As reported by Dmiti Shubin on wiredtiger-users:
In http://source.wiredtiger.com/2.3.1/cursor_ops.html#cursor_error I can read
"For cursor operations that expect a key to be set before the operation begins (including WT_CURSOR::search, WT_CURSOR::insert, WT_CURSOR::update and WT_CURSOR::remove), the application's key and value will not be cleared by an error."
But it seems that cursor::search() drops key value.
Simple test:
$ cat a.c #include <assert.h> #include <stdio.h> #include <string.h> #include <wiredtiger.h> int main(void) { WT_CONNECTION *conn; WT_CURSOR *cursor; WT_SESSION *session; const char *key, *value; int ret; assert(wiredtiger_open(NULL, NULL, "create", &conn) == 0); assert(conn->open_session(conn, NULL, NULL, &session) == 0); assert(session->create(session, "table:access", "key_format=S,value_format=S") == 0); assert(session->open_cursor(session, "table:access", NULL, NULL, &cursor) == 0); cursor->set_key(cursor, "key1"); assert(cursor->search(cursor) == WT_NOTFOUND); //cursor->set_key(cursor, "key1"); ///////////////////// FIX cursor->set_value(cursor, "value1"); ret = cursor->update(cursor); if (ret != 0) { fprintf(stderr, "cursor::update: %s\n", wiredtiger_strerror(ret)); return (ret); } return (ret); } $ gcc -lwiredtiger a.c $ ./a.out [1410189429:594441][24047:00173c388f7f0000], file:access.wt, cursor.update: requires key be set: Invalid argument cursor::update: Invalid argument
If I set the key before update it works as expected.
Am I missing something?
