Description:
------------
imagick should use PHP's default temp. directory. Since PHP 5.5 there's also a sys_temp_dir ini-directive the admin can define.

Change is simple:

Does this override MAGICK_TMP_PATH environment variable?

[2013-11-07 14:48 UTC] manuel-php at mausz dot at

Yes, looks like it does: http://www.imagemagick.org/api/MagickCore/resource_8c_source.html#l00376

Maybe we should only do this if MAGICK_TEMPORARY_PATH & MAGICK_TMPDIR is *not* set?

[2013-11-07 15:05 UTC] mkoppanen@php.net

This would be unexpected for users who expect the files to be stored into TMPDIR if other env variables are not set.

While this is a sensible idea this has to wait until next major version.

[2013-11-07 15:12 UTC] manuel-php at mausz dot at

TMPDIR-users won't be affected unless they use PHP >=5.5 and set sys_temp_dir + TMPDIR to different values. Doubt that there's a even single user using such configuration.

php_get_temporary_directory returns INI(sys_temp_dir) OR ENV[TMPDIR] OR P_tmpdir, whichever comes first.

[2013-11-07 15:23 UTC] mkoppanen@php.net

Other scenario where this seems problematic are cases when user calls putenv runtime and expects that to change the temporary directory. Not sure how common this is.

[2013-11-07 15:36 UTC] manuel-php at mausz dot at

Yes, that's another scenario.

However I'm perfectly fine with adding this change to your next major release.

Although the functionality to set the temp path, it shouldn't be in the ini file. Instead we should expose it through functions. I think we need:

Imagick::setRegistry calls SetImageRegistry
Imagick::getRegistry calls GetImageRegistry
Imagick::listRegistry returns an array of all the key pairs in the registry through GetNextImageRegistry() and GetImageRegistry

This was implemented in Imagick 3.3.0RC1
