+# curl/libcurl CMake script

+
+# TODO:
+# The output .so file lacks the soname number which we currently have within the lib/Makefile.am file
+# Add full (4 or 5 libs) SSL support
+# Add INSTALL target (EXTRA_DIST variables in Makefile.am may be moved to Makefile.inc so that CMake/CPack is aware of what's to include).
+# Add CTests(?)
+# Check on all possible platforms
+# Test with as many configurations possible (With or without any option)
+# Create scripts that help keeping the CMake build system up to date (to reduce maintenance). According to Tetetest:
+#  - lists of headers that 'configure' checks for;
+#  - curl-specific tests (the ones that are in m4/curl-*.m4 files);
+#  - (most obvious thing:) curl version numbers.
+# Add documentation subproject
+#
+# To check:
+# (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not.
+# (From Daniel Stenberg) The gcc command line use neither -g nor any -O options. As a developer, I also treasure our configure scripts's --enable-debug option that sets a long range of "picky" compiler options.

-        called before any cookies are set.
-
-int cookies_set(struct CookieInfo *cookie, char *cookie_line);
-
-        The 'cookie_line' parameter is a full "Set-cookie:" line as
-        received from a server.
-
-        The function need to replace previously stored lines that this new
-        line superceeds.
-
-        It may remove lines that are expired.
-
-        It should return an indication of success/error.

-SENDING COOKIE INFORMATION
-==========================
-
-struct Cookies *cookie_getlist(struct CookieInfo *cookie,
-                               char *host, char *path, bool secure);
-
-        For a given host and path, return a linked list of cookies that
-        the client should send to the server if used now. The secure
-        boolean informs the cookie if a secure connection is achieved or
-        not.
-
-        It shall only return cookies that haven't expired.
-
-
-Example set of cookies:
-
-    Set-cookie: PRODUCTINFO=webxpress; domain=.fidelity.com; path=/; secure
-    Set-cookie: PERSONALIZE=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;

-    Set-cookie: FidOrder=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
-    domain=.fidelity.com; path=/; secure
-    Set-cookie: DisPend=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;

-    Set-cookie: FidDis=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
-    domain=.fidelity.com; path=/; secure
-    Set-cookie:

- * hostip.c explained
- * ==================
- *
- * The main COMPILE-TIME DEFINES to keep in mind when reading the host*.c
- * source file are these:
- *
- * CURLRES_IPV6 - this host has getaddrinfo() and family, and thus we use
- * that. The host may not be able to resolve IPv6, but we don't really have to
- * take that into account. Hosts that aren't IPv6-enabled have CURLRES_IPV4
- * defined.
- *
- * CURLRES_ARES - is defined if libcurl is built to use c-ares for
- * asynchronous name resolves. This can be Windows or *nix.
- *
- * CURLRES_THREADED - is defined if libcurl is built to run under (native)
- * Windows, and then the name resolve will be done in a new thread, and the
- * supported API will be the same as for ares-builds.
- *
- * If any of the two previous are defined, CURLRES_ASYNCH is defined too. If
- * libcurl is not built to use an asynchronous resolver, CURLRES_SYNCH is
- * defined.
- *
- * The host*.c sources files are split up like this:
- *
- * hostip.c   - method-independent resolver functions and utility functions
- * hostasyn.c - functions for asynchronous name resolves
- * hostsyn.c  - functions for synchronous name resolves
- * hostares.c - functions for ares-using name resolves
- * hostthre.c - functions for threaded name resolves
- * hostip4.c  - ipv4-specific functions
- * hostip6.c  - ipv6-specific functions
- *
- * The hostip.h is the united header file for all this. It defines the
- * CURLRES_* defines based on the config*.h and setup.h defines.

