Subject: [PATCH 01/80] Cleanup files uploaded on request deletion (#266)

* http_request: Remove uploaded files in destructor

If the user needs those files, she should copy/move theme in the request
handler.

References: #264
Signed-off-by: Alexander Dahl <ada@thorsis.com>

* test: integ: file_upload: Remove redundant file delete

Not needed anymore. http_request destructor does cleanup now.

* test: integ: file_upload: Check uploaded files are deleted

* test: integ: file_upload: Stop webserver earlier

The webserver runs in a different thread than the test, therefor
deleting the uploaded files and checking if they are deleted might lead
into a race condition, and thus into tests failing sometimes, but not
always.

Moving the webserver stop and destructor behind the curl action should
be safe, every information needed for the test is copied to or in the
resource handler.

 * **A parametrized path. (e.g. `"/path/to/resource/with/{arg1}/{arg2}/in/url"`)**. In this case, the webserver will match the argument with any value passed. In addition to this, the arguments will be passed to the resource as part of the arguments (readable from the `http_request::get_arg` method - see [here](#parsing-requests)). For example, if passing `"/path/to/resource/with/{arg1}/{arg2}/in/url"` will match any request on URL with any value in place of `{arg1}` and `{arg2}`. 
 * **A parametrized path with custom parameters.** This is the same of a normal parametrized path, but allows to specify a regular expression for the argument (e.g. `"/path/to/resource/with/{arg1|[0-9]+}/{arg2|[a-z]+}/in/url"`. In this case, the webserver will match the arguments with any value passed that satisfies the regex. In addition to this, as above, the arguments will be passed to the resource as part of the arguments (readable from the `http_request::get_arg` method - see [here](#parsing-requests)). For example, if passing `"/path/to/resource/with/{arg1|[0-9]+}/{arg2|[a-z]+}/in/url"` will match requests on URLs like `"/path/to/resource/with/10/AA/in/url"` but not like `""/path/to/resource/with/BB/10/in/url""`
 * Any of the above marked as `family`. Will match any request on URLs having path that is prefixed by the path passed. For example, if family is set to `true` and endpoint is set to `"/path"`, the webserver will route to the resource not only the requests against  `"/path"` but also everything in its nested path `"/path/on/the/previous/one"`.

 The `http_resource` class represents a logical collection of HTTP methods that will be associated to a URL when registered on the webserver. The class is **designed for extension** and it is where most of your code should ideally live. When the webserver matches a request against a resource (see: [resource registration](#registering-resources)), the method correspondent to the one in the request (GET, POST, etc..) (see below) is called on the resource.
 
 Given this, the `http_resource` class contains the following extensible methods (also called `handlers` or `render methods`):
-* _**const std::shared_ptr<http_response>** http_resource::render_GET(**const http_request&** req):_ Invoked on an HTTP GET request.
-* _**const std::shared_ptr<http_response>** http_resource::render_POST(**const http_request&** req):_ Invoked on an HTTP POST request.
-* _**const std::shared_ptr<http_response>** http_resource::render_PUT(**const http_request&** req):_ Invoked on an HTTP PUT request.
-* _**const std::shared_ptr<http_response>** http_resource::render_HEAD(**const http_request&** req):_ Invoked on an HTTP HEAD request.
-* _**const std::shared_ptr<http_response>** http_resource::render_DELETE(**const http_request&** req):_ Invoked on an HTTP DELETE request.
-* _**const std::shared_ptr<http_response>** http_resource::render_TRACE(**const http_request&** req):_ Invoked on an HTTP TRACE request.
-* _**const std::shared_ptr<http_response>** http_resource::render_OPTIONS(**const http_request&** req):_ Invoked on an HTTP OPTIONS request.
-* _**const std::shared_ptr<http_response>** http_resource::render_CONNECT(**const http_request&** req):_ Invoked on an HTTP CONNECT request.
-* _**const std::shared_ptr<http_response>** http_resource::render(**const http_request&** req):_ Invoked as a backup method if the matching method is not implemented. It can be used whenever you want all the invocations on a URL to activate the same behavior regardless of the HTTP method requested. The default implementation of the `render` method returns an empty response with a `404`.

Subject: [PATCH 06/80] Use string_view in API methods where applicable (#288)

* Issue #286: use string_view in API methods where applicable

This change reduces required copying of immutable data primarily in the
HTTP request API. Methods returning strings now return string_view to
avoid copying immutable data from the underlying MHD impl.
get_*s methods still return a std::map which must be allocated
and constructed, but does not copy underlying strings.

Fix a few instances of these method calls in the code base.

Introduce some type aliases for maps from string_view to string_view,
string to string to reduce code verbosity.
Overload the comparator operator()s as required.

Provide overloads for dump_*_map functions and a template impl to avoid
code duplication.

Bump C++ version to 17 required to use string_view. Remove CI
configurations using ancient compilers that don't support string_view
or C++17

* remove accidentally added line of code

* fix data scope issue

In the file upload test, it was saving the arg_view_map from the
request, which went out of scope, leaving dangling refs.

Fix by making a deep copy.

* undo change from arg_map to arg_view_map

Because build_request_args makes a temp copy of underlying data and
mutates it, it is not feasible currently to return a view over that data.

* fix readme after changing get_args signature

* cache transformed data to return views over data

Add a data_cache type to the http request type, and a unique_ptr
instance member. This allows caching of transformed and/or copied data
from MHD, while preserving const-ness of all accessor methods.

Change all applicable methods to string_view, fix a few call sites.

There are a small number of places where error_log is called where it is expected to apply printf style formatting to it's extra arguments. In most of them, the extra arguments are the most important.

Subject: [PATCH 12/80] fix #292 handle argument keys with multiple values
 (#302)

* fix #292 handle argument keys with multiple values

This change allows the server to handle argument keys with multiple values
e.g. url?arg=param&arg=what

Previous, the arg key would just be overwritten with the next value. This
change adds a http_arg_value type to house all the values for a given key.

Adjust existing get_arg(s) methods, and add some get_arg_flat type
methods that still just return the first value for a given key.

Add a test case for multiple valued keys.

Add a test case for a large file upload that triggers chunking behavior
of MHD. This causes the server to concatenate file chunks within the
first value of the given arg key, so the test ensures that this
behavior is not affected by the changes.

change adds a http_arg_value type to house all the values for a given key.

Adjust existing get_arg(s) methods, and add some get_arg_flat type
methods that still just return the first value for a given key.

Add a test case for multiple valued keys.

Add a test case for a large file upload that triggers chunking behavior
of MHD. This causes the server to concatenate file chunks within the
first value of the given arg key, so the test ensures that this
behavior is not affected by the changes.

 All functions are guaranteed to be completely reentrant and thread-safe (unless differently specified).
 Additionally, clients can specify resource limits on the overall number of connections, number of connections per IP address and memory used per connection to avoid resource exhaustion.

 more limited systems (#307)

* Modify some integration tests to allow them to pass on systems that don't have port 8080 open or where the test don't run on a 'normal' file system (e.g. a sandbox full of symlinks).

Subject: [PATCH 18/80] Expand tests of resource resolution (#309)

* Add some test of how registired resources interactwith eachother.

* Add a test case for https://github.com/etr/libhttpserver/issues/308

* Make more picky warning settings happy.

* Make lint happy.

* Correct a test cases for -DCASE_INSENSITIVE

Also add a comment that the non `-DCASE_INSENSITIVE` testcases is probably wrong.

* Make lint happy about the TODO

Really this should be assigned to an issue report, not a person, because nobody has agreed to fix it yet.

Subject: [PATCH 21/80] Consider family_url in ordering of http_endpoint.
 (#306)

* Make more tests port configurable.

* Add test of current state for how registuring family resources works.

* Consider family_url in ordering of http_endpoint. This will allow calling register_resource independently for a path as a family and non-family.

