When you use something like this in a plugin

TWiki::Func::saveAttachment($web, $topic, $fileName,
                            { file => $tempName,
                               filedate => $fileDate,
                               filesize => $fileSize,
                               filepath => $fileName,
                               comment => "Generated by !AttachContentPlugin"

Then you get this kind of garbage in the meta

Why do we get these useless parameters?

stream="GLOB(0xa421c98)" tmpFilename="/tmp/Z4IDRIcEXv"

This is found both on 4.0.4-4 and on MAIN

The quick testcase for this is to use the AttachContentPlugin and make a topic with this.

Some test text
And a little more


They happen to be lying around in Meta. They are cache parameters, same as most of the content of META:FILEATTACHMENT.

Perhaps a bit inelegant, but not a bug.


Then let us call it an enhancement though still with low priority. Peter and I discussed this on IRC and we agreed that this garbage should not be in the META:FILEATTACHMENT. There should only be the parameters that are actually useful. And having a value saying GLOB(0xa421c98) is right out bad programming.

I spent hours trying to find out what I did wrong using TWiki::Func::saveAttachment and others will for sure have the same experience.

I am getting pretty annoyed about how quickly bug items are being discarded here without dialog, and I want that discussed at next release meeting. It is really annoying me and I know others are annoyed about it as well.


These extra parameters are harmless, but also pointless and should be gardened out before saving the topic. However this requires a spec of what should be saved in %META:, which opens a whole other can of worms, related to Item773.

This appears to be fixed in Trunk - I'm not seeing any stream or tmpFile attributes being created with either web attach or the Func API. Attributes were delete as part of Item4695 restructuring of Store and Meta.
