Chronological order of wikis completely disrupted by import

After the import from VW3 to VW4 all wiki articles have lost their chronological order. i.e. many hundreds of old articles appear as if these are newly edited.
For example with reasons like this:
Reason: converted link format during import

In many cases the author of the 'automatic edit' has not been around for years or is even diseased.
Its not a good idea to have these placeholder edits appear like this.
Its important to display the most recently edited articles first.

It will take years to get the articles back in chronological order.

It is important to provide the automatic edit instead of replacing the old edits, in case you need to reverse the automatic edit. I have updated the importer so that automatic edit will take place 1 second after the expected recent edit. This should not throw off the validity of Special:RecentChanges as much as before.

This does not seem to be fixed in 4.0.8b3

You are right. This change missed the cutoff for 4.0.8 by a few hours. The corresponding changeset is actually scheduled for the following release.

You can apply the change manually if you will be running your live import. In vault/core/controller/import/handle/vw3/link/vw.php, find:

Code:

$pagedm->set('pagetext', $page['pagetext']); $pagedm->set('reason', 'converted link format during import');

After it, add:

Code:

if (!empty($page['edit_dateline'])) { $pagedm->set_info('custom_dateline', 1); $pagedm->set('edit_dateline', $page['edit_dateline'] + 1); }

This will make the fake edit take place 1 second after the last real edit, which will have a negligible effect on chronology.

Are there other issues related to my site that are not in the current build?

I see some other vBulletin 3-only fixes still on the development branch, but they are not related to import. They are related to search functions. If you encounter those, I can post the patches for you.

Weird. After applying the patch it doesn't fix the issue. Yet, I have seen that you did fix the issue before I overwrote all files with the current build.

I will have to check again. It's possible setting a custom date is only working correctly for historical versions and not "new" edits. Did you run a fresh import, or try to re-import over the previous one?

I reimported over the previous one. I will do a fresh import once I do not encounter issues with reimport, because fresh copy of the site takes effort to setup due to the complexity of the big board.
it indeed relates to 'new' edits. For example creating a category page.

Re-importing over the previous import will use the last date (which was incorrect) for the fake edit, since the fake edit must be the current edit, and the current edit must be the most recent. This would explain why you thought the issue was not fixed. I checked some of the articles where a 'converted link format' edit appeared, and indeed it appears in the history 1 second after whenever the previous edit was. So this appears to be working correctly with the change I gave you above.

To be clear, you do not have to create a new copy of the site every time you want to re-import. You can achieve a fresh VaultWiki by uninstalling+reinstalling VaultWiki, or you can actually do this by modifying the file vault/core/controller/cp/impex/vw.php, and adding the following to the top of the execute() block:

Code:

$this->clear();

The next time you visit the importer, it should delete all non-default content from the wiki. Absolutely, remove the code after you confirm the wiki is now empty. You don't want to accidentally delete the whole wiki later when you want to keep it.

Regarding categories, it took me a while to understand why you mentioned it, but it appears that categories that did not exist as pages already but that were referenced by the "category" BB-Code were being created at the current time rather than at the time of the "conversion" edit. You can fix this like so.

In vault/core/controller/dm/page/vw.php, add the following method to the class:

Code:

	public function get_current_dateline()
	{
		if ($this->instance->get_info('custom_dateline'))
		{
			if ($this->instance->get_existing('pageid'))
			{
				return $this->instance->get_info('edit_dateline');
			}
		}
		else if ($this->instance->get_existing('pageid'))
		{
			return vw_Hard_Core::controller('Request')->timenow();
		}

		return $this->instance->get('dateline');
	}

Find:

Code:

$this->categorydms["$key"]->add_type('Category');

After it, add:

Code:

$this->categorydms["$key"]->set('dateline', $this->get_current_dateline());