* Don't put family patterns in registered_resources_str.

* Update test to match.

* Remove some comments that got copy/pasted in error.

Subject: [PATCH 27/80] Make more robust tests. (#312)

* Add a test verifying that the test content files are in fact readable.

* Also check HTTP responce code.

* Delete dead variable.

* Add include.

* Allow playing games with where the test_content files are (and thus relax what directory the test can be run from).

* Allow playing games with where the test_content files are (and thus relax what directory the test can be run from).

* Allow playing games with where the .pem files are (and thus relax what directory the test can be run from).

* Allow flexability for TCP ports on all the rest of the tests.

* Make sure register_resource calls don't fail.

* Make lint happy.

* Deal with cross thread error propogation.

* Deal with some special cases for loggin in littletest.

Subject: [PATCH 32/80] Fix bug preventing GET params from being read on
 parametrized URLs. (#326)

This also introduces tests to verify the bug doesn't return.

The bug was due to the populate_args method checking whether the
cache was empty before executing. By doing so, it was ignoring that
in case of parametrized URLs, the webserver class was loading the
params as arguments.

Subject: [PATCH 35/80] Add TLS-PSK authentication support via callback
 mechanism (#348)

* Add TLS-PSK authentication support via callback mechanism

This adds support for TLS Pre-Shared Key (PSK) authentication, allowing
secure connections without certificates using a shared secret key.

Changes:
- Add psk_cred_handler() builder method to create_webserver
- Add psk_cred_handler_callback typedef for PSK credential lookup
- Implement psk_cred_handler_func() static callback using GnuTLS
- Add MHD_OPTION_GNUTLS_PSK_CRED_HANDLER option when PSK is configured
- Add AM_CONDITIONAL for HAVE_GNUTLS in configure.ac
- Remove deprecated AC_HEADER_STDC macro
- Add minimal_https_psk example demonstrating PSK usage
- Add conditional GnuTLS linking in test/Makefile.am
- Update README.md with PSK documentation and example

The callback receives a username and returns the hex-encoded PSK,
or an empty string for unknown users.

* Update GitHub Actions to v4 (cache and checkout)

* Fix linker error: link all examples against gnutls when available

The library now uses GnuTLS functions (gnutls_malloc, gnutls_free,
gnutls_hex2bin) for PSK support, so all examples need to link against
gnutls when HAVE_GNUTLS is defined, not just the PSK example.

* Update CI for Ubuntu 24.04 compatibility

- Update sanitizer builds (asan, lsan, tsan, ubsan) from clang-13 to clang-18
- Move clang-11, clang-12, clang-13 tests to ubuntu-22.04
- Add new clang-14 through clang-17 tests on ubuntu-latest
- Add gcc-11 through gcc-14 tests
- Remove obsolete ubuntu-20.04 jobs (gcc-7, gcc-8, clang-6 through clang-10)
- Update IWYU job to use clang-18 on ubuntu-latest
- Fix cpplint errors: add missing includes and fix namespace indentation

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* Fix valgrind CI job for Ubuntu 24.04

- Remove valgrind-dbg package (debug symbols now included in main package)
- Update valgrind job to use GCC 14 instead of GCC 10

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* Use GCC 13 for valgrind job to avoid -Woverloaded-virtual error

GCC 14 with -Werror catches a latent warning in littletest.hpp test
framework that older compilers don't flag. Use GCC 13 for now.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* Fix issues with valgrind running on g++-14

* FIx issue with overloads in tests

* Fix issue with gnutls

* Fix all cpplint issues

* Added codacy suppressions

* No need for codacy yaml. It is configured via UI

 * _.https_mem_trust(**const std::string&** filename):_ String representing the path to a file containing the CA certificate to be used by the HTTPS daemon to authenticate and trust clients certificates. The presence of this option activates the request of certificate to the client. The request to the client is marked optional, and it is the responsibility of the server to check the presence of the certificate if needed. Note that most browsers will only present a client certificate only if they have one matching the specified CA, not sending any certificate otherwise.
 * _.https_priorities(**const std::string&** priority_string):_ SSL/TLS protocol version and ciphers. Must be followed by a string specifying the SSL/TLS protocol versions and ciphers that are acceptable for the application. The string is passed unchanged to gnutls_priority_init. If this option is not specified, `"NORMAL"` is used.
+* _.psk_cred_handler(**psk_cred_handler_callback** handler):_ Sets a callback function for TLS-PSK (Pre-Shared Key) authentication. The callback receives a username and should return the corresponding hex-encoded PSK, or an empty string if the user is unknown. This option requires `use_ssl()`, `cred_type(http::http_utils::PSK)`, and an appropriate `https_priorities()` string that enables PSK cipher suites. PSK authentication allows TLS without certificates by using a shared secret key.

Subject: [PATCH 37/80] Fix webserver thread safety (#350)

* add test

* Use const when possible

* Protect webserver::registered_resources_*

* Protect webserver::bans and webserver::allowances

* Split bans_and_allowances_mutex in two distinct mutexes

* Simplify `policy_callback` condition

* Fix cpplint style issues

- Move opening brace to end of line in policy_callback
- Replace using-directive with using-declaration for chrono_literals
- Use static_cast instead of C-style cast
- Use rand_r instead of rand for thread safety

Subject: [PATCH 38/80] Fix POST args with empty values not being parsed (issue
 #268) (#351)

* Fix POST args with empty values not being parsed (issue #268)

Destroy post processor before invoking the callback to ensure pending
POST body keys with empty values are properly finalized. Without this,
POST data like "arg1=val1&arg2=" would fail to include arg2.

The fix moves MHD_destroy_post_processor call to finalize_answer()
before the resource callback is invoked, rather than waiting for
the modded_request destructor.

Added test cases verifying:
- arg1=val1&arg2= correctly parses both args
- arg1= correctly parses as empty string
- arg1=&arg2= correctly parses both as empty strings

This supersedes PR #269 with the requested code style changes.

* Fix Windows build: replace rand_r with portable rand()

rand_r is POSIX-specific and not available on Windows. Since this is
just a stress test where thread-safe randomness isn't critical, use
the portable rand() function instead.

Subject: [PATCH 39/80] Fix deferred_response content parameter not being used
 (issue #331) (#352)

The deferred_response constructor accepts a content parameter that was
documented to send initial content before callback data, but was never
actually used. This fix stores the content and sends it first before
calling the user's callback.

Changes:
- Store content in initial_content member instead of passing to base class
- Track content_offset for proper chunking of large content
- Send initial content bytes before invoking user's cycle_callback
- Add test for backward compatibility with empty content parameter

Subject: [PATCH 40/80] Fix segfault when passing nullptr to register_resource
 (issue #265) (#353)

Add validation to reject null http_resource pointers in
webserver::register_resource(), throwing std::invalid_argument
instead of allowing a segfault at runtime when the resource is accessed.

Subject: [PATCH 41/80] Fix regex URL exact match bug (issue #308) (#354)

URLs that exactly match a registered regex pattern string were incorrectly
dispatching to that resource instead of returning 404. For example,
registering `/foo/{v|[a-z]}/bar` and then requesting the literal URL
`/foo/{v|[a-z]}/bar` returned 200 instead of 404.

The root cause was that URLs with regex patterns were being added to
`registered_resources_str` (fast string lookup map). When a request
matched the literal pattern text, it bypassed regex validation.

Fix: Only add URLs without regex patterns to the fast string lookup map
by checking `idx.get_url_pars().empty()` before insertion.

Subject: [PATCH 43/80] Fix Windows/MSYS2/MinGW64 build failures (issue #280)
 (#355)

* Fix Windows/MSYS2/MinGW64 build failures (issue #280)

Add MSYS environment support to configure.ac so users building from the
MSYS shell get proper Windows configuration (winsock2.h, ws2_32 lib)
instead of falling through to the Unix case (arpa/inet.h).

