Hi,
here comes Xenomai v2.5.2, codenamed "Souls Of Distortion" available
from Xenomai download area:
http://download.gna.org/xenomai/stable/xenomai-2.5.2.tar.bz2
It contains important fixes for several bugs found in previous versions:
- silent memory corruption induced by the "u_mode" feature;
- bad return values of posix and native condition variables (also add
some unit tests for condition variables, to allow tracking regressions);
- fix error handling in xnintr_detach().
Some improvements in several area:
- a new --with-testdir option allowing to install xenomai testsuite
programs in a special directory, to avoid collision with other programs;
- a bunch of improvements from the analogy branch;
- made a libxenomai library factoring the code common between all skins,
with a change in the xeno-config script, making it simpler to use (you
now pass the script the skin for which you are compiling, and the output
ldflags contain the name of all libraries);
- get the select syscall more in-line with the behaviour dictated by the
POSIX spec.
And I am probably forgetting some other important changes, short log
follows:
