I do this all the time and have no problems with it. I usually do this to filter logs and organize them into an archivable structure with cronolog. Sounds like your problem is that httpd is blocking because there is no reader on the pipe. Make sure whatever is reading from the pipe is doing so *before* httpd writes to it and does not close the handle or exit. Also make sure httpd exits before the reader exits. If the reader disapears, then httpd will hang until it comes back (or forever if not). Stupid example showing blocking from lack of reader: # Make named pipe $ mknod foo p # Start a reader in background $ cat foo & [1] 2000 # Write and reader will echo and then exit $ echo bar > foo bar [1]+ Done cat foo # Attempt to write again and it blocks w/o reader $ echo bar > foo # Ctrl+Z to stop, then background the hung writer $ bg [1] 2010 $ cat foo bar [1]+ Done echo bar >foo -B On 5/13/06, Harry Rüter <harry_rueter@xxxxxx> wrote:
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hallo list, i was trying to write logs into a named pipe, but had i no success (httpd-2.0.54). httpd is waiting/blocking forever and must be killed ... Any idea ? Is a patch existing ? How can i tell the developers allowing to write logs into named pipes would be a wonderful feature ?
