58e15cc2c7 fix tests for the "class:"-less object-name results 2012-12-22 18:25:43 -06:00

b112a7ef0a adjust object-name on classes and interfaces to drop the prefix 
Before this commit, things like this:

  (define c% (class object% (super-new)))
  (object-name c%)

would produce

   'class:c%

but now classes and interfaces will be more like procedures and, in
the example above, just produce:

   'c%

The underlying goal is to make error messages generated from contracts
like

  (is-a?/c frame%)

have "(is-a?/c frame%)" in the message, instead of "(is-a?/c
class:frame%)"

a09c8f1857 Revert "racket/draw: fix another problem with the JPEG binding" 
This reverts commit c2468f1f9a.

The libjpeg documentation claims that it has no static state,
so atomic mode shouldn't be necessary. Also, the stress test is
still failing on some platforms, so there must be a different
problem than I thought.

1aebd171c5 Moar matrix review/refactoring 
* Consolidated Gauss and Gauss-Jordan elimination

* Fixed Gaussian elimination to return all indexes for pivotless columns,
  not just those < m

* Consolidated `matrix-row-echelon' and `matrix-reduced-row-echelon'

* Specialized row reduction for determinants; removed option to not do
  partial pivoting (it's never necessary otherwise)

* Added `matrix-invertible?'

* Removed `matrix-solve-many'; now `matrix-solve' solves for multiple
  columns

* Gave `matrix-inverse' and `matrix-solve' optional failure thunk arguments

* Made some functions that return multiple columns return arrays instead
  (i.e. `matrix-column-space')

* Added more tests

fdd9344b27 adjust file to use the literal bytes for the ufo image 
this may not be suitable code for RoR, I'm not sure, but it
avoids the compilation problem and was fun to try out
(at least for me)

200ec130a0 drracket's online compilation now tracks files loaded during expansion 
use these files to determine if a file is dirty (and thus needs
to be recompiled) when another file is saved.

5259f159af planet2: include the Racket version number in a PNR request 
The version number is included as the query part of the constructed
URL, so it is easily ignored by a server. The intent is that the
PLT PNRs will eventually support version-specific results.

3fb02ecb2e mingw32: use same strategy for thread-locals as MSVC 
The gcc implementation of `_thread' seems to be much
slower, so we use the inline-assembly technique from
the MSVC build plus a hack in "main.c".
