Hi,
[bitbake 1.12 / OE 2010.12]
I am facing a quite strange issue with packaged-staging (INHERIT +=
"packaged-staging" in local.conf) when trying to use a pre-built toolchain.
1. First I build the toolchain:
$ bitbake meta-toolchain
2. Then I save out the ${PSTAGE_DIR} somewhere and remove ${TMPDIR}:
$ rsync -a --delete ${PSTAGE_DIR} /path/to/pstage_mirror
$ rm -rf ${TMPDIR}
3. Now I restore only the staging dir, and build something:
$ mkdir -p ${PSTAGE_DIR}
$ rsync -a /path/to/pstage_mirror ${PSTAGE_DIR}
$ time bitbake busybox
=> works fine: packaged staging is working as expected, the toolchain is not
rebuilt and busybox is built in few minutes.
4. Now, rather than manually restoring the ${PSTAGE_DIR}, I want to use
PSTAGE_MIRROR. The point is, if the URI for PSTAGE_MIRROR is anything but
file://, it works fine, e.g.:
## put PSTAGE_MIRROR = http://localhost:pstage_mirror in local.conf, and
## configure the web server to make this uri points to /path/to/pstage_mirror
$ rm -rf ${TMPDIR}
$ time bitbake busybox
=> it works fine.
But if I set PSTAGE_MIRROR = "file:///path/to/pstage_mirror"
=> does not work, the prebuilt packages are not used and everything gets
re-compiled.
I looked inside the class packaged-staging.bbclass, to try to figure out the
problem.
The pre-built package is fetched during do_setscene. In the function
packagestage_scenefunc(), there is following code:
stagepkg = bb.data.expand("${PSTAGE_PKG}", d)
if not os.path.exists(stagepkg):
staging_fetch(stagepkg, d)
if os.path.exists(stagepkg):
...
stagepkg points to the ipk file in ${PSTAGE_DIR} (which is not yet present).
The problem is, after returning from staging_fetch(), the file is still not
present:
# Try a fetch from the pstage mirror, if it fails just return and
# we will build the package
bb.debug(1, "Attempting to fetch staging package %s" % (bn))
try:
bb.fetch.init([srcuri], pd)
bb.fetch.go(pd, [srcuri])
except Exception, ex:
bb.debug(1, "Failed to fetch staging package %s: %s" % (bn, ex))
else:
bb.debug(1, "Fetched staging package %s" % bn)
=> bb.fetch.go() does not throw an exception, _but_ the file has not been
fetched.
I guess this must already have worked, mainly because of this comment in the
.bbclass:
# To use the prebuilt pstage packages, save them away..
# $ rsync --delete -a tmp/pstage/ /there/oe/build/pstage_mirror
# .. and use it as mirror in your conf/local.conf:
# PSTAGE_MIRROR = "file:///there/oe/build/pstage_mirror"
So I wondered if someone can confirm that PSTAGE_MIRROR has already worked with
a file:/// uri,
and could see what I am missing here.
With Kind regards,
Fabrice
