eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:
```sh

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:
```sh
$ export EO_LIFECYCLE_NO_DEBUG=Efl_Loop_Timer,Efl_Promise,Efl_Future

eo: rework vtable allocation scheme
Summary:
with this commit a new way of allocating vtables arrived.
The old mechnism was to allocate a table big enough to carry *all*
functions at once, in order to not allocate that much memory for
functions that are not implemented on a specific klass, dichchains have
been used, which can be seens as a 2D matrix, where columns are only
allocated if min 1 entry needs to be written, this may have been a good
way to allocate back in the day when all this with eo started, however,
it showed to not pay off.
With this new way, we allocate a array of arrays. the first lvl array is
carrying enough slots, that *all* up to the time defined
interfaces/classes/abstracts/mixins can be implemented. The second lvl
array then has exactly the size of the defined APIs. The second lvl
array is obviously only allocated if needed.
When comparing the two methods, i messured two things, the usage based
on memory allocation for vtable-way-1 and vtable-way-2. Additionally, i
checked the overall memory usage of elementary_test using pmap. The
first messurement is a little bit more exact. The second messurement is
more biased, but captures the whole picture.
Memory allocation tracking:
vtable-way-1 - vtable-way-2 = 74680 Byte
Pmap memory tracking:
vtable-way1 - vtable-way-2 = 217088 Byte
The second messurement shows a bigger impact, likely because this is
also showing off all the sideeffects that we are taking place due to
fewer allocations.
Depends on D11524

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

Fixes a constant memory leak.
eina: introduce EINA_HOT and EINA_COLD
These attributes respectivelly expand to __attribute__ ((hot)) and

eo: speed-up generated calls by removing call cache
The call cache needed to by thread-local, to avoid concurrency issues.
Problem with TLS is that is adds an extra overhead, which appears to be
greater than the optimization the cache provides.
Op is naturally atomic, because it is an unsigned integer. As such, it
cannot be tempered with while another thread is reading it. When
entering the generated function, the first operation done is reading
'op'. If we have concurrency, we will have access sequences returning
either EFL_NOOP or a VALID op, because 'op' is not set until the very
end of the function, when everything has been computed. As such, we now
use the 'op' atomic integer to instore a lock-free/wait-free mechanism,
which allows to drop the TLS nature of the cache, speeding up the access
to the cache, and therefore making functions execute faster.
We don't test anymore the generation count. This can be put as a
limitation. If means that if you call efl_object_shutdown() and
re-initialize it later with different data, opcodes will be invalid.
I am not sure there is any usecase for this to ever happen.
We could move all the caches in a dedicated section, that can be
overwritten after a call to efl_object_shutdown(), but I am not sure it
will be very portable.

use the 'op' atomic integer to instore a lock-free/wait-free mechanism,
which allows to drop the TLS nature of the cache, speeding up the access

We don't test anymore the generation count. This can be put as a
limitation. If means that if you call efl_object_shutdown() and
re-initialize it later with different data, opcodes will be invalid.
I am not sure there is any usecase for this to ever happen.
We could move all the caches in a dedicated section, that can be
overwritten after a call to efl_object_shutdown(), but I am not sure it
will be very portable.

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why

eo: Rename EAPI macro to EO_API in Eo library
Summary:

This patch is from a series of patches to rename EAPI symbols to

EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used

MSVC __almost__ works like GCC (or mingw) in which you can

For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: rework vtable allocation scheme
Summary:
with this commit a new way of allocating vtables arrived.
The old mechnism was to allocate a table big enough to carry *all*
functions at once, in order to not allocate that much memory for
functions that are not implemented on a specific klass, dichchains have
been used, which can be seens as a 2D matrix, where columns are only
allocated if min 1 entry needs to be written, this may have been a good
way to allocate back in the day when all this with eo started, however,
it showed to not pay off.
With this new way, we allocate a array of arrays. the first lvl array is
carrying enough slots, that *all* up to the time defined
interfaces/classes/abstracts/mixins can be implemented. The second lvl
array then has exactly the size of the defined APIs. The second lvl
array is obviously only allocated if needed.
When comparing the two methods, i messured two things, the usage based
on memory allocation for vtable-way-1 and vtable-way-2. Additionally, i
checked the overall memory usage of elementary_test using pmap. The
first messurement is a little bit more exact. The second messurement is
more biased, but captures the whole picture.
Memory allocation tracking:
vtable-way-1 - vtable-way-2 = 74680 Byte
Pmap memory tracking:
vtable-way1 - vtable-way-2 = 217088 Byte
The second messurement shows a bigger impact, likely because this is
also showing off all the sideeffects that we are taking place due to
fewer allocations.
Depends on D11524

Summary:

