Hi,

Isn’t there an issue with the order of the chown and chmod calls in gzip.c?

The source code is now :

 

#ifndef NO_CHOWN

    /* Copy ownership */

# if HAVE_FCHOWN

    ignore_value (fchown (ofd, ifstat->st_uid, ifstat->st_gid));

# elif HAVE_CHOWN

    ignore_value (chown (ofname, ifstat->st_uid, ifstat->st_gid));

# endif

#endif

 

    /* Copy the protection modes */

#if HAVE_FCHMOD

    r = fchmod (ofd, mode);

#else

    r = chmod (ofname, mode);

#endif

    if (r != 0) {

        int e = errno;

        WARN ((stderr, "%s: ", program_name));

        if (!quiet) {

            errno = e;

            perror(ofname);

        }

    }

… but back in version 1.3.5 it was:

    /* Copy the protection modes */

    if (chmod(ofname, ifstat->st_mode & 07777)) {

       int e = errno;

       WARN((stderr, "%s: ", progname));

       if (!quiet) {

           errno = e;

           perror(ofname);

       }

    }

#ifndef NO_CHOWN

    chown(ofname, ifstat->st_uid, ifstat->st_gid);  /* Copy ownership */

#endif

 

(= chmod 1rst, chown 2^nd)

 

We have recently changed servers, thus upgraded from version 1.3.5 to version 1.3.12, and using an “app_user” user we can’t compress .pdf files generated by user oracle any longer.

See the following example:

address@hidden tmp]$ ll 854FAC16809WtT6Ds6dn.pdf

-rw-rw-r-- 1 oracle oinstall 100340  7 août  19:07 854FAC16809WtT6Ds6dn.pdf

address@hidden tmp]$ gzip 854FAC16809WtT6Ds6dn.pdf

gzip: 854FAC16809WtT6Ds6dn.pdf.gz: Operation not permitted

address@hidden tmp]$ echo $?

2

address@hidden tmp]$ ll 854FAC16809WtT6Ds6dn.pdf*

-rw------- 1 oracle oinstall 79847  7 août  19:07 854FAC16809WtT6Ds6dn.pdf.gz

 

Isn’t this a bug?

Best regards.
