This is a further precaution against reading a pointer from the wrong
type of object. All of the JS_GetPrivate calls were already protected
with JS_InstanceOf checks if assertions are enabled, and many of them
also if assertions are not enabled.
screen_driver_change_hook was comparing only strlen(name) characters
and ignoring the '\0'. To reproduce the bug in ELinks 0.11.3 and
ELinks 0.12.GIT:
- Run TERM=screen elinks.
- In another terminal, run TERM=scr elinks. Quit this slave ELinks.
- Open the terminal options dialog and set 16 colors.
- Open the option manager and change the terminal.scr.colors option to
1 and back to 0.
- Note that ELinks no longer displays colors.
That bug could be fixed just by using len+1 instead of len. However,
there is also another bug: memcmp may compare the specified number of
bytes, even if some of the earlier ones differ; thus, it could in
principle read past the end of the malloc block and thereby crash
ELinks. Using strcmp may be a little slower but I do not believe it
could become a bottleneck.
Introduce get_opt() to do the tedious work of getting the right
argument for options expecting them and handles both '--opt=arg'
and '--opt arg'. As a side effect it also removes an unneeded
assignment of the source string for stdin.
Works with both bash and dash. This reintroduces the fix to the
test-sgml-parser-basic test, and also fixes test-sgml-parser-incremental
and test-sgml-parser-lines, which Witek has reported as failing.
Remember the index of struct form_state in vs->form_info
instead of the pointer to it. The pointer may change,
the index is persistent.
The field ecmascript_obj of the struct form_state is unused.
Use it for the actual I/O only. Previously, defining CONFIG_UTF8 and
enabling UTF-8 used to force many strings to the UTF-8 charset
regardless of the terminal charset option. Now, those strings always
follow the terminal charset. This fixes bug 914 which was caused
because _() returned strings in the terminal charset and functions
then assumed they were in UTF-8. This reduction in the effects of
UTF-8 I/O may also simplify future testing.
