Description Alexey B. Bychko 2008-01-31 15:48:18 UTC 
linuxdcpp-1.0.1 (only this version) fall in cycle on symlinks. After that, hashing thread(?) tries to allocate all possible memory. Seems like where is a bug in directory delimiter handling - '/' (see attached scr)

Reproducible: Always

Steps to Reproduce:
1. Create symbolic link for directory with lot of files - e.g with name "ISO"
2. Share directory symbolic link in linuxdcpp
3. See cycle in status bar and hashing form and available system memory (free -m)


Actual Results:  
memleak + 100% CPU is used. Hashing is not completed

Expected Results:  
linuxdcpp must not infinitely add '/' in directory path, if share is symlink

Comment 2 Alexey B. Bychko 2008-01-31 16:20:20 UTC 
probably, real bug in linuxdcpp - incorrect handling of unknown encoding in directory name. I find 2 directory with cyrillic name and broken encoding (my locale is ru_RU.utf8, these directory names looks like '??????????').
After renaming these dirs, hashing completed successfully.

expected result: if linuxdcpp unable to hash directory, it have to skip it
