Hi, It would be very helpful, if you can provide us some info on the below issues (Memory leak & Invalid write errors, found from valgrind tool on Sqlite3 library usage).
Executed some Select & Update queries. Don't know if these issue got fixed in the latest sqlite3 library- Sorry for the long mail. Attached below the callflows, for to give more detailed info. Thanks, Kishore Invalid read/write error - 1. ==22067== Invalid read of size 1 ==22067== at 0x40367D3: get_field_type (in /usr/local/lib/dbd/libdbdsqlite3.so) ==22067== by 0x4036C7B: find_result_field_types (in /usr/local/lib/dbd/libdbdsqlite3.so) ==22067== by 0x40372B3: dbd_query (in /usr/local/lib/dbd/libdbdsqlite3.so) ==22067== by 0x40803FA: dbi_conn_query (in /usr/lib/libdbi.so.0.0.5) ==22067== by 0x40414BF: start_thread (in /lib/i686/cmov/libpthread-2.7.so) ==22067== by 0x41686DD: clone (in /lib/i686/cmov/libc-2.7.so) ==22067== Address 0x45786b4 is 0 bytes after a block of size 1,740 alloc'd 2. ==22067== Invalid write of size 1 ==22067== at 0x40367D8: get_field_type (in /usr/local/lib/dbd/libdbdsqlite3.so) ==22067== by 0x4036C7B: find_result_field_types (in /usr/local/lib/dbd/libdbdsqlite3.so) ==22067== by 0x40372B3: dbd_query (in /usr/local/lib/dbd/libdbdsqlite3.so) ==22067== by 0x40803FA: dbi_conn_query (in /usr/lib/libdbi.so.0.0.5) ==22067== by 0x406858E: ExecuteSelectQuery (Ran select query here) ==22067== by 0x41686DD: clone (in /lib/i686/cmov/libc-2.7.so) ==22067== Address 0x4578d3c is not stack'd, malloc'd or (recently) free'd Definite Memory leaks:- 1. ==22067== 64 bytes in 4 blocks are definitely lost in loss record 25 of 67 ==22067== at 0x4023E8C: realloc (vg_replace_malloc.c:429) ==22067== by 0x7E652E4: sqlite3MemRealloc (sqlite3.c:12116) ==22067== by 0x7E2F95F: sqlite3Realloc (sqlite3.c:15503) ==22067== by 0x7E6C041: sqlite3_get_table (sqlite3.c:78723) ==22067== by 0x4036BED: find_result_field_types (in /usr/local/lib/dbd/libdbdsqlite3.so) ==22067== by 0x40372B3: dbd_query (in /usr/local/lib/dbd/libdbdsqlite3.so) ==22067== by 0x40803FA: dbi_conn_query (in /usr/lib/libdbi.so.0.0.5) ==22067== by 0x406858E: ExecuteSelectQuery (Select query call) 2. ==22067== at 0x4023D6E: malloc (vg_replace_malloc.c:207) ==22067== by 0x7E6536A: sqlite3MemMalloc (sqlite3.c:12077) ==22067== by 0x7E2F5FB: mallocWithAlarm (sqlite3.c:15257) ==22067== by 0x7E2F6E7: sqlite3Malloc (sqlite3.c:15288) ==22067== by 0x7E6BE58: sqlite3_exec (sqlite3.c:71018) ==22067== by 0x7E6BF67: sqlite3_get_table (sqlite3.c:78701) ==22067== by 0x4037214: dbd_query (in /usr/local/lib/dbd/libdbdsqlite3.so) ==22067== by 0x40803FA: dbi_conn_query (in /usr/lib/libdbi.so.0.0.5) ==22067== by 0x4069EEE: ExecuteUpdateQuery (dbInterface.c:625) Possible Memory leaks:- 1. ==22067== 183,608 bytes in 427 blocks are possibly lost in loss record 66 of 67 ==22067== at 0x4023E8C: realloc (vg_replace_malloc.c:429) ==22067== by 0x7E652E4: sqlite3MemRealloc (sqlite3.c:12116) ==22067== by 0x7E2F95F: sqlite3Realloc (sqlite3.c:15503) ==22067== by 0x7E42AC2: sqlite3DbRealloc (sqlite3.c:15626) ==22067== by 0x7E6A106: sqlite3Parser (sqlite3.c:63874) ==22067== by 0x7E6A952: sqlite3RunParser (sqlite3.c:89041) ==22067== by 0x7E6AF6C: sqlite3LockAndPrepare (sqlite3.c:74040) ==22067== by 0x7E6BB82: sqlite3_exec (sqlite3.c:70941) ==22067== by 0x7E6C196: sqlite3InitCallback (sqlite3.c:73533) ==22067== by 0x7E6BD55: sqlite3_exec (sqlite3.c:70986) ==22067== by 0x7E6C5BB: sqlite3InitOne (sqlite3.c:73777) ==22067== by 0x7E6C869: sqlite3Init (sqlite3.c:73844) ==22067== ==22067== 2. ==22067== 4,545,024 bytes in 49,232 blocks are possibly lost in loss record 67 of 67 ==22067== at 0x4023D6E: malloc (vg_replace_malloc.c:207) ==22067== by 0x7E6536A: sqlite3MemMalloc (sqlite3.c:12077) ==22067== by 0x7E2F5FB: mallocWithAlarm (sqlite3.c:15257) ==22067== by 0x7E2F6E7: sqlite3Malloc (sqlite3.c:15288) ==22067== by 0x7E31207: pcache1Alloc (sqlite3.c:29244) ==22067== by 0x7E46589: pcache1Fetch (sqlite3.c:29278) ==22067== by 0x7E3DD16: sqlite3PcacheFetch (sqlite3.c:28725) ==22067== by 0x7E50750: sqlite3PagerAcquire (sqlite3.c:34056) ==22067== by 0x7E50D23: sqlite3BtreeGetPage (sqlite3.c:37796) ==22067== by 0x7E50DAF: getAndInitPage (sqlite3.c:37862) ==22067== by 0x7E55589: sqlite3BtreeCursor (sqlite3.c:39587) ==22067== by 0x7E78C5A: sqlite3Step (sqlite3.c:52942) _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
