annotate src/print.c @ 5868:da732079c58d
Correct some code with badly-placed parentheses, thank you Mats Lidell.
lisp/ChangeLog addition:
2015-03-16 Aidan Kehoe <kehoea@parhasard.net>
* tty-init.el (make-frame-after-init-entry-point):
Some parentheses were placed badly here with the last change,
thank you Mats for pointing it out; in passing, change to a
version of the code that doesn't create a string for garbage, not
that it matters.

| 629 However, if PRINTCHARFUN is a frame, printing of complex | |
| 630 structures becomes very expensive, because `append-message' | |
| 631 (called by echo_area_append) gets called as many times as | |
| 632 output_string() is called (and that's a *lot*). append-message | |
| 633 tries to keep top of the message-stack in sync with the contents | |
| 634 of " *Echo Area" buffer, consing a new string for each component | |
| 635 of the printed structure. For instance, if you print (a a), | |
| 636 append-message will cons up the following strings: | |
| 637 | |
| 638 "(" | |
| 639 "(a" | |
| 640 "(a " | |
| 641 "(a a" | |
| 642 "(a a)" | |
| 643 | |
| 644 and will use only the last one. With larger objects, this turns | |
| 645 into an O(n^2) consing frenzy that locks up XEmacs in incessant | |
| 646 garbage collection. | |
| 647 | |
| 648 We prevent this by creating a resizing_buffer stream and letting | |
| 649 the printer write into it. print_finish() will notice this | |
| 650 stream, and invoke echo_area_append() with the stream's buffer, | |
