Bug ID: 104972
Summary: eventstruct "out" function is undefined
Product: XCB
Version: unspecified
Hardware: All
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Protocol
Assignee: ***@lists.freedesktop.org
Reporter: ***@gmail.com
QA Contact: ***@lists.freedesktop.org

Please see the following stack trace, which indicates that the eventstruct
functionality added in
https://cgit.freedesktop.org/xcb/proto/commit/?id=4aa40fbd5e05833b72327ea37421b09dff246732
is broken, and causing the xcb-proto package to fail altogether, even on basic
import statements:

```
File "/home/edj/Repos/polybar/lib/xpp/generators/cpp_client.py", line 3163,
in <module>
from xcbgen.state import Module
File "/usr/lib/python3.6/site-packages/xcbgen/state.py", line 7, in <module>
from xcbgen import matcher
File "/usr/lib/python3.6/site-packages/xcbgen/matcher.py", line 12, in
<module>
from xcbgen.xtypes import *
File "/usr/lib/python3.6/site-packages/xcbgen/xtypes.py", line 1201, in
<module>
class EventStruct(Union):
File "/usr/lib/python3.6/site-packages/xcbgen/xtypes.py", line 1219, in
EventStruct
out = __main__.output['eventstruct']
KeyError: 'eventstruct'
```

This has caused build issues in openSUSE, as well as Arch Linux, when the
(currently unreleased) eventstruct functionality tries to be used.

Uhm, sorry, but I do not understand this. I have the commit in question, I can
build libxcb against this xcb-proto version, and I can run python -c 'import
xcbgen' without problems. What am I doing wrong?
