SpiderMonkey was updated to mozjs24. If you want to build elinks
with ecmascript support, you must compile using g++ with -fpermissive .
There is a lot of warnings.
There are some memleaks in ecmascript code, especially related to JSAutoCompartment.
I don't know yet, where and how to free it.
Debian does not support mozjs24, so I'm going to gradually update SpiderMonkey version.
Weak points:
- alignof
- js problems
Todo:
- make js work with C++ and mozjs-17
- then mozjs-24
- then mozjs-52
- then mozjs-60
- decrease number of warnings
Make u2cp_() map code points U+0080 to U+009F via strange_chars[] even
if the target codepage is UTF-8. This helps with buggy web pages that
use ’ when they mean ’. This change does not affect how
ELinks decodes raw bytes 0x80 to 0x9F in HTML.
u2cp_() is used only via the u2cp and u2cp_no_nbsp macros.
Possible side effects of this change at each use of these macros:
* get_translation_table(): Not affected because it does not call u2cp
if the target codepage is UTF-8.
* get_entity_string(): Numeric character references are affected, as intended.
Character entity references are not affected because entities[]
does not define any entities in the U+0080...U+009F range.
* kbd_field(), term_send_ucs(), field_op(): Affected. It is no longer
possible to enter code points U+0080...U+009F from the terminal.
This should not be a problem in practice because those would be
control characters anyway and should therefore be filtered by the
slave process (which doesn't yet recognize them; bug 777).
After viewing a page with Big5 charset and next a page with UTF-8
charset iconv was used, so slows down a bit.
Now iconv is used only for those charsets, which has the iconv
bitfield set.
I am not hooking these to "make test", for two reasons:
1. utf8_step_forward is inside #ifdef CONFIG_UTF8 and I don't see
how to make tests conditional on such options.
2. test/libtest.sh was copied from Git, which is under GPLv2-only.
Adding more dependencies on it could make ELinks more difficult
to relicense under GPLv2-or-later.
This check used to be in src/elinks.h. Move it to configure.in so
that (1) the result can be logged and (2) ELinks won't even link with
TRE if wchar_t prevents its use.
Also, rename HAVE_TRE_REGEX_H to CONFIG_TRE, to reflect that it is not
always defined if the header exists.
C99 6.7.4p3 and 6.7.4p6 set some constraints on what can be done in
inline functions and how they can be declared. In particular, any
function declared inline must also be defined in the same translation
unit. To comply with that, remove inline specifiers from function
declarations in header files when the functions are not also defined
in those header files.
Sun Studio 11 on Solaris 9 is stricter than C99 and does not allow
references to static identifiers in extern inline functions. Make the
configure script detect this and define NONSTATIC_INLINE accordingly
in config.h. Then use that in the definitions of all non-static
inline functions.
Document the restrictions and this scheme in doc/hacking.txt.
