[mod_cluster-issues] [JBoss JIRA] (MODCLUSTER-613) mod_cluster_slotmem doesn't use the same ftok() than apr

[Jean-Frederic Clere (JIRA)]

    [ https://issues.jboss.org/browse/MODCLUSTER-613?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13452056#comment-13452056 ] 

Jean-Frederic Clere commented on MODCLUSTER-613:
------------------------------------------------

looking in sharedmem_util.c:
+++
apr_status_t unixd_set_shm_perms(const char *fname)
{
#ifdef AP_NEED_SET_MUTEX_PERMS
#if APR_USE_SHMEM_SHMGET || APR_USE_SHMEM_SHMGET_ANON
    struct shmid_ds shmbuf;
    key_t shmkey;
    int shmid;

    shmkey = ftok(fname, 1);
+++
and looking in apr-1.5.x there is:
+++
#if APR_USE_SHMEM_SHMGET
static key_t our_ftok(const char *filename)
{
    /* to help avoid collisions while still using
     * an easily recreated proj_id */
    apr_ssize_t slen = strlen(filename);
    return ftok(filename,
                (int)apr_hashfunc_default(filename, &slen));
}
#endif
+++

That looks fishy....
