Zdenek Kabelac	0baf66a992	dm: alloc always 8byte aligned ... Fixing regression caused by 197b5e6dc7. So the 'TODO' part now finally know the answer - there is 'sparc64' architecture which imposes limitation to read 64b words only through 64b aligned address. Since we never could know how is the user going to use the returned pointer and the userusually expects it's aligned on the highest CPU required alignement, preserve it also for char*.

Zdenek Kabelac	fcbef05aae	doc: change fsf address ... Hmm rpmlint suggest fsf is using a different address these days, so lets keep it up-to-date	2016-01-21 12:11:37 +01:00

Zdenek Kabelac	ed463ccf51	Add memory pool locking functions ... Adding debuging functionality to lock and unlock memory pool. 2 ways to debug code: crc - is default checksum/hash of the locked pool. It gets slower when the pool is larger - so the check is only made when VG is finaly released and it has been used more then once.Thus the result is rather informative. mprotect - quite fast all the time - but requires more memory and currently it is using posix_memalign() - this could be later modified to use dm_malloc() and align internally. Tool segfaults when locked memory is modified and core could be examined for faulty code section (backtrace). Only fast memory pools could use mprotect for now - so such debug builds cannot be combined with DEBUG_POOL.	2011-08-11 17:29:04 +00:00
Zdenek Kabelac	197b5e6dc7	Word alignment for strings ... Align strdup char* allocation just on 2 bytes. It looks like wasting space to align strings on 8 bytes. (Could be even 1byte - but for hashing it might eventually get better perfomance - but probably hardly measurable). TODO: check on various architectures it's not making any problems.	2011-03-30 12:57:03 +00:00
Zdenek Kabelac	36b9ec636d	Keep pool name also for pool-fast ... It's cheap to keep this name - and it is useful for 'non pool debug code' compilation.	2011-03-10 14:49:01 +00:00
