The current default value for BB_PRESSURE_MAX_CPU is 500, which is
really low for most systems. Provide a value of 15000 which limits the
load average without being extremely slow either.
Provide similar values for BB_PRESSURE_MAX_IO and
BB_PRESSURE_MAX_MEMORY. Mention that these should be adjusted depending
on the need, and warn about the potential spam of messages when the
value is too low.

When reviewing proposed fragments to add settings for DISTRO and MACHINE,
RP noted that such fragments only add clutter and overhead, and there's
no need to maintain them as separate files.
Rather when bitbake sees 'fragmentvar/fragmentvalue' it can expand that into
FRAGMENTVAR = "fragmentvalue".
To achieve that, 'addfragments' directive is extended with a parameter
that sets the name of the variable that holds definitions of such
built-in fragments, for example like this:
"machine:MACHINE distro:DISTRO"
Then each enabled fragment name is matched against these definitions and the
respective variable is set, e.g. 'machine/qemuarm' would match
'machine:MACHINE' and result in MACHINE set to 'qemuarm'.
This happens before any fragment files are looked up on disk,
and no such lookup happens if there was a match, which should prevent
possible misuse of the feature. So the builtin fragment definition
is also an allowlist for them.
Please also see the patches for oe-core that show an application of the feature.

DANGLINGAPPENDS_WARNONLY is a very poorly designed interface and
is commonly abused. The challenge is that once it is set, by any
layer, it applies everywhere.
Some layers rely on this to get notification they need to update
bbappend files and having the behaviour change from inclusion of an
antisocial layer is not good.
In addition, showing warnings as an accepted thing on the console
devalues them and trains the user to ignore them. I want to steer us
away from this mindset.
We could extend the functionality and make it apply only to certain
layers, or only to certain appends but then we've basically re-invented
BBMASK.
Given all the above, we should drop support for BB_DANGLINGAPPENDS_WARNONLY
and direct anyone with issues to BBMASK instead.

This fetcher allows BitBake to fetch from a Google Cloud Storage
bucket. The fetcher expects a gs:// URI of the following form:
SSTATE_MIRRORS = "file://.* gs://<bucket name>/PATH"
The fetcher uses the Google Cloud Storage Python Client, and
expects it to be installed, configured, and authenticated prior
to use.
If accepted, this patch should merge in with the corresponding oe-core
patch titled "Add GCP fetcher to list of supported protocols".
Some comments on the patch:
There is also documentation for the fetcher added to the User
Manual. I'm still not completely sure about the recommends_checksum()
being set to True. As I've noted in the mailing list, it will throw
warnings if the fetcher is used in recipes without specifying a
checksum. Please let me know if this is intended behavior or if it
should be modified.
Here is how this fetcher conforms to the fetcher expectations
described at this link:
https://git.yoctoproject.org/poky/tree/bitbake/lib/bb/fetch2/README
a) Yes, network fetching only happens in the fetcher
b) The fetcher has nothing to do with the unpack phase so there is no
network access there
c) This change doesn't affect the behavior of DL_DIR. The GCP fetcher
only downloads to the DL_DIR in the same way that other fetchers,
namely the S3 and Azure fetchers do.
d) The fetcher is identical to the S3 and Azure fetchers in this
context
e) Yes, the fetcher output is deterministic because it is downloading
tarballs from a bucket and not modifying them in any way.
f) I set up a local proxy using tinyproxy and set the http_proxy
variable to test whether the Python API respected the proxy. It
appears that it did as I could see traffic passing through the
proxy. I also did some searching online and found posts indicating
that the Google Cloud Python APIs supported the classic Linux proxy
variables, namely:
- https://github.com/googleapis/google-api-python-client/issues/1260
g) Access is minimal, only checking if the file exists and downloading
it if it does.
h) Not applicable, BitBake already knows which version it wants and
the version infomation is encoded in the filename. The fetcher has no
concept of versions.
i) Not applicable
j) Not applicable
k) No tests were added as part of this change. I didn't see any tests
for the S3 or Azure changes either, is that OK?
l) I'm not 100% familiar but I don't believe this fetcher is using any
tools during parse time. Please correct me if I'm wrong.
