Short: IXemul 45.1 - 68020 library
Author: various
Uploader: fnf@ninemoons.com
Type: dev/gcc
This is ixemul.library release 45.1, a shared library that makes it possible
to compile and run most Unix programs under AmigaOS with almost no changes.
IXemul is part of the ADE (Amiga Developer's Environment), a community
effort to produce a complete development environment that is stable,
available in source, and completely self-hosting. See the ADE readme file
at ftp://ftp.ninemoons.com/pub/ade/README for more details about ADE.
As of version 43.1, IXemul includes Jeff Shepherd's networking code. If
ixnet.library (included) is installed then ixemul.library will use the
networking functions from the ixnet.library, instead of the default dummy
implementation. Ixnet.library works with AS225 and with AmiTCP. It
supports both clients and daemons. A program that uses networking functions
is completely shielded from the AS225 and AmiTCP differences by
ixnet.library, which will take care of all the details for you. That means
that there is no longer any need to provide two different binaries, one for
AS225 and one for AmiTCP. Furthermore, it is relatively easy to add support
for other network packages.
The following are the changes made since the 45.0 release:
Fixed a bug in the Unix Domain socket code that would
occasionally cause a client to wait indefinately for a
connection to be granted, while in fact the server had
already accepted the connection.
getdtablesize() now returns FD_SETSIZE instead of NOFILE
(256 instead of 512). The result of this function was used
by several X clients to discover the number of filehandles
select() can test. And if that value is to large, you'll get
unexpected and hard to find crashes. The same change was
made to sysconf(_SC_OPEN_MAX).
shutdown() could close down the whole Unix domain socket,
causing a crash when the socket was closed a second time by
the 'real' close.
rename() now tests for a rename across devices and returns
the correct error code.
Applied patch from Norbert Pueschel to improve delayed
unlink.
Closing of Unix domain sockets is now atomic (between
Forbid/Permit), otherwise the Amiga could crash if the X
server was running at a higher priority than the client.
Fixed a bug in ixemul.trace that caused Enforcer hits in
gcc.
Fixed a bug with 'du -ks /volume'. The convert_dir()
function stored the directory name in Amiga format instead
of Unix format.
Norbert Pueschel greatly improved uid/gid handling in
ixemul.library. See the README for detailed information.
Fixed a bug in handling volumes/devices named "dev:". Ixemul
handles the volume /dev specially (e.g., /dev/console is
translated to console:) and that interfered with the
handling of the DEV: device or any volume named DEV:. To
circumvent the /dev handling you can now use "dev:" instead
of "/dev" or write "DEV" instead of "dev" (in other words,
the open() function tests for the string "/dev/" in a
case-sensitive way).
Due to a clumsy design of the ENV: notification a signal was
occasionally left unfreed. WShell gives warnings for that,
so I changed the design and that should take care of the
warning. The unfreed signal warning was harmless, but
annoying.
Now fill the file type in the dirent struct. Thanks to Lars
Hecking for reporting this.
Some AmigaOS programs started from an ixemul program set
Signals that were allocated by ixemul. This can happen
because ixemul resets the allocated signal mask in the Task
structure. Because of that a handshake between the child
and the parent when the child process is dying failed, and
Enforcer hits (usually followed by a crash) were the result.
Fixed by resetting all Signals.
Fixed a bug in the trap.s supervisor() code: you cannot
safely pass data on the stack to the function to be executed
in supervisor mode. In fact, this failed with a beta version
of the 68060.library from Phase 5. Now pass the data through
registers.
Fixed bug in frexp(0.0, &i) where i was set to 1 instead of
0.
Fixed 32 Kb memory leak.
Added tty CRMOD support.
Fixed serious bug in unix domain sockets where a kind of
deadlock situation could occur.
system() now searches the whole path for 'sh' and doesn't
use /bin/sh only. Also the paths in paths.h have been
ADE-dified. Thanks to Robert Davis for pointing out the
system() problem.
select() on a small file that was stored in memory if the
user selected a non-zero Membuf size in ixprefs didn't
produce the expected results. Thanks to Stefan Grosse Pawig
for reporting this.
The net ixemul library distribution consists of several archives:
ixemul-bin.lha Utils for gnu/bin, like ixtrace and ixconfig
ixemul-sdk.lha Files needed to build applications that use
ixemul.library.
ixemul-doc.lha Various documentation, such as this file
ixemul-src.lha Complete source code for ixemul library
ixemul-tz.lha Pieces for doing TZ (timezone) management
ixemul-CCCF.lha Specific flavors of the library, where 'CCC'
is one of 000, 020, 030, or 040, for 68000, 68020,
68030, and 68040 respectively, and 'F' is either
'f', 's', or 't' for FPU support or soft floating
point or a "trace" version (also soft float)
respectively.
For further information consult the NEWS, INSTALL, README and TODO files in
the documentation archive.
