👍 I almost made the same change in other PR and I was testing it irght now (https://github.com/javiereguiluz/symfony-demo/commit/bf799e4308035e7e07883e58d0628f6ea76c22b3) Thanks!

[bocharsky-bw]

Oh, now I see. :)

[bocharsky-bw]

I think I could close this PR

[javiereguiluz]

Let's wait a bit ... neither your PR nor mine work at the moment :)

@javiereguiluz The problem was I forgot to update composer.lock via $ composer update

[javiereguiluz]

@bocharsky-bw true! Should we remove the composer.lock file? In Travis the old problems with PHP 5.3 are gone, but now we have new problemas with 5.6 😠

[bocharsky-bw]

No, composer.lock file should be in the repo for same environment for all developers who use this repo.

The problem is we should always update dependencies when change composer.json file via command $ composer update. This command generate new composer.lock file with a new dependencies from changed composer.json.

Let's ask for help to our friends @stof and @xabbuh to see if they can tweak the composer.json dependencies to fix Travis issues. Thanks!

[stof]

The symfony-demo is a project, so we should indeed commit the lock file. See 0fd26c6#commitcomment-12339685 for the solution

[javiereguiluz]

@stof thanks a lot for your help and for the explanation!!

@bocharsky-bw please add the following in composer.json:

"config": {
        "platform": {
            "php": "5.3"
        }
    },

Besides, we can remove the doctrine/dbal dependency and we can simplify doctrine/orm to ~2.4.

[bocharsky-bw]

I had next error for "platform": { "php": "5.3" } when did $ composer up:

  Problem 2
    - symfony/symfony v2.7.2 requires php >=5.3.9 -> your PHP version (5.6.4-4ubuntu6.2) does not satisfy that requirement.
    - symfony/symfony v2.7.2 requires php >=5.3.9 -> your PHP version (5.6.4-4ubuntu6.2) does not satisfy that requirement.
    - symfony/symfony v2.7.1 requires php >=5.3.9 -> your PHP version (5.6.4-4ubuntu6.2) does not satisfy that requirement.
    - symfony/symfony v2.7.0 requires php >=5.3.9 -> your PHP version (5.6.4-4ubuntu6.2) does not satisfy that requirement.
    - Installation request for symfony/symfony ~2.7 -> satisfiable by symfony/symfony[v2.7.0, v2.7.1, v2.7.2].

so I bumped platform PHP version to 5.3.9, it's ok?

[stof]

@bocharsky-bw yes (and we should change the min version in the symfony-demo composer.json too)

[bocharsky-bw]

Still failed

[bocharsky-bw]

Looks like old version of Composer on Travis machine was a problem :(

[bocharsky-bw]

@stof Thanks for your help!

[javiereguiluz]

@bocharsky-bw great!!! We finally have green Travis results! Thank you! 🎉 🎉 🎉
