- fix indentation errors.
- reformat `cmake/FindmbedTLS.cmake`
- replace a macro with a variable in `example/sftp_RW_nonblock.c`.
- delete macOS macro `_DARWIN_USE_64_BIT_INODE` from the
OS/400 config header, `os400/libssh2_config.h`.
- fix other minor nits.
Closes#983
- use `gman` alias if present. This makes it work when the correct `man`
command is provided via `brew` on macOS.
- move CMake attempts to detect tools necessary to run `mansyntax.sh`
into the script itself.
- delete CMake TODO to move more test logic into CMake. This would make
it CMake-specific and require maintaining it separately for each build
tool. Just use our external script when a POSIX shell is available.
Closes#982
Move `libssh2_config.h` generation and setting `-DHAVE_CONFIG_H` to
the root `CMakeFile.txt`.
Also move symbol hiding setup there. It needs to be done before
generating the config file for `LIBSSH2_API` value to be set in it.
After this change the `HIDE_SYMBOLS` setting is accepted without an
annoying CMake warning when not actually building a shared libssh2 lib.
Closes#981
Drop checks from Windows builds and enable it based on `WIN32`.
This saves detection time and also makes 3rd party builds simpler.
Also:
- delete `HAVE_DISABLED_NONBLOCKING`, that we used in build tools to
explicitly disable an explicit `#error` in `session.c`.
- replace existing `WSAEWOULDBLOCK` check for Windows support with
`WIN32`. Cleaner with the same result.

Make the public `libssh2_base64_decode()` a wrapper for that.
Bump up length sizes in callers.
Also fix output size calculation to first divide then multiply.
Closes#978
- rename tests to have more succint names and a more useful natural
order.
- rename `simple` and `ssh2` in tests to have the `test_` prefix.
This avoids a name collisions with `ssh2` in examples.
- cmake: drop the `example-` prefix for generated examples.
Bringing their names in sync with other build tools, like autotools.
- move common auth test code into the fixture and simplify tests by
using that.
- move feature guards from CMake to preprocessor for auth tests.
Now it works with all build tools and it's easier to keep it in sync
with the lib itself.
For this we need to include `libssh2_priv.h` in tests, which in turn
needs tweaking on the trick we use to suppress extra MSVS warnings
when building tests and examples.
- move mbedTLS blocklist for crypto tests from CMake to the test
fixture.
- add ed25519 hostkey tests to `test_hostkey` and `test_hostkey_hash`.
- add shell script to regenerate all test keys used for our tests.
- alpha-sort tests.
- rename `signed_*` keys to begin with `key` like the rest of the keys
do.
- whitespace fixes.
Closes#969

- doesn't need manual bumps.
- is ahead of stable and should be stable enough for our purpose.
- slim is saving resources.
Closes#971
Skip testing unixy methods on Windows and vice versa.
I continue to assume that CMake doesn't define `WIN32` with Cygwin
(as Cygwin doesn't define `_WIN32`/`WIN32` for C), though I haven't
tested this.
Closes#970
A new flag named `LIBSSH2_FLAG_QUOTE_PATHS` has been added, to make
libssh2 not quote file paths sent to the remote's scp subsystem. Some
custom ssh daemons cannot handle quoted paths, and this makes this flag
useful.

- use the complete filename of test sources in the input list.
- build all tests with the ability to access libssh2 internals.
This is necessary for `test_keyboard_interactive_auth_info_request`
now and might be necessary for others in the future, e.g. to avoid
the depreacted public base64 decoding API.
- move `test_keyboard_interactive_auth_info_request` into the main
test build loop.
- move `simple` into the main test build loop too.
- build `ssh2` also in static mode.
- cleanup the way we detect and enable gcov.
- fix indentation.
Closes#967
- fix skip auth if `userauthlist` is NULL.
Closes#836 (Reported-by: @sudipm-mukherjee on github)
- fix most silenced `checksrc` warnings.
- sync examples/tests code between each other.
(output messages, error handling, declaration order, comments)
- stop including unnecessary headers.
- always deinitialize in case of error.
- drop some redundant variables.
- add error handling where missing.
- show more error codes.
- switch `perror()` to `fprintf()`.
- fix some `printf()`s to be `fprintf()`.
- formatting.

* os400: support QADRT development files in a non-standard directory
This enables the possibility to compile libssh2 even if the ascii
runtime development files are not installed system-wide.
* userauth_kbd_packet: fix a pointer target type mismatch.
A temporary variable matching the parameter type is used before copying
to the real target and checking for overflow (that should not occur!).
* os400qc3: move and fix big number procedures
A bug added by a previous code style cleaning is fixed.
_libssh2_random() now checks and return the success status.
* os400qc3: fix cipher definition block lengths
They were wrongly set to the key size.
* Diffie-Hellman min/max modulus sizes are dependent of crypto-backend
In particular, os400qc3 limits the maximum group size to 2048-bits.
Move definitions of these parameters to crypto backend header files.
* kex: return an error if Diffie-Hellman key pair generation fails
* os400: add an ascii assert.h header file
* os400qc3: implement RSA SHA2 256/512
Before this patch, libssh2 sent hardcoded `LIBSSH2_SFTP_ATTRIBUTES`
struct on handle open. This can be problematic on some special OS,
where the file size should be known on new file creation. I added
two new functions to resolve this issue.
Patch-by: @vajdaakos on github via #506
Changes compared to #506:
- drop attr size fixup in favour of #946.
- move `memcpy()` under the state where we need it.
- bump filename length type to `size_t`.
- fix filenames in documentation and other nits.

