Subject: [9fans] deadlock in page(1)
Date: Wed, 8 Jan 2003 11:40:28 +0000 [thread overview]
Message-ID: <10448d781152600dab2fec6cee720288@hamnavoe.demon.co.uk> (raw)
In-Reply-To: <0c17a7e1153d16dbd94d0f2a5fe7b1a0@plan9.bell-labs.com>
When page calls gs to display a postscript file which uses \r as a line
terminator (not \n or \r\n), deadlock ensues. Here's a correction (which
may also reduce the need for the '-P' option):
/sys/src/cmd/page/ps.c:429 a ps.c:430,434
> /*
> * If last line terminator is \r, gs will read ahead to check for \n
> * so send one to avoid deadlock.
> */
> write(ps->gsfd, "\n", 1);
