Hi all,
I am the Outreachy (called before OP, OPW) participant for Xorg
(www.x.org/wiki/XorgOPW/ <http://www.x.org/wiki/XorgOPW/>) for project
"Server-side XCB", my task is to write generator for swapping and
size-checking functions and integrate the generated code into Xsever.
Here is the link tobitbucket <bitbucket.org/AsalleKim/gen_swap_check>. I
didn't create patch, because in my opinion it's pretty inconvenient to
send patches with code written from scratch, though it's a powerful tool
for maintaining already existing code. The repo contains forked xserver
from main xserver repo <http://cgit.freedesktop.org/xorg/xserver/>. It
uses some changes in xcb made by Christian Linhart and Jaya Tiwari, the
changes are in pending patches and will be soon applied (if they are not
already). This mainly touches the valueparam to switch replacement in
xproto.xml.
As valueparam is deprecated, the generator, I am working on, does not
support it.
Generator's code can process almost all extensions, but I am now mainly
working on Shape and Xproto.
For now it creates source file and header file in the directory
proto/gen and then they are built with automake (proto/Makefile.am).
There are several things I was not sure about.
1. The working name of the swapping and size-checking functions
generator is gen_swap_check, which is rather awkward. But I couldn't
invent anything better.
2. To test the code I need to integrate it to the xserver. I already
made some changes into Xext/shape.c so it uses the generated code now.
The Xext/shape.h must include the swapcheck_shape.h (generated one).
Would it be okay if I copy all generated headers to
{installdir}/include/xcb, mixing the genswap-generated code and the
regular code, generated by c_client.py? And copy the compiled
swapcheck_* files to {installdir}/lib.
3. proto/Makefile.am is written in such way that no make targets are
declared. How can I add cp commad to it?
4. When building several warnings in included file os.h appeared. How
can I get rid of them? Or should I ignore them?
/home/asalle/xorg/Debug2/test-install/include/xorg/os.h:541:1: warning:
redundant redeclaration of 'strndup' [-Wredundant-decls]
1055 strndup(const char *str, size_t n);
This is the short overview of swapping and size-checking functions
generator,
I would be glad to hear your comments and messages about found bugs,
Asalle
