* eo: move event related structures and callback to CDaniel Kolesa2017-04-212-28/+30
| | | | | | We don't need to keep this in eo files anymore because the APIs using them are now fully in C. This also allows removal of the event callback builtin from Eolian.
* eo: move unbindable event APIs to CDaniel Kolesa2017-04-203-78/+123
| | | | | | | | | In a few classes, this requires some manual expansion. This should not break anything but it's also fairly ugly; a better solution would be appreciated, for now we do this. Similar changes will be done to a few other Efl.Object APIs as well at later point.
* eo: move Efl_Event definition back to CDaniel Kolesa2017-04-202-8/+12
| | | | It's not used anywhere in eo files and has a void pointer.
* eo: Micro-optimize function callsJean-Philippe Andre2017-04-191-15/+26
| | | | This is related to the previous changes to efl_super.
* eo: Remove super bit from eo idJean-Philippe Andre2017-04-192-17/+5
| | | | | It is not required anymore as the super class and super bit can be stored inside the object data. See the previous patches.
* eo: Add docs for efl_super and efl_cast (doxygen)Jean-Philippe Andre2017-04-191-0/+70
|
* eo: Add new API efl_castJean-Philippe Andre2017-04-192-7/+24
| | | | | | | | | | | | | | | | | | This is similar to efl_super but the specified class is the one we want to call the function on. This is similar to dynamic_cast<> in C++. Note: both efl_super() and efl_cast() need documentation! This is an experimental feature. Fixes T5311 @feature Maniphest Tasks: T5311 Differential Revision: https://phab.enlightenment.org/D4797
* eo: Remove lock from efl_superJean-Philippe Andre2017-04-192-29/+31
| | | | | | | | | | | | | | | | | I've always really disliked this lock. If someone calls a non-eo function by accident with efl_super() then you'll most likely end up in a deadlock. This adds the cur_klass pointer to the object itself, exploiting the fact that we have 8 bytes of padding (on 64 bits, at least). Also, this opens the door to efl_cast() which would be similar to efl_super() except that only a dynamic cast is done, not a call to the parent function. make benchmark shows a performance improvement, surprisingly. This is a bit experimental. See also the following commit (efl_cast)
* eo: Use COW to save 8~16 bytes per objectJean-Philippe Andre2017-04-183-49/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This uses Eina_Cow to implement support for rarely used features in EO objects. This covers: - composite objects (eg. UI widgets: combobox, text, video, win) - vtable for efl_object_override - del_intercept All of these features are quite tricky to get right and while very useful, should still be used with great care. With this patch, the size of an _Eo_Object struct comes down from 80 bytes (rounded up from 72b) to 64 bytes (rounded up from 56b) on 64 bits. Also I haven't measured precisely but I don't expect any performance impact since the COW data is more likely to remain in L1/L2 cache, as the default one will be used most often. Unfortunately, the results of "make benchmark" have been quite inconsistent over multiple runs. This saves ~64kb in elementary_test (>4k objects) at the cost of ~100 calls to COW write (del intercept on some events). @optimization Reviewers: raster, cedric Differential Revision: https://phab.enlightenment.org/D4796
* eo: Fix crash in case of API misuseJean-Philippe Andre2017-04-181-1/+4
| | | | | | | | | | If efl_object_override() is called with a function that does not exist in the original class, it may lead to a crash on indexing an non-existing array in the vtable. This is really just a safety check, as the usage was wrong: * You are only allowed to override functions that are defined in the * class or any of its interfaces (that is, efl_isa returning true).

* eo: ensure the generation is correctly clampedMarcel Hollerbach2017-02-161-5/+27
| | | | | | | | | | | | | | | | | | | | | | | | Summary: when a few recursive event emissions are happening, and in some deep recursive level a subscription to the same object is happening, the subscription would just be executed when the complete recursion is done. that is wrong. The subscription needs to be executed when the event is called after the subscription is added, undepended from any recursive level. That fixes that and adds a regression test for it. This was discovered in e, since e gives a lot of error messages about a eo object that is already freed. It turned out this object is returned from evas, and exactly the above happened to the EFL_EVENT_DEL subscription of that object.

* eo: Fix shadow variable warningJean-Philippe Andre2017-02-151-1/+1

* eo_debug: Remove some abusive goto where not neededJean-Philippe Andre2017-02-151-15/+13
| | | | | | | goto was used for micro-optimization. There is absolutely no need for those if we're using the slow path with eo_debug. Simplify the code.
* eo_debug: Some more log improvementsJean-Philippe Andre2017-02-151-13/+9
| | | | Nothing fancy here...
* eo_debug: Improve dangling xref debug logs even moreJean-Philippe Andre2017-02-152-29/+65
| | | | | | | | | | In case of manual free, as is heavily used by Evas, we can't really print an ERR if there are still references before free has been called. This may not be ideal from a pure EO point of view but considering how Evas uses manual free this is the best solution to avoid polluting debug logs.
* eo_debug: Improve one logJean-Philippe Andre2017-02-152-1/+13
| | | | | | | | | | | | | | | This changes the following message when the object is referencing its own data. Also lowers from ERR to WRN and adds the class name for the referenced data. ERR<17450>:eo /home/jpeg/e/core/efl/src/lib/eo/eo_private.h:337 _efl_unref_internal() in /home/jpeg/e/core/efl/src/lib/eo/eo.c:620: func '_efl_object_call_end' Data of object 0x400000021008db58 is still referenced by object 0x400000021008db58 Note that evas and elm have a few calls to efl_data_ref(obj, NULL) which are imho quite ugly: not using the return value and not specifying the data class. I'm keeping them as-is for now.

