Recently created topics in Wuala tagged with files

Today I cleared my cache and all of my files were gone, too. That's bad, because my own files get maintained rather regulary, and when they're gone from my account, who guarantees me that my whole file can be reconstructed from the pieces that are in the wild.

so there should be 2 "clear cache" buttons. one for the things i uploaded and the other one for the stuff i downloaded from others. I need the second type of button 1000 times the occasions iI need the first type

hi there,

during my recent upload tests via filesystem integration method (see other thread http://getsatisfaction.com/wuala/topi... ) i somewhen realized that there are hugeloads of files in %temp%\wuala\ which wasnt the case in former builds of wuala.

there are also two directories in there (download and upload)

in the actual %temp%\wuala\ folder there seem to be a very big number of "original" files which i was trying to upload into the wuala store it seems.

the filenames have been changed somewhat to

hexnumber-originalfilename.extension

example:
f3edab22-mypicture.jpg
(hexnumber is maybe some hash/crc/crc32 or something)
the files are unencrypted, so i can actually use them with the appropriate application as they all hold the actual data (pictures, and so on....)

is this some bug? anyway related to my other thread? i suppose this is a huge security risk as even with reboots, wuala clients shutdown/restart these folders dont seem to go away or dont get empied nor cleaned up and the files can be seen by "anybody" who has access to the physical machine.

this is really weird. anyone else having this behaviour? win32/winxp that is. wuala426

lately i have experimented with wuala and fileintegration on win32 (xp) and latest wuala builds (426). i was copying whole cd contents (different files, loads of folder structures) into a semi-private (group/friendshared(only 1 friend as an example/test)) to the wuala network drive (w: for example).

the copying went normally, but only some days after (this happened first some days ago, but i verified it today with other content (CDs)) i realized that the uploaded wuala content of the folder i copied the files into wasnt exactly the same as my original sources. some bytes/megabytes were missing, and i tracked down some of the files/folders that were created but only with filesize=0 (zero), or were missing completely.

i was copying the stuff with the help of total commander, so not the basic builtin explorer.exe functions, nor commandline copy stuff...

i might try some more of this stuff at a later time.

the missing/incomplete files dont seem to follow any certain rules or patterns, there are simply some folders that are completely identical/complete and some files are missing or come with zero size.

totalcommander never complained that it couldnt write to w: or anything else like that.

i was manually looking for the differences, found the missing/incomplete files and was overwriting the files on the wuala store again.

after these second tries and overwriting procedure the wuala store was eventually finally complete and identical to my source material.

i guess that some of the queues in the wuala client, the pending transactions, the chunk-creation and distribution or related functions and parts of the wuala client program are still lacking robustness.

please take a look at this and do your own tests with lots of files/folders and different objectsizes.
thanks.

1. Download History cannot be cleared
2. Cannot see files of a group where i ́m a member of (i know that there are files and that i ́m accepted)
3. The search does not find groups via all tags (the search also looks for upper and lower case letters => case sensitive but tags are not case sensitive)

I'm trying to access a file I recently uploaded and I get the message "This file has not yet been completly uploaded. Please try again later or contact its owner."

When I uploaded the bunch of folders wuala crashed, now it doesn't seem to resume the upload when I start wuala again on the same machine. Is there a way to force resuming of the upload?

Cheers,
reto

File corruption: Small files are padded with null bytes
========================================================================

------------------------------------------------------------------------
BUG DESCRIPTION:
------------------------------------------------------------------------

When downloading small files (less than 4097 bytes) they are padded with null bytes, so that the file size increases up to the nearest 16 byte boundary. This happens both with text and binary files. File sizes are however reported correctly by the Wuala GUI.

