Re: bash completion slow

Hi Eric,

Thanks for the reply.

The triple stat() issue I am talking about is a thread/patch that I read
from the 2002 timeframe.  I don't think the patch got integrated back tho.

There was another thread that I can't find right now.

Actually Linux readdir doesn't provide any clues about the file either, it
returns the dirent structure.

However, this really opens my eyes as to the problem :

operations, the result of which is just discarded).  With directories in
particular, part of the slowdown is that stat()'s st_nlink field is
populated by counting how many files appear in that sub-directory, even
though readline didn't care about that.

I had the same issue with a tab in /cygdrive/c/ (obviously due to the nasty-ness of the Windows directory). My directory of 300 subdirectories has umpteen files in the subdirectories.

What about turning this subdirectory parsing off by feeding a -1 in
st_nlink in Cygwin?  How could I propose such a change for cygwin?


The best way is to create a patch and then send it to the cygwin-patches
list.  From there, any debate can and will proceed.
