b643d2bc17 bitbake: siggen: Fix inefficient string concatenation
As discussed in https://stackoverflow.com/a/4435752/1710392 , CPython
has an optimization for statements in the form "a = a + b" or "a += b".
It seems that this line does not get optimized, because it has a form a = a + b + c:
data = data + "./" + f.split("/./")[1]

For that reason, it does a copy of data for each iteration, potentially copying megabytes
of data for each iteration.

Changing this line causes SignatureGeneratorBasic::get_taskhash to take 0.06 seconds
instead of 45 seconds on my test setup where SRC_URI points to a big directory.

Note that PEP8 recommends explicitely not to use this optimization which is specific to CPython:
"do not rely on CPython’s efficient implementation of in-place string concatenation for statements in the form a += b or a = a + b"

However, the PEP8 recommended form using "join()" also does not avoid the copy and takes 45 seconds in my test setup:
data = ''.join((data, "./", f.split("/./")[1]))

I have changed the other lines to also use += for consistency only, however those were in the form a = a + b
and were optimized already.

f97a46b07f bitbake: fetch2/git: Prevent git fetcher from fetching gitlab repository metadata
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.

251869992f bitbake: bb/utils: include SSL certificate paths in export_proxies
bb.utils.export_proxies() is a poor-man's alternative for the
environment setup code in bb/fetch2, but it's used in several places
where recipes want to download manually (such as cve-update-db-native).

Notably, export_proxies() doesn't pass on the SSL certificate paths from
the original environment, so if SSL_CERT_FILE needs to be set (for
example, in a buildtools environment) then proxies work but SSL doesn't.

In an ideal world export_proxies and the same logic in fetch2 would
merge, but until then we can add the SSL_CERT_ variables and duplicate
the basic logic: check the datastore first and then the original
environment for variables.

Also remove the return value as nothing ever checked it.

Commit 0361ecf7eb82c386a9842cf1f3cb706c0a112e77 introduced regression
in submodules path parsing. As the result gitsm fetcher fails on each
submodule which name begins from the name of the parent repo which is
totally valid usecase [Yocto #14045] [1]
Fix the code to error out only if submodule's name is equal to parent
name but not if it's part of it.

6282ef6c7c bitbake: runqueue: Fix race issues around hash equivalence and sstate reuse
We identified a use case where a native recipe (autoconf-native) was
rebuilt with no change in output yet the sstate for do_package tasks
wasn't being used.

The issue is that do_package tasks have a hard dependency on
pseudo-native:do_populate_sysroot. That task was one of the many
tasks being rehashed when autoconf-native's hash was changed.

If update_tasks processed a recipe before it had processed pseudo-native,
that recipe would be marked as not possible from sstate and would
run the full tasks.

The fix is to split the processing into two passes, first to handle
the existing covered/notcovered updates, then in the second pass,
check whether there are "harddep" issues.

This defers the do_package tasks until after pseudo-native is installed
from sstate as expected and everything works well again.

67e4012e62 bitbake: asyncrpc/client: Fix unix domain socket chdir race issues
The connect_unix() call had a bug where if a relative path to a socket
was passed (which the non-async client always does), and the current
working directory was changed after the initial call, it would fail to
reconnect if it became disconnected, since the socket couldn't be found
relative to the new current working directory.

To work around this, change the socket connection for UNIX domain
sockets to be synchronous and change current working before connecting.
This isn't ideal since the connection could block the entire event loop,
but in practice this shouldn't happen since the socket are local files
anyway.

Help debugging and resolving from Joshua Watt.

4b9ac6d5aa bitbake: Fix npm to use https rather than http
Hit this error while building nlf-native recently:
{
  "error": {
    "summary": "URI malformed",
    "detail": ""
  }
}

Some poking about led me to discover that:
1) The npm.py tool replaces npm:// with http://, not https://
2) Some versions of the npm tool don't handle 301 redirects properly,
   choosing to display the above error instead when using the default
   nodejs registry

It would be good to go fix npm to handle the redirect properly, but it
seems like it would also be good to assume secure http when contacting a
registry, hence, this patch

ace871c199 bitbake: siggen: Fix insufficent entropy in sigtask file names
Signature generation uses mkstemp() to get a file descriptor to a unique
file and then write the signature into it. However, the unique file name
generation in glibc is based on the system timestamp, which means that
with highly parallel builds it is more likely than one might expect
expected that a conflict will occur between two different builder nodes.
When operating over NFS (such as a shared sstate cache), this can cause
race conditions and rare failures (particularly with NFS servers that
may not correctly implement O_EXCL).

