Description:
The libemu is a small library written in C offering basic x86 emulation and
shell-code detection using GetPC heuristics. Intended use is within network
intrusion/prevention detection and honeypots.

Comment 1 Michal Ambroz 2021-04-04 01:11:03 UTC
This request is to revive retired package and get it back to rawhide (is still in f33/f32/epel).

Package was retired based on https://bugzilla.redhat.com/show_bug.cgi?id=1863995 (FTBFS)
I managed to make it working again with new libtool and gcc10+.
Package is needed as dependency for dionaea honeypot.

Comment 2 Robert-André Mauchin 🐧 2021-04-04 20:07:08 UTC
 - Shouldn't you use %bcond_without within the Fedora condition? Py2 package are not allowed in Fedora anymore.

# libemu currently doesn't work with python3
%bcond_with     python3
%if 0%{?fedora} || ( 0%{?rhel} && 0%{?rhel} >= 7 )
%bcond_with     python3
%endif

Comment 3 Robert-André Mauchin 🐧 2021-04-04 20:37:27 UTC
 - You get the archive from DinoTools but you point the URL to buffer:

URL:            https://github.com/buffer/libemu
#               https://github.com/DinoTools/libemu/

 - make %{?_smp_mflags} → %make_build

 - Why is this touching needed:

%py3_install || touch %{buildroot}/%{python3_sitearch}/python3_install_failed
[ -f python3_build_failed ] && touch %{buildroot}/%{python3_sitearch}/python3_build_failed

 - This is not needed anymore:

%ldconfig_scriptlets

 - Globbing the entire %{python2_sitearch}/* and %{python3_sitearch}/* is now forbidden, please be more specific instead

 - In order to avoid unintentional soname bump, we recommend not globbing the major soname version, please be more specific here too:

%{_libdir}/*.so.2*

 - please remove the trailing spaces throughout the SPEC

 - Please BR gcc and make explicitly

 - Patch the obsolete M4 macros:


[!]: Package should not use obsolete m4 macros
     Note: Some obsoleted macros found, see the attachment.
     See: https://fedorahosted.org/FedoraReview/wiki/AutoTools

Thank you for review and comments. Updated package

> Shouldn't you use %bcond_without within the Fedora condition? Py2 package are not allowed in Fedora anymore.
py2 package is there for the RHEL7 where py2 module was already released in the past
py3 module is not working at the point, I hope to include it once it is ready - hence the conditions so I can try easily just by passing the argument

> - You get the archive from DinoTools but you point the URL to buffer:
Thanks for spotting - this is wrong, changed back to DinoTools.
I plan to migrate to buffer's repository in the future - it looks more living than the DinoTools, but it is not ready yet to switch over.

>  - make %{?_smp_mflags} → %make_build
OK

>  - Why is this touching needed:
It was ignoring the failed python3 build ... but you are right, this should go away and package build should fail if part is failing.

> - This is not needed anymore: %ldconfig_scriptlets
Still needed for EPEL7 ... I will state that explicit

> - Globbing the entire %{python2_sitearch}/* and %{python3_sitearch}/* is now forbidden, please be more specific instead
OK


> - In order to avoid unintentional soname bump, we recommend not globbing the major soname version, please be more specific here too:
OK
	

> - please remove the trailing spaces throughout the SPEC
removed


> AutoTools: Obsoleted m4s found AM_CONFIG_HEADER AC_PROG_LIBTOOL
Already part of patch 14

>- Please BR gcc and make explicitly
>- If your application is a C or C++ application you must list a
OK added. GCC was actually brought by libtool, but better to state that explicitly

>- Package does not use a name that already exists. Note: A package with this name already exists.
Yes ... that is the same package. 
Was kicked from rawhide due to FTBFS. 
Now trying to return.
