+API incompatibility
+-------------------
+
+V0.1.*: * First formal version of API
+
+V0.2.*: * worker_start takes a 'worker_t' as an additional parameter
+	(This enables to perform a wait-on-event instead of a busy waiting).
+        * worker_spawn doesn't take into a 'worker_t' anymore.
+	* worker_init takes an int as numWorker instead of an unsigned int.
+	* RBTREE pop method has been renamed into _pop_at (as it takes a key parameter).
+        * SNAPSHOT_DEF has been removed. use SNAPSHOT_SPSC_DEF
+        * array's _set_at2 has been replaced by array's _get_at.
+        The interface is similar to dict _get_at, making the API cleaner and more generic.
+            _set_at2(a,i,x) ==> set(*_get_at(a,i),x)
+        * DICT_SET:
+          - Rename method _set_at as _push
+        Since there is no key, it is a push method, not a _set_at method.
+          - Rename DICT_SET_DEF2 as DICT_SET_DEF
+        since it only requires one argument.
+          - The method _ref returns a pointer to the data,
+        instead of a pointer to a single tuple like other DICT_SET interface.
+          - The format of the output to character string as changed. 
+        * ALGO:
+          - Rename _contains as _contain_p
+        since it is a predicate '_p' and it shall be in infinitive form.
+          - Rename _map as _for_each (Standard name).
+        * M_PRINT_ARG & M_FPRINT_ARG don't put a final semicolon at the end
+        of their expansion anymore (cleaner and no longer needed with the
+        new available tools).
+        * For the TUPLE and the VARIANT
+        change name of _get_ ## field into _get_at_ ## fields
+        Since there is a name collision with other methods
+        if a field is named 'str'.
+        * Rename method _remove into _erase for dictionary & B+TREE (adding a compatibility layer) for API uniformization.
+        The provided _remove doesn't use an iterator but a 'key', incompatible with the one of array or list.
+        But is like the one provided by the priority queue.
+        
+V0.3.*: * Remove B+TREE _remove method as it has been deprecated (use _erase instead)
+        * Remove DICT _remove method as it has been deprecated (use _erase instead)
+        * Make _it_to_p method of B+TREE / RB-TREE as deprecated (uses _it_until_p instead ).
+        * Deprecated buffer options BUFFER_BLOCKING* and BUFFER_UNBLOCKING*
+        as the _push_blocking and _pop_blocking functions can do the same and are more versatil.
+	* Iteration over the items of a dictionnary/tree returns const iterators for access through
+	OPLIST (impact: algorithm & M_EACH) as the IT_REF operator is no longer exported.
+	The _it_ref method is still defined and can be used, so you can still modify the values
+	but it won't be automatically used anymore (as the keys CANNOT be modified).
+	(Previously it generates incorrect algorithm when used with m-dict).
+
+V0.4.*: * The order of a list initialized using M_LET is reversed
+        to match what is done for ARRAY (and the C++ forward_list).
+        * Rename M_SKIP, M_KEEP & M_MID into M_SKIP_ARGS, M_KEEP_ARGS & M_MID_ARGS
+        due to conflict with glibc malloc.h (that defines M_KEEP for compatibility).
+        * Method write_string of m_serial expects a new argument (number of characters).
+        * Method _init_set2 of m-i-shared is removed.
+        * Operator _it_insert updates it_insertion iterator to reference the inserted element.
+        * Dereference Type of an iterator of a dict / B+Tree is suffixed by _itref_t instead of _type_t.
+        * Rename TUPLE _init_set2 in _init_emplace & _set2 in _emplace.
+        * Rename Priority Queue method _update_further in _update.
+        
+V0.5.*: * M_INVERT is renamed into M_REVERSE to be more coherent with the REVERSE operator.
+          M_INVERT is marked as obsolete.
+        * Remove _it_to_p method of B+TREE / RB-TREE as it has been deprecated.
+        * Remove ALGO_INIT_VA & M_ALG0_LET_INIT_VAI of m-algo as it has been deprecated (Use of M_LET instead).
+        * Some Internal name of user modifiable macros have been renamed to be properly 
+        customizable by the user.
+        * Rename M_HASH_SEED into M_USE_HASH_SEED (as it is a user macro).
+        * M_LET: for initialization of variable with arguments, if there is only one argument, 
+        it will default to use INIT_SET instead of INIT_WITH.
+        ==> Encapsulate the argument between () to force use of INIT_WITH.
+        * Remove of UPDATE operator. Use of SET for RBTREE or ADD for DICT instead.
+        * Make the _clean suffix for reseting the container to empty deprecated. Use new _reset suffix instead.
+        * Make the _get_at suffix for always getting a value deprecated. Use new _safe_get suffix instead.
+	* Rename CLEAN operator in RESET operator.
+	* Rename GET_SET_KEY operator in SAFE_GET_KEY operator.
+	
+V0.6.*: * Rename M_DEFAULT_OPLIST in M_BASIC_OPLIST
+        * Remove experimental macro M_IF_DEFAULT1.
+        * Remove M_INVERT
+        * String functions with _str suffix for C strings have been renamed with _cstr suffix (like string_cat_str ==> m_string_cat_cstr)
+        Note: the compatible layer still keeps the old naming,
+        so except if you are using the prefixed version of the strings
+        or the bounded strings API, you won't need to upgrade your code.
+        
+V0.7.2: * Rename m-mutex.h header in m-thread.h
+
+V0.7.3 : * DICT_STOREHASH_DEF2 / DICT_STOREHASH_DEF2_AS are deprecated.
+          Use DICT_DEF2 / DICT_DEF2_AS
+          
+V0.8.0 : * Memory interface massive compatibility break to allow more efficient integration of custom allocators.
+           The prototypes of NEW / DEL REALLOC / FREE operators are incompatible:
+           * Add the old number of elements of the array as argument of REALLOC
+           * Add the number of elements of the array and its base type as arguments of FREE.
+           * Add the context argument (which shall be ignored in not specific build)
+           (You can ignore the new arguments which are only hints provided to memory functions).
+           Also impact M_MEMORY_NEW / M_MEMORY_DEL / M_MEMORY_REALLOC & M_MEMORY_FREE
+           M_MEMORY_FULL: replace the failed size allocation size argument into the base type and the number of elements that failed to be allocated.
+         * m-buffer:
+           * non-thread safe queue & stack are moved into their dedicated header (m-queue) 
+           * BUFFER_THREAD_UNSAFE policy is no longer supported.
+           * Disabling BUFFER_BLOCKING policy is no longer supported (default policy is now forced).
+           * _push / _pop now returns now void like other containers instead of a bool (it was undocumented)
+         * Remove MEMPOOL support from list & R/B tree
+         * m-mempool: Header is obsolete (and no longer useful at all as lists & RB Tree no longer can use it. To remove). Use new M_USE_CONTEXT interface to pass local pool context.
+         * M*LIB becomes stricter for the INIT_MOVE operator:
+           The Emulation layer using CLEAR+INIT_SET methods, when there is no INIT_MOVE operator, has been removed:
+           either default INIT_MOVE operator (operator '=') is working, or a method is provided for INIT_MOVE or it is disabled.
+           If it is an array of size 1, you can use M_COPY_A1_DEFAULT as a default method.
+           (It's because supporting emulation layer with new memory context parameter was complicated)
+	 * Remove obsole headers: m-c-mempool, m-mempool, m-shared, m-i-shared, -mconcurrent
+	 
+V0.8.1 : * m-algo: Update interface of _transform to be more flexible: adding user context pointer, and filtering of the input elements.
+         * m-algo: Update interface of _reduce to be more user friendly: return value indicates if the reduction is empty or not.
+         * m-algo: Rename _map_reduce into _transform_reduce and update its interface to be more flexible: adding user context pointer, and filtering of the input elements and return value indicates if the reduction is empty or not.
+         * Rename _push_raw method by _push_back_raw for all containers (clearer on the semantic)

