2001-08-10 Not Zed <NotZed@Ximian.com> * wordindexmem.c (sync_cache_entry): NOOP if writing to a failed file. (word_index_pre): NOOP if failed file. (ibex_create_word_index_mem): Setup blocks value. ** Added internal exception handling to libibex, in the case of errors with on-disk data, exceptions are returned. * block.c (ibex_block_cache_open): Detect fatal errors below us and clean up appropriately. (ibex_block_cache_fail): New function to handle the failure, and keep track of it. (ibex_block_cache_sync): Dont do anything if we've failed on this file. * disktail.c (tail_compress): Add blocks param so we can assert for exceptions. * hash.c, block.c disktail.c: g_assert->ibex_block_cache_assert where dealing with external data. * hash.c (hash_info): Add index param so we can assert for exceptions. * ibex_block.c (ibex_index_buffer): Setjmp before calling into internal routines. (ibex_save): " (ibex_unindex): " (ibex_find): " (ibex_find_name): " (ibex_contains_name): " (ibex_reset): Function to reset the index file if we have an error, call when we have an error. * block.h (ibex_block_cache_assert): Create assertion/exception macros, and include a setjmp buffer for returning it. 2001-08-09 Not Zed <NotZed@Ximian.com> * Makefile.am (libibex_la_SOURCES): Remove wordindex.c, wordindexmem is what's used. svn path=/trunk/; revision=11864
