Slashdot Mirror
A Windows-Based Packaging Mechanism
FishWithAHammer writes "As part of my Google Summer of Code project, I'm working with WinLibre to develop a Debian-like software download system for free/open source software on the Windows platform. My reasoning is that open source software suffers from poor presentation. Most computer laymen, even those aware of open source software, often don't have any idea how to go about looking for it, but would use it if it were easier to access. What I have proposed is both a Debian-style packaging mechanism (capable of using Windows Installer MSIs or not, as the user wishes) and a software 'catalog' that takes the best aspects of Synaptic and Linspire's Click-N-Run system. Seamless, simple installation and removal of programs in as straightforward a way as apt-get (there will be a command-line tool as well). I'm posting to Slashdot to get the ideas of you lot who, while you may not be the target audience, can certainly provide insights that can be of value." Read on for more of this reader's ideas and questions.
There are areas that I'm personally not familiar with, and while I have done some research I would like the opinions of Slashdotters on some others. While at first I intend to set it up so that WinLibre (and I) run only one repository, I am curious as to how this sort of tool could be most useful to network administrators. Customizable repositories will be available; the code will be under the GPL, after all, so it'd be a little hard for them not to be available.
I'm also interested in the ideas of those who might be in a position to roll together packages. I intend to package a number of open-source language interpreters with the core software to allow special pre- and post-install scripts, as well as removal scripts. C#Script, Perl, and Python are definites, as is a Cygwin sh interpreter. We will have some program requirements — chief among them that no registry changes may be made by the program — but some of them, I fear, will require some flexibility; some programs really do require a way to edit the registry, for example, and I am considering offering some sort of tracked way to make registry changes so they can be rolled back on uninstallation of the program.
I'd love to hear what Slashdotters think of this. Think of it as a wishlist, but you don't get any damn ponies.

That's great of course, but it's the community and a selection of packages with mutually consistent packaging metadata which make systems like Debian and their derivatives so popular. The packaging system itself is an enabling technology.
I would say the big thing that I would look for in such a product would be a consistent (or even better, non-existent) use/removal of registry entries. I have dealt with so many so-called "professionally" done software pieces that upon uninstallation would leave several dozen registry entries. This seems terribly unnecessary, and if the so-called apt-get method could circumvent the registry (much like the run from USB flash drive programs) altogether, or at least make it a sure-fire thing to remove, instead of wipe-and-pray.
Good on you for trying to better the system man, I wish you the best of luck!
Uhm, let's compare signed repositories with grabbing those programs you need from websites, and quite a few of them use random services like download.com.
Quite a step forward in my book.
The creatures outside looked from Alt-Right to Antifa; but already it was impossible to say which was which.
For user-specified (or multiple fallback) repositories, you need nothing more complex than reading your base path(s) from a config file. Prepend that address to every file you download, and it will all go well.
For the bigger project, basically you just need a set of per-package install/uninstall scripts that check for dependancies (or no-longer-needed dependancies on uninstall), do their thing, and write themselves to a standardized catalog of installed software. Whether or not you can adapt Windows' list of such software, and the MSI interface in general, to your needs, I can't say offhand. I would think you can at least list the package therein, but I don't think that handles dependancy information quite as elegantly as you would want.
I see the biggest problem you'll have as coming from the poor regression testing done for Windows ports of FOSS - You may well need multiple (version-specific) instances of some dependancies installed at the same time, for different packages that use "working until version 2.8.10.4" features (or more of a nightmare, "working until KB935356").
Overall, I wish you luck with this. I think the Windows world has needed something like apt-get (with a mind-numbingly simple GUI) for a loooooong time.
I hope you're planning on making it interoperate with the cygwin packaging system. Cygwin's a great piece of software which is, IMO, let down by its obscure and difficult-to-use setup program. A new, friendlier way of installing and updating cygwin components would be a great asset. And if it worked with other OSS stuff as well, that would be a huge asset.
.exe that doesn't require your system, but which can interoperate with your system easily -- perhaps by having a version of your system that can wrap up a package with a copy of the relevant parts of itself in a .exe file.
One thing I would suggest is that you make it easy for somebody to package a standalone
It is not only the programmers' fault, though. Far too few users bother to suggest interface simplification,or even know how to advocate it. Merely complaining will not work - developers need to be shown that it can be done, and how, by means of mock-ups or illustrations. A few innovative user interface interested users could do wonders for many projects simply by drawing new user interfaces and submitting them to various free software projects, asking if they are interested in going a few rounds of design iterations with them. Often an outside eye, and interest in doing some adapting from both sides, is all that is needed.
Your complaint boils down to "some people make bad packages", which occurs on Linux as well, and is just the nature of software to be imperfect. I cannot count the number of bugs or non-working setups I've tracked down to bad packages, and even better, in the Linux world fixing such a bug once doesn't make it go away - it'll be repeated in 3 months time by a different distribution.
That would be nice, yes.
