522f3e4b	2018-02-16T10:50:54	CMakeLists: increase strict aliasing level to 3 The strict aliasing rules disallow dereferencing the pointer to a variable of a certain type as another type, which is frequently used e.g. when casting structs to their base type. We currently have the warning level for strict aliasing rules set to `2`, which is described by gcc(1) as being "Aggressive, quick, not too precise." And in fact, we experience quite a lot of warnings when doing a release build due to that. GCC provides multiple levels, where higher levels are more accurate, but also slower due to the additional analysis required. Still, we want to have warning level 3 instead of 2 to avoid the current warnings we have in the Travis CI release builds. As this is the default warning level when no level is passed to `-Wstrict-aliasing`, we can just remove the level and use that default.

6416b91f	2018-02-02T17:58:44	cmake: enable policy CMP0042 Enable CMake policy CMP0042, if supported: > CMake 2.8.12 and newer has support for using ``@rpath`` in a target's > install name. This was enabled by setting the target property > ``MACOSX_RPATH``. The ``@rpath`` in an install name is a more > flexible and powerful mechanism than ``@executable_path`` or > ``@loader_path`` for locating shared libraries.
94aa36ef	2018-02-02T17:56:15	cmake: test for CMP0051 instead of version check We can use policy checks to see if a policy exists in cmake, like CMP0051, instead of relying on the version.
6d452600	2018-01-10T11:52:15	cmake: use a FEATURE_SUMMARY call compatible with 3.0.2 When we print features, we make an effort to support all the way back to pre-3.0. However, in the code for versions from 3 onward we call `FEATURE_SUMMARY` with multiple kinds of elements to print in the same line. This is only supported in CMake 3.1 and later, making the rather popular CMake 3.0.2 unable to build the library. Use a single kind of element per invocation. This means we need to provide a "description" text, which CMake provides for us if provide multiple kinds of elements.

85e40bbf	2018-01-07T12:51:26	cmake: move the rule to find static archives close to building clar If we're building static libraries, we want to use that for building our clar binary. This is done in 49551254 (2017-09-22; cmake: use static dependencies when building static libgit2) but that commit included the rule too early, making it affect the search for iconv, meaning we did not find it when we were building a static libgit2. Move the rule to just before building clar, after we've included the rules for building the library itself. This lets us find and link to the dynamic libiconv.
70aa6146	2017-12-05T08:48:31	cmake: allow explicitly choosing SHA1 backend Right now, if SHA1DC is disabled, the SHA1 backend is mostly chosen based on which system libgit2 is being compiled on and which libraries have been found. To give developers and distributions more choice, enable them to request specific backends by passing in a `-DSHA1_BACKEND=<BACKEND>` option instead. This completely replaces the previous auto-selection.
e7495ce6	2017-12-05T08:47:57	cmake: default to using SHA1DC Upstream git.git has changed their default SHA1 implementation to the collision-detection algorithm SHA1DC in commit e6b07da27 (Makefile: make DC_SHA1 the default, 2017-03-17). To match upstream, align ourselves and switch over to SHA1DC by default.
bbb213c1	2017-11-11T13:19:24	cmake: let USE_ICONV be optional on macOS Instead of forcing iconv support on macOS (by forcing `USE_ICONV` on), honor the `USE_ICONV` option only on macOS. Although macOS includes iconv by default, some macOS users may have a deficient installation for some reason and they should be provided a workaround to use libgit2 even in this situation. iconv support is now disabled entirely on non-macOS platforms. No other platform supports core.precomposeunicode, and iconv should never be linked.
a0b0b808	2017-11-11T14:03:14	cmake: Allow user to select bundled zlib Under some circumstances the installed / system version of zlib may not be desirable due to being too old or buggy. This patch adds the option `USE_BUNDLED_ZLIB` that will cause the bundled version of zlib to be used. We may also want to add similar functionality to allow the user to select other bundled 3rd-party dependencies instead of using the system versions. /cc @pks-t @ethomson

fdd06874	2017-08-09T21:35:53	cmake: use FeatureSummary to display which features we end up using
4da74c83	2017-10-20T07:29:17	cmake: use project-relative binary and source directories Due to our split of CMake files into multiple modules, we had to replace some uses of the `${CMAKE_CURRENT_SOURCE_DIR}` and `${CMAKE_CURRENT_BINARY_DIR}` variables and replace them with `${CMAKE_SOURCE_DIR}` and `${CMAKE_BINARY_DIR}`. This enabled us to still be able to refer to top-level files when defining build instructions inside of a subdirectory. When replacing all variables, it was assumed that the absolute set of variables is always relative to the current project. But in fact, this is not the case, as these variables always point to the source and binary directory as given by the top-levl project. So the change actually broke the ability to include libgit2 directly as a subproject, as source files cannot be found anymore. Fix this by instead using project-specific source and binary directories with `${libgit2_SOURCE_DIR}` and `${libgit2_BINARY_DIR}`.

