22:32:58 stassats i guess i've acquiesced to the fact that i can't escape emacs

22:33:06 stassats gotta start making slime better again

23:42:12 phoe thanks!

23:43:42 aeth maybe something could come from this discussion from 2019? https://sourceforge.net/p/sbcl/mailman/sbcl-devel/thread/20190507014112.wiwiles2vofjmbop%40Ergus/#msg36659403

23:43:45 aeth (maybe something has?)

23:44:11 aeth at least, someone was looking into porting Emacs's Lisp to sbcl

23:44:15 stassats that's a long thread

23:45:05 stassats it doesn't seem like the language is the biggest problem of emacs

23:45:18 stassats and its runtime

1:09:20 stassats huh, after i load cl+ssl i can no longer interrupt slime

1:12:06 stassats and on macos only

1:14:36 stassats and only if i load ssl from homebrew, not the system one

1:22:50 stassats and only when i do cffi:load-foreign-library, but not sb-alien:load-shared-object

1:22:53 stassats what the

1:27:56 stassats ok, cffi does (call-within-initial-thread 'load-shared-object path)

1:28:36 stassats which is bad in itself, but why the differences

1:32:40 stassats adding sb-sys:with-interrupts to call-within-initial-thread helps

1:32:52 stassats but how could it affect the repl thread

1:33:04 ieure I'm trying to use gzip-stream, but it doesn't seem to work and I can't find any examples. Can anyone point out what I'm doing wrong here? http://paste.debian.net/1262099/

1:33:46 stassats i think that's more of a question for #lisp

1:33:54 ieure I suppose you're right.

1:34:35 stassats is it a binary stream?

1:34:46 stassats can you do (write-byte 20 stream)

1:37:46 |3b| ah, is that the one where sb-gray functions don't work on non-gray streams?

1:38:20 stassats well it says fundamental-binary-output-stream right there

1:38:30 ieure stassats, (write-byte 20 zfd) does work.

1:38:45 |3b| yeah, looks like it does just call it on underlying stream https://github.com/mcna/gzip-stream/blob/master/gzip-stream.lisp#L92-L93

1:38:59 ieure I guess if I'm writing gzipped stuff the underlying stream needs to be binary, which I didn't specify.

1:40:02 stassats slap a flexi stream on it

1:40:26 stassats like in https://github.com/mcna/gzip-stream/blob/master/gzip.lisp#L3

1:43:38 stassats the stream-write-char method is highly mysterious

1:44:02 ieure Okay, yeah, that works. Thanks for the pointer.

1:44:53 stassats ok, back to the signal mask mystery

1:46:07 |3b| i guess they think you might like raw text mixed in with your gzip?

1:48:53 stassats i wish i could just trace pthread_sigmask

1:50:31 stassats but i can't imagine how interrupting a thread and loading a shared library there can affect the signal mask of another thread

2:00:00 stassats no interrupt is needed, load libcrypto.dylib in another thread with a different sigmask, all other threads get that sigmask

2:00:46 stassats looks like a kernel bug or something
