iLiad libX11.so.6, auto refresh

[hansel]

Hi All,

How does the 'auto refresh' version of libX11.6.so work exactly? Are the sources available somewhere?

I'm trying to make an app with the 'normal' lib, but I think I'm missing some steps...

Thnx, Hnsl.

There used to be sources here: http://projects.mobileread.com/iliad/

It was antartica's project. I believe he's working on a different update manager now.

See here: https://dev.mobileread.com/trac/xepdmgr/wiki

Adam is right. Sources for the patch to libX11 are here:
http://projects.mobileread.com/iliad...0061203-2.diff

The patched libX11 follows the early work of scotty1024 to document the way to refresh the display on the iliad.

And Adam is also right about xepdmgr. The patched libX11 helps but has a lot of irritating limitations, hence xepdmgr. But right now I'm stuck compiling the needed libxdamage for the iliad. If all goes well, xepdmgr will not have library dependencies and be a lot smaller than the patched libX11... it's a work in progress :-).

P.S.: Well, xepdmgr will depend on liberdm, as we don't know (yet) how to do the updates directly O:-)

Thanks!
One more thing to explore...

I like your 'repair daemon' idea! It will stop eating cpu when nothing changes...

Still stuck with libXdamage? I managed to compile libXdamage-1.1.1 for the Iliad (as an exercise, inside scratchbox). The dependencies are a nightmare / challenge ;-) I didn't test it yet with your 'proof of concept'.

This is what I did, I hope it helps you in your quest! (approx, I'm not sure I logged everything)

./dl-and-install.sh xfixes.h
./dl-and-install.sh xinerama.xml        #xcb-proto_1.1
get libpthread-stubs_0.1.orig.tar.gz & patch
./dependencies-helper/unpack-n-patch-n-build-install.sh libpthread-stubs_0.1.orig.tar.gz
./dl-and-install.sh xslt.h              #libxcb-1.1/
./dl-and-install.sh Xext.h              #not sure if this one is needed
./dl-and-install.sh xfixesproto.h
./dl-and-install.sh Xfixes.h
./dl-and-install.sh libXdamage.so

The resulting dependencies (in scratchbox) are:

[sbox-iliad: /usr/local/lib] > ldd libXdamage.so
        libXfixes.so.3 => libXfixes.so.3 (0x00000000)
        libX11.so.6 => libX11.so.6 (0x00000000)
        libc.so.6 => /lib/libc.so.6 (0x00000000)
        libXau.so.6 => libXau.so.6 (0x00000000)
        libXdmcp.so.6 => libXdmcp.so.6 (0x00000000)
        libdl.so.2 => /lib/libdl.so.2 (0x00000000)
        liberdm.so.2 => liberdm.so.2 (0x00000000)
        liberipc.so.0 => liberipc.so.0 (0x00000000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00000000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00000000)

I attach libXdamage.so.1.1.0 (it's quite small)

Hi All,

I did some tests...
- I can confirm that Antartica's 'proof of concept' xedpmgr compiles an links fine
- the resulting executable (statically linked, without extra dependencies) is 23Kb (this is all you need to start apps)
- IT WORKS!!! It refreshes the display in an acceptable way
- This will change the way software is developed for Ilads

Antartica:
- GREAT IDEA!!! CONGRATS!!!
- maybe you can start a new thread to discuss the algorithm for combining rectangles (choice between full an typing update)?

I've managed to get my "prunned" libx11 for xepdmgr. The unstripped statically linked executable of xepdmgr is 299245 bytes, and that is without the dependency on libX11.so:

[sbox-iliad: /shared/Devel/iliad/src.xepdmgr/xepdmgr-1.0-iliad] > ldd xepdmgr
        liberdm.so.2 => /usr/local/lib/liberdm.so.2 (0x00000000)
        libc.so.6 => /lib/libc.so.6 (0x00000000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00000000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00000000)
[sbox-iliad: /shared/Devel/iliad/src.xepdmgr/xepdmgr-1.0-iliad] > ls -l xepdmgr
-rwxrwxr-x  1 dario dario 299245 Sep 20 13:55 xepdmgr

P.S.: Thanks for testing it on the iliad and the success report! I'm VERY happy :-b. See the other thread on xepdmgr for my final code.

Ok. I start another thread for it :-).
