danielk1977	dfb316d432	Changes to delay freeing buffers associated with vdbe memory cells until either sqlite3_finalize() or sqlite3_release_memory() is called. (CVS 4922) ... FossilOrigin-Name: 8c2f69521f13bc24cf005520efbe0589eeadd763	2008-03-26 18:34:43 +00:00
drh	0167f28508	Reorganize the code for the homegrown recursive mutexes. Fix a place ... in the previous check-in where the #ifdef label was incorrect. Ticket #2804. (CVS 4576) FossilOrigin-Name: 542e11f954983ae26fef4ea850c8b2a20f738edd	2007-11-28 14:04:57 +00:00
drh	5f3d652394	Clarify the conditions under which homegrown recursive mutexes work ... (they require a coherent cache) and only enable them if there is an explicit #define so as to avoid accidental use on platforms that do not meet the constraints. Ticket #2805. (CVS 4575) FossilOrigin-Name: 80299eebddba9aac4c1bc36ffa2b440bffbf1751	2007-11-28 13:55:55 +00:00
drh	ed05efbf7b	Add an implementation of recursive mutexes for unix systems that ... lack pthreads recursive mutexes (ex: Solaris 2.6). Modern unix systems continue to use the recursive mutexes provided by pthreads. (CVS 4573) FossilOrigin-Name: f366a776c1b2dda42b4f10fdb8be66029165d084	2007-11-28 00:51:34 +00:00
drh	d0679edc7a	Clean up the locking in the btree logic. (CVS 4316) ... FossilOrigin-Name: 967ab229af462a8ae663090ea36b4cc10e351653	2007-08-28 22:24:34 +00:00
drh	437b901371	Break up the mutex implementation into separate source files, one ... each for unix, w32, and os2. (CVS 4312) FossilOrigin-Name: fc5cd71aef5ac194f51d73350d773d532020967e	2007-08-28 16:34:42 +00:00
