Radare Summer of Code 2019 Selection Results

Radare2 Summer of Code 2019 Selection Results

As you might remember radare2 organization was a part of Google Summer of Code for many years already. Sadly this year we weren't selected for participation, thus decided to open our own Radare2 Summer of Code season one more time (we did a few time already too). We want to thank NowSecure and KeenLab of Tencent one more time for helping us to make it happen.

The rules and requirements for the RSoC'19 were very similar to GSoC one, with a slightly shifted schedule, so people would give RSoC selection results before the GSoC deadline, to be able apply to GSoC in case of RSoC rejection. Back to the business, this year we accepted two students:

1) spawning is slow, so spawning for each symbol is killing the process
2) you can quickly detect which symbols are mangled by just checking the first 2 chars of the symbol, this reduces the time A LOT
3) swift-demangle can be used to demangle more than one symbol at the time
4) swift is opensource, there's no need to spawn anything
5) the swift demangling apis are accessible (not in last release, but yes in git)
6) there's a swift reimplemenation of the c++ one, just google for it
7) i wrote my own demangler in C (totally incomplete, but enough for most needs)
8) spawning is a process that can be done in paralel. but that's something only Node developers know (ssssh!)
9) python is slow
10) opening any real application with this script will kill your machine
