This commit changes the way refcount is dealt with internally. Before
this commit, there was one refcount shared between Eo internals and
users. Now there is a refcount for eo operations (like for example,
function calls) and one for user refcount (eo_ref).
An example bug that this protects against (which is seemingly rather
common) is:
some_eo_func(obj);
// Inside the implementation of that func:
pd->a = 1; // The object's private data
eo_unref(obj); // To delete the object
eo_unref(obj); // A big one extra unref
pd->a = 2; // Segfault, this data has already been freed
This is a feature, but really just a fix for a class of bugs.

The trivial case of [pos,pos] (i.e. range of length 0) didn't work if there is a
format item in 'pos'.
The condition was fixed to not include such items. The reason it was not
apparent for text items is that these have further handling in the rest of the
code and would've been disposed of.
@fix
Summary:
Font size is scaled according to scale factor.
The linesize, linegap formats also have to be scaled properly.

so after some discussion with jpeg, weak referenced keys are also a
good idea. these need del track handling to be weak, so i made strong
reffed keys also do del tracking again as it's just nice to do this
and be more robust. also added and improved the test suites for this
key value stuff.

This test is stalling. Locally as well as on Jenkins. I tried to bisect it
without any luck. Even running it from the 1.17 release it does no longer work
so i guess it is some change coming from a pulse update on my system. I have
version 7.1 here. As we have no-one working actively on ecore_audio I disable
the test here and we can track the problem on T4018.
Adds two new type types, STATIC_ARRAY and TERMINATED_ARRAY. Static arrays are
only allowed as struct members right now - they translate to regular C static
arrays (allowing them elsewhere wouldn't be good, as C isn't very good at
working with the size information). Terminated arrays are basically sequences
of data terminated at the end. The base type of static arrays can be any type
that is not marked ref (explicit ref may get allowed later). The base type of
terminated arrays has the same restriction plus that it has to be either
implicitly reference type (i.e. translating to pointer in C), integer type
or a character. In case of ref types, the terminator is NULL. In case of
integer types, the terminator is a zero. In case of character types, the
terminator is also a zero (null terminator like C strings).

Not really somethign we would hit here but still better to change this.

Instead of being a key "audio_mute" + another key "channel"
I've simply implemented a number of different keys:
audio_mute (= all)
audio_mute_all
audio_mute_effect
...
This is to port elm_config to EO APIs.
The current implementation relies on the legacy API, by
simply forwarding calls.
The new API is simply efl_config_set("config_name", value)
where value is an Eina_Value (aka. generic_value).
The C interface proposes a few helpers like config_int_set,
config_double_set, etc...
Unfortunately at the moment, not all config options are
supported, as some rely on more complex types:
- lists
- color class and multiple arguments
- unset functions
- enums
Profiles are also not handled at this point.
@feature
This implements a new builtin, stringshare, which is replaced with the right
pointer to Eina_Strinshare as necessary. This allows simplifying binding code
(it can call the proper eina APIs, deal with lifetime etc).
It also removes the extern Eina.Stringshare typedef from eina_types.eot, which
was actually incorrect and would generate invalid code in binding generators.
@feature @fix
This was discussed and still wasn't decided whether this is required to be
supported internally.
The reason for this revert is that the behavior still needs tweaking to work
just right along with the legacy behavior.
Evas.Common_Interface not only had a bad name, it also
wasn't in line with how we can get a loop object, for
instance.
Use eo_provider_find in each implementing class.
This was needed when the eo composite object was still in beta. Since commit
d7c45e41d4 this is no longer the case. No beta
part left in eo base so we can safely remove this define.
The implementation depends on creating different code paths from the now-legacy
behavior of text appending.
The annotation system introduced in this commit replaces the current way of
applying formats on text.
Up until now it has been quite a hassle for the user to control the formats, as
it required keeping track of the format positions with an opener and closer
formats almost every time (with the exception of own-closing formats).
The combination of Efl.Text API along with the Efl.Canvas.Text annotation API
essentially replaces the capabilities of the old format.
There is additional annotation API to allow more control, so be sure to check
the documentation/.eo files and the wiki page of Efl.Canvas.Text.
The style API now accepts actual strings of format style. There is not longer
need to instantiate as style with style_new() followed later by style_free().
@feature
evas canvas will be removed from eo.
evas_output_XXX APIs are usually used by widget or e17.
I decided not open these kind of APIs to eo.
app can use the size of elm win instead of evas output apis.
Inner type can now be retrieved as a base type of the type.
If the type has two inner types or more, there is a new API that allows you to
get the second inner type by calling it on the first one (same would apply to
getting third via second etc.).
This API is simpler to use and doesn't require an iterator.
It's now possible to mark struct fields and function params as "references",
which causes them to become pointers in C (in bindings, they become whatever
is necessary). They're not a part of the type and are much more restricted
than pointers, allowing bindings to be easier. This system will be gradually
utilized and expanded as required.
@feature
We set it but never going to use it afterwards. We already tests the
efl_gfx_buffer_colorspace_get() elsewhere in this tests so we can ignore it
for now until we need it and bring it back together with a user.
Cancelling a promise will fulfill it but won't actually free the memory. This
memory is under custody of the owner, who must either call value_set or
error_set to finish it.
When compositing objects, we were checking that class_of(B) is in A's
inheritance tree before allowing attaching B as a composite object of A.
This is wrong and breaks a few cases, for example: B extends a class that
is in A's inheritance tree or B implements an interface that is in A's
inheritance tree.
Thanks to Marcel for reporting.
Now when dealing with pointer types, we will not get pointer to
pointer semantics in callbacks and eina_promise_owner_value_set
for Eina_Promise.
It will work as expected:
Eina_Promise_Owner* promise = eina_promise_add();
void* p = malloc(sizeof(T));
eina_promise_owner_value_set(promise, p, &free);
This lets me narrow down the remaining cases of pointers across the EFL.
The void pointers will later need to be reevaluated on per-case basis and
replaced appropriately where possible/feasible.
This reverts commit 546ff7bbba.
It seems that eo_del() is useful and removing it was creating bugs.
The issue is that the way we defined parents in eo, both the parent and
the programmer share a reference to the object. When we eo_unref() that
reference as the programmer, eo has no way to know it's this specific
reference we are freeing, and not a general one, so in some
circumstances, for example:
eo_ref(child);
eo_unref(child); // trying to delete here
eo_unref(container); // container is deleted here
eo_unref(child); // child already has 0 refs before this point.
We would have an issue with references and objects being freed too soon
and in general, issue with the references.
Having eo_del() solves that, because this one explicitly unparents if
there is a parent, meaning the reference ownership is explicitly taken
by the programmer.
eo_del() is essentially a convenience function around "check if has
parent, and if so unparent, otherwise, unref". Which should be used when
you want to delete an object although it has a parent, and is equivalent
to eo_unref() when it doesn't have one.
Test wasn't enabled when modifications to function prototypes to
eio_job_file_xattr_list and eio_job_file_xattr properties were
made, so it got pushed inadvertidly without the necessary
changes to user code.
This touches Edje and also Elementary where part names are used.
This commit blew up in size since now all content part APIs
(get, set, unset) require to use Efl.Part instead.
This is a big refactoring commit, but no logic should
have been changed. Fingers crossed.
accidentally snukc in commented disables in test suite as i was
hunting why eina test suite crashes while dealing with feedback on my
compare fixes etc.
The legacy Eio_File factory functions are replaced by an Eo object
called Eo_Job that return promises wrapping the async file operations.
With this commit, the legacy Eio callbacks are replaced by the following
Eo/Promises counterparts :
* Done_Cb -> Promise then success callback
* Error_Cb -> Promise then error callback
* Main_Cb -> Promise progress callback
* Filter_Cb -> Job object event (more below)
Events are used to deliver and get the filter data. To differentiate
between the named and direct versions, they come in "filter,direct" and
"filter,name" versions.
Monitors were wrapped inside a new class Eo_Sentry.
The user creates a sentry object and adds monitoring targets to it,
listening to events on it.
The sentry event info is composed of two strings. The source string
is the path being monitored, i.e. the one passed to eio_sentry_add, and
the trigger string is the path that actually triggered the event, e.g.
a new file created in a monitored directory.
The Eio functions operating on Eina_Files were just freeing
the Eio_File pointer on completion instead of calling eio_file_free
to unregister the thread.
sothe ecore-con tests were calling ecore_con_server_connected_get()
every time a server was created on a NUL server object. WTF? this is
pointless. testing if an api returns tre on being connected on an
invalid object? all it does is create lots of eo noise. remove so we
can see the real errors in the output.
@fix
Complex types (i.e. list, array, hash, accessor etc.) now do not require
pointers with them anymore (the pointer is implied) and the same goes for
class handles. Eolian now explicitly disallows creating pointers to these
as well. This is the first part of the work to remove pointers from Eolian
completely, with the goal of simplifying the DSL (higher level) and therefore
making it easier for bindings (as well as easier API usage).

