It seems to be that on the plugin methods we are returning True to signal that everything went well.
I think it will be better to return nothing in case of success, or the artifact generated in case it's needed for other steps.
In case of error, we raise an exception.

Alan put together a branch which builds lp:music-app using the cmake plugin (https://bazaar.launchpad.net/~popey/+junk/music-app-snap/view/head:/snapcraft.yaml). This works just fine, but a lot of dependencies are not bundled, so I tried to use the qml plugin. This works fine, but the music-app expects some files in the right place (like translations), for which it uses cmake.

Trying to use both (snapcraft.yaml snippet below), you run into the problem that both try to install the same files (the qml plugin installs * - https://bazaar.launchpad.net/~snappy-dev/snapcraft/core/view/head:/snapcraft/plugins/qml.py#L67), which breaks the build. Maybe the qml plugin could be more selective in what exactly it tries to bundle?

i.e. the following would work:
parts:

Hi,

While testing ant and jdk plugins, I noticed a couple of things; this bug to discuss the best resolution.

First, I was surprized by a "jdk" plugin; I actually thought the plugin would be "jre" because I thought it was just embedding a java runtime. But then I noticed that "ant" wasn't working on my system, compilation would fail with missing javac classes. This is because the ant Ubuntu package doesn't pull a JDK but only a JRE. Yet, ant was run successfully during a snapcraft build. This is because ant was being run with the java runtime pulled by the jdk plugin (from the snap).

I found this surprizing, I was actually expecting the ant package would be used on my system against the java runtime on my system, but I can see how there are pros and cons to using system java vs. snap's java.

Pros of using system jdk to run ant and embedding a jre package in the snap:

• smaller runtime -- the current approach still ends up embedding a bunch of lib_.a files, lib_.so (including X.org libs)
• feels more natural (to me)
  Cons:
• ant doesn't pull a jdk by default
• more complex to digest (more plugins)

Pros of using snap's jdk to run ant:

• less copies of java around -- no discrepancies, perhaps less waster space (not sure)
• less plugins

To make the matter more complex, I believe we should have multiple architecture in mind. This problem will get worse when we're considering building packages across architectures and/or for multiple architectures. This is actually quite common in the "develop on x86-64 Ubuntu desktop, deploy on ARM board" scenario.

This last topic is actually what convinces me we should go for using the system JDK to run ant rather than the snap's JDK. This makes the snap less easily bloated with JDK bits (we could offer regular vs. -headless jre as an option to make this even smaller), and
means we dont need to worry about cross-architecture. It's even relatively easy to support multiple architectures if we stop relying on default-java and rather use java-7-openjdk-amd64 and such.

(BTW, we seem to pull Recommends; it's not clear whether it's a good default given these are usually not pulled when building .deb packages)

Hence, I propose we:

• change the ant plugin to pull the default-jdk package (on top of the ant package) -- this kind of feels like a workaround for the package not pulling the jdk by default which is either a bug or just a packaging opinion that "ant can be used for anything, not necessarily building java sources"
• rename the jdk plugin to jre -- possibly ubuntu-jre or openjdk-jre, allowing for oracle-jre and similar, but I find the long names look ugly
  (- add an option to select the headless JRE)
• differentiate between build and runtime envs

But happy to read other opinions!

Cheers,

For some non-trivial projects, a snapcraft part developer might like to ship a makefile in the source tree of the snap without having to modify an existing source tarball of a 3rd party project. For that use case, the developer could use the optional "makefile" part attribute to override the makefile executed by snapcraft to build that given part.

For example:

parts:
foo:
type: makefile
makefile: Makefile.foo

This would cause snapcraft to run the following command at part build time:

make -f Makefile.foo -C parts/foo/build

building a package on launchpad where the environment is set to --no-install-recommends results in a completely different build result vs doing a local build at home.

snapcraft should make sure to override --no-install-recommends or it should enforce its usage for local build, i think either way is fine as long as we achieve consistency ...

