WildFly 10 rpmbuild - wildfly-10

I am building a custom RPM for WildFly 10. I am stuck on deploying the systemd service. The spec file is able to deploy the code as well as create a user, however, no matter what avenue I try, I cannot get the RPM to create the service. I have tried install -m 644 but rpmbuild has tries finding the file, even if I specify full path:
e.g. install -m 644 %{buildroot}/opt/%{name}/docs/contrib/scripts/systemd/%{name}.service %{buildroot}/usr/lib/systemd/system/%{name}.service
I have also tried a series of systemd scriptlets as noted in https://fedoraproject.org/wiki/Packaging:Scriptlets, but that does nothing (the RPM will build with exit 0 status, but the service is never created). Any assistance would be appreciated.

Does the "%defattr" directive affect the "%post" section also in rpm spec file?

I have a .spec file with code somewhat like this:
%defattr(-,xyz, xyz)
%verify(md5 size mtime mode) %attr(755, xyz, xyz) /usr/bin/app1
%verify(md5 size mtime mode) %attr(755, xyz, xyz) /usr/bin/app2
mkdir -p /apps/1/logs
mkdir -p /apps/2/logs
mkdir -p /apps/3/logs
mkdir -p /apps/4/logs
mkdir -p /apps/5/logs
ln -sf /usr/bin/app1 /usr/bin/app3
touch /home/xyz/abc.log
will the %defattr also affect the default attributes of files and directories getting created in the post section??
No. You'll need to explicitly chown/chmod anything you do in %post. It's preferred to not have them in %post because things can break that way (like rpm -V). Why wouldn't you want that to be done in %build?

Retrieve rows in DB corresponding to particular ID using kubectl

I am trying to fetch the no. of rows for a particular ID using kubectl but instead getting some extra data.
kubectl exec abc-db-0 -n cicd --kubeconfig /root/admin.conf -- bash -c "psql -U postgres -d db -f /tmp/queryInstanceId.sql -v v1=full_test | grep [0-9]"
Actual Output of above command:
Defaulting container name to abc-db.
Use 'kubectl describe pod/abc-db-0 -n cicd' to see all of the containers in this pod.
(0 rows)
Expected Output:
(0 rows)
Could anyone please let me know what I am doing wrong here?
The first 2 lines always comes when we login to the DB manually but in output I only want (0 rows)
The first two lines are output by kubectl exec because the Pod has multiple containers. It is sort of a warning that it picked the first one, which might not be the one you wanted use.
You can specify the target container in your command (-c containername):
kubectl exec abc-db-0 -n cicd --kubeconfig /root/admin.conf -c abc-db -- bash -c "psql -U postgres -d db -f /tmp/queryInstanceId.sql -v v1=full_test | grep [0-9]"
Or you can redirect the standard error with kubectl ... 2>/dev/null (os specific):
kubectl exec abc-db-0 -n cicd --kubeconfig /root/admin.conf -c -- bash -c "psql -U postgres -d db -f /tmp/queryInstanceId.sql -v v1=full_test | grep [0-9]" 2>/dev/null

