PPA for Travis

[automata]

Is there any PPA available for Travis building instead the preinstall script?

[lovell]

Hi Vilson, I'm not aware of a PPA for Ubuntu 12.04 as used Travis.

Amongst many other packages, https://launchpad.net/~dhor/+archive/ubuntu/myway provides a pre-compiled libvips-dev and dependencies for 14.04 and 14.10.

If you know of one or would be willing to maintain one, I'd be very happy to use it :)

+1 for being able to install sharp on Travis CI’s new sudo-less container infrastructure: http://docs.travis-ci.com/user/workers/container-based-infrastructure/ Unfortunately, preinstall.sh currently requires sudo. We were forced to use the new infrastructure due to some other dependency (Sauce Connect) not working well on the old Travis infrastructure but I will give it another shot. Is there a way to make preinstall.sh work without sudo?

[lovell]

@gasi I believe PPAs require sudo access so this probably won't help you.

#42 is the best place to discuss non-root installation of libvips and #186 is the most tempting solution I've seen so far.

[gasi]

Small update: We’ve opted back into sudo: required on Travis and preinstall.sh works. However, all dependencies are installed via apt-get but libvips itself is compiled from source which unfortunately adds several minutes to our build process. When I add the following for Travis’ Debian Precise:

        precise|wheezy|maya)
          # Debian 7, Ubuntu 12.04, Mint 13

          # ...

          echo "Installing libvips via apt-get"
          apt-get install -y libvips-dev libgsf-1-dev

it seems to install libvips successfully but sharp’s build process fails with the message:

Package vips was not found in the pkg-config search path.
Perhaps you should add the directory containing `vips.pc'
to the PKG_CONFIG_PATH environment variable
No package 'vips' found

Any suggestions on how to install via apt-get on Travis to avoid long compilation time?

[lovell]

I still believe #186 provides the best (potential) solution to avoid users having to compile dependencies and allow sudo-less installation.

[lovell]

For Ubuntu 12.04, a pre-compiled v7.40.6 of the libvips-dev package and friends are now available via:

sudo add-apt-repository ppa:lovell/precise-backport-vips

...and for Ubuntu 14.04:

sudo add-apt-repository ppa:lovell/trusty-backport-vips

This is the most recent version of vips that I can get to package correctly (dependencies etc.)

I can't use this PPA for sharp itself as the functional tests require v7.42.0+.

@lovell This is great — I just tested it and it works! 👍

For anyone else, who needs VIPS on Travis, ensure the following in .travis.yml:

1. Enable sudo: required

2. Optional:

     # Suggested setting for `apt`:
     # http://docs.travis-ci.com/user/caching/#Caching-Ubuntu-packages
     cache: apt
   

3. Install VIPS using PPA:

     before_install:
       - echo "Installing libvips..."
       - sudo add-apt-repository -y ppa:lovell/precise-backport-vips
       - sudo apt-get update
       - sudo apt-get install -y libvips-dev
       - echo "Completed libvips installation."
   

@lovell In order to use Travis’ more modern container-based infrastructure (using Docker), we’d need to add your PPA to this whitelist: https://github.com/travis-ci/apt-package-whitelist

See: http://docs.travis-ci.com/user/migrating-from-legacy/#How-do-I-install-APT-sources-and-packages%3F

Want me to do it or would you like to?

[lovell]

@gasi If you're a paying customer of Travis then it makes sense for you to make this request. I can see one other PPA in the "whitelist", namely libssl-dev/lucid, so I guess its inclusion should be OK.

[gasi]

@lovell Thanks, I submitted it as travis-ci/travis-ci#4398. In the meantime, I learned that one can compile from source and then cache that:

• http://docs.travis-ci.com/user/migrating-from-legacy/#How-Do-I-Install-Custom-Software%3F
• http://docs.travis-ci.com/user/migrating-from-legacy/#How-Do-I-Cache-Dependencies-and-Directories%3F

I don’t have time to explore that at this point but if anyone wants to, this could get us back onto Travis’ container infrastructure (sudo: false).

[raphaelokon]

Are there any news on this topic? The sudo preinstall.sh is blocking our deployment from being moved to the newer Travis container infrastructure.

Thanks.

[lovell]

@nordisk I notice you've found and commented on travis-ci/apt-source-safelist#68 :)

[raphaelokon]

Aye. Still not sure how to proceed on this one tho :)

[lovell]

travis-ci/apt-source-safelist#137

[lovell]

(@nordisk Not sure if he told you but @nicklester and I worked together a few years' ago.)

[raphaelokon]

@lovell He told me that actually after I used sharp for one of our tools and he saw you as the author :)

[lovell]

If you've not already seen it, please subscribe to #42 for updates about the forthcoming dependency-less installation of sharp. This will allow for sudo-less operation on Travis CI e.g. https://travis-ci.org/lovell/sharp/jobs/87978123

[lovell]

Last call for comments on #42.

[lovell]

I'll be closing this question soon as v0.12.0 (and the current master branch) no longer require root/sudo access on 64-bit Linux, which includes Travis.

[raphaelokon]

Cheers!

[lovell]

v0.12.0 now available via npm

[raphaelokon]

Aces! thanks for the great work @lovell
