| 2007-12-03 | realpath: reduce stack usage from 3*PATH_MAX (12k) to 1*PATH_MAX (4k). | Denis Vlasenko | |
| reduction is achieved by direct use of user-supplied PATH_MAX sized buffer for result (without intermediate copy) and changes in copy_buf[] usage - now it is used for both "source" pathname and link name (it works because they have to be less than PATH_MAX combined, otherwise we return NULL). | |||
| 2007-09-19 | Fix author name and copyright notice in __uc_malloc.c | Denis Vlasenko | |
| 2007-09-19 | fix assembler error. libc_hidden_data_def cannot work on COMMONs, | Denis Vlasenko | |
| thus need to initialize stuff with 0 to force it into bss. All hell can again break loose if future gcc will be smart enough to ignore it. | |||

| Hi. I have found a bug in realpath that did not allow me to use it with symlinks. Although I am using 0.9.28.1, the bug is present in 0.9.28 and also in the trunk. I attach a suggested patch. Please let me know if the solution is correct. | |||

| However, retesting on m68k showed up a problem that had appeared in uClibc since the last time I tried. Specifically, revision 15785 did: -#define HEAP_GRANULARITY (sizeof (HEAP_GRANULARITY_TYPE)) +#define HEAP_GRANULARITY (__alignof__ (HEAP_GRANULARITY_TYPE)) -#define MALLOC_ALIGNMENT (sizeof (double)) +#define MALLOC_ALIGNMENT (__alignof__ (double)) The problem is that (a) MALLOC_HEADER_SIZE == MALLOC_ALIGNMENT (b) the header contains a size value of type size_t (c) sizeof (size_t) is 4 on m68k, but... (d) __alignof__ (double) is only 2 (the largest alignment used on m68k) So we only allocate 2 bytes for the 4-byte header, and the least significant 2 bytes of the size are in the user's area rather than the header. The patch below fixes that problem by redefining MALLOC_HEADER_SIZE to: MAX (MALLOC_ALIGNMENT, sizeof (size_t)) (but without the help of the MAX macro ;)). However, we really would like to have word alignment on Coldfire. It makes a big performance difference, and because we have to allocate a 4-byte header anyway, what wastage there is will be confined to the end of the allocated block. Any wastage will also be limited to 2 bytes per allocation compared to the current alignment. I've therefore used the __aligned__ type attribute to create a double type that has at least sizeof (size_t) bytes of alignment. I've introduced a new __attribute_aligned__ macro for this. It might seem silly protecting against old or non-GNU compilers here, but the extra alignment is only an optimisation, and having the macro is more in the spirit of the other attribute code. | |||
| 2007-01-24 | fix from Bryan Wu: return NULL upon error, not the NULL string | Mike Frysinger | |
| 2006-12-17 | rename local "brk" var so it doesnt namespace collide with the brk() function | Mike Frysinger | |
| 2006-12-11 | mostly revert the locking changes for 'malloc', as the implementation | Eric Andersen | |
| does not easily lend itself to becoming complete pthread cancelation safe without first investing in some deep and serious thought... The other malloc implementations are pthread cancelation safe, and this one is mostly used for uClinux, where the lack is at least less likely to be a common problem. | |||
| 2006-12-07 | Major cleanup of internal mutex locking. Be more consistant in how we do | Eric 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. | |||
