Extensions could previously declare initialisation dependencies on other
extensions, which would then get nicely sorted by the loader. We only
had one user for this, GLX, which had one pointless (Composite) and one
possibly useful dependency (DBE). As DBE is now a built-in, it will
always be sorted by GLX, so we no longer have any users for it.

LoaderSymbol calls dlsym with RTLD_DEFAULT pseudo handle making it search in

It's used in doLoadModule to locate <modulename>ModuleData symbol, the
module's library gets the flag and is kept in memory even after it is
unloaded.
This patch adds LoaderSymbolFromModule function that looks for symbol only in

If the platform provides vasprintf() we simply wrap it, otherwise we

Since not all platforms guarantee to NULL out the return pointer on
failure, we don't either, and require callers to check the return
value for -1.
The old Xprintf() API is deprecated, but left for compatibility for now.

The basic trigger operation added here triggers
relative to a given X screen's rendering operations.
To perform this operation, fence sync objects must
be tied to a screen. As Aaron Plattner pointed out,
screens are identified but a drawable in X protocol,
so a drawable argument is included in
XSyncCreateFence(). The screen also could have been
specified as part of the trigger operation. However,
it is also desireable to associate a screen with
fence sync objects at creation time so that the
associated screen's driver can allocate any HW-

Whoops, please revert this patch -- overlay is in use in nvidia drivers,
and it's too late in release cycle to remove it.
I feel really sorry that I kept this patch in my tree. I will submit
another one, removing only XAA overlay hooks which are not used at all.
The only reference to it in server and drivers is in XAA overlay code which
would segfault as no miInitOverlay is called ever. No segfaults were observed
"in wild", so XAA overlay is probably also unused.
XAA code is modified to act as if miOverlayCopyUnderlay always returned false,
because XAACopyWindow8_32 could only set doUnderlay to true if it's called from
miOverlayMoveWindow or miOverlayResizeWindow, which can only be called if
miInitOverlay has hooked those functions, and no driver (on fd.o) or server code
calls that.

Since it is already parsing cpp output, create a dependency file
in the same process. This will cause sdksyms.c to be regenerated
whenever a sdk header is modified.
This also uses the gmake 'sinclude' directive (don't fail if
included file doesn't exist). This should not cause any problems
given that gmake only constructs are used in several other Makefiles.
- Pass $(CPP) & $(AWK) settings from configure to sdksyms.sh
- Only reset sdk variable (tracks if header is part of sdk) if
a filename is included on the cpp # <line-no> <filename> line,
since Sun compilers omit filename when it is unchanged from
previous line.
Ubuntu uses mawk by default, but it doesn't understand posix character
classes (which are locale dependent, and this patch uses only valid C
identifiers).
Also make sure awk runs with LC_ALL=C to match the regex patterns.
If the basename of header file processed by cpp matches $top_srcdir,
check for extern symbols in the output, and add to the xorg_symbols
vector.
Possibly a better solution then using this script would be to somehow
tell the linker to not drop any symbols from the binary being generated.
Thanks to David Miller for noticing a make problem with sdksyms.c
not being regenerated when sdksyms.sh is updated. This is not yet the
best solution; automake generates dependency for sdksyms.o, but the
build really should also regenerate sdksyms.c when sdksyms.o needs to
be regenerated.
Export the symbols in miext/cw/cw.h. These symbols are in libxaa, and
at least the nvidia driver uses them. Maybe cw.h should be installed
in the sdk.
The awk script was incorrectly referencing the struct name, and
not the struct variable.
Also added some comments to sdksyms.sh, for the reason it generates
the "symbol table" and add a message to the generated file, telling
is was automatically generated.
Traditional posix awk doesn't know about \W and whilst we check that
awk exists in configure.ac we don't check which awk we are using.
This corrects symbol generation for posix only awk.
All .a libraries were converted to .la, and instead of linking the
Xorg binary with a mix of .a and .la, and adding some libraries more
then once in the command line, etc, now it generates a single libxorg.la
from all the required convenience libraries, and links with a dummy
xorg.c (that should usually be the file with the main function...).
This removes the requirement of some things like libosandcommon and
libinit, that existed to circumvent problems when linking multiple
.a and .la in the final Xorg binary.
The "symbol table" is now generated dynamically, by a shell script,
with an embedded gawk parser that parses cpp output. The new file
sdksyms.sh is generated by hand by analyzing all Makefile.am's and
making it create a sdksyms.c file, that includes all sdk headers that
will add symbols for the Xorg binary. Module headers aren't read, and
a in 2 files it was required to add a "<hash>ifndef XorgLoader" around
declarations shared between the Xorg binary and libextmod. A few
other changes were added to other sdk headers, like preventing
multiple inclusion, or including other headers to satisfy dependencies.
This should be a lot more portable, and better (hopefully properly)
using libtool to generate convenience libraries.
If not taking the symbol addresses, linkage will break badly, as not
all symbols will be present, and it also requires changing library order,
and/or making some changes like the "libosandcommon".
This table should be modified to be generated automatically, as
it is required to "fool" the compiler/loader into adding all required
symbols to the X Server.
Those tables were once used to decide what symbols are visible to
modules, but they were outdated. The only real usage was that, since
it was taking the address of symbols, linkage should fail if the
symbols were not available.
Now the proper way to make symbols available to modules should
be to use the _X_EXPORT macro, or not compile with hidden symbols,
so that all symbols would be available.
All symbols in the tables were revised to ensure they are exported,
and only symbols that were not exported are ClientSleepUntil() and
DuplicateModule(), that were not in the sdk for quite some time
already, and should not have any users outside of the X Server
(and/or builtin modules).
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
This is done to actually change DIX_CFLAGS, as not all "modules" use
XORG_CFLAGS.
Also export the symbols that are required by other modules after
the change.
These symbols were removed from the X Server, or never declared.
One symbol that may need special attention is XkbBuildCoreState(),
that doesn't have a prototype anywhere, but is called from
xkb/xkbEvents.c:XkbFilterEvents(), and also used by the macros
XkbStateFieldFromRec() and XkbGrabStateFromRec() defined in
include/xkbstr.h.
fb/wfbrename.h also may need some cleanup, as it makes several
"renames" of non existing symbols.
