[Orca-users] Re: R=?iso-8859-1?Q?=E9?=p. : Re: Further Info

[Guy Dallaire]

The problem lies in the subdirectories, the way I calculated the md5 digest with the "workaround" I mentionned seems to lead to different results for the -daily, -weekly, etc... png files under each host subdirectory. For example, the web server is looking for:

produc/o_produc_disk_runp_c1t6d0,__disk_runp_c0t0d0,__disk_runp_c0t1d0,__disk_runp_md11-S4bRfLG9OD4iSt13vQUHbg-daily.png

But the file that is there is called:

produc/o_produc_disk_runp_c1t6d0,__disk_runp_c0t0d0,__disk_runp_c0t1d0,__disk_runp_md11-NbroWpHa_e9dlyvDxbyilA-daily.png

I presume that when the md5 hash is computed, one is done with the subdir in front of it, and the other without the subdir or something like that. I'm no good at perl, so I won't try to further modify the source.

But I guess the problem was there BEFORE I actually did the modification. I could not test it because it was not wotrking in the first place. Have you tested the code for very long file names ?

Thanks a lot

Do you have your Orca installation viewable from the Internet
so I can take a look at it?
