Re: [U2] Type 30 files modified when LISTed? (UV 10.0.2)

2013-08-07 Thread Aaron Titus
If I remember correctly, Universe always opens files for update, regardless
if you actually write to the file or not. This will cause the modified time
on the file to be changed.

 Why would a LIST modify the date/time stamp that a file was modified? The
 OVER.30 wasn't changed at this point.

What is odd, is that If I LIST a Type 19/1 file, the time stamp doesn't get 
changed.

hi,

When uv open a T30, it's header is loaded into  uv's shared memory (until all 
user session which adress the file terminate), ready for writing.
File is open for writing, I suppose some header info are updated at open  time.

Type 19/1 files are actually directories at the operating system, not
files.
