* All supported architectures now use the main glibc sysdeps directory
instead of some being in a separate "ports" directory (which was
distributed separately before glibc 2.17).
* The NPTL implementation of POSIX pthreads is no longer an "add-on".
On configurations that support it (all Linux configurations), it's now
used regardless of the --enable-add-ons switch to configure. It is no
longer possible to build such configurations without pthreads support.
Version 2.19

Now that the Linux kernel is once again able to run all the tests we
have and since glibc 2.3 was released it was time for a new code drop.
I've uploaded the second code drop for the Native POSIX Thread
Library:
ftp://people.redhat.com/drepper/nptl/nptl-0.2.tar.bz2
You need
- the latest of Linus' kernel from BitKeeper (or 2.5.41 when it
is released);
- glibc 2.3
- the very latest in tools such as
+ gcc either from the current development branch or the gcc 3.2
from Red Hat Linux 8;
+ binutils preferrably from CVS, from H.J. Lu's latest release for
Linux, or from RHL 8.
Compiling glibc should proceed smoothly. But there are a number of
tests which fail, mostly because some functionality is missing in
glibc. Ignore those errors. It is only important that all tests in
nptl/ are passing. Run
make subdirs=nptl check
to run all thread tests.
This version features several improvements:
- all APIs are now implemented;
- fork handling has been improved; stacks in the child are freed;
atfork handlers are removed if they were registered from a module
which gets unloaded.
- pthread_tryjoin_np and pthread_timedjoin_np are implemented
- TSD handling corrected and optimized.
- many more tests which also test the underlying kernel implementation.
- the build infrastructure has been implemented so that the DSO and
archives are built in usable form and with correct named.
- libthread_db has been implemented. This is the library which is
needed by all program which need to get access to internals of
libpthread (mainly debuggers).
- the CPU clock functions are implemented
The white paper hasn't yet been updated. It's still available at
http://people.redhat.com/drepper/nptl-design.pdf
This release should be ready for some serious testing. I know it is
hard to compile which I why I'm looking into providing binary RPMs.
They can be used on non-critical systems. I'll only be able to
provide binaries for RHL8 based systems, though, and the kernel still
must be installed separately.
The next steps will include:
- write more tests and fix the bugs which are discovered this way
- update the white paper
- write and run more performance tests
- port to IA-64
Interested parties are once again invited to join the mailing we
created:
