How To Publish Binary PackagesΒΆ

First, publish a source package by following the tutorial for how to publish a source package.

Test that you can successfully build from source.

0compile -c setup http://zeroinstall.dasgizmo.net/snappy.xml
cd snappy
0compile -c setup
0compile build

Create the binary package to be uploaded to the server and the xml snippet to add to the feed.

0compile publish http://zeroinstall.dasgizmo.net/archives

Copy the tarball to the server

  cp snappy-linux-x86_64-1.1.0.tar.bz2 /var/www/zeroinstall/archives/

Next we need to update the repository feed file to include the new implementation.

Copy the "implementation" portion from the ``snappy-1.1.0.xml`` created when you ran the ``0compile publish`` command.

<group arch="Linux-x86_64">
  <implementation id="sha1new=06c387ae0fafc56bf4d682dd8a7d7f4e49d6d274" released="2013-08-07" version="1.1.0">
    <manifest-digest sha256new="VNEAOHELYHO74ZB4GGYLVK6PDHLGN46WODKEC5RSQAF2HZP23HFQ"/>
    <archive extract="snappy-linux-x86_64-1.1.0" href="http://zeroinstall.dasgizmo.net/archives/snappy-linux-x86_64-1.1.0.tar.bz2" size="140408"/>
  </implementation>
</group>

Next paste this snippet into the snappy.xml feed in the feeds directory of your 0repo server (this assumes you followed the previous tutorial and a source feed already exists).

cd $HOME/repo/feeds
vim snappy.xml
# now paste the snippet you copied above so the file looks like this

 <?xml version="1.0" ?>
 <interface uri="http://zeroinstall.dasgizmo.net/snappy.xml" xmlns="http://zero-install.sourceforge.net/2004/injector/interface">
<name>snappy</name>
<summary>A fast compressor/decompressor</summary>
<description>
 Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger. On a single core of a Core i7 processor in 64-bit mode, Snappy compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec or more.

Next tell 0repo you modified the feed by committing the changes to the internal git repository.

git commit -a

Next tell 0repo to update the catalog

cd $HOME/repo
0repo update

Now if you check the feed url, you’ll see the source AND binary packages.
