Bug 188688 – dev-libs/expat-2.0.1 update breaks apache2

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Frank Breedijk 2007-08-13 08:51:54 UTC]

After upgrading expat from 1.95 to 2.0.1 apache2 failed to start because it could not find libexpat.so.0. This is expected, but executing a 'revdep-rebuild -X --library libexpat.so.0' /usr/sbin/apache2 is still referencing libexpat.so.0.

Reproducible: Always

Steps to Reproduce:
1. Emerge =expat-1.95
2. Emerge apache2
3. emerge -u expat
4. revdep-rebuild -X --library libexpat.so.0
5. /etc/init.d/apache2

Actual Results:  
Apache failed to start, unable to open libexpat.so.0

Expected Results:  
 * Stopping apache2 ...                                                   [ ok ]
 * Starting apache2 ...                                                   [ ok ]

Tested both on amd64 and i586 platform.

Rolled back to expat 1.95

Bugs about revdep-rebuild need to have all /root/.revdep-rebuild* files attached, plus the console output produces by revdep-rebuild. This is not an apache bug.

All .revdep* files from home dir

This is the output of the first devrep run.

[Comment 4 Frank Breedijk 2007-08-13 10:01:41 UTC]

This is not a case of not running revdep-rebuild. This was run and package was correctly identified as needing a recompile.

However, recompilation did not get rid of the dynamic link even tough file was touched.

After manually running 'env-update && emerge --oneshot  =www-servers/apache-2.0.58-r2' to rebuild apache using the new libexpat.so.1 apache will still not start.

A rerun of revdep-rebuild confirms package is not referencing libexpat.so.0. Yet apache refuses to restart.

After creating a synmlink from libexpat.so.1 under the name of libexpat.so.0 apache restarts..

Well, this is not even revdep-rebuild bug; you did run revdep-rebuild with -X (which doesn't stick to specific installed versions), but you need to rebuild not just =dev-libs/apr-util-1.2.8 but also =dev-libs/apr-0.9*, do it now manually or run revdep-rebuild without -X.

[Comment 11 Jakub Moc (RETIRED) 2007-08-13 10:13:12 UTC]

Errr, I meant =dev-libs/apr-util-0.9*, not apr.

[Comment 12 MAL 2007-08-13 11:37:14 UTC]

Then the expat-2.0.1 ebuild needs fixing.

From the ebuild:

ewarn "Please note that the soname of the library changed!"
ewarn "If you are upgrading from a previous version you need"
ewarn "to fix dynamic linking inconsistencies by executing:"
ewarn "revdep-rebuild -X --library libexpat.so.0"

                      ^^