With CMake 3.0.2, the build was failing with CMake Error at CMakeLists.txt:18 (CMAKE_POLICY): Policy "CMP0051" is not known to this version of CMake. This patch makes it work.
8ac8c78c	2017-10-09T15:15:08	Merge pull request #4356 from pks-t/pks/static-clar cmake: use static dependencies when building static libgit2
49551254	2017-09-22T09:34:37	cmake: use static dependencies when building static libgit2 CMake allows us to build a static library by simply setting the variable `BUILD_SHARED_LIBS` to `OFF`. While this causes us to create a static libgit2.a archive, it will not automatically cause CMake to only locate static archives when searching for dependencies. This does no harm in case of building our libgit2.a, as we do not want to include all required dependencies in the resulting archive anyway. Instead, we ask users of a static libgit2.a to link against the required set of static archives themselves, typically aided by the libgit2.pc file. Where it does cause harm, though, is when we build the libgit2_clar test suite. CMake has happily populated our LIBGIT2_LIBS variable with shared libraries, and so linking the final libgit2_clar test does not do the right thing. It will simply ignore those shared libraries, we end up with a test suite with undefined symbols. To fix the issue, we can instruct CMake to only locate libraries with a certain suffix. As static libraries are typically identifiable by their ".a" suffix on Unix-based systems, we can instruct CMake to only locate libraries with this suffix to restrict it from finding any shared libraries. This fixes building a static libgit2_clar test suite. Note that this ignores the problem on Windows. The problem here is that we cannot even distinguish static and dynamic libraries by only inspecting their suffix. So we just ignore the problem on Windows, for now.
cf9f3452	2017-09-06T07:38:32	cmake: bump minimum version to 2.8.11 Our current minimum CMake version is 2.8. This version does not yet allow us to use object libraries (introduced in 2.8.8) and target include directories (introduced in 2.8.12), which are both mechanisms we want to use to fix some specific problems. We previously were not able to bump our CMake version to a version supporting object libraries because Ubuntu Precise only had CMake version 2.8.7 in its repositories. But due to Precise being end of life now, we shouldn't need to honor it anymore. A current survey of some of the more conservative distributions brings up the following versions of CMake: - CentOS 5: 2.6.2 - CentOS 6: 2.8.12.2 - Debian 7: 2.8.11 - Fedora 23: 3.3.2 - OpenSUSE 13.2: 3.0.2 - Ubuntu Precise: 2.8.7 - Ubuntu Trusty: 2.8.12 The only two outliers here are CentOS 5 and Ubuntu Precise. CentOS is currently unsupported due to our minimum version being 2.8 and Ubuntu Precise is not maintained anymore. So the next smallest version supported by all major distributions is 2.8.11. While this does not yet support target include directories, it at least enables us to use object libraries. So this becomes our new minimum required version.

