Sitting in my London hotel room waiting for the conference call with folks in three cities that are not London. The glamorous life of the road warrior. I keep thinking I should make time to see Xof, but, of course, I can't 'make' time (even though I live near CERN...).

is there a way to catch SIGTERM and SIGINT signals in sbcl? i've tried trivial-signal, but the examples provided do not work; e.g. sending INT only invokes the sbcl debugger but the signal handler does not run.

after some idea generation in #lispcafe, i present the magrathea anti-vulnerability scanner hunchentoot mixin
8:54:22
no-defun-allowed
it works just like the hunchentoot easy-acceptor but if you load too many "sketchy" URLs in too short time, it zipbombs you

what i want to do: i want to react to TERM so that i can invoke a proper shutdown routine on the server, doing some cleanup.
8:55:39

hjudt: if I had to guess I'd first disable interrupt for that signal in sb!unix package
8:57:11
jackdaniel
(sb-unix::enable-interrupt sb-unix::sigterm :ignore) ; and see if trivial-signal starts working after that

also regrading graceful exit I think there may be a nice interface for adding exit-hooks
9:10:55
hjudt
thanks. i have added a function to sb-ext:*exit-hooks*, which gets called. additionally setting sb-ext:*timeout* to a lower value than the default 60 also solves my problem that sbcl takes too long to shutdown.

Pretty sure we call it cl, unless you want an editor that only works with gnu clisp.
10:39:20
jackdaniel
clisp is one of many common lisp implementations, abbrev for common lisp is CL not clisp
10:41:08

I might write an editor after Netfarm and Magrathea, but it won't be very emacsy, as it'll work on abstract syntax trees or actual lisp structures.
10:42:26
jackdaniel
I believe that's what beach works on with Second Climacs (and that was discussed briefly a few days ago on this channel)
10:45:35

I remember I made an image of it which also loaded a climacsrc for the hell of it and wrote a hello world extension.

Also, it has a better out of the box experience than slime+emacs IMO, I still can't get company mode out of dumb "I see a symbol, I suggest that symbol" mode.
10:50:28

clisp is written in c, ecl's core is written in c as well, sbcl is written in common lisp, ccl is written in common lisp, abcl is written in java
10:51:23

SBCL and CMUCL are partly done in C for stuff like the garbage collector and the "everything went horribly wrong" debugger.
10:52:20
jackdaniel
Necktwi: here you have a brief listing of CL implementations: https://common-lisp.net/project/ecl/static/quarterly/img/vol4/all-hierarchy.png
10:54:22
no-defun-allowed
jackdaniel: CMUCL and SBCL do use C for the lowest level parts of their runtimes. I like scaring people with gencgc.c for example.
10:57:29
jackdaniel
no-defun-allowed: they have some modules written in C, that is not the same. but now I udnerstand what you mean.
10:58:53
jackdaniel
also saying SICL is a Common Lisp implementation may be considered a little bit of exaggeration given it is not complete, I think a more proper term would be: a set of modules written in CL
10:59:40

Necktwi: are you here to learn something or just reject every opinion that does not match your own?
11:00:08

Necktwi: common lisp is language standard, implementations are free to be written any way they like to. There IS NO reference implementation.
11:00:10
jackdaniel
no-defun-allowed: that doesn't make sense to me. GCL is working ClTl2 implementation with some ANSI parts (so in this sense it is a finished working project)
11:00:19
no-defun-allowed
jackdaniel: I probably wouldn't want to run CL without a garbage collector, so it's a fairly crucial component of a Lisp system.
11:01:21
no-defun-allowed
clisp is the shitslow one -- oh we're talking about standard by "I'm the leader implementation"
11:02:55
jackdaniel
Necktwi: this kind of discussion belongs to #lispcafe - I suggest all interested should move it there. we've already left CL land with it to some opinions about compilers.
11:03:33
no-defun-allowed
Necktwi: if you don't want a garbage collector, you can take it to #rust or #c++ probably.

jackdaniel: idly trying ecl again, I see a lot of shifting a negative signed value is undefined [-Wshift-negative-value] in the output, hundreds of warnings when compiling lisp code
11:44:30
jackdaniel
shifting is for int integer <-> fixnum conversion (fixnum is an immediate), this is correct. we could possibly do something with a warning, but I'm not sure how to hid it
11:47:31
jackdaniel
sorry, I have two pans on fire (making dinner) can't help you more at this moment
