* Rename _closure to _static_closure, apply naming consistently.Edward Z. Yang2014-10-011-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In preparation for indirecting all references to closures, we rename _closure to _static_closure to ensure any old code will get an undefined symbol error. In order to reference a closure foobar_closure (which is now undefined), you should instead use STATIC_CLOSURE(foobar). For convenience, a number of these old identifiers are macro'd. Across C-- and C (Windows and otherwise), there were differing conventions on whether or not foobar_closure or &foobar_closure was the address of the closure. Now, all foobar_closure references are addresses, and no & is necessary. CHARLIKE/INTLIKE were not changed, simply alpha-renamed.

* Fix cppcheck warningsBoris Egorov2014-09-161-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Cppcheck found a few defects in win32 IOManager and a typo in rts testsuite. This commit fixes them. Cppcheck 1.54 founds three possible null pointer dereferences of ioMan pointer. It is dereferenced and checked for NULL after that. testheapalloced.c contains typo in printf statement, which should print percent sign but treated as parameter placement by compiler. To properly print percent sign one need to use "%%" string. FYI: Cppcheck 1.66 cannot find possible null pointer dereferences in mentioned places, mistakenly thinking that some memory leaking instead. I probably fill a regression bug to Cppcheck. Test Plan: Build project, run 'make fulltest'. It finished with 28 unexpected failures. I don't know if they are related to my fix.

* Raise exceptions when blocked in bad FDs (fixes Trac #4934)Sergei Trofimovich2014-06-081-2/+1
| | | | | | | | | | | | | | | Before the patch any call to 'select()' with 'bad_fd' led to: - unblocking of all threads - hiding exception for 'threadWaitRead bad_fd' The patch fixes both cases in this way: after 'select()' failure we iterate over each blocked descriptor and poll individually to see it's actual status, which is: - READY (move to run queue) - BLOCKED (leave in blocked queue) - INVALID (send an IOErrror exception) Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

| | | | | | | | MSDN says of Sleep: If dwMilliseconds is greater than one tick but less than two, the wait can be anywhere between one and two ticks, and so on. so we need to add (milliseconds-per-tick - 1) to the amount of time we sleep for.

* Deprecate lnat, and use StgWord insteadSimon Marlow2012-09-071-15/+15
| | | | | | | | | | | | lnat was originally "long unsigned int" but we were using it when we wanted a 64-bit type on a 64-bit machine. This broke on Windows x64, where long == int == 32 bits. Using types of unspecified size is bad, but what we really wanted was a type with N bits on an N-bit machine. StgWord is exactly that. lnat was mentioned in some APIs that clients might be using (e.g. StackOverflowHook()), so we leave it defined but with a comment to say that it's deprecated.
* New functions to get kernel thread Id + serialisable task IdDuncan Coutts2012-07-071-1/+7
| | | | | | | | | | | | | | | | | | | | On most platforms the userspace thread type (e.g. pthread_t) and kernel thread id are different. Normally we don't care about kernel thread Ids, but some system tools for tracing/profiling etc report kernel ids. For example Solaris and OSX's DTrace and Linux's perf tool report kernel thread ids. To be able to match these up with RTS's OSThread we need a way to get at the kernel thread, so we add a new function for to do just that (the implementation is system-dependent). Additionally, strictly speaking the OSThreadId type, used as task ids, is not a serialisable representation. On unix OSThreadId is a typedef for pthread_t, but pthread_t is not guaranteed to be a numeric type. Indeed on some systems pthread_t is a pointer and in principle it could be a structure type. So we add another new function to get a serialisable representation of an OSThreadId. This is only for use in log files. We use the function to serialise an id of a task, with the extra feature that it works in non-threaded builds by always returning 1.

| | | | | | | | | | | | | | | | | | | | | Terminology cleanup: the type "Ticks" has been renamed "Time", which is an StgWord64 in units of TIME_RESOLUTION (currently nanoseconds). The terminology "tick" is now used consistently to mean the interval between timer signals. The ticker now always ticks in realtime (actually CLOCK_MONOTONIC if we have it). Before it used CPU time in the non-threaded RTS and realtime in the threaded RTS, but I've discovered that the CPU timer has terrible resolution (at least on Linux) and isn't much use for profiling. So now we always use realtime. This should also fix The default tick interval is now 10ms, except when profiling where we drop it to 1ms. This gives more accurate profiles without affecting runtime too much (<1%). Lots of cleanups - the resolution of Time is now in one place only (Rts.h) rather than having calculations that depend on the resolution scattered all over the RTS. I hope I found them all.