54214d61	2017-09-15T10:28:32	cmake: fix linker error with dbghelper library When the MSVC_CRTDBG option is set by the developer, we will link in the dbghelper library to enable memory lead detection in MSVC projects. We are doing so by adding it to the variable `CMAKE_C_STANDARD_LIBRARIES`, so that it is linked for every library and executable built by CMake. But this causes our builds to fail with a linker error: ``` LINK: fatal error LNK1104: cannot open file 'advapi32.lib;Dbghelp.lib' ``` The issue here is that we are treating the variable as if it were an array of libraries by setting it via the following command: ``` SET(CMAKE_C_STANDARD_LIBRARIES "${CMAKE_C_STANDARD_LIBRARIES}" "Dbghelp.lib") ``` The generated build commands will then simply stringify the variable, concatenating all the contained libraries with a ";". This causes the observed linking failure. To fix the issue, we should just treat the variabable as a simple string. So instead of adding multiple members, we just add the "Dbghelp.lib" library to the existing string, separated by a space character.
d630887b	2017-08-30T21:47:12	cmake: enable reproducible static linking By default, both ar(1) and ranlib(1) will insert additional information like timestamps into generated static archives and indices. As a consequence, generated static archives are not deterministic when created with default parameters. Both programs do support a deterministic mode, which will simply zero out undeterministic information with `ar D` and `ranlib -D`. Unfortunately, CMake does not provide an easy knob to add these command line parameters. Instead, we have to redefine the complete command definitons stored in the variables CMAKE_C_ARCHIVE_CREATE, CMAKE_C_ARCHIVE_APPEND and CMAKE_C_ARCHIVE_FINISH. Introduce a new build option `ENABLE_REPRODUCIBLE_BUILDS`. This option is available on Unix-like systems with the exception of macOS, which does not have support for the required flags. If the option is being enabled, we add those flags to the invocation of both `ar` and `ranlib` to enable deterministically building the static archive.
175ab8e7	2017-08-25T17:36:24	cmake: add switch to build with -Werror Add a simple switch to enable building with "-Werror=<warning>" instead of "-W<warning". Due to the encapsulated `ENABLE_WARNINGS` macro, this is as simple as adding a new variable "ENABLE_WERROR`, which can be passed on the command line via `-DENABLE_WERROR=ON`. The variable defaults to NO to not bother developers in their day to day work.
4a46a8c1	2017-08-25T17:32:54	cmake: encapsulate enabling/disabling compiler warnings There are multiple sites where we enable or disable compiler warning via "-W<warning>" or "-Wno-<warning>". As we want to extend this mechanism later on to conditionally switch these over to "-Werror=<warning>", we encapsulate the logic into its their own macros `ENABLE_WARNINGS` and `DISABLE_WARNINGS`. Note that we in fact have to use a macro here. Using a function would not modify the CFLAGS inside of the callers scope, but in the function's scope only.

