8.97. libtevent

Updated libtevent packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The libtevent packages provide Tevent, an event system based on the talloc memory management library. Tevent supports many event types, including timers, signals, and the classic file descriptor events. Tevent also provides helpers to deal with asynchronous code represented by the tevent_req (Tevent Request) functions.


The libtevent packages have been upgraded to upstream version 0.9.18, which provides a number of bug fixes and enhancements over the previous version. (BZ#951034)

Bug Fixes

Prior to this update, a condition in the poll backend copied a 64-bit variable into an unsigned integer variable, which was smaller than 64-bit on 32-bit architectures. Using the unsigned integer variable in a condition rendered the condition to be always false. The variable format has been changed to the uint64_t format guaranteeing its width to be 64 bits on all architectures. As a result, the condition now yields expected results.
Previously, the tevent_loop_wait() function internally registered its own signal handler even though it had been never removed. Consequently, tevent_loop_wait() could not end even there were no registered custom handlers. This update applies a patch to fix this bug and tevent_loop_wait() now works as expected.
Users of libtevent are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
