See patch commit messages for rationale
Ideally we would convert other callers of qemu_open to use
qemu_open_err, and eventually remove qemu_open, renaming
qemu_open_err back to qemu_open. Given soft freeze is just
days away though, I'm hoping this series is simple enough
to get into this release, leaving bigger cleanup for later.
Improved in v5:
- Drop reporting of flags in failed open call
- Split O_CLOEXEC handling off into separate helper
- Refactor monitor FD set APIs to simplify their use
Improved in v4:
- Use assert() for programmer mistakes
- Split second patch into three distinct parts
- Misc typos
- Improve commit message
Improved in v3:
- Re-arrange the patches series, so that the conversion to Error
takes place first, then the improve O_DIRECT reporting
- Rename existing method to qemu_open_old
- Use a pair of new methods qemu_open + qemu_create to improve
arg checking
Improved in v2:
- Mention that qemu_open_err is preferred over qemu_open
- Get rid of obsolete error_report call
- Simplify O_DIRECT handling
- Fixup iotests for changed error message text
Daniel P. Berrangé (8):
monitor: simplify functions for getting a dup'd fdset entry
util: split off a helper for dealing with O_CLOEXEC flag
util: rename qemu_open() to qemu_open_old()
util: refactor qemu_open_old to split off variadic args handling
util: add Error object for qemu_open_internal error reporting
util: introduce qemu_open and qemu_create with error reporting
util: give a specific error message when O_DIRECT doesn't work
block/file: switch to use qemu_open/qemu_create for improved errors
