jeparse exit abnormally #18

Closed ddwolf closed 2 years ago

ddwolf commented 2 years ago

I am using the commit c54da79f2ab5215901ee3b3c7e804802e2ef4c79 and it failed like this:

[shadow] parsing structures from memory...
[shadow] 2021-11-03 18:13:59
[shadow] error: cannot evaluate arenas[0]
Python Exception <type 'exceptions.SystemExit'> <type 'exceptions.SystemExit'>: 
Error occurred in Python command: <type 'exceptions.SystemExit'>

if I use the latest version then it complained: Error occurred in Python command: No symbol "arena_bin_t" in current context

the jemalloc I am using is 5.2.1-0-gea6b3e973b477b8061e0076bb257dbd7f3faa756

This is unfortunately expected behavior. The tool was originally developed with jemalloc version 4.x in mind. With the release of version 5, the layout of the used data structures changed significantly. "arena_bin_t" is a name of a data structure in version 4. It is replaced in version 5 by the structure "bin_t" with a similar (not identical) function. There was some effort to port the tool to version 5 and Android 10 but it is far from complete. The relevant code is on the android10 branch.
