The readlink() function now uses DOS packet I/O instead of trusting Lock() to do the right thing

Added the header file dependency for the long path handling which makes it build on demand

The long path handling code works much better if you actually check it in

Details matter: the locale_t definition uses an incomplete structure definition, not an anonymous structure.

The definition of 'locale_t' is now based upon a pointer to an "anonymous" structure

Thanks go to sacredbanana for the fix.

Added support for the "d_type" member of the "dirent" structure.
...
If the '_DIRENT_HAVE_D_TYPE' macro is defined after "#include <dirent.h>" has been used successfully, it means that the "dirent" structure features the "d_type" member. The directory entry type values were adapted from 4.4BSD-Lite2, but not all of these are used.

Fix for wrong address alignment rounding

The original V39/V40 amiga.lib puddle creation code did not round up, it rounded off.

Documented why bypassing the read/write buffer is only attempted if there is at least a full buffer worth of data to be read or written.
2023-09-14 09:52:21 +02:00

The inner loop of the read operation already fills the buffer as far as it can go. No need to drop into "continue;".

The SIGABRT handler can no longer invoke abort() recursively.

The size of a slab entry is now calculated inside a single local function, rather than calculated differently in different parts of stdlib_slab.c. This change made it easier to simplify the implementation.

Indentation fix.

Fixed to make use of the aligned slab address when verifying that the slab node is present in the slab. The requested slab size is now properly rounded up to a power of 2 and will always be limited to a valid range.
2023-09-09 18:35:31 +02:00

Fixed the MemoryNode padding, which was short of a 32 bit word.

If the memory management system constructor fails, it now prints some diagnostic debug output.

If the memory debug option is active, realloc() can no longer damage the trailing guard area.

The memory debugging code now places the the damage detection areas which bracket the allocation area so that the originally requested allocation size is used, not the rounded-up size. Debug output in memory node checking no longer counts the non-breaking space character as unprintable.
2023-09-08 16:11:01 +02:00

Simplified how the slab allocator, the memory pool or AllocMem() are being used. Added robust integer overflow detection. Allocation sizes are now padded to a multiple of MEM_BLOCKSIZE. Repaired how the plain AllocMem() allocations are managed. alloca() cleanup is disabled during the stdlib_memory_exit destructor's work. The stdlib_memory_init constructor is more robust and now insists that exec.library V39+ uses memory pools.

Updated to properly use the MemoryNode changes.

Added notes on calloc() being safe to use under certain circumstances if the number of elements or the element size happens to be 0. In effect, malloc() will decide what is going to happen.
2023-09-08 16:04:53 +02:00

If alloca() would end up returning a NULL pointer, it now invokes the default alloca trap function, which calls abort(). You can override this, if you need to.
2023-09-08 16:03:47 +02:00

Modifed the MemoryNode so that its size will always be a multiple of MEM_BLOCKSIZE. The SlabSingleAllocation is now always a multiple of MEM_BLOCKSIZE, too. Tracking whether a MemoryNode is not supposed to be freed is now accomplished through dedicated flag instead of repurposing the allocation size field.
2023-09-08 16:02:37 +02:00
64ba9b5389
Added the __addition_overflows() function prototype, which is used by code which checks for unsigned 32 bit integer sums exceeding the range of an unsigned 32 bit integer.
2023-09-08 16:00:38 +02:00
1286b86f07
Added more robust integer overflow detection. Slab memory is now allocated so that its address starts on a MEM_BLOCKSIZE boundary.

Fixed the bug which broke both fgets() and gets(): copying data from the FILE buffer failed to bump the destination string pointer. Also added an abort check in order to avoid turning the memcpy() operation into an uninterruptable sequence.
2023-09-06 13:27:45 +02:00

Added the common function which both fputs() and puts() share now.

fputs() and puts() now share the same common code. Added abort checks in order to avoid turning the memcpy() operations into an uninterruptable sequence.

Optionally, the slab allocator can be built to deliver 64-bit aligned allocations by default. Also, the slab allocator is no longer enabled at build time.

Small changes to the code documentation
...
The memory pools store puddles near head of the allocation list and the large allocations near the tail of the list.
Some hints added to point to side-effects which might apply to memory allocation operations.
