That was one of my reasons to choose this request.

No problem. Actually this is my first review and a funny story together ;-) I
started "5 days" ago and everybody told me to tell as much as possible about
myself and my package to find and convince a sponsor/reviewer. I just wanted to
give this tip/hind on because this request was waiting quite long.

Now to the real interesting stuff: review of firehol-1.273-5.fc11.src.rpm
(sha256sum 4ee2dd849a38948fc9c2ed8463089628429b9e81423633892b2b88e77ffdd61e)

[ OK ] MUST: rpmlint must be run on every package. The output should be posted
in the review.

$ rpmlint SPECS/firehol.spec SRPMS/firehol-1.273-5.fc11.src.rpm
RPMS/noarch/firehol-1.273-5.fc11.noarch.rpm 
firehol.noarch: E: non-readable /etc/firehol/firehol.conf 0640
firehol.noarch: E: subsys-not-used /etc/rc.d/init.d/firehol
2 packages and 1 specfiles checked; 2 errors, 0 warnings.

Actually firehol uses /var/lock/subsys where it touches "firehol" and
"iptables" when it starts. I guess rpmlint does not recognize that because it
is hidden in the bash script. A grep after "FIREHOL_LOCK_DIR" in
/etc/init.d/firehol explains this.

[ OK ] MUST: The package must be named according to the Package Naming
Guidelines .

[ OK ] MUST: The spec file name must match the base package %{name}, in the
format %{name}.spec unless your package has an exemption.

[ OK ] MUST: The package must meet the Packaging Guidelines .

[ OK ] MUST: The package must be licensed with a Fedora approved license and
meet the Licensing Guidelines .

[ OK ] MUST: The License field in the package spec file must match the actual
license.

[ OK ] MUST: 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 must be included in %doc.

[ OK ] MUST: The spec file must be written in American English.

[ OK ] MUST: The spec file for the package MUST be legible.

[ OK ] MUST: The sources used to build the package must match the upstream
source, as provided in the spec URL. Reviewers should use md5sum for this task.
If no upstream URL can be specified for this package, please see the Source URL
Guidelines for how to deal with this.

sha256sum:

[ OK ] MUST: The package MUST successfully compile and build into binary rpms
on at least one primary architecture.

[ OK ] MUST: If the package does not successfully compile, build or work on an
architecture, then those architectures should be listed in the spec in
ExcludeArch. Each architecture listed in ExcludeArch MUST have a bug filed in
bugzilla, describing the reason that the package does not compile/build/work on
that architecture. The bug number MUST be placed in a comment, next to the
corresponding ExcludeArch line.

Not relevant, since noarch.

[ OK ] MUST: All build dependencies must be listed in BuildRequires, except for
any that are listed in the exceptions section of the Packaging Guidelines ;
inclusion of those as BuildRequires is optional. Apply common sense.

No "BuildRequires" available. Only "Requires" which are OK.

[ OK ] MUST: The spec file MUST handle locales properly. This is done by using
the %find_lang macro. Using %{_datadir}/locale/* is strictly forbidden.

OK because no locales available.

[ OK ] MUST: Every binary RPM package (or subpackage) which stores shared
library files (not just symlinks) in any of the dynamic linker's default paths,
must call ldconfig in %post and %postun.

OK because only shell scripts get installed.

[ OK ] MUST: Packages must NOT bundle copies of system libraries.

[ OK ] MUST: If the package is designed to be relocatable, the packager must
state this fact in the request for review, along with the rationalization for
relocation of that specific package. Without this, use of Prefix: /usr is
considered a blocker.

OK because only shell scripts are used.

[ OK ] MUST: A package must own all directories that it creates. If it does not
create a directory that it uses, then it should require a package which does
create that directory.

$ rpmls RPMS/noarch/firehol-1.273-5.fc11.noarch.rpm | grep ^d
drwxr-xr-x  /etc/firehol
drwxr-xr-x  /etc/firehol/services
drwxr-xr-x  /usr/libexec/firehol
drwxr-xr-x  /usr/share/doc/firehol-1.273
drwxr-xr-x  /usr/share/doc/firehol-1.273/doc
drwxr-xr-x  /usr/share/doc/firehol-1.273/examples
drwxr-xr-x  /var/spool/firehol

[ OK ] MUST: A Fedora package must not list a file more than once in the spec
file's %files listings.

[ OK ] MUST: Permissions on files must be set properly. Executables should be
set with executable permissions, for example. Every %files section must include
a %defattr(...) line.

All permissions seem to be fine (checked via rpmls).

[ OK ] MUST: Each package must have a %clean section, which contains rm -rf
%{buildroot} (or $RPM_BUILD_ROOT).

[ OK ] MUST: Each package must consistently use macros.

[ OK ] MUST: The package must contain code, or permissable content.

