KISSDB_get always failing when failed once

[noeldum]

Working on a multiple access database. If a call to KISSDB_get fails as the key does not exists yet then that call will always fails even though the key has been written by another process.

Not sure if this is a bug or an expected behaviour. My work around for now is to close and reopen the db.

I wrote these two codes to illustrate this. A and B. On an existing db run A which should say fail as the key 100 does not exists. While A runs run B to write the key 100. A will still say fail. Close A and relaunch. It will now find the key.

A

#include <stdio.h>
#include "kissdb.h"
#include <inttypes.h>
#include <signal.h>
#include <unistd.h>

static volatile int keepRunning = 1;
void intHandler(int dummy) {
	keepRunning = 0;
}

int main(int argc, char *argv[]){
	KISSDB db;
	uint64_t paquets[2];
	uint64_t key = 100;
	KISSDB_open(&db,"test.db",KISSDB_OPEN_MODE_RDWR,1024,8,sizeof(paquets));
	
	
	while (1){
	
		if (KISSDB_get(&db, &key, paquets)) printf("fails\n");
		else printf("ok\n");
		sleep(2);	
	
	}
}

B

#include <stdio.h>
#include "kissdb.h"
#include <inttypes.h>
#include <signal.h>
#include <unistd.h>

static volatile int keepRunning = 1;
void intHandler(int dummy) {
	keepRunning = 0;
}

int main(int argc, char *argv[]){
	KISSDB db;
	uint64_t paquets[2];
	uint64_t key = 100;
	KISSDB_open(&db,"test.db",KISSDB_OPEN_MODE_RWCREAT,1024,8,sizeof(paquets));
	KISSDB_put(&db, &key, paquets);
	KISSDB_close(&db);
