Historically, user monitor arguments beginning with '-' (eg. '-f') were passed as integers down to handlers. I've maintained this behavior in the new monitor because we didn't have a boolean type at the very beginning of QMP. Today we have it and this behavior is causing trouble to QMP's argument checker. This commit fixes the problem by doing the following changes: 1. User Monitor Before: the optional arg was represented as a QInt, we'd pass 1 down to handlers if the user specified the argument or 0 otherwise This commit: the optional arg is represented as a QBool, we pass true down to handlers if the user specified the argument, otherwise _nothing_ is passed 2. QMP Before: the client was required to pass the arg as QBool, but we'd convert it to QInt internally. If the argument wasn't passed, we'd pass 0 down This commit: still require a QBool, but doesn't do any conversion and doesn't pass any default value 3. Convert existing handlers (do_eject()/do_migrate()) to the new way Before: Both handlers would expect a QInt value, either 0 or 1 This commit: Change the handlers to accept a QBool, they handle the following cases: A) true is passed: the option is enabled B) false is passed: the option is disabled C) nothing is passed: option not specified, use default behavior Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> --- blockdev.c | 2 +- migration.c | 16 +++++++--------- monitor.c | 17 +++-------------- 3 files changed, 11 insertions(+), 24 deletions(-)
