2013-03-28qcow2: Gather clusters in a looping loopKevin Wolf
Instead of just checking once in exactly this order if there are dependendies, non-COW clusters and new allocation, this starts looping around these. This way we can, for example, gather non-COW clusters after new allocations as long as the host cluster offsets stay contiguous. Once handle_dependencies() is extended so that COW areas of in-flight allocations can be overwritten, this allows to continue with gathering other clusters (we wouldn't be able to do that without this change because we would have missed a possible second dependency in one of the next clusters). This means that in the typical sequential write case, we can combine the COW overwrite of one cluster with the allocation of the next cluster as soon as something like Delayed COW gets actually implemented. It is only by avoiding splitting requests this way that Delayed COW actually starts improving performance noticably.

2013-03-28qcow2: Fix "total clusters" number in bdrv_checkKevin Wolf
This should be based on the virtual disk size, not on the size of the image. Interesting observation: With some VM state stored in the image file, percentages higher than 100% are possible, even though snapshots themselves are ignored. This is a qcow2 bug to be fixed another day: The VM state should be discarded in the active L2 tables after completing the snapshot creation.

A comment explains that -nographic hangs test case 007. This is no longer the case so add -nographic. This makes the test suite faster and more pleasant to run since no windows pop up. I am not sure exactly when -nographic starting working for this case but there is no fundamental reason why graphics are needed here.

Now that each AioContext has a ThreadPool and the main loop AioContext can be fetched with bdrv_get_aio_context(), we can eliminate the concept of a global thread pool from thread-pool.c. The submit functions must take a ThreadPool* argument. block/raw-posix.c and block/raw-win32.c use aio_get_thread_pool(bdrv_get_aio_context(bs)) to fetch the main loop's ThreadPool. tests/test-thread-pool.c must be updated to reflect the new thread_pool_submit() function prototypes.

2013-02-07tests/test-string-input-visitor: Handle errors provoked by fuzz testPeter Maydell
It's OK and expected for visitors to return errors when presented with the fuzz test's random data. Since the fuzzer doesn't care about errors, we pass in NULL rather than an Error**. This fixes a bug in the fuzzer where it was passing the same Error** into each visitor, with the effect that once one visitor returned an error, each later visitor would notice that it had been passed in an Error** representing an already set error, and do nothing. For the case of visit_type_str() we also need to handle the case where an error means that the visitor doesn't set our char*. We initialize the pointer to NULL so we can safely g_free() it regardless of whether the visitor allocated a string for us or not. This fixes a problem where this test failed the MacOSX malloc() consistency checks and might segfault on other platforms [due to calling free() on an uninitialized pointer variable when visit_type_str() failed.].

2013-02-04cutils: unsigned int parsing functionsEduardo Habkost
There are lots of duplicate parsing code using strto*() in QEMU, and most of that code is broken in one way or another. Even the visitors code have duplicate integer parsing code[1]. This introduces functions to help parsing unsigned int values: parse_uint() and parse_uint_full(). Parsing functions for signed ints and floats will be submitted later. parse_uint_full() has all the checks made by opts_type_uint64() at opts-visitor.c: - Check for NULL (returns -EINVAL) - Check for negative numbers (returns -EINVAL) - Check for empty string (returns -EINVAL) - Check for overflow or other errno values set by strtoll() (returns -errno) - Check for end of string (reject invalid characters after number) (returns -EINVAL) parse_uint() does everything above except checking for the end of the string, so callers can continue parsing the remainder of string after the number. Unit tests included. [1] string-input-visitor.c:parse_int() could use the same parsing code used by opts-visitor.c:opts_type_int(), instead of duplicating that logic.

We've seen this repeatedly in buildbot but I can now reliably reproduce it myself too. With a few hundred runs of 'make check', qemu-system-sparc will hang consuming 100% CPU. I've attached GDB to the hung process and unfortunately, I can't get anything useful out of GDB (RIP is not a valid simple and there is nothing else on the stack).

When running "make check" with gcov enabled, we get the following message: hw/tmp105.gcda:cannot open data file, assuming not executed The problem happens because: * tmp105-test exits before QEMU exits, because waitpid() at qtest_quit() fails; * waitpid() fails because there's another process already waiting for the QEMU process; * The process that is already waiting for QEMU is the child created by qtest_init() to run system(); * qtest_quit() is incorrectly waiting for the QEMU PID directly instead of the child created by qtest_init().
