Re: [Bug-ddrescue] [PATCH] Add proper device size and name detection on Haiku

[Felix Ehlermann]

Dear Antonio,

wouldn't it be possible to implement some kind of plug-in support in
ddrescue?

This way other people (like Francois) could possibly contribute their
(platform specific) features by providing plugins. The plugins would of
course be platform specific - but ddrescue remains POSIX compliant while at
the same time it would gain a lot of additional features on certain
platforms.

One example would be the start of a recovery:
If there was some kind of event, callback, hook, etc. that is raised/called
before the device is being accessed, a plugin could for example send some
device specific commands to disable bad sector relocation before ddrescue
continues with its usual operation.
(IIRC the discussion about this some while ago on the list this was not
possible using POSIX compliant code, but if it was platform specific code it
would be possible to implement.)


Kind Regards
Felix Ehlermann

Thank you for the patch, but I'm afraid it does not fit in the ddrescue 
philosophy.

Ddrescue needs a proper POSIX system to work. The 'linux.h' non-portable 
extensions are there to provide functionality beyond what POSIX 
provides, not to work around limitations in POSIX implementations.


Regards,
Antonio.
