Description David Binderman 2005-06-30 06:10:18 EDT
Description of problem:

I just tried to compile package httpd-2.0.54-10 from Redhat
Fedora Core development tree with the gcc 4.0.0 compiler and
the compiler flag -Wall.

The compiler said

/usr/src/redhat/BUILD/httpd-2.0.54/modules/dav/fs/repos.c:326: warning: 'perms'
is used uninitialized in this function

The source code is

    apr_fileperms_t perms;

    if (pbuf == NULL)
        pbuf = &work_buf;

    /* Determine permissions to use for destination */
    if (src_finfo && src_finfo->valid & APR_FINFO_PROT
        && src_finfo->protection & APR_UEXECUTE) {
        if (dst_finfo != NULL) {
            /* chmod it if it already exist */
            if (apr_file_perms_set(dst, perms)) {

I agree with the compiler. Suggest initialise local variable "perms"
before first use.

Thanks, yes, the perms = ... line is supposed to be before the
apr_file_perms_set call.