- * Highlights from RFC2616 section 3.6 say:
-
-   The chunked encoding modifies the body of a message in order to
-   transfer it as a series of chunks, each with its own size indicator,
-   followed by an OPTIONAL trailer containing entity-header fields. This
-   allows dynamically produced content to be transferred along with the
-   information necessary for the recipient to verify that it has
-   received the full message.
-
-       Chunked-Body   = *chunk
-                        last-chunk
-                        trailer
-                        CRLF
-
-       chunk          = chunk-size [ chunk-extension ] CRLF
-                        chunk-data CRLF
-       chunk-size     = 1*HEX
-       last-chunk     = 1*("0") [ chunk-extension ] CRLF
-
-       chunk-extension= *( ";" chunk-ext-name [ "=" chunk-ext-val ] )
-       chunk-ext-name = token
-       chunk-ext-val  = token | quoted-string
-       chunk-data     = chunk-size(OCTET)
-       trailer        = *(entity-header CRLF)
-
-   The chunk-size field is a string of hex digits indicating the size of
-   the chunk. The chunked encoding is ended by any chunk whose size is
-   zero, followed by the trailer, which is terminated by an empty line.

+
+/*
+ * NOTE 1:
+ * -------
+ *
+ * All checks done in this file are intentionally placed in a public
+ * header file which is pulled by curl/curl.h when an application is
+ * being built using an already built libcurl library. Additionally
+ * this file is also included and used when building the library.
+ *
+ * If compilation fails on this file it is certainly sure that the
+ * problem is elsewhere. It could be a problem in the curlbuild.h
+ * header file, or simply that you are using different compilation
+ * settings than those used to build the library.
+ *
+ * Nothing in this file is intended to be modified or adjusted by the
+ * curl library user nor by the curl library builder.
+ *
+ * Do not deactivate any check, these are done to make sure that the
+ * library is properly built and used.
+ *
+ * You can find further help on the libcurl development mailing list:
+ * https://cool.haxx.se/mailman/listinfo/curl-library/
+ *
+ * NOTE 2
+ * ------
+ *
+ * Some of the following compile time checks are based on the fact
+ * that the dimension of a constant array can not be a negative one.
+ * In this way if the compile time verification fails, the compilation
+ * will fail issuing an error. The error description wording is compiler
+ * dependent but it will be quite similar to one of the following:
+ *
+ *   "negative subscript or subscript is too large"
+ *   "array must have at least one element"
+ *   "-1 is an illegal array size"
+ *   "size of array is negative"
+ *
+ * If you are building an application which tries to use an already
+ * built libcurl library and you are getting this kind of errors on
+ * this file, it is a clear indication that there is a mismatch between
+ * how the library was built and how you are trying to use it for your
+ * application. Your already compiled or binary library provider is the
+ * only one who can give you the details you need to properly use it.

+============================
+
+struct CookieInfo *Curl_cookie_init(struct Curl_easy *data,
+                    const char *file, struct CookieInfo *inc, bool newsession);
+
+        Inits a cookie struct to store data in a local file. This is always
+        called before any cookies are set.
+
+struct Cookie *Curl_cookie_add(struct Curl_easy *data,
+                 struct CookieInfo *c, bool httpheader, char *lineptr,
+                 const char *domain, const char *path);
+
+        The 'lineptr' parameter is a full "Set-cookie:" line as
+        received from a server.
+
+        The function need to replace previously stored lines that this new
+        line superceeds.
+
+        It may remove lines that are expired.
+
+        It should return an indication of success/error.
+
+
+SENDING COOKIE INFORMATION
+==========================
+
+struct Cookies *Curl_cookie_getlist(struct CookieInfo *cookie,
+                                    char *host, char *path, bool secure);
+
+        For a given host and path, return a linked list of cookies that
+        the client should send to the server if used now. The secure
+        boolean informs the cookie if a secure connection is achieved or
+        not.
+
+        It shall only return cookies that haven't expired.
+
+
+Example set of cookies:
+
+    Set-cookie: PRODUCTINFO=webxpress; domain=.fidelity.com; path=/; secure
+    Set-cookie: PERSONALIZE=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/ftgw; secure
+    Set-cookie: FidHist=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/; secure
+    Set-cookie: FidOrder=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
+    domain=.fidelity.com; path=/; secure
+    Set-cookie: DisPend=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;

