Disable problematic tests for miscellaneous causes: * Always fail when building with pbuilder/sbuilder: ~ combined-filter-exclude_uid-drop.sh ~ combined-filter-only_uid-pass.sh ~ datasource_egid.sh ~ datasource_egroup.sh * The following test does not work reliably(causing random FTBFS), presumably because of a high load of the build servers: ~ datasource_timestamp_us.sh * The following tests have caused build failures on some architectures (spark64, alpha), probably because of some unique setup on the buildd and wrong assumptions about the format of thread identification: ~ datasource_tid.sh ~ datasource_tid_kernel.sh ~ datasource_login.sh * The following test always fails on salsa pipeline because the test itself and the tested code datasource\rpname.c handle differently the situation, when process parent pid is 0. With salsa pipeline we have this rare case, that the test is invoked in a process tree, with root process id equal to 0. ~ datasource_rpname.sh
