Memory Leaks

2002-04-29 Thread psatpathy




Hi,
 I am facing a memory leaks in my program. I am using
BN_new,BN_CTX_new,BN_mod_exp,BN_free and BN_CTX_free  OpenSSL functions in my
program only.  I am using "openssl-0.9.6b" libraries in Solaris 8. I am
attaching my code for your reference. Please let me know how can I come over
from memory leak.


With Regards,

Richard:

I would be happy to work on this with you if you give me some
direction on how you would like it to go.  

It seems to me that there is no reason that Configure could not
actually do the work of the .bat files for the Windows platforms
provided that the appropriate options were added to that Perl script.

Here you reversing patches that you had committed for 0.9.8-dev but
not for 0.9.7-stable ...

Hmm, I fixed those, but apparently only in the 0.9.7-stable branch.  I'll
merge those changes into the main branch...

util/mk1mf.pl doesn't look at the CFLAG or CFLAGS variables of MINFO.
Why is beyond me.  You are currently required to call it (i.e. hack
ms\do_*.bat) with the same arguments as you used for Configure.
Unfortunately, Configure and the scripts in util/ aren't entirely in
sync...

I don't work on Windows right now, so I could do some changes, but
they'd be pure guesswork.  I've planned to try to unify the Windows/MSDOS
scripts with Configure so things work a little more like on Unix, but
haven't had time yet.

Yes, this is a mess...

I think the FAQ entry is enough. If you set a new default then you can
surprise many small scripts and their users. The flag -nameopt is a good
solution.

The only problem for the future is the support of this flag in all the
other tools (especially ca and req have problems with their option
-subj).

I found a small problem with -nameopt RFC2253:

The X509v3 Authority Key Identifier doesn't use -nameopt for DirName. Is
this DN stored as a string?
