| 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 |
