How to download source, modify source, recompile and build .deb package?

  • 772

I have to customize my Apache2 suExec module to ensure some special environment variables getting passed through suExec.

How to download the source code form Debian package apache2-suexec, modify suexec.c -> safe_env_lst, recompile and build a .deb package again to rollout on the production systems?

I tried apt-get source apache2-suexec but didn't found the suexec.c within the occurred apache2-* folder.

The altered source code should be like this:

static const char *const safe_env_lst[] =
{
    /* variable name starts with */
    "HTTP_",
    "SSL_",

    /* NEW: Perl debugging variables */
    "PERL5OPT=",
    "PERL5LIB=",
    "PERLDB_OPTS=",
    "DBGP_IDEKEY=",

    /* NEW: FCGI variables */
    "FCGI=",
    "FCGI_CONNECTION=",
    "FCGI_RUNTIME=",
    "FCGI_STARTTIME=",
