| op [fd] prioritize given fd (see also ob)

radare commented 6 years ago

only happens with 3, the other fds are set properly

radare commented 6 years ago

current problem is that only have lot of maps everytime we change the priority of a file with associated bininfo. the bug is in ob code (we also need to decide proper syntax for ob, obb and obo.

Comments are welcome

cc @ret2libc @condret

this is also very related to the RIOSection killification

radare commented 6 years ago

and the thing is. why we want to have multiple maps with the exact same info? i vote for avoiding dupped maps

What's the test binary? Anyway, I see a use case for duplicated maps, but they shouldn't be created for no reason. I think the user should be able to explicitly duplicated a map, but in this case it seems just a bug.

Happens in any binary

Well its calling to reload all the bininfo which implies creating maps
