annotate src/print.c @ 5904:ee27ca517e90
Revise print_symbol(), never calling is{float,ratio}_string().
src/ChangeLog addition:
2015-05-08 Aidan Kehoe <kehoea@parhasard.net>
* print.c (print_symbol):
Revise this. No longer call isfloat_string() and isratio_string()
on practically every symbol seen; check explicitly for the known
float format in this function, which turns out to be a more
limited and cheap job than you would think.
Also check for integer and ratio syntax in passing.
Use Vdigit_fixnum_map when working out whether a given character
is a digit.
* lisp.h:
Make Vdigit_fixnum_map available generally.
tests/ChangeLog addition:
2015-05-08 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-reader-tests.el:
Check read and print handling of symbols that look like
numbers. In passing, check the read and print handling of the
associated numbers.

| 629 However, if PRINTCHARFUN is a frame, printing of complex | |

| 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), | |

| 640 "(a " | |
| 641 "(a a" | |

| 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, | |