Changes:
- configure.ac: Add *-msys* case with Windows config and warning about
  msys-2.0.dll dependency
- configure.ac: Add host triplet and Windows build status to summary
- appveyor.yml: Add MSYS environment to CI matrix alongside MinGW64
- README.md: Add Windows/MSYS2 build section with step-by-step
  instructions and explanation of shell differences

* Migrate Windows CI from AppVeyor to GitHub Actions

Integrate Windows/MSYS2 builds into the existing verify job matrix
instead of using a separate AppVeyor configuration. This consolidates
all CI into GitHub Actions.

- Add MINGW64 and MSYS matrix entries with msys2 shell
- Add MSYS2 setup and package installation steps
- Add Windows-specific libmicrohttpd build with --enable-poll=no
- Remove AppVeyor configuration and badge

* Fix missing shell parameter in matrix include entries

Include entries don't inherit matrix defaults, so each needs an
explicit shell value to work with the defaults.run.shell setting.

* Fix shell for steps that run before MSYS2 setup

The git checkout and failure-handling steps need explicit shell: bash
since they may run before MSYS2 is set up or if MSYS2 setup fails.

* Fix MSYS package: use libcurl-devel for test headers

The curl package doesn't include development headers needed for
compiling tests. Use libcurl-devel which provides curl/curl.h.

* Fix MSYS package: add libgnutls-devel for SSL tests

The SSL tests (ssl_base, ssl_with_protocol_priorities, ssl_with_trust)
were failing because GnuTLS wasn't installed in the MSYS environment.

+### Building on Windows (MSYS2)
+
+MSYS2 provides multiple shell environments with different purposes. Understanding which shell to use is important:
+
+| Shell | Host Triplet | Runtime Dependency | Use Case |
+|-------|--------------|-------------------|----------|
+| **MinGW64** | `x86_64-w64-mingw32` | Native Windows | **Recommended** for native Windows apps |
+| **MSYS** | `x86_64-pc-msys` | msys-2.0.dll | POSIX-style apps, build tools |
+
+**Recommended: Use the MinGW64 shell** for building libhttpserver to produce native Windows binaries without additional runtime dependencies.
+
+#### Step-by-step build instructions
+
+1. Install [MSYS2](https://www.msys2.org/)
+
+2. Open the **MINGW64** shell (not the MSYS shell) from the Start Menu
+
+3. Install dependencies:
+```bash
+pacman -S --needed mingw-w64-x86_64-{gcc,libtool,make,pkg-config,doxygen,gnutls,curl} autotools
+```
+
+4. Build and install [libmicrohttpd](https://www.gnu.org/software/libmicrohttpd/) (>= 0.9.64)
+
+5. Build libhttpserver:
+```bash
+./bootstrap
+mkdir build && cd build
+../configure --disable-fastopen
+make
+make check  # run tests
+```
+
+**Important:** The `--disable-fastopen` flag is required on Windows as TCP_FASTOPEN is not supported.
+
+#### If you use the MSYS shell
+
+Building from the MSYS shell also works but the resulting binaries will depend on `msys-2.0.dll`. The configure script will display a warning when building in this environment. If you see:
+
+```
+configure: WARNING: Building from MSYS environment. Binaries will depend on msys-2.0.dll.
+```
+
+Consider switching to the MinGW64 shell for native Windows binaries.

Subject: [PATCH 44/80] Add documentation about library files on Windows (issue
 #276)

Document that .dll.a is the correct import library format for GCC
toolchains (MSYS2/MinGW, Cygwin), and that .lib files are MSVC-specific.
Also add linking examples using pkg-config and manual flags.

Closes #276

+#### Library files on Windows
+
+When building with GCC-based toolchains (MSYS2/MinGW, Cygwin), the following library files are generated:
+
+| File | Purpose |
+|------|---------|
+| `libhttpserver.a` | Static library archive |
+| `libhttpserver.dll` | Shared library (DLL) |
+| `libhttpserver.dll.a` | Import library for linking against the DLL |
+| `libhttpserver.la` | Libtool archive (used by libtool during linking) |
+
+**Note about `.lib` files:** The `.dll.a` format is the import library format used by GCC toolchains. If you're looking for `.lib` files, those are the MSVC (Microsoft Visual C++) import library format and are only generated when building with the MSVC toolchain. The `.dll.a` file serves the same purpose as `.lib` but for GCC-based compilers.
+
+**Linking against libhttpserver:**
+
+Using pkg-config (recommended):
+```bash
+g++ myapp.cpp $(pkg-config --cflags --libs libhttpserver) -o myapp
+```
+
+Manual linking:
+```bash
+g++ myapp.cpp -I/mingw64/include -L/mingw64/lib -lhttpserver -lmicrohttpd -o myapp
+```

Subject: [PATCH 45/80] Add file cleanup callback for uploaded files (issues
 #264, #270) (#356)

Add a server-level callback that allows users to customize file cleanup
behavior for uploaded files. Previously, all uploaded files were
automatically deleted when the request completed, making it impossible
to keep or move files to permanent storage.

The new file_cleanup_callback option accepts a function with signature:
  bool(const std::string& key, const std::string& filename,
       const http::file_info& info)

Return true to delete the file (default behavior) or false to keep it.
If the callback throws an exception, the file is deleted as a safety
measure. When no callback is set, files are deleted (backward compatible).

Changes:
- Add file_cleanup_callback_ptr typedef and builder method
- Store callback in webserver and pass to http_request
- Modify http_request destructor to invoke callback per file
- Add 5 test cases covering callback behavior
- Add file_upload_with_callback example
- Update README with documentation and example

The resource will also have to be registered as family. (For more information on resource registration, read more [here](#registering-resources)). `off` by default.

Subject: [PATCH 46/80] Make digest auth support conditional (issue #232)
 (#357)

* Make digest auth support conditional (issue #232)

When libmicrohttpd is built with --disable-dauth, the digest auth
functions (MHD_digest_auth_get_username, MHD_digest_auth_check,
MHD_queue_auth_fail_response) are not available, causing linker errors.

This change detects digest auth availability at configure time and
conditionally compiles the digest auth code, following the existing
pattern used for GnuTLS support.

Changes:
- Add AC_CHECK_LIB detection for MHD_queue_auth_fail_response
- Add HAVE_DAUTH preprocessor flag when digest auth is available
- Wrap digest auth code in #ifdef HAVE_DAUTH guards
- Show digest auth status in configure summary

* Make digest_authentication example conditional (issue #232)

Build the digest_authentication example only when HAVE_DAUTH is defined,
consistent with the conditional digest auth support added in the library.

* Guard digest auth MHD options with HAVE_DAUTH (issue #232)

When libmicrohttpd is built with --disable-dauth, passing
MHD_OPTION_NONCE_NC_SIZE or MHD_OPTION_DIGEST_AUTH_RANDOM to
MHD_create_daemon() causes daemon creation to fail. This fixes
the ws_start_stop test failure in the no-dauth CI build.

Subject: [PATCH 47/80] Documentation improvements (issues #334, #324, #343)
 (#358)

* Documentation improvements (issues #334, #324, #343)

- Remove obsolete INSTALL file (issue #334): The generic autoconf INSTALL
  file incorrectly mentioned `make -f Makefile.cvs` instead of `./bootstrap`.
  README.md already contains accurate build instructions.

- Add args_processing.cpp example (issue #324): Demonstrates how to use
  get_args() and get_args_flat() methods to iterate over all request
  arguments, including handling parameters with multiple values.

- Add bind_address(string) overload (issue #343): Allows binding to a
  specific IP address using a string (e.g., "127.0.0.1") instead of
  requiring manual sockaddr construction. Supports both IPv4 and IPv6.
  IPv6 mode is automatically enabled when an IPv6 address is provided.

