[Bug general/4852] New: Never use Proc.getExe() except for display (possible) executable path

[mark at klomp dot org]

Proc.getExe() returns a path to the (possibly incorrect) of the executable being
examined. Since it isn't guaranteed to be correct it should never be used for
anything except for informational messages. Since it is often correct it is used
in places in frysk-core to get at the executable, this is not correct though
(for example when examining a core file it is not the executable you are
interested in, but the data/text/code collected by the CoreFile reader). In
particular these files should be examined and changed that create Elf objects
directly from the Proc.getExe() result:

frysk-core/frysk/debuginfo/DebugInfo.java
frysk-core/frysk/proc/TestTaskObserverCode.java
frysk-core/frysk/proc/dead/TestLinuxCore.java

frysk-core/frysk/dom/DOMImage.java uses getExe() to get at the include paths for
the source.

frysk-core/frysk/proc/IsaFactory.java getIsa() reads /proc/pid/exe directly.

frysk-gui also uses getExe() repeatably, but probably correctly, these should be
checked though:

frysk-gui/frysk/gui/sessions/WatchList.java
frysk-gui/frysk/gui/monitor/GuiProc.java
frysk-gui/frysk/gui/monitor/PickProcListView.java
frysk-gui/frysk/gui/monitor/PickProcsListView.java
frysk-gui/frysk/gui/monitor/filters/ProcPathFilter.java
frysk-gui/frysk/gui/monitor/PickProcDialog.java
frysk-gui/frysk/gui/srcwin/SourceWindow.java
