libssh2 used to explicitly check for libgcrypt and default to OpenSSL.
Now all possible crypto libraries are checked for explicitly, making
the addition of further crypto libraries both simpler and cleaner.
Added crypto.h that is the unified header to include when using crypto
functionality. It should be the only header that needs to adapt to the
underlying crypto library in use. It provides the set of prototypes that
are library agnostic.
I'll introduce a new internal function set named
_libssh2_store_u32
_libssh2_store_u64
_libssh2_store_str
That can be used all through the library to build binary outgoing
packets. Using these instead of the current approach removes
hundreds of lines from the library while at the same time greatly
enhances readability. I've not yet fully converted everything to
use these functions.
I've converted LOTS of 'unsigned long' to 'size_t' where
data/string lengths are dealt with internally. This is The Right
Thing and it will help us make the transition to our
size_t-polished API later on as well.
I'm removing the PACKET_* error codes. They were originally
introduced as a set of separate error codes from the transport
layer, but having its own set of errors turned out to be very
awkward and they were then converted into a set of #defines that
simply maps them to the global libssh2 error codes instead. Now,
I'l take the next logical step and simply replace the PACKET_*
defines with the actual LIBSSH2_ERROR_* defines. It will increase
readability and decrease confusion.
I also separated packet stuff into its own packet.h header file.
Makefile changes to generate MSVS project files
- I integrated the libssh2_lib.dsp and libssh2_dll.dsp into a single
libssh2.dsp with different targets for lib vs dll
- Since I run Visual Studio 2008 with VC++9 I did not do vcproj files since
I would have newer vc8proj.head|foot than what others will be running
- My patch only has changes to Makefile.am's. I noticed that Makefile.in's
are included in the daily snapshots but they should be generated from the
.am's
- The 3 new files are msvcproj.head and msvcproj.foot for the beginning and
ending of the dsp file, and a new Makefile.inc that will have the source and
header file names. NOTE: All new source files will need to be added to
Makefile.inc and NOT Makefile.am now.
- I moved the win32 dir before the include dir
- I modified the dsw file so it points to the new libssh2.dsp project file
