Status: RESOLVED WONTFIX

(Core Graveyard :: Plug-ins, defect, P2)

Description

[lsof]

Selecting "print" from a flash animation causes Mozilla to hang.
I do not have a printer installed.
Printing from Mozilla itself does not cause Mozilla to crash.
Flash 5.

Killing mozilla leaves flash's right-click context menu still visible.
Killing this window is not possible using xkill without the -frame option.

nada, I can't reproduce this. pls give me a testcase url, Thx!. I do not have a 
printer setup on my linux box too but the console spits out a 'could not connect 
"error and gives back the control to me..i do no experience a hang.

I'm seeing this with Linux trunk build 20020824.  stacktrace is:
#0  0x4197e2b2 in gImgLog () from /usr/lib/netscape/plugins/libflashplayer.so

it stays in the function forever.

I strace'd Mozilla and when I did the "print" it started doing this...

write(28, "LT\n4555 3907 LT\n4556 3907 LT\n455"..., 2048) = 2048
write(28, "LT\n4552 3925 LT\n4552 3926 LT\n455"..., 2047) = 2047
write(28, "4563 3927 LT\n4563 3927 LT\n4563 3"..., 1060) = 1060
write(28, "showpage\n%%PageTrailer\n", 23) = 23
write(28, "0 792 translate\n0.118 -0.115 sca"..., 53) = 53
mmap2(NULL, 2998272, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x42e70000
write(28, "newpath initclip\n/CT { curveto }"..., 2048) = 2048
write(28, "b4d4a5b4d49db4d49db4d4a5b4d4a5b4"..., 2048) = 2048
write(28, "95a5b495a5b495a5b495a5b495a5b495"..., 2048) = 2048
write(28, "c49dacc49dacc49dacc49dacc49dacc4"..., 2048) = 2048
... (lots of this)
write(28, "4e2e554e2e5d55265d552655462e5546"..., 2048) = 2048
write(28, "7575367575367575366d5d2e6d5d2e75"..., 2048) = 2048
write(28, "26755d26755d267d752e7d752e7d6d2e"..., 2048) = 2048
munmap(0x42e70000, 2998272)             = 0
write(28, "752e756d36756d36756d366d5d266d5d"..., 2047) = 2047
write(28, "LT\n4543 3922 LT\n4543 3922 LT\n454"..., 2046) = 2046
write(28, "4593 3948 LT\n4595 3948 LT\n4595 3"..., 2046) = 2046
write(28, "3978 LT\n4565 3978 LT\n4566 3980 L"..., 2048) = 2048
(lots of this, repeat)

looks like it's trying to make a .ps file(s)

Comment 8

[rubydoo123]

This is not failing on windows, Shrir can you test this using the listed example
on a linux build?

Comment 9

[rubydoo123]

needs to be verified by QA

Comment 10

[shrirang khanzode]

cannot repro on 1209 trunk build on linux. 

Comment 11

[lsof]

Browser still hangs when using build 2002121208.

STRACE:
write(31, "bfa777bfa777bfa777bfa777bfa777bf"..., 2048) = 2048
write(31, "77bfa777bfa777bfa777bfa777bfa777"..., 2047) = 2047
write(31, "a777bfa777bfa7\n77bfa777bfa777bfa"..., 2048) = 2048
write(31, "bfa777bfa777bfa777bfa777bfa777\nb"..., 2048) = 2048

killall gives:
Status Information:
 sending job 'sb@localhost+293' to missingprinter@localhost
 connecting to 'localhost', attempt 1
 cannot open connection to localhost - No such file or directory
Make sure the remote host supports the LPD protocol
and accepts connections from this host and from non-privileged (>1023) ports

I do not have a printer.

Does this happen in Flash 6?

Comment 13

[lsof]

Flash 6 is fine - it opens a Print dialogue box.

Comment 14

[Peter Lubczynski]

-->WONTFIX

The hang happens while inside the Flash plugin and there isn't much the browser
can do about it. It also appears that this problem has been fixed in the newly
released Flash 6 so just upgrade.