+ * Nasty internal details ahead...
+ *
+ * File curl_memory.h must be included by _all_ *.c source files
+ * that use memory related functions strdup, malloc, calloc, realloc
+ * or free, and given source file is used to build libcurl library.
+ * It should be included immediately before memdebug.h as the last files
+ * included to avoid undesired interaction with other memory function
+ * headers in dependent libraries.
+ *
+ * There is nearly no exception to above rule. All libcurl source
+ * files in 'lib' subdirectory as well as those living deep inside
+ * 'packages' subdirectories and linked together in order to build
+ * libcurl library shall follow it.
+ *
+ * File lib/strdup.c is an exception, given that it provides a strdup
+ * clone implementation while using malloc. Extra care needed inside
+ * this one. TODO: revisit this paragraph and related code.
+ *
+ * The need for curl_memory.h inclusion is due to libcurl's feature
+ * of allowing library user to provide memory replacement functions,
+ * memory callbacks, at runtime with curl_global_init_mem()
+ *
+ * Any *.c source file used to build libcurl library that does not
+ * include curl_memory.h and uses any memory function of the five
+ * mentioned above will compile without any indication, but it will
+ * trigger weird memory related issues at runtime.
+ *
+ * OTOH some source files from 'lib' subdirectory may additionally be
+ * used directly as source code when using some curlx_ functions by
+ * third party programs that don't even use libcurl at all. When using
+ * these source files in this way it is necessary these are compiled
+ * with CURLX_NO_MEMORY_CALLBACKS defined, in order to ensure that no
+ * attempt of calling libcurl's memory callbacks is done from code
+ * which can not use this machinery.
+ *
+ * Notice that libcurl's 'memory tracking' system works chaining into
+ * the memory callback machinery. This implies that when compiling
+ * 'lib' source files with CURLX_NO_MEMORY_CALLBACKS defined this file
+ * disengages usage of libcurl's 'memory tracking' system, defining
+ * MEMDEBUG_NODEFINES and overriding CURLDEBUG purpose.
+ *
+ * CURLX_NO_MEMORY_CALLBACKS takes precedence over CURLDEBUG. This is
+ * done in order to allow building a 'memory tracking' enabled libcurl
+ * and at the same time allow building programs which do not use it.
+ *
+ * Programs and libraries in 'tests' subdirectories have specific
+ * purposes and needs, and as such each one will use whatever fits
+ * best, depending additionally whether it links with libcurl or not.
+ *
+ * Caveat emptor. Proper curlx_* separation is a work in progress
+ * the same as CURLX_NO_MEMORY_CALLBACKS usage, some adjustments may
+ * still be required. IOW don't use them yet, there are sharp edges.

+ * hostip.c explained
+ * ==================
+ *
+ * The main COMPILE-TIME DEFINES to keep in mind when reading the host*.c
+ * source file are these:
+ *
+ * CURLRES_IPV6 - this host has getaddrinfo() and family, and thus we use
+ * that. The host may not be able to resolve IPv6, but we don't really have to
+ * take that into account. Hosts that aren't IPv6-enabled have CURLRES_IPV4
+ * defined.
+ *
+ * CURLRES_ARES - is defined if libcurl is built to use c-ares for
+ * asynchronous name resolves. This can be Windows or *nix.
+ *
+ * CURLRES_THREADED - is defined if libcurl is built to run under (native)
+ * Windows, and then the name resolve will be done in a new thread, and the
+ * supported API will be the same as for ares-builds.
+ *
+ * If any of the two previous are defined, CURLRES_ASYNCH is defined too. If
+ * libcurl is not built to use an asynchronous resolver, CURLRES_SYNCH is
+ * defined.
+ *
+ * The host*.c sources files are split up like this:
+ *
+ * hostip.c   - method-independent resolver functions and utility functions
+ * hostasyn.c - functions for asynchronous name resolves
+ * hostsyn.c  - functions for synchronous name resolves
+ * hostip4.c  - IPv4 specific functions
+ * hostip6.c  - IPv6 specific functions
+ *
+ * The two asynchronous name resolver backends are implemented in:
+ * asyn-ares.c   - functions for ares-using name resolves
+ * asyn-thread.c - functions for threaded name resolves
+
+ * The hostip.h is the united header file for all this. It defines the
+ * CURLRES_* defines based on the config*.h and curl_setup.h defines.

