in subdirectory and need to execute setup.py in that directory, but
still need WRKSRC set to the base directory for configure/patch targets
to handle this, add PYSETUPSUBDIR variable (default empty), and
change do-build+do-install targets to use working directory
${WRKSRC}/${PYSETUPSUBDIR} when executing setup.py
So we get native threads on -current in the default case.
The stacksize bug is still annoying. To survive the selftests, we'd
have to limit the recursion depth to 13. But then, people trying the
first recursive function would be disappointed if they can't even
calculate fac(15)...
Otoh, add-ons like py-gtk and py-wxwindows pull in dynamic libraries
which require libpthread, so we have to cope with it somehow.
In short, OOC is an Internet based project providing an Oberon-2
development platform. It consists of
* an optimizing compiler,
* a number of source code and compiler related tools,
* a set of standard library modules, and
* a reference manual.
oo2c is the first complete working compiler of the OOC project.
Instead of translating Oberon-2 modules to machine code, it generates
code for the most portable assembler in existence: ANSI-C. The
compiler was initially intended as a prototype backend for OOC, which
could then be used to evaluate and debug the frontend and the
optimization modules. However, it is now a full-fledged development
system, and among other things, it is being used to develop native
code OOC backends.
with some minor modifications by me.
Yabasic implements the most common and simple elements of the basic language;
It comes with goto/gosub, with various loops, with user defined subroutines
and Libraries. Yabasic does monochrome line graphics and printing.
Yabasic runs under Unix and Windows; it is small (around 200KB) and free.
Changes to the Mercury language:
* Support for constrained polymorphic modes.
* Addition of state variable syntax.
* Improved support for higher-order functions.
* Predicate and function equivalence type and mode declarations.
* Support for defining predicates or functions
using different clauses for different modes.
* Support for Haskell-like "@" expressions.
* Generalized foreign language interface.
Changes to the Mercury compiler:
* A new `--make' option, for simpler building of programs.
* A new `--smart-recompilation' option, for fine-grained dependency tracking.
* A new optional warning: `--warn-non-tail-recursion'.
* A new optimization: `--constraint-propagation'.
* A new optimization: `--loop-invariants'.
* Support for arbitrary mappings from module name to source file name.
Portability improvements:
* Mac OS X is now supported "out-of-the-box".
* On Windows we now support generating non-Cygwin executables.
* Better conformance to ANSI/ISO C.
Changes to the compiler back-ends:
* The native code Linux/x86 back-end is now "release quality".
* The .NET CLR back-end is much improved.
Major improvements to the Mercury debugger, including:
* Support for source-linked debugging using vim (rather than emacs).
* Command-line completion.
* Ability to display values of higher-order terms.
* Declarative debugging.
* Support for transparent retries across I/O.
A new profiler, which we call the Mercury deep profiler or mdprof:
* Supports both time and memory profiling.
* Gathers information about individual call sites as well as procedures.
* Eliminates the assumption that all calls to a procedure have equal cost.
* Allows users to explore the gathered data interactively with a web browser.
Numerous minor improvements to the Mercury standard library.
A new testing tool in the extras distribution.
Changes since 13-1.0.7:
- A de-serialized GregorianCalendar did not correctly handle the
Calendar.set(int field, int value) method.
- Java Plug-in Security Warning dialog did not show buttons.
- java.beans.Introspector returned results depending on the order
that classes were loaded by the Virtual Machine.
- A help viewer search would sometimes yield NullPointerExceptions,
and search hit highlighting was unstable.
- The "~" character was not properly displayed in an HTML file
using the SJIS character set.
- There was a system crash generating a Fatal: unhandled ci exception.
- Plugin regional locale parameters were incorrectly displayed.
- The VM crashed while running a large application.
- An application ignored the nohup(1) command, caught and processed
the SIGHUP signal, resulting in application exit with a return code
of 129.
- In some cases, the text field caret did not return when window
focus was moved and then restored.
- SIGSEGV during C2 compilation of a method.
- System crashed with hotspot errors.
- Plug-in crashed when the ethernet cable was unplugged.
- Signed applet failed only on JRE 1.3.1_06.
- System crashed when attempting to widen the range check of an IF
node during compilation.
- The background color of a Menu was different from that of the
MenuBar for classic style.
- Application crashed due to problems in JVM/plug-in/Mozilla.
- Serviceability is improved by exposing VM version and flags to
Serviceability Agent.
- Double primitive lost value when using -client.
- White background persisted when applet exited to a different web
page.
- An applet could access a local resource without permission on
IE60+JRE1.3.1_06.
Erlang is a programming language which has many features more commonly
associated with an operating system than with a programming language:
concurrent processes, scheduling, memory management, distribution,
networking, etc.
The initial open-source Erlang release contains the implementation of
Erlang, as well as a large part of Ericsson's middleware for building
distributed high-availability systems.
* Changes from version 4.0 to 5.0
-------------------------------
Language:
+ lexical scoping.
+ Lua coroutines.
+ standard libraries now packaged in tables.
+ tags replaced by metatables and tag methods replaced by metamethods,
stored in metatables.
+ proper tail calls.
+ each function can have its own global table, which can be shared.
+ new __newindex metamethod, called when we insert a new key into a table.
+ new block comments: --[[ ... ]].
+ new generic for.
+ new weak tables.
+ new boolean type.
+ new syntax "local function".
+ (f()) returns the first value returned by f.
+ {f()} fills a table with all values returned by f.
+ \n ignored in [[\n .
+ fixed and-or priorities.
+ more general syntax for function definition (e.g. function a.x.y:f()...end).
+ more general syntax for function calls (e.g. (print or write)(9)).
+ new functions (time/date, tmpfile, unpack, require, load*, etc.).
API:
+ chunks are loaded by using lua_load; new luaL_loadfile and luaL_loadbuffer.
+ introduced lightweight userdata, a simple "void*" without a metatable.
+ new error handling protocol: the core no longer prints error messages;
all errors are reported to the caller on the stack.
+ new lua_atpanic for host cleanup.
+ new, signal-safe, hook scheme.
Implementation:
+ new license: MIT.
+ new, faster, register-based virtual machine.
+ support for external multithreading and coroutines.
+ new and consistent error message format.
+ the core no longer needs "stdio.h" for anything (except for a single
use of sprintf to convert numbers to strings).
+ lua.c now runs the environment variable LUA_INIT, if present. It can
be "@filename", to run a file, or the chunk itself.
+ support for user extensions in lua.c.
sample implementation given for command line editing.
+ new dynamic loading library, active by default on several platforms.
+ safe garbage-collector metamethods.
+ precompiled bytecodes checked for integrity (secure binary dostring).
+ strings are fully aligned.
+ position capture in string.find.
+ read('*l') can read lines with embedded zeros.
Lua is a powerful, light-weight programming language designed for
extending applications. Lua is also frequently used as a
general-purpose, stand-alone language.
GHC documentation for details.
The most import change is that this package (which has been broken since the
conversion from a.out to ELF) has been re-ported to NetBSD by Urban Boquist,
boquist@crt.se.
