New in 2.3:
* LWP builds and passes simple tests on amd64/em64t.
* Avoid crash when running lwp_basher.
* Work around broken makecontext on amd64
* Fix warning in rw.c
* Fix some autoconf/automake warnings during bootstrap.
* On bootstrap, get rid of the autom4te.cache. (Phil Nelson)
* struct ucontext changed to struct lwp_ucontext. (Phil Nelson)
New in 2.2:
* Removed cross-compilation spec files.
* Avoid stack overflow in the tdb test program on sparc64.
* FC5 build fixes.
* Don't package the link created by ldconfig.
New in 2.1:
* Sometimes we can only switch to a context created by makecontext once.
Refreshing the context information with getcontext to make the jump into the
thread reaper repeatable.
* Move declarations before code, gcc-2.95 likes that better. (Greg Troxel)
* The uc_stack in a ucontext may be clobbered by the context switching
functions. Use a separate copy in the lwp process info for stack overflow
checks and deallocation purposes.
* Use setjmp/longjmp to jump out of the signal context when using sigaltstack
to spawn a new thread instead of simply returning. This avoids corruption of
the newly created context. (Phil Nelson)
New in 2.0:
* Use ucontext.h provided functions for thread creation and switching.
In case those are not available use sigaltstack for thread creation
and sigsetjmp/siglongjump for thread switching, and if sigaltstack
doesn't exist fall back on the old process.S assembly code.
* Simplified pthread support a bit, now it builds and runs on cygwin.
* RPM .spec file fix to allow non-root users to build (Matthew Rich).
* Included AIX process.S assembly, since I don't know the right ifdefs,
it isn't actually part of process.S yet.
* This library is binary compatible with previous releases. But some of
the prototypes of callback functions got cleaned up a bit so that
building against this version of LWP will give some trivially fixable
compile warnings or errors.
New in 1.13:
* Stack switching code for AMD64 processors (Brett Lymn).
New in 1.12:
* Updated build dependencies.
New in 1.11:
* Updated to automake 1.7, autoconf 2.52, libtool 1.5.2
* Some pthreaded lwp issues.
* Corrected substitution when register_t is not defined.
New in 1.10:
* autoconf changes, 2.50 is now required to build.
* Some uninitialized memory references found by valgrind.
New in 1.9:
* autoconf 2.5x.
* OpenBSD patches from Jeff Bachtel.
New in 1.8:
* gcc-3.0 compilation (trailing garbage after #endif).
New in 1.7:
* Fixed <sys/time.h> vs. <time.h> mixup.
* Applied MacOS X (Darwin) patches from Timothy Wood.
New in 1.6:
* Merged debian packaging files.
* Using same version number for all libraries.
* Applied RedHat build patch from Bruce Guenter.
New in 1.5:
* Removed signal based preemption code.
* Removed all access to global variables from assembly code.
* Moved process.ss to process.S, to use correct compilation flags.
* Ported to NetBSD-mips.
* Fixed shared library problems for mips and sparc (and arm?).
* Using fd_set for IOMGR_Select.
* Fixed broken handling of the select timeout.
New in 1.4:
* Ported to Linux-arm (Jason Flinn).
* Ported to FreeBSD-alpha.
* Fixed unaligned access problems on 64-bit machines..
* Increased the IOMGR stacksize to 32KB to avoid stackoverflows.
* Avoid lock.h nameclashes with Coda on the list_head definition
(_pt version only).
New in 1.3:
* Disabled building shared libraries by default, enabling it only for
platforms that seem to work correctly (currently only i386).
* Updates for Solaris-i386 (from Phil Nelson).
New in 1.2:
* Phil Nelson fixed the compilation problems on Solaris.
New in 1.1:
* Fixed a bad stackbase on NetBSD/FreeBSD platforms.
* Fixed a locking bug in lock_pt.c.
* Using pthread_attr_setdetachstate in lwp_pt.c instead of modifying the attr
struct directly.
* Improved cross-compiling with cygwin32 and djgpp.
* Added a script that might produce a useable ports/packages descriptions.
* Wrote a bit in the INSTALL document.
New in 1.0:
* Extracted LWP out of the main Coda source tree.
* Using an automake/autoconf/libtool build environment.
* Creating shared libraries.
* Added pthreaded version of the lwp library.
* Fixed some bugs in the included test programs.