+Atomic library
+==============
+
+For the targets armel, m68k, mips, mipsel, powerpc, powerpcspe or sh4,

+
+make check LDFLAGS="-pthread -latomic"
+
+since 'atomic' library is not automatically included for 32 bits systems.
+
+
+Cross compilation
+=================
+
+There is no need to cross compile the library as it is a header only library.
+
+However if you want to run the tests with a cross-compiler, do like the following

+and run the test suite with wine:
+
+        make CC="i586-mingw32msvc-gcc -std=c99 -DWINVER=0x600 -D_WIN32_WINNT=0x600" LOG_COMPILER=wine check
+
+
+Handling issues
+===============
+
+Issues are opened in the bug tracker of the project (typically https://github.com/P-p-H-d/mlib/issues )
+
+If the issue cannot be taken into account quickly and are long term,
+it should be moved into the long term issues included in the repository:
+https://github.com/P-p-H-d/mlib/blob/master/doc/ISSUES.org
+This is a file in ORG mode: the issues are created with the proper tags.
+
+The original issue in the tracker can then be closed with the issuer agreement.
+
+This will have the following gains:
+
+- no hard dependencies on any bug tracking infrastructure (can be migrated easily). 
+- a release will automatically contain all its open problem reports.
+
+Once one issue of ISSUES.org is taken into account,
+its state shall be changed to DONE (the issue shall not be removed).
+
+
+Debugging
+=========
+
+Debugging the library can be quite difficult
+as it performs heavy preprocessing expansion
+and expands all code in one line.
+Different strategy for debugging the library itself are still possible:
+
+1) Good old printf.
+Add printf of interresting values in the debugged function.
+
+
+2) Preprocess the library and then compile the preprocessed file like this:
+
+          cc -std=c99 -E test-file.c > test-file.i
+          perl -pi -e 's/;/;\n/g' test-file.i
+          cc -std=c99 -c -Wall test-file.i
+
+ The resulting executable can be debugged much more easily.
+
+
+3) To debug the preprocessing itself, the Boot Wave library can be used
+and in particular the [wave driver](https://www.boost.org/doc/libs/1_71_0/libs/wave/doc/wave_driver.html)
+
+ Add in the code the following pragmas around the code to debug:
+
+     	  #pragma wave trace(enable)  
+     	  ARRAY_DEF (array_charp, char *)
+     	  #pragma wave trace(disable)
+
+Run the wave driver:
+
+    	 ./wave ex-array01.c -I .. --c99 -t test.trace
+
+The different expansion performed by the library are described in test.trace
+
+Coding rules
+============
+
+* Use of non standard C shall be protected under a specific compiler test,
+  so that the library remains compatible with a strict C99 compiler.
+
+* C11 features shall be optional.
+
+* Use 'make format' to format the header files properly.
+
+* External types shall be suffixed by _t and in lower case
+  but shall be optional if the user doesn't want then.
+
+* Internal types shall be suffixed by _ct and in lower case
+  (as confidential types)
+
+* External / Internal functions shall be in lower case.
+
+* External / Internal macros shall be in upper case.
+
+* Internal macros / functions shall be prefixed by m_<container>
+  with container is the name of the container with one letter transformed:
+      o --> 0
+      e --> 3
+      i --> 1
+      y --> 4
+  This prevents the automatic completion to work when the user starts writing its function.
+
+* Test functions shall be predicated and be suffixed by '_p'