extracting and creating ipk files

ipk packages are the intallation packages used by opkg.
I'm trying to extract the contents of one of them and also create my own ipk.
I've read that I should be able to untar them but that is not true.
I've tried:
tar -zxvf mypack.ipk
and I get:
zip: stdin: not in gzip format
I've also tried:
tar -xvf mypack.ipk
and I get:
tar: This does not look like a tar archive
I've found that most of the information on the internet regarding ipk's are inaccurate.
My ipk was generated by bitbake. I'm having a hard time with bitbake and want to avoid using it.
Any ideas on how to extract and how to create ipk files? A simple template with a single package would be useful to have.
I figured it out.
You can extract the main package with the ar x command, then extract the control.tar.gz with the tar -zxf command.
I have tested "ar x package-name.ipk" command but it didn't help
I found bellow command which worked perfectly
tar zxpvf package-name.ipk
This extracts three files:
use the same command to open data.tar.gz and control.tar.gz files
for more information refer to
You need to create a control file, and then do some archiving using tar and ar. In my case, I was distributing just python scripts, so there was no architecture dependency. You should check the control and Makefile into version control, and delete all the other intermediate files.
Here are the contents of control
Package: my-thing-python
Version: 1.0
Description: python scripts for MyCompany
Section: extras
Priority: optional
Maintainer: John
License: CLOSED
Architecture: all
OE: my-thing-python
Homepage: unknown
Depends: python python-distutils python-pyserial python-curses python-mmap python-ctypes
Source: N/A
Here is my Makefile which sits in the same directory as all my python scripts.
all: my-thing-python.ipk
rm -rf ipk
mkdir -p ipk/opt/my-thing-python
cp *.py ipk/opt/my-thing-python
tar czvf control.tar.gz control
cd ipk; tar czvf ../data.tar.gz .; cd ..
echo 2.0 > debian-binary
ar r my-thing-python.ipk control.tar.gz data.tar.gz debian-binary
clean: FORCE
rm -rf ipk
rm -f control.tar.gz
rm -f data.tar.gz
rm -f my-thing-python.ipk
Extracting with these commands:
Extract the file by running the command:
ar -xv <.ipk file>
Extract the control.tar.gz file by running the command:
tar -zxvf control.tar.gz
data.tar.gz : untar by running the command:
tar –zxvf data.tar.gz
If you want a list of files in an ipk, you can do something like:
for f
tar -x -z -f $f ./data.tar.gz -O | tar tvzf -
-O is extract to standard output.
ipk files used to be AR (like DPKG), but are now tgz.
I feel that some dpkg utility ought to cope with ipkg files, but I haven't found the right one.

How to replace MacPort's libiconv with Mac's default 64-bit version?

MacPorts installed "libiconv #1.14_0+universal" as a dependency on my system. This happens to be a 32-bit flavor and it started causing issue when I tried to compile a voice recognition software called Simon Listens.
While googling I found out that that Mac actually ships with a 64-bit flavor of libiconv by default and I was able to locate the said files on my system:
$ find /usr/lib -name libiconv*
In order to use the system library, the quickest way I could think of was to uninstall MacPort's version of libiconv so that the system's library would end up getting selected as a fallback as it has to present (my guess) somewhere downstairs on the PATH already.
But that failed due to dependecies:
$ sudo port uninstall libiconv #1.14_0+universal
Unable to uninstall libiconv #1.14_0+universal, the following ports depend on it:
So now my question is how can I tell MacPort to replace its dependency graph to point to and use the library already on my system?
Another approach to avoid MacPorts libiconv issues would be to build simon against a fresh MacPorts system plus the necessary packages such as cyrus-sasl2, zlib, portaudio and kdesdk4 in a custom location, e. g. /opt/macports-simon.
The following code worked for me on my machine running Mac OS X 10.6.8:
# compile simon on Mac OS X 10.6.8 using MacPorts for the installation of zlib, portaudio and kdesdk4

LXR for Ruby interpreter?

I'm trying to track down a bug caused by the intersection of MRI 1.8.7 and libxml-1.1.3, and I need to do some digging around in the codebase of the Ruby interpreter itself. The SVN browser is of limited utility; what I'd really like is to use LXR, which hyperlinks a C codebase for easy navigation, e.g. http://lxr.linux.no/perl+perl-5.10.1/utf8.c
I can certainly set up LXR on my machine, but does anyone know if there's a public LXR for Ruby out there? Google is not very helpful: http://www.google.com/search?ie=UTF-8&q=lxr+ruby
I still haven't found a public LXR for MRI, so I set up one on my machine. Here's how to do it on Ubuntu 10.10:

Its not LXR, but I did a lot of that recently and found Understand extremely helpful. It'll let you click on any symbol and go to a definition/declaration and do simple call graphing and other static analysis. I just wish it supported Ruby source too.
On another note, libxml is still hopelessly broken, if you can migrate to Nokogiri it'll save you a lot of grief. Their APIs are very similar.
