2008-05-19Moving libc_hidden_proto's into #ifdef UCLIBC_INTERNAL blockDenis Vlasenko
in string.h and strings.h. This caught unguarded string ops in libc/inet/ethers.c __ether_line_w() function. I will wait for fallout reports for a week or so, then continue converting more libc_hidden_proto's.

2006-12-07Major cleanup of internal mutex locking. Be more consistant in how we doEric Andersen
things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking.

Dont forgive that length of munmap is "0" in current nommu. This purpose cannot free memory area really. It is a patch to work out a solution.
2004-07-15Use MAP_PRIVATE whenever __ARCH_HAS_MMU__ is set.Eric Andersen
Only use MAP_SHARED when mmu-less.

Fix uninitialized pthread mutex used to lock the list of aligned memory blocks.
2003-12-30Rework malloc. The new default implementation is based on dlmalloc from DougEric 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
2003-12-30Update and restore malloc-simple. Slow as molasses, but triviallyEric Andersen
simple and releases memory immediately when asked to do so. -Erik
2002-07-18Miles Bader implemented a new mmap based malloc which is muchEric Andersen
smarter than the old "malloc-simple", and actually works, unlike the old "malloc". So kill the old "malloc-simple" and the old "malloc" and replace them with Miles' new malloc implementation. Update Config files to match. Thanks Miles!

2001-04-25Be more strict with the malloc implementation. Return NULLEric Andersen
when folks do a malloc(0) using malloc-simple. -Erik
2001-03-19Fix up breakage resulting from flipping the sense of some defines. Change fromEric Andersen
defining things to "0" in the disabled case to outright undefining them, lest code that does an "#ifdef FOO" get inadvertantly triggered. Remove now unneeded lines from Rules.mak which makes the command line smaller and avoids redundancy (since this stuff is now pulled in via features.h). -Erik
2001-02-13Use MAP_FAILED.Eric Andersen
2001-01-12Patch from James Graves <jgraves@deltamobile.com> to better handle m68k.Eric Andersen
Also fixes 2 very important malloc bugs! Anyone using malloc (esp mmu-less) should update and recompile. -Erik
2000-10-11Finish reorganizing things. At least I think I've finished.Eric Andersen
