Subject: Run helpers in the same process group as the main process but instead
X-Git-Tag: SQUID_3_0_PRE4~740
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3b6888743c44cb1703273e1a66ed84d6cd0797e8;p=thirdparty%2Fsquid.git

Run helpers in the same process group as the main process but instead
disable SIGINT for the helpers when not running in daemon mode.

This accomplishes several things

  a) The helpers may access /dev/tty for screen output (debug purposes)

  b) A "kill -9" can be sent to the whole process group at once.
