* resolve problem: http server can't send file large than 2GB.
add unit test for http server send large file.
add /bigobj compile option to msvc x64.
* disable unit test "ServerLargeContentTest" due to out-of-memory on GitHub Actions.
- Enable THREADS_PREFER_PTHREAD_FLAG to use -pthread where supported
- Remove low-level compile features (closes#1272)
- Remove unneeded DESTINATION options where possible
Thanks to abf3a67dd070e138c0f1a20b913abf003193cb79 the use of python3
isn't required anymore to configure the build, so I moved the
find_program('python3') inside the "if compile" block.
This makes it possible to configure cpp-httplib on systems where python
isn't available with tools like muon: https://sr.ht/~lattis/muon/
* Add large data transfer test
* Replace `SSL_read` and `SSL_write` with `ex` functions
* Reflect review comment
* Fix return value of `SSLSocketStream::read/write`
* Fix return value in the case of `SSL_ERROR_ZERO_RETURN`
* Disable `LargeDataTransfer` test due to OoM in CI
Meson only runs required targets. The key_encrypted_pem and
cert_encrypted_pem targets added in 020b0db090dc8e197cbedbdc4db7e3120eda5333
and 8191fd8e6c5a27e034a34084afe61f17a9420cfa weren't added to the list
of targets required by the test target, so the generation of the
encrypted certs was skipped, resulting in the failure of
BindServerTest.BindAndListenSeparatelySSLEncryptedKey.
* meson: fix regression that broke extracting version
In commit 33f67386fec8040a36a26b2038b39dd8dcf2814d the code that
heuristically parsed the version broke due to the version being moved
around into a more easily accessible define.
While we are at it, pass the exact path of httplib.h to un-break usage
as a meson subproject. This was broken in commit
8ecdb1197967dea050fd38a8e9b5020e02320b31 which checked the return code
of trying to get the version; it was always broken, but formerly failed
in silence and resulted in no version number.
* meson: use the compiler builtins to extract the version from the header
As a convenient string define, it is now possible to ask the
preprocessor what the version of cpp-httplib is. This can be used from
meson too, in order to avoid encoding C++ file structure into python
regexes.
