2014-03-13qemu-io: Fix warnings from static code analysisStefan Weil1-1/+1
Smatch complains about several global symbols which should be local. Add the missing 'static' attributes and move the 'extern' declaration of variable qemuio_misalign to qemu-io.h. This variable also changes the type from 'int' to 'bool' which better fits documents its use.

2014-01-24qemu-io: New command 'sleep'Kevin Wolf1-0/+42
There is no easy way to check that a request correctly waits for a different request. With a sleep command we can at least approximate it. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2014-01-22qemu-io: add command completionStefan Hajnoczi1-0/+15
Autocomplete qemu-io commands at the interactive prompt. Note this only completes command names and not their options. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-11-29blkdebug: add "remove_break" commandFam Zheng1-0/+22
This adds "remove_break" command which is the reverse of blkdebug command "break": it removes all breakpoints with given tag and resumes all the requests. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2013-10-11block/qapi: Human-readable ImageInfoSpecific dumpMax Reitz1-0/+9
Add a function for generically dumping the ImageInfoSpecific information in a human-readable format to block/qapi.c. Use this function in bdrv_image_info_dump and qemu-io-cmds.c:info_f to allow qemu-img info resp. qemu-io -c info to print that format specific information.

2013-09-06block: expect errors from bdrv_co_is_allocatedPaolo Bonzini1-0/+4
Some bdrv_is_allocated callers do not expect errors, but the fallback in qcow2.c might make other callers trip on assertion failures or infinite loops. Fix the callers to always look for errors.

2013-08-22aio / timers: Untangle include filesAlex Bligh1-0/+1
include/qemu/timer.h has no need to include main-loop.h and doing so causes an issue for the next patch. Unfortunately various files assume including timers.h will pull in main-loop.h. Untangle this mess. Signed-off-by: Alex Bligh <alex@alex.org.uk> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2013-06-06qemu-io: Move 'help' functionKevin Wolf1-1/+66
No reason to treat it different from other commands. Move it to qemu-io-cmds.c, adapt the coding style and register it like any other command. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-06-06qemu-io: Factor out qemuio_commandKevin Wolf1-0/+24
It's duplicated code. Move it to qemu-io-cmds.c because it's not dependent on any static data of the qemu-io tool. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-06-06qemu-io: Split off commands to qemu-io-cmds.cKevin Wolf1-0/+1835
This is the implementation of all qemu-io commands that make sense to be called from the qemu monitor, i.e. everything except open, close and quit. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