32a2e500	2017-07-01T13:41:36	cmake: inline TARGET_OS_LIBRARIES function Previous to keeping track of libraries and linking directories via variables, we had two call sites of the `TARGET_OS_LIBRARIES` function to avoid duplicating knowledge on required operating system library dependencies. But as the libgit2_clar target now re-uses defined variables to link against these libraries, we can simply inline the function.
8e31cc25	2017-06-28T12:51:14	cmake: keep track of libraries and includes via lists Later on, we will move detection of required libraries, library directories as well as include directories into a separate CMakeLists.txt file inside of the source directory. Obviously, we want to avoid duplication here regarding these parameters. To prepare for the split, put the parameters into three variables LIBGIT2_LIBS, LIBGIT2_LIBDIRS and LIBGIT2_INCLUDES, tracking the required libraries, linking directory as well as include directories. These variables can later be exported into the parent scope from inside of the source build instructions, making them readily available for the other subdirectories.
dd332e2a	2017-06-23T20:42:41	cmake: use absolute path to deps When refering to files and directories inside of the top-level "deps/" directory, we're being inconsistent in using relative or absolute paths. To enable splitting out parts of the top-level CMakeLists.txt into an own file in the "src/" directory, consistently switch over to use absolute paths to avoid errors when converting.
8341d6cf	2017-07-04T10:57:28	cmake: move regcomp and futimens checks to "features.h" In our CMakeLists.txt, we have to check multiple functions in order to determine if we have to use our own or whether we can use the platform-provided one. For two of these functions, namely `regcomp_l()` and `futimens`, the defined macro is actually used inside of the header file "src/unix/posix.h". As such, these macros are not only required by the library, but also by our test suite, which is makes use of internal headers. To prepare for the CMakeLists.txt split, move these two defines inside of the "features.h" header.
a390a846	2017-07-01T13:06:00	cmake: move defines into "features.h" header In a future commit, we will split out the build instructions for our library directory and move them into a subdirectory. One of the benefits is fixing scoping issues, where e.g. defines do not leak to build targets where they do not belong to. But unfortunately, this does also pose the problem of how to propagate some defines which are required by both the library and the test suite. One way would be to create another variable keeping track of all added defines and declare it inside of the parent scope. While this is the most obvious and simplest way of going ahead, it is kind of unfortunate. The main reason to not use this is that these defines become implicit dependencies between the build targets. By simply observing a define inside of the CMakeLists.txt file, one cannot reason whether this define is only required by the current target or whether it is required by different targets, as well. Another approach would be to use an internal header file keeping track of all defines shared between targets. While configuring the library, we will set various variables and let CMake configure the file, adding or removing defines based on what has been configured. Like this, one can easily keep track of the current environment by simply inspecting the header file. Furthermore, these dependencies are becoming clear inside the CMakeLists.txt, as instead of simply adding a define, we now call e.g. `SET(GIT_THREADSAFE 1)`. Having this header file though requires us to make sure it is always included before any "#ifdef"-preprocessor checks are executed. As we have already refactored code to always include the "common.h" header file before any statement inside of a file, this becomes easy: just make sure "common.h" includes the new "features.h" header file first.
35087f0e	2017-06-28T15:42:54	cmake: create separate CMakeLists.txt for tests Our CMakeLists.txt is very unwieldy in its current size, spanning more than 700 lines of code. Furthermore, it has several issues regarding scoping, where for example some defines, includes, etc. from our test suite are also applied to our normal library code. To fix this, we can separate out build instructions for our tests and move them into their own CMakeLists.txt in the "tests" directory. This reduced complexity of the root CMakeLists.txt file and fixes the issues regarding leaking build context from tests into the library.
3267115f	2017-06-28T15:41:15	cmake: create own precompiled headers for tests As soon as we split up our CMakeBuild.txt build instructions, we will be unable to simply link against the git2 library's precompiled header from other targets. To avoid this future breakage, create a new precompiled header for our test suite. Next to being compatible with the split, this enables us to also include additional files like the clar headers, which may help speeding up compilation of the test suite.
caab8270	2017-06-23T19:07:01	cmake: create object library target Currently, we're compiling our library code twice, once as part of the libgit2 library and once for the libgit2_clar executable. Since CMake 2.8.8, there exists a new library type OBJECT, which represents an intermediate target which can then subsequently be used when linking several targets against the same set of objects. Use an OBJECT library to create an internal library for linking. This new target is only used on CMake v2.8.8 or newer. As CMake 3.0 changed the way how generator expressions are evaluated when accessing properties, we need to enable CMake policy 0051 to keep `IDE_SPLIT_SOURCES` functioning.
f33911e5	2017-06-23T18:32:48	cmake: remove unused variable "CLAR_RESOURCES" Once upon a time, the `CLAR_RESOURCES` variable was intended to set the `CLAR_RESOURCES` define. But actually, the define uses a wrong variable name by accident, hinting that its value cannot actually be used at all, as it is empty. Searching through the code base confirms the guess that the define is not used at all. Remove both the variable and definition.
096a49c0	2017-07-03T08:45:57	cmake: try to detect threads library While we already make use of the variable `${CMAKE_THREAD_LIBS_INIT}`, it is actually undefined due to us never including the "FindThreads" module in the CMakeLists.txt. It is rather curious as to why this has never triggered any error up to now, but it does in fact result in linking errors on some Unix platforms as soon as we split up our build instructions into multiple files. Fix the issue now to avoid future breakage by including the "FindThreads" module.
e5c9723d	2017-06-30T18:12:02	cmake: move library build instructions into subdirectory To fix leaking build instructions into different targets and to make the build instructions easier to handle, create a new CMakeLists.txt file containing build instructions for the libgit2 target. By now, the split is rather easy to achieve. Due to the preparatory steps, we can now simply move over all related build instructions, only needing to remove the "src/" prefix from some files.
72f27cb6	2017-06-30T17:02:00	cmake: fix up source and binary directory paths There are quite some uses of the variables "${CMAKE_CURRENT_SOURCE_DIR}" and "${CMAKE_CURRENT_BINARY_DIR}" where they are not appropriate. Convert these sites to instead use the variables "${CMAKE_SOURCE_DIR}" and "${CMAKE_BINARY_DIR}", which instead point to the project's root directory. This will ease splitting up the library build instructions into its own subdirectory.

845f661d	2017-06-21T20:02:48	cmake: Permit disabling external http-parser When attempting to build libgit2 as an isolated static lib, CMake gleefully attempts to use the system http-parser. This is typically seen on Linux systems which install header files with every package, such as Gentoo. Allow developers to forcibly disable using the system http-parser with the config switch USE_EXT_HTTP_PARSER. Defaults to ON to maintain previous behavior.

a64532e1	2017-06-13T11:05:09	cmake: disable optimization on debug builds While our debug builds on MSVC platforms already tune the code optimizer to aid debugging code, all the other platforms still use the default optimization level. This makes it hard for developers on these platforms to actually debug code while maintaining his sanity due to optimizations like inlined code, elided variables etc. To help this common use case, we can simply follow the MSVC example and turn off code optimization with "-O0" for debug builds. While it would be preferable to instead use "-Og" supported by more modern compilers, we cannot guarantee that this level is available on all supported platforms.
61399953	2017-06-13T11:03:38	cmake: set "-D_DEBUG" on non-Windows platforms In our code base, we have some occasions where we use the "_DEBUG" preprocessor macro to enable additional code which should not be part of release builds. While we define this flag on MSVC platforms, it is guarded by the conditional `WIN32 AND NOT CYGWIN` on other platforms since 19be3f9e6 (Improve MSVC compiler, linker flags, 2013-02-13). While this condition can be fulfilled by the MSVC platform, it is never encountered due to being part of the `ELSE` part of `IF (MSVC)`. The intention of the conditional was most likely to avoid the preprocessor macro on Cygwin platforms, but to include it on everthing else. As such, the correct condition here would be `IF (NOT CYGWIN)` instead. But digging a bit further, the condition is only ever used in two places: 1. To skip the test in "core::structinit", which should also work on Cygwin. 2. In "src/win32/git2.rc", where it is used to set additional file flags. As this file is included in MSVC builds only, it cannot cause any harm to set "_DEBUG" on Cygwin here. As such, we can simply drop the conditional and always set "-D_DEBUG" on all platforms.
e94be4c0	2017-06-13T11:08:19	cmake: remove stale comment on precompiled headers In commit 9f75a9ce7 (Turning on runtime checks when building debug under MSVC., 2012-03-30), we introduced a comment "Precompiled headers", which actually refers to no related commands. Seeing that the comment never had anything to refer to, we can simply remove it here.
db1abffa	2017-06-07T14:59:38	sha1dc: do not use standard includes The updated SHA1DC library allows us to use custom includes instead of using standard includes. Due to requirements with cross-platform, we provide some custom system includes files like for example the "stdint.h" file on Win32. Because of this, we want to make sure to avoid breaking cross-platform compatibility when SHA1DC is enabled. To use the new mechanism, we can simply define `SHA1DC_NO_STANDARD_INCLUDES`. Furthermore, we can specify custom include files via two defines, which we now use to include our "common.h" header.

528b2f7d	2016-09-05T13:24:07	cmake: add curl library path The `PKG_CHECK_MODULES` function searches a pkg-config module and then proceeds to set various variables containing information on how to link to the library. In contrast to the `FIND_PACKAGE` function, the library path set by `PKG_CHECK_MODULES` will not necessarily contain linking instructions with a complete path to the library, though. So when a library is not installed in a standard location, the linker might later fail due to being unable to locate it. While we already honor this when configuring libssh2 by adding `LIBSSH2_LIBRARY_DIRS` to the link directories, we fail to do so for libcurl, preventing us to build libgit2 on e.g. FreeBSD. Fix the issue by adding the curl library directory to the linker search path.

When we manually add the -fPIC flag to the compiler flags, MSYS2 will loudly complain about PIC being the default and thus not required. Fix the annoyance by stripping -fPIC in MSYS2 enviroments like it is already done for MinGW.

2018-02-16T10:50:54

CMakeLists: increase strict aliasing level to 3 The strict aliasing rules disallow dereferencing the pointer to a variable of a certain type as another type, which is frequently used e.g. when casting structs to their base type. We currently have the warning level for strict aliasing rules set to `2`, which is described by gcc(1) as being "Aggressive, quick, not too precise." And in fact, we experience quite a lot of warnings when doing a release build due to that. GCC provides multiple levels, where higher levels are more accurate, but also slower due to the additional analysis required. Still, we want to have warning level 3 instead of 2 to avoid the current warnings we have in the Travis CI release builds. As this is the default warning level when no level is passed to `-Wstrict-aliasing`, we can just remove the level and use that default.

However, in the code for versions from 3 onward we call `FEATURE_SUMMARY` with multiple kinds of elements to print in the same line. This is only supported in CMake 3.1 and later, making the rather popular CMake 3.0.2 unable to build the library. Use a single kind of element per invocation. This means we need to provide a "description" text, which CMake provides for us if provide multiple kinds of elements.

