The libvirtd daemon had a few crude system tap probes. Some of
these were broken during the RPC rewrite. The new modular RPC
code is structured in a way that allows much more effective
tracing. Instead of trying to hook up the original probes,
define a new set of probes for the RPC and event code.
The master probes file is now src/probes.d. This contains
probes for virNetServerClientPtr, virNetClientPtr, virSocketPtr
virNetTLSContextPtr and virNetTLSSessionPtr modules. Also add
probes for the poll event loop.
The src/dtrace2systemtap.pl script can convert the probes.d
file into a libvirt_probes.stp file to make use from systemtap
much simpler.
The src/rpc/gensystemtap.pl script can generate a set of
systemtap functions for translating RPC enum values into
printable strings. This works for all RPC header enums (program,
type, status, procedure) and also the authentication enum
The PROBE macro will automatically generate a VIR_DEBUG
statement, so any place with a PROBE can remove any existing
manual DEBUG statements.
* daemon/libvirtd.stp, daemon/probes.d: Remove obsolete probing
* daemon/libvirtd.h: Remove probe macros
* daemon/Makefile.am: Remove all probe buildings/install
* daemon/remote.c: Update authentication probes
* src/dtrace2systemtap.pl, src/rpc/gensystemtap.pl: Scripts
to generate STP files
* src/internal.h: Add probe macros
* src/probes.d: Master list of probes
* src/rpc/virnetclient.c, src/rpc/virnetserverclient.c,
src/rpc/virnetsocket.c, src/rpc/virnettlscontext.c,
src/util/event_poll.c: Insert probe points, removing any
DEBUG statements that duplicate the info
'./autobuild.sh' with lcov installed discovered that our
coverage support has been bit-rotting for a while. This
restores it back to a successful state, although I have
not yet spent any time looking through the resulting files to
look for low-hanging fruit in the unit test coverage front.
* configure.ac: Clear COMPILER_FLAGS at right place.
* Makefile.am (cov): Newer genhtml no longer likes plain -s.
* m4/compiler-flags.m4 (gl_COMPILER_FLAGS): Don't AC_SUBST
COMPILER_FLAGS; it is a shell variable for use in configure only.
* src/Makefile.am (AM_CFLAGS, AM_LDFLAGS): New variables, to make
it easier to provide global flag additions. Use throughout, to
uniformly apply coverage flags.
* .gitignore: Globally ignore gcov output.
* daemon/.gitignore: Simplify.
* src/.gitignore: Likewise.
* tests/.gitignore: Likewise.
Move the virsh tool and its man page into the tools directory
* Makefile.am: Remove rules for virsh.1 man page
* virsh.1: Remove auto-generated file
* docs/Makefile.am: Remove rules for virsh.pod man page
* docs/virsh.pod: Move to tools/ directory
* src/Makefile.am, src/.gitignore: Remove rules for virsh
* src/console.c, src/console.h, src/*.ico, src/virsh_win_icon.rc,
src/virsh.c: Move into tools/ directory
* tools/Makefile.am: Add rules for building virsh
* tools/.gitignore: Ignore virsh built files
* tests/virshtest.c, tests/int-overflow: Update for new
virsh location
* Makefile.maint (sync-vcs-ignore-files): New target.
