* Fix for compilation with MSVC permissive- (microsoft#809)

Related Visual Studio issue:
https://developercommunity.visualstudio.com/content/problem/238445/template-class-cant-access-protected-member-when-c.html

Problem is with code compiling with /permissive-, so the template functions are affected by this issue.

* Fix test issues under /permissive-

* Add root CMakeLists.txt

* Do not fail on unrecognized content encoding (such as chunked) when compression is enabled.

* Delete open() from _http_client_communicator (microsoft#819)

* Delete open() from _http_client_communicator and move its functionality into WinHTTP, as that is the only backend using that thing.

* Some CR comments from Robert.

* Fix boost1.63 build failure Fixes: microsoft#813 (microsoft#815)

* Fix gcc8 error/warning -Werror=format-truncation= (microsoft#787)

utilities::datetime::to_string(): datetime_str and buf were oversized
for fitting into output without possible trunctation

* [gcc-8][clang  -6] disable more -Werror warnings (microsoft#779)

gcc-8: -Wno-format-truncation

clang-6: -Wdelete-non-virtual-dtor
clang-6: -Wunused-lambda-capture

removed duplicated: -Wno-reorder

This fixes microsoft#778

* Fix some issues with gcc-5

* Remove empty objects when using CMake on Windows

* Don't enable certificate revocation check if client config has validate certificates set to false

* Add tests for set_validate_certificates(false).

* Unbreak ASIO build on Windows. (microsoft#821)

* Add branchless is_alnum borrowed from MSVC  's std::regex' _Is_word; should be about 5x faster. (microsoft#823)

The _Is_word change resulted in the following results in microbenchmarks; the previous is_alnum looks like branching_ranges.

* Unify handling of tolower operations to avoid locale sensitivity. (microsoft#822)

* Push version to 2.10.3

* Update changelog

* Deduplicate some code in HTTP headers. (microsoft#825)

* microsoft#436 Building iOS doesn’t seem to work (microsoft#776)

This moves iOS.cmake into the file so there is on need to add it. Also allows for boost to be static libs versus framework

* Improve error handling in on_accept (microsoft#750)

* Improve error handling in on_accept

* Move lock to the top of the function

* Lock shared data at the right locations.

* [http_listener] improve refcount and lifetime management by using RAII.

* Fix handling of timed out connections kept alive in connection pool under Unix (microsoft#762)

* Add asio_connection::was_closed_by_server() to reduce duplication

Reduce code duplication between ssl_proxy_tunnel::handle_status_line()
and the method with the same name in asio_context itself by moving the
common handling of connections closed by server into a new function.

No real changes, this is a pure refactoring.

* Fix checking for server-side closure of HTTPS connections

When an SSL connection times out due to being closed by server, a
different error code is returned, so we need to check for it too in
was_closed_by_server().

Without this, losing connection was not detected at all when using
HTTPS, resulting in "Failed to read HTTP status line" errors whenever
the same http_client was reused after more than the server keep alive
timeout of inactivity.

See microsoft#592.

* Fix bug with using re-opened connections with ASIO

Creating a new request when the existing connection being used was
closed by the server didn't work correctly because the associated input
stream was already exhausted, as its contents had been already "sent" to
the server using the now discarded connection, so starting a new request
using the same body stream never worked.

Fix this by explicitly rewinding the stream to the beginning before
using it again.

Note that even with this fix using a custom body stream which is not
positioned at the beginning initially (or which doesn't support
rewinding) still wouldn't work, but at least it fixes the most common
use case.

See microsoft#592.

* Reduce duplicate code between ssl_proxy and asio_context in handle_read_status_line.
Avoid increasing public surface with rewind function.

* Update CMakeLists.txt to install the cmake bindings in the right location (microsoft#737)

* Update CMakeLists.txt to install the cmake bindings in the right location

/usr/lib/cpprestsdk is not the correct FHS standard cmake location.
It should be placed in /usr/lib/<triplet>/cmake/cpprestsdk instead.

