Requesting support for HBC version 59

[euzada]

Thank you for this great tool. I wonder if a support for HBC version 59 can be added. I will try it myself but i am not sure I will succeeded.

Hi, Euzada. Do you know what react-native version is using the HBC version 59? Or you can just give me the example APK.

Hi, thanks for making this tool, I thought I wouldn't be able to analyze react native apps anymore ! Anyway, I don't know if I should create another issue, but could you also add support for version 62 please ? Used by: com.canaltp.ametis

Thank you

Hi, Euzada. Do you know what react-native version is using the HBC version 59? Or you can just give me the example APK.

It uses Hermes version 0.1.0

I found the version using BytecodeFileFormat.h

at this place in the zip file: hermes-0.1.0.zip\hermes-0.1.0\include\hermes\BCGen\HBC\BytecodeFileFormat.h

https://github.com/facebook/hermes/archive/refs/tags/v0.1.0.zip

Thank you. I hope this is helpful.

I compared the opcode.json file from version 74 in this repository and version 59.

This is what I found different:

• the following are in 74 but not in 59:

  "IteratorBegin": [ "Reg8", "Reg8" ], "IteratorNext": [ "Reg8", "Reg8", "Reg8" ], "IteratorClose": [ "Reg8", "UInt8" ]

• in 74:

"AsysncBreakCheck":[] should be replace in version 59 by: "DebuggerCheckBreak":[]

all other inputs are similar in both versions.

PS: I used BytecodeList.def file to verify the opcode.

Hope this is helpful

@euzada I have to build an Android application. And the react-native version is required not Hermes version 0.1.0. I need it for testing with a real application. However, if, you have the testing APK, please provide it to me. Thank you for your help.

Sorry for my late. my work has been very tiring. I'm working on it at branch add-hbc-v59. Just finish creating unit tests, building the example applications, and add raw material.

Thank you for your help. I tried to build the project with poetry on Windows 10 64 bit, the build works but when I tried to run the test.py I got the following error: No module named 'docopt'. docopt has been installed when I run poetry install as it is in the requirement. Also, I need to copy test.py to the main folder of hbctool to not have the following error : No module named 'hbctool'.

So I tried to compile the project again from scratch.

I run the following command to install the V59 branch: pip install git+https://github.com/bongtrop/hbctool.git@add-hbc-v59

It compiled correctly on windows. I was able to run to hbctool command but if I used hbc version 59 file, I got the following error: AssertionError: The HBC version (59) is not supported.

I don't understand what I am doing wrong?

My work has not to finish yet! Wait a bit.
