Despite we announced the CMake support in libssh2-1.6.0 release notes,
the files required by the CMake build system were not included in the
release tarballs. Hence, the only way to use CMake for build was the
upstream git repository.
This commit makes CMake actually supported in the release tarballs.
Inspired by Bob Kast's reports, this commit enables the compilation
of libssh2 with WinCNG using the generated Visual Studio project files.
This commit adds WinCNG support to parts of the existing Win32 build
infrastructure, until new build systems, like pre-defined VS project
files or CMake files may be added.
This commit and b20bfeb3e5 raise one
question: How to handle build systems, like VS project files, that
need to include all source files regardless of the desired target,
including all supported crypto backends? For now the mentioned commit
added a check for LIBSSH2_OPENSSL to openssl.c and with this commit
the supported crypto backends are hardcoded within Makefile.am.
Commit d512b25f69 added automake
conditionals to Makefile.inc but since Makefile.inc is included
from Makefile for all other build systems that does not work.
This commit instead adds Makefile.OpenSSL.inc and Makefile.libgcrypt.inc
and moves the automake conditional to its proper place, src/Makefile.am.
The automake conditional includes the correct Makefile.$name.inc per
the crypto library selection/detection done by configure.
All non-autotools build system files in libssh2 are hardcoded to use
OpenSSL and do not get a conditional but at least there is some reuse
because they can all include the new Makefile.OpenSSL.inc.
Examples are built by default. Any of the following options on the
configure command line will skip building them:
--disable-examples-build
--enable-examples-build=no
--enable-examples-build=false
First, win32/msvcproj.{head,foot} are now committed with CRLF line endings,
and .gitattributes specifies that these should not be changed on checkout or
commit. These are win32 files so it makes sense to store them with native
line endings.
Second, the rules for generating libssh2.dsp and libssh2.vcproj are changed
so that the full file contents passes through awk, which strips all CR and
then prints each line with one CRLF line ending. Stripping CR is important
to avoid CRCRLF in case the input already comes with CRLF.
the making of the release archive.
Added 'maketgz' as a script to build release archives with, including automated
snapshots or whatever. It updates the defines in include/libssh2.h.
configure now extracts the version number from the include/libssh2.h header in
the source tree instead of using it fixed set in the script (to remove the
need for regenerating the configure script when we run maketgz).
Makefile.am now has a dist-hook that puts ".dist" files in the release tree
instead of the file without the .dist extension, so that we can easily add
modified files in release archives. Like maketgz.
blocking way. The channel code is now responsible for enabling/disabling
blocking status and to work with it.
I've also modified indenting and fixed compiler warnings at places, and
added a bunch of new examples in example/simple that I've used to verify that
the code still runs like before.
libssh2_channel_{read|write}nb_ex() and libssh2_sftp_{read|write}nb() are the
four new functions that supposedly work non-blocking.