I am running snapcraft assemble (qml plugin) on ted's branch lp:~ted/+junk/digitalsign

while iterating over the package, I added 1 new file in ./pic.jpg and edited snapcraft.yaml accordingly:

digitalsign:
plugin: copy
mkdirs:

files:
digitalsign: bin/digitalsign
digitalsign.qml: digitalsign.qml
pic.jpg: pic.jpg

rerunning snapcraft assemble will not pull in the new file, as it's skipping the build stage:

olli@joe-XPS-12-9Q33:~/code/snappy/digitalsign$ ../../qml/bin/snapcraft assemble
Skipping pull digitalsign (already ran)
Skipping build digitalsign (already ran)

...

upon deleting ./snap/ ./parts/ ./stage/ the file is being pulled in:
...
Building digitalsign
cp --preserve=all -R digitalsign /home/olli/code/snappy/digitalsign/parts/digitalsign/install/bin/digitalsign

cp --preserve=all -R pic.jpg /home/olli/code/snappy/digitalsign/parts/digitalsign/install/pic.jpg
...

while not critical (workaround: delete files, start over) it's imho a bad experience as it can be expected that developers will iterate over the package quite frequently, rebuilding is taking longer time and thus not desirable

Hi,

LD_LIBRARY_PATH currently includes triplet as computed at snap creation time, but it should rather be set at runtime on a per-architecture basis.

In fact, a better approach would be to set a RPATH relative to the binary: $ORIGIN/../../lib/$PLATFORM, or something like that.

I was trying out snapcraft current head and found that it is not the tool i can use at the moment, as i cannot compile everything quickly on the target architecture in a clean environment.

For debian packages we use a combination of cowbuilder, cowdancer and pbuilder to provide clean repeatable build environment on the various target environments.

It should be evaluated how building of snaps can be integrated with gear like that so it is possible to build snaps with similar gear. Ultimatively something like "ARCH=armhf snapcraft --cowbuilder ..." should produce snaps using the defined environment.

This method of string formatting is the new standard in Python 3, and should be preferred to the % formatting described in String Formatting Operations in new code.

At the moment the python3 plugin obliges you to pass a file with requirements. It would be easier to list all the requirements so in addition to a file like this:

plugin: python3-project
requirements: file-with-requirements

this would be great:
plugin: python3-project
requirements:
- requirement1
- requirement2

Old school way to do things, we should have an option to use the slick new autoreconf tool.

Trying out snapcraft, starting with a very simple project. I wrote a very simple Python service:

import time

i = 0

while i < 1000:
print("this is a python snap: " + str(i))
i += 1
time.sleep(5)

I wrote the following snpacraft.yaml:

name: python-snap
version: 1
vendor: Rick Spencer
summary: a test of snapcraft
description: a longer test of snapcraft

parts:
loop:
type: python3-project

I ran $snapcraft stage

and got this error:

Consistency is important, specially in the python world :)

So we should stick with only one form of string literals. Most of the canonical projects prefer single quotes.

So instead of "hello", use 'hello'

The internal run command in snapcraft/common.py doesn't support arguments with spaces. It needs to either escape its arguments for the benefit of the shell it runs under or run the command a different way.

The help subcommand should provide help for specific snapcraft topics and plugins.

This is a feature request:

The MQTT Paho client is doing lots of things and extensive testing when you use the default maven plugin. The documentation recommends to use:
mvn package -DskipTests

But in the maven plugin there is no option to specify package and -DskipTests

So something like

javamqtt:
plugin: maven-project
mvnoptions: package -D skipTests
source: git://git.eclipse.org/gitroot/paho/org.eclipse.paho.mqtt.java.git

Ubuntu plugin: allow downloading of binary packages from PPAs.

It'd be great if I could specify "for part X I need package Y from PPA Z". Concrete example:

ubuntu-docviewer-app soon will need bits from a special armhf build of libreoffice (https://launchpad.net/~canonical-community/+archive/ubuntu/ppa).