This is done in 49551254 (2017-09-22; cmake: use static dependencies when building static libgit2) but that commit included the rule too early, making it affect the search for iconv, meaning we did not find it when we were building a static libgit2. Move the rule to just before building clar, after we've included the rules for building the library itself. This lets us find and link to the dynamic libiconv.

This completely replaces the previous auto-selection.

cmake: use project-relative binary and source directories Due to our split of CMake files into multiple modules, we had to replace some uses of the `${CMAKE_CURRENT_SOURCE_DIR}` and `${CMAKE_CURRENT_BINARY_DIR}` variables and replace them with `${CMAKE_SOURCE_DIR}` and `${CMAKE_BINARY_DIR}`. This enabled us to still be able to refer to top-level files when defining build instructions inside of a subdirectory. When replacing all variables, it was assumed that the absolute set of variables is always relative to the current project. But in fact, this is not the case, as these variables always point to the source and binary directory as given by the top-levl project. So the change actually broke the ability to include libgit2 directly as a subproject, as source files cannot be found anymore. Fix this by instead using project-specific source and binary directories with `${libgit2_SOURCE_DIR}` and `${libgit2_BINARY_DIR}`.

Merge pull request #4356 from pks-t/pks/static-clar cmake: use static dependencies when building static libgit2

49551254

2017-09-22T09:34:37

cmake: use static dependencies when building static libgit2 CMake allows us to build a static library by simply setting the variable `BUILD_SHARED_LIBS` to `OFF`. While this causes us to create a static libgit2.a archive, it will not automatically cause CMake to only locate static archives when searching for dependencies. This does no harm in case of building our libgit2.a, as we do not want to include all required dependencies in the resulting archive anyway. Instead, we ask users of a static libgit2.a to link against the required set of static archives themselves, typically aided by the libgit2.pc file. Where it does cause harm, though, is when we build the libgit2_clar test suite. CMake has happily populated our LIBGIT2_LIBS variable with shared libraries, and so linking the final libgit2_clar test does not do the right thing. It will simply ignore those shared libraries, we end up with a test suite with undefined symbols. To fix the issue, we can instruct CMake to only locate libraries with a certain suffix. As static libraries are typically identifiable by their ".a" suffix on Unix-based systems, we can instruct CMake to only locate libraries with this suffix to restrict it from finding any shared libraries. This fixes building a static libgit2_clar test suite. Note that this ignores the problem on Windows. The problem here is that we cannot even distinguish static and dynamic libraries by only inspecting their suffix. So we just ignore the problem on Windows, for now.

cmake: bump minimum version to 2.8.11 Our current minimum CMake version is 2.8. This version does not yet allow us to use object libraries (introduced in 2.8.8) and target include directories (introduced in 2.8.12), which are both mechanisms we want to use to fix some specific problems. We previously were not able to bump our CMake version to a version supporting object libraries because Ubuntu Precise only had CMake version 2.8.7 in its repositories. But due to Precise being end of life now, we shouldn't need to honor it anymore. A current survey of some of the more conservative distributions brings up the following versions of CMake: - CentOS 5: 2.6.2 - CentOS 6: 2.8.12.2 - Debian 7: 2.8.11 - Fedora 23: 3.3.2 - OpenSUSE 13.2: 3.0.2 - Ubuntu Precise: 2.8.7 - Ubuntu Trusty: 2.8.12 The only two outliers here are CentOS 5 and Ubuntu Precise. CentOS is currently unsupported due to our minimum version being 2.8 and Ubuntu Precise is not maintained anymore. So the next smallest version supported by all major distributions is 2.8.11. While this does not yet support target include directories, it at least enables us to use object libraries. So this becomes our new minimum required version.

cmake: fix linker error with dbghelper library When the MSVC_CRTDBG option is set by the developer, we will link in the dbghelper library to enable memory lead detection in MSVC projects. We are doing so by adding it to the variable `CMAKE_C_STANDARD_LIBRARIES`, so that it is linked for every library and executable built by CMake. But this causes our builds to fail with a linker error: ``` LINK: fatal error LNK1104: cannot open file 'advapi32.lib;Dbghelp.lib' ``` The issue here is that we are treating the variable as if it were an array of libraries by setting it via the following command: ``` SET(CMAKE_C_STANDARD_LIBRARIES "${CMAKE_C_STANDARD_LIBRARIES}" "Dbghelp.lib") ``` The generated build commands will then simply stringify the variable, concatenating all the contained libraries with a ";". This causes the observed linking failure. To fix the issue, we should just treat the variabable as a simple string. So instead of adding multiple members, we just add the "Dbghelp.lib" library to the existing string, separated by a space character.

