I think you left out keychain_impl.h :-)

We don't (AFAIK) have a realm-string parsing API.
I looked at the Internet API before settling on Generic passwords;
it wasn't clear to me that we could use "svn" as a protocol (it's
not one of the enumerated SecProtocolType values). Maybe you can
shed some light on that.

I had the same question about the original patch. I haven't tried to
store cert passwords in the keychain yet. I will commit the simple
work first and then work through the SSL case.
I think a few things remain, though:
1.) The Windows password encryption/decryption was implemented
inside the simple provider. I made some changes a little
r16602 | mbk | 2005-10-08 21:40:29 -0400 (Sat, 08 Oct 2005) | 19 lines
Rework the simple auth provider internals to allow for more control over
the storage of the password component of the credentials (in preparation
for adding Mac OS X Keychain support).
So my implementation added a third simple_provider ("darwin") that
used the same helper system to drive the config-file storage of the
username. This enabled me to call SecKeychainFindGenericPassword()
only once, using the username from the config-file as the key,
rather than two calls, one with a "username" prompt and one
with a "password" prompt.
Perhaps this wasn't the best strategy; perhaps I should have made
a first-class provider as you have done, and stored the username
and password as separate entries. That might be more consistent
with other OS X application behaviour.
I'm not sentimentially attached to those changes, and I'll revert
them if they serve no purpose, but I'd like to make sure
that we're moving in the right direction when I do. Do you have
an opinion on this?
+if test "$enable_keychain" = "yes"; then
+ SVN_KEYCHAIN_LIBS="-framework Security -framework CoreFoundation -framework CoreServices"
+ AC_DEFINE([SVN_HAVE_KEYCHAIN_SERVICES], , [Is Mac OS KeyChain support enabled?])
Yay, configury! But won't this break the build on non-OS-X systems, or
at least systems whose ld can't ignore -framework?
And is it sufficient?
I had code like
#if (MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_2)
#define SVN_HAVE_KEYCHAIN_SERVICES 1
to test for the presence of the API. We could do this test at
configure-time. But is this the right test?
3.) Support for --non-interactive.
Is surrounding the SecKeychain calls with calls to
SecKeychainSetUserInteractionAllowed(FALSE) and then
SecKeychainSetUserInteractionAllowed(TRUE) the right way to implement
--non-interactive? Could it be that easy?
