Description
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?