The signature generation code is particularly susceptible to races since
a single "sigtask." prefix used for all signatures from all tasks, which
makes collision even more likely.

To work around this, add an internal implementation of mkstemp() that
adds additional truly random entropy to the file name to eliminate
conflicts.

c4745d9c7d bitbake: runqueue: Drop deadlock breaking force fail
I'm 99% certain this failing of a scenequeue task corrupts runqueue and
causes all kinds of breakage. I'd rather runqueue deadlocked than corrupted
and did weird things so drop this code.

We've seen builds where the deadlock triggers and it then tries to run tasks
where the SQ task already ran with very confusing failures. It is likely it
is this code causing it.

Pass additional arguments in the fileslocked() context manager to the
underlying lockfile() function. This allows the context manager to be
used for any types of locks (non-blocking, shared, etc.) that the
lockfile() function supports.

2e193726bd bitbake: bitbake: runqueue: add memory pressure regulation
Prevent new tasks from being scheduled if the memory pressure is above
a certain threshold, specified through the "BB_MAX_PRESSURE_MEMORY"
variable in the conf/local.conf file. This is an extension to the
following commit and hence regulates pressure in the same way:
   48a6d84de1 bitbake: runqueue: add cpu/io pressure regulation

Memory pressure is experienced when time is spent swapping, refaulting
pages from the page cache or performing direct reclaim. This is why
memory pressure is rarely seen but might be useful as a last resort to
prevent OOM errors.

3b18438166 bitbake: bitbake: runqueue: add cpu/io pressure regulation
Prevent the scheduler from starting new tasks if the current cpu or io
pressure is above a certain threshold and there is at least one active
task. This threshold can be specified through the
"BB_PRESSURE_MAX_{CPU|IO}" variables in conf/local.conf.

The threshold represents the difference in "total" pressure from the
previous second. The pressure data is discussed in this oe-core commit:
   061931520b buildstats.py: enable collection of /proc/pressure data
where one can see that the average and "total" values are available.
From tests, it was seen that while using the averaged data was somewhat
useful, the latency in regulating builds was too high. By taking the
difference between the current pressure and the pressure seen in the
previous second, better regulation occurs. Using a shorter time period
is appealing but due to fluctations in pressure, comparing the current
pressure to 1 second ago achieves a reasonable compromise. One can look
at the buildstats logs, that usually sample once per second, to decide a
sensible threshold.

If the thresholds aren't specified, pressure is not monitored and hence
there is no impact on build times. Arbitary lower limit of 1.0 results
in a fatal error to avoid extremely long builds. If the limits are higher
than 1,000,000, then warnings are issued to inform users that the specified
limit is very high and unlikely to result in any regulation.

The current bitbake scheduling algorithm requires that at least one
task be active. This means that if high pressure is seen, then new tasks
will not be started and pressure will be checked only for as long as at
least one task is active. When there are no active tasks, an additional task
will be started and pressure checking resumed. This behaviour means that
if an external source is causing the pressure to exceed the threshold,
bitbake will continue to make some progress towards the requested target.
This violates the intent of limiting pressure but, given the current
scheduling algorithm as described above, there seems to be no other option.
In the case where only one bitbake build is running, the implications of
the scheduler requirement will likely result in pressure being higher
than the threshold. More work would be required to ensure that
the pressure threshold is never exceeded, for example by adding pressure
monitoring to make and ninja.

759a3eb9b5 bitbake: server/process: Fix logging issues where only the first message was displayed
I realised only the first logging message was being displayed in a given
parsing process. The reason turned out to be the UI handler failing
with a "pop from empty list". The default handler was then lost and
no further messages were processed.

Fix this by catching the exception correctly in the connection writer code.

03cc5f63bc bitbake: build: Add clean_stamp API function to allow removal of task stamps
We currently have no API to be able to remove all the potential stamps of a
task. It is unusual to need to do this, particularly as you could race against
other things happening in the system but we do have a use case for this in
cleaning up sysroots in OE-Core. The alternative is to mess with CLEANMASK in
OE-Core but that is just going to add potential for errors.

We need the first part of the make_stamp() function so separate that out so
it can be called seperately.

The current fetcher seemed to have some issues that made it difficult when
trying to use the same. This patch fixes the following

* Make consistent use of the path that needs to be used as oscdir
* The path mentioned in os.access in download function was not same as
  ud.moddir which would result into invoking of fetch command instead of
  update command even if directory already existed
* Before creating oscrc, make sure oscdir exists and create it if it does
  not exist
* Updated the configuration to use apiurl and added a new parameter to
  control whether http or https needs to be used to connect to apiurl
