With previous commit we added gspawn-win64-helper-console.exe, required for gspawn() mingw implementation.

2015-11-25qga: Better mapping of SEEK_* in guest-file-seekEric Blake
Exposing OS-specific SEEK_ constants in our qapi was a mistake (if the host has SEEK_CUR as 1, but the guest has it as 2, then the semantics are unclear what should happen); if we had a time machine, we would instead expose only a symbolic enum. It's too late to change the fact that we have an integer in qapi, but we can at least document what mapping we want to enforce for all qga clients (and luckily, it happens to be the mapping that both Linux and Windows use); then fix the code to match that mapping. It also helps us filter out unsupported SEEK_DATA and SEEK_HOLE. In the future, we may wish to move our QGA_SEEK_* constants into qga/qapi-schema.json, along with updating the schema to take an alternate type (either the integer, or the string value of the enum name) - but that's too much risk during hard freeze.

According to the specification: http://pubs.opengroup.org/onlinepubs/9699919799/functions/fopen.html "the application shall ensure that output is not directly followed by input without an intervening call to fflush() or to a file positioning function (fseek(), fsetpos(), or rewind()), and input is not directly followed by output without an intervening call to a file positioning function, unless the input operation encounters end-of-file."

Set fd non-blocking to avoid common use cases (like reading from a named pipe) from hanging the agent. This was missed in the original code. The patch introduces qemu_set_handle_nonoblocking, the local analog of qemu_set_nonblock for HANDLES.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).

2015-09-10error: On abort, report where the error was createdMarkus Armbruster
This is particularly useful when we abort in error_propagate(), because there the stack backtrace doesn't lead to where the error was created. Looks like this: Unexpected error in parse_block_error_action() at .../qemu/blockdev.c:322: qemu-system-x86_64: -drive if=none,werror=foo: 'foo' invalid write error action Aborted (core dumped) Note: to get this example output, I monkey-patched drive_new() to pass &error_abort to blockdev_init(). To keep the error handling boiler plate from growing even more, all error_setFOO() become macros expanding into error_setFOO_internal() with additional __FILE__, __LINE__, __func__ arguments. Not exactly pretty, but it works. The macro trickery breaks down when you take the address of an error_setFOO(). Fortunately, we do that in just one place: qemu-ga's Windows VSS provider and requester DLL wants to call error_setg_win32() through a function pointer "to avoid linking glib to the DLL". Use error_setg_win32_internal() there. The use of the function pointer is already wrapped in a macro, so the churn isn't bad. Code size increases by some 35KiB for me (0.7%). Tolerable. Could be less if we passed relative rather than absolute source file names to the compiler, or forwent reporting __func__.

2015-09-10qga/vss-win32: Document the DLL requires non-null errpMarkus Armbruster
requester.cpp uses this pattern to receive an error and pass it on to the caller (err_is_set() macro peeled off for clarity): ... code that may set errset->errp ... if (errset->errp && *errset->errp) { ... handle error ... } This breaks when errset->errp is null. As far as I can tell, it currently isn't, so this is merely fragile, not actually broken. The robust way to do this is to receive the error in a local variable, then propagate it up, like this: Error *err = NULL; ... code that may set err ... if (err) ... handle error ... error_propagate(errset->errp, err); } See also commit 5e54769, 0f230bf, a903f40.

2015-09-10qga: Clean up unnecessarily dirty castsMarkus Armbruster
qga_vss_fsfreeze() casts error_set_win32() from void (*)(Error **, int, ErrorClass, const char *, ...) to void (*)(void **, int, int, const char *, ...) The result is later called. Since the two types are not compatible, the call is undefined behavior. It works in practice anyway. However, there's no real need for trickery here. Clean it up as follows: * Declare struct Error, and fix the first parameter. * Switch to error_setg_win32(). This gets rid of the troublesome ErrorClass parameter. Requires converting error_setg_win32() from macro to function, but that's trivially easy, because this is the only user of error_set_win32().

2015-09-01qemu-ga: Prevent QEMU-GA VSS provider from being unregistered on MSI reinstallLeonid Bloch
Previously, running the .msi would unregister the QEMU GA VSS service if QEMU GA was already installed on the machine, and then register it only if QEMU GA was NOT previously installed. This behavior caused the service to be registered only after the INITIAL installation, and any subsequent run of the .msi (to redo, repair, or upgrade the installation) ended in the service being unregistered. Now, the VSS service is still unregistered if QEMU GA is already installed (so that a fix or an update could be performed) but then it is registered again (if the GA is not being uninstalled) thus finishing the repair/upgrade correctly. Additionally, downgrading is now prevented. If a user would like to downgrade a version, he/she must uninstall the newer version first.

2015-07-07qga: added GuestPCIAddress informationMichael Roth
PCIAddress inforfation is obtained via SetupApi, which provides the information about address, bus, etc. We look throught entire device tree in the system and try to find device object for given volume. For this PDO SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration for a given devicei if it is possible. This is the most convinient way for a userspace service. The lookup is performed for every volume available. However, this information is not mandatory for vss-provider. In order to use SetupApi we need to notify linker about it. We do not need to install additional libs, so we do not make separate configuration option to use libsetupapi.su SetupApi gives as the same information as kernel driver with IRP_MN_QUERY_INTERFACE. https://support.microsoft.com/en-us/kb/253232 Signed-off-by: Olga Krishtal <okrishtal@virtuozzo.com> Signed-off-by: Denis V.