------------------------------------------------------------------------
CONFIRMED IN ENVIRONMENTS:
------------------------------------------------------------------------

* Wuala version 74 (linux), Sun Java 6, Ubuntu 7.10, JFS filesystem
* Wuala version 74 (linux), Sun Java 6, Xubuntu 7.10, EXT2 filesystem
* Wuala version 74 (linux), Sun Java 6, Xubuntu 7.10, VFAT filesystem

------------------------------------------------------------------------
STEPS TO REPRODUCE:
------------------------------------------------------------------------

1. Create a directory named "original" and enter it:

$ mkdir original
$ cd original

2. Download the GPLv3 license text (or any other text file):

$ wget http://www.gnu.org/licenses/gpl-3.0.txt

3. Create small extracts of the larger file, ca 4096 bytes in size:

$ for i in `seq 4094 4099`; do (head -c $i gpl-3.0.txt > $i-gpl.txt); done;

4. Go up one level.

$ cd ..

5. Verify the file sizes:

$ ls -l original
-rw-r--r-- 1 hugo hugo 4094 2008-02-24 20:02 4094-gpl.txt
-rw-r--r-- 1 hugo hugo 4095 2008-02-24 20:02 4095-gpl.txt
-rw-r--r-- 1 hugo hugo 4096 2008-02-24 20:02 4096-gpl.txt
-rw-r--r-- 1 hugo hugo 4097 2008-02-24 20:02 4097-gpl.txt
-rw-r--r-- 1 hugo hugo 4098 2008-02-24 20:02 4098-gpl.txt
-rw-r--r-- 1 hugo hugo 4099 2008-02-24 20:02 4099-gpl.txt
-rw-r--r-- 1 hugo hugo 35147 2007-07-02 01:00 gpl-3.0.txt

6. Create a small PNG image (as an example binary file) with for example The GIMP. Check its size:

$ ls -l original/image.png
-rw-r--r-- 1 hugo hugo 129 2008-02-24 20:05 image.png

7. Upload all files into Wuala.

8. Download and "Export to..." all files into a directory named "downloaded".

9. Compare the two directories, and see that original files smaller than 4097 bytes are no longer the same after download:

$ diff -r original downloaded
Binary files original/4094-gpl.txt and downloaded/4094-gpl.txt differ
Binary files original/4095-gpl.txt and downloaded/4095-gpl.txt differ
diff -r original/4096-gpl.txt downloaded/4096-gpl.txt
84c84
_ To "modify" a work means to copy fro
\ No newline at end of file
---
_ To "modify" a work means to copy fro
\ No newline at end of file
Binary files original/image.png and downloaded/image.png differ

10. Compare the file sizes. You should see that the downloaded file sizes are all evenly divisible by 16, for all files whose original file size was less than 4097 bytes:

$ ls -l downloaded
-rw-r--r-- 1 hugo hugo 4096 2008-02-24 20:07 4094-gpl.txt
-rw-r--r-- 1 hugo hugo 4096 2008-02-24 20:07 4095-gpl.txt
-rw-r--r-- 1 hugo hugo 4112 2008-02-24 20:07 4096-gpl.txt
-rw-r--r-- 1 hugo hugo 4097 2008-02-24 20:07 4097-gpl.txt
-rw-r--r-- 1 hugo hugo 4098 2008-02-24 20:07 4098-gpl.txt
-rw-r--r-- 1 hugo hugo 4099 2008-02-24 20:07 4099-gpl.txt
-rw-r--r-- 1 hugo hugo 35147 2008-02-24 20:07 gpl-3.0.txt
-rw-r--r-- 1 hugo hugo 144 2008-02-24 20:07 image.png

11. Inspect the downloaded files and see that they are indeed padded with null bytes (indicated by the 'less' program with '^@'):

(Answer 'y' when asked to display the file even though 'less' considers it binary. Press 'End' to jump to end of file and press 'q' to quit.)

$ less downloaded/4094-gpl.txt
$ less downloaded/4095-gpl.txt
$ less downloaded/4096-gpl.txt
$ cat downloaded/image.png | less

These files should not have any null bytes at the end:

$ less downloaded/4097-gpl.txt
$ less downloaded/4098-gpl.txt
$ less downloaded/4099-gpl.txt
$ less downloaded/gpl-3.0.txt
