* Coding conventions
- integer types will be defined using types given in ~stdint.h~
- pointers are always initialized to ~NULL~
- when memory is freed, the pointer is set to ~NULL~
- ~assert.h~ should be used extensively
- variable names are in lower case
- ~#define~ constants are in upper case
- structs are suffixed by ~_s~
- types are suffixed by ~_t~
** Memory allocation
Memory allocation of structures can be facilitated by using the
following macro, which ensures that the size of the allocated
object is the same as the size of the data type pointed by the pointer.
#+begin_src c :tangle trexio_private.h
#define MALLOC(T) (T*) malloc (sizeof(T));
#define CALLOC(N,T) (T*) calloc ((N),sizeof(T));
#+end_src
When a pointer is freed, it should be set to ~NULL~.
This can be facilitated by the use of the following macro:
#+begin_src c :tangle trexio_private.h
#define FREE(X) { free(X) ; (X)=NULL; }
#+end_src
* Front end
All calls to TREXIO are thread-safe.
** Error handling
#+begin_src c :tangle trexio.h
typedef int32_t trexio_exit_code;
#define TREXIO_FAILURE ( (trexio_exit_code) -1 )
#define TREXIO_SUCCESS ( (trexio_exit_code) 0 )
#define TREXIO_INVALID_ARG_1 ( (trexio_exit_code) 1 )
#define TREXIO_INVALID_ARG_2 ( (trexio_exit_code) 2 )
#define TREXIO_INVALID_ARG_3 ( (trexio_exit_code) 3 )
#define TREXIO_INVALID_ARG_4 ( (trexio_exit_code) 4 )
#define TREXIO_INVALID_ARG_5 ( (trexio_exit_code) 5 )
#define TREXIO_END ( (trexio_exit_code) 10 )

#define TREXIO_ERRNO ( (trexio_exit_code) 12 )
#define TREXIO_INVALID_ID ( (trexio_exit_code) 20 )
#define TREXIO_ALLOCATION_FAILED ( (trexio_exit_code) 21 )
#define TREXIO_INVALID_NUM ( (trexio_exit_code) 22 )
#+end_src
** Back ends
#+begin_src c :tangle trexio.h
typedef int32_t back_end_t;
#define TREXIO_HDF5 ( (back_end_t) 0 )
#define TREXIO_TEXT ( (back_end_t) 1 )
#define TREXIO_JSON ( (back_end_t) 2 )
#define TREXIO_INVALID_BACK_END ( (back_end_t) 3 )
#+end_src
** Read/write behavior
Every time a reading function is called, the data is read from the
disk. If data needs to be cached, this is left to the user of the
library.
Writing to TREXIO files is done with transactions (all-or-nothing
effect) in a per-group fashion. File writes are attempted by
calling explicitly the flush function, or when the TREXIO file is
closed. If writing is impossible because the data is not valid, no
data is written.
The order in which the data is written is not necessarily consistent
with the order in which the function calls were made.
The TREXIO files are supposed to be opened by only one program at a
time: if the same TREXIO file is modified simultaneously by multiple
concurrent programs, the behavior is not specified.
** TREXIO file type
~trexio_s~ is the the main type for TREXIO files, visible to the users
of the library. This type is kept opaque, and all modifications to
the files will be necessarily done through the use of functions,
taking such a type as argument.
File creation and opening functions will return /TREXIO file handles/,
namely pointers to ~trexio_s~ types. All functions accessing to the
TREXIO files will have as a first argument the TREXIO file handle.
#+begin_src c :tangle trexio.h
typedef struct trexio_s trexio_t;
#+end_src
#+begin_src c :tangle trexio_s.h

char* file_name;
pthread_mutex_t thread_lock;
back_end_t back_end;
char mode;
char padding[7]; /* Ensures the proper alignment of back-ends */
};
#+end_src
** Polymorphism of the file handle
Polymorphism of the ~trexio_t~ type is handled by ensuring that the
corresponding types for all back ends can be safely casted to
~trexio_t~. This is done by making the back end structs start with
~struct trexio_s~:
#+begin_src c

* Back ends
TREXIO has multiple possible back ends:
- HDF5: The most efficient back-end, by default
- Text files: not to be used for production, but useful for debugging
- JSON: for portability
* File suffixes :noxport:

#+end_src
#+begin_src c :tangle trexio_s.h

#+end_src
* TODO Things to be done :noexport:
- [ ] Thread safety
- [ ] Error handling with errno
- [ ] HDF5 back-end
- [ ] JSON back-end
- [ ] Caching of the struct saving last modification date in structs
