MinidumpYAML: Add support for the memory info list stream

Authored by labath on Oct 8 2019, 7:40 AM.



The implementation is fairly straight-forward and uses the same patterns
as the existing streams. The yaml form does not attempt to preserve the
data in the "gaps" that can be created by setting a larger-than-required
header or entry size in the stream header, because the existing consumer
(lldb) does not make use of the information in the gap in any way, and
attempting to preserve that would make the implementation more

Nit: Title says "thread" rather than "memory info"

Nit: Title says "thread" rather than "memory info"

Woops, sorry about that. Should be fixed now.

FYI, I'm going to be away for 2 and a half weeks from the end of work today, so won't have time to look at these if I don't get to them later today. I have no issues with other people reviewing them. You might want to add @grimar and @MaskRay to the reviews as they've been doing a lot of work in obj2yaml/yaml2obj recently.

Maybe be more explicit here, i.e.

std::vector<minidump::MemoryInfo> &&Infos

Probably just

minidump::MemoryInfoListHeader Header = {


Or perhaps it could have a constructor.

The thought of a constructor has crossed my mind too. I've now added it.

Move default constructor above.

Or let the constructor take iterator_range<MinidumpFile::MemoryInfoIterator> as the argument, and change the call site below.

Done, I've also moved the constructor of SystemInfoStream for consistency.
