2015-06-19qom: Don't pass string table to object_get_enum() functionDaniel P. Berrange
Now that properties can be explicitly registered as an enum type, there is no need to pass the string table to the object_get_enum() function. The object property registration already has a pointer to the string table. In changing this method signature, the hostmem backend object has to be converted to use the new enum property registration code, which simplifies it somewhat. Signed-off-by: Daniel P.

2015-06-19qom: Add an object_property_add_enum() helper functionDaniel P. Berrange
A QOM property can be parsed as enum using the visit_type_enum() helper function, but this forces callers to use the more complex generic object_property_add() method when registering it. It also requires that users of that object have access to the string map when they want to read the property value. This patch introduces a specialized object_property_add_enum() method which simplifies the use of enum properties, so the setters/getters directly get passed the int value. typedef enum { MYDEV_TYPE_FROG, MYDEV_TYPE_ALLIGATOR, MYDEV_TYPE_PLATYPUS, MYDEV_TYPE_LAST } MyDevType; Then provide a table of enum <-> string mappings static const char *const mydevtypemap[MYDEV_TYPE_LAST + 1] = { [MYDEV_TYPE_FROG] = "frog", [MYDEV_TYPE_ALLIGATOR] = "alligator", [MYDEV_TYPE_PLATYPUS] = "platypus", [MYDEV_TYPE_LAST] = NULL, }; Assuming an object struct of typedef struct { Object parent_obj; MyDevType devtype; ...other fields... } MyDev; The property can then be registered as follows: static int mydev_prop_get_devtype(Object *obj, Error **errp G_GNUC_UNUSED) { MyDev *dev = MYDEV(obj); return dev->devtype; } static void mydev_prop_set_devtype(Object *obj, int value, Error **errp G_GNUC_UNUSED) { MyDev *dev = MYDEV(obj); dev->devtype = value; } object_property_add_enum(obj, "devtype", mydevtypemap, "MyDevType", mydev_prop_get_devtype, mydev_prop_set_devtype, NULL); Note there is no need to check the range of 'value' in the setter, because the string->enum conversion code will have already done that and reported an error as required.

2015-06-19qom: Add object_new_with_props() / object_new_withpropv() helpersDaniel P. Berrange
It is reasonably common to want to create an object, set a number of properties, register it in the hierarchy and then mark it as complete (if a user creatable type). This requires quite a lot of error prone, verbose, boilerplate code to achieve. First a pair of functions object_set_props() / object_set_propv() are added which allow for a list of objects to be set in one single API call. Then object_new_with_props() / object_new_with_propv() constructors are added which simplify the sequence of calls to create an object, populate properties, register in the object composition tree and mark the object complete, into a single method call. Usage would be: Error *err = NULL; Object *obj; obj = object_new_with_propv(TYPE_MEMORY_BACKEND_FILE, object_get_objects_root(), "hostmem0", &err, "share", "yes", "mem-path", "/dev/shm/somefile", "prealloc", "yes", "size", "1048576", NULL); Note all property values are passed in string form and will be parsed into their required data types, using normal QOM semantics for parsing from string format.

2015-06-12iotests: Add tests for overriding BDRV_O_PROTOCOLMax Reitz
This adds tests for overriding the qemu-internal BDRV_O_PROTOCOL flag by explicitly specifying a block driver. As one test must be run over the NBD protocol while the other must not, this patch adds two separate iotests. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2015-06-12block: driver should override flags in bdrv_open()Max Reitz
The BDRV_O_PROTOCOL flag should have an impact only if no driver is specified explicitly. Therefore, if bdrv_open() is called with an explicit block driver argument (either through the options QDict or through the drv parameter) and that block driver is a protocol block driver, BDRV_O_PROTOCOL should be set; if it is a format block driver, BDRV_O_PROTOCOL should be unset. While there was code to unset the flag in case a format block driver has been selected, it only followed the bdrv_fill_options() function call whereas the flag in fact needs to be adjusted before it is used there. With that change, BDRV_O_PROTOCOL will always be set if the BDS should be a protocol driver; if the driver has been specified explicitly, the new code will set it; and bdrv_fill_options() will only "probe" a protocol driver if BDRV_O_PROTOCOL is set. The probing after bdrv_fill_options() cannot select a protocol driver. Thus, bdrv_open_image() to open BDS.file is never called if a protocol BDS is about to be created. With that change in turn it is impossible to call bdrv_open_common() with a protocol drv and file != NULL, which allows us to remove the bdrv_swap() call. This change breaks a test case in qemu-iotest 051: "-drive file=t.qcow2,file.driver=qcow2" now works because the explicitly specified "qcow2" overrides the BDRV_O_PROTOCOL which is automatically set for the "file" BDS (and the filename is just passed down). Therefore, this patch removes that test case. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2015-05-22qtest: Add base64 encoded read/writeJohn Snow
For larger pieces of data that won't need to be debugged and viewing the hex nibbles is unlikely to be useful, we can encode data using base64 instead of encoding each byte as %02x, which leads to some space savings and faster reads/writes. For now, the default is left as hex nibbles in memwrite() and memread(). For the purposes of making qtest io easier to read and debug, some callers may want to specify using the old encoding format for small patches of data where the savings from base64 wouldn't be that profound. memwrite/memread use a data encoding that takes 2x the size of the original buffer, but base64 uses "only" (4/3)x, so for larger buffers we can save a decent amount of time and space.

Write to one guest, migrate, and then read from the other. adjust ahci_io to clear any buffers it creates, so that we can use ahci_io safely on both guests knowing we are using empty buffers and not accidentally re-using data.

2015-05-22qtest/ahci: Add migration testJohn Snow
Notes: * The migration is performed on QOSState objects. * The migration is performed in such a way that it does not assume consistency between the allocators attached to each. That is to say, you can use each QOSState object completely independently and then at an arbitrary point decide to migrate, and the destination object will now be consistent with the memory within the source guest. The source object that was migrated from will have a completely blank allocator. ahci-test.c: - verify_state is added - ahci_migrate is added as a frontend to migrate - test_migrate_sanity test case is added.

2015-05-22qemu-iotests: Make debugging python tests easierFam Zheng
Adding "-d" option. The output goes to "tee" so it appears in your console. Also, raise the verbosity of unnitest runner. When testing a topic branch, it's possible that a bug introduced by a code change makes the python test case hang, with debug output, it is much easier to locate the problem. This can also be helpful if you want to watch the progress of a python test, it offers you a way to sense the speed of each test case method you're writing. Note: because there is no easy way to get *both* the verbose output and the output expected by ./check comparison, the case would always fail with an "output mismatch". The sole purpose of using this option is giving developers a quick way to debug when things go wrong.