* eo base - fix warnings for debug logs to get format string types happyCarsten Haitzler (Rasterman)2017-02-121-9/+9
| | | | | gcc is very unhappy with these log prints - specifically on arm 32bit. this fixes it so we can focus on real warnings/issues.
* efl base class - fix warning about comparing differing sizesCarsten Haitzler (Rasterman)2017-02-111-1/+2
| | | | | | | yes - we compare a difference between 2 ptrs and an index which is a uint. the safe thing here is to promote the unit to the ptrdiff_t type. reality is we cant have more than 2^32 cb's on an object anyway... so this should be ok.

* eo_debug: print tracebacks for more errors.Gustavo Sverzut Barbieri2016-12-202-0/+4
| | | | | If eo_debug (libeo_dbg/EO_DEBUG), then print tracebacks if lifecycle is being tracked.
* Eo: remove unreachable code in isa.Tom Hacohen2016-12-151-1/+0
| | | | | | | | | This condition can never be true. It can't be NULL here. A NULL here would have caused a crash earlier, though it can only be NULL if an allocation fails, which is something that we don't really handle for smallish allocations. CID1366823
* Efl_Future: class name (string) using "." for namespace.Gustavo Sverzut Barbieri2016-12-121-1/+1
| | | | | Following recent eolian change, the string must have "." to split namespace, not "_".
* eo_lifecycle: on log level info (3), show leaked objects.Gustavo Sverzut Barbieri2016-12-081-0/+36
| | | | | | | Since we keep a log of created and deleted objects, we can walk the log and see which were leaked. As this is expensive, do only if log level is greater than 3 (INFO, DEBUG...), with backtrace of object creation being displayed as backtrace if running as level 4 (DEBUG).
* Eo: Fix efl_isa() sometimes returning wrong results with extensionsTom Hacohen2016-12-071-22/+23
| | | | | | | | | | | | | | | | | | | | This fixes an issue where efl_isa() wouldn't work for extensions or ancestors of extensions of a class. Example: Class A implements interface F2 F2 inherits from interface F1 obj is of class A Before this patch efl_isa(obj, F1) would return false, now it returns true as expected. This is just one example, there is a whole array of variations to this issue that are now fixed. Thanks to Gustavo for reminding me of this. @fix
* eo: guard lifecycle obj log inside spinlock.Gustavo Sverzut Barbieri2016-12-061-1/+12
| | | | | since the array can be pushed or looked up from multiple threads we must have a lock in place.
* eo: guard all efl_super() checks under EO_DEBUG.Gustavo Sverzut Barbieri2016-12-061-2/+2
| | | | | | Tom is worried about performance hit (god, checking a bit in a pointer we'll fetch to memory anyway, since we return it masked), so guard under EO_DEBUG.
* all: use void if we really want to make sure we do not accept parametersStefan Schmidt2016-12-061-1/+1
| | | | | | In C we need this to make clear that we really do not accept parameters. Found by the smatch source code matcher. I had run and fixed this before but it seems to creep in again over time.

* eo: Make error message less nebulousJean-Philippe Andre2016-12-051-1/+2
| | | | | | When writing this ERR log I thought about "thread" (it's really the keyword here) but eventually reworded to "context". Let's be clearer about the possible issue here.
* eo: do not use eina_trash when running on valgrind.Gustavo Sverzut Barbieri2016-12-031-1/+11

* eo: fix build on macOSJean Guyomarc'h2016-12-031-0/+4
| | | | | Commit 227463bd introduces macOS-specific code, but without including the header that provides the used declarations.
* eo: more information when we cannot resolve method.Gustavo Sverzut Barbieri2016-12-022-2/+19
| | | | | | | | | | | | | | | | | | | _efl_object_api_op_id_get() will query a hash for the given pointer, however if it wasn't populated, it will return "NOOP" and we're hopeless while debugging on what happened. Common case is to use the incorrect method, like: obj = efl_add(CLS1, ...); cls2_method(obj); Since we did not create CLS2, it won't populate its methods on the hash, thus the lookup will return NOOP. With this change the function now gets the target object and function name so reports an insightful message such as: ERR:eo file.c:123 cls2_method() Unable to resolve op for api func 0x7ff492ddea00 for obj=0x400000007e8ee1df (CLS1)
* eo: allow valgrind-like tracking of object lifecycle.Gustavo Sverzut Barbieri2016-12-025-50/+614
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | if for some reason we fail to validate a class, then we should skip that extension. This may result in an empty vtable, then check for that and avoid a crash. This is very unlike to happen in practice, but I've forced some validation errors and could get to that.
