Patrick Steinhardt 0298e0a6 2019-10-17T12:24:25 Merge pull request #5238 from tiennou/feature/macos-gss macOS GSS Support
Etienne Samson a088a1ff 2019-10-13T14:06:47 cmake: correct the link stanza for CoreFoundation 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`.
Etienne Samson dbc17a7e 2019-09-21T08:46:08 negotiate: use GSS.framework on macOS
Edward Thomson 63307cba 2019-09-28T17:32:18 Merge pull request #5226 from pks-t/pks/regexp-api regexp: implement a new regular expression API
Patrick Steinhardt f585b129 2019-09-12T14:29:28 posix: remove superseded POSIX regex wrappers The old POSIX regex wrappers have been superseded by our own regexp API that provides a higher-level abstraction. Remove the POSIX wrappers in favor of the new one.
Etienne Samson d80d9d56 2019-08-17T12:17:21 cmake: streamline *.pc file handling via a module
Patrick Steinhardt 212b6f65 2019-08-02T14:00:21 cmake: fix various misuses of MESSAGE() The MESSAGE() function expects as first argument the message type, e.g. STATUS or FATAL_ERROR. In some places, we were misusing this to either not provide any type, which would then erroneously print the message to standard error, or to use FATAL instead of FATAL_ERROR. Fix all of these instances. Also, remove some MESSAGE invocations that are obvious leftovers from debugging the build system.
Patrick Steinhardt e77fdf87 2019-08-02T13:49:36 cmake: properly abort if no mbedTLS cert location is found When using mbedTLS as backend, then the user may specify the location of where system certificates are installed. If no such location is provided by the user, CMake will try to autodetect the location by using the openssl executable, if installed. If no location could be detected, then the mbedTLS is essentially worthless as it is completely unable to verify any certificates. To avoid use of such misconfigured mbedTLS configurations, let's error out if we were unable to find out the location.
Etienne Samson 1ed10009 2019-09-06T10:32:06 cmake: remove extraneous logging
Patrick Steinhardt b7c247b3 2019-07-18T13:37:02 cmake: include SHA1 headers into our source files When selecting the SHA1 backend, we only include the respective C implementation of the selected backend. But since commit bd48bf3fb (hash: introduce source files to break include circles, 2019-06-14), we have introduced separate headers and compilation units for all hashes. So by not including the headers, we may not honor them to compute whether a file needs to be recompiled and they also will not be displayed in IDEs. Add the header files to fix this problem.
Patrick Steinhardt df54c7fb 2019-06-27T07:34:43 cmake: report whether we are using sub-second stat information Depending on the platform and on build options, we may or may not build libgit2 with support for nanoseconds when using `stat` calls. It's currently unclear though whether sub-second stat information is used at all. Add feature info for this to tell at configure time whether it's being used or not.
Patrick Steinhardt e9102def 2019-06-27T11:38:04 Merge pull request #4438 from pks-t/pks/hash-algorithm Multiple hash algorithms
Patrick Steinhardt fda20622 2019-06-14T14:22:19 hash: move SHA1 implementations into 'sha1/' folder As we will include additional hash algorithms in the future due to upstream git discussing a move away from SHA1, we should accomodate for that and prepare for the move. As a first step, move all SHA1 implementations into a common subdirectory. Also, create a SHA1-specific header file that lives inside the hash folder. This header will contain the SHA1-specific header includes, function declarations and the SHA1 context structure.
Edward Thomson cc9e47c9 2019-06-15T18:51:40 win32: support upgrading warnings to errors (/WX) For MSVC, support warnings as errors by providing the /WX compiler flags. (/WX is the moral equivalent of -Werror.) Disable warnings as errors ass part of xdiff, since it contains warnings. But as a component of git itself, we want to avoid skew and keep our implementation as similar as possible to theirs. We'll work with upstream to fix these issues, but in the meantime, simply let those continue to warn.
Patrick Steinhardt bd48bf3f 2019-06-14T14:21:32 hash: introduce source files to break include circles The hash source files have circular include dependencies right now, which shows by our broken generic hash implementation. The "hash.h" header declares two functions and the `git_hash_ctx` typedef before actually including the hash backend header and can only declare the remaining hash functions after the include due to possibly static function declarations inside of the implementation includes. Let's break this cycle and help maintainability by creating a real implementation file for each of the hash implementations. Instead of relying on the exact include order, we now especially avoid the use of `GIT_INLINE` for function declarations.
Etienne Samson 94fc83b6 2019-06-13T16:48:35 cmake: Modulize our TLS & hash detection The interactions between `USE_HTTPS` and `SHA1_BACKEND` have been streamlined. Previously we would have accepted not quite working configurations (like, `-DUSE_HTTPS=OFF -DSHA1_BACKEND=OpenSSL`) and, as the OpenSSL detection only ran with `USE_HTTPS`, the link would fail. The detection was moved to a new `USE_SHA1`, modeled after `USE_HTTPS`, which takes the values "CollisionDetection/Backend/Generic", to better match how the "hashing backend" is selected, the default (ON) being "CollisionDetection". Note that, as `SHA1_BACKEND` is still used internally, you might need to check what customization you're using it for.
Edward Thomson ce6d624a 2019-05-19T10:30:04 regex: optionally use PCRE2 Use PCRE2 and its POSIX compatibility layer if requested by the user. Although PCRE2 is adequate for our needs, the PCRE2 POSIX layer as installed on Debian and Ubuntu systems is broken, so we do not opt-in to it by default to avoid breaking users on those platforms.
