| * | two small fixes to free page cache. first, we need two nibbles of random | tedu | 2012-06-20 | 1 | -4/+4 | |
| | | | | | | | in order to span the the entire cache. second, on free use the same offset to put things in the cache instead of always starting at zero. ok otto | |||||
| * | Support larger-than-page-alignment requests in posix_memalign() by | matthew | 2012-06-18 | 2 | -23/+130 | |

| * | Update STANDARDS section for a few <stdlib.h> functions | guenther | 2012-06-02 | 3 | -9/+29 | |

| * | Improve standards conformance: ecvt(), fcvt(), gcvt(), mktemp(), ttyslot(), | guenther | 2012-06-01 | 3 | -8/+11 | |
| | | | | | | | | and valloc() are not in the current version, while posix_memalign() mkstemp(), and mkdtemp() are, and setstate()'s argument has lost a bogus 'const'. ok millert@ jmc@ espie@ kettenis@; ports build testing by naddy@ | |||||
| * | alloca is NOT machine dependent; it has exactly the same | deraadt | 2012-04-12 | 1 | -7/+3 | |
| | | | | | | effective result. its use is NOT discouraged -- it is not common, but when you need it, there is nothing else that will do. | |||||
| * | Fix a bug where random() always returns 0 when srandom() is seeded | millert | 2012-03-21 | 1 | -2/+3 | |
| | | | | | | with 0. Use 1 and not 0 as the first element of the state array, similar to what glibc does. OK nicm@ | |||||
| * | - Test for the retrieved page address not being NULL. This turns free((void*)1) | otto | 2012-02-29 | 1 | -2/+7 | |
| | | | | | | | into an bogus pointer error instead of a segfault. - Document that we use the assumption that a non-MAP_FIXED mmap() with hint 0 never returns NULL. | |||||
| * | Revert previous diff as it resulted in the wrong return code when | guenther | 2012-02-06 | 1 | -5/+3 | |
| | | | | | | | | the last node is deleted. Instead, resolve the Coverity warning by returning (node *)1 when you delete the root node. based an idea from millert@. ok otto@ | |||||

| * | make -column lists pretty again; | jmc | 2011-09-03 | 1 | -3/+3 | |
| | | | | | | | | | | | specifically, rewrite them to permit some markup in the column headers, and use "Ta" instead of literal tabs; mandoc does not currently match groff 100%, but a mandoc fix may be some time off, and we've gone enough releases with poorly formatting column lists. in some cases i have rewritten the lists as -tag, where -column made little sense. | |||||
| * | in column lists, enforce the following ordering: | jmc | 2011-08-30 | 1 | -3/+3 | |
| | | | | | | | | | | .Bl -column header1 header2 ... <Bl flags> mixing things up confuses mandoc, and adding flags in can screw up the list. this hopefully just makes things a bit safer (and more consistent). (one more bit of work left and all column lists should format how we want) | |||||

| * | Introduce leak detection code for MALLOC_STATS | otto | 2011-05-12 | 1 | -25/+165 | |

| * | Move MALLOC_STATS code to bottom of file, so the real stuff is more at the top. | otto | 2011-05-08 | 1 | -137/+141 | |
| | | ||||||
| * | Up until now, malloc scanned the bits of the chunk bitmap from | otto | 2011-05-05 | 1 | -32/+24 | |
| | | | | | | | | | | | | | | | | | | | position zero, skipping a random number of free slots and then picking the next free one. This slowed things down, especially if the number of full slots increases. This changes the scannning to start at a random position in the bitmap and then taking the first available free slot, wrapping if the end of the bitmap is reached. Of course we'll still scan more if the bitmap becomes more full, but the extra iterations skipping free slots and then some full slots are avoided. The random number is derived from a global, which is incremented by a few random bits every time a chunk is needed (with a small optimization if only one free slot is left). Thanks to the testers! | |||||
