Whilst typically the URI query is a list of key-value pairs, that's not
actually required by the URI specification.
For example: http://example.com/foo?bar is a valid query, but this will
result in the fetcher raising an exception:
File "bitbake/lib/bb/fetch2/__init__.py", line 265, in __init__
self.query = self._param_str_split(urlp.query, "&")
File "bitbake/lib/bb/fetch2/__init__.py", line 293, in _param_str_split
for k, v in [x.split(kvdelim, 1) for x in string.split(elmdelim) if x]:
ValueError: not enough values to unpack (expected 2, got 1)
In this case the query is just "bar", but the fetcher is trying to split
it into a key-value pair.
The URI object exposes the parsed query explicitly as a dictionary of
key-value pairs, so we have to be a little creative here: if a value is
None then it isn't a key-value pair, but a bare key.
Fix this by handling elements without the deliminator in _param_str_split()
(by assigning the value to None), and handle a None value when formatting
the query in _param_str_join().

The current implementation only performs a git lfs fetch alongside of a
regular git fetch. This causes issues when the downloaded revision is
already part of the fetched repository (e.g. because of moving back in
history or the updated revision already being part of the repository at
the time of the initial clone).
Fix this by explicitly checking whether the required LFS objects are
available in the downloade directory before confirming that a downloaded
repository is up-to-date.
This issue previously went unnoticed as git lfs would silently fetch the
missing objects during the `unpack` task. With network isolation turned
on, this no longer works, and unpacking fails.

Some ditros don't enable /proc/pressure and it tends to be those which we
see bitbake timeout issues on, seemingly as load gets too high and the bitbake
processes don't get scheduled in for minutes at a time.
Add support for stopping running extra tasks if the system load average goes
above a certain threshold by setting BB_LOADFACTOR_MAX.
The value used is scaled by CPU number, so a value of 1 would be when
the load average equals the number of cpu cores of the system, under one
only starts tasks when the load average is below the number of cores.
This means you can centrally set a value such as 1.5 which will then
scale correctly to different sized machines with differing numbers
of CPUs.
The pressure regulation is probably more accurate and responsive, however
our graphs do show singificant load spikes on some workers and this
patch is aimed at trying to avoid those.
Pressure regulation is used where available in preference to this load
factor regulation when both are set.

For gitsm recipes, it's possible that some URL is used more than once.
e.g.,
A -> B:rev1 (B is a submodule of A)
A -> C (C is a submodule of A)
C -> B:rev2 (B is a submodule of C)
A anc C are both using B as submodules, but on different revs.
Now if we have:
B:rev1 -> D
B:rev2 -> E
Then, the mirror will not be fully used.
Say we have all repo mirrors for A, B, C, D, E, then in theory it's not
necessary to reach out to any network for downloading. But it's not the
case. After downloading B(rev1) and its submodule D from mirrors, the fetch
process continues to download C, thus B(rev2) and E. Now it finds that B
needs an update because its submodule E needs an update. Of course this is
true because E is not downloaded yet. Now the problem comes to whether to
use mirror or not. The git.py defines try_premirror to return 'False' when
the ud.clonedir exists. As B has been cloned, the ud.clonedir exists and
try_mirror returns False, resulting in not using mirror and going to upstream
directly.
We can see that the mirrors are not fully used. This is usually not problem,
as the cost is only some network download. But in case the following two
settings are there, we get errors.
BB_NO_NETWORK = "0"
BB_ALLOWED_NETWORKS = "*.some.allowed.domain"
In such case, the gitsm recipe A will fail to fetch. Note that all contents
that A needs are in mirrors and now it's failing to fetch. This is unexpected.
Note that the different revs of the same repo in gitsm recipe is not the only
way to reveal this problem. For example, there might be a recipe call B that
uses B:rev3. Check the protobuf and grpc recipes as an example.
For now, we can use the following steps to reproduce this issue. To be clear,
the grpc recipe in meta-oe is now 1.60.0.
1. Add in local.conf:
DL_DIR = "${TOPDIR}/downloads-premirror"
bitbake grpc -c fetch
2. Comment out the DL_DIR setting in local.conf and add the following lines:
PREMIRRORS:append = " \
git://.*/.* git://${TOPDIR}/downloads-premirror/git2/MIRRORNAME;protocol=file \n \
gitsm://.*/.* gitsm://${TOPDIR}/downloads-premirror/git2/MIRRORNAME;protocol=file \n \
"
3. Set BB_NO_NETWORK = "1" and then 'bitbake grpc -c fetch'.
This command succeeds and this shows that the premirror holds everything we need.
4. Add the following lines and then 'bitbake grpc -c fetch'.
BB_NO_NETWORK = "0"
BB_ALLOWED_NETWORKS = "*.some.domain"
After step 4, the error message is as below:
ERROR: grpc-1.60.0-r0 do_fetch: The URL: 'gitsm://github.com/protocolbuffers/protobuf.git;protocol=https;name=third_party/protobuf;subpath=third_party/protobuf;nobranch=1;lfs=True;bareclone=1;nobranch=1' is not trusted and cannot be used
This patch fixes this problem by handling this corner case, that is, if the URL is
not trusted from the settings of BB_NO_NETWORK and BB_ALLOWED_NETWORKS, then we should
try premirrors because trying to reach upstream is destined to fail.

To avoid this, mark when it has been done and don't reprocess until dependencies
are updated. We have to be careful as we've seen bugs where these dependencies
aren't processed at the right time. They also have to be reproceseed during task
