parentAdd isilo. (diff)
Update to the most recent release of LinuxThreads, glibc-linuxthreads-2.1.2,
which is rather tightly coupled with GNU libc, unlike the older version of this port. LinuxThreads has added many features since it was integrated with GNU libc, which means that a number of interfaces that were borrowed from libc_r are no longer needed. This updated port required a lot of reworking of the port, so there are likely to be new bugs.

4) Be aware of the following libc issues:
- a) Not all libc calls are thread safe. Many are.
- In particular gmtime, localtime, etc are not thread
- safe. In general, where the pthreads spec calls for "_r"
- functions, these are either not provided, or if provided
- are not thread safe (in most cases) and the related
- libc calls are not thread safe. This differs somewhat
- from the FreeBSD libc_r library, where some, but not
- all, of these functions are both thread safe and have
- "_r" versions.
-
- b) None of the libc calls that are supposed to be
- cancellation points are implemented as such. There
- is a lot of work that needs to be done on libc before
- cancellation points will work correctly. Therefore,
- while linux threads has the cancel functions implemented,
- deferred cancellation will not really do anything, since
- the co-operation needed from libc is not there.
-
-5) There is a call implemented for FreeBSD (see stack.c):
-
-int _pthread_setstackspacing(size_t spacing, size_t guardsize)
-
-By default, Linux Threads spaces thread stacks 2MB apart, and
-makes each thread stack an "autogrow" stack. If you know that
-your maximum stack for any thread can be less than that, you
-can decrease the spacing by calling this function. It must
-be called before any other pthreads function calls, and it
-will only succeed the first time its called. Note that the
-pthread TLS and the guardsize will be included in the spacing.
-ie. maximum stack size = spacing - TLSpagesize - guardsize.
-
-The spacing must be a power of 2 times the pagesize (and if its
-not, it will be rounded up to the next highest value that is).
-
-6) Note that this is an older version of linuxthreads. More current
-versions are at http://www.kernel.org/pub/linux/libs/glibc.
-
-7) Known problems and issues:
-
-a) It is possible that the instructions given above for including
-liblgcc_r are not sufficent. liblgcc_r is a version of libgcc_r
-linked against this linuxthreads package. It is intended that
-applications link against this, rather than libgcc_r (which is
-linked against libc_r) or libgcc (which is not thread safe).
-
-The normal gcc link options cause libgcc to be included twice
-in the link line (and libgcc_r twice when linking with the
--pthread option). It is therefore possible that a custom link
-line needs to be generated that specifically excludes the
-default libgcc and which includes liblgcc_r twice. There are
-no known problems resulting from the link procedure suggested
-above. However, compiling/linking with the "-v" option will
-illustrate the issue, where lihgcc is included twice in
-addition to liblgcc_r.
-
-b) Since some point around Auguest 30 or later, dynamically linked
-SMP applications have experienced problems with the dynamic linker.
-Statically linked applications appear fine.
-
-Specifically, some applications are not able to resolve dynamic
-links as in this sample output:
-
-root@chiricahua:/usr/ports/devel/linuxthreads/work/linuxthreads-0.71/Examples [119] ./ex4
-Thread 400: allocated key 0
-Thread 400: allocating buffer at 0x804b400
-/usr/libexec/ld-elf.so.1: /usr/local/lib/liblthread.so.0: Undefined symbol "sigfillset"
-
-The problem does not occur on every run, but rather intermittently,
-and the undefined symbol is not always "sigfillset", thought
-this is common.
-
-It is possible that ld-elf.so needs to be made thread safe, and that
-the problem is not unique to SMP but only exposed by the higher
-concurrency of SMP threads. However, the problem has not been
-fully diagnosed.
-
-c) Since August 30 or maybe later, neither this version of FreeBSD
-linuxthreads nor FreeBSD user threads (libc_r) have been able to
-pass the ACE Reactor_Exception_Test using FreeBSD-current. See
-http://www.pinyon.org/ace for information about ACE and compiling
-it under FreeBSD. It is possible that PR/15228 is another illustration
-of the same problem. In both cases the app aborts at line 3314 in
-libgcc2.c in the __sjthrow function, because there is no exception
-handler registered at that point.
-
-Earlier, before August 30, both this version of linuxthreads as well]
-as libc_r passed all the ACE thread tests. The cutoff date for the
-onset of the problem could be later than August 30.
-
-There has not been time to fully diagnose this problem. It occurs
-on both SMP and UP systems.
