XCP: source repo?

XCP: source repo?

[YAMAMOTO Takashi]

hi,

is there publically available source code repository
which contains files under xcp's /opt?
i looked at the following repos but no luck.

	xen-api.hg
	xen-api-libs.hg
	xen-dist-ocaml.hg
	xen-3.4-testing.hg
	xen-unstable.hg

i'm particularly interested in /opt/xensource/sm/*.

thanks.

/opt/xensource/sm/* contains python scripts which are not compiled.

Hi,

One of the next items on my to-do list is to create a new repo "xen-sm.hg" which will contain everything in /opt/xensource/sm/* I'll try to do that over the next few weeks.

As David says, the sources are all present and the files should all have proper license info (LGPL). Feel free to send patches via xen-api@lists.

Cheers,
Dave

is /opt/xensource/sm/* a correct place to look at?

Yes.I think it is the correct place to place your sm driver in.
Make sure your driver name endswith SR.

I think the source code is the best we've got atm. I recommend looking at one of the simpler SRs first e.g.
 DummySR: this is a "pretend" SR, used for testing
 udevSR: represents block devices hotplugged into the host ('xe vdi-introduce' 'xe vdi-forget' are called from udev scripts)
and then maybe extSR: vhds on local storage.

Cheers,
Dave

having take a quick look at DummySR, i have a question.

    if __name__ == '__main__':
        SRCommand.run(DummySR, DRIVER_INFO)
    else:
        SR.registerSR(DummySR)

i understand that the SRCommnad.run part is for XMLRPC with
sm_type Executable.  what is the SR.registerSR part for?
i couldn't find any python code which imports this file.

I don't believe the registerSR bit is currently used - you can safely ignore this.
