Changes in Racket 5.1.3
This is a bugfix release, resolving the DrRacket issue with
the contour view. In addition, two tex files with problematic
licensing were removed.
Changes in Racket 5.1.2
* The download page includes 64-bit installers for Mac OS X,
Windows, and two Debian flavors. Racket now supports OS X Lion.
* Racket now includes a new `racket/place' library to support
parallelism, complementing `racket/future'. Racket's parallel
build process is now based on places instead of multiple OS
processes.
Places support share-nothing parallelism and message-passing
communication. Compared to futures, places are heavyweight, but
they have a simpler performance model.
* The syntax-certificate system has been replaced by a syntax-taint
system. Both certificates and taints were designed to protect
otherwise inaccessible bindings from abuse when they appear in
macro expansions. Taints are simpler and lighter, and the switch
closes known holes in the certificate system. Macros that are not
implemented with `syntax-rules' or `define-syntax-rule', however,
must explicitly use `syntax-protect' to protect their expansions
from abuse.
* The `net/url' library supports HTTPS connections, but beware that
by default all sites are accepted (equivalent to ignoring a
browser's warnings about untrusted certificates).
* Error messages in the student languages use a simplified
vocabulary and consistent phrasings. If you maintain curriculum
material or teachpacks then please consider updating. See the
"Error Message Composition Guidelines" section in the
documentation for details.
* Typed Racket: almost all core Racket data structures and
operations are now accessible in Typed Racket (most of this work
is due to prolific contributor Eric Dobson). The performance of
the typechecker has been significantly improved.
* The `scriblib/bibtex' library supports BibTeX-formatted citation
databases in Scribble documents. BibTeX can be tricky to parse,
so please report failed entries as bug reports.
* The `for' forms now support an `#:unless' clause, and a
nonnegative integer can be used as a sequence. The new `compose1'
function creates single-valued composition functions. The
`racket/function' library now provides `identity', `thunk', and
`thunk*'.
* The license has been clarified: we now use LGPLv2.1 uniformly.
(The license file used to specify LGPLv2, contrary to the download
pages.)

What's Changed From p180 to p290?
Quite a lot got changed in terms of the numbers. 132 files were
tweaked with a total of 3505 lines added and 788 taken away.
A selection of the fixes:
* require 'date'; Date.new === nil throws an undefined method error for
coerce on p180 - this has now been fixed
* The Thread.kill segfaults when the object to be killed isn't a thread bug
has been resolved.
* Tweaks to reduce segmentation faults when using zlib on x86-64 Darwin
(OS X) - always good
* Modification to prevent random number sequence repetition on forked child
processes in SecureRandom
* Fix to io system to resolve a Windows-only bug where characters are being
read incorrectly due to ASCII not being treated as 7 bit
* A tweak to Psych (the YAML parser) to plug a memory leak
* Load paths are now always expanded by rb_et_expanded_load_path (I think
this might yield a performance gain?)
* Fixes to Psych's treatment and testing of string taint
* Prevention of temporary objects being garbage collected in some cases
* Fixes to resolve compilation problems with Visual C++ 2010
* A fix so that Tk's extconf.rb would run successfully
* Lots of Tk related fixes generally - I'm guessing Tk is very popular
amongst the core team, particularly in Japan, because it seems to be a
common release blocker.
* A fix to string parsing to resolve an obscure symbol-containing-newlines
parsing bug
If it specified, it modify gemspec's dependency using update-gemspec.rb
Ruby script.
The goal is avoid to use patch for modifying depending version or gem's
name since gemspec files' content differ using rubygem's version.
move PKGREVISION to each Makefile including the Makefile.common for
keep version number, and bump again for ocaml-graphics because the
previous bump resuited in downgrade.
* Several modules were updated to fix minor bugs.
* Tests were fixed.
* Documentation was improved.
Changes 5.14.0:
* Unicode version 6.0 is now supported.
* Regular expressions can now be reset to the default modifiers.
* Four new regular expression modifiers, "/d", "/l" , "/u", and "/a", were
introduced.
* The substitution operators now support the modifier "/r" to work
non-destructively, leaving the original unmodified.
* Larger octals can now be specified.
* Array and hash operators can now experimentally operate directly on hard
references.
* printf-like functions now understand post-1980 size modifiers.
* Exception handling was made more reliable and consistent.
* Other enhancements and many bug fixes were made
PkgSrc:
* Fixed configuring on Mac OS X 10.7.
From upstream comment:
nm isn't known to work after Snow Leopard and XCode 4; testing with OS X 10.5
and Xcode 3 shows a working nm, but pretending it doesn't work produces no
problems.
From upstream commit log:
Testing from 10.5 with Xcode 3 to the latest OS X works with usenm='false' but
not always with usenm='true'
Changes in version 5.1.1, May 2011:
Enabled single-precision floats by default
Added single-flonum?
Changed eqv? so that inexacts are equivalent only when they
have the same precision
Changed file-or-directory-permission to add 'bits mode
and permission-setting mode
Added special treatment of void as an 'inferred-name property
Removed the "MrEd" compatability executable under Windows
and Mac OS X, but the "mred" compatibility script remains
racket/gui: added multi-column support to list-box%
racket/gui: added scrollbar support to panel%, vertical-panel%,
and horizontal-panel%
racket/gui: added 'wheel-left and 'wheel-right events
racket/file: add user-read-bit, etc.
racket/contract: removed some (undocumented) exports.
Changes in version 5.1, February 2011
Renamed "proxy" to "impersonator"
Added current-get-interaction-input-port, which enables
racket/gui events to be dispatched while a REPL is blocked
Changed equal? to equate C pointers when they refer to the
same address
Internal: weak boxes are cleared before non-will-like
finalizers; use late-weak boxes to get the old behavior
Changes in version 5.0.2, October 2010
Changed body of `when', `unless', `cond' clauses, `case'
clauses, and `match' clauses to be internal-definition contexts
Swapped unsafe-vector*-ref with unsafe-vector-ref, etc.
