in) by default. This commit changes the latex renderer to
use bp which is a standard TeX unit equivalent to the default px
value. This change allows .tex files generated by scribble to work
with other latex engines such as xelatex.

Here is a small test of using scribble and xelatex:
$ cat try.scrbl
@(require scriblib/figure redex/reduction-semantics redex/pict)
@(define-language L)
@(render-term L (term 1))
$ scribble --latex try.scrbl ; xelatex try
Cleaned up expected value code a little
Refactored running statistics objects (hid private fields, added
`update-statistics*')
Documented expected value functions and running statistics
Removed `bfpsi0' from bigfloat tests (DrDr's libmpfr doesn't have it)
Commented out custodian shutdown callback that frees MPFR's cache
(something's broken)
of libmpfr (like DrDr's) that don't have it
Reimplemented really simple FFI functions (e.g. mpfr-prec, mpfr-exp) to
avoid calling overhead
Renamed `bigfloat-sign' to `bigfloat-signbit'
Renamed `bigfloat-sig+exp' to `bigfloat->sig+exp' (for symmetry with
`sig+exp->bigfloat')
use longs for the "limbs" of bigints. However, when GMP's configure script
detects that mingw64 is compiling, it defines LONG_LONG_LIMB, which makes the
type of limbs long long, or 64 bits. This is fine; a 64-bit machine should use
64-bit ints for the digits of its bigints. It would have been nice to know
this special case earlier, though I can see why it's not advertised: most
users don't need to know, and it seems like it's obviously the right choice to
make when dealing with Win64's annoying ABI.
Made "mpfr.rkt" search for 'mpfr_set_z_exp if 'mpfr_set_z_2exp isn't found.
Hopefully this allows the bigfloat tests to finish on DrDr. If not, DrDr
will need a libmpfr upgrade.
Made some minor doc fixups
Exact 0 turns out to also be a corner case for addition.
At this point, mixed-mode optimizations pretty much only apply for mixes
of floats and literal non-zero non-floats.
Fixed bigfloat functions that assumed (fixnum? x) means x fits in a _long
(not true on Win64)
Hopefully fixed dangling pointer errors that broke `math/bigfloat' on Win64.
It apparently had no _long/_int mismatches, but GC on Win64 will run between
creating an `_mpz' and using its value after passing it as an output argument
to MPFR functions. That doesn't seem to happen on 64-bit Linux or Mac. No
idea why, but Win64 exposed the problem so... that's good, I guess.
Rewrote `rational->bigfloat' to not use GMP's rationals
More/better bigfloat tests
Added bigfloat stress test w/ weak leak detection
Reenabled custodian shutdown callback that clears MPFR constants, because it
seems to work now
Removed `mpfr-available?' because it would only return non-#f
Note: this isn't the ideal location for this in the long
run because it isn't a special form. When we have more
bindings like this, we should move them to a new manual
section.
Allowing them would require support for immutable fxvectors and
flvectors, interning, and more. Since the motivation for reader
support is to make marshaling and unmarshaling easier, allow
them only in `read' mode. Change printing to make then unquotable.
More generally, a `splicing-syntax-parameterize' wrapping immediate
compile-time code effectively parameterizes the compile-time code as
well as any macro-triggered compile-time code. This is implemented by
using a compile-time parameter that complements each syntax binding.
Use `raise-user-error' for `raco pkg ...' errors, so that stack
traces don't print out for external errors. Reformat error messages
generally to match current conventions. Use logging for debugging
output.
The default `raco pkg' mode should work right for a
multiple-version installation (because everything in
Racket should work in a multiple-version installation).
Along the same lines, `raco pkg' should work if the
installation directory is unwriteable. So, the default
mode is user-specific and version-specific.
Use `--shared' or `-s' for user-specific, all-version
installs.
By default, `raco pkg show' now shows packages installed
in all three modes (installation-wide, user- and version-
specific, and user-specific all-version). Use `-i', `-u',
or `-s' to show just one of them.
For now, "METADATA.rktd" is still recognized as a fallback.
Also, rewrite package source type and name inference,
make ".zip" the default format for `raco pkg create',
and many doc edits.
Now works with the handler argument omitted, in which case
the default handler is used. Note that the default handler
cannot be used in conjunction with the default prompt tag
because it is unsound to do so.
Reset result is from last step; looking at it was probably causing
spurious failures and busy-timeouts.
Transaction completion relies on statements being reset reliably.
original array strict instead of returning a new strict array.
(Finally!) The hard part is keeping the Array type covariant. The
solution is to keep the store in the closure of the array's
procedure instead of in the Array struct itself.
