After upgrading to sys-libs/gdbm-1.8.3, I was told to run revdep-rebuild --soname libgdbm.so.2. It finished without finding any broken binary, but there *are* some broken binaries, for example /usr/bin/svn. Let's see how revdep-rebuild does its job: ------------------------ if ldd "$FILE" 2>/dev/null | grep -v "$LD_MASK" | $SONAME_GREP -q "$SONAME_SEARCH" ; then if $SEARCH_BROKEN ; then if LD_LIBRARY_PATH="$COMPLETE_LD_LIBRARY_PATH" \ ldd "$FILE" 2>/dev/null | grep -v "$LD_MASK" | $SONAME_GREP -q "$SONAME_SEARCH" ; then echo "$FILE" >>$LLIST.3_rebuild echo_v " broken $FILE (requires $(ldd "$FILE" | sed -n 's/ \(.*\) => not found$/\1/p' | tr '\n' ' ' | sed 's/ $//' ))" fi else echo "$FILE" >>$LLIST.3_rebuild echo_v " found $FILE" fi fi --------------- That isn't right, it doesn't always work. In the case of svn: fiam@americana 63% fiam $ svn svn: error while loading shared libraries: /usr/lib/libgdbm.so.2: file too short fiam@americana 59% fiam $ ldd /usr/bin/svn /usr/bin/svn: error while loading shared libraries: /usr/lib/libgdbm.so.2: file too short revdep-rebuild doesn't mark the file as broken, but it clearly is. Even, more files are broken: fiam@americana 68% fiam $ ./pyrevdep.py libgdbm.so.2 2> /dev/null * Searching system binaries and libraries * Checking dynamic linking * Procesed 6804 of 6805 files (99 %) * /usr/lib/perl5/5.8.4/powerpc-linux/auto/GDBM_File/GDBM_File.so is broken * /usr/lib/perl5/5.8.4/powerpc-linux/auto/NDBM_File/NDBM_File.so is broken * /usr/lib/python2.3/lib-dynload/gdbm.so is broken * /usr/lib/ruby/1.8/powerpc-linux/gdbm.so is broken * /opt/Ximian-OpenOffice/program/python-core-2.2.2/lib/lib-dynload/gdbm.so is broken (svn files doesn't appear because while filing this bug I reemerged svn) pyrevdep.py is using objdump to find broken binaries. Please take a look at http://zeus.linuxlover.org/~skyhusker/pyrevdep.py and tell me your opinions. If you are interested, I can implement all the features of revdep-rebuild in it using python and the portage api.
Created attachment 57460 [details, diff] Removed COMPLETE_LD_LIBRARY_PATH - Added DIR_MASK revdep-rebuild runs ldd with an LD_LIBRARY_PATH expanded with all dir that contains at least an executable or a .so (COMPLETE_LD_LIBRARY_PATH). This helps ldd to find dependencies but it's not real environment when a program run. It's better using the real LD_LIBRARY_PATH to search dependencies and exclude some particular packages like OpenOffice, Acrobat 7 and others. I dropped the expansion of the LD_LIBRARY_PATH and I added a variable for directory exclusion.
same problem with net-mail/courier-imap-3.0.8 revdep-rebuild and patched revdep-rebuild don
same problem with net-mail/courier-imap-3.0.8 revdep-rebuild and patched revdep-rebuild don´t find dependency for courier. skyhuskers pyrevdep.py find´s it. ( thanks skyhusker)
