Package: libapt-pkg4.12 Version: 0.9.5.1 Tags: patch Noticed this while using PendingError in aptitude and getting some strange behaviour. PendingError returned false yet DumpErrors immediately after would output errors. Some quick debugging showed that _error->StackCount had been increased somewhere.
In pkgcachegen.cc the function MakeStatusCache has a call to PushToStack, followed by conditional calls to either Revert. or Merge.. However, these are not enough to ensure that the stack count is always left as it started. If there is no error and Debug is false then StackCount will remain incremented, hiding older errors from subsequent calls to PendingError. A quick check using 'grep -e Stack -R apt-pkg/ apt-inst/ cmdline/ methods/' reveals no similar problems. Patch. Applying this patch could affect the exit status of some apt-get commands in some situations. I can only see that it would be more accurate in the presence of errors. Regards
