* Data length limit in Guile/Geiser/Scheme evaluation @ 2018-11-15 14:21 Neil Jerram 2018-11-15 14:26 ` Neil Jerram 2018-11-15 15:20 ` Nicolas Goaziou 0 siblings, 2 replies; 12+ messages in thread From: Neil Jerram @ 2018-11-15 14:21 UTC (permalink / raw) To: emacs-orgmode, geiser-users [-- Attachment #1: Type: text/plain, Size: 648 bytes --] I seem to have hit a limit in how much data can be successfully passed from Org to Geiser and Guile. The attached file demonstrates this. With the file as attached, and hitting C-c C-c on '(length classification)', I get 139 (which is correct). If I add one more (duplicate) row to the table, and hit C-c C-c again, the evaluation hangs somewhere and Emacs is blocked until I interrupt with C-g. Has anyone else seen this? Is there a fix? If not, any ideas for how I can investigate further? I love doing stuff with Org and Scheme code, so really hope that I don't have to have my wings clipped by this apparent limit.

I think something like this should be done, not only in the Guile initialization, but ideally in the generic Geiser code that connects to inferior processes via pseudo-tty. After the pseudo-tty is allocated but before launching the inferior Scheme process, something like "stty --file=/dev/pts/N -icanon" should be run. However, before doing this, some warnings are in order: When in noncanonical mode, the normal processing of ERASE (usually DEL or Ctrl-H) and KILL (usually Ctrl-U) characters are disabled, and input characters are delivered to the subprocess immediately as they are typed, rather than waiting for the newline as normally happens in canonical mode. At least in the case of the Guile REPL, one notable side effect of running in noncanonical mode is that when a list is entered at the REPL, the 'read' returns as soon as the final close parenthesis is entered. Nothing after that is read, not even the usual newline. The final newline is only read if the reader is not yet sure that it has finished reading the token, e.g. if a number or symbol is entered. In those cases, typically any delimiter may be typed to terminate the read, e.g. space. To see this, you can try running Guile from a traditional terminal program (e.g. xterm or GNOME Terminal), and type: (system* "stty" "-icanon") and then: (display "hello") You will see that as soon as you type that close paren, "hello" is immediately printed, followed by another REPL prompt, all on the same line. You might also try (use-modules (ice-9 rdelim)) and then: (read-line) and you'll see that the newline you type at the end of that line is read by 'read-line', which then immediately returns the empty string. The input that you wish for 'read-line' to see must be typed on the same line, immediately after the close parenthesis. So, it might be that Geiser needs to be adjusted somewhat to deal with these differences. Finally, you might consider the possibility that 'stty' might not be available in PATH, or fails for some reason, and ideally this case should be handled as well. It might be simpler to always use REPL servers over a socket, than to deal with these headaches, although I don't know if that will be an option for the other Scheme implementations.

There's an additional wrinkle here: after 'read' returns, Guile tries to read optional whitespace followed by a newline, but only if it's immediately available. See 'flush-to-newline' at the end of module/system/repl/repl.scm in Guile. So, unfortunately there's a race condition here, but typically if you send the newline immediately after the final character of input, it is likely that the newline will be consumed by the REPL reader and not by the code that is subsequently run. Finally, I should note that I consider this race condition suboptimal, and will likely change how Guile behaves in the future, so please don't rely on the behavior I have described above. I will likely change Guile's REPL reader to wait for the final newline in all cases. Mark ^ permalink raw reply [flat|nested] 12+ messages in thread

I think this is not an actual problem in Geiser. In comint mode, the stdin of the Guile process doesn't receive any input bytes until higher level elisp functions send them, and that's totally under our control. Repeating that experiment in a Geiser REPL, nothing is printed before a RET (and, in fact, we might not even send the RET to Guile). > > You might also try (use-modules (ice-9 rdelim)) and then: > > (read-line) > > and you'll see that the newline you type at the end of that line is read > by 'read-line', which then immediately returns the empty string.

Not for all of them. For Guile it's doable, but definitely not "simpler", it requires some work and solving some unrelated corner cases; but it might be worth the effort, because it's a cleaner interaction mode (for instance, behaves much better in the presence of multiple threads).
