simplest use of SSTATE_MIRRORS?

simplest use of SSTATE_MIRRORS?

[Robert P. J. Day]

  colleague asked me how SSTATE_MIRRORS worked, so i had to check,
followed the section here:

http://docs.yoctoproject.org/overview-manual/concepts.html#shared-state-cache

and in one of own builds, i moved the entire sstate-cache directory
to ~/SSTATE as is, then added the following to my site.conf:

SSTATE_MIRRORS = " \
        file://.\* file:///home/rpjday/SSTATE/PATH \
"

  then i removed all of /tmp in my current build, and re-ran my
bitbake command, but it seems to be doing all the standard fetching
and unpacking and so on. what clearly trivial step have i overlooked?

p.s. i checked with "bitbake -e" that that variable seems to have the
correct value. what silliness have i done?

The example in local.conf.sample uses file://.* rather than file://.\*

   i noticed that a bit later, made the change and all good. so i guess
i'll submit a patch for the manual.

The other gotcha with this now is hash equivalence. If that is active, you need
both the sstate data and hash equivalence data that match.

  i did notice that in the sstate section in the manual, and was
digging into it as we speak.