cmake: enable reproducible static linking By default, both ar(1) and ranlib(1) will insert additional information like timestamps into generated static archives and indices. As a consequence, generated static archives are not deterministic when created with default parameters. Both programs do support a deterministic mode, which will simply zero out undeterministic information with `ar D` and `ranlib -D`. Unfortunately, CMake does not provide an easy knob to add these command line parameters. Instead, we have to redefine the complete command definitons stored in the variables CMAKE_C_ARCHIVE_CREATE, CMAKE_C_ARCHIVE_APPEND and CMAKE_C_ARCHIVE_FINISH. Introduce a new build option `ENABLE_REPRODUCIBLE_BUILDS`. This option is available on Unix-like systems with the exception of macOS, which does not have support for the required flags. If the option is being enabled, we add those flags to the invocation of both `ar` and `ranlib` to enable deterministically building the static archive.

Note that we in fact have to use a macro here. Using a function would not modify the CFLAGS inside of the callers scope, but in the function's scope only.

Obviously, we want to avoid duplication here regarding these parameters. To prepare for the split, put the parameters into three variables LIBGIT2_LIBS, LIBGIT2_LIBDIRS and LIBGIT2_INCLUDES, tracking the required libraries, linking directory as well as include directories. These variables can later be exported into the parent scope from inside of the source build instructions, making them readily available for the other subdirectories.

cmake: move regcomp and futimens checks to "features.h" In our CMakeLists.txt, we have to check multiple functions in order to determine if we have to use our own or whether we can use the platform-provided one. For two of these functions, namely `regcomp_l()` and `futimens`, the defined macro is actually used inside of the header file "src/unix/posix.h". As such, these macros are not only required by the library, but also by our test suite, which is makes use of internal headers. To prepare for the CMakeLists.txt split, move these two defines inside of the "features.h" header.

2017-07-01T13:06:00

cmake: move defines into "features.h" header In a future commit, we will split out the build instructions for our library directory and move them into a subdirectory. One of the benefits is fixing scoping issues, where e.g. defines do not leak to build targets where they do not belong to. But unfortunately, this does also pose the problem of how to propagate some defines which are required by both the library and the test suite. One way would be to create another variable keeping track of all added defines and declare it inside of the parent scope. While this is the most obvious and simplest way of going ahead, it is kind of unfortunate. The main reason to not use this is that these defines become implicit dependencies between the build targets. By simply observing a define inside of the CMakeLists.txt file, one cannot reason whether this define is only required by the current target or whether it is required by different targets, as well. Another approach would be to use an internal header file keeping track of all defines shared between targets. While configuring the library, we will set various variables and let CMake configure the file, adding or removing defines based on what has been configured. Like this, one can easily keep track of the current environment by simply inspecting the header file. Furthermore, these dependencies are becoming clear inside the CMakeLists.txt, as instead of simply adding a define, we now call e.g. `SET(GIT_THREADSAFE 1)`. Having this header file though requires us to make sure it is always included before any "#ifdef"-preprocessor checks are executed. As we have already refactored code to always include the "common.h" header file before any statement inside of a file, this becomes easy: just make sure "common.h" includes the new "features.h" header file first.

cmake: create separate CMakeLists.txt for tests Our CMakeLists.txt is very unwieldy in its current size, spanning more than 700 lines of code. Furthermore, it has several issues regarding scoping, where for example some defines, includes, etc. from our test suite are also applied to our normal library code. To fix this, we can separate out build instructions for our tests and move them into their own CMakeLists.txt in the "tests" directory. This reduced complexity of the root CMakeLists.txt file and fixes the issues regarding leaking build context from tests into the library.