[ OK ] MUST: Large documentation files must go in a -doc subpackage. (The
definition of large is left up to the packager's best judgement, but is not
restricted to size. Large can refer to either size or quantity).

[ OK ] MUST: If a package includes something as %doc, it must not affect the
runtime of the application. To summarize: If it is in %doc, the program must
run properly if it is not present.

[ OK ] MUST: Header files must be in a -devel package.

OK because only shell scripts are shipped.

[ OK ] MUST: Static libraries must be in a -static package.

OK like above.

[ OK ] MUST: Packages containing pkgconfig(.pc) files must 'Requires:
pkgconfig' (for directory ownership and usability).

OK since no pkgconfig is used.

[ OK ] MUST: If a package contains library files with a suffix (e.g.
libfoo.so.1.1), then library files that end in .so (without suffix) must go in
a -devel package.

[ OK ] MUST: In the vast majority of cases, devel packages must require the
base package using a fully versioned dependency: Requires: %{name} =
%{version}-%{release}

[ OK ] MUST: Packages must NOT contain any .la libtool archives, these must be
removed in the spec if they are built.

[ OK ] MUST: Packages containing GUI applications must include a
%{name}.desktop file, and that file must be properly installed with
desktop-file-install in the %install section. If you feel that your packaged
GUI application does not need a .desktop file, you must put a comment in the
spec file with your explanation.

[ OK ] MUST: Packages must not own files or directories already owned by other
packages. The rule of thumb here is that the first package to be installed
should own the files or directories that other packages may rely upon. This
means, for example, that no package in Fedora should ever share ownership with
any of the files or directories owned by the filesystem or man package. If you
feel that you have a good reason to own a file or directory that another
package owns, then please present that at package review time.

[ OK ] MUST: At the beginning of %install, each package MUST run rm -rf
%{buildroot} (or $RPM_BUILD_ROOT).

[ OK ] MUST: All filenames in rpm packages must be valid UTF-8.

[ OK ] SHOULD: If the source package does not include license text(s) as a
separate file from upstream, the packager SHOULD query upstream to include it.

[ NA ] SHOULD: The description and summary sections in the package spec file
should contain translations for supported Non-English languages, if available.

[ OK ] SHOULD: The reviewer should test that the package builds in mock.

Builds fine with mock on fedora-11-ppc.

[ NA ] SHOULD: The package should compile and build into binary rpms on all
supported architectures.

Since it is a noarch package it's not really interesting I guess. Only shell
scripts get copied no compilation at all.

[ OK ] SHOULD: The reviewer should test that the package functions as
described. A package should not segfault instead of running, for example.

More or less OK. I did a few starts and stops. The rules are loaded properly.

[ OK ] SHOULD: Usually, subpackages other than devel should require the base
package using a fully versioned dependency.

[ OK ] SHOULD: The placement of pkgconfig(.pc) files depends on their usecase,
and this is usually for development purposes, so should be placed in a -devel
pkg. A reasonable exception is that the main pkg itself is a devel tool not
installed in a user runtime, e.g. gcc or gdb.

OK since pkgconfig isn't used.

[ OK ] SHOULD: If the package has file dependencies outside of /etc, /bin,
/sbin, /usr/bin, or /usr/sbin consider requiring the package which provides the
file instead of the file itself.

I noticed one thing during extensive testing. A few arguments to the init
script aren't supported. The init script guidlines
(https://fedoraproject.org/wiki/Packaging/SysVInitScript#Required_Actions)
insist on the following missing arguments:

- try-restart (I guess this is not a big problem since condrestart is
available)
- reload (may be negligible too)

Additionally condrestart didn't work for me like expected. For example:

$ /etc/init.d/firehol start
FireHOL: Saving your old firewall to a temporary file:     [  OK  ]
FireHOL: Processing file /etc/firehol/firehol.conf:        [  OK  ]
FireHOL: Activating new firewall (41 rules):               [  OK  ]

$ ls -l /var/lock/subsys/firehol
-rw-r--r--. 1 root root 0 2009-09-22 17:36 /var/lock/subsys/firehol

$ /etc/init.d/firehol stop
FireHOL: Clearing Firewall:                                [  OK  ]

$ ls -l /var/lock/subsys/firehol
ls: cannot access /var/lock/subsys/firehol: No such file or directory

$ iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

$ /etc/init.d/firehol condrestart
FireHOL: Saving your old firewall to a temporary file:     [  OK  ]
FireHOL: Processing file /etc/firehol/firehol.conf:        [  OK  ]
FireHOL: Activating new firewall (41 rules):               [  OK  ]

$ iptables -L
Chain INPUT (policy DROP)
target     prot opt source               destination         
ACCEPT     all  --  anywhere             anywhere
... and a lot of rules are up


I would have expected that condrestart does nothing since I stopped the service
before. Maybe this is a bug in upstream?

Otherwise looks OK.
