* cmake: drop posix dependency from pcre* detectionJan Palus2022-07-072-5/+4
| | | | | since f585b12 neither PCRE nor PCRE2 backends rely on POSIX regex, so reflect it in library detection logic
* sha256: support dynamically loaded opensslEdward Thomson2022-04-041-0/+8
|
* sha: support Win32 for SHA256Edward Thomson2022-03-231-0/+2
| | | | | Adding SHA256 support prompted an overdue refactoring of some of the unnecessary complexity around the CNG/CryptoAPI abstraction.
* sha: support OpenSSL for SHA256Edward Thomson2022-03-231-7/+9

* sha: support CommonCrypto for SHA256Edward Thomson2022-03-231-1/+15
|
* sha: add sha256 algorithmEdward Thomson2022-03-231-1/+13
| | | | | Add support for a SHA256 hash algorithm, and add the "builtin" SHA256 hash engine (from RFC 6234).
* sha1: remove generic implementationEdward Thomson2022-03-231-1/+1
| | | | | | Remove the "generic" implementation; it should never be used; it only existed for a no-dependencies configuration, and our bundled sha1dc satisfies that requirement _and_ is correct.

* refactor: make util an object libraryEdward Thomson2022-02-221-3/+0
| | | | | | | | | | Instead of simply including the utility files directly, make them a cmake object library for easy reusability between other projects within libgit2. Now the top-level `src` is responsible for platform selection, while the next-level `libgit2` and `util` configurations are responsible for identifying what objects they include.
* cmake: Fix package name for system http-parserMichał Górny2022-02-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix building against system http-parser library by fixing the find_package() argument. It seems to have been accidentally changed from HTTPParser to HTTP_Parser in de178d36f, effectively making the build against system library fail to find it: ``` CMake Warning at cmake/SelectHTTPParser.cmake:3 (find_package): By not providing "FindHTTP_Parser.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "HTTP_Parser", but CMake did not find one. Could not find a package configuration file provided by "HTTP_Parser" with any of the following names: HTTP_ParserConfig.cmake http_parser-config.cmake Add the installation prefix of "HTTP_Parser" to CMAKE_PREFIX_PATH or set "HTTP_Parser_DIR" to a directory containing one of the above files. If "HTTP_Parser" provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): src/CMakeLists.txt:97 (include) CMake Error at cmake/SelectHTTPParser.cmake:11 (message): http-parser support was requested but not found Call Stack (most recent call first): src/CMakeLists.txt:97 (include) ```

| * Disabling setting `CMAKE_FIND_LIBRARY_SUFFIXES` on Apple platforms.Miguel Arroz2021-12-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | On macOS, since Big Sur, the libraries were moved to a cache. The SDK comes with stubs in the SDK (`/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk/usr/lib/` or whatever SDK version one has installed) where most have the `.tbd` suffix (although some still are `.a`). Forcing `CMAKE_FIND_LIBRARY_SUFFIXES` on Apple platforms broke building, unless one has copies of the libraries installed elsewhere (like Brew), as many libraries (like `iconv` or `pcre`) are not found. This fix disables setting the `CMAKE_FIND_LIBRARY_SUFFIXES` to `.a` if the platform is `APPLE` when building static libs.

* cmake: use PROJECT_SOURCE_DIR of CMAKE_SOURCE_DIRJosh Junon2021-12-235-11/+11
| | | | | | | | | | | | | | | | | | | | | | | Also applies to *_BINARY_DIR. This effectively reverts 84083dcc8bd41332ccac9d7b537f3e254d79011c, which broke all users of libgit2 that use it as a CMake subdirectory (via `add_subdirectory()`). This is because CMAKE_SOURCE_DIR refers to the root-most CMake directory, which in the case of `add_subdirectory()` is a parent project to libgit2 and thus the paths don't make any sense to the configuration files. Corollary, CMAKE_SOURCE_DIR only makes sense if the CMake project is always the root project - which can rarely be guaranteed. In all honesty, CMake should deprecate and eventually remove CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR. It's been the source of headaches and confusion for years, they're rarely useful over CMAKE_CURRENT_(SOURCE|BINARY)_DIR or PROJECT_(SOURCE|BINARY)_DIR, and they cause a lot of confusing configuration and source code layouts to boot. Any time they are used, they break `add_subdirectory()` almost 100% of the time, cause confusing error messages, and hide subtle bugs.

| | | | | | | | Threading can now be disabled with `USE_THREADS=OFF` instead of `THREADSAFE=OFF` to better support the other cmake semantics. Nanosecond support is the default _if_ we can detect it. This should be our default always - like threads - and people can opt out explicitly.