Implement picky warnings with clang in autotools. Extend picky gcc
warnings, sync them between build tools and compilers and greatly
speed up detection in CMake.
- autotools: enable clang compiler warnings with `--enable-debug`.
- autotools: enable more gcc compiler warnings with `--enable-debug`.
- autotools/cmake: sync compiler warning options between gcc and clang.
- sync compiler warning options between autotools and cmake.
- cmake: reduce option-checks to speed up the detection phase.
Bring them down to 3 (from 35). Leaving some checks to keep the
CMake logic alive and for an easy way to add new options.
clang 3.0 (2011-11-29) and gcc 2.95 (1999-07-31) now required.
- autotools logic copied from curl, with these differences:
- delete `-Wimplicit-fallthrough=4` due to a false positive.
- reduce `-Wformat-truncation=2` to `1` due to a false positive.
- simplify MinGW detection for `-Wno-pedantic-ms-format`.
- cmake: show enabled picky compiler options (like autotools).
- cmake: do compile `tests/simple.c` and `tests/ssh2.c`.
- fix new compiler warnings.
- `tests/CMakeLists.txt`: fix indentation.
Original source of autotools logic:
- a8fbdb461c/acinclude.m4
- a8fbdb461c/m4/curl-compilers.m4
Notice that the autotools implementation considers Apple clang as
legacy clang 3.7. CMake detection works more accurately, at the same
time more error-prone and difficult to update due to the sparsely
documented nature of Apple clang option evolution.
Closes#952
After recent build changes, 3rd party build that took the list of
C source to compile them as-is, stopped working as expected, due to
`blowfish.c` and crypto-backend C sources no longer expected to compile
separately but via `bcrypt_pbkdf.c` and `crypto.c`, respectively.
This patch ensures that compiling these files directly result in an
empty object instead of redundant code and duplicated symbols.
Also:
- add a compile-time error if none of the supported crypto backends
are enabled.
- fix `libssh2_crypto_engine()` for wolfSSL and os400qc3.
Rearrange code to avoid a hard-to-find copy of crypto-backend
selection guards.

Prerequisite for #947, #506.
Also improve readability a bit and link to SFTP specs. Delete comment

Closes#216Closes#632Closes#945
Caveat: When building `--enable-static` and `--enable-shared` at the
same time, the compiled Windows resource is also included in the
static library. This appears to be an autotools limitation, with no
way to have different input lists (or different custom options) for
shared and static libraries, even though it builds them separately.
The workaround is to build static libraries in a separate
`./configure` + `make` pass.
Closes#944
- introduce `src/crypto.c` as an umbrella source that does nothing else
than include the selected crypto backend source. Moving this job from
the built-tool to the C preprocessor.
- this allows dropping the various techniques to pick the correct crypto
backend sources in autotools, CMake and other build method. Including
the per-backend `Makefile.<crypto-backend>.inc` makefiles.
- copy a trick from curl and instead of maintaining duplicate source
lists for CMake, convert the GNU Makefile kept for autotools
automatically. Do this in `docs`, `examples` and `src`.
Ref: dfabe8bca2/CMakeLists.txt (L1399-L1413)
Also fixes missing `libssh2_setup.h` from `src/CMakeFiles.txt` after
59666e03f0.
- move `Makefile.inc` from root to `src`.
- reformat `src/Makefile.inc` to list each source in separate lines,
re-align the continuation character and sort the lists alphabetically.
- update `docs/HACKING-CRYPTO` accordingly.
- autotools: update the way we add crypto-backends to `LIBS`.
- delete old CSV headers, indent, and merge two lines in
`docs/Makefile.am` and `src/Makefile.am`.
- add `libssh2.pc` to `.gitignore`, while there.
Closes#941
- implement symbol hiding on non-Windows platforms.
The essence of the detection logic was copied from:
dfabe8bca2/CMake/CurlSymbolHiding.cmake
Then simplified and shortened. This method doesn't require a recent
CMake version, nor an external, auto-generated C header.
Move `configure_file()` after `set(LIBSSH2_API ...)`, for the config
file to pick up `LIBSSH2_API`s value.
Closes#602
- add CMake option `HIDE_SYMBOLS`.
This setting means to hide non-public functions from the libssh2
dynamic library when set to `ON`. The default.
When set to `OFF`, make all non-static/internal functions visible
in the dynamic library.
This setting requires `BUILD_SHARED_LIBS=ON`.
- honor this setting on Windows.
By setting the `LIBSSH2_EXPORTS` manual macro again, and stop
recognizing the automatic CMake macro for this purpose:
`libssh2_shared_EXPORT`.
Closes#939
- include `blowfish.c` into `bcrypt_pbkdf.c`, instead of
compiling it as a distinct object.
- make low-level blowfish functions static. This prevents this symbols
to pollute the public namespace of libssh2. It also allows the
compiler to inline these functions.
- integrate `blf.h` header into `bcrypt_pbkdf.c` as well.
- use `_DEBUG_BLOWFISH` instead of `#if 0`.
- fix `_DEBUG_BLOWFISH` compiler warnings and other nits.
- `#undef` `inline` before redefining it in `libssh2_priv.h`.
(copied from `blowfish.c`)
- delete unused `inline` redefinitions from `blowfish.c`.
- disable unused low-level blowfish functions.
- formatting, header order.
Closes#938
- fix to use `LIBSSH2DEBUG` macro to set the debug flag.
(was `DEBUGBUILD`, a curl-specific macro)
- use manifest constants instead of literals
- change language to neutral
Closes#937
- drop unnecessary `WIN32`-specific branches.
- add `static`.
- sync header inclusion order.
- sync some common code between examples/tests.
