In Ubuntu autopkgtest infra we need to whitelist the addresses which
will receive requests to not be proxied, and 'puppet' is used in the
test.

It fixes an autopkgtest regression in ruby-puppet-syntax.

This makes lintian happy and additionally the package will behave in the
same way under sysvinit and systemd.

dh_installinit features a --no-enable flag that basically passes
defaults-disabled to update-rc.d. Use that instead, as it's cleaner than
passing defaults-disabled explicitly.

It contains a single item, referring to a dead link.

The puppetmaster, puppetmaster-passenger and puppet-common packages
have been transitional since Stretch, it's time to remove them.

Closes: #940760, #940761, #940762

There are some stray `require 'sync'` statements left over from the 2.7
days. 'sync' is an external gem in Ruby 2.7; rather than add a
dependency against ruby-syncm, cherry-pick upstream commit
a53cb826b56b1531e7b0c1cd82d72f2f41ae6b09 that removes the 'require'
statements altogether.

 - B-D on debhelper-compat (= 12)
 - d/rules: use dh_missing instead of dh_install --fail-missing
 - Add Pre-Depends: ${misc:Prepends} for dh_systemd

(PUP-10309) Reduce UTF-8 acceptance risk

This commit reduces the audit risk level of UTF-8 acceptance tests from
"audit:high" to "audit:medium" where the risk level is no longer
considered high.

(PUP-10238) Change default value of strict_hostname_checking to true

Previously our default value of strict_hostname_checking was false which
allowed matching dotted segments of a nodes certname (its CN in its
certificate) as well as the segments of its fqdn fact, or hostname +
domain fact.

This was for compatibility when fact based classification within a
site.pp was a more common pattern and node declarations were much less
powerful than they are now.

With the ability to use regular expressions in a node declaration the
auto segmenting is no longer needed and with the ability to use facts
directly, to use fact interpetation in hiera lookups, or create a custom
external node classifier the injecting of facts into the nodes "name" is
unneeded.

The desire is to remove the setting completely in Puppet 7, while
leaving it in 6 so those that depend on this behavior have time to
re-write their site.pps to the newer styles.

strict_hostname_checking setting is not marked deprecated completely
because it will cause deprecation notices on setting access, which
happens as part of normal compilation for now. However it does mark
"node_name" setting as deprecated completely because it is now only
referenced in code that by default will not run (and will only run if
users change strict_hostname_checking back to false).

This reverts commit a5ae3409.

(PUP-10227) Preserve expectation for http.finish

Stub the "Net::HTTP#started?" method so finish happens as expected. Protect
against Net::HTTP#finish being called twice, and ensure the "Closing connection"
debug message is printed after the redirect, since Pool#close_connection will be
a noop.

(PUP-10142) refactor settings initialization

This is a separate commit to keep the white space change
for all the settings contained.

Previous to this commit, the puppet settings defaults were loaded
when the defaults.rb file was required. That design makes it
difficult to generate new settings objects; additionally, code
that executes by simply requiring the file seems less than ideal.

This change stops the code from executing by simply requiring the
defaults.rb file, and refactors it to become a class method that
modifies a settings object that is passed in. As a result of this
refactor, the `Puppet.define_settings` method is no longer required
as a bridge to the @@settings object and is set as deprecated.

(PUP-10227) Close the HTTP connection

(PUP-10287) mailalias: comma inside commands fix

To prevent thundering herds, puppetserver may return Retry-After and ask
the agent to sleep.

When this happens, this commit closes the connection prior to sleeping.
It also ensures that closed connections are not added back to the pool.
This reduces resource usage on puppetserver.

(maint) simplify reading /opt/puppetlabs/server/pe_version

We don't need a regex to validate (presumably) already validated data.
Just transparently pass the data to the server fact.

(PUP-1537) add mark property for package

(maint) document the 'other' set_server_facts

Document the other set_server_facts in puppetserver.
