Parses /var/lib/dpkg/status (and/or any other needed files) and displays a list of packages explicitly installed by the user
The packageScout package is built in Docker to ensure native compliance with Ubuntu while being agnostic of the developer's host platform. It is built by default in the initial generation of the Docker image (destination /app/src/deb_dist/*.deb), but can be easily rebuilt by running an interactive container and executing the build scripts.
Build a Docker image with the Dockerfile in the head directory:
docker build -t packagescout .
This builds the product by default in /app/src/deb_dist/*.deb.
- Create a temporary docker container called
tempContainerusing thepackagescoutimage - Copy the .deb file into the host's product folder
- Remove the temporary docker container (or keep it if you like)
docker run --name tempContainer packagescout /bin/true
docker cp tempContainer:/app/src/deb_dist/python3-packagescout_0.1-1_all.deb ./product/python3-packagescout_0.1-1_all.deb
docker rm tempContainer
Replace the package-name as necessary. As of writing, this is correct for the current version.
Docker containers can be run and entered through the interactive option -it. This can be useful for development and building without another lengthy docker build command.
docker run -it packagescout /bin/bash
-v <hostpath>:<containerpath> can be used to mount a host directory to the container, which can be helpful for saving built packages outside of the docker container. I typically use -v C:\Users\okina\packageScout:\app2 to mount my local directory to the container's /app2 folder:
docker run -it -v C:\Users\okina\packageScout:/app2 packagescout /bin/bash
Copy the package into your user's machine and install with dpkg:
dpkg -i python3-packagescout_0.1-1_all.deb
The folder product/ contains a Docker file for creating a test environment. This is a simple ubuntu18.04 environment with python3 and the contents of the product/ folder copied into the image's /app directory. The Docker image can be built by entering the product/ directory and running:
docker build -t product .
It can be entered interactively:
docker run -it product /bin/bash
Note that if a new package is to be tested, the image will have to be rebuilt or in a mounted volume when a container is started.
Remove the package with dpkg's -P option:
dpkg -P python3-packagescout
The packageScout package can now be used in python3 by importing it, creating a packageScout class, and running the exec() function. The file product/test.py provides an example of this, shown below:
import packageScout
ps = packageScout.packageScout()
ps.exec()
- provide flexibility in handling version names
- use scripts to recognize version
- Fix functionality
- several other packages are being added
- my own package isn't being counted (source is present)
- Leads
- explore other files/directories
- look at history
- https://linuxhint.com/see-dpkg-apt-history/ indicates that
/var/log/dpkg.logmay be a good place to look forinstallinstances in the logs, but my local version shows a lot of derived installations.
- https://linuxhint.com/see-dpkg-apt-history/ indicates that
- Add more robust testing, ideally with python's unit-testing framework
- Python creates docker images from custom docker files, installs the script, and checks output. This will be slow.
The tbuild.sh script is used to automate builds in the src directory of the Docker container. Details are below.
I found python's stdeb to be the most straightforward method for building a debian package.
A python package is first built:
python3 -m build
- will build
.tar.gzand.whlfiles indist/folder
The root user needs to have ownership and permissions in the local directory.
chown root:root -R .
chmod 0755 .
py2dsc will convert a distutils-built source tarball into a Debian source package.

Description: fast, scalable, distributed revision control system
Git is popular version control system designed to handle very large
projects with speed and efficiency; it is used for many high profile
open source projects, most notably the Linux kernel.
.
Git falls in the category of distributed source code management tools.
Every Git working directory is a full-fledged repository with full
revision tracking capabilities, not dependent on network access or a
central server.
.
This package provides the git main components with minimal dependencies.
Additional functionality, e.g. a graphical user interface and revision
tree visualizer, tools for interoperating with other VCS's, or a web
interface, is provided as separate git* packages.

Many new features have been added: multi level undo, syntax
highlighting, command line history, on-line help, filename
completion, block operations, folding, Unicode support, etc.
.
This package contains a version of vim compiled with a rather
standard set of features. This package does not provide a GUI
version of Vim. See the other vim-* packages if you need more

Version: 0.17025-1

Description: Perl module for error/exception handling in an OO-ish way
The Error module provides two interfaces. Firstly "Error" provides a
procedural interface to exception handling. Secondly "Error" is a base class
for errors/exceptions that can either be thrown, for subsequent catch, or can
simply be recorded.
.
Errors in the class "Error" should not be thrown directly, but the user
should throw errors from a sub-class of "Error".
.
Warning: Using the "Error" module is no longer recommended due to the
black-magical nature of its syntactic sugar, which often tends to break. Its
maintainers have stopped actively writing code that uses it, and discourage
people from doing so.
.
Recommended alternatives are Exception::Class (libexception-class-perl),
Error::Exception (not packaged), TryCatch (libtrycatch-perl), and Try::Tiny
(libtry-tiny-perl).
