[GNUnet-developers] download (too many open files -> crash)

[Christian]

Hi,

Obviously the limit of open file decsriptors allows a maximum of about  
140 simultaneous downloads. When the maximum is reached and one marks  
several(maybe 20, 30 or more) additional files, gtk-gnunet hangs itself  
up by excessively creating popup messages.

I propose (as a fix until the download manager is ready) a hardcoded  
limit of those downloads and prepared a proprietary patch.
Since i also would like the files in the search window to stay after  
downloading them i changed that behaviour also.
I am still not common to the code, so if there is be a better way to go  
around that problem i might try to supply another patch on your  
recommendation :)

The colors in download.c came very handy but wouldnt it be a good idea  
to have a few program wide pre-definitions of colors to use ?
The maximum GNUNET_MAX_DNL is still in the sourcefile i think it should  
be in download.h but i couldnt figure out why the compiler didnt see it  
when i put it there.