Same goes for libraries, support multiarch location if we use UNIX

* Revert changes to CPPREST_EXPORT_DIR. Use GNUInstallDirs on all platforms.

* Various micro perf fixes and cleanup found while implementing CN overrides so far (microsoft#818)

* Microperf: Use lock_guard instead of unique_lock.

* Bill hates lock_guard more.

* Ref them connections.

* Demacroize.

* Commonize port and merge some CRLFs into adjacent string literals.

* Add missing template keyword.

* Avoid stringstream in constructing the proxy_str.

* Remove unused forward declarations of some HTTP things.

* Use NOMINMAX instead of undef min and max everywhere.

* Bunch of inheritance hygiene.

* What do you mean you want examples to compile?

* More CR comments from Robert.

* Add static.

* Use existing to_string_t.

* fix template whitespace syntax (microsoft#715)

Some files don't have a space inbetween the '<' and '::' charachters, which
will cause build failures on older toolchains. Adding a space inbetween these
two characters fixes the issue.

See http://autobuild.buildroot.net/results/797a9b5fdf6ab0f16f2249324b48292dfab61d9f/build-end.log
for more information.

* Fix a build problem on Clang. (microsoft#732)

AND_CAPTURE_MEMBER_FUNCTION_POINTERS workaround had a check for GCC,
but did not exclude Clang.  Clang has a fake GCC version of 4.2, thus
caused problems.

* set the default open() O_CREAT file permissions to 666 (microsoft#736)

* Factor shared threadpool setup/teardown behavior out of platform dependent policies.

* Add initialize_with_threads feature to control thread count.

* Use double checked locking instead of call_once on Android due to paranoia.

* Workaround Apple clang bugs in constexpr evaluation. (microsoft#829)

* Add .clang-format file from vcpkg to cpprestsdk.

* Set namespace indentation to none.

* Apply clang-format to the asio implementation.

* Attempt to repair VS2013 builds. (microsoft#833)

* Implement host override of CN checking in the WinHTTP backend (microsoft#824)

* Implement CN overrides via the Host: header in the WinHTTP backend.

* Repair lack of fallback CN verification on Windows.

* Set security settings even for non-HTTPS URIs in WinHTTP, in case we get upgraded to SSL/TLS later.

* Add test to make sure this doesn't explode.

* Repair CPPREST_EXCLUDE_WEBSOCKETS support.

* Move x509_cert_utilities.h out of public headers.

* Avoid saying constexpr for VS2013. (microsoft#834)

* Implement host override of CN checking in the ASIO backend (microsoft#832)

* Implement host override of CN checking in the ASIO backend

Add new function calc_cn_host which applies our host header override policy.
Add the CN hostname used to asio_connection. Change the protocol such that the SSL upgrade request needs to come with the target hostname to use.
Replace std::deque in connection pooling with a version that has constant amortized time per insertion. (std::deque is only constant amortized time for insertions in terms of element operations, not overall). Factor out the replacement policy from the overall pool machinery.
Change release() to take shared_ptr&& to make sure the caller has let go.
Enable verify_cert_chain_platform_specific on Windows; otherwise OpenSSL says that the root CAs are untrusted and all SSL tests fail on Windows.
  This accidentially repairs these test cases on Windows:
  **** outside_tests:outside_wikipedia_compressed_http_response FAILED ****
  **** outside_tests:multiple_https_requests FAILED ****
  **** outside_tests:outside_ssl_json FAILED ****

* Add missing std::move.

* Use hot connections instead of cold connections in connection pool.

* Put timer start code back.

* Reset the shared_ptr when it is being dropped.

* Fix end comment broken by merge hell.

* Mint version 2.10.4

* Fix incorrect version.h. Fixes microsoft#942

* Fix another clang build failure (Fixes: microsoft#747) (microsoft#844)

* Fix another clang build failure (Fixes: microsoft#747)

* PR microsoft#711 "Update the build process for Boost on Android", also by
  jwtowner
* PR microsoft#714 "Improved the build process for cpprestsdk on Android", also
  by jwtowner.

