changes in sbcl-1.0.26 relative to 1.0.25:
+ * incompatible change: the interruption (be it a function passed to
+ INTERRUPT-THREAD or a timer function) runs in an environment where
+ interrupts can be enabled. The interruption can use
+ WITH-INTERRUPTS or WITHOUT-INTERRUPTS as it sees fit. Use
+ WITHOUT-INTERRUPTS to avoid nesting of interruptions and
+ potentially running out of stack. Keep in mind that in the absance
+ of WITHOUT-INTERRUPTS some potentially blocking operation such as
+ acquiring a lock can enable interrupts.
* incompatible change: GC-OFF and GC-ON are removed, they were
always unsafe. Use WITHOUT-GCING instead.
* new feature: runtime option --disable-ldb
memory, stack, alien stack, binding stack, encountering a memory
fault, etc. In the absence of --lose-on-corruption a warning is
printed to stderr.
+ * improvement: generally more stable and reliable interrupt handling
+ * improvement: there is a per thread interruption queue,
+ interruptions are executed in order of arrival
+ * improvement: a repeating timer reschedules itself when the it has
+ finished, but expiration times are spaced equally. If an
+ expiration time is in the past it will trigger after a short grace
+ period that may give a chance to other things to run.
* optimization: slightly faster gc on multithreaded builds
* optimization: faster WITHOUT-GCING
+ * bug fix: when JOIN-THREAD signals an error, do it when not holding
+ important locks so that the debugger/handler doesn't produce
+ recursive errors or deadlock.
* bug fix: real-time signals are not used anymore, so no more
hanging when the system wide real-time signal queue gets full.
+ * bug fix: INTERRUPT-THREAD on a dying thread could produce memory
+ fault.
* bug fix: finalizers, gc hooks never run in a WITHOUT-INTERRUPTS
+ * bug fix: fix random memory faults related to interrupts on alpha
+ * bug fix: fix deadlocks related to starting threads
changes in sbcl-1.0.25 relative to 1.0.24:
* incompatible change: SB-INTROSPECT:FUNCTION-ARGLIST is deprecated, to be
