** Description changed: FFE Section for disco --------------------- [Rationale] This change to mod_auth_mellon adds a very useful capability for enabling diagnostics output from the module: https://github.com/Uninett/mod_auth_mellon/commit/e8579f6387d9841ce619d836110050fb18117753 It is available as of v0.14.0 (present in Cosmic): git --no-pager tag --contains=e8579f6387d9841ce619d836110050fb18117753 v0.14.0 v0.14.1 This is generally useful for field engineering and operations teams and other users as SAML exchanges are difficult to debug. [Build Verification] https://paste.ubuntu.com/p/2kt3BsxJKn/ [Installation] https://paste.ubuntu.com/p/VcfcgyPHqH/ "MellonDiagnosticsEnable Off" is the default setting and it results in am_diag_open_log returning 1 which does NOT result in an error returned from am_diag_log_init. Also installed a package and verified that setting this to off explicitly or implicitly (default) does not result in errors on startup or page access. https://git.launchpad.net/ubuntu/+source/libapache2-mod-auth- mellon/tree/auth_mellon_diagnostics.c?h=ubuntu/disco&id=49c8ccfedca2db17d76348573e6daa862e104f6d#n311 int am_diag_log_init(apr_pool_t *pc, apr_pool_t *p, apr_pool_t *pt, server_rec *s) { for ( ; s ; s = s->next) { if (!am_diag_open_log(s, p)) { return HTTP_INTERNAL_SERVER_ERROR; } } // ... static int am_diag_open_log(server_rec *s, apr_pool_t *p) { // ... if (!(diag_cfg->flags & AM_DIAG_FLAG_ENABLED)) { ap_log_error(APLOG_MARK, APLOG_DEBUG, 0, s, "mellon diagnostics disabled for %s", server_desc); return 1; // ... [Upgrades] No impact - SRU section - ----------- + SRU section for cosmic and bionic + --------------------------------- [Impact] See FFE Rationale above. [Test Case] [Regression Potential] As mentioned above in the FFE section, "MellonDiagnosticsEnable Off" can be set in the apache configuration to disable diagnostics. This is also the default setting, so regression potential is certainly limited by this. + + [Discussion] + For the cosmic SRU this will be a fairly straight forward and trivial update to the package to run configure with "--enable-diagnostics". Cosmic is already at version 0.14.0 which has the diagnostics support. + + For the bionic SRU, things are more complicated as bionic is at version + 0.13.1 which does not include diagnostics support. I've analyzed the + delta between 0.13.1 and 0.14.0 and I'm seeing mostly bug fixes and 2 + new features (1 for diagnostics support, and 1 for MellonSignatureMethod + support).
