Caissa

[ioffe]

This one will be the official Caissa thread. Hate it or love it, please leave your feedback. Any feature requests, bug reports, and etc... post it here. I will try to do my best in order to assist you. But I may not be able to, since we are all working in the unauthorized environment.

Hi

It doesn't work for me under 1.1.1. When I open the application, the woman (presumbly Caissa ) appears and then the application quits after a few seconds.

I sshed to my iPhone and tried to start Caissa manually. Here's the output:

# pwd
/Applications/Caissa.app
# ./Caissa

[lots of stuff skipped]

2007-12-28 17:41:03.170 Caissa[14177:d03] ChessEngineController -> init
2007-12-28 17:41:03.175 Caissa[14177:d03] ChessEngineController -> processEngineOutput -> _ismymove= 1
zsh: permission denied: /var/root/Library/Caissa/sjeng
zsh: segmentation fault ./Caissa
#


When starting the underlying engine (sjeng) manually, I get a permission denied:

# pwd
/var/root/Library/Caissa
# ./sjeng
zsh: permission denied: ./sjeng
#


Funnily the same permission denied happens, when I create a shell script and try to execute it. The permission appears to be correct though:

# ls -l sjeng
-rwxr-xr-x 1 root wheel 224724 Dec 26 18:47 sjeng


Any ideas?

Smurfie

PS. Are you using the UCI protocol to interface with the engine? If so, that would mean I could use my engine instead to play against. Fun fun

[Eurisko]

Yeah, give it permissions.. chmod 755 /var/root/Library/Caissa/sjeng

[Smurfie]

Yeah, give it permissions.. chmod 755 /var/root/Library/Caissa/sjeng

But it HAS permissions. Even full permissions (chmod 777) won't work.

it won't work. it is about how you hacked your iphone. Your mount to /private is done with noexec option. User Loki did huge investigation on that one. I am thinking if I should make specific release, for those who suffer and have ~3mb space in their /application folder. But It's just so UGLY.

Ah.. that explains a lot. I hacked my iPhone with Independence (v1.2.4 I think) I will try to find some more info in these forums about it then. If someone has one or two good links, maybe he could post it in this thread here as well. Thanks.

I was gonna ask why there's another thread, and why this one is the "official", but then I realized ioffe is the author.

REALLY need that undo option, brother! My big ol' fat fingers keep moving the wrong piece, and it screws my whole game up.

And some alternative boards...which Eurisko has promised to upload later tonight.

I am making good progress on undo. So far it can undo just moves. I need to work some more on undo's for "passing pawn" takes and castling undos. I think we are on track with 0.83 release.

[HotStuff2]

Oh wow...most games don't implement the "en passant" rule. Nice. I'd be happy with just simple undoing right now though!

[Eurisko]

Ok, here are the boards, and an example. Put them in Caissa.app/chessboards

[ioffe]

Eurisko
good stuff, the aqua board is just awesome. Thanks a lot.

Shoot me email to dev at caissa dot us. I'll hook you up with nightly build(it may look strange)

Hi

It doesn't work for me under 1.1.1. When I open the application, the woman (presumbly Caissa ) appears and then the application quits after a few seconds.

Can you do me a big favor?

can you post the content of your

cat /private/etc/fstab

here ?

[s55b]

where can i download caissa direct?
i donīt like the installer

[HotStuff2]

I'm sure I'm not the only person wondering this: how did you pick "Caissa" as the name? Is it from Caissa's Web Free Online Chess?

[Smurfie]

Can you do me a big favor?
can you post the content of your
cat /private/etc/fstab
here ?

Sure, here it is:

# cat /private/etc/fstab
/dev/disk0s1 / hfs rw 0 1
/dev/disk0s2 /private/var hfs rw,noexec 0 2
#

Did anyone try to simply remove the noexec option? And did the phone still work?

Edit: Ok, I've removed the noexec option and now Caissa starts w/o any problems.

Smurfie

[HotStuff2]

ioffe sent me the nightly build with undo....suh-weet! Exactly what Caissa needs. It's damn near perfect now, IMHO.

Been playing Caissa for the past hour or two. This has now become my favorite iPhone game.

@Smurfie
Can you please tell exactly what you did ?, cause I have the same problem

[ioffe]

@Smurfie

The procedure is on our wiki www.caissa.us .

0.83 is on track for tomorrow. I have rewritten "queen to pawn" logic from ground up and finished undo logic, the rest is undisclosed for now


One more thing
If any1 has 1.0.2 and also has ssh access to the file system. Please contact me, I will try to help you to get it working.

[armadillo]

ioffe, can you please remove the poll option from the official thread? I understand that you want feedback, but I hate it when your thread shows up as unread and there is no new post, just someone voting. I actually would suggest that the mods disable polls entirely or that votes don't mark the thread as new.

[ioffe]

Armadilo

I'd love to do that. I got all feedback I need at this point. I just can't figure out how

[luistohe123]

I received multiple emails suggesting that Caissa doesn't work on 1.0.2 firmware. I can't comment on that, since I don't an have opportunity to test on anything other then 1.1.1 IPhone.
if you have problems with 1.1.1, run this command:
# cat /private/etc/fstab
/dev/disk0s1 / hfs rw 0 1
/dev/disk0s2 /private/var hfs rw,noexec 0 2

WARNING: ON YOUR OWN RISK
if you see the output that has noexec flag, remove it and reboot your iphone.
If you didn't fry your phone and Caissa works for you, find the donate button down bellow.

THIS IS THE METHOD, BUT I DONT HAVE SHH WORKING RIGHT NOW (cause of stupid Toggle ), SO WITH WHAT OTHER PROGRAM OR APPLICATIONS CAN I WRITE THIS COMMAND?
