Comment (by bonefish):
Replying to [comment:11 anevilyak]:
One point that's unclear to me for this: Since, based on the
aforementioned debug case, we are in fact loading the corresponding
executable image as well, is there any reason the core file needs to be
used for symbols rather than reading them from said image like usual? I
assume that's only necessary so one can analyze the core in the absence of
having a local copy of the executable in question?
The latter is one reason. There are also images (well, one image, the
"commpage") without a corresponding file. That's why symbols are fetched
via the `DebuggerInterface`, which should know how to retrieve the
information. In the local case the implementation does indeed open the
shared object file, if available, falling back to reading the runtime
loader information from the team's memory. We can do pretty much the same
for core files -- with the distinction that we can't use the debug kit
code and that the team memory is more readily available. It probably makes
most sense to port the relevant debug kit code to Debugger and make it
bitness, endianess, and access method agnostic.
Moreover we'll need an indication that an image is possibly or definitely
not local and do file path mapping in this case.
