sstate: Add extra entries to the sstate duplicate files whitelist

2012-10-05T13:51:19+00:00

This avoids errors where gcc/binutils get installed to the native sysroot
in the same location for multiple package architectures. Ultimately making
these native recipes with ${PACKAGE_ARCH} appended to PN will resolve this
but hide the warnings until this gets sorted out.

Also hide the python and docbook catalog warnings since they're known about,
nothing to worry about and we'll aim to clean them up properly in the 1.4 cycle.

sstate: Normalise paths before comparing with the whitelist

2012-10-05T13:51:06+00:00

Without this, path components like // could break comparisions with the whitelist leading
to warnings being displayed to the user unintentionally.

sstate: Relax the duplicate file whitelist for now

2012-09-28T08:14:30+00:00

do_package is a machine specific task at the moment due to packagedata. This means
do_package tasks and their dependencies rerun between different machines
with various duplicate file installations. There are plans to fix this but they're
too invasive before release.

This patch relaxes the whitelist for sstate duplicate file detection to account
for this. Post-release, we re-enable stricter settings once do_package is not
machine specific.

sstate: Remove master manifest usage

2012-09-26T13:41:04+00:00

This was added to allow detection of duplicate files being installed by sstate.
There is a much simpler way, just check if the file already exists. This
effectively uses the kernel VFS as the cache which is much more efficient.

This resolves a significant performance bottleneck (lock contention on a
single file) when running builds that are just being generated from sstate
cache files.

sstate: Fix SSTATE_DUPWHITELIST variable usage

2012-09-26T13:40:46+00:00

We need to split this variable before using it. Otherwise a single "/"
character in the list whitelists every overlapping sysroot file which
was not the intention making the whole thing useless.

We'll start seeing warnings about overlapping files now this is working
correctly after this patch.

sstate: Append to EXTRASSTATEMAPS and add comment

2012-09-12T13:23:39+00:00

Appending to EXTRA_SSTATEMAPS is better than just hardcoding a value. Also
add a comment about why this is necessary.

sstate.bbclass: Remove hardcoded task mappings

2012-08-31T17:23:25+00:00

I've not idea why this got left in but as per the comment, it needs fixing
and we shouldn't have hardcoded mappings like this. Lets remove it
and dynamically generate the data instead.

sstate: Ensure master.list exists if it doesn't already

2012-08-31T05:44:52+00:00

This fixes builds where master.list doesn't already exist. This
change was meant to be part of the previous sstate commit but ended
up separated.

sstate.bbclass: Detect overwriting files in sstate controlled directories

2012-08-31T00:29:13+00:00

We have a potential problem where two sstate packages try and touch the same
file. This adds code which will print a warning whenever this happens.

The implementation does but by maintaining a master file list and comparing
file accesses against this. There are a number of places we have duplicate
accesses which are harmless, mostly in the deploy directory so these
are whitelisted.

For now the code prints warnings, this could be strengthened in future to
become error messages. Whilst working on this code on and off over the past
few months various issues were uncovered, some serious.
