| 2003-12-30 | Rework malloc. The new default implementation is based on dlmalloc from Doug | Eric Andersen | |
| Lea. It is about 2x faster than the old malloc-930716, and behave itself much better -- it will properly release memory back to the system, and it uses a combination of brk() for small allocations and mmap() for larger allocations. -Erik | |||
| 2003-12-27 | Fix a long-standing bug with pthreads. A couple of linuxthreads files | Manuel Novoa III | |
| were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests. | |||

| rm.patch: * Define $(RM) as rm -f in Rules.mak and test/Rules.mak (this is the same definition as gmake uses by default). * Change all occurrences of rm and rm -f into $(RM). | |||
| 2003-10-16 | Code formatting cleanup. | Miles Bader | |
| 2003-10-16 | Don't set errno if for zero SIZE returns. | Miles Bader | |
| Code formatting cleanup. | |||
| 2003-09-22 | More fiddling with static free-areas: make sure both their size _and_ | Miles Bader | |
| their alignment are correct. | |||
| 2003-09-19 | Make sure we don't allocate too little space for static free-areas | Miles Bader | |
| because of our fiddling with alignment (because doing so is VERY BAD). | |||
| 2003-09-19 | Add dependencies on header files. | Miles Bader | |
| 2003-09-17 | Make sure static heaps are aligned correctly. | Miles Bader | |
| 2003-09-06 | 'extern inline' doesn't work... Use 'static inline' | Eric Andersen | |
| 2003-09-06 | add missing prototype | Eric Andersen | |
| 2003-09-06 | Fix errno values. Fix MALLOC_GLIBC_COMPAT handling in malloc/malloc.c, | Eric Andersen | |
| which was reversed. Provide more consistancy between implementations. Handle it when people do stupid things like malloc(-1); | |||
| 2003-08-08 | Add in a MALLOC_GLIBC_COMPAT option to let people decide if they | Eric Andersen | |
| want glibc style malloc(0) behavior | |||
| 2003-04-02 | (free_to_heap): Unlock the heap before returning in the | Miles Bader | |
| __UCLIBC_UCLINUX_BROKEN_MUNMAP__ case. Fix from YYang1@Winbond.com.tw. | |||
| 2003-01-23 | Update malloc behavior on malloc(0) to be consistant with | Eric Andersen | |
| malloc-930716 behavior, i.e. return a NULL. | |||
| 2002-11-21 | Debugging tweaks. | Miles Bader | |
| 2002-11-21 | Improve malloc debugging support. | Miles Bader | |
| 2002-10-18 | Don't infinitely recurse when trying to grow __malloc_mmb_heap. | Miles Bader | |
| 2002-10-17 | Fix malloc so it compiles and works when using pthreads | Eric Andersen | |
| -Erik | |||
| 2002-10-15 | Use __heap_[un]lock instead of __malloc_[un]lock. | Miles Bader | |
| 2002-10-15 | Get rid of old malloc lock stuff. | Miles Bader | |
| 2002-10-15 | Fix locking to not deadlock when __UCLIBC_UCLINUX_BROKEN_MUNMAP__ is defined. | Miles Bader | |
| 2002-10-09 | * Add support for uClinux's broken munmap, contingent on | Miles Bader | |
| __UCLIBC_UCLINUX_BROKEN_MUNMAP__ (which is currently not defined anywhere). This makes other cases a tiny bit less efficient too. * Move the malloc lock into the heap structure (locking is still done at the malloc level though, not by the heap functions). * Initialize the malloc heap to contain a tiny initial static free-area so that programs that only do a very little allocation won't ever call mmap. | |||
| 2002-09-13 | (__heap_check_failure): New function. | Miles Bader | |
| (__heap_check): Add more checks. Use `__heap_check_failure'. | |||
| 2002-09-09 | (realloc): Record the correct size in the malloc header in the case | Miles Bader | |
| where we extended the existing allocation, and got back more than we asked for from the heap. | |||
| 2002-09-06 | Initial checkin. | Miles Bader | |
| 2002-09-06 | Update debugging hooks. | Miles Bader | |
| 2002-09-04 | (free): | Miles Bader | |

| 2002-09-04 | (__heap_delete): Renamed from `__heap_unlink_free_area'. | Miles Bader | |

| 2002-08-19 | (MALLOC_SETUP): New macro. | Miles Bader | |

| 2002-08-14 | Use __malloc_unlikely instead of `likely'. | Miles Bader | |
| 2002-08-14 | Add flow-control hints with __malloc_likely and __malloc_unlikely. | Miles Bader | |

| 2002-08-14 | Handle zero NEW_SIZE case. | Miles Bader | |
| 2002-08-13 | Use `return' for null pointers, to avoid a giant block holding the rest | Miles Bader | |
| of the function. | |||
| 2002-08-07 | Per suggestion from Miles Bader, move calloc.c to libc/stdlib. | Eric Andersen | |
| Also, Manuel notices that I forgot to check for when nmemb=0, which would result in a segfault, so fix that case as well. -Erik | |||
| 2002-08-06 | Unify calloc (its the same thing regardless of the underlying | Eric Andersen | |
| malloc implementation). Fix problem reported to bugtraq about problems with integer overflow that can occur during the computation of the memory region size by calloc (and similar functions) which could result in a subsequent buffer overflow. -Erik | |||
