Joseph Crowell 82909ceadf ci: check-symbols: find server libraries, don't cancel driver jobs 
ldd now searches the server's libdir, so libraries installed with the
server (libdrm in CI) are not reported as missing server symbols, and a
library still not found exits 2. One failing driver job no longer
cancels the others.

Driver ABI check tools

Scripts that let any Xorg module check itself against staged XLibre servers. They are installed with the server SDK; find them with:

pkg-config --variable=abi_tools_dir xorg-server

Each server is built with debug info and staged under ABI_WORK with DESTDIR, so nothing is installed into the system.

Script What it checks
run-matrix.sh Builds the module against every server in ABI_SERVERS and checks that every server symbol it needs is exported by each of them (built for one release, loaded into another).
gate-driver.sh Builds the committed tree (BEFORE_REF, default HEAD) and the working tree against each server, and fails if libabigail reports a changed layout of a server type the module uses.
check-symbols.sh One module against one staged server, or with --prefix <dir> one installed in <dir>; also fails a module linked with BIND_NOW that needs symbols only other modules define.
abigail-compare.sh One libabigail comparison; added types pass, removed symbols and changed layouts fail; --allow TYPE accepts a known change.
check-private-includes.py For meson modules: every server-internal header a source file includes must be needed by it.

build-server.sh, build-driver.sh, staged-pc.sh and common.sh are the helpers the scripts above use.

Environment

  • ABI_WORK: work directory (required); put it on disk, the servers take a few hundred MB each.
  • ABI_MODULE: the module inside a build directory, for run-matrix.sh and gate-driver.sh: src/<name>_drv.so for meson, src/.libs/<name>_drv.so for autotools.
  • ABI_DRIVER_SRC: the module's source tree (default: the git top level of the current directory).
  • ABI_SERVERS: server branches or tags (default: release/25.0 release/25.1 release/25.2 master).
  • XSERVER_SRC: a local xserver clone to take sources from instead of cloning from GitHub; XSERVER_REMOTE names its upstream remote.

Example, from a meson driver's source tree:

tools=$(pkg-config --variable=abi_tools_dir xorg-server)
ABI_WORK=$HOME/abi-work ABI_MODULE=src/amdgpu_drv.so "$tools/run-matrix.sh"
ABI_WORK=$HOME/abi-work ABI_MODULE=src/amdgpu_drv.so "$tools/gate-driver.sh"

Needs meson, ninja, git, pkg-config, binutils (nm) and libabigail (abidiff); autotools modules also need autoconf, automake and libtool.
