Red Hat Bugzilla – Bug 81367
can't print from Raw Hide mozilla
Last modified: 2007-04-18 12:49:35 EDT
When I try to print from the mozilla with everything current from Raw Hide, it hangs after putting up the "Preparing..." dialog. When I strace mozilla-bin before doing the print, the strace says that it vforks and then tries to write to the child process, and the write blocks. It appears as if the child process isn't actually doing anything after the vfork (unless strace itself is confused): 1203 pipe([24, 25]) = 0 1203 vfork() = 1224 1203 close(24) = 0 1203 write(23, "neto 0 -684 rlineto -504 0 rline"..., 1688) = 1688 1203 _llseek(23, 0, [0], SEEK_SET) = 0 1203 read(23, "%!PS-Adobe-3.0\n%%BoundingBox: 18"..., 4096) = 4096 1203 fstat64(25, {st_mode=S_IFIFO|0600, st_size=0, ...}) = 0 1203 old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40e9a000 1203 read(23, "ont setfont } bind def\n/F7\n /"..., 4096) = 4096 1203 write(25, "%!PS-Adobe-3.0\n%%BoundingBox: 18"..., 4096) = 4096 1203 read(23, "2 /b\n16#0063 /c\n16#0064 "..., 4096) = 4096 1203 write(25, "ont setfont } bind def\n/F7\n /"..., 4096) = ? ERESTARTSYS (To be restarted) The end of the last line above was printed after I killed the child process, after waiting for quite a while for it to do something. This happens repeatedly, i.e., it wasn't a fluke.
Might be lpr having issues?
Well, does saving it to a file and doing 'lpr <mozilla.ps' work?
Yes, printing to a file and then feeding the file into lpr does work.
Wait, I'm going to take that back. It works erratically. Sometimes it prints, sometimes it doesn't. But it never hangs -- when it doesn't print, it simply exits with no error but nothing comes out of the printer.
'Working erratically' seems to be a different bug. At the time of the mozilla hang, what does 'ps axf' show about its child processes? By the way, strace doesn't follow vfork by default.
I know strace doesn't do vfork by default; I specified "-f -F" when I ran it to produce the output shown above. Here's what the mozilla process tree looks like after it hangs: > ps auxw | grep mozilla-bin jik 12895 0.0 0.0 0 0 pts/0 Z 09:45 0:00 [mozilla-bin <defunct>] jik 12889 4.5 5.2 49596 26900 pts/0 S 09:45 0:04 /usr/lib/mozilla-1.2.1/mozilla-bin jik 12909 0.0 5.2 49592 26896 pts/0 S 09:47 0:00 /usr/lib/mozilla-1.2.1/mozilla-bin > pstree -p 12889 mozilla-bin(12889)-+-mozilla-bin(12895) `-mozilla-bin(12909)
Are you just running 'some' rawhide packages, or is this an updated Phoebe installation?
When I reported this bug, I was completely up-to-date with Raw Hide. Since then I've had to back down some Raw Hide packages because of incompatibilities with vmware.
It occurs to me I never asked if this is cups or LPRng (oops!).
It occurs to me that I never specified :-). CUPS.
Is this still happening?
I haven't seen this recently.
Marking WORKSFORME based on reporter comments.
