Debug level 16 gave me 0 bytes. mlink@mcs.anl.gov 2004-10-21 18:33:11 That should read 15. (It is just a bitmask). This got me thinking about user specified log levels. I can interperet the user log level as what they give || every level below, i.e. your 16 would have become a 31 internally, but then users lose the ability to selectively pick different levels. Obviously giving them that ability means I have to provide tags for the levels and the user will specify a list of tags. i.e. -l error,info,dump ... (numbers could still be used of course) Is any of this useful? Would a user ever want a high level output but not the lower levels? rynge@isi.edu 2004-10-21 18:51:07 I think a straight scale of 0 (only errors) to 15 (everything) is easy to use and makes sense. The ORing of levels would only be useful if logical names were used, not numbers (ie, error,info,dump instead of 7,8,12). Note that with logical names we would get very close to syslog(3). allcock@mcs.anl.gov 2004-10-21 20:01:04 Subject: RE: Gridftp logging levels (is 7>10?) Yes, I definitely think so. If you had zeroed in on the area where the problem was, you would only want that info, not wade through tons of other stuff. mlink@mcs.anl.gov 2004-10-25 10:13:49 I made log levels selectable with text tags (error,warn,info,dump,all), or a single digit. If the digit is given it will make sure to select all levels below and including that digit. This should handle the common case of a user picking an arbitrary high number expecting to get a lot of output. People that want selective levels will use the tags. Mike
