--- Comment #8 from Andy Lutomirski <luto@xxxxxxx> ---
It looks like parallel-installing the 64-bit and 32-bit versions would be quite
useful.  That would mostly involve moving everything to %{_libdir}, possibly
all in a subpackage, and having a separate package with symlinks.  The arch
packages should possibly also install an afl-fuzz-64 or afl-fuzz-32 symlink in
%{_bindir}, too.  (Feel free to disagree with me here.)

I'm ambivalent about the sed vs make args.  I think make args would be nicer
(as noted above).

The source URL is actively problematic.  Downloading it right now results in a
tarball that is materially different (docs only, fortunately) from the one in
your SRPM.  Can you use a different URL or none at all and ask upstream to
provide usable download links?


Package Review
==============

Legend:
[x] = Pass, [!] = Fail, [-] = Not applicable, [?] = Not evaluated
[ ] = Manual review needed


Issues:
=======
- Sources used to build the package match the upstream source, as provided in
  the spec URL.
  Note: Upstream MD5sum check error, diff is in /home/luto/devel/fedora/afl
  /american-fuzzy-lop/diff.txt
  See: http://fedoraproject.org/wiki/Packaging/SourceURL
- All build dependencies are listed in BuildRequires, except for any that are
  listed in the exceptions section of Packaging Guidelines.
  Note: These BR are not needed: sed
  See: http://fedoraproject.org/wiki/Packaging/Guidelines#Exceptions_2


===== MUST items =====

C/C++:
[x]: Package does not contain kernel modules.
[x]: Package contains no static executables.
[x]: Package does not contain any libtool archives (.la)
[x]: Rpath absent or only used for internal libs.

Generic:
[x]: Package is licensed with an open-source compatible license and meets
     other legal requirements as defined in the legal section of Packaging
     Guidelines.
[x]: License field in the package spec file matches the actual license.
     Note: Checking patched sources after %prep for licenses. Licenses found:
     "Apache (v2.0)", "Unknown or generated". 4 files have unknown license.
     Detailed output of licensecheck in /home/luto/devel/fedora/afl/american-
     fuzzy-lop/licensecheck.txt
[!]: Package requires other packages for directories it uses.
     Note: No known owner of /usr/lib64/afl

^^^ The package must own %{_libdir}/afl

[!]: Package must own all directories that it creates.
     Note: Directories without known owners: /usr/lib64/afl
[!]: %build honors applicable compiler flags or justifies otherwise.

^^^ %{optflags} isn't being honored.  Something like make CFLAGS="%{optflags}"
could work.

[x]: Package contains no bundled libraries without FPC exception.
[x]: Changelog in prescribed format.
[x]: Sources contain only permissible code or content.
[x]: Package contains desktop file if it is a GUI application.
[x]: Development files must be in a -devel package
[x]: Package uses nothing in %doc for runtime.
[x]: Package consistently uses macros (instead of hard-coded directory names).
[x]: Package is named according to the Package Naming Guidelines.
[x]: Package does not generate any conflict.
[x]: Package obeys FHS, except libexecdir and /usr/target.
[x]: If the package is a rename of another package, proper Obsoletes and
     Provides are present.
[!]: Requires correct, justified where necessary.

I think that BR: sed is unnecessary, though.

[x]: Spec file is legible and written in American English.
[x]: Package contains systemd file(s) if in need.
[x]: Useful -debuginfo package or justification otherwise.
[x]: Package is not known to require an ExcludeArch tag.

It does require it, and it's there.

[x]: Large documentation must go in a -doc subpackage. Large could be size
     (~1MB) or number of files.
     Note: Documentation size is 686080 bytes in 25 files.
[ ]: Package complies to the Packaging Guidelines

See notes above

[x]: Package successfully compiles and builds into binary rpms on at least one
     supported primary architecture.
[x]: Package installs properly.
[x]: Rpmlint is run on all rpms the build produces.
     Note: There are rpmlint messages (see attachment).
[x]: If (and only if) the source package includes the text of the license(s)
     in its own file, then that file, containing the text of the license(s)
     for the package is included in %doc.
[x]: Package does not own files or directories owned by other packages.
[x]: Package uses either %{buildroot} or $RPM_BUILD_ROOT
[x]: Package does not run rm -rf %{buildroot} (or $RPM_BUILD_ROOT) at the
     beginning of %install.
[x]: Macros in Summary, %description expandable at SRPM build time.
[x]: Package does not contain duplicates in %files.
[x]: Permissions on files are set properly.
[x]: Package use %makeinstall only when make install' ' DESTDIR=... doesn't
     work.
[x]: Package is named using only allowed ASCII characters.
[x]: Package do not use a name that already exist
[x]: Package is not relocatable.
[x]: Spec file name must match the spec package %{name}, in the format
     %{name}.spec.
[x]: File names are valid UTF-8.
[x]: Packages must not store files under /srv, /opt or /usr/local

===== SHOULD items =====

Generic:
[!]: Uses parallel make %{?_smp_mflags} macro.

Justified in the spec.

[x]: If the source package does not include license text(s) as a separate file
     from upstream, the packager SHOULD query upstream to include it.
[x]: Final provides and requires are sane (see attachments).
[ ]: Package functions as described.

Will test tomorrow.

[x]: Latest version is packaged.
[x]: Package does not include license text files separate from upstream.
[x]: Description and summary sections in the package spec file contains
     translations for supported Non-English languages, if available.
[-]: %check is present and all tests pass.


[x]: Packages should try to preserve timestamps of original installed files.
[x]: Packager, Vendor, PreReq, Copyright tags should not be in spec file
[x]: Sources can be downloaded from URI in Source: tag
[x]: Reviewer should test that the package builds in mock.
[x]: Buildroot is not present
[x]: Package has no %clean section with rm -rf %{buildroot} (or
     $RPM_BUILD_ROOT)
[x]: Dist tag is present (not strictly required in GL).
[x]: No file requires outside of /etc, /bin, /sbin, /usr/bin, /usr/sbin.
[x]: SourceX is a working URL.
[x]: Package should compile and build into binary rpms on all supported
     architectures.
[x]: Spec use %global instead of %define unless justified.

===== EXTRA items =====

Generic:
[x]: Rpmlint is run on all installed packages.
     Note: There are rpmlint messages (see attachment).
[x]: Large data in /usr/share should live in a noarch subpackage if package is
     arched.
