these were already defined in stacks and were different here for no
apparent reason.

when using golang 1.17 build fail with errors like:

    github.com/jacobsa/fuse/internal/buffer.memclr: relocation target runtime.memclrNoHeapPointers not defined for ABI0 (but is defined for ABIInternal)

( grafana tag looks bizarre in git describe for some reason )

This contain the fix for go 1.16 that we backported, so we can use
upstream repository again

For now this still have to be enabled with a config like this in a .conf
file in srv/telegraf/extra-config/  :

    [[inputs.execd]]
      name_override = "slapos"
      # this needs sudo when using can not access supervisor socket, like when being installed in root slapos
      command = ["/usr/bin/sudo", "$SOFTWARE_DIR/go.work/bin/telegraf-input-slapos", "-config", "/path/to/slapos.conf"]

/path/to/slapos.conf would contain something like this:

    [[inputs.slapos]]
      ## Folder where partitions are located
      instance_root = "/srv/slapgrid/"

      ## filepath.Glob pattern to look for recursive instances
      recursive_instance_glob_pattern = "*/srv/runner/inst*/"

      ## Path of supervisor socket, relative to instance root
      socket_name = "sv.sock"

One notable change with this version has a new sql input, that can be
used to get metrics from sql queries.

This will force a password reset

Include the changes from 0b7511b4 (stack/erp5: expose random_activity_priority
argument of testrunner, 2021-11-22) to customized profiles from slapos
master

By setting this in the test suite configuration, we can force ERP5 tests
to use random priorities for activity processing.

The intended usage is to set this to an empty string, in which case
ERP5's runUnitTest chooses a random value for the seed and prints the
chosen value. It may also be possible to use a value, to reproduce a
previous run.

is not enough.

Anway, given how SST files are written, fallocate
is unlikely to be useful, even less on SSD.

RocksDB seems to have options to disable at runtime (see env/io_posix.cc)
but I see nothing for that in MariaDB configuration.

Steps to reproduce:

With a Btrfs partition (no specific mkfs option and for example 2GB size)
and following MariaDB configuration:

  [mysqld]
  datadir = /tmp/datadir
  disable-log-bin
  plugin-load = ha_rocksdb
  rocksdb_default_cf_options = compression=kNoCompression;bottommost_compression=kZSTD

execute the following queries with `mysql -uroot`:

> USE test;
> CREATE TABLE t(x MEDIUMBLOB) ENGINE=RocksDB;
> INSERT INTO t VALUES(repeat('.',16777215));
> INSERT INTO t SELECT x FROM t UNION ALL SELECT x FROM t;
> INSERT INTO t SELECT x FROM t UNION ALL SELECT x FROM t;
> INSERT INTO t SELECT x FROM t UNION ALL SELECT x FROM t;

Disk usage can be checked with:

> SHOW ENGINE RocksDB STATUS \G

  L0      1/0   144.00 MB ...
  L2      1/0   288.00 MB ...
 Sum      2/0   432.00 MB ...

and this can be compacted as follows:

> SET GLOBAL rocksdb_compact_cf='default';

> SHOW ENGINE RocksDB STATUS \G

  L2      1/0   16.28 KB  ...
 Sum      1/0   16.28 KB  ...

Now using `compsize` (on Debian, it's provided by btrfs-compsize package):

# with -DWITH_FALLOCATE=NO

Fixes 50f6a557 (component/trafficserver: build Lua plugin., 2021-11-23)
LuaJIT has to be build as shared to be referenced by trafficserver
component, because the later is already build as shared.
Also fix a missing rpath

Fixes dbd19730

The caucase binary have to be explicitly provided.

This fixes commit 79ccddeb

JSON schema uses simple string and internal process, and caddy instances are
not kept simple and are not considered future-proof.
