+[8.50ß1-3] TC asks for RAR file pw using external packer

[Bluestar]

Hi,

In case you try to extract a simple RAR file using ALT+F9 (alias cm_UnpackFiles) then a Password dialog pops up, even if I have previously unchecked the "Use internal un-RAR if possible" option in Configuration/Packer.

Then after typing in the correct password it also starts the associated "WinRAR.exe" file, which also asks for the correct password.


Reproduce:
01. cm_PackerConfig
02. Set the RAR packer path to your WinRAR.exe file
03. Uncheck the "Use internal un-RAR if possible" option and save the settings
04. Create a RAR file with filenames having encrypted in it (cannot reproduce in case of a simple password protection where filenames can be seen!)

For example (pass: tc):

Code: Select all

UmFyIRoHAM6Zc4AADQAAAAAAAADpJw6fn9ss9KNLd1Zv48mSdOH0qxfQHZqQP/2wIM9L+OL03z4F
mNS3/3fcyIc1Q2pivbJbq4r73BdIPHICKQGwFAlJwHr07NmT1+bedew11a8+0fWt5BPo6ScOn5/b

05. Try to extract it using Alt + F9 -> TC asks for password, even if it shouldn't in this case -> you type in the pw -> it doesn't pass it to WinRAR, so it asks for password again -> successful extract


(btw I'd gladly use TC's built-in unpacker, but it doesn't have a pw manager for example, which has been added to winrar recently & i use this function a lot, since I work with encrypted archives all the time...)

The problem exists in TC8.50ß1-ß3 (tested under W7SP1x86 & TCx86).

I think TC reads archive structure itself anyway (there's no way to get contents from external unpackers), and only performs unpacking using external unpacker. So, it needs the password to read archive contents.

[Bluestar]

But why should it read the structure of the archive itself, in case I disabled the internal unpacker & just wants to unpack the whole archive, without knowing the exact files it contains?

Shouldn't it just have to pass the file to the associated executable, as it did so in 7.56 / 7.57a & the final 8.01? That approach seemed much better to me...

[MVV]

I think ignore list etc may be used only in case when TC reads contents itself. And it doesn't do any differences between whole and partial unpacking.

I will check it - there should be no need to ask for the password on Alt+F9.

I can confirm it has been fixed in TC 8.50ß4 - thank you Mr. Ghisler!
