Hi all,
I noticed during current builgs, on Ubuntu 16.10 (Yakkety) and now also on
Debian 9 (Stretch) was changed the default compiler to GCC6. This brings
the number of new FTBFS. That's why I started to concentrate on these
FTBFS. Note - for this reason the packages for Yakkety in Preliminary
Stable Builds are now inconsistent.
As a first, of course, I started with tdelibs. Most were simple conflict
signed / unsigned char or int. However, one serious problem is here.
In the 'kjs' and 'tdehtml/ecma' is used HashEntry structure that contains
the item 'value' of type short int - see 'kjs/lookup.h'. Into this item
was stored values DOM::NodeFilter::ShowCode::SHOW_ALL = 0xFFFFFFFF (see
tdehtml/dom/dom2_traversal.h) and kjs event CHANGE with value 32768 (see
tdehtml/ecma/kjs_events.cpp). Both are therefore outside the range of
short int.
Changing the type of 'value' in HashEntry from short to long would
apparently cause a change in ABI - kjs/lookup.h is part of the public
includes. That's why I made the change values 0xFFFFFFFF and 32768 to -1.
I think that GCC compilers version less than 6 will store these values in
the same way. Therefore, I believe that the proposed patch would not
cause problems == can be pushed. What is your opinion?
Cheers
