Yes, I can add that. However, note that 0install uses the domain name
(raw.githubusercontent.com) as the context for trusting the GPG key,
so it might be better to use a domain that isn't shared with other
people (e.g. https://akavel.github.io/) for hosting the feeds.

[Zero-install-devel] How to add my feeds to 0mirror?

[Mateusz C. <cza...@gm...>]

Hi!
What is the way to add my feeds catalog to the 0mirror website? Should I
just link the catalog & public key here? If so, IIUC they are:

catalog:
https://raw.githubusercontent.com/akavel/0catalog/master/catalog.xml
key:
https://raw.githubusercontent.com/akavel/0catalog/master/8AA3DD6702E1B8C1.gpg

Thanks,

Re: [Zero-install-devel] source code distribution

[Bastian E. <ba...@ei...>]

Hi Konstantin,

the latest version of 0install for Linux is 2.17, so 2.12.3 is indeed a bit old. You could try uninstalling 0install using your distribution's package manager and then installing the latest version like this:

curl -O https://get.0install.net/0install.sh && chmod +x 0install.sh
sudo ./0install.sh install local

Bastian

Hi Bastian!

Thank you for the reply!
I have executed "curl https://apps.0install.net/gui/blender-linux.xml" and it produces no error message for me.
Could that be an outdated version of 0install? I am on Linux with 0install 2.12.3-1 native deb package.

Re: [Zero-install-devel] source code distribution

[Bastian E. <ba...@ei...>]

Hi Konstantin,

https://apps.0install.net/ uses a Let's Encrypt certificate that's automatically set up by GitHub Pages. The issue you are encountering is probably related to this: https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/

To verify, could you try running "curl https://apps.0install.net/gui/blender-linux.xml" and see if it produces a similar error message. If so, the solution would probably be to update your Linux distribution's CA certificates package.

Hope this helps.

Regards
Bastian

[Zero-install-devel] Zero Install for Windows 2.20.0 released

[Bastian E. <ba...@ei...>]

Hello all,

I recently published Zero Install for Windows 2.20.0
(https://github.com/0install/0install-win/releases/tag/2.20.0).

This version has some cool new features to speed up fetching new
implementations:

- .zip and .tar.* archives are now extracted while downloading without the
need for intermediate temporary files.

- Manifest digests are now calculated while extracting archives. This saves
time and reduces disk IO, because files don't need to be written to disk and
then read again.

Other improvements:

- Unix executable bits on Windows are now inferred from .manifest files.
This removes the need for separate .xbit files.

- Feed validation has been improved. This leads to clearer error messages
explaining which part of a feed cannot be processed.

As always, you can update to the latest version by running:

0install self update

You can also try this out on Linux and macOS, by running the cross-platform
(.NET-based) part of Zero Install for Windows like this:

0install run https://apps.0install.net/0install/0install-dotnet.xml run
https://example.com/some-feed.xml

Regards
Bastian

Re: [Zero-install-devel] source code distribution

[Dirk M. <dmu...@ho...>]

Thanks. Well, while it is really good for running code whithout the pain of installation, it doesn't really seem to be made for source code distribution.

The core 0install tools have now also moved there. This should make it
easier for other people to make releases, since the new repository
uses GitHub actions to publish, rather than requiring access to my GPG
key. I've signed Bastian's update to the old repository, making the
old feeds redirect to the new location
(https://github.com/0install/0install-feeds/pull/8).

[Zero-install-devel] Zero Install for Windows 2.18 released

[Bastian E. <ba...@ei...>]

Zero Install for Windows 2.18 has been released. This improves context menu
desktop integration (icons, cascading menus, directory background menus) and
archive extraction (support for .tar.lz, .tar.zst and .rar).

Download: https://get.0install.net/#windows

## Changes

### Desktop integration

- Added context menu icons
- Added support for cascading context menus (see
https://docs.0install.net/specifications/capabilities/#context-menu-entries)
- Added entries to directory background menus
- Added support for <arg>s in <verb>s (see
https://docs.0install.net/specifications/capabilities/#verbs)
- Improved icon caching

### Archive extraction

- Added support for extracting `.tar.lz`, `.tar.zst` and `.rar` archives
- Improved performance when extracting `.tar.lzma`, `.tar.xz` and `.7z`
archives

### Misc

- Improved support for Sync with local/network filesystem (see
https://docs.0install.net/details/sync/)
- Added support for detecting .NET Framework 4.8

[Zero-install-devel] 0install 2.17

[Thomas L. <ta...@gm...>]

0install 2.17 is now available (source and generic binaries):

  https://docs.0install.net/details/linux/#from-source
  https://0install.net/injector.html#linux-generic

