=head1 NAME

sbopkglint - check Slackware binary packages for common errrors.

=head1 SYNOPSIS

B<sbopkglint> [-k] [-i] [-s] [-c | --color] [-m | --mono] [I<package.t?z> I<...>]

=head1 DESCRIPTION

B<sbopkglint> installs a Slackware package to a temporary directory, then
examines the contents. It finds lots of common problems that aren't
always noticed by SBo script maintainers or the admins.

This is for built packages. If you want to lint your build scripts,
use B<sbolint>(1) instead.

With no package arguments, it looks for a SlackBuild in the current
directory, extracts the PRINT_PACKAGE_NAME information, and tries
to find a package in $OUTPUT (/tmp by default). If found, it checks
that package. It's up to you to know whether the package needs to be
rebuilt (e.g. if you've edited the SlackBuild since the package was
built).

With arguments, it checks the given packages. These must be
supported Slackware package files (.tgz, .txz, .tlz, etc). There's no
requirement that these have to be SBo packages, but a couple of the
tests (e.g. the check for $PRGNAM.SlackBuild in the doc dir) might not
apply to non-SBo builds.

Diagnostics will be logged to B<stdout> and B<stderr>. Exit status will
be 0 if all tests passed, non-zero otherwise.

This script must run as root. If you run it as a normal user, it tries
to re-execute itself via sudo(8) before installing any packages. If
you dislike sudo, you can always run it as root.

Note that B<sbopkglint> is intended to help you, not control you. If
your build fails the tests, and you're 100% sure it's correct, please
contact the maintainer (B<urchlay@slackware.uk>) and explain the
situation. Most likely, B<sbopkglint> will be modified to accomodate your
code, unless something really is wrong with it.

=head1 OPTIONS

Do not bundle options. Use e.g. B<-k -i>, not B<-ki>.

=over 4

=item B<-k>

Keep the temporary package install directory instead of deleting it on exit.

=item B<-i>

Disable the "useless-looking install instructions" test. This is
intended for SBo admins mass-linting a ton of packages. INSTALL in
the doc dir is something that exists in thousands of existing builds,
and it's not a major problem. New builds and updates should be linted
without this option, however.

=item B<-s>

Disable the check for /usr/doc/$PRGNAM-$VERSION/$PRGNAM.SlackBuild.
For use with non-SBo packages (including core Slackware packages).

=item B<-c>, B<--color>

Colorize the output (green I<OK>, red I<FAILED>, etc). Default is to use
color only when B<stdout> is a terminal.

=item B<-m>, B<--mono>

Do not colorize the output, even if B<stdout> is a terminal.

=item B<--doc>, B<--help>

View this documentation using perldoc(1), which generally uses your
pager (e.g. less(1) or more(1)) to display it.

=item B<--man>

Convert this documentation to a man page, on B<stdout>.

=item B<--version>

Print the B<sbopkglint> version number on B<stdout> and exit.

=back

=head1 EXIT STATUS

0 (success) if all tests passed for all packages, non-zero if there
were any test failures (or if installpkg failed for some reason).

=head1 FILES

=over 4

=item B<sbolint.d/*.t.sh>

These are the actual tests. They're installed to
I<PREFIX>/share/sbo-maintainer-tools, and they're sourced by
B<sbopkglint> at runtime. Each test script begins with (hopefully)
useful comments that go into more detail than the documentation here.

=back

=head1 TESTS

=head2 pre-doinst

This test is done before B<doinst.sh> is run, unlike the rest of
the tests. It checks for the existence of various files that should
not be in the package, but are OK if generated by B<doinst.sh>,
e.g. I</usr/info/dir>. It also checks for the existence of symlinks
in the package (these also must be created by B<doinst.sh>, not
included in the package archive).

=head2 basic-sanity

=over 4

=item B<->

Top-level directories inside the package must be recognized ones,
such as /bin /etc /usr /opt. Packages shouldn't be installing files
in /tmp, /dev, or /home... and they really shouldn't be inventing
new top-level directories.

=item B<->

The documentation directory must exist and be correctly named, as
/usr/doc/$PRGNAM-$VERSION.

=item B<->

The documentation directory must contain $PRGNAM.SlackBuild. This
check can be disabled with the B<-s> option.

=item B<->

The directories /usr/local, /usr/share/doc, /usr/share/man, /usr/etc
are not allowed in SBo packages.

=item B<->

Some directories (e.g. /usr/bin) may not contain subdirectories.

=item B<->

Some directories (e.g. /usr/share) must *only* contain subdirectories.

=item B<->

All files in /bin, /usr/bin, /sbin, /usr/sbin must be executable (have
at least one +x bit set).

