rar 5 help for sabnzbd noob

[rsmik]

I have come across some archives packed with rar 5, I only find this out after sabnzbd (version 0.7.16) finishes processing the download and I get a large file with no extension. I would hate to have to turn off automatic unrar and manually unpack everything I download using winrar 5. Is there a stupid noob way to configure sabnzbd to use unrar 5 instead of whatever is built in and how do I go about doing this? Thanks

[sander]

Which platform is running SABnzbd running on? Linux, OSX, Windows, NAS, ... ?

And, out of curiosity: can you PM a link to such a rar5 newspost?

SABnzbd has an option "Enable Unrar Enable built-in unrar functionality.". That's on by default. I'm not sure what happens when you uncheck ... maybe SAB search for a unrar executable in the OS path?

I uses winrar5 and selected RAR5 as archive type, and created bigrandomfile-rar5-winrar-FTW.rar

The unpack results:

unrar3 doesn't work:

Code: Select all

$ unrar3 x bigrandomfile-rar5-winrar-FTW.rar

UNRAR 3.30 beta 3 freeware      Copyright (c) 1993-2003 Eugene Roshal

bigrandomfile-rar5-winrar-FTW.rar is not RAR archive
No files to extract

unrar 4 doesn't work:

Code: Select all

$ unrar4 x bigrandomfile-rar5-winrar-FTW.rar

UNRAR 4.20 freeware      Copyright (c) 1993-2012 Alexander Roshal

Unsupported archive format. Please update RAR to a newer version.
bigrandomfile-rar5-winrar-FTW.rar is not RAR archive
No files to extract

but unrar5 works:

Code: Select all

$ unrar5 x bigrandomfile-rar5-winrar-FTW.rar

Extracting from bigrandomfile-rar5-winrar-FTW.rar

Extracting  random-100MB.bin                                          OK 
All OK

So indeed it's possible unrar 5 is needed.

Have you tried unchecking the SABnzbd option I mentioned? You shoud first install unrar 5 in your OS path.

Thanks for all your help, I really appreciate it. I replaced unrar.exe that came installed with sabnzbd with version 5 and am now able to unpack the archives correctly.

[sander]

Cool. One advice/warning: SABnzb up to 0.7.16 cannot handle the output of unrar5 in case of password encrypted rars. So watch out for that.

0.7.17 and pw protected releases.. i can confirm the included 5.0.1 works fine on detecting encrypted releases..

0.7.17 windows binary install comes with:

Code: Select all

C:\Program Files (x86)\SABnzbd\win\unrar\x64>UnRAR.exe -V
UNRAR 5.01 freeware      Copyright (c) 1993-2013 Alexander Roshal

checking release manually:

Code: Select all

C:\Program Files (x86)\SABnzbd\win\unrar\x64>UnRAR.exe l "C:\Users\test\Documents\downloads\incomplete\_removed_release_name_\82F5cDB7vvCDeLW_qxitosXF36.part01.rar"

UNRAR 5.01 freeware      Copyright (c) 1993-2013 Alexander Roshal

Enter password (will not be echoed) for C:\Users\test\Documents\downloads\incomplete\_removed_release_name_\82F5cDB7vvCDeLW_qxitosXF36.part01.rar:
Checksum error in the encrypted file C:\Users\test\Documents\downloads\incomplete\_removed_release_name_\82F5cDB7vvCDeLW_qxitosXF36.part01.rar. Corrupt file or wrong password.
Archive: C:\Users\test\Documents\downloads\incomplete\_removed_release_name_\82F5cDB7vvCDeLW_qxitosXF36.part01.rar
Details: RAR 4, volume, lock, encrypted headers

so as we can see, its rar4 format not 5. and sure enough it is pw protected.

sab 0.7.17 binary install detects this as it should:

Code: Select all

2014-04-01 14:10:32,390::WARNING::[assembler:117] WARNING: Paused job "_removed_release_name_" because of encrypted RAR file

switched from 0.7.17 win folder to 0.7.16 win folder. (changing back to unrar 4.20), started up sab and added the nzb back.. it detected it as encrypted once again:

Code: Select all

2014-04-01 14:40:26,323::INFO::[assembler:88] Decoding C:\Users\test\Documents\downloads\incomplete\_removed_release_name_\82F5cDB7vvCDeLW_qxitosXF36.part01.rar yenc

2014-04-01 14:40:27,209::WARNING::[assembler:117] WARNING: Paused job "_removed_release_name_" because of encrypted RAR file

so overall good to go.. reverted win folder changes back to 0.7.17 binary install.

talking to a user in irc about this, hence my test above.
turns out i have pre check disabled. turned it on, restarted sab (0.7.17). added nzb. notice it now doesnt catch the release is encrypted anymore while it's downloading... only catches it when it finishes the whole thing..

[_flake]

With completion checking enabled .17 is not detecting passworded releases until the complete release is leeched.

[shypike]

Yes, that's because SABnzbd cannot decode RAR5 files on its own yet.

[zoggy]

Yes, that's because SABnzbd cannot decode RAR5 files on its own yet.

if you see above, the release is in rar4 format. i thought it was a rar5 thing at first.. why i checked both.. turned out its a pre-check bug. hence my github issues report

*update* i see you must be talking to the original poster which yes is rar5.

btw shy rar5.10b1 adds some things that may be nice for sab..

Version 5.10 beta 1

1. Added extraction support for ZIP and ZIPX archives using BZIP2, LZMA and PPMd compression.
2. Added extraction support for 7z split archives (.7z.001, .7z.002, ...).
3. Added support for AES-NI CPU instructions allowing to improve RAR encryption and decryption performance.