+==========================================================
+
+* DONE #34 : Pass old size arguments to memory allocator        :ENHANCEMENT:
+
+** State
+
+Some custom allocators don't store the old size of an object to maximize memory usage
+used by the allocated objects. On realloc, they need the old size argument.
+This is inline with the GMP allocator which provides  the old size argument.
+There is no difficulty in the data structure to compute the old size of the object
+(it is quite easily available).
+It is needed for REALLOC operator (and FREE)
+
+** Solution #1
+
+Add the oldsize argument to the REALLOC and FREE operators.
+
+** Solution #2
+
+Create a local variable m_local_old_size before calling the REALLOC or FREE operators
+Modify GAIA interface to link OLDSIZE patttern to m_local_old_size
+Need to handle the warnings correctly.
+
+** Tradeof analysis
+
+Solution #1 is simpler but breaks API. However custom allocators are not common.
+Solution #2 keeps API as it is but increases code complexity by adding more hacks into the codebase.
+
+* TODO #33 : Handling of partially constructed object               :ANOMALY:
+** State
+
+Support of partially constructed object needs special code to handle it 
+correctly (register a correct cleanup function in case of exception).
+
+Current containers don't support such features.
+
+> NOTE: 
+ An exception for init_set supposes that the object is *not* initialized.
+ An exception for set supposes that the object *remains* initialized.
+ Some containers perform an init_set using init+set
+ others perform a set using a clear+init_set
+ The property of init_set (resp. set) is broken if an exception is raised in the set (resp. init_set):
+ the object is not let in the expected uninitialized (resp. initialized) state.
+
+** Actions
+
+Add such support in M*LIB containers. 
+Need to analyse each function for execption safety.
+
+It can be difficult. For example, for array _init_set
+function due to the copy of the object one per one. Each copied sub object
+may throw an exception, so we always need to have the container in a correct
+state so that it can be cleanup.
+
+* DONE #32 : User specialization fields in the container        :ENHANCEMENT:
+** State
+
+Some methods of a contained object may need to have some options that 
+are neither constant nor global, but are specialized in function of the container.
+
+For example, a memory handler may need a parameter which is needed to identify
+which pool of memory has to be used.
+
+** Plan:
+
+Add a new operator "CONTEXT" which is a type to be added in the 
+defined container. Then it can be accessed by the operator through an extension
+of the GAIA by adding support for identification of specialization like this:
+
+     ( CONTEXT( memory_pool_ref ),
+       NEW( API(NONE, memory_pool_alloc, CONTEXT, ARG1)),
+       DEL( API(NONE, memory_pool_free, CONTEXT, ARG1)) )
+
+** Open points:
+
+- How to get access to the specialization field of the container? 
+==> Define the "self" name as the name of the container for all methods? 
+- What to do when there are several containers for a method?
+==> self shall be the destination?
+
+- How to initialize the specialization field of the container? provide custom initialization functions? It seems to be the hard point.
+  Use GAIA interface and a local variable with force naming : m_local_context for example.
+
+** Proposed Solution:
+
+  New operator USER_CONTEXT created. If operator USER_CONTEXT exist:
+  + add a USER_CONTEXT user_data in the data structure.
+  + for INIT & INIT_WITH, add a new parameter to the function to pass the context to initialize
+  + for INIT_SET & INIT_MOVE & MOVE, initialize it with the source object (FIXME: This may not be what we want for INIT_SET if we want to copy an object from an allocator to another)
+  + for each functions that use an operator that may use the USER_CONTEXT, add a local variable m_local_context and initialize to the user context
+  ==> Limit user context to pointer or integer (Good enough)
+  + Expand GAIA interface to handle specially the term USER_CONTEXT: if it exists, expands it to m_local_context. The user will therefore be able to expand its operator with the user provided local context.
+  + Update OPLIST of data structure to change the call to INIT & INIT_WITH to use GAIA/USER_CONTEXT if the basic type has a USER_CONTEXT
+  + To be checked: EMPLACE_TYPE ?
+  + Create M_USING_CONTEXT to initialize a local variable m_local_context and initalize it with the user context to be used y the M_LET macro:
+      M_USING_CONTEXT(int *, &y) 
+      M_LET(x, object_t) {
+
+      }
+
+  Done in branch feature/user-data-v2 with a full working implementation for array
+
+** Solution limitation:
+
+ INIT & INIT_WITH interface change for the user. This however is an acceptable limitation.
+
+ Adding a user context to each data structure will increase a lot the size of the data structure in case of recursive data structures: For example, an array of string_t. Each string_t will need a user data context for it to work properly, so we'll need N*sizeof(user data context) memory just to make it work. This becomes even more problematic if we chain more data structures.