- Document bind_address() methods in README.md (issue #343): Added
  documentation for both the sockaddr* and string overloads.

* Fix macro redefinition warning in create_webserver.cpp

Remove explicit #define HTTPSERVER_COMPILATION as it is already
defined by the build system via command line flags.

* Fix memory leak: copy bind_address_storage to webserver

The webserver was only copying the raw bind_address pointer but not the
shared_ptr that owns the storage. This caused the memory to be freed
when the temporary create_webserver was destroyed, leaving webserver
with a dangling pointer and causing valgrind to report a leak.

* CI: Print valgrind memcheck log on success or failure

Move the memcheck log printing to a separate step that runs with
always() condition, so the log is printed regardless of whether
the valgrind check passes or fails. This helps debug valgrind
failures in CI.

-are permitted in any medium without royalty provided the copyright
-notice and this notice are preserved.  This file is offered as-is,
-without warranty of any kind.
-
-Basic Installation
-==================
-
-   Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package.  The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.  Some packages provide this
-`INSTALL' file but do not implement all of the features documented
-below.  The lack of an optional feature in a given package is not
-necessarily a bug.  More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-   The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-  	 `make -f Makefile.cvs` to create configure file.
-
-  2. `./configure' to configure the package for your system.
-
-     Running `configure' might take a while.  While running, it prints
-     some messages telling which features it is checking for.
-
-  3. Type `make' to compile the package.
-
-  4. Optionally, type `make check' to run any self-tests that come with
-     the package, generally using the just-built uninstalled binaries.
-
-  5. Type `make install' to install the programs and any data files and
-     documentation.  When installing into a prefix owned by root, it is
-     recommended that the package be configured and built as a regular
-     user, and only the `make install' phase executed with root
-     privileges.
-
-  6. Optionally, type `make installcheck' to repeat any self-tests, but
-     this time using the binaries in their final installed location.
-     This target does not install anything.  Running this target as a
-     regular user, particularly if the prior `make install' required
-     root privileges, verifies that the installation completed
-     correctly.
-
-  7. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-  8. Often, you can also type `make uninstall' to remove the installed
-     files again.  In practice, not all packages have tested that
-     uninstallation works correctly, even though it is required by the
-     GNU Coding Standards.
-
-  9. Some packages, particularly those that use Automake, provide `make
-     distcheck', which can by used by developers to test that all other
-     targets like `make install' and `make uninstall' work correctly.
-     This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.  This
-is known as a "VPATH" build.
-
-   With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
-   By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc.  You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.  In general, the
-default for these options is expressed in terms of `${prefix}', so that
-specifying just `--prefix' will affect all of the other directory
-specifications that were not explicitly provided.
-
-   The most portable way to affect installation locations is to pass the
-correct locations to `configure'; however, many packages provide one or
-both of the following shortcuts of passing variable assignments to the
-`make install' command line to change installation locations without
-having to reconfigure or recompile.
-
-   The first method involves providing an override variable for each
-affected directory.  For example, `make install
-prefix=/alternate/directory' will choose an alternate location for all
-directory configuration variables that were expressed in terms of
-`${prefix}'.  Any directories that were specified during `configure',
-but not in terms of `${prefix}', must each be overridden at install
-time for the entire installation to be relocated.  The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.
-However, some platforms have known limitations with the semantics of
-shared libraries that end up requiring recompilation when using this
-method, particularly noticeable in packages that use GNU Libtool.
-
-   The second method involves providing the `DESTDIR' variable.  For
-example, `make install DESTDIR=/alternate/directory' will prepend
-`/alternate/directory' before all installation names.  The approach of
-`DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters.  On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of `${prefix}'
-at `configure' time.
-
-Optional Features
-=================
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-   Some packages offer the ability to configure how verbose the
-execution of `make' will be.  For these packages, running `./configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with `make V=1'; while running `./configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with `make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
-a workaround.  If GNU CC is not installed, it is therefore recommended
-to try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
-   On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug.  Until the bug is fixed you can use this workaround:
-
-     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
-     Print a summary of the options unique to this package's
-     `configure', and exit.  The `short' variant lists options used
-     only in the top level, while the `recursive' variant lists options
-     also present in any nested packages.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to
-     disable caching.
-
-`--config-cache'
-`-C'
-     Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--prefix=DIR'
-     Use DIR as the installation prefix.  *note Installation Names::
-     for more details, including other options available for fine-tuning
-     the installation locations.
-
-`--no-create'
-`-n'
-     Run the configure checks, but stop before creating any output
-     files.
-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

 * _.connection_timeout(**int** timeout):_ Determines after how many seconds of inactivity a connection should be timed out automatically. The default timeout is `180 seconds`.
 * _.memory_limit(**int** memory_limit):_ Maximum memory size per connection (followed by a `size_t`). The default is 32 kB (32*1024 bytes). Values above 128k are unlikely to result in much benefit, as half of the memory will be typically used for IO, and TCP buffers are unlikely to support window sizes above 64k on most systems.
 * _.per_IP_connection_limit(**int** connection_limit):_ Limit on the number of (concurrent) connections made to the server from the same IP address. Can be used to prevent one IP from taking over all of the allowed connections. If the same IP tries to establish more than the specified number of connections, they will be immediately rejected. The default is `0`, which means no limit on the number of connections from the same IP address.
+* _.bind_address(**const struct sockaddr*** address):_ Bind the server to a specific network interface by passing a pre-constructed `sockaddr` structure. This gives full control over the address configuration but requires manual socket address setup.
+* _.bind_address(**const std::string&** ip):_ Bind the server to a specific network interface by IP address string (e.g., `"127.0.0.1"` for localhost only, or `"192.168.1.100"` for a specific interface). Supports both IPv4 and IPv6 addresses. When an IPv6 address is provided, IPv6 mode is automatically enabled. Example: `create_webserver(8080).bind_address("127.0.0.1")`.
 * _.bind_socket(**int** socket_fd):_ Listen socket to use. Pass a listen socket for the daemon to use (systemd-style). If this option is used, the daemon will not open its own listen socket(s). The argument passed must be of type "int" and refer to an existing socket that has been bound to a port and is listening.
 * _.max_thread_stack_size(**int** stack_size):_ Maximum stack size for threads created by the library. Not specifying this option or using a value of zero means using the system default (which is likely to differ based on your platform). Default is `0 (system default)`.
 * _.use_ipv6() and .no_ipv6():_ Enable or disable the IPv6 protocol support (by default, libhttpserver will just support IPv4). If you specify this and the local platform does not support it, starting up the server will throw an exception. `off` by default.

Subject: [PATCH 48/80] Add centralized authentication handler (issue #102)
 (#359)

Add auth_handler callback to webserver that runs before any resource's
render method. This allows defining authentication logic once for all
resources instead of duplicating it in every render method.

