2016-10-06rules.mak: quiet-command: Split command name and args to printPeter Maydell1-3/+3
The quiet-command make rule currently takes two arguments: the command and arguments to run, and a string to print if the V flag is not set (ie we are not being verbose). By convention, the string printed is of the form " NAME some args". Unfortunately to get nicely lined up output all the strings have to agree about what column the arguments should start in, which means that if we add a new quiet-command usage which wants a slightly longer CMD name then we either put up with misalignment or change every quiet-command string. Split the quiet-mode string into two, the "NAME" and the "same args" part, and use printf(1) to format the string automatically. This means we only need to change one place if we want to support a longer maximum name. In particular, we can now print 7-character names lined up properly (they are needed for the OSX "SETTOOL" invocation). Change all the uses of quiet-command to the new syntax. (Any which are missed or inadvertently reintroduced via later merges will result in slightly misformatted quiet output rather than disaster.) A few places in the pc-bios/ makefiles are updated to use "BUILD", "SIGN" and "STRIP" rather than "Building", "Signing" and "Stripping" for consistency and to keep them below 7 characters. Module .mo links now print "LD" rather than the nonstandard "LD -r".

2016-10-04qga/command: use QEMU atomic primitivesAlex Bennée1-8/+9
The guest client's use of the glib's g_atomic primitives causes newer GCC's to barf when built on Travis. As QEMU has its own primitives with well understood semantics we might as well use them. The use of atomics was a little inconsistent so I've also ensure the values are correctly set with atomic primitives at the same time. I also made the usage of bool consistent while I was at it.

2016-04-07qga: Workaround for console redirection from non-interactive qemu-ga serviceYuri Pudgorodskiy1-2/+2
mingw-glib uses helper process to assist gspawn() api. There are two versions of helpers, one with main() and another with WinMain() startup routines. Whenever gspawn() detects consoleless environment (and qemu-ga is running in such environment as Win32 service), it chooses helper with main() instead of WinMain. It is done by name, e.g. gspawn-win32-helper-console.exe vs gspawn-win32-helper.exe Running console-aware application like any win32 console apps from main() crt initalized process results in redirection of stdout to console created in crt startup instead of parent-provided handle connected to subprocess pipe. Thus, stdout/stderr redirection do not work correctly. The patch makes WinMain()'s version of helper be used as the only helper shipped with qemu-ga package. Using only win32 helper ensures console is created before any redirection and fixes stdout/stderr redirection issue. Signed-off-by: Yuri Pudgorodskiy <yur@virtuozzo.com> Signed-off-by: Denis V.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster1-0/+1
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-02-25qga: fix w32 breakage due to missing osdep.h includesMichael Roth5-9/+8
requester.h relied on qemu/compiler.h definitions to handle GCC_FMT_ATTR() stub, but this include was removed as part of scripted clean-ups via 30456d5: all: Clean up includes under the assumption that all C files would have included it via qemu/osdep.h at that point. requester.cpp was likely missed due to C++ files requiring manual/special handling as well as VSS build options needing to be enabled to trigger build failures. Fix this by including qemu/osdep.h. That in turn pulls in a macro from qapi/error.h that conflicts with a struct field name in requester.h, so fix that as well by renaming the field. While we're at it, fix up provider.cpp/install.cpp to include osdep.h as well.

Magic constants are a pain to use, especially when we run the risk that our choice of '1' for QGA_SEEK_CUR might differ from the host or guest's choice of SEEK_CUR. Better is to use an enum value, via a qapi alternate type for back-compatibility.

2015-11-25qga: Better mapping of SEEK_* in guest-file-seekEric Blake4-4/+46
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.

2015-11-17qga: fix for default env processing for guest-execYuri Pudgorodskiy1-1/+1
envp == NULL must be passed inside gspawn() if it was not passed with the command line. Original code inherits environment from the QGA, which is wrong.

2015-11-11qga: fix append file open modes for win32Kirk Allan1-14/+15
For append file open modes, use FILE_APPEND_DATA for the desired access for writing at the end of the file. Version 2: For "a+", "ab+", and "a+b" modes use FILE_APPEND_DATA|GENERIC_READ. ORing in GENERIC_READ starts a read at the begining of the file. All writes will append to the end fo the file. Added white space to maintain the alignment of the guest_file_open_modes[]. Signed-off-by: Kirk Allan <kallan@suse.com> Cc: qemu-stable@nongnu.org * use FILE_GENERIC_APPEND macro, which provides same semantics as FILE_APPEND_DATA, but retains other flags from GENERIC_WRITE Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
2015-11-04qga: set file descriptor in qmp_guest_file_open non-blocking on Win32Olga Krishtal1-0/+27
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. The usage of handles in qemu_set_non/block is impossible, because for win32 there is a difference between file discriptors and file handles, and all file ops are made via Win32 api.

2015-10-19qga: guest-exec simple stdin/stdout/stderr redirectionYuri Pudgorodskiy2-9/+187
Implemented with base64-encoded strings in qga json protocol. Glib portable GIOChannel is used for data I/O. Optinal stdin parameter of guest-exec command is now used as stdin content for spawned subprocess. If capture-output bool flag is specified, guest-exec redirects out/err file descriptiors internally to pipes and collects subprocess output. Guest-exe-status is modified to return this collected data to requestor in base64 encoding. Signed-off-by: Yuri Pudgorodskiy <yur@virtuozzo.com> Signed-off-by: Denis V.
