Being able to indivually initialize individual modules was initially
"good", but at end it's putting complexities on users that would try
to "optimize" by doing just what they used, but in the end most people
would get them wrong, users would have to do lots of code and etc. At
the end it does not worth.
Most module init just register handful errors and log domains, so are
cheap. The exception is mempool users, that would dlopen() stuff, but
people that are concerned (embedded) can just compile those statically
in eina.
Since at the end any real application would use most of modules, we
actually end saving lots of function calls that would do nothing other
than increment a global counter.
I also did the init/shutdown use an array, making it easier to
maintain. The inital dependencies were analysed by a script I wrote, I
hope it's all right.
Please fix any breakages you find!

Note : currently, because of a circular calls of
eina_log_init() and eina_safety_checks_init(), eina
is not correctly shut down. Imho, eina_log should not
depend on the safety checks module. That would mean
some fprintf in eina_log_domain_new(), eina_log_domain_free(),
eina_log_domain_register()and eina_log_domain_unregister().

write down specialized cases for threads or not, function or file,
color or not. Maybe it's not even an optimization since we add yet
another indirection/function call, but each case is simpler.
* EINA_LOG_FILE_DISABLE=1: disables show of file:line in
stderr/stdout messages.
* EINA_LOG_FUNCTION_DISABLE=1: disables show of function() in
stderr/stdout messages.
one must not use the two options at the same time, if that's the case
code will ignore EINA_LOG_FILE_DISABLE=1 and use just function
disable.

Sparse Matrix was implemented and tested by Rafael Antognolli and
myself in order to implement optimized large sparse matrix walk in
some products, one of them WebKit-EFL optimizations.
We have done extensive tests, with good code coverage. Similar to
lists/inlists, we keep pointer to last known element and similar to
iterators we keep reference to last accessed row and cell inside
rows. This allows fast sequential access (for i... for j... m[i,j]),
that is our most common usage case.
Rows are kept in a list, with cells inside that row as another
list. It's not similar to most book implementations where cells keep
reference to their sibling cells in other rows as well, we opted to
not do that to save some pointers and make algorithms simpler, still
do great for our use case.
This code was developed on behalf of our client, that wants to remain
unnamed so far. Thanks client ;-)

note that one can turn per module debug, for example:
EINA_LOG_LEVEL=4 EINA_LOG_LEVELS=eina_stringshare:0 ./bla
will enable level 4 (debug) for all modules except eina_stringshare
that is forced to 0 (just critical messages).
SVN revision: 42224
All these individual init functions are getting messy, some modules
lack them and it's easy to get inconsistent. Safety check needs error
and log, but these need safety checks as well, some modules (lalloc,
rbtree and others) use safety checks but provide no _init().
I want to know if we really gain something to init individual
modules. It should not be that expensive as init should not allocate
heavy resources and the recommendation is to call eina_init() so most
users will do that anyway.
If people agree I'll unmark all *_init() as EAPI and make them private
to eina lib.

Automatically add \n to messages. Since we use that prefix, there is
no use to allow messages without \n, it would look a mess.
Some logging systems may not require the trailing newline, for example
logging to xml or syslog, for those you don't need to ignore this char
if present.
Yes, this breaks convention, but better now than latter. And the
results are not so bad.

EINA_SAFETY_CHECKS will call eina_log, so calling these from inside
eina_log_print() may lead to recursion, that is really bad (although
it seems it would never lead to infinite recursion).

SVN revision: 42198
* stderr logger was doing prefix properly but user message to stdout, fixed.
* log is improved:
* grep-able, it shows the 3 letter level name as prefix, unknown levels
will have their number printed.
* colors just on prefix, less polluted output still easy to spot.
* function names are highlighted.
SVN revision: 42197
* more docs.
* do not getenv("EINA_LOG_ABORT") everytime, just at init.
* EINA_UNLIKELY() in some critical paths (not that big impact anyway)
* eina_log_print_cb_stderr() and use it by default.
SVN revision: 42196
* eina_error might be kept for error messages and codes, but it's logging API
will be deprecated. For now, it's been kept for not breaking others code and
for a smoother transition.
* Added test for new logging API, also demonstrates usage.

eina_list_search_sorted_near_list() was broken and barfed at my face
during development of eina_list_sorted_insert(), so I rewrote it
following more traditional approach, also adding special cases for
head/tail remembering that random access in lists is not as fast as
array. I also simplified that code.
eina_list_sorted_insert() should be fast, O(log2 n) insert, with
special cases to insert already sorted arrays forwards or backwards,
however I believe that it's better to simply append/prepend in those
cases (if known).
SVN revision: 41625
This should not impact anybody, at least in SVN I got no hits for this
function.
The new parameter contains the result of the last call to func(), so
we can know if the node is smaller, bigger or exactly the requested
value and don't need to call func() on node to know for sure.

eina_list_merge() now fixes the smallest list segment, not always the
right. Before if we joined a list 1 to 1000 segments we'd fix all the
1000 instead of the single at left.
Tests to make sure both code paths are being executed.

eina_counter_add -> eina_counter_new
eina_counter_delete -> eina_counter_free
eina_lalloc_delete -> eina_lalloc_free
eina_mempool_new -> eina_mempool_add
eina_mempool_delete -> eina_mempool_del
eina_mempool_alloc -> eina_mempool_malloc
eina_tiler_del -> eina_tiler_free
It remains some questions: have the following API a good name:
eina_module_list_delete
eina_list_free
eina_rbtree_delete

EINA_ITERATOR_FOREACH() and EINA_ACCESSOR_FOREACH() are new macros to
help us forget about nasty C details (like cast to (void **)).
Document most iterators and accessors.
All iterators now set EINA_ERROR_OUT_OF_MEMORY if it's the case.

