2014-05-09vl.c: remove init_clocks call from mainKirill Batuzov
Clocks are initialized in qemu_init_main_loop. They are not needed before it. Initializing them twice is not only unnecessary but is harmful: it results in memory leak and potentially can lead to a situation where different parts of QEMU use different sets of timers. To avoid it remove init_clocks call from main and add an assertion to qemu_clock_init that corresponding clock has not been initialized yet.

2014-05-09block: Fix open flags with BDRV_O_SNAPSHOTKevin Wolf
The immediately visible effect of this patch is that it fixes committing a temporary snapshot to its backing file. Previously, it would fail with a "permission denied" error because bdrv_inherited_flags() forced the backing file to be read-only, ignoring the r/w reopen of bdrv_commit(). The bigger problem this revealed is that the original open flags must actually only be applied to the temporary snapshot, and the original image file must be treated as a backing file of the temporary snapshot and get the right flags for that.

2014-05-09vmdk: Implement .bdrv_get_info()Fam Zheng
This will return cluster_size and needs_compressed_writes to caller, if all the extents have the same value (or there's only one extent).

2014-05-09qemu-img: sort block formats in help messageMike Day
The help message for qemu-img lists the supported block formats, of which there are 27 as of version 2.0.50. The formats are printed in the order of their driver's position in a linked list, which appears random. This patch prints the formats in sorted order, making it easier to read and to find a specific format in the list.

2014-05-09iotests: Use configured pythonMax Reitz
Currently, QEMU's iotests rely on /usr/bin/env to start the correct Python (that is, at least Python 2.4, but not 3). On systems where Python 3 is the default, the user has no clean way of making the iotests use the correct binary. This commit makes the iotests use the Python selected by configure.

2014-05-09qcow2: Fix alloc_clusters_noref() overflow detectionMax Reitz
If the very first allocation has a length of 0, the free_cluster_index is still 0 after the for loop, which means that subtracting one from it will underflow and signal an invalid range of clusters by returning -EFBIG. However, there is no such range, as its length is 0. Fix this by preventing underflows on free_cluster_index during the check.

2014-05-08spice: fix "info spice"Gerd Hoffmann
In case no listening address was specified, "info spice" reports "0.0.0.0" as address. Which is incorrect in case spice is listening on ipv6. Replace it by a wildcard "*" to indicate it is not limited to a specific address. Note: Being more specific is not possible without extending the spice-server api. The socket is handled by spice-server not qemu, so qemu can't easily figure the actual socket address. Reported-by: David Jaša <djasa@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2014-05-07libcacard: replace pstrcpy() with memcpy()Michael Tokarev
Commit 2e679780ae86c6ca8 replaced strncpy() with pstrcpy() in one place in libcacard. This is a qemu-specific function, while libcacard is a stand-alone library (or tries to be). But since we know the exact length of the string to copy, and know that it definitely will fit in the destination buffer, use memcpy() instead, and null-terminate the string after that. An alternative is to use g_strlcpy() or strncpy(), but memcpy() is more than adequate in this place.

2014-05-07tests/tcg: Fix compilation of test_pathPeter Maydell
The test_path binary is (unlike the other test binaries in tests/tcg) actually intended to be compiled with the same compiler used to build the main QEMU executables. It actually #includes a number of the QEMU source files in an attempt to unit-test the util/path.c functions, and so if it is not compiled with the same compiler used by configure to set CONFIG_ settings then it is liable to fail to build. Fix the makefile to build it with the default C compiler rules, not CC_I386, and fix the test itself not to include a lot of unnecessary trace related source files which cause the build to fail if the trace backend is anything other than 'simple'.
