Make the new conf implementatoin bug-compatible with the old one.
Actually, it's a feature that it goes looking at environment
variables. It's just a pity that it's at the cost of the error
checking... I'll see if I can come up with a better interface for
this.
Fix from main trunk, 2000-10-16 15:08 ben:
Always return a value.
After some messing around this seems to work but needs
a few more tests. Working out the syntax for sk_set_cmp_func()
(cast it to a function that itself returns a function pointer)
was painful :-(
Needs some testing to see what other compilers think of this
syntax.
Also needs similar stuff for ASN1_SET_OF etc etc.
There's no trace of it being implemented and it doesn't seem to have been
intended given that it is prototyped with a BIO yet there was a BIO-
specific version added in at the same time.
"Jan Mikkelsen" <janm@transactionsite.com> correctly states that the
OpenSSL header files have #include's and extern "C"'s in an incorrect
order. Thusly fixed.
the result.
I have retained the old behavior of the CONF_* functions, and have
added a more "object oriented" interface through NCONF_* functions
(New CONF, you see :-)), working the same way as, for example, the
BIO interface. Really, the CONF_* are rewritten so they use the
NCONF_* functions internally.
In addition to that, I've split the old conf.c code into two files,
conf_def.c and conf_api.c. conf_def.c contains the default config
object that reads a configuration file the standard OpenSSL way, as
well as configuration file with Win32 registry file syntax (I'm not
sure I got that one right). conf_api.c provides an API to build other
configuration file readers around (can you see a configuraion file in
XML? I can :-)).
Finally, I've changed the name conf_lcl.h to conf_def.h, since it's
made specifically for that "class" and none others.
seemed like a good idea at the time... several hours later it was rather
obvious that these are used all over the place making the changes rather
extensive.
script, translates function codes better and doesn't need the K&R function
prototypes to work (NB. the K&R prototypes can't be wiped just yet: they are
still needed by the DEF generator...). I also ran the script with the -rewrite
option to update all the header and source files.
