Question regarding PK7's/LZMA

[Ænima]

I remember a while back (like 2 or 3 years ago), Wartorn explained to me that PK7's (aka PK3's compressed using the LZMA algorithm) would have a tendency to cause significant memory leaks when hosted online.

Is this still the case, or has it been fixed? If not, my next question is: Can it be fixed, or is it something that's unavoidable due to the LZMA structure?

If it can be fixed, I have a feeling that I'm going to be told to "go suggest it over at G/ZDoom". But I feel like it would be forever until they finally get around to it (client/server issues aren't really their top priority).

If it hasn't been fixed yet, and it is indeed something that's fixable, can the Zan developers please look into this? c:

Start a local server with a pk7, add some bots, open task manager, look at the memory usage.
Come back an hour (or less) and see if it is roughly the same amount.

I used to run some .pk7 ZH addons and didn't notice anything out of ordinary happening there. I would like seeing .pk7 used broadly if it's trouble-less.

Is this more than a rumor? I have never seen this happening myself.

[Ænima]

Me neither, but I figured that Wartorn was pretty well-articulated in client/server mumbojumbo so I took his word for it. I'll run some tests for myself the way Llwellyn described when i get a chance and then I'll post results.

I didn't know that Skulltag Zandronum supports pk7s.

[TerminusEst13]

I didn't know pk7s actually existed. Here I thought people were typoing pk3.

A quick look on the wiki about the advantages make it seem especially interesting, though.

It is quite a surprise, I also didn't know that .pk7s existed until now, but if .pk3 = .zip and .pk7 = LZMA/.7z then .pk7 > .pk3

It would be awesome if modders switched to .pk7 instead of .pk3

Well that's ultimately what I intend to do, but only if i'm 100% sure that there are no drawbacks.

I've known about pk7s for a while, i've just been hesitant to use them.

[Bloax]

Well, big stuff (and this isn't necessarily in solid mode, either) like AOW2 seem to get a dramatic increase in loading time with LZMA.
Though this does seem new to me.

Well that does makes sense considering it's a much "denser" compression.

Once I figure out how, you'll be certain I will. :p

Can Slade open .pk7s now?

[Theshooter7]

The only thing I'm a bit curious about is if pk7 support has been fully fixed. I remember when trying to convert WDI into a pk7, the music was broken for some reason. This was in both SkullTag and Zandronum.

The discussion for it was here.

Just tried, doesn't seem so.

No. I'm still waiting for the minimal example wad I asked for in http://zandronum.com/tracker/view.php?id=838#c3629
