Summary: fetcher allows to run more conflicting parallel fetches
Product: BitBake
Version: 1.8.x
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: BitBake
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
Running "bitbake -v angstrom-x11-image" on 8 processor Xeon machine, I enabled
parallel build by:
PARALLEL_MAKE="-j16"
BB_NUMBER_THREADS = "16"
It caused a lot of fetch errors, expecially for gcc-4.1.2.tar.bz2 and
glibc-2.5.tar.bz2.
I did not analyze the problem in deep, but it seems, that these files are used
as source in more packages and bitbake runs fetch of the same file more times
on different processors.
It causes file corruption and visible appearing "+" in wget logs saying that
wget uses append mode.
As a work around it it is possible to run initial fetch of build process in
less number of processors and then increase its number.
