Inform Rainloop-nc users of Snappymail variant better maintained

[pierre-alain-b]

The work here is progressing very nicely: the-djmaze/snappymail#96

@the-djmaze when you think there is a viable and stable snappymail plugin for NC, I propose to release a final rainloop-nextcloud version where the name of the plugin is changed to "Rainloop (deprecated), consider migrating to Snappymail" with a link to the new NC plugin.

What do you think?

@pierre-alain-b this is great news.
looking very forward to snappymail.
please allow simple automated migration, especially for Nextcloud-snap users where direct access to "data" is complicated.

[pierre-alain-b]

That's a very good comment!

@the-djmaze, I've tried to just move the rainloop_storage folder as an appdata_snappymail with no success... Do you have a clue on what was changed between the local storage of Rainloop and snappymail? Is there a way we could make the migration easy in your mind?

[the-djmaze]

You or SnappyMail might could do this:

$dir = \rtrim(\trim(\OC::$server->getSystemConfig()->getValue('datadirectory', '')), '\\/').'/appdata_snappymail/';
if (!\is_dir($dir)) {
	\mkdir($dir);
	$rainloop = \dirname($this->appManager->getAppPath('snappymail')) . '/rainloop/app/data';
	$rainloop = $this->appManager->getAppPath('rainloop')) . '/app/data';
	if (\is_dir($rainloop)) {
		$iterator = new \RecursiveIteratorIterator(
			new \RecursiveDirectoryIterator($rainloop, \RecursiveDirectoryIterator::SKIP_DOTS),
			\RecursiveIteratorIterator::SELF_FIRST
		);
		foreach ($iterator as $item) {
			if ($item->isDir()) {
				\mkdir($dir . DIRECTORY_SEPARATOR . $iterator->getSubPathname());
			} else {
				\copy($item, $dir . DIRECTORY_SEPARATOR . $iterator->getSubPathname());
			}
		}
	}
}

Basically the idea is "just" to copy the file tree of rainloop into snappymail or is there anything to tweak?

[the-djmaze]

just copy does not work.

1. plugins are incompatible (needs extra coding)
2. cache should not be copied

[scubamuc]

copy file tree of rainloop into snappymail

• not using plugins -

1. copy file tree without cache

• using plugins -

1. deactivate plugins in rainloop
2. copy file tree without cache
3. activate (alternative) plugins

[the-djmaze]

@scubamuc you're almost right.
I've added concept of the code in above commit.
This doesn't copy directories named plugins nor cache and makes a list of the plugins to install later on.

[pierre-alain-b]

This looks great! Do you want to call it when doing the initial deployment of snappymail in nextcloud or to have a button in the admin part to trigger it?

[scubamuc]

@pierre-alain-b would you make the button disappear once it has been triggered, since it is a "one-time" action?

[the-djmaze]

Try: https://github.com/the-djmaze/snappymail/releases/tag/v2.19.2

[scubamuc]

@the-djmaze i'm afraid the last build (2.19.2) has an issue with account credentials.... authentication fails and there is no way to retrieve the password for admin.
Any ideas?

[the-djmaze]

Did you try uninstall and install again?

[scubamuc]

yip, tried several times on different instances... fails on -snap and hosted, using different browsers and private mode, same authentication error.
