2008-06-07- revert incorrect parts of r22257 and 22259Bernhard Reutner-Fischer
since posix_openpt lives in getpt.c it has to stay there unconditionally.
2008-06-07- remove __USE_BSD guard from __bsd_getpt().Bernhard Reutner-Fischer
Fixes compilation error for defined UCLIBC_HAS_PTY && !defined UNIX98PTY_ONLY which need both __libc_ptyname1 and __libc_ptyname2 for ptsname_r().
2008-06-07- UCLIBC_HAS_GETPT pulls in getpt.Bernhard Reutner-Fischer
- ptsname_r depends on UCLIBC_HAS_PTY just like ptsname()
2008-06-04This fixes a problem with the move of libc_hidden_proto to string.h.Bernd Schmidt
The obsolete functions bcopy, index, etc. are not supposed to be used within uClibc itself. Hence, there is no libc_hidden_def for them, but the previous patch did not just move libc_hidden_protos, it also added new ones for the legacy functions. As a result, programs which use these functions can no longer link with uClibc. This fixes it by removing the unnecessary libc_hidden_protos. I've also removed all inclusions of <strings.h> from uClibc source files: since we define _GNU_SOURCE, it is sufficient to include <string.h>. We then do not need to duplicate the libc_hidden_proto block in <strings.h>.
2008-06-03- adds several config-options to allow for turning off certain featuresBernhard Reutner-Fischer

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.

2008-01-05michael_d writes in 1879:Mike Frysinger
When no TIOCGPTN definition is present in the kernel headers, the library's ptsname() function will not work. The libc/stdlib/ptsname_r.c file is the problem. This file includes a complicated nest of #if directives. One of these #if's has the opposite sense from what is required.
2007-12-03realpath: 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).
2007-09-19Fix author name and copyright notice in __uc_malloc.cDenis Vlasenko
2007-09-19fix 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.

2007-01-29Richard Sandiford writes:Mike Frysinger
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.

2006-12-11mostly revert the locking changes for 'malloc', as the implementationEric 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.
2006-12-07Major 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.
