* Use 'uint32_t' instead of 'long' when a 32-bit integer is intended.David Schultz2004-01-201-31/+32
| | | | | | | | | | | | This results in no functional change, aside from fixing a data corruption bug on LP64 platforms. The code here could still use a significant amount of cleanup. PR: 56502 Submitted by: hrs (earlier version) Notes: svn path=/head/; revision=124738

* Do not adjust to the pagesize at runtime. Besides for the one-timeMarcel Moolenaar2003-11-281-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | initialization overhead, there's a problem in that we never call imalloc() and thus malloc_init() for zero-sized allocations. As a result, malloc(0) returns NULL when it's the first or only malloc in the program. Any non-zero allocation will initialize the malloc code with the side-effect that subsequent zero-sized allocations return a non-NULL pointer. This is because the pointer we return for zero- sized allocations is calculated from malloc_pageshift, which needs to be initialized at runtime on ia64. The result of the inconsistent behaviour described above is that configure scripts failed the test for a GNU compatible malloc. This resulted in a lot of broken ports. Other, even simpler, solutions were possible as well: 1. initialize malloc_pageshift with some non-zero value (say 13 for 8KB pages) and keep the runtime adjustment. 2. Stop using malloc_pageshift to calculate ZEROSIZEPTR. Removal of the runtime adjustment was chosen because then ia64 is the same as any other platform. It is not to say that using a page size obtained at runtime is bad per se. It's that there's currently a high level of gratuity for its existence and the moment it causes problems is the moment you need to get rid of it. Hence, it's not unthinkable that this commit is (partially) reverted some time in the future when we do have a good reason for it and a good way to achieve it.

| | | | | | | | | | | | | | it around an application's fork() call. Our new thread libraries (libthr, libpthread) can now have threads running while another thread calls fork(). In this case, it is possible for malloc to be left in an inconsistent state in the child. Our thread libraries, libpthread in particular, need to use malloc internally after a fork (in the child).

| | | | | | | | | | | | | | send strhash(3) off to sleep with the fishes. Nothing in our tree uses it. It has no documentation. It is nonstandard and in spite of the filename strhash.c and strhash.h, it lives in application namespace by providing compulsory global symbols hash_create()/hash_destroy()/hash_search()/ hash_traverse()/hash_purge()/hash_stats() regardless of whether you #include <strhash.h> or not. If it turns out that there is a huge application for this after all, I can repocopy it somewhere safer and we can revive it elsewhere. But please, not in libc! Notes: svn path=/head/; revision=121639

Among the changes: - Declare strtof() and strtold() in stdlib.h. - Add glue to libc to support these routines for all kinds of ``long double''. - Update printf() to reflect the fact that dtoa works slightly differently now. As soon as I see that nothing has blown up, I will kill src/lib/libc/stdlib/strtod.c. Soon printf() will be able to use the new routines to output long doubles without loss of precision, but numerous bugs in the existing code must be addressed first.

| | | | | | | | | | | | | | | | | | seed->first value correlation. It breaks rand_r()... Other possible methods like shuffling inside aray will breaks rand_r() too, because it assumes only one word state, i.e. nothing extra can be added after seed assignment in srand(). BTW, for old formulae seed->first value correlation is not so monotonically increased as with other Linear Congruential Generators of this type only becase arithmetic overflow happens. But overflow affects distribution and lower bits very badly, as many articles says, such type of overflow not improves PRNG. So, monotonically increased seed->first value correlation problem remains... Notes: svn path=/head/; revision=111026