To avoid this future breakage, create a new precompiled header for our test suite. Next to being compatible with the split, this enables us to also include additional files like the clar headers, which may help speeding up compilation of the test suite.

cmake: create object library target Currently, we're compiling our library code twice, once as part of the libgit2 library and once for the libgit2_clar executable. Since CMake 2.8.8, there exists a new library type OBJECT, which represents an intermediate target which can then subsequently be used when linking several targets against the same set of objects. Use an OBJECT library to create an internal library for linking. This new target is only used on CMake v2.8.8 or newer. As CMake 3.0 changed the way how generator expressions are evaluated when accessing properties, we need to enable CMake policy 0051 to keep `IDE_SPLIT_SOURCES` functioning.

cmake: Permit disabling external http-parser When attempting to build libgit2 as an isolated static lib, CMake gleefully attempts to use the system http-parser. This is typically seen on Linux systems which install header files with every package, such as Gentoo. Allow developers to forcibly disable using the system http-parser with the config switch USE_EXT_HTTP_PARSER. Defaults to ON to maintain previous behavior.

cmake: disable optimization on debug builds While our debug builds on MSVC platforms already tune the code optimizer to aid debugging code, all the other platforms still use the default optimization level. This makes it hard for developers on these platforms to actually debug code while maintaining his sanity due to optimizations like inlined code, elided variables etc. To help this common use case, we can simply follow the MSVC example and turn off code optimization with "-O0" for debug builds. While it would be preferable to instead use "-Og" supported by more modern compilers, we cannot guarantee that this level is available on all supported platforms.

cmake: set "-D_DEBUG" on non-Windows platforms In our code base, we have some occasions where we use the "_DEBUG" preprocessor macro to enable additional code which should not be part of release builds. While we define this flag on MSVC platforms, it is guarded by the conditional `WIN32 AND NOT CYGWIN` on other platforms since 19be3f9e6 (Improve MSVC compiler, linker flags, 2013-02-13). While this condition can be fulfilled by the MSVC platform, it is never encountered due to being part of the `ELSE` part of `IF (MSVC)`. The intention of the conditional was most likely to avoid the preprocessor macro on Cygwin platforms, but to include it on everthing else. As such, the correct condition here would be `IF (NOT CYGWIN)` instead. But digging a bit further, the condition is only ever used in two places: 1. To skip the test in "core::structinit", which should also work on Cygwin. 2. In "src/win32/git2.rc", where it is used to set additional file flags. As this file is included in MSVC builds only, it cannot cause any harm to set "_DEBUG" on Cygwin here. As such, we can simply drop the conditional and always set "-D_DEBUG" on all platforms.

cmake: remove stale comment on precompiled headers In commit 9f75a9ce7 (Turning on runtime checks when building debug under MSVC., 2012-03-30), we introduced a comment "Precompiled headers", which actually refers to no related commands. Seeing that the comment never had anything to refer to, we can simply remove it here.

sha1dc: do not use standard includes The updated SHA1DC library allows us to use custom includes instead of using standard includes. Due to requirements with cross-platform, we provide some custom system includes files like for example the "stdint.h" file on Win32. Because of this, we want to make sure to avoid breaking cross-platform compatibility when SHA1DC is enabled. To use the new mechanism, we can simply define `SHA1DC_NO_STANDARD_INCLUDES`. Furthermore, we can specify custom include files via two defines, which we now use to include our "common.h" header.

cmake: only enable supported compiler warning flags We currently unconditionally enable the "-Wall" and "-Wextra" flags. Some platforms rely on compilers which do not support these flags, though. One of these platforms is Haiku, which does not support "-Wextra" due to being stuck on GCC version 2. Fix builds on such platforms by adding these flags only if supported by the compiler.

cmake: add curl library path The `PKG_CHECK_MODULES` function searches a pkg-config module and then proceeds to set various variables containing information on how to link to the library. In contrast to the `FIND_PACKAGE` function, the library path set by `PKG_CHECK_MODULES` will not necessarily contain linking instructions with a complete path to the library, though. So when a library is not installed in a standard location, the linker might later fail due to being unable to locate it. While we already honor this when configuring libssh2 by adding `LIBSSH2_LIBRARY_DIRS` to the link directories, we fail to do so for libcurl, preventing us to build libgit2 on e.g. FreeBSD. Fix the issue by adding the curl library directory to the linker search path.

cmake: do not use -fPIC for MSYS2 The MSYS2 build system automatically compiles all code with position-independent code. When we manually add the -fPIC flag to the compiler flags, MSYS2 will loudly complain about PIC being the default and thus not required. Fix the annoyance by stripping -fPIC in MSYS2 enviroments like it is already done for MinGW.

nsec: support NDK's crazy nanoseconds Android NDK does not have a `struct timespec` in its `struct stat` for nanosecond support, instead it has a single nanosecond member inside the struct stat itself. We will use that and use a macro to expand to the `st_mtim` / `st_mtimespec` definition on other systems (much like the existing `st_mtime` backcompat definition).
