Hi,

Reminder:

* PHP 5.5 have zip extension 1.11.x and bundles libzip version 0.10
* PHP 5.6 have zip extension 1.12.x and bundles libzip version 0.11
* PHP 7.x have zip extension 1.13.x and bundles libzip version 1.1.2
* PHP master have zip extension 1.14.x

We also maintain the pecl extension, mostly for downstrean (linux
distribution) which prefer to manage this extension according to system
libzip version, rather than using the bundled version.

Ex (in Fedora)
*  F20, PHP 5.5, libzip 0.11, zip 1.12
*  F21, PHP 5.6, libzip 0.11, zip 1.12
*  F23, PHP 5.6, libzip 1.1   zip 1.13
*  F25, PHP 7.0, libzip 1.1,  zip 1.13
*  F26, PHP 7.1, libzip 1.2,  zip 1.14

The pecl extension is also used for new features development.

Today, we have released zip extension 1.14.0 with encryption support
from libzip 1.2.0.

The new version also drop support of bundled libzip, and only supports
build with system library as doesn't make sense to keep the bundled
copy, as maintained for downstream which prefer system lib.

Notices:

- PHP master have zip 1.14 but with bundled libzip 1.1.2
  (so some new features are missing)

- PHP master support system libzip on Linux and Windows
  (thanks to Anatol)

- We dont carry any patch in bundled libzip (since 5.5)

- We support all libzip versions >=3D 0.11

- Updating bundled libzip is always a huge and messy job



DISCUSSION:

I think it is time to drop the bundled libzip from PHP master and only
support the use of the system library, as for most of libraries PHP uses
(openssl, libz, libbz2, curl...)


Comments ?



Remi

P.S. if needed, I can write a quick RFC
