* qemu-option: Clean up fragile use of error_is_set()Markus Armbruster2014-05-091-1/+1
| | | | | | | | | | | | | | | | | | | Using error_is_set(ERRP) to find out whether to bail out due to previous error is either wrong, fragile, or unnecessarily opaque. It's wrong when ERRP may be null, because errors go undetected when it is. It's fragile when proving ERRP non-null involves a non-local argument. Else, it's unnecessarily opaque (see commit 84d18f0). The error_is_set(state->errp) in qemu_opts_from_qdict_1() is merely fragile, because the callers never pass state argument with null state->errp. Make the code more robust and more obviously correct: test *state->errp directly.

| | | | | | | | | | | | glib >= 2.31 always enables thread support and g_thread_supported() is #defined to 1, there's no need to call g_thread_init() anymore, and it definitely does not need to report error which never happens.

* osdep: initialize glib threads in all QEMU toolsStefan Hajnoczi2014-03-251-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | glib versions prior to 2.31.0 require an explicit g_thread_init() call to enable multi-threading. Failure to initialize threading causes glib to take single-threaded code paths without synchronization. For example, the g_slice allocator will crash due to race conditions. Fix this for all QEMU tool programs (qemu-nbd, qemu-io, qemu-img) by moving the g_thread_init() call from vl.c:main() into a new osdep.c:thread_init() constructor function. thread_init() has __attribute__((constructor)) and is automatically invoked by the runtime during startup. We can now drop the "simple" trace backend's g_thread_init() call since thread_init() already called it. Note that we must keep coroutine-gthread.c's g_thread_init() call which is located in a constructor function. There is no guarantee for constructor function ordering so thread_init() may only be called later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QemuMutex does not guarantee fairness and cannot be acquired recursively: Fairness means each locker gets a turn and the scheduler cannot cause starvation. Recursive locking is useful for composition, it allows a sequence of locking operations to be invoked atomically by acquiring the lock around them. This patch adds RFifoLock, a recursive lock that guarantees FIFO order. Its first user is added in the next patch. RFifoLock has one additional feature: it can be initialized with an optional contention callback. The callback is invoked whenever a thread must wait for the lock. For example, it can be used to poke the current owner so that they release the lock soon. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

* | Use error_is_set() only when necessaryMarkus Armbruster2014-02-172-19/+19
|/ | | | | | | | | | | | | | | | error_is_set(&var) is the same as var != NULL, but it takes whole-program analysis to figure that out. Unnecessarily hard for optimizers, static checkers, and human readers. Dumb it down to obvious. Gets rid of several dozen Coverity false positives. Note that the obvious form is already used in many places.

| | | | | | | | | | | | | | The patch adds functions fifo8_push_all() and fifo8_pop_buf() which can be used respectively to push the content of a memory buffer to the fifo and to pop multiple bytes obtaining a pointer to the fifo backing buffer. In addition, it implements fifo8_num_free() and fifo8_num_used() which allow to check if a multi-byte operation can be performed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function basically parses command-line options given as a QDict replacing a config file. For instance, the QDict {"section.opt1": 42, "section.opt2": 23} corresponds to the config file: [section] opt1 = 42 opt2 = 23 It is possible to specify multiple sections and also multiple sections of the same type. On the command line, this looks like the following: inject-error.0.event=reftable_load,\ inject-error.1.event=l2_load,\ set-state.event=l1_update This would correspond to the following config file: [inject-error "inject-error.0"] event = reftable_load [inject-error "inject-error.1"] event = l2_load [set-state] event = l1_update Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

* error: Don't use error_report() for assertion msgs.Peter Crosthwaite2014-01-151-4/+4
| | | | | | | | | | | | | | | | | | | Use fprintf(stderr instead. This removes dependency of libqemuutil.a on the monitor. We can further justify this change, in that this code path should only trigger under a fatal error condition. fprintf-stderr is probably the appropriate medium as under a fatal error conidition the monitor itself may be down and out for the count. So assertion failure messages should go lowest common denominator - straight to stderr. Fixes the build as reported by Kevin Wolf. Issue debugged and change suggested by Luiz Capitulino.
