* Delete the XXX comments that refer to spinlock recursion. The malloc/free/John Birrell1998-09-301-15/+1
| | | | | | | | | | | | realloc functions check for recursion within the malloc code itself. In a thread-safe library, the single spinlock ensures that no two threads go inside the protected code at the same time. The thread implementation is responsible for ensuring that the spinlock does in fact protect malloc. There was a window of opportunity in which this was not the case. I'll fix that with a commit RSN.

* Back out part of previous commit (even though it's technically correct).Alexander Langer1998-09-201-1/+17
| | | | | | | | | | | | | | Our spinlock implementation allows a particular thread to obtain a lock multiple times, but release the lock with a single unlock call. Since we're detecting recursion, we know the lock is already owned by the current thread in a previous call and must not be released in the current call. This is really far too dependent on this particular spinlock implementation, so I've added commented out calls to THREAD_UNLOCK in the appropriate places. We can activate this code when spinlock is taught to count each lock operation. Notes: svn path=/head/; revision=39501

* Replace memory leaking instances of realloc with non-leaking reallocf.Warner Losh1998-09-162-2/+2
| | | | | | | | | | | | | | In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes. Shouldn't impact anything, but...

A second commit will be done to commit the conversion of those places in the code that can safely use this to avoid memory leaks when confronted with low memory situations.

* This is a hack to workaround source that is coded to use long variablesJohn Birrell1998-05-082-2/+2528
| | | | | | | | | | | | | but also assumes that they are 32-bits. This is one place where I don't think it is appropriate to change 'long' to 'int'. I don't see why the code couldn't be fixed so that using natural long variables does the right thing. It's spaggetti code so it'll take some effort. Obviously NetBSD thought so too because they change 'long' to 'int32_t' etc and left it at that. As a temporary measure FreeBSD/Alpha can use the NetBSD code and put this on the list of things to fix. Notes: svn path=/head/; revision=35837

* | Fix mutex initialization.John Birrell1997-06-041-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Malloc cannot use pthread_mutex_init() to initialize a mutex because the mutex initialization process does a malloc! libc_r internals skip the malloc and assign an initializer to a static structure and point the opaque type (pthread_mutex_t in this case) to that structure. This is done on the assumption that the mutex will never be destroyed. This style of initialization is only valid inside libc_r because the structure that is assigned is opaque to the user. This fix allows a simple program to get to main() again. 8-) Notes: svn path=/head/; revision=26444
