T15326: PHP 8.0 without GD installed: Unhandled Exception setting a project profile image: Call to undefined function imagecreatefromstring()

Commits

rP7a86040f8a46: Avoid exception setting project profile image when GD not installed

Summary

When trying to set a custom project profile image while the PHP GD extension is not installed, use the same logic which already exists in PhabricatorFilesComposeAvatarBuiltinFile.php to set the default project image. This stills display an unhelpful error message This server only supports these image formats: . but avoids an exception trying to call GD's imagecreatefromstring().

EXCEPTION: (Error) Call to undefined function imagecreatefromstring() at [<phorge>/src/applications/files/builtin/PhabricatorFilesComposeIconBuiltinFile.php:131]

Closes T15326

Test Plan

Remove the php-gd (and potentially gd) packages on your system; restart httpd
Go to http://phorge.localhost/project/manage/1/
Select Edit Picture in the sidebar on the right to go to the Edit Project Picture at http://phorge.localhost/project/picture/1/
Set a custom icon and color and click the Save Image button
Get This server only supports these image formats: . but no exception anymore

Do we have a setup-warning about the gd extension being missing?

@avivey: In theory yes in https://we.phorge.it/source/phorge/browse/master/src/applications/config/check/PhabricatorGDSetupCheck.php .
In practice I have no idea how to trigger it (or how/when these setup checks are performed) for an existing Phorge instance that I'm not about to freshly set up.

I wonder if it then, upon deletion of the profile image, it attempts to delete the builtin image

How to delete a profile image? Steps welcome so I could test.

I was able to trigger the "missing gd" warning (By uninstalling php*gd), so we're good there.
A bit puzzled about how you got the error if you already have it installed?

The only way to delete things is using ./bin/remove destroy Fxxx from the command line.
For built-ins, I think it might attempt to delete them (They have an File object), and then they will be re-created automatically by something.

@valerio.bozzolan How is attempting to delete a built-in (!) profile image related to this patch? If I misunderstood, please elaborate. Thanks!

Sorry, should have been more verbose. I uninstalled both php-gd and gd on a Fedora 39 system to trigger this. (Somehow also the latter was needed, the former didn't suffice.)

AFAIK the method composeImage() was supposed to create something new (so, probably writable and deletable). Now instead it can return something that is supposed to be read-only.

I also can't think of a way to delete a profile picture either, so probably my note means nothing.

(By the way the Filesystem::readFile() does not return a pointer to a (potentially read-only) resource, but it just returns its content - so the concern was nonsense)
