Implement new heartbeat code to catch runaway execution of document
ECMAScript code. The old code uses JS_SetBranchCallback which is
deprecated in new versions of SpiderMonkey. The new code uses setitimer(2)
and the JS_SetOperationCallback and JS_TriggerOperationCallback interfaces,
introduced in SpiderMonkey 1.8.1. Compatibility with both the old
JS_SetBranchCallback and the new interfaces is maintained.
Except if they have external handlers.
When ELinks receives an event from a terminal, move that terminal to
the beginning of the global "terminals" list, so that the terminals
are always sorted according to the time of the most recent use. Note,
this affects the numbering of bookmark folders in session snapshots.
Add get_default_terminal(), which returns the most recently used
terminal that is still open. Use that in various places that
previously used terminals.prev or terminals.next. Four functions
fetch the size of the terminal for User-Agent headers, and
get_default_terminal() is not really right, but neither was the
original code; add TODO comments in those functions.
When the user chooses "Background and Notify", associate the download
with the terminal where the dialog box is. So any later messages will
then appear in that terminal, if it is still open. However, don't
change the terminal if the download has an external handler.
When a download gets some data, don't immediately check the associated
terminal. Instead, wait for the download to end. Then, if the
terminal of the download has been closed, use get_default_terminal()
instead. If there is no default terminal either, just skip any
message boxes.
JSObject instances of input_class now again contain a private pointer
directly to struct form_state. This pointer is cleared or updated
when appropriate.
Rename src/ecmascript/spidermonkey/util.c to
src/ecmascript/spidermonkey-shared.c and compile it also when
CONFIG_SCRIPTING_SMJS is enabled but CONFIG_ECMASCRIPT_SPIDERMONKEY is
not. Then use its functions from src/scripting/smjs/ too. Move the
corresponding declarations, as well as the inline functions needed by
src/scripting/smjs/, from src/ecmascript/spidermonkey/util.h to
src/ecmascript/spidermonkey-shared.h.
ELinks is nowadays using two JSRuntimes and SpiderMonkey has bugs that
make it crash in such use. To work around them, ELinks will need to
be changed to use only one JSRuntime. I am planning to define and
initialize that JSRuntime in src/ecmascript/spidermonkey-shared.c,
now that it's compiled whenever either of the modules is enabled.

The following files also conflicted, but they had not been manually
edited in the elinks-0.12 branch after the previous merge, so I just
kept the 0.13.GIT versions:
doc/man/man1/elinks.1.in
doc/man/man5/elinks.conf.5
doc/man/man5/elinkskeys.5

Pass the session with some get_opt_* calls. These are the low-hanging fruit. Some places will be difficult because we don't have the session or for other reasons.
The previous code cast the integer (long actually) to void * and gave
that to JS_SetPrivate. This did not work because JS_SetPrivate
expects pointers to be aligned and replaces the least significant bit
with a tag. By using JS_SetReservedSlot instead, we get control of
the jsval conversions and can store the integer properly.
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.
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.
Previously, html_special_form_control converted
form_control.default_value to the terminal charset, and init_form_state
then copied the value to form_state.value. However, when CONFIG_UTF8
is defined and UTF-8 I/O is enabled, form_state.value is supposed to
be in UTF-8, rather than in the terminal charset.
This mismatch could not be conveniently fixed in
html_special_form_control because that does not know which terminal is
being used and whether UTF-8 I/O is enabled there. Also, constructing
a conversion table from the document charset to form_state.value could
have ruined renderer_context.convert_table, because src/intl/charsets.c
does not support multiple concurrent conversion tables.
So instead, we now keep form_control.default_value in the document
charset, and convert it in the viewer each time it is needed. Because
the result of the conversion is kept in form_state.value between
incremental renderings, this shouldn't even slow things down too much.
I am not implementing the proper charset conversions for the DOM
defaultValue property yet, because the current code doesn't have
them for other string properties either, and bug 805 is already open
for that.
This change does not fix any bug, but the SMJS builtin classes use
negative tinyids already, so I presume this is the preferred practice.
At least it means the tinyids won't have to be renumbered later if
some of these objects are changed to behave as arrays.
If ECMAScript code does obj[42], then the getProperty or setProperty
function of the JSClass of obj gets 42 as the property ID and must not
treat that as an internal error.
The getProperty and setProperty functions of a JSClass must not assume
that the obj parameter points to an instance of that class. It might
instead point to another object that merely has an instance of the
class in its prototype chain. Thus, do not assert that JS_InstanceOf
returns true there. Instead, run the check even with CONFIG_FASTMEM,
and just return JS_FALSE if it fails.
Surrogates are now treated the same way as out-of-range characters
like U+110000; if a link has such an access key, then the ECMAScript
accessKey property cannot be read. It seems currently impossible to
set such an access key though, because accesskey_string_to_unicode()
doesn't support multibyte characters yet.
The two copies of delayed_open in src/ecmascript/spidermonkey/window.c
and in src/ecmascript/see/window.c are identical, so move them
to src/terminal/tab.c and eliminate the duplication.
Until the last change in src/ecmascript/see/window.c, the two copies
of delayed_goto_uri_frame in src/ecmascript/spidermonkey/window.c and
in src/ecmascript/see/window.c were identical. That change applies to
both versions, so move the newer one to src/session/task.c and eliminate
the duplication. Also move struct delayed_open to src/session/session.h.
This changes the init target to be idempotent: most importantly it will now
never overwrite a Makefile if it exists. Additionally 'make init' will
generate the .vimrc files. Yay, no more stupid 'added fairies' commits! ;)
Ditch the building of an archive (.a) in favour of linking all objects in a
directory into a lib.o file. This makes it easy to link in subdirectories
and more importantly keeps the build logic in the local subdirectories.
Note: after updating you will have to rm **/*.a if you do not make clean
before updating.
All objects defining $(OBJS) will get them and *.a deleted during
make clean.
The all, clean and install rules now implicitly imply their -recursive
counterparts - those will just do nothing in case of $(SUBDIRS) not
defined, so that's ok.
The root makefile is converted as well as some leaf Makefiles. This
also brings in the required infrastructure and adjusts configure.in
appropriately.
I converted only makefiles containing no configurable stuff, since
that'll require more consideration yet.
