mock 1.4.9

[Miroslav Suchý]

Hi,
I just released new version of mock. From the release notes:

https://github.com/rpm-software-management/mock/wiki/Release-Notes-1.4.9

Note:

In this release, there are several fixes to bootstrap feature. This is especially
important for users who run Mock on
EL7. Rich dependencies are now allowed in Fedora and maintainers are starting to use them.
So sooner or later, you will
be unable to build packages for Fedoras on EL7 host. Unless you start using bootstrap
feature (`--bootstrap-chroot`),
which is still by default off.


Features:
* Stdout and stderr in build.log has been split. All stderr output lines are prefixed by
`BUILDSTDERR:`
* There is a new config option `opstimeout`:

```
# Set timeout in seconds for common mock operations
# if 0 is set, then no time limit is used
# config_opts['opstimeout'] = 0
```

The default is 0, which means that Mock is waiting until command exit.

Bugfixes:
* Builds for EL5 are working again - EL5 is sensitive to order of params of adduser
[RHBZ#1535328](https://bugzilla.redhat.com/show_bug.cgi?id=1535328)
* Use correct builddep when bootstrap is used. Additionally, ccache is not installed into
bootstrap chroot.
[RHBZ#1540813](https://bugzilla.redhat.com/show_bug.cgi?id=1540813).
* User defined mounts are not mounted in bootstrap chroot.
* Detect if essential mounts are already mounted - previously, mock assumed that essential
mounts (procfs, sysfs) are
never mounted when mock starts up. That's not true, as multiple non-destructive mock
processes are allowed (`--shell`,
`--install`, etc.) to run concurrently. So when you use `mock --shell` and do a `mock
--install` in parallel, it breaks
your shell, because it unmounts its proc. This improves the situation by first asking
whether the mounts aren't there
already.
* fix quoting in sign_opts example in site-defaults.cfg
[RHBZ#1537797](https://bugzilla.redhat.com/show_bug.cgi?id=1537797).
* Honor the "cwd" flag when nspawn is being used and "chrootPath" is
not set.
* Do not produce a warning when we are using different PM for a bootstrap container.
* Default for config_opts['dnf_warning'] in site-defaults.cfg according to docs.

Additionally, there are several major changes in mock-core-config. This package is
independent now, and a new version
has been released two weeks ago and will be pushed to Fedora stable next week. I will
repeat here changes in that package:
* Fedora 28 configs has been added.
* `failovermethod=priority` has been removed for repos which use DNF. This is the only
method which DNF recognize and it
cannot be changed.
* Set `skip_if_unavailable=False` for all repos. If a repository is unreachable, then
build fails.


Following contributors contributed to this release:

* Barak Korren
* Michael Simacek
* Mikhail Campos Guadamuz
* mprahl
* Pavel Raiskup
* Todd Zullinger

Thank you.

Is it possible to override it (set to True) somehow in config? Sometimes it is useful to
have optional repo. 
And AFAIK skip_if_unavailable=False is default behaviour.

I would also like to be able to set this on occasion.

skip_if_unavailable=False is default behaviour for YUM. But for DNF the default behaviour
is True, ie. silently skip!
This was big surprise to me.

This is set per repo. I.e., in fedora-27-x86_64.cfg:

config_opts['yum.conf'] = """
...
[fedora]
name=fedora
metalink=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasev...
gpgkey=file:///usr/share/distribution-gpg-keys/fedora/RPM-GPG-KEY-fedora-27-primary
gpgcheck=1
skip_if_unavailable=False

[updates]
name=updates
metalink=https://mirrors.fedoraproject.org/metalink?repo=updates-released...
gpgkey=file:///usr/share/distribution-gpg-keys/fedora/RPM-GPG-KEY-fedora-27-primary
gpgcheck=1
skip_if_unavailable=False
...

When you add some other repo, manually, you do not need to specify
skip_if_unavailable=False.

I added this because it quite often happen in Copr, that there were issues with network
and main repo worked, but
updates did not. And then build failed with broken deps, or other mysterious errors, and
it was really hard to notice
that one repo is actually missing.
