This is inspired by the same section in the yocto-docs. It aims to provide
information in what contexts(recipes, .conf, bbclass,...) a variable is usually
used. For that I tried to group similar variables, so that a short overview is
given. This was inspired by [YOCTO #14072], but of course does not implement a
warning if a variable is used in an unintended context.

This variable is implemented in OE-Core, and therefore

Using tags with the git fetcher may cause surprising behaviour. There
are reasons for this, document them.

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.

The application order of override syntax :append, :prepend, :remove is
inobvious and undocumented. The order does not match variable parse
history, i.e. output of "bitbake -e", either.
Add note documenting the exact order in which :append, :prepend, :remove
are applied to variable in lib/bb/data_smart.py getVarFlag(). Add note
that this order does not match the variable parse history order. This
is mostly to prevent others from running into this and scratching their
heads, trying to find out what is going on.

The bitbake git fetcher currently fetches 'refs/*:refs/*', i.e. every
single object in the remote repository. This works poorly with gitlab
and github, which use the remote git repository to track its metadata
like merge requests, CI pipelines and such.
Specifically, gitlab generates refs/merge-requests/*, refs/pipelines/*
and refs/keep-around/* and they all contain massive amount of data that
are useless for the bitbake build purposes. The amount of useless data
can in fact be so massive (e.g. with FDO mesa.git repository) that some
proxies may outright terminate the 'git fetch' connection, and make it
appear as if bitbake got stuck on 'git fetch' with no output.
To avoid fetching all these useless metadata, tweak the git fetcher such
that it only fetches refs/heads/* and refs/tags/* . Avoid using negative
refspecs as those are only available in new git versions.
Per feedback on the ML, Gerrit may push commits outsides of branches or
tags during CI runs, which currently works with the 'nobranch=1' fetcher
parameter. To retain this functionality, keep fetching everything in case
the 'nobranch=1' is present. This still avoids fetching massive amount of
data in the common case, since 'nobranch=1' is rare. Update 'nobranch'
documentation.

Inform the reader that there should be no need for spaces in the value
when using removal override `:remove`.
Considering why spaces are used in the other override operators, it
might seem obvious that they aren't needed for the removal operator.
But, it seems like I'm not the first to be confused about this.