This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with

With current EAPI definitions, we get the following example

This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

efl_class_functions_set ( const Efl_Class * klass_id , const Efl_Object_Ops * object_ops , const Efl_Object_Property_Reflection_Ops * reflection_table )
Efl object: change the way we set class's functions.
This is another follow up to the investigations of T4227. As stated
there, in any PIE (a shared library is one), structures, even const ones
end up being written to because of dynamic relocation. This means that
using static const structures has actually lead to no savings, only
waste. Since we never really needed them, using them made things even
worse than just having a different API that doesn't save them.
Thus, this commit changes the way we set the functions. Instead of
passing a pre-populated struct, we now just have an initialiser function
where you set the functions. This on its own doesn't significantly reduce
the amount of dirty memory pages for a reason I have yet to uncover,
though I believe it's done as a misguided compiler optimisation.
However, this design is flexible enough so we can change to another one
that is quite ugly, but I have already tested and proven that does that.
This patch series doesn't include the better improvement (passing
everything on the stack as va_args) because the API was too ugly
for me to bear, and I would rather first make sure there is no way to
force the compiler to do the right thing here.
Unfortunately this commit gives up on useless stricter validation.
Before this commit we would make sure that we are only overriding
functions correctly defined in our hierarchy. With this one, we don't
anymore. This is not a big problem though because this is a check that
is also enforced by Eolian. So as long as you are using Eolian, you
should be fine.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on

Efl object: change the way we set class's functions.
This is another follow up to the investigations of T4227. As stated
there, in any PIE (a shared library is one), structures, even const ones
end up being written to because of dynamic relocation. This means that
using static const structures has actually lead to no savings, only
waste. Since we never really needed them, using them made things even
worse than just having a different API that doesn't save them.
Thus, this commit changes the way we set the functions. Instead of
passing a pre-populated struct, we now just have an initialiser function
where you set the functions. This on its own doesn't significantly reduce
the amount of dirty memory pages for a reason I have yet to uncover,
though I believe it's done as a misguided compiler optimisation.
However, this design is flexible enough so we can change to another one
that is quite ugly, but I have already tested and proven that does that.
This patch series doesn't include the better improvement (passing
everything on the stack as va_args) because the API was too ugly
for me to bear, and I would rather first make sure there is no way to
force the compiler to do the right thing here.
Unfortunately this commit gives up on useless stricter validation.
Before this commit we would make sure that we are only overriding
functions correctly defined in our hierarchy. With this one, we don't
anymore. This is not a big problem though because this is a check that
is also enforced by Eolian. So as long as you are using Eolian, you
should be fine.
Breaks API and ABI!

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

Eo: Remove GCCism and make it more portable.
This affects eo_do() and eo_add() that used to use the ({}) GCCism.
Following a discussion with Peter de Ridder after my talk at FOSDEM,
we've decided to reopen the GCCism (works with other gcc compatible
compilers like clang and intelc) discussion, and after a bit of back and
forth it was decided to make things more portable, at the cost of ease
of use.
For example:
if (eo_do(obj, visible_get()))
is no longer allowed, the portable alternative
Eina_Bool tmp;
if (eo_do_ret(obj, tmp, visible_get()))
is to be used instead.
However:
eo_do(obj, a = a_get(), b = b_get(), bool_set(!bool_get))
are still allowed and OK.
eo_do(obj, if (a_get()) return;);
is no longer allowed, but:
eo_do(obj, if (a_get()) something());
is still allowed.
For clarity, this commit only incorporates the Eo changes, and not the
EFL changes to make the efl conform with this change.
Thanks again to Peter de Ridder for triggering this important discussion
which led to this change.

Eo: Remove GCCism and make it more portable.
This affects eo_do() and eo_add() that used to use the ({}) GCCism.
Following a discussion with Peter de Ridder after my talk at FOSDEM,
we've decided to reopen the GCCism (works with other gcc compatible
compilers like clang and intelc) discussion, and after a bit of back and
forth it was decided to make things more portable, at the cost of ease
of use.
For example:
if (eo_do(obj, visible_get()))
is no longer allowed, the portable alternative
Eina_Bool tmp;
if (eo_do_ret(obj, tmp, visible_get()))
is to be used instead.
However:
eo_do(obj, a = a_get(), b = b_get(), bool_set(!bool_get))
are still allowed and OK.
eo_do(obj, if (a_get()) return;);
is no longer allowed, but:
eo_do(obj, if (a_get()) something());
is still allowed.
For clarity, this commit only incorporates the Eo changes, and not the
EFL changes to make the efl conform with this change.
Thanks again to Peter de Ridder for triggering this important discussion
which led to this change.