The changes which required patching upstream Boost-for-Android in those
PRs has been stripped.

The NDK version targeted has been updated to 17c because that's what's
avaialble in Azure Pipelines.

Various compile failures this uncovered in cpprestsdk on Android were
fixed.

* Improve utf8_to_utf16 speed for common path

Conversion from UTF 8 to UTF 16 will consist mostly of single byte code points (e.g. parsing json bodies). This allows running single byte conversion in a tight loop that is only interrupted if multi byte handling becomes necessary.

Measurements for a very long string showed ~30% speed improvement

*  Resolve double free when WinHttpSendRequest fails (microsoft#1022)

* Update vcpkg.

* Resolve double free when WinHttpSendRequest fails

A customer reported that win WinHttpSendRequest fails, WinHTTP still
delivers WINHTTP_CALLBACK_STATUS_HANDLE_CLOSING callbacks. When
_start_request_send encountered a failure, it deleted the context
weak_ptr, and then the WINHTTP_CALLBACK_STATUS_HANDLE_CLOSING
also tried to delete it, resulting in double frees.

This change binds the weak_ptr to the handle more directly and avoids paying attention to WinHttpSendRequest.

* Fix upgrade to SSL after a proxy connect (hostname is required)

* Add the obvious missing constructor from a std::error_code and 'what' string message; cf. websocket_exception

* Update vcpkg. (microsoft#1053)

* Update vcpkg.

* Work around Azure Pipelines bug caused by global VCPKG_ROOT environment variable.

* Syntax error!

* Returns int64 value in function of seeking to file end on x64 Windows. (microsoft#1057)

* Don't close the output stream when reporting errors reading the body. (microsoft#1068)

This matches the asio implementation to what the winhttp implementation was doing.

Also turned on a test that looked related; I'm not positive that this change fixed that test but it passes for me now.

* Enable testing from root directory (microsoft#1064)

* Add --vcpkg-root to repair UWP.

* Update Boost_for_android for Android R19 (microsoft#1041)

This was forced on us by a change made in Azure Pipelines.

This change also builds Android with an updated copy of CMake; the version included with Ubuntu didn't have the Boost_ARCHITECTURE knob we need to change for the new -a32 and -x32 library suffixes.

* Gate stdext::checked_array_iterator usage on _ITERATOR_DEBUG_LEVEL (microsoft#1072)

* Add the missing ssl::context callback in websocket_client_config (microsoft#1049)

* Add the missing ssl::context callback in websocket_client_config, borrowing heavily from http_client

* Add dependency on Boost and OpenSSL when websocketpp is used for Secure WebSocket, just like for http_client when CPPREST_HTTP_CLIENT_IMPL STREQUAL "asio"

* Move get_jvm_env back into the crossplat namespace (microsoft#1073)

* Move get_jvm_env back into the crossplat namespace as it is declared in a header and used elsewhere.

* Add more missing crossplat:: qualifications.

* Mint v2.10.11. (microsoft#1074)

* Rewrite date formatting and parsing (microsoft#1076)

This overhauls the RFC 1123 and ISO 8601 parsing with bits copied from the autorest C prototype, giving more consistent behavior across platforms, and removing unintended locale dependencies. (For example, before on POSIX on a German machine we might emit Die, 19 Mär 2019 09:59:57 which would be rejected by servers)

There is a subtle breaking change in that we previously accepted a time with no date, e.g. "12:12:12Z", and this change rejects that. However, such input is not a valid ISO 8601 input, and we were crazy about how we handled it before. Before, on Windows we would fill in the date with whatever the current date is, but on POSIX we would fill in January 1, 1970. Considering this was never consistent, and considering 99.999% of internet customers are going to be using RFC 3339 which requires all the components, I've dropped that special case.

Lots of tests also added.

