Why is that? Lyxconfig says max uploadable files are 50MB.

LynxChan just completed it's third year and I must say, this project's past year was pretty good. More and more sites running it, including 2 more that migrated and have a considerable amount of traffic. 1.9 and 2.0 fixed it's oldest woes, eliminating slow build times entirely and making the cache much more robust.

Moving forward, I have realized that user-owned boards just didn't caught on. To this day, endchan is still the only LynxChan with relevant traffic that allows it. While I don't think it's worth doing a 180 on how settings and features work to change the focus of the engine, I am going to focus on improving features that benefit sites without user-owned boards. For this, I really encourage chan owners to bring me suggestions of areas that can use improvement for these sites.

I'd like to take this time to thank everyone who contributed this past year. Megamilk, for giving 1.8 and later versions a proper real-world testing. Odilitime for taking his time to test 2.0, which revealed a serious bug. And fapchan for giving a proper migration to be performed, it really helped to pave the way for future migrations.

I'd also like to remember past contributors such as lleaff for giving valuable insight on the very early stages of development, dunecoon for his work with front-ends and doke for designing the face of the project.

What is known about this claimed exploit?

Cat Board owner 12/28/2017 (Thu) 11:21:02 Id: 36351e No. 496
Aside from the possibility of running mongo accepting external connections without authentication enabled, nothing.

I am skeptical of anything that mentions or involves smiley, that image reeks of goon trolling. I figure the first place to be owned would be a large site, like mewch or endchan. At least this one, since its managed by me.

Broken HTML generation OP 01/18/2018 (Thu) 17:44:42 Id: 61d67f No. 517
Markdown links containing quoted text or quotes to posts generate invalid HTML. For example:

http://google.com/ class="quoteLink" href="/lynxchan/res/505.html#507">>>507
http://google.com/ class="quoteLink" href="/lynxchan/res/505.html#507">>>>/lynxchan/507

This could have security implications (the resulting HTML looks quite bad), but I cannot find a way to exploit it at first glance. Suggested fix:

diff --git a/src/be/engine/postingOps/common.js b/src/be/engine/postingOps/common.js
--- a/src/be/engine/postingOps/common.js
+++ b/src/be/engine/postingOps/common.js

ty, ill look into it

Fixed, all I had to do was to process links before quotes.

Fixed only on 2.0, I will fix on 1.8 and 1.9 if I find some way to exploit that.

But given how stuff is sanitized anyway, I don't think that would be possible.

Markdown in /<board>/catalog.json API Cat 01/23/2018 (Tue) 00:56:37 Id: 24b91a No. 521 [Reply]
Is there any reason that the catalog API json doesn't have the comment in markdown? The API has markdown in the thread views, but not catalog.

Cat 01/23/2018 (Tue) 21:08:40 Id: 04c95d No. 522
If you are the guy that e-mailed me, there is no good reason and I added it on 2.0.
