Red Hat Bugzilla – Bug 458671
sending packets with wrong format on XIM_QUERY_EXTENSION_REPLY
Last modified: 2009-06-23 00:43:58 EDT
Description of problem:
from XIM specification, the packet syntax for XIM_QUERY_EXTENSION is defined as:
2 CARD16 input-method ID
2 n byte length of extensions supported
by both the IM library and the IM Server.
n LISTofEXT list of extensions supported by
both the IM library and the IM Server.
also EXT is defined as:
1 CARD8 extension major-opcode
1 CARD8 extension minor-opcode
2 n length of extension name
n STRING8 extension name
p unused, p = Pad(n)
This is a dump code what gcin sent back to the client:
D:[transport/summary] 0x6a0003d <- opcode: XIM_QUERY_EXTENSION_REPLY(major: 41, minor 0) length: 36
D:[transport/dump] 0 1 2 3 4 5 6 7 8 9 A B C D E F 0123456789ABCDEF
D:[transport/dump] 29:00:08:00:03:00:1c:00:80:00:30:00:16:00:58:49 ).........0...XI
D:[transport/dump] 4d:5f:45:58:54:5f:53:45:54:5f:45:56:45:4e:54:5f M_EXT_SET_EVENT_
D:[transport/dump] 4d:41:53:4b MASK
Apparently it doesn't follow the above syntax.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.run X application with XMODIFIERS=@im=gcin
2.monitor the packets on XIM protocol.
the client got the wrong packets and can't use the extensions then.
should receives the proper reply.

Candyz, if you could pass this info to upstream that would be helpful.
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
After looking at the diffs among the released archives, this issue seems to be fixed in 1.4.3. so closing this since we've shipped 1.4.5 in F-10 updates.
