2012-06-04qemu-option: qemu_opts_from_qdict(): use error_set()Luiz Capitulino
do_device_add() and do_netdev_add() call qerror_report_err() to maintain their QError semantics. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-By: Laszlo Ersek <lersek@redhat.com>
2012-06-04qemu-option: introduce qemu_opt_set_err()Luiz Capitulino
This is like qemu_opt_set(), except that it takes an Error argument. This new function allows for a incremental conversion of code using qemu_opt_set(). Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-By: Laszlo Ersek <lersek@redhat.com>
2012-06-04qemu-option: qemu_opts_validate(): use error_set()Luiz Capitulino
net_client_init() propagates the error up by calling qerror_report_err(), because its users expect QError semantics. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-By: Laszlo Ersek <lersek@redhat.com>
2012-06-04qemu-option: qemu_opts_create(): use error_set()Luiz Capitulino
This commit converts qemu_opts_create() from qerror_report() to error_set(). Currently, most calls to qemu_opts_create() can't fail, so most callers don't need any changes. The two cases where code checks for qemu_opts_create() erros are: 1. Initialization code in vl.c. All of them print their own error messages directly to stderr, no need to pass the Error object 2. The functions opts_parse(), qemu_opts_from_qdict() and qemu_chr_parse_compat() make use of the error information and they can be called from HMP or QMP. In this case, to allow for incremental conversion, we propagate the error up using qerror_report_err(), which keeps the QError semantics Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-By: Laszlo Ersek <lersek@redhat.com>
2012-02-17qemu-option: Add support for merged QemuOptsListsPeter Maydell
Add support for option lists which are merged together, so that "-listname foo=bar -listname bar=baz" is equivalent to "-listname foo=bar,bar=baz" rather than generating two separate lists of options.

2012-02-01qemu-option: Introduce default mechanismJan Kiszka
This adds qemu_opts_set_defaults, an interface provide default values for a QemuOpts set. Default options are parsed from a string and then prepended to the list of existing options, or they serve as the sole QemuOpts set.

2010-05-28add support for protocol driver create_optionsMORITA Kazutaka
This patch enables protocol drivers to use their create options which are not supported by the format. For example, protcol drivers can use a backing_file option with raw format. Signed-off-by: MORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-03-16qemu-option: Move the implied first name into QemuOptsListMarkus Armbruster
We sometimes permit omitting the first option name, for example -device foo is short for -device driver=foo. The name to use ("driver" in the example) is passed as argument to qemu_opts_parse(). For each QemuOptsList, we use at most one such name. Move the name into QemuOptsList, and pass whether to permit the abbreviation. This ensures continued consistency, and simplifies the commit after next in this series.

The functions are somewhat restricted. Good enough for the job at hand. We'll extend them when we need more.

2009-10-06Add qemu_opts_validate() for post parsing validationMark McLoughlin
Several qemu command line options have a parameter whose value affects what other parameters are accepted for the option. In these cases, we can have an empty description table in the QemuOptsList and once the option has been parsed we can use a suitable description table to validate the other parameters based on the value of that parameter.

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

looking for id= and creating a new QemuOpts instance is splitted from the actual option parser code now, so the parser can be called from other contexts too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-27QemuOpts: framework for storing and parsing options.Gerd Hoffmann
This stores device parameters in a better way than unparsed strings. New types: QemuOpt - one key-value pair. QemuOpts - group of key-value pairs, belonging to one device, i.e. one drive. QemuOptsList - list of some kind of devices, i.e. all drives. Functions are provided to work with these types. The plan is that some day we will pass around QemuOpts pointers instead of strings filled with "key1=value1,key2=value2". Check out the next patch to see all this in action ;) Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-05-22Create qemu-option.hKevin Wolf
This patch creates a new header file and the corresponding implementation file for parsing of parameter strings for options (like used in -drive). Part of this is code moved from vl.c (so qemu-img can use it later). The idea is to have a data structure describing all accepted parameters. When parsing a parameter string, the structure is copied and filled with the parameter values. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
