Systems that generate large numbers of errlog messages or have a slow
message listener could overwrite older messages in the message buffer
after the buffer wraps. This also corrects and annotates the test
code to describe what's being checked.
Build lexer and parser from libCom/Makefile.
Since libCom now includes asLib.c and asLib_lex.c we must build
antelope and flex without linking them to Com. This works because
they only need epicsTempFile anyway. However make doesn't like a
subdirectory with the same name as a target object, so the antelope
source directory is now called yacc. The two main.c files were also
renamed to avoid other build problems.
Merge asHost into Com and remove mentions in CONFIG_BASE
Lots of noise since SRCS must be renamed to Com_SRCS
The new Makefile fragments in the subdirectories are incomplete and will
not work individually. Build rules are placed in a separate RULES file.
This approach keeps the instructions for building each file local and
easier to find than in a large Makefile in the parent directory.
o Fixed race condition where win32 thread parm was not pushed onto the
list before the thread was started, and so if the thread exits very
quickly it can try to remove a non-existent thread parameter from
the list.
o This impacts only win32.
* Renamed the enum epicsEventWaitStatus to epicsEventStatus
* Defined epicsEventWaitStatus as a macro for epicsEventStatus
* Renamed epicsEventWaitOk to epicsEventOk
* Renamed epicsEventWaitError to epicsEventError
* Defined epicsEventWaitOK and epicsEventWaitError as macros
* Added epicsEventTrigger(id) which triggers an event and returns OK or an
error status if the underlying OS primitives report an error
* Added epicsEventMustTrigger(id) which halts on error
* Defined epicsEventSignal(id) as a macro for epicsEventMustTrigger(id)
* Added a new C++ method epicsEvent::trigger() which throws an
epicsEvent::invalidSemaphore in the event of an error
* epicsEvent::signal() makes an inline call to epicsEvent::trigger()
* epicsEventWait() and epicsEventWaitWithTimeout() now return an error
status if the underlying OS primitives report an error
* All the epicsEventMust...() routines are now implemented in the common
libCom/osi/epicsEvent.cpp source file, and call cantProceed() instead of
mis-using assert()
* Implemented epicsEventShow() on Posix
Each SRC_DIR gets its own Makefile fragment, and where it needs
private build rules a RULES files.
If this pattern gets used elsewhere we could automate the include
lines (search $(SRC_DIRS) for Makefiles and RULES files?).
Don't use epicsMutexMustLock() in msgbufGetFree().
When we're shutting down, the pvtData.msgQueueLock gets destroyed.
This makes msgbufGetFree() return NULL if the lock is dead.
The epicsMutexMustLock() routine asserts(), which recurses...
Cygwin 1.7 changed the socket shutdown method from BothShutdown
to Close. This fix looks at the cygwin version to work out what
value to return from esscimqi().
o gnu compiler for windows doesnt support well dll exporting individual functions from a class
in debug builds so I switched to exporting the entire interface class in several places
o fixed several places in ca lib where include of epicsTimer.h wasnt properly ifdef'd so
that it is imported by ca header files
--- these issues were already fixed on cvs main trunk ---
Made epicsThreadOnceTest more deterministic, replacing an
epicsThreadSleep() with epicsEventMustWait(), and added a diagnostic
message before running the thread recurse test.
Eric added a series of checks to epicsEventTest.cpp which ensure that
epicsEventSignal() only wakes one waiting thread.
This allows calc and calcout record expressions to be up to
79 characters long, and shortens the postfix buffer needed by
introducing integer literals. Also removes the length limit
for access security CALC expressions.
