@greghendershott greghendershott Use Racket lexer for code blocks.
Had been specifying Scheme lexer for code blocks, while waiting for
new Racket lexer to wend its way from Pygments to Pygments.rb to
Linguist to GitHub.

That day is almost here: Linguist will soon update and deploy to
GitHub.  And Racket 5.3.2 is about to release.  As a result, I think
this is the correct time to switch to the Racket lexer: It should be
live on GitHub by the time people are using Racket 5.3.2.

/cc @rmculpepper -- I think this commit should go into the 5.3.2
release.

@mflatt mflatt futures: bug fix
The problem was in the handing of "lightweight continuations" used to
represent suspended computations, and in particular the handling
of continuation marks (such as the ones added by DrRacket's debugging
mode).

Unfortunately, I wasn't able to construct a simpler test case that
triggers the problem. I think the number of installed continuation marks
has to be just right, and there have to be some replacing marks, and
a lightweight continuaiton has to be captured at the right time
as a result of applying a previously captured continuation.

@elibarzilay elibarzilay Do the conventional DMG layout.
Note that this requires a running Finder.  Note also that the process
involves attaching the created DMG which means that it might be
problematic with a machine that might have a volume by the same name
already attached (since the applescript uses the volume name, which is
not required to be unique).

@elibarzilay elibarzilay Saner dmg code organization.
"dmg" is now the layout-enabled usual DMGs, since they will soon have
more functionality around them (signed applications).  "sdmg" is for the
simple (or "source") DMGs, which are just plain containers for a
directory.  Also use a flag to avoid the stupid dynamic scope hack.

@elibarzilay elibarzilay Lots of improvements to DMG creation.
* Remove lots of sudoing, and instead use one to change the contents (of
  non-simple DMGs).  Perhaps that's not needed too.  (I think that there
  used to be some problem when the owner was a specific user in the
  installer script days, perhaps it caused some mess in the pre/post
  flight scripts.  Maybe it's safe to not do this anymore.)

* There was a fundamental weakness in the Finder script -- it tweaks the
  DMG by openning its mount, but the way to specify a disk is via its
  displayed name which is not unique.  This can be problematic if there
  is already a mount that has the same name, and given that the DMG
  machine can be used by PLT people, it's even likely to happen.  It is
  tricky to solve this, since there is no way that I see to refer to the
  disk by its mount point or device in the Finder, and no way to find
  out the name in the shell.

  I spent a ton of time searching the webs for a solution, but it seems
  that practically nobody is concerned (or even aware of this problem).
  Eventually, the hack I did is to mount the image onto a randomly named
  directory, then iterate over all disks and look for one whose `name'
  property is that directory name (apparently the `name' property is the
  name of the last component of the mount point).  For safety, throw an
  error if no such disk is found, or if more than one is found.

  Incidentally, using a known mount point also simplifies things since
  there is no need to know the device name of the mount.

* Use UDBZ instead of UDZO for the compressed image.  The savings are
  not as big as I expected them to be for some reason, but the
  compatibility issues should be all gone now (UDBZ works only from 10.4
  and up).

* Unset $LD_LIBRARY_PATH to avoid some 10.8 bug.

* Switch the build to happen on dublin, running 10.8.  At least
  code-signing is broken on the 10.5.8 machine, and possibly also the
  osascript to identify the desired image disk.

Neil Toronto Made arrays strict by default; please merge to release
* Added parameter `array-strictness', default #t

* Added `array-default-strict!' and `array-default-strict', which act

  `array-strictness' is #t; otherwise they do nothing

* Lots of small changes to existing array functions, mostly to ensure
  computations are done using nonstrict arrays, but return values are
  strict when `array-strictness' is #t

* Added strictness tests

* Added tests to ensure untyped code can use `math/array'

* Rewrote `array-map' exported to untyped code using untyped Racket

* Rearranged a lot of `math/array' documentation

Neil Toronto Fixed major performance issue with matrix arithmetic; please merge to…
… 5.3.2

The fix consists of three parts:

1. Rewriting `inline-matrix*'. The material change here is that the
   expansion now contains only direct applications of `+' and `*'.
   TR's optimizer replaces them with `unsafe-fx+' and `unsafe-fx*',
   which keeps intermediate flonum values from being boxed.

2. Making the types of all functions that operate on (Matrix Number)
   values more precise. Now TR can prove that matrix operations preserve
   inexactness. For example, matrix-conjugate : (Matrix Flonum) ->
   (Matrix Flonum) and three other cases for Real, Float-Complex, and
   Number.

3. Changing the return types of some functions that used to return
   things like (Matrix (U A 0)). Now that we worry about preserving
   inexactness, we can't have `matrix-upper-triangle' always return a
   matrix that contains exact zeros. It now accepts an optional `zero'
   argument of type A.

@rfindler rfindler only when when there is something to undo
They hypothesis behind this change is that the undo is
undoing an edit that came before, not the temporary edit
that appears in insert-close-paren. So, when there are
no edits happening (ie when fixup? is #f) then don't
undo. This is only a hypothesis because we were not able
to find a small code sequence, outside of DrRacket to
cause the bad behavior, so possibly there is really more
going on here.

Thanks to Nadeem Abdul Hamid for finding this fix.

even if a later expansion fails. So there are two sets of

@mflatt mflatt fix bytecode compiler safefor-space, tigher bytecode validation
The safe-for-space pass could add clearing operations on "typed"
stack positions, which are known to contain a fixnum, flonum, or
extflonum. Non-clearing references, however, were not annotated to
indicate that clearing references were present, since clearing is
not expected on typed positions.

Along the lines of not expecting clearing, the bytecode validator's
encoding of the stack doesn't accomodate both "has a type" and "claims
never to be cleared", so it couldn't detect the bytecode compiler
bug. (Also, this problem didn't show up in the HOSC paper's model of
the validator, because the model pre-dates type tracking.)

Fix the bytecode compiler's space-safety pass so that it never inserts
clearing operations for typed stack positions. Then, the validator can
simply reject any attempt to clear a typed position.

Also, annotate applications generated by lifting as safe-for-space
tail calls.

@samth samth Refactor subtype.rkt not to use exceptions.
Matthew suggests that using exceptions for failure
in the implementation of `subtype` is a performance
problem.  This commit removes all use of exceptions
for failure in subtype.rkt, replacing it with the
standard Racket #f/value option.

Extensive use is made of the `subtype-seq` form,
which is basically do-notation for the subtyping
monad.

This repair omits one part of the original commit,
which is the `gc->dumping_avoid_collection' test
