* Args.c: fix clipboard=0 or -clipboard 0Ulrich Sibiller2019-11-151-1/+1
| | | | This should disable clipboard but effictively did activate clipboard=both.
* Args.c: remove unreachable codeUlrich Sibiller2019-11-151-24/+0
| | | | | | Right at the beginnigng of nxagentParseSingleOption we check for "clipboard" and prepare argv and argc accordingly for ddxProcessArgument. The removed code thus could never be reached.
* Args.c: fix unitialized variableUlrich Sibiller2019-11-151-0/+1
| | | | | | | "clipboard=something" does not need to be passed on, so return after setting nxagentOptions accordingly. This fixes [nx-X11/programs/Xserver/hw/nxagent/Args.c:1584]: (error) Uninitialized variable: argc
* NXglxext.c: use upstream versions of Dispatch functionsUlrich Sibiller2019-11-022-56/+5
| | | | | | | | | instead of a full copy. We still have our own function because we need to handle the nxagentGlxTrap. This trap is now set before the start of the dispatcher while it has been set only directly before calling the dispatched function. Saves ~50 duplicated lines.
* NXwindow.c: use upstream function DeleteWindow()Ulrich Sibiller2019-11-022-52/+0
| | | | | | | DeleteWindow() is calling FreeWindowResources() which is calling DisposeWindowOptional() which sets pWin->optional to NULL. So the now removed code was never called. After removal DeleteWindow() is identical to the dix version, so we use that one.

* Simplify (NX)xvdisp.cUlrich Sibiller2019-11-023-148/+15
| | | | | | | | | | NXxvdisp.c only exists to set/unset nxagentXvTrap before/after dispatch. There's no need to duplicate the original code. We now rename the original dispatch functions and call them in our dispatch code. Also drop check for sun and cygwin, as they never appeared in xorg upstream code.

* nxagent: drop NXextension.cUlrich Sibiller2019-11-024-33/+2
| | | | | instead of including it and creating NXextension.o we can simply use the dix version. There are no NX specials anymore.

* damage: Don't rewrite Text ops to GlyphBlt opsUlrich Sibiller2019-11-012-226/+19
| | | | | | | | | | | | | | | | | | | | | | | | | This backport of a 2013 Xorg fix changes miext/damage.c so that the text functions (damageText, damage{Poly,Image}Text{8,16}) finally are very similar to the changes that NX introduced in 2007 with nxagent-3.0.0-28. Fun fact: the original freedesktop bug mentioned below is from 2005 and the fix came in 2013... Next commit will be the complete drop of NXdamage.c. commit 0f3f8e4295d4c05f33b93e0ffd2f6f8cd5759bf7 Author: Adam Jackson <ajax@redhat.com> Date: Wed Aug 21 11:13:11 2013 -0400 damage: Don't rewrite Text ops to GlyphBlt ops There's no particularly good reason to, and it breaks Xnest.

Unfortunately, nxagent (and libXcompshad) require a modified libX11 version, nicknamed libNX_X11, for proper functioning. Fortunately, this one can act as a drop-in replacement for the system libX11. So we’ll hack our way out: add a DT_NEEDED entry for libX11 by linking against the system library when building nxagent and link the other system libraries later and set DT_RUNPATH to a special directory containing symlinks from libNX_X11 to libX11. This tricks the loader into pulling in the "fake" libX11 version without checking its SONAME and thus satisfying the DT_NEEDED entry early on - specifically also for the system libraries. Ex.: readelf -a /usr/bin/nxagent | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [libX11.so.6] ... 0x0000000000000001 (NEEDED) Shared library: [libNX_X11.so.6] ... If, however, you run the build a second time, it will find the newly created libX11 links in ../../exports/lib (used as an additional library search path) instead of the system libX11. The results in a binary looking like this: 0x0000000000000001 (NEEDED) Shared library: [libNX_X11.so.6] ... With such a setup, the whole magic falls apart and system libraries will suddenly pull in the actual system libX11 file. We initially believed a compiler call such as: ${CC} [--unrelated-options ...] [-Lunrelated_library_path ...] -lX11 [more options like -l and -L] -L../../exports/lib -lother_libraries to do "the right thing" and link against the system libX11 (or, at worst, a libX11 found in the library directory search list preceding the link call) and use ../../exports/lib only for later linking operations, since the order of options matters. However, this turned out to be blatantly wrong: while the order of -L arguments does matter for building the search path, the whole search path including elements from *ALL* -L arguments (and the system paths) will always be used when linking libraries. Hence, (counter-intuitively to us) both these calls will be equivalent: ${CC} [--unrelated-options ...] -la -Loverride_liba -lb [-Lunrelated_library_path ...] -lc ${CC} [--unrelated-options ...] -Loverride_liba [-Lunrelated_library_path ...] -la -lb -lc By removing LDPRELIBS from NXAGENTSYSLIBS, ../../exports/lib is no longer used during building/linking and the binaries are built reproducibly. We never intended to use this directory at link time anyway.