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:
```sh

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:
```sh

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

Efl object: change the way we set class's functions.
This is another follow up to the investigations of T4227. As stated
there, in any PIE (a shared library is one), structures, even const ones
end up being written to because of dynamic relocation. This means that
using static const structures has actually lead to no savings, only
waste. Since we never really needed them, using them made things even
worse than just having a different API that doesn't save them.
Thus, this commit changes the way we set the functions. Instead of
passing a pre-populated struct, we now just have an initialiser function
where you set the functions. This on its own doesn't significantly reduce
the amount of dirty memory pages for a reason I have yet to uncover,
though I believe it's done as a misguided compiler optimisation.
However, this design is flexible enough so we can change to another one
that is quite ugly, but I have already tested and proven that does that.
This patch series doesn't include the better improvement (passing
everything on the stack as va_args) because the API was too ugly
for me to bear, and I would rather first make sure there is no way to
force the compiler to do the right thing here.
Unfortunately this commit gives up on useless stricter validation.
Before this commit we would make sure that we are only overriding
functions correctly defined in our hierarchy. With this one, we don't
anymore. This is not a big problem though because this is a check that
is also enforced by Eolian. So as long as you are using Eolian, you
should be fine.
Breaks API and ABI!

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

Efl object: change the way we set class's functions.
This is another follow up to the investigations of T4227. As stated
there, in any PIE (a shared library is one), structures, even const ones
end up being written to because of dynamic relocation. This means that
using static const structures has actually lead to no savings, only
waste. Since we never really needed them, using them made things even
worse than just having a different API that doesn't save them.
Thus, this commit changes the way we set the functions. Instead of
passing a pre-populated struct, we now just have an initialiser function
where you set the functions. This on its own doesn't significantly reduce
the amount of dirty memory pages for a reason I have yet to uncover,
though I believe it's done as a misguided compiler optimisation.
However, this design is flexible enough so we can change to another one
that is quite ugly, but I have already tested and proven that does that.
This patch series doesn't include the better improvement (passing
everything on the stack as va_args) because the API was too ugly
for me to bear, and I would rather first make sure there is no way to
force the compiler to do the right thing here.
Unfortunately this commit gives up on useless stricter validation.
Before this commit we would make sure that we are only overriding
functions correctly defined in our hierarchy. With this one, we don't
anymore. This is not a big problem though because this is a check that
is also enforced by Eolian. So as long as you are using Eolian, you
should be fine.
Breaks API and ABI!

Efl object: change the way we set class's functions.
This is another follow up to the investigations of T4227. As stated
there, in any PIE (a shared library is one), structures, even const ones
end up being written to because of dynamic relocation. This means that
using static const structures has actually lead to no savings, only
waste. Since we never really needed them, using them made things even
worse than just having a different API that doesn't save them.
Thus, this commit changes the way we set the functions. Instead of
passing a pre-populated struct, we now just have an initialiser function
where you set the functions. This on its own doesn't significantly reduce
the amount of dirty memory pages for a reason I have yet to uncover,
though I believe it's done as a misguided compiler optimisation.
However, this design is flexible enough so we can change to another one
that is quite ugly, but I have already tested and proven that does that.
This patch series doesn't include the better improvement (passing
everything on the stack as va_args) because the API was too ugly
for me to bear, and I would rather first make sure there is no way to
force the compiler to do the right thing here.
Unfortunately this commit gives up on useless stricter validation.
Before this commit we would make sure that we are only overriding
functions correctly defined in our hierarchy. With this one, we don't
anymore. This is not a big problem though because this is a check that
is also enforced by Eolian. So as long as you are using Eolian, you
should be fine.

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.

When appending __attribute__((const)) to a function, the compiler is

This is quite often happening when we are efl_data_scope_get and
efl_super in a function that is different from a implemented function.
The compiler now starts to remove the calls that aggressivly that we
need to ensure that these calls are not removed, which means, the static

Please note that you now have to be carefull when your app calls
eo_shutdown, if it does so, you *must* call it at the end of a function,
or never call class_get after that anymore.
Overall this improves elm test runs 0.1s which is fair i guess, the main
thing that is faster is textrendering, where is also the point where
this is the most beneficial.
Please note, this replaces 42 occurences of double _class_get() ... THAT

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.

foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()

}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and

compiled with EO_DEBUG, thus shouldn't cause any performance hits on

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:
```sh

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:
```sh

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:
```sh

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.
Running a bogus app with invalid efl_class_name_get() and double
efl_del() will report as below:

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on

eo: allow valgrind-like tracking of object lifecycle.
Eo pointer indirection is super nice as it avoids you to access
invalid memory, but this extra checks inhibits valgrind's own tracking
of memory lifecycle, usually it would report when the object was
created and when the object is deleted, both as stack traces.
This commits introduces logging of object creation and destruction
under its own eina_log_domain and controlled by EO_LIFECYCLE_DEBUG and
EO_LIFECYCLE_NO_DEBUG envvars. These will only be available if
compiled with EO_DEBUG, thus shouldn't cause any performance hits on
production code.

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

eo: Rename EAPI macro to EO_API in Eo library
Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example

{
