3 Issues - Entry Posting & Cross-posting

[jimmyb]

So I finally started to play around with my DW-install and I've come across 3 issues so far.


Upon visiting http://www.mysite.com/manage/circle/add.bml?user=USERNAME or http://www.mysite.com/manage/circle/ you get the following error:

[Error: Invalid type 'Q' in pack at /home/dw/cgi-bin/DW/User/Edges/WatchTrust/Loader.pm line 276. @ deathnote]

The line previously read:

my $packfmt = "NH6H6QC"; # pack format

Changed to:

my $packfmt = "NH6H6NC"; # pack format

Now I really have no idea how the packfmt works, but changing the Q to an N fixes the issue...so maybe someone couple explain what it is, and how it works, and what the letters mean? And why using N fixes it...


When submitting a new entry, an error message came up. The entry still posts, but tags are not included in the new entry. Line 1492 in cgi-bin/LJ/Entry.pm.

The line previously read:

$row = pack("NNNQN", $item->{'posterid'}, $eventtime, $logtime, $sec,

Changed to:

$row = pack("NNNNN", $item->{'posterid'}, $eventtime, $logtime, $sec,

Again, another pack issue, and changing the Q to an N fixes the issue.

I setup my account to cross-post to Scribbld and when I attempted to cross-post, this error message was entered into the 'error' table in The Schwartz database:

Can't call method "pre_crosspost_hook" on an undefined value at /home/dw/cgi-bin/DW/External/XPostProtocol/LJXMLRPC.pm line 275.

That line reads:

$req = $extacct->externalsite->pre_crosspost_hook( $req );

Thanks for any help on the issues & I am really excited about this codebase!!

Real fast:

#1/#2 are because Dreamwidth requires a 64-bit version of Perl and therefore Linux. Q is a 64 bit data type.

#3 sounds like you didn't create a DW::External::Site::Scribbld (or whatever, I'm tired) module, so it doesn't have all of the tools it needs to crosspost.

[jimmyb]

#1/#2 - Hrmm, I'm running 32bit...so I guess that's why it's giving those errors...in that case, what kind of things am I breaking by not using Q and 64bit?

#3 - Thanks, I made the package, I just duped one of the modules and edited it. So now I don't get the previous error message, but I do get "Missing argument" in the error message in the database...I could pastebin my module if you want to peek at it, but it's pretty much the same as the others, just customized with Scribbld's information!

Thanks Mark!

The 64 limit on trust groups (or 62, or whatever the exact limit on Dreamwidth is) is one that jumps to mind immediately.

[jimmyb]

What do you mean by limit? Limit of users allowed per "trust group", I assume a "trust group" is just your friends? Or something...?

Thanks!

http://www.dreamwidth.org/support/faqbrowse.bml?faqid=77 (Sorry, they're called access filters on DW. You can have up to 60-something, as opposed to the 30 friends groups you could have on LiveJournal code.)

[jimmyb]

Oh okay...so I wonder what changing that Q to an N allows you to have haha...

I really have no idea what I'm doing to be honest, the rest of the characters are N, so I figured why not change this Q to an N...

[pauamma]

Probably 0, because the code expects a 64-bit integer just about everywhere else, so the net result is that you'll break access groups completely.

Really, you need a 64-bit environment, not a 32-bit one. If you want to stick with 32-bit, your best starting point is LJ code, not DW.

[jimmyb]

Haha oooh awesome. That would have been fabulous to know in the install docs, eek...so that brings upon another question, is the data stored in MySQL able to be transferred into a 64bit OS install? Is the data in anyway stored in a way that has something to do with 64bit/32bit? Or could I just install Ubuntu in 64bit mode, and then move the database over without breaking (too) many things?

Thanks! :)

http://wiki.dwscoalition.org/notes/Suggested_Server_Requirements, which is linked from http://wiki.dwscoalition.org/notes/Category:Dreamwidth_Installation. If you have a wiki account (you can create one using OpenID authentication), you can talk to foxfirefey to get edit privs and add whichever entries or links you think are missing.

I don't have answers to the rest of your questions, I'm not a MySQL admin.

[jimmyb]

Haha oh man. Thanks, you're amazing. Haha.

Fortunately, I'm not using memcache, so maybe I'll be safe. I'll have to go back and change what I changed to L's and see how that works.

And you're not a MySQL admin, sheeesh. I thought you were Mr. Super Duper! LOL. Seriously though, that's cool. You've definitely helped me a lot in understanding all this and I really appreciate it.

Thank you!!!

Ok, I actually got a bit further, I had messed up a parameter in DW::External::Site. So now it appears to work, but nothing actually gets posted to Scribbld. I did a test with cross-posting to LiveJournal and that does work...

Is there any place I can look (either on Scribbld or my DW install) to see if something isn't going through properly?

[jimmyb]

afuna Helped me on IRC for #3, finally figured it out. I simply had to restart my Schwartz jobs haha.

I created a DW::External::Site::Scribbld which works if you want to include that in the DW code.

Thanks!!

Just for reference, the pre_crosspost_hook error is a bug. You should be able to define an ExternalAccount without having to go into the code and define an External::Site, too. That's what the 'Other Site' option is there for.

Either we need to do a null check there (easy solution) or we need to create a new generic External::Site object for the custom site (a bit more elegant, but would call for more code rewriting).

[jimmyb]

Ah okay, cool, thanks :)
