Red Hat Linux 9 Release Notes

Copyright © 2003 Red Hat, Inc.

#

Red Hat Linux 9 includes the Native POSIX Thread Library (NPTL), a new 
implementation of POSIX threads for Linux. This library provides performance 
improvements and increased scalability for i686 or better processors.

This thread library is designed to be binary compatible with the old 
LinuxThreads implementation; however, applications that rely on the places 
where the LinuxThreads implementation deviates from the POSIX standard will 
need to be fixed. Notable differences include:

- - Signal handling has changed from per-thread signal handling to POSIX process 
signal handling.

- - getpid() returns the same value in all threads.

- - Thread handlers registered with pthread_atfork are not run if vfork() is 
used â?? no manager thread

Applications that are known to have problems using NPTL include:

- - Sun JRE prior to version 1.4.1

- - IBM JRE

If an application does not work properly with NPTL, it can be run using the 
old LinuxThreads implementation by setting the following environment 
variable:

LD_ASSUME_KERNEL=<kernel-version>

The following versions are available:

- - 2.4.1 â?? Linuxthreads with floating stacks

- - 2.2.5 â?? Linuxthreads without floating stacks

NPTL support for all dynamically-linked applications can be disabled by using 
the following boot-time option:

nosysinfo
#

A new system message has been added to Red Hat Linux 9:

application bug: <app-name>(<app-pid>) has SIGCHLD set to SIG_IGN but calls 
wait(). (see the NOTES section of 'man 2 wait'). Workaround activated.

This message (which is displayed on the system console and/or in the system 
log files) indicates that the application is not completely standards 
compliant with respect to its handling of child processes. If you see this 
message, you should alert the application's developers.
#

Kernel Notes

This section covers issues that are related to the Red Hat Linux 9 kernel.
...
The kernel support for the new NPTL feature changes several internal kernel 
programming interfaces significantly. As a result, several external kernel 
modules may not compile without modifications to match the new interfaces. 
Examples currently include the NVIDIA and ATI 3D modules, as well as any 
other modules that use kernel threads and/or signals.

Kazval sum go i drug put v list-a - RedHat kernel e customized kernel.
Ako iskash da go polzvash vse pak ste trjabva da si rebuild-nesh i 
prilozeniata (ot citiranoto po-gore si pravja izvoda, che za njakoi 
prilozenia tova njama da e trivialna zadacha)