Features:
- auth_handler: callback that returns nullptr to allow request or
  http_response to reject
- auth_skip_paths: vector of paths to bypass auth (supports exact
  match and wildcard suffix like "/public/*")

Includes comprehensive tests and example in
examples/centralized_authentication.cpp

+### Using Centralized Authentication
+The examples above show authentication handled within each resource's `render_*` method. This approach requires duplicating authentication logic in every resource, which is error-prone and violates DRY (Don't Repeat Yourself) principles.
+
+libhttpserver provides a centralized authentication mechanism that runs a single authentication handler before any resource's render method is called. This allows you to:
+- Define authentication logic once for all resources
+- Automatically protect all endpoints by default
+- Specify paths that should bypass authentication (e.g., health checks, public APIs)
+
+```cpp
+    #include <httpserver.hpp>
+
+    using namespace httpserver;
+
+    // Resources no longer need authentication logic
+    class hello_resource : public http_resource {
+    public:
+        std::shared_ptr<http_response> render_GET(const http_request&) {
+            return std::make_shared<string_response>("Hello, authenticated user!", 200, "text/plain");
+        }
+    };
+
+    class health_resource : public http_resource {
+    public:
+        std::shared_ptr<http_response> render_GET(const http_request&) {
+            return std::make_shared<string_response>("OK", 200, "text/plain");
+        }
+    };
+
+    // Centralized authentication handler
+    // Return nullptr to allow the request, or an http_response to reject it
+    std::shared_ptr<http_response> my_auth_handler(const http_request& req) {
+        if (req.get_user() != "admin" || req.get_pass() != "secret") {
+            return std::make_shared<basic_auth_fail_response>("Unauthorized", "MyRealm");
+        }
+        return nullptr;  // Allow request to proceed to resource
+    }
+
+    int main() {
+        webserver ws = create_webserver(8080)
+            .auth_handler(my_auth_handler)
+            .auth_skip_paths({"/health", "/public/*"});
+
+        hello_resource hello;
+        health_resource health;
+
+        ws.register_resource("/api", &hello);
+        ws.register_resource("/health", &health);
+
+        ws.start(true);
+        return 0;
+    }
+```
+
+The `auth_handler` callback is called for every request before the resource's render method. It receives the `http_request` and can:
+- Return `nullptr` to allow the request to proceed normally
+- Return an `http_response` (e.g., `basic_auth_fail_response` or `digest_auth_fail_response`) to reject the request
+
+The `auth_skip_paths` method accepts a vector of paths that should bypass authentication:
+- Exact matches: `"/health"` matches only `/health`
+- Wildcard suffixes: `"/public/*"` matches `/public/`, `/public/info`, `/public/docs/api`, etc.
+
+To test the above example:
+
+    # Without auth - returns 401 Unauthorized
+    curl -v http://localhost:8080/api
+
+    # With valid auth - returns 200 OK
+    curl -u admin:secret http://localhost:8080/api
+
+    # Health endpoint (skip path) - works without auth
+    curl http://localhost:8080/health
+
+You can also check this example on [github](https://github.com/etr/libhttpserver/blob/master/examples/centralized_authentication.cpp).

Subject: [PATCH 49/80] Add HA1-based digest authentication support (#360)

* Add HA1-based digest authentication support

Adds check_digest_auth_ha1() method that accepts pre-computed HA1 hash
bytes instead of plaintext password. This allows secure storage of
password hashes rather than plaintext passwords.

Changes:
- Add digest_algorithm enum (MD5, SHA256) without AUTO since
  libmicrohttpd cannot auto-detect algorithm from raw hash bytes
- Add md5_digest_size and sha256_digest_size constants
- Add check_digest_auth_ha1() to http_request
- Add integration tests for HA1-based digest authentication

* Extend digest_auth_fail_response for algorithm specification

- Add algorithm parameter to digest_auth_fail_response constructor
  (defaults to MD5 for backward compatibility)
- Use MHD_queue_auth_fail_response2() to specify the algorithm in
  the WWW-Authenticate challenge header
- Add separate MD5 and SHA256 test resources for deterministic testing
- Add SHA256 digest auth tests alongside existing MD5 tests

This enables server-driven algorithm selection, where the server
requests a specific digest algorithm in the challenge and curl
responds using that algorithm.

Subject: [PATCH 50/80] Fix codecov upload condition in CI workflow (#361)

* Fix codecov upload condition in CI workflow

The upload condition used 'discard' which never matches any matrix
value, preventing coverage data from being uploaded. Changed to 'ubuntu'
to match the actual os-type matrix value.

* Replace deprecated Codecov bash uploader with official GitHub Action

The bash uploader now requires a token and is deprecated.
Using codecov/codecov-action@v5 which handles authentication
automatically for public repos via GitHub OIDC.

* Add gcovr step to generate coverage report before Codecov upload

The codecov-action@v5 does not auto-process gcov data like the old bash
uploader did. This adds a step to run gcovr to convert .gcda/.gcno files
to Cobertura XML format, which codecov can parse.

* Add CODECOV_TOKEN for protected branch uploads

Codecov requires authentication token for uploading coverage reports
to protected branches.

* Trigger CI to test Codecov upload with token

* Add --root option to gcovr for correct source path mapping

The coverage report was unusable because gcovr generated paths relative
to the build directory (e.g., ../src/webserver.cpp). Adding --root ..
ensures paths are relative to the repository root, allowing Codecov to
correctly match source files.

* Exclude test directory from coverage reports

* Ignore tests

From 3be9e7c21de9bc9911c688f7780a4c5eaf1d94d6 Mon Sep 17 00:00:00 2001
From: Sebastiano Merlino <sebastiano@hey.com>

Subject: [PATCH 51/80] Add tests for untested HTTP methods and
 request/response getters (#362)

* Add tests for untested HTTP methods and request/response getters

- Add HEAD, OPTIONS, TRACE method handlers to complete_test_resource
- Add integration tests for HEAD, OPTIONS, TRACE HTTP methods
- Add request_info_resource and test for get_requestor(), get_requestor_port(), get_version()
- Add content_limit_suite to test content_too_large() with content_size_limit
- Add unregister_then_404 test for webserver::unregister_resource()
- Create http_response unit test file with tests for response code, headers, footers, and cookies

These tests increase coverage for previously untested code paths in
webserver.cpp, http_request.cpp, and http_response.cpp.

* Add additional coverage tests for networking and TLS features

- Add IPv6 and dual-stack webserver tests
- Add HTTPS webserver and TLS session getter tests with graceful failure handling
- Add bind_address_ipv4 test with runtime URL building
- Add shoutcast response test for MHD_ICY_FLAG verification
- Add string_response constructor tests
- Remove CONNECT method test (incompatible with curl's tunneling semantics)

Coverage improved from ~90% to 91.8% lines, 93.3% functions.

* Add print-summary to gcovr for coverage debugging

Add --print-summary flag to gcovr command in CI to help diagnose
the discrepancy between local coverage (91.8%) and Codecov (64.53%).

* Filter gcovr to src/ directory only

The coverage report was including 15,781 lines from system headers and
dependencies instead of just the ~1,500 lines of libhttpserver source.
Use --filter to restrict coverage to src/ directory only.

* Add coverage tests for footers, PSK handlers, and ban/allow weights

- Add footer/trailer tests for http_request and http_response
- Add PSK handler configuration tests (setup, empty handler, no handler)
- Add ban/allow IP weight comparison tests for specific-then-wildcard case
- Add auth skip path tests for root path and wildcards
- Add IPv6 parsing edge case tests (too many parts, wildcards, nested)
- Add http_endpoint invalid regex pattern test
- Add custom error handler tests (not_found, method_not_allowed)
- Add request info caching tests

Branch coverage: 60.4% -> 64.2% (+65 branches)
Line coverage: 91.8% -> 94.9%

* Add Phase 2 branch coverage tests for http_request and http_endpoint

- Add null value query parameter test covering nullptr branches in
  build_request_args and build_request_querystring (lines 234, 248)
- Add digested user caching tests for cache hit and nullptr branches
  (lines 293-295, 300) in http_request.cpp
- Add caret prefix URL pattern tests covering line 85 in http_endpoint.cpp
- Add consecutive slashes URL test covering empty parts handling (line 83)

Branch coverage improvements:
- http_endpoint.cpp: 66.9% -> 68.7%
- http_request.cpp: 58.5% -> 59.7%

* Add Phase 3 branch coverage tests for render methods and error handling

- Add tests for all HTTP methods falling through to base render()
- Add custom internal error resource handler test
- Add get_arg_flat fallback test
- Add large multipart form field test (100KB)
- Add file upload with explicit content-type header test
- Add http_endpoint tests for regex validation and error paths
- Add tests for invalid URL parameter formats

* Fix cpplint issues in test files

- Replace static global strings with function-static pattern
- Change 'long' to 'int64_t' for http_code variables
- Add missing #include <utility> for std::move

* Added PSK tests

* Fix Windows test failure and add hex utility coverage

- Fix file_upload tests to use subdirectory instead of /tmp for
  cross-platform compatibility
- Extract hex validation functions (is_valid_hex, hex_char_to_val)
  from webserver.cpp to string_utilities for testability
- Add unit tests for hex utility functions to improve coverage

* Fix Windows mkdir compatibility issue

On Windows/MinGW, mkdir() only takes one argument (path), while
POSIX mkdir() takes two (path and mode). Add a MKDIR macro that
uses the appropriate signature for each platform.