+ * it has a linked list with entries. So the hash only checks which list to

+ * (as that is what the DNS hash uses) but with 7000 connections that would
+ * make an average of 1000 nodes in each list to run through. I upped that to
+ * 97 slots (I believe a prime is suitable) and noticed a significant speed

+     work-arounds. The man page for this option states that SSL_OP_ALL enables
+     all the work-arounds and that "It is usually safe to use SSL_OP_ALL to
+     enable the bug workaround options if compatibility with somewhat broken
+     implementations is desired."
+
+     The "-no_ticket" option was introduced in Openssl0.9.8j. It's a flag to
+     disable "rfc4507bis session ticket support".  rfc4507bis was later turned
+     into the proper RFC5077 it seems: https://tools.ietf.org/html/rfc5077
+
+     The enabled extension concerns the session management. I wonder how often
+     libcurl stops a connection and then resumes a TLS session. also, sending
+     the session data is some overhead. .I suggest that you just use your
+     proposed patch (which explicitly disables TICKET).
+
+     If someone writes an application with libcurl and openssl who wants to
+     enable the feature, one can do this in the SSL callback.
+
+     SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option enabling allowed proper
+     interoperability with web server Netscape Enterprise Server 2.0.1 which
+     was released back in 1996.
+
+     Due to CVE-2010-4180, option SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG has
+     become ineffective as of OpenSSL 0.9.8q and 1.0.0c. In order to mitigate
+     CVE-2010-4180 when using previous OpenSSL versions we no longer enable
+     this option regardless of OpenSSL version and SSL_OP_ALL definition.
+
+     OpenSSL added a work-around for a SSL 3.0/TLS 1.0 CBC vulnerability
+     (https://www.openssl.org/~bodo/tls-cbc.txt). In 0.9.6e they added a bit to
+     SSL_OP_ALL that _disables_ that work-around despite the fact that
+     SSL_OP_ALL is documented to do "rather harmless" workarounds. In order to
+     keep the secure work-around, the SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS bit
+     must not be set.

- * is somewhat of a bottle neck. Its current implementation may be a bit too
- * limiting. It simply has a fixed-size array, and on each entry in the array
- * it has a linked list with entries. So the hash only checks which list to
- * scan through. The code I had used so for used a list with merely 7 slots
- * (as that is what the DNS hash uses) but with 7000 connections that would
- * make an average of 1000 nodes in each list to run through. I upped that to
- * 97 slots (I believe a prime is suitable) and noticed a significant speed
- * increase.  I need to reconsider the hash implementation or use a rather
- * large default value like this. At 9000 connections I was still below 10us
- * per call."

-
-   If a subjectAltName extension of type dNSName is present, that MUST

-   field in the Subject field of the certificate MUST be used. Although
-   the use of the Common Name is existing practice, it is deprecated and
-   Certification Authorities are encouraged to use the dNSName instead.
-
-   Matching is performed using the matching rules specified by
-   [RFC2459].  If more than one identity of a given type is present in
-   the certificate (e.g., more than one dNSName name, a match in any one
-   of the set is considered acceptable.) Names may contain the wildcard
-   character * which is considered to match any single domain name
-   component or component fragment. E.g., *.a.com matches foo.a.com but
-   not bar.foo.a.com. f*.com matches foo.com but not bar.com.
-
-   In some cases, the URI is specified as an IP address rather than a
-   hostname. In this case, the iPAddress subjectAltName must be present
