Version 1.8.0 (25 Oct 2016)
Daniel Stenberg (25 Oct 2016)
- RELEASE-NOTES: adjusted for 1.8.0
Kamil Dudka (20 Oct 2016)
- Revert "aes: the init function fails when OpenSSL has AES support"
This partially reverts commit f4f2298ef3635acd031cc2ee0e71026cdcda5864
because it caused the compatibility code to call initialization routines
redundantly, leading to memory leakage with OpenSSL 1.1 and broken curl
test-suite in Fedora:
88 bytes in 1 blocks are definitely lost in loss record 5 of 8
at 0x4C2DB8D: malloc (vg_replace_malloc.c:299)
by 0x72C607D: CRYPTO_zalloc (mem.c:100)
by 0x72A2480: EVP_CIPHER_meth_new (cmeth_lib.c:18)
by 0x4E5A550: make_ctr_evp.isra.0 (openssl.c:407)

Fixes #74

- Revert "travis: Test mbedtls too"
This reverts commit 3e6de50a24815e72ec5597947f1831f6083b7da8.
Travis doesn't seem to support the mbedtls-dev package
- maketgz: support "only" to only update version number locally
and fix the date output locale
- configure: make the --with-* options override the OpenSSL default
... previously it would default to OpenSSL even with the --with-[crypto]
options used unless you specificly disabled OpenSSL. Now, enabling another
backend will automatically disable OpenSSL if the other one is found.

Basic dockerised test suite.
This introduces a test suite for libssh2. It runs OpenSSH in a Docker
container because that works well on Windows (via docker-machine) as
well as Linux. Presumably it works on Mac too with docker-machine, but
I've not tested that.
Because the test suite is docker-machine aware, you can also run it
against a cloud provider, for more realistic network testing, by setting
your cloud provider as your active docker machine. The Appveyor CI setup
in this commit does that because Appveyor doesn't support docker
locally.

Fix MSVC 14 compilation errors
For _MSC_VER == 1900 these macros are not needed and create problems:
1>C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt\stdio.h(1925): warning C4005: 'snprintf': macro redefinition (compiling source file libssh2-files\src\mac.c)
1> \win32\libssh2_config.h(27): note: see previous definition of 'snprintf' (compiling source file libssh2-files\src\mac.c)
1>C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt\stdio.h(1927): fatal error C1189: #error: Macro definition of snprintf conflicts with Standard Library function declaration (compiling source file libssh2-files\src\mac.c)

_libssh2_channel_open: speeling error fixed in channel error message
Alexander Lamaison (15 Mar 2016)
- Link with crypt32.lib on Windows.
Makes linking with static OpenSSL work again. Although it's not
required for dynamic OpenSSL, it does no harm.
Fixes #98.
- [Craig A. Berry brought this change]
Tweak VMS help file building.
Primarily this is handling cases where top-level files moved into
the docs/ directory. I also corrected a typo and removed the
claim that libssh2 is public domain.
- [Craig A. Berry brought this change]
Build with standard stat structure on VMS.
This gets us large file support, is available on any VMS release
in the last decade and more, and gives stat other modern features
such as 64-bit ino_t.
- [Craig A. Berry brought this change]
Update vms/libssh2_config.h.
VMS does have stdlib.h, gettimeofday(), and OpenSSL. The latter
is appropriate to hard-wire in the configuration because it's
installed by default as part of the base operating system and
there is currently no libgcrypt port.
- [Craig A. Berry brought this change]
VMS can't use %zd for off_t format.
%z is a C99-ism that VMS doesn't currently have; even though the
compiler is C99-compliant, the library isn't quite. The off_t used
for the st_size element of the stat can be 32-bit or 64-bit, so
detect what we've got and pick a format accordingly.
- [Craig A. Berry brought this change]
Normalize line endings in libssh2_sftp_get_channel.3.
Somehow it got Windows-style CRLF endings so convert to just LF,
for consistency as well as not to confuse tools that will regard
the \r as content (e.g. the OpenVMS help librarian).

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