Subject: [PATCH 52/80] Add ARM cross-compilation to GitHub Actions CI

Add ARM32 (ARMv7 hard-float) and ARM64 (AArch64) cross-compilation
testing to the CI workflow. This validates that libhttpserver can be
built for ARM targets using cross-compilation toolchains.

Changes:
- Add arm32 and arm64 matrix entries with appropriate toolchains
- Add step to install ARM cross-compilation toolchains
- Add separate libmicrohttpd cross-compilation steps with caching
- Update configure step to use --host flag for cross-compilation
- Skip tests and cppcheck for cross-compilation builds (binaries
  cannot execute on x86_64 runners)

The existing COND_CROSS_COMPILE logic in configure.ac automatically
handles test exclusion during cross-compilation.

Closes #131

Subject: [PATCH 53/80] Fix ARM cross-compilation: use custom prefix for
 libmicrohttpd

The ARM cross-compiler doesn't search /usr/local by default. Install
libmicrohttpd to a workspace-local sysroot and pass CPPFLAGS/LDFLAGS
to libhttpserver's configure to find the headers and libraries.

Subject: [PATCH 54/80] Add client certificate authentication and SNI callback
 support

Add convenience methods for extracting client certificate information
from TLS connections (mTLS) and Server Name Indication (SNI) callback
support for hosting multiple certificates on a single server.

Client certificate methods added to http_request (requires GnuTLS):
- has_client_certificate() - check if client cert present
- get_client_cert_dn() - subject Distinguished Name
- get_client_cert_issuer_dn() - issuer DN
- get_client_cert_cn() - Common Name from subject
- is_client_cert_verified() - certificate chain verification status
- get_client_cert_fingerprint_sha256() - hex-encoded SHA-256 fingerprint
- get_client_cert_not_before() / get_client_cert_not_after() - validity times

SNI callback support (requires libmicrohttpd 0.9.71+):
- sni_callback() builder method on create_webserver
- Callback receives server name from TLS ClientHello
- Returns cert/key pair for the requested hostname

Closes #133

+### Using Client Certificate Authentication (mTLS)
+Client certificate authentication (also known as mutual TLS or mTLS) provides strong authentication by requiring clients to present X.509 certificates during the TLS handshake. This is the most secure authentication method as it verifies client identity cryptographically.
+
+To enable client certificate authentication, configure your webserver with:
+1. `use_ssl()` - Enable TLS
+2. `https_mem_key()` and `https_mem_cert()` - Server certificate
+3. `https_mem_trust()` - CA certificate(s) to verify client certificates
+
+```cpp
+    #include <httpserver.hpp>
+
+    using namespace httpserver;
+
+    class secure_resource : public http_resource {
+    public:
+        std::shared_ptr<http_response> render_GET(const http_request& req) {
+            // Check if client provided a certificate
+            if (!req.has_client_certificate()) {

+            }
+
+            // Check if certificate is verified by our CA
+            if (!req.is_client_cert_verified()) {
+                return std::make_shared<string_response>(
+                    "Certificate not verified", 403, "text/plain");
+            }
+
+            // Extract certificate information
+            std::string cn = req.get_client_cert_cn();           // Common Name

+            time_t not_after = req.get_client_cert_not_after();

+                "Welcome, " + cn + "!", 200, "text/plain");

+    };

+
+        secure_resource sr;
+        ws.register_resource("/secure", &sr);
+        ws.start(true);
+
+        return 0;
+    }
+```
+
+Available client certificate methods (require GnuTLS support):
+- `has_client_certificate()` - Check if client presented a certificate
+- `get_client_cert_dn()` - Get the subject Distinguished Name
+- `get_client_cert_issuer_dn()` - Get the issuer Distinguished Name
+- `get_client_cert_cn()` - Get the Common Name from the subject
+- `is_client_cert_verified()` - Check if the certificate chain is verified

+- `get_client_cert_not_before()` - Get certificate validity start time
+- `get_client_cert_not_after()` - Get certificate validity end time

+To test with curl:
+
+    # With client certificate
+    curl -k --cert client_cert.pem --key client_key.pem https://localhost:8443/secure
+
+    # Without client certificate (will be rejected)
+    curl -k https://localhost:8443/secure
+
+You can also check this example on [github](https://github.com/etr/libhttpserver/blob/master/examples/client_cert_auth.cpp).
+
+### Server Name Indication (SNI) Callback
+SNI allows a server to host multiple TLS certificates on a single IP address. The client indicates which hostname it's connecting to during the TLS handshake, and the server can select the appropriate certificate.
+
+To use SNI with libhttpserver, configure an SNI callback that returns the certificate/key pair for each server name:
+
+```cpp
+    #include <httpserver.hpp>
+    #include <map>
+
+    using namespace httpserver;
+
+    // Map of server names to cert/key pairs
+    std::map<std::string, std::pair<std::string, std::string>> certs;
+
+    // SNI callback - returns (cert_pem, key_pem) for the requested server name
+    std::pair<std::string, std::string> sni_callback(const std::string& server_name) {
+        auto it = certs.find(server_name);
+        if (it != certs.end()) {
+            return it->second;
+        }
+        return {"", ""};  // Use default certificate
+    }
+
+    int main() {
+        // Load certificates for different hostnames
+        certs["www.example.com"] = {load_file("www_cert.pem"), load_file("www_key.pem")};
+        certs["api.example.com"] = {load_file("api_cert.pem"), load_file("api_key.pem")};
+
+        webserver ws = create_webserver(443)
+            .use_ssl()

+/**
+ * Example demonstrating client certificate (mTLS) authentication.
+ *
+ * This example shows how to:
+ * 1. Configure the server to request client certificates
+ * 2. Extract client certificate information in request handlers
+ * 3. Implement certificate-based access control
+ *
+ * To test this example:
+ *
+ * 1. Generate server certificate and key:
+ *    openssl req -x509 -newkey rsa:2048 -keyout server_key.pem -out server_cert.pem \
+ *        -days 365 -nodes -subj "/CN=localhost"
+ *
+ * 2. Generate a CA certificate for client certs:
+ *    openssl req -x509 -newkey rsa:2048 -keyout ca_key.pem -out ca_cert.pem \
+ *        -days 365 -nodes -subj "/CN=Test CA"
+ *
+ * 3. Generate client certificate signed by the CA:
+ *    openssl req -newkey rsa:2048 -keyout client_key.pem -out client_csr.pem \
+ *        -nodes -subj "/CN=Alice/O=Engineering"
+ *    openssl x509 -req -in client_csr.pem -CA ca_cert.pem -CAkey ca_key.pem \
+ *        -CAcreateserial -out client_cert.pem -days 365
+ *
+ * 4. Run the server:
+ *    ./client_cert_auth
+ *
+ * 5. Test with curl using client certificate:
+ *    curl -k --cert client_cert.pem --key client_key.pem https://localhost:8443/secure
+ *
+ *    Or without a certificate (will be denied):
+ *    curl -k https://localhost:8443/secure

Subject: [PATCH 55/80] Fix test: add client certificate files to
 AC_CONFIG_FILES

The client_cert.pem and client_key.pem files need to be copied to the
build directory during configure, similar to how other test certificate
files are handled.

