Repl server on iOS?
by mikel evins 11 Sep '11

11 Sep '11

Marc, I'm finding that the repl server in the source for Gambit REPL appears not to work. At least, when I try a telnet to an iOS device running Gambit REPL, the connection is refused. The same goes for my own app if I include the remote repl code, do a (start-repl-server), and try to telnet to the device. It'd be mighty handy to have that repl server working. --me

These changes tweak acos (special-casing (acos 1) => 0 (all exact)) and complex division (using the naive algorithm in fewer cases). Brad

Too many open files with process
by Adam King 09 Sep '11

09 Sep '11

I need to descend a directory structure with ~5000 files in it and run an external process on each to gether information on each file. However, after running over about 250 files, I get a "Too many open files" error. 250 is probably OSX default max open file limit - but I don't understand why the 'with-input-from-process' doesn't appear to be closing its file handle? I also tried with 'open-input-process' and 'open-process' and manually calling 'close-input-port' but didn't help. Here's a small script that shows the exact same prob: (define (test-fn) (define (do-process) (with-input-from-process (list path: "pwd") read-all)) (let loop [(count 2000)] (if (> count 0) (begin (do-process) (loop (- count 1))) (println "Done")))) (test-fn) And the output: bigmac:iosTexConverter aking$ gsc -v v4.6.1 20110519175028 i386-apple-darwin10.8.0 "./configure /usr/local/Gambit-C/share/config.site /usr/local/Gambit-C/etc/config.site" bigmac:iosTexConverter aking$ gsi ./test.scm *** ERROR IN loop, "test.scm"@9.11 -- Too many open files (with-input-from-process '(path: "pwd") '#<procedure #2 read-all>) bigmac:iosTexConverter aking$ Running latest from the Gambit git repo and OSX 10.6.8. As far as I can tell, calling 'pwd' shouldn't be leaving around open file handles. I also checked the process-status, and it was 0. Any suggestions?