* Don't initialize atomic_flag with 0. (microsoft#1093)

* Avoid tripping over 32 bit time_t mistakes. (microsoft#1094)

Resolves microsoft#1090

* Allow error handling for time out in http_client_asio handle_connect (microsoft#1097)

* Update request_timeout_microsecond timeout (microsoft#1101)

Occasionally, on heavy loaded servers, or slow machines, 500 micro seconds is a too strict timeout.
Bump to 900 micro seconds instead

* Paranoia for overflow of sprintf buffer in the year 10000 (microsoft#1106)

* Parse and emit years from 1900 to 9999, and remove environment variable dependence on Android (microsoft#1117)

Update date formatting and parsing to accept all years between 1900 and 9999.

This unblocks the Azure Storage SDK which uses 9999-12-31 as a sentinel value for "no expiration time" which was broken by the locale insensitive date formatting's dependence on _mkgmtime, with its 1970-3000 range. By morally reimplementing _mkgmtime, this change also lets us remove the Android workaround of changing the TZ environment variable.

Release\tests\functional\utils\datetime.cpp

Turn on tests for values that would need 64 bits represented as a time_t, even for 32 bit time_t platforms.
Add year 1900 and 9999 test cases, and remove year 3000  and 1969- negative tests.
Release\tests\functional\http*

Drive by fix for new VS2019 warnings about narrowing.
Release\src\utilities\asyncrt_utils.cpp

Remove dependence on _mkgmtime and gmtime_r/gmtime_s by implementing replacements loosely inspired by both the C runtime's date operations and .NET's handling of the Gregorian calendar's 400 year cycle.

* Remove needless cast.

* Update boost and openssl on iOS.

* Use right path to test binaries.

* Shut off iOS builds.

* Use EVP_MAX_MD_SIZE instead of HMAC_MAX_MD_CBLOCK (microsoft#1155)

* Remove the address_configured flag on tcp::resolver::query (microsoft#1145)

The default behavior for tcp::resolver::query uses the
address_configured flag, which only returns addresses if a non-loopback
address is available on the system. If this is called before a real network
interface is brought up, then resolution will fail and the server won't
be functional, even for requests on the loopback interface.

Explicitly set the flags to default so that the address_configured flag
is not specified. This allows the server to start up normally even when
the system has no active network interfaces.

* add ping and pong to message handler (microsoft#1143)

Add ping and pong to message handler, and optional pong timeout

* Fix reusing ASIO http_client connecting to HTTPS server via proxy (microsoft#539)

Calling request() twice on the same client configured to connect to a
server via HTTPS didn't work under Unix because we issues CONNECT for
every request, meaning that, for the second one, we sent CONNECT via an
already established connection to the end server itself which,
unsurprisingly, didn't work at all.

Fix this by only setting up SSL tunnelling for a new connection but not
for the already used one.

* Fix issue microsoft#1171: Order of object destruction (microsoft#1175)

- Connection object is now destroyed before client object
- Client is destroyed only when wspp_callback_client is destroyed to prevent race condition with the destructor

* Remove proxy settings detection behavior in "default proxy mode."

This commit partially reverts microsoft@eb108ad in order to work around a reliability problem with WinHttpGetProxyForUrl. That function hangs unless there is an available thread pool thread to complete the WPAD request. As a result, if a customer issued ~512 concurrent HTTP requests, or otherwise needed that many thread pool threads, there would not be a thread available for WinHTTP to complete the operation, and the program would deadlock.

Moreover this call to WinHttpGetDefaultProxyConfiguration is extremely expensive, taking ~20% of overall CPU for the entire program for some Azure Storage SDK customers.

The function WinHttpGetProxyForUrlEx is supposed to help with this problem by being asynchronous, but that function was added in Windows 8, so we can't use it unconditionally. And on Windows 8.1 we already are using WINHTTP_ACCESS_TYPE_AUTOMATIC_PROXY instead of trying to do proxy autodetect ourselves.