Apparently you can't cast when initializing static consts, even if
the cast is to the same type. This commit splits the macro used
so we have an additional one that casts and thus works with
eo_override().
This change lets you override the functions of objects so that those
functions will be called instead of the functions of the class. This
lets you change objects on the fly and makes using the delegate pattern
easier (no need to create a class every time anymore).
You can see the newly added tests (in this commit) for usage examples.
@feature
Previously events used to use class name as a prefix and ignored eo_prefix
when specified. This is no longer the case. Events follow eo_prefix by default
now. In order to get around this for classes where this is undesirable, a new
field event_prefix was added which takes priority over eo_prefix. If neither
is specified, class name is used like previously.
@feature
We used to have eo_del() as the mirrored action to eo_add(). No longer,
now you just always eo_unref() to delete an object. This change makes it
so the reference of the parent is shared with the reference the
programmer has. So eo_parent_set(obj, NULL) can free an object, and so
does eo_unref() (even if there is a parent).
This means Eo no longer complains if you have a parent during deletion.
We missed tmpstr_del and shutting down eina here. This test segfaults from
time to time on Jenkins. Not sure this was the actual cause but better clean
it up anyway.

Added eina_promise_race function that composes multiple
promise objects into a new promise which is fulfilled
when one of the promises are fulfilled, or fails
when one of the promises have failed.
The one and only valid use case is calling a function directly on
the part handle, like:
func(part_get(obj, "part"), args).
This does not change the actual proxy object lifecycle or resolve
any potential issues, but this should clear up things in terms
of scope for proper (supported) use.
efl_content_get may become efl_part() and return a temporary object,
valid for a single function call. Those are "details" still to be
refined.
Add a way for users of the promise owner to get notified when a
promise progress is registered. Also added a convenience composition
function that creates a promise which is fulfilled when another
promise has a progress notification.
This commit breaks behaviour!
Re-parenting no longer detaches composite objects, so watch out.
Now you can have an object be a composite object of an object although
it's not its child. This allows widgets to do things like having an
object as the child of a child object while still making it a composite
object to the main object.
With this change, composite objects don't keep a reference to the child,
but instead composite "bonds" are implicitly removed when either the
parent or the child are destructed.
Summary:
object_find is more generic, so other mechanisms can also reuse the
code.
The object itself has to support the function, so there is no need for
eo_isa which would have a negative performance impact.
The base class implementation calls interface_get on the parent, so a
override of the function can just call the super function to continue in
the recursion.
Test Plan: just run the eo test suite
