[Vtigercrm-developers] Let's make 7.4 fruitful

[Martin Allen]

   - Package dependencies are managed within composer itself e.g. Pear DB
   package is available in Composer (yes I know it's been superseded already
   by MDB2 but its an example) and is dependent on other Pear packages, except
   as developers we don't need to worry about those other dependencies as they
   are automatically handled.
   - Package updates can be handled very simply without the need to
   download the entire CRM again, so if a security issue is identified in for
   example Pear DB, in a couple of minutes it can be updated (in a
   non-breaking fashion because all packages adhere to semantic version
   numbering) - problem solved.
   - As Alan mentioned the autoload.php, which on a production environment
   is optimized for increased speed.
   - Using PSR-4 Namespaces and the autoload.php makes packages available
   application wide simply with the 'use' namespace syntax. (How many times
   have you gotten frustrated because include statements don't work as
   intended!)

Yes there would be some complications around custom modules requiring other
dependencies - I believe there are ways of calling composer to run composer
commands as part of an installation script - this would need some further
investigation though.

One of the biggest questions that needs to be answered is the intended
audience for vTiger CRM going forward. Is it going to be designed for
simple one-click install applications that anyone can download, or is it
intended for technical/developer types who know/understand how to manage
Composer installs / updates?
It would be possible to use Composer as part of the development process and
then include the /vendor contents and everything else required inside the
single ZIP download still. This would allow those who do not understand /
have access to Composer to get SOME of the benefits but for those that do
have access/knowledge can get ALL the benefits ?
