I don't think any valid C program can contain `<=>` in a tokenisable
context, but it's more helpful to fail with a syntax error at SWIG
parse time and not potentially generate C code trying to use `<=>` in
an expression which then fails at compile time.
Remove some erroneously added brackets_increment() calls.
Reject <=> in preprocessor expressions with a clear error message (it
seems it isn't supported here - clang and gcc don't at least).
The type returned by `<=>` is not `bool`. We pretend it's
`int` for now, which should work for how it's likely to be used
in constant expressions.
Fixes#1622
Exit() is a wrapper for exit() by default, but SetExitHandler() allows
specifying a function to call instead.
This means that failures within DOH (e.g. Malloc() failing due to lack
of memory) will now perform cleanup such as removing output files.
This commit also cleans up exit statuses so SWIG should now reliably
exit with status 0 if the run was successful and status 1 if there was
an error (or a warning and -Werror was in effect).
Previously in some situations SWIG would try to exit with the status set
to the number of errors encountered, but that's problematic - for
example if there were 256 errors this would result in exit status 0 on
most platforms. Also some error statuses have special meanings e.g.
those defined by <sysexits.h>.
Also SWIG/Javascript tried to exit with status -1 in a few places (which
typically results in exit status 255).
Previously code in the SWIG tool didn't handle allocation failures
well. Most places didn't check for NULL return from
malloc()/realloc()/calloc() at all, typically resulting in undefined
behaviour, and some places used assert() to check for a NULL return
(which is a misuse of assert() and such checks disappear if built with
NDEBUG defined leaving us back with undefined behaviour).
All C allocations are now done via wrapper functions (Malloc(),
Realloc() and Calloc()) which emit and error and exit with non-zero
status on failure, so a non-NULL return can be relied upon.
Fixes#1901.
Closes#89
Squash merge branch 'master' of https://github.com/wkalinin/swig into wkalinin-nested
By Vladimir Kalinin
* 'master' of https://github.com/wkalinin/swig:
CPlusPlusOut mode for Octave
nested class illustration
fixed "Abstract" flag for nested classes added an example enabled anonymous nested structs runtime test
porting
warnings disabled
porting fixes
java runtime tests ported
nested class closing bracket offset fixed
removed double nested template (not supported by %template parsing)
template_nested test extended
parent field made public
property access fixed
replaced tabs with spaces
warning W-reorder
deprecated warnings removed, derived_nested runtime test added
optimized string indenting
Nested classes indenting
nested classes docs
fixed the order in which flattened inner classes are added after the outer
Private nested classes were getting into the type table.
Java getProxyName() fix for nested classes fixes the case when nested classes is forward declared
Fix for a case when a nested class inherits from the same base as the outer. (Base class constructor declaration is found first in this case)
merge fix
nested C struct first immediate declaration incorrectly renamed sample fixed
tests updated to reflect nested classes support
Java nested classes support (1)
flattening should remove the link to the outer class
access mode correctly set/restored for nested classes
nested templates should be skipped while flattening (template nodes themselves, not expanded versions) also non-public nested classes should be ignored
If nested classes are not supported, default behaviour is flattening, not ignoring flag "nested" is preserved, so, the nested classes can be ignored by user
nested workaround test updated
template instantiated within a class is marked as nested for ignoring purposes
%ignore not applied to the nested classed, because "nested" flag is set too late
typedef name takes precedence over the real name (reason?)
unnamed structs should be processed for all the languages
nested C struct instances are wrapped as "immutable"
tree building
typedef declaration for unnamed C structures fixed
nested classes "flattening"
fixed %ignoring nested classes
renamed "nested" attribute to "nested:outer" added "nested" flag, to be used with $ignore (it is not removed while flattening) added nestedClassesSupported() function to the Language interface
renamed "nested" attribute to "nested:outer" added "nested" flag, to be used with $ignore (it is not removed while flattening) added nestedClassesSupported() function to the Language interface
tree iteration fix
dirclassname variable names unified memory issue fixed
merge error
ignore unnamed structs for C++
unnamed nested C structs naming & unnesting
class added to classes hash under typedef name
private nested classes skipped
test updated due to nested templates support
anonymous structs with inheritance fixed nested_class test to allow anonymous structs w/o declarator
tests updated: nested workaround removed from namespace_class.i propagated nested template declaration to the C++ file
injected members scope
nested tempplates fixes, nested structures in "C" mode parsing added utility function "appendSibling" (like "appendChild")
nested unnamed structures parsing fixes, access mode restored on nested class end, tdname is properly patched with outer class name prefix
memory management fixes
nested templates (1)
Nested unnamed structs
Nested class support (1)
Nested class support (1)