+ And in general, we use custom allocators to be faster and use less memory: this will defeat the purpose of custom allocators a lot.
+
+ Another limitation is that string_t / bitset_t are not supported correctly. We can make this change globally but it will prevent mixing different codebase that uses the string_t together (one expects a user context, the other not).
+ 
+** Alternative #1
+
+ Passing user context arguments to each function call seems to be a little bit better.
+ It might however reduces code optimization as one more register will be user everywhere in the calling chain, which may huge.
+
+** Alternative #2
+
+ The custom allocator could have a thread default allocator as a global variable (thread attribute). It seems to be a better solution, more scalable.
+ The custom allocator will need to be able to switch quickly between scrach arena and permanent arena. This seems to be easy.
+
+ However switching allocators puts a burden to the user: 
+ the user needs to properly be sure to call the destructor with the custom allocator set to be the same as when it was created.
+ This might not even be possible in case of exceptions.
+ 
+* TODO #31 : Uniformize parametrization options of containers   :ENHANCEMENT:
+
+** State 
+
+Currently in order to pass some parametrization of the containers,
+the parameters are passed to the generation macros through:
+
+- extra parameters of the macros,
+- special operators of the contained object oplist.
+
+The extra parameters of some generation macros break the uniformity
+of the interface.
+It is conceptually wrong to put some special operators of the contained object 
+that have only meanings for the container object.
+In case of adding new options, it break the existing interface or put another
+operator in the contained object oplist.
+
+
+The following parameters are used:
+
+- Fixed size of a queue (buffer / B+Tree),
+- Policy of a queue (buffer),
+- Type of the container, IT type of the container, Ref type of the iterator
+
+The following operators are used:
+
+- NEW / DEL / REALLOC / FREE
+- MEMPOOL / MEMPOOL_LINKAGE
+
+The following new options is planned:
+
+- Interface (See #28)
+- Extra parameter for memory allocation function 
+
+** Plan
+
+The M\_*\_DEF\_AS macros shall be changed like this:
+
+    M_*_DEF_AS(name, cont_oplist, type[, type_oplist])
+
+with cont\_oplist being the container oplist that gives parametrization to the container definition.
+The following operators are planned:
+
+- TYPE: to define the type of the container,
+- IT\_TYPE: to define the IT type of the container,
+- SUBTYPE: to define the type pointed by the iterator,
+- FIXED\_SIZE: to define the fixed size of a container,
+- POLICY: to define the policy of a container,
+- NEW / DEL / REALLOC / FREE: to define the memory interface,
+- MEMPOOL / MEMPOOL_LINKAGE: to request a definition of a specialized memory interface,
+- INTERFACE: to request a pure header definition, an implementation or both (see #28),
+- CONTEXT: to request an extra context parameter to add in the container.
+
+All operators should be optional.
+
+The NEW / DEL / REALLOC / FREE / MEMPOOL / MEMPOOL_LINKAGE won't have any effects anymore if defined in the contained object oplist.
+
+** Pro:
+
+- Uniformize interface
+
+** Con:
+
+- API breakage. It can be mitigated by providing an adaptating layer by prividing the new interface for M\_*\_DEF\_AS only
+and *\_DEF\_AS will provide a translation layer.
+
+* TODO #30 : Serialization rework                               :ENHANCEMENT:
+
+** State 
+Currently, each container supports 3 serialization methods:
+
+- old format to FILE 
+- old format to string
+- generic serialization 
+
+Generic serialiation connect the container format to the serialization object constraints.
+It is done through a vtable. As such there is a performance penality and it avoids proper inlining.
+It is however quite flexible and decouple the data structure from the serialization format.
+
+** Evolution
+
+Old format should be deprecated and the functions implemented it shall use the generic serialization interface.
+
+Serialization object shall provide a special OPLIST of serialization.
+For example M-CORE will provide OLD Format oplist and M-SERIAL-JSON will provide JSON format oplist.
+Each oplist will provide the suffix needed for the serialization, and the interface
+(see already existing interface).
+
+Then a container will generate specialized serialization methods for each provided oplist.
+
+** Pros:
+
+- Faster
+- In the M*LIB philosphy: much like other oplist usage.
+
+** Cons:
+
+- compatibility breakage.
+- increase code complexity.
+
+** Open point:
+
+- how can a user add a new serialization object? ==> See solution implemented by M-GENERIC.
+- Can we make a generic serialization object to support migration path? Seems possible.
+
+** Example
+

