Random decompression errors

[Polar-Pumpkin]

I may encounter "Cannot read file entry: 参数错误。" (from ex.what()) when decompressing on other computer. Trying to get the HRESULT value, the print shows: -2147024809, but I can't find the corresponding HRESULT meaning in my search. 😢

But I use NUnit on my own computer, call my C++ DLL from C#, and decompress it 10,000 times without encountering an error.

The -2147024809 error code corresponds to the E_INVALIDARG HRESULT error (0x80070057 in hex, https://learn.microsoft.com/en-us/windows/win32/seccrypto/common-hresult-values).
This same error happens due to the issue #181, so you may be experiencing it too.
If this is the case, the problem is due to an old bug in MSVC's std::filesystem, which was fixed only in the latest versions of the compiler.
One possible workaround that I proposed is to use the new BIT7Z_DISABLE_USE_STD_FILESYSTEM CMake option provided in the hotfix/v4.0.5 branch, as it makes bit7z avoid using std::filesystem altogether.

Thank you! I'll try it 🥰

After using hotfix/v4.0.5 I haven't had this problem again so far. <3

I'm really curious about how you found the corresponding HEX values. I tried using some online conversion tools, but the HEX values I got don't seem correct. 😢

I just asked ChatGPT, and it helped me convert to a HEX value using the following code.

# Converting the given integer to its corresponding hexadecimal representation

integer_value = -2147417850
hex_value = hex(integer_value & 0xFFFFFFFF)  # Using bitwise AND for two's complement representation
hex_value # 0x80010106

I actually used the Windows calculator app in "Programmer" mode. I just pasted the -2147024809 as a decimal value and then checked the corresponding hex value (ignoring the FFFFFFFF prefix):

This is basically the same operation ChatGPT suggested as Python code.
