+[TC 8.50 betas and RC1] Unable to open non-full RAR file

[MaxX]

How to reproduce:
1. Open any browser you wish (my case - Opera 12.x)
2. Start a download of any RAR file (v 4.x).
3.(While downloading) try to open target file in TC.
4a. TC 8.01 - works fine, I can see what's inside RAR file and can't unpack - it's normal.
4b. TC 8.50 (betas and rc1) - get an error: can't go inside (See screenshot: http://iceimg.com/Juayinv6/clip463.png).

Tested with TC 8.01 final, TC 8.50 last betas and RC1 on Win 7 SP1 x64 and with internal unrar*.dll files.
Also I've tested TC with the lastest unrar*.dll from rarlab.com - get the same result.

But why should I look into an archive which is not yet fully downloaded ?

Why not? For the simple reason that you want to extract just one file of interest to you. Instead of asking why better focus on how to solve the problem?

This bug has basically the same cause as reported here: http://www.ghisler.ch/board/viewtopic.php?t=39301

If youd really care for solving this problem then why not go to the root (rarlabs) instead of talking here about it?

This is a misfeature of unrar.dll: It cannot open RAR archives which are open in any other program. Older TC versions didn't use unrar.dll to read names. TC 8.5 has to use it to support RAR5 format.

Can you add some function to open archive in legacy mode (just the same as it was before in 8.0x)?
Any command I could use via user-defined hotkey.
I need such a feature due to the specific backup system.

[atomix]

I fully support this request, please make it happen.

[ghisler(Author)]

Unfortunately not, because the old functions had other limitations, like
- not opening files with encrypted file names
- only opening current part of multi-part RAR

I know it and don't need these extras for additional legacy-mode with it's own hotkey.

I know it and don't need these extras for additional legacy-mode with it's own hotkey.

I am also happy with the behaviour of TC 8.01 (and earlier) and I see this change in 8.50 as a regression, so a legacy-mode would be most welcome.

As for people suggesting to contact rarlab - I did that already but I don't put my hopes too high since this is not an issue in their WinRAR product.
Perhaps Christian can get their attention as a software developer using unrar.dll

[ghisler(Author)]

I have sent an e-mail to the RAR author, but I don't have high hopes for a change. I have added code to open the archive with the old method when it is locked, but this doesn't allow to unpack files from it because this needs the unrar.dll again. But the same problem was true for TC 8.

ZIPs also can't be opened while they are downloaded, but ZIPs are handled by TC 100% internally...

[ghisler(Author)]

Actually it can when you enable the option to open partial zips in menu configuration - options - zip packer.

Btw, great news: The RAR author has replied to my request! It's now not only possible to browse RAR archives which are open, but also extract files from them! It's included in RC2 now, please test it!

[MaxX]

Quick test's done, works fine.

WOWWWWWW i didn't expect this to happen anymore.

that problem really kept me off from upgrading to 8.5 so far.


this *seems* now to fix

and

http://www.ghisler.ch/board/viewtopic.php?t=38867

not thoroughly tested yet though.


btw, the people at RARLAB were also helpful when i contacted them because of another RAR problem.

so, well done.