Subject: [PATCH 56/80] Fix HTTPS test pattern: use try-catch instead of
 checking start() return value

The webserver::start(false) method returns false when started successfully
in non-blocking mode (by design). The tests were incorrectly interpreting
this as a failure. Fixed by catching the exception that's thrown when
the server actually fails to start.

Also regenerated test certificates with valid dates (the old ones expired
in 2009).

Changes:
- Fix https_webserver, tls_session_getters, and all client_cert tests
- Regenerate cert.pem, key.pem, client_cert.pem, client_key.pem

Subject: [PATCH 57/80] Add test for client cert methods on non-TLS requests

This test exercises all client certificate convenience methods on a
plain HTTP (non-TLS) connection, verifying they return appropriate
empty/false values when no TLS session is present.

This ensures the early-return code paths in the client certificate
methods are covered even when HTTPS tests may not run in all CI
environments.

Subject: [PATCH 58/80] Fix tests that incorrectly check start(false) return
 value

webserver::start(false) always returns false for non-blocking mode
(returns value_onclose which is only set true for blocking mode).
Tests were checking `if (started)` which never executed the test code.

Changed affected tests to:
- Use try-catch for exception handling
- Check ws.is_running() instead of the return value
- Handle dual_stack curl failures gracefully (may not be available)

This fixes coverage for client cert and SNI tests that were silently
skipping without actually testing the functionality.

Subject: [PATCH 59/80] Add tests for client certificate edge cases

- client_cert_no_cn: Tests certificate without Common Name field,
  covering the cn_size == 0 branch in get_client_cert_cn()
- client_cert_untrusted: Tests certificate not in trust store,
  covering the status != 0 branch in is_client_cert_verified()

Also adds the new test certificate files to configure.ac.

Subject: [PATCH 60/80] Document new client certificate and SNI methods in
 README

Add to TLS/HTTPS configuration section:
- sni_callback() builder method for SNI support

Add to Parsing Requests section:
- has_client_certificate()
- get_client_cert_dn()
- get_client_cert_issuer_dn()
- get_client_cert_cn()
- is_client_cert_verified()
- get_client_cert_fingerprint_sha256()
- get_client_cert_not_before()
- get_client_cert_not_after()

Also fixed typo: "am underlying" -> "an underlying"

 * _.https_mem_trust(**const std::string&** filename):_ String representing the path to a file containing the CA certificate to be used by the HTTPS daemon to authenticate and trust clients certificates. The presence of this option activates the request of certificate to the client. The request to the client is marked optional, and it is the responsibility of the server to check the presence of the certificate if needed. Note that most browsers will only present a client certificate only if they have one matching the specified CA, not sending any certificate otherwise.
 * _.https_priorities(**const std::string&** priority_string):_ SSL/TLS protocol version and ciphers. Must be followed by a string specifying the SSL/TLS protocol versions and ciphers that are acceptable for the application. The string is passed unchanged to gnutls_priority_init. If this option is not specified, `"NORMAL"` is used.
 * _.psk_cred_handler(**psk_cred_handler_callback** handler):_ Sets a callback function for TLS-PSK (Pre-Shared Key) authentication. The callback receives a username and should return the corresponding hex-encoded PSK, or an empty string if the user is unknown. This option requires `use_ssl()`, `cred_type(http::http_utils::PSK)`, and an appropriate `https_priorities()` string that enables PSK cipher suites. PSK authentication allows TLS without certificates by using a shared secret key.
+* _.sni_callback(**sni_callback_t** callback):_ Sets a callback function for SNI (Server Name Indication) support. The callback receives the server name requested by the client and should return a `std::pair<std::string, std::string>` containing the PEM-encoded certificate and key for that server name. Return empty strings to use the default certificate. Requires libmicrohttpd 0.9.71+ with GnuTLS.

Takes in input the `realm` of validity of the authentication, the `password` as known to the server to compare against, the `nonce_timeout` to indicate how long the nonce is valid and `reload_nonce` a boolean that will be set by the method to indicate a nonce being reloaded. The method returns `true` if the authentication is valid, `false` otherwise.

Subject: [PATCH 61/80] Refactor client cert methods with RAII and fix security
 issues

- Add scoped_x509_cert RAII wrapper to eliminate code duplication
  across 6 certificate extraction methods
- Add null check in get_tls_session() to prevent null pointer
  dereference when MHD_get_connection_info returns nullptr
- Fix TOCTOU race condition in SNI credential caching by re-checking
  cache after acquiring exclusive lock

Subject: [PATCH 62/80] Optimize per-request critical path performance

- Replace istringstream-based string_split with manual loop (string_utilities.cpp)
- Fix http_unescape: parse hex chars directly without substr allocations (http_utils.cpp)
- Flatten unique_ptr<string> members in modded_request to plain std::string,
  eliminating 2 heap allocations per request (modded_request.hpp, webserver.cpp)
- Fix strcmp/strcasecmp inconsistency: all HTTP method dispatch now uses
  case-sensitive strcmp per RFC 7230 (webserver.cpp)
- Optimize set_method: skip unnecessary copy+uppercase since MHD provides
  method strings in uppercase per spec (http_request.cpp)
- Cache get_path_pieces() result on first access to avoid re-tokenization
  on every call (http_request.hpp)
- Separate exact vs parameterized routes at registration time; only scan
  parameterized routes on regex fallback (webserver.hpp, webserver.cpp)
- Add shared LRU cache (256 entries) for URL-to-endpoint route matches
  to avoid repeated regex matching (webserver.hpp, webserver.cpp)
- Optimize standardize_url to modify in-place instead of creating extra
  copies (http_utils.cpp)

Subject: [PATCH 63/80] Fix validation findings: bounds check, DRY, const refs,
 empty guard

- Add bounds checking for url_pieces[chunks[i]] to prevent potential
  buffer overflow when cached endpoint chunks don't match request pieces
- Extract URL parameter extraction from cache hit/miss paths into single
  block after match resolution (DRY fix)
- Use const references for vectors instead of by-value copies to avoid
  heap allocations under cache lock
- Add empty-string guard to standardize_url before calling back()
- Extract ensure_path_pieces_cached() helper to deduplicate caching logic
  in get_path_pieces() and get_path_piece()
- Add RFC 7230 comment documenting case-sensitive strcmp intent

Subject: [PATCH 64/80] Fix use-after-free: copy cache data while holding lock

The matched_ep pointer referenced data inside route_cache_list that
could be invalidated by another thread (via invalidate_route_cache or
LRU eviction) after the cache mutex was released.

Fix by copying url_pars and chunk_positions vectors while holding the
cache lock, so parameter extraction afterwards uses owned data.
For cache miss path, the registered_resources_mutex shared lock is
still held so direct reference is safe, but copy for consistency.

Subject: [PATCH 65/80] Fix race condition in unregister_resource cache
 invalidation

Move route cache invalidation inside registered_resources_mutex lock
in unregister_resource() to prevent use-after-free when threads
retrieve cached resource pointers during unregistration.

Also invalidate route cache on register_resource() for correctness
when resources are dynamically registered at runtime.

Add threading model documentation to http_request lazy caching.

The cached libmicrohttpd build has hardcoded GnuTLS include paths from

the current runner, gnutls/gnutls.h is not found at the old path.
Bumping the cache key forces a fresh build.

coverage report complete while still logging the issue.

Subject: [PATCH 71/80] Fix custom_socket test failure under Valgrind on Ubuntu
 24.04

Set SO_REUSEADDR before bind() so the port can be reused when still in
TIME_WAIT from prior tests, and connect to 127.0.0.1 instead of
localhost to avoid IPv6 resolution mismatch with the IPv4-only socket.