* openssl: dynamically load libssl and symbols (optionally)Edward Thomson2021-08-241-0/+4
| | | | | | | | | | Provide an interface around OpenSSL to dynamically load the libraries and symbols, so that users can distribute a libgit2 library that is not linked directly against OpenSSL. This enables users to target multiple distributions with a single binary. This mechanism is optional and disabled by default. Configure cmake with -DUSE_HTTPS=OpenSSL-Dynamic to use it.

* cmake: remove CheckPrototypeDefinition modulePatrick Steinhardt2020-07-122-125/+0
| | | | | | | | | In the past, we've imported the CheckPrototypeDefinition into our own module directory as it wasn't yet available in all supported CMake versions. Now that we require at least CMake v3.5, we don't need to bundle it anymore as it's included with the distribution already. Let's drop the included modules and always use upstream's version.
* cmake: move modules into the "cmake/" top level dirPatrick Steinhardt2020-06-0121-0/+0
| | | | | | | | Our custom CMake module currently live in "cmake/Modules". As the "cmake/" directory doesn't contain anything except the "Modules" directory, it doesn't really make sense to have the additional intermediate directory. So let's instead move the modules one level up into the "cmake/" top level directory.
* cmake: Sort source files for reproducible buildspks/cmake-sort-reproducible-buildsPatrick Steinhardt2020-05-151-0/+2
| | | | | | | | | | | We currently use `FILE(GLOB ...)` in most places to find source and header files. This is problematic in that the order of files returned depends on the operating system's directory iteration order and may thus not be deterministic. As a result, we link object files in unspecified order, which may cause the linker to emit different code across runs. Fix this issue by sorting all code used as input to the libgit2 library to improve the reliability of reproducible builds.
* cmake: streamline backend detectionPatrick Steinhardt2020-04-013-86/+61
| | | | | | | We're currently doing unnecessary work to auto-detect backends even if the functionality is disabled altogether. Let's fix this by removing the extraneous FOO_BACKEND variables, instead letting auto-detection modify the variable itself.
* cmake: use install directories provided via GNUInstallDirsPatrick Steinhardt2020-03-141-5/+3
| | | | | | | | | | | | | | | | | | | | | | | We currently hand-code logic to configure where to install our artifacts via the `LIB_INSTALL_DIR`, `INCLUDE_INSTALL_DIR` and `BIN_INSTALL_DIR` variables. This is reinventing the wheel, as CMake already provide a way to do that via `CMAKE_INSTALL_<DIR>` paths, e.g. `CMAKE_INSTALL_LIB`. This requires users of libgit2 to know about the discrepancy and will require special hacks for any build systems that handle these variables in an automated way. One such example is Gentoo Linux, which sets up these paths in both the cmake and cmake-utils eclass. So let's stop doing that: the GNUInstallDirs module handles it in a better way for us, especially so as the actual values are dependent on CMAKE_INSTALL_PREFIX. This commit removes our own set of variables and instead refers users to use the standard ones. As a second benefit, this commit also fixes our pkgconfig generation to use the GNUInstallDirs module. We had a bug there where we ignored the CMAKE_INSTALL_PREFIX when configuring the libdir and includedir keys, so if libdir was set to "lib64", then libdir would be an invalid path. With GNUInstallDirs, we can now use `CMAKE_INSTALL_FULL_LIBDIR`, which handles the prefix for us.

| * cmake: sanitize boolean options passed by userPatrick Steinhardt2020-02-244-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with our conversions to mix backend-autodetection and selection into a single variable (USE_GSSAPI, USE_HTTPS, USE_SHA1), we have introduced a simple STREQUAL to check for "ON", which indicates that the user wants us to auto-detect available backends and pick any one that's available. This behaviour deviates from previous behaviour, as passing a value like "yes", "on" or "true" will in fact be treated like a backend name and result in autodetection failure. Fix the issue by introducing a new function `SanitizeBool`. Given a variable that may hold a boolean value, the function will sanitize that variable to hold either "ON" or "OFF". In case it is not a recognized boolean, we will just keep the value as-is. This fixes the above described issue.

|/ | | | | | | | Remove using custom PKG_BUILD_PREFIu, PKG_BUILD_LIBDIR and PKG_BUILD_INCLUDEDIR variables. Use cmake CMAKE_INSTALL_PREFIX, LIB_INSTALL_DIR, INCLUDE_INSTALL_DIR instead. This patch fixes install libgit2.pc file in correct location and simpifies cmake module.
* gssapi: show information about disabled GSSAPIEdward Thomson2020-01-241-1/+1

|/ | | | | | | | LIBRARIES is the (absolute?) path to the library. LDFLAGS is the full linker stanza to correctly link with this lib. By passing LIBRARIES as LIBGIT_LIBS, the linker ends up with the absolute path for the SDK'ed version of CoreFoundation (which doesn't exist), instead of the familiar `-framework CoreFoundation`.