safety checks will report null pointers and other error conditions on
public api's and can be disabled by compile time check.
note that in order to have these checks working we need to make
EINA_ARG_NONNULL() void, otherwise GCC can remove these checks since
they're known to be false.
This commit also make two minor changes:
* list and hash accessors and iterators are created even for empty
entities. This is correct in my point of view since NULL should
indicate error. Having these in were an optimziation, but not
worth it, these are not the most common case and hitting this path
is not of much cost.
* unmarked some parameters as nonnull, mainly on list and inlist.
SVN revision: 38327
this should help with optimizations and code correctness, please see
"info gcc" for detailed explanation on these.
if you experience some functions not working as expected, please
double check if they're not marked with EINA_PURE or EINA_CONST, maybe
I misused them. Remove the macro and try again.
brief explanation:
* EINA_WARN_UNUSED_RESULT: if you forgot to use the return of some
function, it will emit a warning (and -Werror will make it an
error). This way it will be harder to miss the attribution
"l = eina_list_append(l, v)".
* EINA_ARG_NONNULL(index, index...): if you give it an explicit NULL
argument, or some tool (ie: clang) finds it could get a NULL but
this is not accepted by API, then a warning will be emitted. This
will help those that still use eina_hash_add() as if it is
evas_hash_add().
* EINA_MALLOC: any non-NULL pointer it returns cannot alias any other
pointer valid when function returns.
* EINA_PURE: function have no effects other than the return and this
return just depend on parameters and/or globals. You might call
this function in a loop a thousand times and it will return the
same value, thus you may move this function outside the loop and
remove it.
* EINA_CONST: stricter version of EINA_PURE, it will not check for
global parameters, that is, you cannot consider pointer
arguments. Use it for math things like "int sqrt(int)".
* EINA_PRINTF(fmt, arg): will check format parameter specified in
position "fmt" and passed arguments starting at position "arg", it
will check for things like giving integers where short or strings
were expected.
* EINA_SCANF(fmt, arg): similar to eina_printf().
* EINA_FORMAT(fmt): for use with things like dgettext(), it will get
a printf-like format string and modifies it.
Please review and test it with your software, make sure you make clean
before you install the new version so it has any effect.
If you find some functions are missing EINA_WARN_UNUSED_RESULT and
EINA_ARG_NONNULL or others, please add them.
SVN revision: 38323
give the possibility to write small code like :
it = eina_hash_iterator_tuple_new(hash);
eina_iterator_foreach(it, do_something_cb, NULL);
eina_iterator_free(it);
If hash is empty, but valid it will return a NULL iterator for this
example.
SVN revision: 38104
* evas: if we automatically destroy hash, check for NULL before
handling it to eina api, which expect elements to be created with
eina_hash_new() and thus will fail on NULL.
* eina: add magic checking for eina_hash and eina_hash_iterator, this will
help spot when NULL is used.
* eina_hash_foreach: do not try to create the iterator if hash is NULL.
SVN revision: 37982
By using simpler functions for hash element deletion we can avoid the
hack to shut up GCC warking about hash_num not being used. As these
simple functions are more often needed than the catch-all, expose them
as well.
SVN revision: 37962
Keep EINA_MAGIC at the end of the structure (WHEN POSSIBLE! Watch out
flexible arrays like char str[] at the end!)
this way if parts use EINA_MAGIC and others do not, it will possible overflow and valgrind can help us.
WARNING: make uninstall before update! Then make clean and make install, check if everything is working with "make check".
SVN revision: 37961
eina_magic.h MUST include eina_config.h, otherwise it will not
consider EINA_MAGIC stuff. Worse than that, some files were including
that directly and were considering EINA_MAGIC attribute even if the
file that alloc'ed the memory were not!
Also add missing EINA_MAGIC_SET() to iterators and accessors.
SVN revision: 37960
Many places in EFL we just create walk something, create a list with
walked data, return, then the user walks it again and then deletes
(which will walk again). For such cases it's way better to define
iterators or accessors.
I'm not moving any EFL code to it now, but if people are interested,
things like evas_render_method_list(), evas_font_available_list(),
evas_objects_at_xy_get(), evas_objects_in_rectangle_get(),
evas_object_smart_members_get() are good candidates. If the subject is
already using Eina list, then you can just use
eina_list_iterator_new() and return it, otherwise you can define your
own iterator, which is very easy.
SVN revision: 37956
This is a faster "add", if we know we're using a shared string we know
the node without any need to search it, just increment reference and
exit.
SVN revision: 37458
sizeof(Eina_Stringshare_Node) is now 24 bytes on 64bits platforms, but
str[] was pointing to before that, to the 20th byte, causing out of
bounds access.
Adding the padding will cause str[] to use the correct position. It
wastes 4 more bytes, like pre-optimizations, but it's just on big
machines.
SVN revision: 37305
mixing #ifdef'ed blocks inside code is bad, can lead to warnings if
some variables are not used and it's a pain to read.
instead, just define functions and always call them, choose their
implementation based on the ifdef macros. I opted to have 2
declarations, but one can go like other parts and #ifdef around the
function contents as well.
SVN revision: 37281
we don't need to use 'begin' flag (that takes a byte) just to see if
we're in the same memory block as the head, just do a pointer math.
SVN revision: 37270
trade off safety by speed, we will always assume str was previously
shared, like evas_stringshare_del() did and we can know with zero-cost
the number of references and can avoid strlen() too.
When references drop to zero we still have to do the hash, access the
bucket and then lookup the Red-Black tree, then walk the list of
nodes, but avoiding so would use more memory, unacceptable at this
point.
