Title: lefty readline from pipe hangs on Solaris
Submitter: Marko Mäkelä
Date: December 11, 2002
Subsys: dotty/lneato/lefty
Version: 1.8.10
System: sparc-sun-solaris2.8
Severity: major
Problem:
The visualization interface of my program "maria" (http://www.tcs.hut.fi/Software/maria/) fails on Solaris. When I try to use any functions that would communicate to the dotty-based "maria-vis" script via pipes, the dotty window opens, but the mouse pointer inside the window remains as a wristwatch and nothing happens.
Comments:
I think I reported this bug about one year ago, but my fix has not been applied.
Fix:
Remove the fseek call from the file graphviz/lefty/os/unix/io.c, function IO_readline. The calls are probably unnecessary in IO_writeline as well, but they do not cause any harm.
