[tbnl-devel] tbnl freeze
by Steve Huffman 30 Apr '06

Hi all, I'm working on reddit.com, which uses TBNL as its web framework. For the most part, all is well, but I've been running into an error lately that is causing me to worry. Basically, the symptom of the problem is that our website appears to pause, and all requests just hang (eventually they'll timeout on the browser side). I work against our server using remote SLIME. The SLIME session does not hang, but in order to bring the website back to life I log into our web server, use attachtty to view the running lisp process, and hit ctrl + c a few times, after which a debugger will pop open in Emacs that I can abort. I'm running CMUCL 19a on a FreeBSD box. I use apache and mod_lisp in front of TBNL. I haven't been able to find out what causes this lockup, nor do I understand why I must open the process on the web server (when I'm already cruising in SLIME) to wake it up. Has anyone seen any issues like this before? Or perhaps know if this is even a TBNL issue? I've pasted the output I see from the lisp process (via attachtty) and in my emacs session (after I send an interrupt). Any help would be greatly appreciated, Steve Huffman In attachtty I'll see something like this: Interrupted at #x2811F14E. [Condition of type SIMPLE-CONDITION] Restarts: 0: [CONTINUE] Return from BREAK. 1: [DESTROY ] Destroy the process Debug (type H for help) (UNIX::SIGINT-HANDLER #<unused-arg> #<unused-arg> #.(SYSTEM:INT-SAP #x47FD789C)) Source: Error finding source: Error in function DEBUG::GET-FILE-TOP-LEVEL-FORM: Source file no longer exists: target:code/signal.lisp. 0] and in emacs I'll see something like this: Interrupted at #x2811F14E.

[tbnl-devel] problem starting tbnl
by quasi 22 Mar '06

Hey, (tbnl:start-tbnl) does not return. It is supposed to return *Listener*, right? Ctr-C gives option to abort. Even if it does not return, the tbnl demo runs till I abort. I am running SBCL 0.9.9 on Debian AMD64 testing. Apache2 installed via apt-get and latest mod_lisp.c from repo downloaded 2 weeks back. TBNL and dependencies are latest. thanks, quasi
