annotate src/print.c @ 5891:a0e751d6c3ad
Import the #'clear-string API from GNU, use it in tls.c
src/ChangeLog addition:
2015-04-18 Aidan Kehoe <kehoea@parhasard.net>
* sequence.c (Fclear_string): New, API from GNU. Zero a string's
contents, making sure the text is not kept around even when the
string's data is reallocated because of a changed character
length.
* sequence.c (syms_of_sequence): Make it available to Lisp.
* lisp.h: Make it available to C code.
* tls.c (nss_pk11_password): Use it.
* tls.c (gnutls_pk11_password): Use it.
* tls.c (openssl_password): Use it.
tests/ChangeLog addition:
2015-04-18 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test #'clear-string, just added. Unfortunately there's no way to
be certain from Lisp that the old password data has been erased
after realloc; it may be worth adding a test to tests.c, but
*we'll be reading memory we shouldn't be*, so that gives me pause.

628 /* Here we could safely return the canonicalized PRINTCHARFUN. | |
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, | |
651 only once. */ | |