I'm now putting the source release on GitHub rather than sf.net, and
so there are some release notes there:

https://github.com/0install/0install/releases/tag/v2.17

The main new thing is that the solver has a public (OCaml) API and its
own opam package (0install-solver), allowing other package managers to
use the same solver engine. I've been using this to speed up opam
itself: https://github.com/talex5/opam-0install-solver

opam packages tend to have more dependencies than 0install ones, and
the diagnostic output was rather verbose, so I've added some logic to
filter out constraints that didn't affect anything. This makes the
reports easier to read for 0install packages too! e.g. see the example
in https://github.com/0install/0install/pull/158

[Thomas L. <ta...@gm...>]

0install 2.15.2 and 2.16 are now available (source and generic binaries):

  https://docs.0install.net/details/linux/#from-source
  https://0install.net/injector.html#linux-generic

I'm now putting the source release on GitHub rather than sf.net, and

https://github.com/0install/0install/releases/tag/v2.15.2
https://github.com/0install/0install/releases/tag/v2.16

You can subscribe to get just release announcements by choosing "Watch
-> Releases only" using the button at the top.

But the main change is:

- 2.15.2 splits out the GTK gui into a separate 0install-gtk opam
package (so "opam install 0install-gtk" if you want it).
- 2.16 updates it from GTK2 to GTK3

[Zero-install-devel] Python 3 releases of various tools

[Thomas L. <ta...@gm...>]

I've made new releases of various tools to complete the Python 3
transition. Here are the combined release notes:

0install (old Python branch):

2.3.7:

- Update to new apps.0install.net URIs.

- Add may_compile to Requirements slots. This avoids an error if we
try to use the Python 0install library to read a requirements file
generated by the OCaml version of 0install. Error was: AttributeError:
'Requirements' object has no attribute 'may_compile'

- Windows needs gobject too. See: https://github.com/0install/0compile/issues/4

- Switch from tulip mainloop to asyncio. This is used when
glib/gobject isn't available. Tulip was an experimental library, but
Python 3.7's asyncio seems almost identical.

- Rename "async" to "aasync" for Python 3.7. "async" is a keyboard in
Python 3.7, making the old code a syntax error. When running on Python
< 3.7, the old "async" is still available as an alias.

2.3.8:

- Require Python >= 3.4 and drop gobject requirement.

2.3.9:

- Fix import error on Python 3.5 and 3.6.

2.3.10:

- Fix occasional crash when downloading in Python 3. Error was:
TypeError: '<' not supported between instances of 'Download' and
'Download'

- Update for new PackageKit API.

- Explicitly depend on pywin32 on Windows.


0publish 0.26 (https://docs.0install.net/tools/0publish/):

- Migrate to Python 3.

- Add Travis tests.

- Replace repo.roscidus.com feeds with apps.0install.net (Bastian Eicher).

- Fix digest generation. We previously called hexdigest to get the
digest, but the newer algorithms use base32. Use the proper helper
method to get the right format.


0test 0.10 (https://docs.0install.net/tools/0test/):

- Allow passing an app name as the first argument. If no versions are
specified, we test the versions currently used by the app. Otherwise,
we just get the URI from the app but select our own versions.

- Convert to Python 3.

- Add Travis tests.

- Update from old repo.roscidus.com names.


0compile 1.7 (https://docs.0install.net/tools/0compile/):

- Migrate to Python 3.

- Use aasync instead of async for Python 3.7 compatibility.

- Remove gobject.threads_init. Not needed on newer versions and we
import support.tasks, which will do it for us anyway if needed.

- Replace repo.roscidus.com feeds with apps.0install.net (Bastian Eicher).


0release 0.17 (https://docs.0install.net/tools/0release/):

- Migrate to Python 3.

- Add .coveragerc to measure 0release's test suite.

- Replace repo.roscidus.com feeds with apps.0install.net (Bastian Eicher).


0repo 0.11 (https://docs.0install.net/tools/0repo/):

- Migrate to Python 3.

- Add upgrade instructions.

- Migrate test GPG keys to new format.

- Replace repo.roscidus.com feeds with apps.0install.net (Bastian Eicher).

[Zero-install-devel] 0install 2.15.1

[Thomas L. <ta...@gm...>]

0install 2.15.1 is now available (source and generic binaries):

  https://docs.0install.net/details/linux/#from-source
  https://0install.net/injector.html#linux-generic

Since 2.15:

Changes

- Replace repo.roscidus.com feeds with apps.0install.net (Bastian Eicher).

- Update fallback host-Python check for new URIs.
  http://repo.roscidus.com/python/python is now
https://apps.0install.net/python/python.xml, etc.

Bug fixes

- Fix use of nested Lwt_main.run. This is now an error with Lwt 5.0.0.

- Fix bad error message when running as root with invalid $HOME. If
we're running as root then we check that $HOME is owned by root to
avoid putting root-owned files in a user's home directory. However, if
$HOME doesn't exist then the error Unix.ENOENT was unhelpful.

- Fix bad solver error. The diagnostics system didn't consider
dependencies of <command> elements when trying to explain why a solve
failed. It could therefore report "Reason for rejection unknown" if a
solve failed due to a constraint inside one.

- When using --may-compile on a local selection, set local-path. We
already gave the full path in local-path for other selections, and
without this an exception is thrown if we try to print the resulting
tree.