+* Add your entry under the **first** `Version X.Y.Z` header at the top of `ChangeLog`.
+* Use a tab-indented, one-line summary of each change:
+  ```
+  	Added support for new feature X.
+  ```
+* If your change spans multiple lines, indent continuation lines with two tabs:
+  ```
+  	Fixed a bug where long descriptions would cause the parser to
+  		fail on multi-line input.
+  ```
+* Changes that only touch files in `.github/`, `*.md` in the repository root, `.gitignore`, or `CPPLINT.cfg` are exempt from the ChangeLog requirement.

Subject: [PATCH 73/80] Fix 9 security vulnerabilities found in audit

- Fix path traversal in file uploads: sanitize filenames to basename,
  reject ".." and "." when generate_random_filename_on_upload is off
- Fix TOCTOU race in file_response: replace stat-then-open with
  open-then-fstat; add O_NOFOLLOW on non-Windows
- Fix FD leaks in file_response: close fd on lseek failure and
  zero-size file path
- Fix NULL deref in answer_to_connection: check conninfo before use
- Fix uninitialized _file_size in file_info (default to 0)
- Fix auth skip path bypass: normalize path (resolve ".." segments)
  before comparing against skip paths
- Fix free() vs MHD_free() for digest auth username
- Fix unchecked write error during file upload

Subject: [PATCH 75/80] FEATURE-bauth-conditional-compile: Implementation
 complete

Add HAVE_BAUTH conditional compilation for basic authentication,
mirroring the existing HAVE_DAUTH pattern. This allows libhttpserver
to build against libmicrohttpd installations that lack basic auth
support.

Changes:
- configure.ac: Auto-detect MHD_queue_basic_auth_fail_response,
  define HAVE_BAUTH flag and AM_CONDITIONAL, add to summary output
- src/httpserver/basic_auth_fail_response.hpp: Guard with #ifdef HAVE_BAUTH
- src/basic_auth_fail_response.cpp: Guard with #ifdef HAVE_BAUTH
- src/httpserver.hpp: Conditionally include basic_auth_fail_response.hpp
- src/httpserver/http_request.hpp: Guard get_user(), get_pass(),
  fetch_user_pass() declarations and username/password cache fields
- src/http_request.cpp: Guard fetch_user_pass(), get_user(), get_pass()
  implementations and basic auth output in operator<<
- src/httpserver/create_webserver.hpp: Guard basic_auth()/no_basic_auth()
  methods and _basic_auth_enabled member
- src/httpserver/webserver.hpp: Guard basic_auth_enabled member
- src/webserver.cpp: Guard basic_auth_enabled initialization
- src/Makefile.am: Make basic_auth_fail_response conditional on HAVE_BAUTH
- examples/Makefile.am: Guard basic_authentication and
  centralized_authentication examples behind HAVE_BAUTH
- test/integ/authentication.cpp: Guard basic auth tests with HAVE_BAUTH
- test/unit/create_webserver_test.cpp: Guard basic_auth builder test

From: Sebastiano Merlino <sebastiano@hey.com>
Date: Thu, 19 Feb 2026 12:15:17 -0800
Subject: [PATCH 76/80] Add HAVE_BAUTH guards to remaining files missed in
 initial commit

Guard basic auth references in ws_start_stop.cpp, basic.cpp,
create_test_request_test.cpp, create_test_request.hpp, and
create_test_request.cpp that would fail to compile when
libmicrohttpd lacks basic auth support.

Subject: [PATCH 79/80] Add documentation and example for serving binary data
 from memory

The existing string_response already supports binary content (std::string
can hold arbitrary bytes), but this was not documented or demonstrated
anywhere. This gap caused users to believe a new response type was needed
(see PR #368).

- Add a note to the README's string_response description clarifying
  binary data support
- Add a new "Serving binary data from memory" section with inline example
- Add examples/binary_buffer_response.cpp as a complete, buildable example
  that serves a PNG image from an in-memory buffer
- Register the new example in examples/Makefile.am

 As seen in the documentation of [http_resource](#the-resource-object), every extensible method returns in output a `http_response` object. The webserver takes the responsibility to convert the `http_response` object you create into a response on the network.
 
 There are 5 types of response that you can create - we will describe them here through their constructors:
-* _string_response(**const std::string&** content, **int** response_code = `200`, **const std::string&** content_type = `"text/plain"`):_ The most basic type of response. It uses the `content` string passed in construction as body of the HTTP response. The other two optional parameters are the `response_code` and the `content_type`. You can find constant definition for the various response codes within the [http_utils](https://github.com/etr/libhttpserver/blob/master/src/httpserver/http_utils.hpp) library file.
+* _string_response(**const std::string&** content, **int** response_code = `200`, **const std::string&** content_type = `"text/plain"`):_ The most basic type of response. It uses the `content` string passed in construction as body of the HTTP response. The other two optional parameters are the `response_code` and the `content_type`. You can find constant definition for the various response codes within the [http_utils](https://github.com/etr/libhttpserver/blob/master/src/httpserver/http_utils.hpp) library file. Note that `std::string` can hold arbitrary binary data (including null bytes), so `string_response` is also the right choice for serving binary content such as images directly from memory — simply set an appropriate `content_type` (e.g., `"image/png"`).
 * _file_response(**const std::string&** filename, **int** response_code = `200`, **const std::string&** content_type = `"text/plain"`):_ Uses the `filename` passed in construction as pointer to a file on disk. The body of the HTTP response will be set using the content of the file. The file must be a regular file and exist on disk. Otherwise libhttpserver will return an error 500 (Internal Server Error). The other two optional parameters are the `response_code` and the `content_type`. You can find constant definition for the various response codes within the [http_utils](https://github.com/etr/libhttpserver/blob/master/src/httpserver/http_utils.hpp) library file.
 * _basic_auth_fail_response(**const std::string&** content, **const std::string&** realm = `""`, **int** response_code = `200`, **const std::string&** content_type = `"text/plain"`):_ A response in return to a failure during basic authentication. It allows to specify a `content` string as a message to send back to the client. The `realm` parameter should contain your realm of authentication (if any). The other two optional parameters are the `response_code` and the `content_type`. You can find constant definition for the various response codes within the [http_utils](https://github.com/etr/libhttpserver/blob/master/src/httpserver/http_utils.hpp) library file.

It allows to specify a `content` string as a message to send back to the client. The `realm` parameter should contain your realm of authentication (if any). The `opaque` represents a value that gets passed to the client and expected to be passed again to the server as-is. This value can be a hexadecimal or base64 string. The `reload_nonce` parameter tells the server to reload the nonce (you should use the value returned by the `check_digest_auth` method on the `http_request`. The other two optional parameters are the `response_code` and the `content_type`.

+### Serving binary data from memory
+`string_response` is not limited to text — it can serve arbitrary binary content directly from memory. This is useful when you have data in a buffer at runtime (e.g., from a camera, an image processing library, or a database) and want to serve it without writing to disk.
+
+```cpp
+    #include <httpserver.hpp>
+
+    using namespace httpserver;
+
+    class image_resource : public http_resource {
+    public:
+        std::shared_ptr<http_response> render_GET(const http_request&) {
+            // binary_data could come from a camera capture, image library, etc.
+            std::string binary_data = get_image_bytes_from_camera();
+
+            return std::make_shared<string_response>(
+                    std::move(binary_data), 200, "image/jpeg");
+        }
+    };
+
+    int main() {
+        webserver ws = create_webserver(8080);
+
+        image_resource ir;
+        ws.register_resource("/image", &ir);
+        ws.start(true);
+
+        return 0;
+    }
+```
+To test the above example, you could run the following command from a terminal:
+
+    curl -o image.jpg http://localhost:8080/image