+* DONE #29 : Support of partial initialized object                  :ANOMALY:
+
+** State
+
+In case of exception during the construction of an object,
+if the object is partially constructed, there is no destructor to call.
+Therefore if there is some partially constructed object
+(with some fields already fully constructed), there will be some links.
+This is the same problem with C++
+
+** Proposition
+
+Provide new macros to perform the partial initialization before doing the remaining taf.
+Something like:
+
+    M_CHAIN_INIT( init_code, clear_code)
+
+or
+
+x is { string_t s; string_t d; int num; }
+
+void struct_init_set(struct_t x, const struct_t y)
+{
+    // First thing is Chained Initialization
+    M_CHAIN_INIT( string_init_set(x->s, y->s), string_clear(x->s) );
+    M_CHAIN_INIT( string_init_set(x->d, y->d), string_clear(x->d) );
+    // End of chain init
+    x->num = y->num;
+}
+
+M_CHAIN_INIT will push the clean code pretty much like M_LET.
+Everything else is done in M_LET: when the constructor fully returns,
+the index of the clean code to call is reset to its value before calling
+the constructor. It means that the partially initialized code will be removed
+from this stack before the clean method of the structure itself is pushed.
+
+If an exception is raised after a M_CHAIN_INIT, only the clean methods
+of the M_CHAIN_INIT are called.