Edward Thomson 69ecdad5 2019-05-19T10:09:55 regex: use system PCRE if available Attempt to locate a system-installed version of PCRE and use its POSIX compatibility layer, if possible.
cheese1 67562b23 2019-04-07T16:45:45 fix typo
lhchavez 6af6170b 2019-01-05T20:50:42 Make ENABLE_WERROR actually work This change explicitly adds -Werror to the CFLAGS. Due to the way that the ADD_C_FLAG_IF_SUPPORTED() macro was mangling the flag name to convert it into a define name, any warning that had a dash in its name was not being correctly enabled. Additionally, any flag that is enabled implicitly by the compiler (like -Wunused-result and -Wdeprecated-declarations) would not cause an error unless they were explicitly enabled with the ENABLE_WARNINGS() macro.
Etienne Samson 1a9cc182 2018-08-17T15:56:30 util: make the qsort_r check work on macOS This performs a compile-check by using CMake support, to differentiate the GNU version from the BSD version of qsort_r. Module taken from 4f252abea5f1d17c60f6ff115c9c44cc0b6f1df6, which I've checked against CMake 2.8.11.
Patrick Steinhardt 2e2d8c64 2018-08-24T09:53:39 cmake: detect and use libc-provided iconv While most systems provide a separate iconv library against which applications can link, musl based systems do not provide such a library. Instead, iconv functions are directly included in the C library. As our current CMake module to locate the iconv library only checks whether a library exists somewhere in the typical library directories, we will never build libgit2 with libiconv support on such systems. Extend the iconv module to also search whether libc provides iconv functions, which we do by checking whether the `iconv_open` function exists inside of libc. If this is the case, we will default to use the libc provided one instead of trying to use a separate libiconv. While this changes which iconv we use on systems where both libc and an external libiconv exist, to the best of my knowledge common systems only provide either one or the other. Note that libiconv support in musl is held kind of basic. To quote musl libc's page on functional differences from glibc [1]: The iconv implementation musl is very small and oriented towards being unobtrusive to static link. Its character set/encoding coverage is very strong for its size, but not comprehensive like glibc’s. As we assume iconv to be a lot more capable than what musl provides, some of our tests will fail if using iconv on musl-based platforms.

Patrick Steinhardt 186a7ba5 2018-07-19T15:13:40 cmake: error out if required C flags are not supported We do want to notify users compiling our source code early on if they try to use C flags which aren't supported. Add a new macro `AddCFlag`, which results in a fatal error in case the flag is not supported, and use it for our fuzzing flags.
Patrick Steinhardt 0f62e4c7 2018-04-27T10:38:49 cmake: resolve libraries found by pkg-config Libraries found by CMake modules are usually handled with their full path. This makes linking against those libraries a lot more robust when it comes to libraries in non-standard locations, as otherwise we might mix up libraries from different locations when link directories are given. One excemption are libraries found by PKG_CHECK_MODULES. Instead of returning libraries with their complete path, it will return the variable names as well as a set of link directories. In case where multiple sets of the same library are installed in different locations, this can lead the compiler to link against the wrong libraries in the end, when link directories of other dependencies are added. To fix this shortcoming, we need to manually resolve library paths returned by CMake against their respective library directories. This is an easy task to do with `FIND_LIBRARY`.

Etienne Samson 99d6ebb3 2017-09-06T22:01:50 cmake: make our macOS helpers more CMake-y
Etienne Samson 152f3766 2017-09-06T21:53:58 cmake: fix indentation before enhancing
Jiří Techet b7df2e8b 2015-05-01T22:48:33 Don't search iconv in /opt/local Since OpenSSL isn't used any more on OS X, there is no dependency on any MacPorts library under /opt/local and there is no danger of conflicts between MacPorts and system iconv. For this reason the system iconv can always be used now.
Carlos Martín Nieto 6bb54cbf 2014-11-02T13:23:32 Add a SecureTransport TLS channel As an alternative to OpenSSL when we're on OS X. This one can actually take advantage of stacking the streams.
Carlos Martín Nieto 4f91bfa3 2014-12-05T10:32:59 Find libssh2 via pkg-config We don't really need our own module to find libssh2. Using pkg-config lets the standard tool do the work for us and let us fit more naturally in the workflow as we respect the pkg-config search paths.
Edward Thomson 315cb38e 2014-07-31T18:43:20 Add GSSAPI support for SPNEGO/Kerberos auth over HTTP
Jacques Germishuys 5c8d5eac 2014-04-19T23:07:50 Introduce AddCFlagIfSupported CMake macro
Sascha Cunz 4bc94eb5 2014-01-30T03:01:46 We never search for libiconv via pkg-config So we actually also never know that we can set a dependency on it in pkg-config. Instead always give it the -L and -l options.
Sascha Cunz 6e0ff093 2014-01-30T02:30:55 Find and use a MacPorts version of libiconv. Fixes #2017. - Add correct -I, -L and -l flags - Search for libiconv in /opt/local/[include|lib] before in the system path. See #2017 for details. - Give splitted -L and -l arguments to pkg-config
Sascha Cunz 39949f06 2014-01-30T02:28:53 Cleanup FindIconv.cmake Doesn't change anything. Just removes stuff that was probably missed to remove when this was imported.
Russell Belfer 726b75d1 2013-12-02T11:32:37 Improve iconv finding for cmake * add FindIconv helper for CMake iconv detection * only default using iconv to ON for MacOS * update pkg-config generation to include iconv dependency better
