BZIP2 plugin problem - TAR decompression missing directories

[maxime1008]

Hi,

I noticed on several .tar files that TC's internal decompressor sometimes misses some directories inside the tar file.

Try this one for example:
users.softlab.ece.ntua.gr/~ttsiod/renderer-2.0n.tar.bz2

The bz2 enveloppe is properly handled (by bz2 plugin) but then inside the tar there should be a "src" directory. You can see it if you untar manually with e.g. 7zip or the tar command under Linux, but not in TC.

I tried it on several versions of TC and did not find any similar bug report in the forums.

Any clue?

Thanks,
Maxime

Hello ! Welcome aboard !

• Below is the contents of the BZ2 archive like I can see it by following its structure levels :
1. renderer-2.0n.tar —>
2. renderer-2.0n\ [DIR] —>
3. 3D-Objects\ [DIR]
build-aux\ [DIR]
contrib\ [DIR]
Makefile.in
configure
aclocal.m4
configure.ac
README
NEWS
ChangeLog
INSTALL
AUTHORS
• All sub-dirs. in level “3.” can be opened and show their contents as well.
- In TC 7.04a and in TC 7.50a
• I don't see any [SRC] folder in the “2.” level - but I see the others- that's a bit strange.
- No Unix shell here to check, sorry… I guess that we must wait for the Author's and other users' opinions…

 Kind regards

You can try to open it with the 7zip program under Windows. I just realized two other directories are missing using TC internal unpacker ("ac-macros" and "lib3ds-1.3.0", under the "renderer-2.0n" folder).

Kind regards,

Again…

• I opened and extracted the contents with 7-Zip, but sorry, I see exactly the same than above…
- However, it's a very old 7Z version (4.29ß), because I don't use 7Z a lot,
I'd strongly corrected the French language in that version and miss time for an upgrade…

Thanks for your quick answers

I tried with a more recent version of 7zip (4.65), which shows all the directories.

Again-again…

• I made a quick wild upgrade to 7Z 4.65 and I can confirm now, all folders missing when opening in TC are there !

Oddly enough, WinRar doesn't show those folders either.
Whether opening into it's GUI or unpacking from the context menu.

Using UnxUtils bzip2.exe to decompress the file results in a .tar that is not missing any contents.

[maxime1008]

..Which means that the tar unpacker is innocent, and there is rather a problem during the bzip2 unpacking process used in the TC plugin and in WinRAR.

Again (3)…

• IMHO, Ch. Ghisler might contact Igor Pavlov who is necessarily aware about the reasons for which
the new 7Z 4.65 can see¦unpack all folders, while the old 7Z 4.29ß, TC and WinRar can't do !

Aside : Nice trapped game !

[Balderstrom]

I've sent a bug report to WinRar dev. Since it's very wrong - the bzip2.exe I have is from 2003 and handles the file correctly.

[Balderstrom]

If anyone's interested, got word back from WinRar dev:

This tar.bz2 consists of several smaller bz2 files merged together.
Search for "BZh91" signature in this file and you will see that.
We'll add support for such composite tar.bz2 in next WinRAR version.
Now WinRAR unpacks only the first nested bz2 stream.

Thank you.

This archive was created using "pbzip2" which is "Parallel bzip2", spawning N threads (for multi-core CPUs) and thus executing N-times faster. The README of bunzip2 states it has no problem with the resulting archives.

(source: the author of this archive)

Conclusion: WinRAR and the bzip2 TC Plugin have to update to support multi-core and divide the compression time drastically.

I think we can close the thread ! Thanks for your support.

Another reason to implement native support for 7-Zip.dll

Another reason to implement native support for 7-Zip.dll

It would be very great if TC supported 7z.dll (if user placed it near TOTALCMD.exe like Unrar.dll)...