=item B<->

Some directories (e.g. /usr/man, /usr/share/applications) must not
contain files with executable permissions. /usr/doc is not in this
list; neither is /etc (too many existing packages install +x files
there).

=item B<->

Broken symlinks may not exist.

=item B<->

Absolute symlinks may not exist (they should be converted to
relative symlinks). This may seem like nitpicking, but packages
may be installed somewhere besides / (the root dir) with the
-root option to installpkg. If /usr/bin/foo is a link to /usr/bin/bar,
it should be a link to just bar.

=back

=head2 docs

=over 4

=item B<->

Documentation must be installed to /usr/doc/$PRGNAM-$VERSION. If
there's any other directory under /usr/doc, it's incorrect. Some
builds use mis-named doc directories (if it hasn't been fixed by
now, an example is gcc5, which installs docs to /usr/doc/gcc-$VERSION
when it should be gcc5-$VERSION).

=item B<->

Documentation files must be readable by everyone, and owned by root:root.

=item B<->

Doc dir shouldn't contain empty files (0 bytes in length).

=item B<->

Doc dir shouldn't contain install instructions. Specifically, files
named INSTALL, INSTALL.*, or install.txt are flagged (it's impossible
to make this test 100% perfect). This check can be disabled with
the B<-i> option.

=item B<->

Any *.pdf files found in the doc dir are checked with B<pdfinfo> to
make sure they really are PDF files, and not corrupt/damaged.

=back

=head2 noarch

=over 4

=item B<->

If a package has its architecture set to "noarch", it must not contain
any ELF binaries/libraries.

=back

=head2 arch

=over 4

=item B<->

If a package has its architecture set to i?86 or x86_64, all ELF
binaries/libraries must be for the correct arch (no 32-bit code in
64-bit packages, and vice versa).

=item B<->

If a package is i?86, it must not contain /usr/lib64.

=item B<->

If a package is x86_64 and contains shared libraries, they must be
in /lib64 or /usr/lib64 (not /lib or /usr/lib).

=back

=head2 lafiles

=over 4

=item B<->

Packages are no longer allowed to contain libtool archive files (.la)
in /lib, /lib64, /usr/lib, or /usr/lib64. However, subdirectories
such as /usr/lib64/someprogram/ are not checked, since some applications
which use plugins actually use the .la files.

=back

=head2 manpages

=over 4

=item B<->

All man pages must be readable by everyone, and owned by root:root.

=item B<->

All man pages must be gzipped.

=item B<->

All man pages must be in /usr/man/man[1-9n] or /usr/man/<lang>/man[1-9n].

=item B<->

Man page directories must be mode 755, owned by root:root.

=item B<->

The section numbers in man page filenames must match the section number
in the directory name (e.g. /usr/man/man1/ls.1.gz is OK,
/usr/man/man1/tetris.6.gz is an error).

=item B<->

Man pages must actually be man pages (troff markup).

=back

=head2 desktop

=over 4

=item B<->

If there are .desktop files, doinst.sh must run update-desktop-database.

=item B<->

.desktop files must be mode 644, owned by root:root. Slackware's KDE
packages actually break this rule (they install executable .desktop
files), but SBo packages are not allowed to.

=item B<->

Only .desktop files are allowed in /usr/share/applications.

=item B<->

.desktop files must be valid, according to the desktop-file-validate
command. Only actual errors count; warnings don't cause this test to
fail.

=back

=head2 newconfig

=over 4

=item B<->

Any files (outside of /usr/doc) with names ending in .new are flagged.
This might be a bit too restrictive (possibly only check /etc and
/usr/share?)

=back

=head2 doinst

=over 4

=item B<->

If there are icons in /usr/share/icons, .desktop files in /usr/share/applications,
or glib2 schemas in /usr/share/glib-2.0/schemas, there must be a doinst.sh
with appropriate command(s), e.g. update-desktop-database, gtk-update-icon-cache,
glib-compile-schemas.

=back

=head2 icons

=over 4

=item B<->

Files in /usr/share/pixmaps and /usr/share/icons/hicolor must be known
image file types (PNG, SVG, JPEG, etc). Their filename extensions must
match the image type (e.g. file.png must actually be a PNG and not
some other MIME type).

=item B<->

Image files in /usr/share/icons/hicolor/<size>x<size>/* must actually be
the correct pixel size.

=back

=head1 BUGS

Probably many. This is still a work in progress.

One known problem is that the same file can fail multiple tests. E.g.
if you have a man page that's installed executable, it will fail both
the basic-sanity test and the manpages test. This isn't really a huge
problem, so it might not be fixed any time soon.
