sudo is certainly not needed for the run package (which in itself is hardly useful at all), so move that dependency into the devel package. Same for gawk. /opt/jw-pkg/bin/get-os.sh depends on it, but I don't see where else but in a -devel context that would matter. And if it breaks something, it is going to be an easy fix without awk.
invocations. Those invocations typically happen in the context of pkg-%install, so add that target, specializing the pkg-% target.
The problem this solves is that /etc/profile is currently read only once before bootstrapping all software on a pristine system is started. This might lead to the situation that package A has installed environment variable definitions into /etc/profile.d, package B needs them for building, but never gets to read them.
Add a function get_profile_env(), a function returning environment variables from /etc/profile. Pass add=True to add its contents to the existing environment dictionary, overwriting old entries, or pass False to get the pristine content.
Add a parameter "output_encoding" to run_cmd(). The parameter allows the caller to specify if the output encoding should be detected as is by passing None (the default), if the output should be returned as undecoded bytes by passing the special string "bytes", or if the output should be treated as the encoding with the specified name and decoded to strings.
Don't log an Exception as {e} but as str(e) producing nicer output. Or as repr(e) if a backtrace is requested, because to people who can read backtraces, type info might be of interest. Also, remove pointless time stamps, those belong into the logging framework.
dc945537 (pkg.sh log-install: Log %attr(0777, ...) for links) fixed packaging symlink for Debian-based distros, but produces a warning on RPM based distros: Links may not have explicit attributes, so go back to not specifying them at all for RPM.
To complement git-pull-maintainer with something more generic, also suitable for other SCMs, add the target pull-maintainer and make pkg-release-reinstall depend on it. Currently only visible in the context of pkg-% targets, scope might be expanded if need be.
Use pgit.sh to for the git-pull-% target. This should make git-pull-maintainer work. To limit the blast radius for now, only use it if the source user differs from the invoking user.
Multiple variables are redundantly defined both for a project and for the multiple-projects toplevel directory. Add a place to maintain them centrally, and add PGIT_SH as a first variable.
Add an init target. Use it if you want to tell the Makefile: _Just_ initalize the build machinery and nothing else, don't pull and build everything else you can. Not strictly necessary, most of the time pulling everything is what's wanted, and that does the init anyway.
The target pkg-delete-ours, invoked from the projects directory, should wipe all packages from the system which have been created and installed via jw-pkg.
Currently they are selected via url =~ janware. This is a default string which can be overridden by redefining JANWARE_PACKAGE_FILTER. This might not be the most generic name, but is kind of consistent and will be matched once all variables get renamed to a more generic naming scheme.
This currently does not get all packages: Some are not labeled with URLs matching "janware", because jw-pkg is only used as a convenient way to package other people's open source projects.
Rename jw.pkg.cmds.distro.backend.BackendCmd to Backend, because it's not necessarily a command, i.e. doesn't necessarily have a run() method. It's more of a distribution abstraction of the steps needed for for a specific command, the run() method itself is implemented in jw.pkg.cmds.distro.CmdXxx.
This commit is the beginning of a bigger move to change the distribution backend class hierarchy. At the end of this change set, the backend command should not derive the backend classes from a base specific to the respective distribution, but from an abstract base class specific to the command run. The distribution specifics are then going to be encapsulated in another class called "Util", an instance of which is going to be provided to the backend as .util member.
Move the body of BackendCmd.sudo() into a function. The rationale behind that is that its functionality is independent of the calling object for the most part, so having it in a function instead of a method is the more modular pattern.
This commit allows pgit.sh to target not only multiple projects below a projects-directory, but also one single project. If invoked from the toplevel directory of a project, it uses that as the only project it should deal with. This is meant to facilitate running the same VCS abstraction logic for one project as for many projects. The project or projects to deal with should probably be specified on the command line, but changing the auto-detection mechanism buys us what we want for now with low hassle.
Some variable names are too short for global scope ($p, $pdir, $pdirs), among others. For those mentioned: Make them longer and more descriptive.
Also add a variable project_name, which denotes what a project is in a remote repository, and which is currently but not necessarily always the same as the project directory.
Add more fields to the OS cascade returned by App.os_cascade, based on the ID field in /etc/os-release. This includes some new ones, prefixed by pkg-, revealing which package format is used.
apt-get install suggests it wants to be called with -f to clean up some mess left behind from a previous install. Adding -f in the hope add it to the install options by default. OTOH, it wants to be called that without arguments, not sure if always passing it along is a good idea.
The man page says:
-f, --fix-broken
Fix; attempt to correct a system with broken dependencies in place. This option, when used with install/remove, can omit any packages to permit APT to deduce a likely solution. If packages are specified, these have to completely correct the problem. The option is sometimes necessary when running APT for the first time; APT itself does not allow broken package dependencies to exist on a system. It is possible that a system's dependency structure can be so corrupt as to require manual intervention (which usually means using dpkg --remove to eliminate some of the offending packages). Use of this option together with -m may produce an error in some situations. Configuration Item: APT::Get::Fix-Broken.
Also turn the short options -yq into long options --yes --quiet for more obvious debugging if something goes awry.
Not logging any attribute for links, as it's now, breaks Debian's parser. So, log %attr(0777, $owner, $mode). This fixes the parser on the Debian side and hopefully leaves the RPM side intact.
