Hi,
Today compiling efl with clang some warnings shows. While there are
some false alarms with EINA_INLINE macros (I'll try to check what to
do about those), some are valid.
== eet_chipher.c eet_decipher() ==
lib/eet/eet_cipher.c:1096:8: warning: variable 'opened' is used uninitialized
whenever 'if' condition is true [-Wsometimes-uninitialized]
if (!ret)

lib/eet/eet_cipher.c:1092:8: warning: variable 'opened' is used uninitialized

lib/eet/eet_cipher.c:1130:4: note: variable 'opened' is declared here
int opened = 0;
^
2 warnings generated.
this file is a horror story of using 2 systems. It's leaking the ssl
and gnutls stuff with the goto on_error. The first 'if (!ret) goto
error' happens BEFORE opened was declared... but goto uses that.
Who wrote this file please rewrite this bit using 2 different
functions, one for gnutls and another for openssl, handle memory and
errors right. Then call them from eet_decipher().
== evas_image_load_psd.c ==
bin/evas/loaders/psd/evas_image_load_psd.c:374:70: warning: expression result
unused [-Wunused-value]
for (x = 0; x < (unsigned int)bps2; x += bpp, shortptr)
^~~~~~~~
1 warning generated.
shortptr is in the for(), but not being changed. Later on in the code it does:
newval = *shortptr * ((unsigned
short*)data)[y + x + 3];
using the same ptr. Likely shortptr needs to be incremented, but who
wrote this code please check.
This error is also present in modules/evas/loaders/psd/evas_image_load_psd.c
== dns.c ==
horror story, warnings everywhere, with gcc, clang... can't we have a
sane dns implementation? I know we got this from someone else, but
what's the difficulty in doing it with our tech?
== ecore_x_randr_12.c ==
lib/ecore_x/xlib/ecore_x_randr_12.c:1204:30: warning: comparison of constant
4294967295 with expression of type 'Ecore_X_Randr_Orientation' (aka 'enum
_Ecore_X_Randr_Orientation') is always false
[-Wtautological-constant-out-of-range-compare]
if (orientation == Ecore_X_Randr_Unset)
unset is -1, while orientation is an enum without that value. Some
compilers will just remove this check, as the value can't exist.
Either convert orientation to 'int' (be warned of ABI break), or add
Ecore_X_Randr_Unset to enum (also should break ABI).
== edje_entry.c ==
lots of conversion that are suspicious. We need to check if the enums
match perfectly:
lib/edje/edje_entry.c:2921:62: warning: implicit conversion from enumeration
type 'Edje_Text_Autocapital_Type' (aka 'enum _Edje_Text_Autocapital_Type')

== edje_load.c ==
Similar to edje_entry.c, need to check if the enums match.
lib/edje/edje_load.c:1773:53: warning: implicit conversion from enumeration type
'Edje_Aspect_Control' (aka 'enum _Edje_Aspect_Control') to different

== eeze_scanner.c ==
Abuse of some variables? I don't get the logic in there, clang doesn't as well:
bin/eeze/eeze_scanner.c:298:43: warning: implicit conversion from enumeration
type 'Eeze_Scanner_Event_Type' to different enumeration type
'Eeze_Udev_Event' [-Wenum-conversion]

Would be nice if someone could check those.
