Prototype for X509_check_host() has changed, detect this in configure.ac
ChangeLog addition:
2015-04-09 Aidan Kehoe <kehoea@parhasard.net>
* configure.ac:
If X509_check_host() is available, check the number of arguments
it takes. Don't use it if it takes any number of arguments other
than five. Also don't use it if <openssl/x509v3.h> does not
declare it, since if that is so there is no portable way to tell
how many arguments it should take, and so we would end up smashing
the stack.
* configure: Regenerate.
src/ChangeLog addition:
2015-04-09 Aidan Kehoe <kehoea@parhasard.net>
* tls.c:
#include <openssl/x509v3.h> for its prototype for
X509_check_host().
* tls.c (tls_open):
Pass the new fifth argument to X509_check_host().

| 26 | |
| 27 ;; Not yet dumped into XEmacs. | |
| 28 | |
| 29 ;; The idea behind magic variables is that you can specify arbitrary | |
| 30 ;; behavior to happen when setting or retrieving a variable's value. The | |
| 31 ;; purpose of this is to make it possible to cleanly provide support for | |
| 32 ;; obsolete variables (e.g. unread-command-event, which is obsolete for | |
| 33 ;; unread-command-events) and variable compatibility | |
| 34 ;; (e.g. suggest-key-bindings, the FSF equivalent of | |
| 35 ;; teach-extended-commands-p and teach-extended-commands-timeout). | |
| 36 | |
| 37 ;; There are a large number of functions pertaining to a variable's | |
| 38 ;; value: | |
| 39 | |
| 40 ;; boundp | |
| 41 ;; globally-boundp | |
| 42 ;; makunbound | |
| 43 ;; symbol-value | |
| 44 ;; set / setq | |
| 45 ;; default-boundp | |
| 46 ;; default-value | |
| 47 ;; set-default / setq-default | |
| 48 ;; make-variable-buffer-local | |
| 49 ;; make-local-variable | |
| 50 ;; kill-local-variable | |
| 51 ;; kill-console-local-variable | |
| 52 ;; symbol-value-in-buffer | |
| 53 ;; symbol-value-in-console | |
| 54 ;; local-variable-p / local-variable-if-set-p | |
| 55 | |
| 56 ;; Plus some "meta-functions": | |
| 57 | |
| 58 ;; defvaralias | |
| 59 ;; variable-alias | |
| 60 ;; indirect-variable | |
| 61 | |
| 62 ;; I wanted an implementation that: | |
| 63 | |
| 64 ;; -- would work with all the above functions, but (a) didn't require | |
| 65 ;; a separate handler for every function, and (b) would work OK | |
| 66 ;; even if more functions are added (e.g. `set-symbol-value-in-buffer' | |
| 67 ;; or `makunbound-default') or if more arguments are added to a | |
| 68 ;; function. | |
| 69 ;; -- avoided consing if at all possible. | |
| 70 ;; -- didn't slow down operations on non-magic variables (therefore, | |
| 71 ;; storing the magic information using `put' is ruled out). | |
| 72 ;; | |
| 73 | |
| 74 ;;; Code: | |
| 75 | |
| 76 ;; perhaps this should check whether the functions are bound, so that | |
| 77 ;; some handlers can be unspecified. That requires that all functions | |
| 78 ;; are defined before `define-magic-variable-handlers' is called, | |
| 79 ;; though. | |
| 80 | |
| 81 ;; perhaps there should be something that combines | |
| 82 ;; `define-magic-variable-handlers' with `defvaralias'. | |
