Description
running nginx with -c and process substitution or a named pipe fails where the same config loaded from a normal file succeeds.
success (from a file)
[carl@carlminion1 bin]$ nginx -c /home/carl/bin/gar.conf
[carl@carlminion1 bin]$ nginx -c /home/carl/bin/gar.conf -s stop
fail (from process sub)
[carl@carlminion1 bin]$ nginx -c <(cat /home/carl/bin/gar.conf)
nginx: [emerg] no "events" section in configuration
fail (from named pipe)
[carl@carlminion1 bin]$ nginx -c /home/carl/bin/test (shell 1)
[carl@carlminion1 bin]$ cat gar.conf > test (shell 2)
nginx: [emerg] no "events" section in configuration (shell 1)
Note:
See TracTickets
for help on using tickets.
Yes, nginx uses generic file reading mechanism to read config file, and it fails with fifos/pipes due to file size not known and pread() function used. There are no plans to fix this.
