client downloads latest dev release of composer.phar

[fritzmg]

When using composer 1.6.0 (which was released today) the following error occurs:

The composer client is downloading the latest dev release of the composer.phar instead of the latest stable release (see below) which led to the following problem:

Fatal error: Uncaught exception Error with message Class 'Composer\Factory' not found thrown in system\modules\!composer\src\ClientBackend.php on line 294

#0 system\modules\!composer\src\ClientBackend.php(125): ContaoCommunityAlliance\Contao\Composer\ClientBackend->loadComposer()

I have hat the same problem but deleting the composer.phar and all backup copies in TL_ROOT/composer/ and re-downloading composer.phar fixed it for me.

I suppose the download was somehow corrupted.

Actually I was mistaken. The composer-client didn't download 1.6.0 (stable). It is downloading 1.7-dev:

Composer version 1.7-dev (749b4c46b74f9702fc4f6abde6480fb6f0373ed6) 2018-01-04 11:22:11

Today, it is downloading the following version:

Composer version 1.7-dev (be040f8e3111b38c1e49ae5cd6b929dbf5c39045) 2018-01-05 07:41:58

which probably re-added the Composer\Factory.

So the actual problem is that the composer-client isn't downloading the latest stable release. Didn't we have this problem already?

We did long time ago, we added the "do not update composer.phar" option back then.

The problem is/was, that there is no "latest stable URL" and nobody ever implemented the list downloading and lookup of the latest phar to download.

There is now: https://getcomposer.org/composer-stable.phar