Build system

- Move windows C code to its own library. This allows us to use the
new (enabled_if ...) feature to enable it only on Windows, simplifying
the dune files and avoiding the need for cppo.

- Get the windows_api object via the system object, rather than making
it a special case.

- Remove windows-specific flags from utils.c. Looks like these were
left over from when there was more code here.

(Windows changes are untested, but pass CI)

[Zero-install-devel] Python 3 migration status

[Thomas L. <ta...@gm...>]

Python 2 is reaching end-of-life soon, and it seems that some
distributions are starting to remove it already. I'm in the process of
migrating the remaining Python tools. Unfortunately, the 2to3
conversion tool doesn't catch everything, and neither do the
unit-tests. I'm making new "testing" releases when things seem
reasonably stable, but please report crashes when you see them (or
stick to the "stable" releases).

The main 0install tool is now written in OCaml and is therefore
unaffected, but many of the Python tools still use the old Python
version of 0install. We added Python 3 support to that back in 2012,
but I'm still finding new bugs. I've released 2.3.7, 2.3.8, 2.3.9 and
2.3.10 over the last few days, with increasingly less crashy
behaviour.

I've also made new Python 3 releases of 0publish and 0test, and I'm
hoping to get 0repo and 0release done too soon. 0compile is done,
except for the GUI. That might take a while, as testing the GUI parts
is difficult. Maybe I should just remove the GUI.

[Zero-install-devel] Fwd: Request 762101 created by scarabeus_iv (delete openSUSE:Factory/zeroinstall-injector)

[Thomas L. <ta...@gm...>]

I just got this email. Does anyone here use openSUSE? Looks like the
package there could do with being updated. Any volunteers?

I don't remember how openSUSE packaging works any more, but there's a
page at https://build.opensuse.org/project/show/devel:languages:ocaml
which seems to have all the dependencies we need, except obus. Not
sure if that means they're available for openSUSE packages to use,
though. I'm not sure what their official policy on vendoring is, but
if it's allowed then you can just drop the source for e.g. obus
somewhere under 0install's own source directory and it will find it
and build against it automatically.

[Zero-install-devel] Announcing apps.0install.net

[Bastian E. <ba...@ei...>]

https://apps.0install.net/ provides Zero Install feeds for common tools,
libraries and runtime environments. It replaces http://repo.roscidus.com/,
which is now deprecated.

The new feed URIs start with https://apps.0install.net/ and end with .xml.
The old feeds at http://repo.roscidus.com/ remain valid and simply redirect
to the new feeds with <feed> and <replaced-by> tags.

The feeds at apps.0install.net are signed with a new GPG key with the
fingerprint 88C8A1F375928691D7365C0259AA3927C24E4E1E.

We also used this opportunity to make some more changes to URIs:
- Shortened some names, such as python/pygtk.xml instead of
python/python-gtk.xml. 
- Merged a number of directories. For example the contents of "security",
"google", "hashicorp" are now in "utils".
- Created a new directory "gui" for apps like LibreOffice and Notepad++.

The following feeds were excluded from the move to apps.0install.net because
they are no longer maintained:
http://repo.roscidus.com/java/openjdk-6-jdk
http://repo.roscidus.com/java/openjdk-6-jre
http://repo.roscidus.com/e/e-core
http://repo.roscidus.com/e/e-swt
http://repo.roscidus.com/drupal/core
http://repo.roscidus.com/drupal/smtp
http://repo.roscidus.com/google/cloudsql-proxy
http://repo.roscidus.com/games/openttd
They will remain available unchanged at http://repo.roscidus.com/. Please
let us know if you are still using any of these feeds.

Re: [Zero-install-devel] Feed for a Vim plugin?

[Bastian E. <ba...@ei...>]

> 1. Is there a way to find out from command-line which version of a particular "implementation" of a specific "interface" is currently installed?

Note that with Zero Install there is not really a concept of something being "installed". Rather an implementation is "selected" by the dependency solver and then downloaded/cached to be run.

0install select http://example.com/feed.xml
shows the version/implementation (including potential dependencies in a tree-like view) that would be used by "0install run".

0install select --xml http://example.com/feed.xml
gives you a machine-readable version of this output.

0install store list-implementations http://example.com/feed.xml
lists all version/implementations that are currently in the cache from previous runs of "0install download" or "0install run". It does not show dependencies.


> 2. For Vim, I'd like to be able to have it available on Windows in an "Open with" context menu *for all file types*, while not being the "default handler" for any file types. Do 0install desktop integrations allow for such a variation?

If a feed lists <file-type>s and you perform desktop integration with Zero Install for Window (either using the GUI or the "0install integrate" command) that is exactly what you get. Zero Install registers the feed/app as an "Open with" candidate for the specified file types. It leaves setting the default handler up to the Windows GUI. As a matter of fact, starting with Windows 8 the OS actively prevents third-party applications from changing a file type's default handler.