+low bits = high bits of hash
+pointer to object { key, hash, value }
+

+
+Use of pointer to avoid moving object on GC.
+
+On AMD64, only 48 bits of 64 bits are really used for addressing data.

+In which case a complete new implementation will be needed
+Note: SIMD doesn't seem to be a win if not handled properly.
+Since the first guess of a good hashtable shall give the right entry > 90% of the time.

+* TODO #25 : Support of error return model for error handling.  :ENHANCEMENT:
+
+** State
+Find a way to support error return code for the API in case of allocation
+failure.
+
+** Analysis
+Any service that returns void shall return a "int" (or another type).
+In case of allocation failure, it shall return an error.
+M_CALL macro shall stop its execution if the service returns an error code
+and the error code represents an error (avoid rewritting everything)
+and throw back the error code (stopping the execution flow).
+
+Services returning already something shall not be modified but returns the error code embedded (like a NULL pointer).
+
+This model should be applied at the container level only and not globally.
+Different containers may need different levels of error handling.
+4 combinaison to take into account:
+
+==> ABORT on container / ABORT on used type: The current model
+==> ABORT on container / RETCODE on used type: Needs to abort on reported error.
+==> RETCODE on container / ABORT on used type: Nothing particular to note.
+==> RETCODE on container / RETCODE on used type: Forward retcode to caller.
+
+Find a way to make it while not making the code too complex 
+(try to keep as simple as possible).
+
+Using a specialized oplist for such containers (_OPLIST_RETCODE)
+using a specialized API for retcode:
+
+API_RET_*: that expands to
+
+     if (func(args) == 0) goto handler_exit_failure;
+
+Adding at the end of each service:
+     M_END_FUNCTION(cleanup_code) that expands to different cases:

+* DONE #23 : Strict MOVE semantic to clarify                    :ENHANCEMENT:
+
+** State
+
+Some type may need to have a force MOVE semantic (for example, they can store
+pointer to themselves). Currently the INIT_MOVE & MOVE operators are more
+a help for performance than a strict semantic usage.
+
+** ARRAY container constraint
+
+The ARRAY container doesn't support strict MOVE semantic for example.
+It is not a simple matter as it performs a realloc of the table, thus
+moving the data before they can be moved using MOVE. Two solutions:
+
+- New operator MOVE_SELF to fix a type after it has been moved.
+- If MOVE defined, force another table and then copy by hand the type. This will be slower and consumme more memory.
+
+** MOVE in OPLIST
+
+Proposal: do not export INIT_MOVE / MOVE operator in OPLIST if the MOVE operator is 
+compatible with a pure COPY semantic. An exported MOVE operator will tell 
+other containers than the type shall be carefully moved using the provided
+MOVE operator.
+
+For example for tuple, it shall
+
+- create an init_move operator if no one has disabled INIT_MOVE,
+- export the init_move operator if at least one has exported a INIT_MOVE and no one has disabled INIT_MOVE.
+
+** DO_INIT_MOVE operator
+
+DO_INIT_MOVE macro is also fully working for structure
+defined with [1] tricks but without an explicit INIT_MOVE / MOVE
+operators as it uses MOVE_DEFAULT which is not compatible.
+==> Analyse limitation and possible constraint usages.
+
+Being able to define a correct default for INIT_MOVE will be really good
+(compatible with trivial move copy).
+In such case, all INIT_MOVE & MOVE operators can be removed from oplist
+to only use the default, and theses operators can be disabled or defined
+only when really needed in the oplist.
+However creating a default INIT_MOVE macro seems problematic.
+If the type is typedef T t[1] then passing such an argument to a function, 
+will transform the argument to T*, and the type of the argument doesn't match
+what is expecting resulting in a move of the pointers, not a move of the design data.
+
+Defining this type seems possible with C11 _Generic and a TYPE in the oplist,
+but without C11 _Generic I don't see any way to define such macro
+and we still need to target C99 for such basic feature.
+
+Without a way to write such a macro, the ticket seems pretty much a dead end.

+
+#+BEGIN_SRC C
+        void shared_ptr_set_atomic(ptr a, atomic_ptr *ptr)

+#+END_SRC
+
+This prevents using NULL which obliges atomic shared pointer to point to a created object...

+
+The best parallel algorithm is still when there is as few synchronization as possible. A concurrent dictionary will fail at this and will result in average performance at best.
+The typical best case will be in RCU context (a lot of readers, few writers), so the interface shall be compatible with such structure.
+
+** Multiple locks within the dictionnary
+
+A potential implementation may be to request at initialization time the number of concurrent thread N.
+Create a static array of N dictionnary with N mutex. Then to access the data will perform :
+
+- compute hash of object,
+- access high bits of hash and select which dictionnary shall have the data,
+- lock it,
+- perform classic access to the data (check if the compiler can properly optimize the hash computation),
+- unlock it.
+
+The property of the hash shall allow a good dispersion of the data across multiple locks, reducing the constraints on the lock. This implementation could be build easily upon the already existent dictionary.
+
+To test.

+
+ Solution?
+ --------
+ 
+ Use of the concurrent pool (m-c-mempool) to allocate items.
+ The big table will only store pointers (+ part of hash in unused bits?) to such allocate items.
+ Atomic update is done by allocating a new node, update it, and atomicaly store it in the dict, putting the old one as logically deleted and to reclaim later.

+   
+   Some kind of "binary serialization" on the model of get_str/parse_str