Added ->i to the contract library, improved ->*, adding #:pre and
#:post, as well as making the optional arguments clause optional.
Added #true and #false, and changed #t/#T and #f/#F to
require a delimiter afterward
Added print-boolean-long-form
Added read-accept-lang, which is set to #t when
reading a module
Added flonum?
Changed continuation-marks to accept a #f argument
to produce an empty set of marks
Added fxvectors
Added unsafe-{s,u}16-{ref,set!}
Added prop:proxy-of
Added proxies to go with chaperones, and renamed chaperone property
as proxy property; beware that the word "proxy" will change in
a future version, perhaps to "impersonator"
Added collection-file-path and collection splicing at the file
level
Upstream changes:
- Core
+ Parrot_PMC_destroy, Parrot_PMC_mark and Parrot_PMC_invoke were removed from
the public extension API.
+ PAST now has PAST::Stmt node types, supports reusable temporary registers.
+ Test coverage of the embedding and extending interface is now at least 95%.
+ A snapshot of Winxed is now included in Parrot core to facilitate writing
core Parrot tools from a higher level language than PIR.
- Languages
+ Winxed
- Improved compile time scope search.
- Added 'using namespace' statement.
- Compiler classes and functions now live in the Winxed;Compiler namespace.
- Tests
+ The Parrot test suite harness now understands the HARNESS_TIMER
environment variable. Setting it to a true value will show timing results
for a test run.
+ IPv6 tests are now parallel testing friendly.
It was really needed by devel/ruby-railties, sigh.
=== 3.8 / ??
* Minor enhancements
* RDoc::Parser::C can now discover methods on ENV and ARGF.
* RDoc::Parser::C now knows about rb_cSocket and rb_mDL.
* Bug fixes
* Updating Object in an ri data store with new data now removes methods,
includes, constants and aliases.
=== 3.7 / 2011-06-27
* Minor enhancements
* New directive :category: which allows methods to be grouped into sections
more cleanly. See RDoc::Markup for details.
* Document-class for RDoc::Parser::C now supports Foo::CONST as well as
CONST.
* ri method output is now a comma-separated list when displayed
interactively. Pull Request #39 by Benoit Daloze.
* RDoc::ClassModule#merge now prefers the argument's information over the
receiver's (it now behaves like Hash#merge! instead of a backwards
Hash#merge!).
* RDoc::Markup#convert now accepts an RDoc::Markup::Document instance
* RDoc now owns the code for generating RDoc and ri data when gems install
* Added RDoc::RDoc::reset
* Added RDoc::CodeObject#file_name
* Bug fixes
* ri no longer crashes when attempting to complete a plain [.
* ri data now tracks which file information came from so it can process
removals and changes to:
* Classes and Modules
* Methods
* Attributes
* Includes
* Constants
You will need to rebuild your ri data for it to update properly. Issue
#21 by Sven Riedel
* Signal and SignalException no longer clobber each other
* RDoc::Parser::C no longer creates classes when processing aliases.
* RDoc::Text#strip_stars handles Document-method for methods with =, ! and ?
now.
* RDoc::Parser::C now allows .cpp files to be used with the "in" comment on
rb_define_method. Bug #35 by Hanmac.
* RDoc::Parser::Ruby no longer eats content when =begin/=end documentation
blocks are followed by a documentable item. Issue #41 by mfn.
* RDoc::Markup::Formatter and subclasses now allow an optional +markup+
parameter for adding custom markup. The example in
RDoc::Markup::Formatter will now work. Issue #38 by tsilen.
* RDoc::Parser::C can now distinguish between class methods and instance
methods in Document-method. Issue #36 by Vincent Batts.
* RDoc now encodes file names in the output encoding. Issue #33 by Perry
Smith.
* ri data generation for method aliases no longer duplicates the class in
#full_name
Bump pkgrevision.
While I'm here: add a comment to patch-at explaining what it does.
Tested by
$ make install
$ cd work/ocaml-3.12.0/testsuite && gmake one DIR=tests/lib-dynlink-native
(Not in a build-env because that uses the wrappers, which don't let the
test suite see the installed OCaml files.)
This is only a workaround on NetBSD/{i386,amd64} for the problems of
OCaml PR#5049 <http://caml.inria.fr/mantis/view.php?id=5049>. (E.g.,
this workaround makes Coccinelle build on those platforms -- but it
still won't build on platforms with native compilation but no native
dynamic loading. Need to hack everything that uses dynlink to have
four compile-time cases -- {yes,no} {byte,nat}dynlink.)
John Marino per PM
-deal with possibly builtin gmp/mpfr/mpc libs (this is incomplete
for D'fly -- choices are to convert the pre-configure test or
to set USE_BUILTIN.x=no)
This is the list of problem reports (PRs) from GCC's bug tracking
system that are known to be fixed in the 4.5.3 release. This list
might not be complete (that is, it is possible that some PRs that
have been fixed are not listed here):
http://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&resolution=FIXED&target_milestone=4.5.3
On the PowerPC compiler, the altivec builtin functions vec_ld and
vec_st have been modified to generate the Altivec memory instructions
LVX and STVX, even if the -mvsx option is used. In the initial GCC
4.5 release, these builtin functions were changed to generate VSX
memory reference instructions instead of Altivec memory instructions,
but there are differences between the two instructions. If the VSX
instruction set is available, you can now use the new builtin
functions vec_vsx_ld and vec_vsx_st which always generates the VSX
memory instructions.
