In document.forms, each struct form has form_num and form_end members
that reserve a subrange of [0, INT_MAX] to that form. Previously,
multiple forms in the list could have form_end == INT_MAX and thus
overlap each other. Prevent that by adjusting form_end of each form
newly added to the list.
Revert 438f039bda,
"check_html_form_hierarchy: Old code was buggy.", which made
check_html_form_hierarchy attach controls to the wrong forms.
Instead, construct the dummy form ("for those Flying Dutchmans") at
form_num == 0 always before adding any real forms to the list.
This prevents the assertion failure by ensuring that every possible
form_control.position is covered by some form, if there are any forms.
Add a function assert_forms_list_ok, which checks that the set of
forms actually covers the [0, INT_MAX] range without overlapping,
as intended. Call that from check_html_form_hierarchy to detect
any corruption.
I have tested this code (before any cherry-picking) with:
- bug 613 attachment 210: didn't crash
- bug 714 attachment 471: didn't crash
- bug 961 attachment 382: didn't crash
- bug 698 attachment 239: all the submit buttons showed the right URLs
- bug 698 attachment 470: the submit button showed the right URL

init_js_window_object() copies the alert, open, and setTimeout methods
from the window object to the global object. My fix for bug 846 on
2006-12-10 incorrectly made the corresponding C functions refuse to
work if they were not called as methods of the window object.
Commit 0b99fa70ca "Bug 620: Reset form
fields to default values on reload" made render_document() decrement
vs->form_info_len to 0 while vs->form_info remained non-NULL.
copy_vs() then copied the whole structure with copy_struct and did not
change form_info because form_info_len was 0. Both view_state
structures had form_info pointing to the same memory block, causing a
segfault when destroy_vs() tried to free that block a second time.
Reported by أحمد المحمودي.
elinks.keymaps.main["/"] = null;
used to crash ELinks with a segfault in JS_ObjectIsFunction.
Fix that by recognizing JSVAL_NULL explicitly and treating it as "none".
Likewise, if keymap_get_property would return "none" to ECMAScript,
return JSVAL_NULL instead.
The SpiderMonkey scripting module handles the "pre-format-html" event
by constructing a JSObject for the struct cache_entry and then calling
elinks.preformat_html(cache_entry, view_state) if such a function
exists. The problem with this was that each such JSObject kept the
struct cache_entry locked until SpiderMonkey garbage-collected the
JSObject, even if the user had not defined an elinks.preformat_html
function and the JSObject was thus never needed at all. To work
around that, the SpiderMonkey scripting module ran a garbage
collection whenever the user told ELinks to flush caches.
Remove the SpiderMonkey scripting module's use of object_lock and
object_unlock on struct cache_entry, and instead make the pointers
weak so that ELinks can free the cache_entry whenever it wants even if
a JSObject is pointing to it. Each cache_entry now has a pointer back
to the JSObject; done_cache_entry calls smjs_detach_cache_entry_object,
which follows the pointer and detaches the cache_entry and the JSObject
from each other.
This commit does not yet remove the workaround mentioned above.
Because http://elinks.cz/release.html is made from this file,
I think we'll have to list both 0.11.4.GIT and 0.12pre1.GIT
even though it's a bit difficult to explain which fixes are
in which releases.
The second argument of PERL_SYS_INIT3 should be a char ***
but ELinks was giving it a char *(*)[1].
Also, enlarge the array to 2 elements, so that my_argv[my_argc] == NULL
like in main(). PERL_SYS_INIT3 seems hardly documented at all so I'm
not sure this is necessary, but it shouldn't hurt.

There are warnings about casts in the Debian amd64 build logs:

The warnings in _nl_find_msg were caused by alignof, which I already
fixed. This commit ought to fix the gnutls_transport_set_ptr call in
ssl_connect. This warning did not yet happen in bug 464384 because
the others broke the build before it got that far.
This patch prevents handle_itrm_stdin() and clear_handlers(itrm->in.std) to be
called when -remote is set and in.std < 0.
It adds two assertions for in.std >= 0 in handle_itrm_stdin() and
unhandle_itrm_stdin().
May be a bad fix, please test and review.
[Added a NEWS entry. --KON]
Do not clear the IXON flag in termios.c_iflag.
Bug 54 did not actually ask for this flag to be kept,
but the cable I am using doesn't seem to have the handshake
lines connected right, so XON/XOFF is a must at 38400 bps,
at least until ELinks learns to send padding based on terminfo.
Any user who has bound actions to Ctrl+S or Ctrl+Q and finds that
they no longer work should just "stty -ixon" before running ELinks.
We don't have any default bindings for those keys, fortunately.
Actually, don't use the cfmakeraw function at all,
and don't look for it during configure either.
(cherry picked from commit 87f1661314
but moved the NEWS entry into the 0.12 section)
When setting the tty device to raw mode, save the VERASE character.
Later, compare incoming bytes to that.
This is somewhat complicated because "stty verase undef"
sets termios.c_cc[VERASE] = _POSIX_VDISABLE, and e.g. Linux
defines _POSIX_VDISABLE as 0 but that must not cause ELinks
to treat incoming null bytes as backspaces. Furthermore,
some systems may use different VDISABLE values for different
terminal devices, in which case _POSIX_VDISABLE is undefined
and ELinks must instead read the value from fpathconf().
It is unlikely because the standard members of struct sockaddr_in
(sin_family, sin_port, sin_addr) already require at least 8 bytes
and I don't know of any system that has size_t larger than that.
Besides, at least glibc pads the structure to 16 bytes.
When get_pasv6_socket was merged into get_pasv_socket on 2005-04-15,
the AF_INET6 of get_pasv6_socket was lost and the merged function
always returned AF_INET sockets. This then made getsockname fill
only part of the struct sockaddr_in6, and ELinks sent to the server
an EPRT command that had half the bits missing from the IPv6 address.
At least ftp.funet.fi then rejected the command, helpfully saying
what the address should have been.
This commit fixes active FTP over IPv6. Passive FTP was already fixed
in 0.11.3.GIT (887d650efe), on 2007-05-01.
