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

If a newline has a backslash in front of it, then str_rd replaces it
with a space. However, the newline was in the original config file,
so the line number must still be incremented.
(cherry picked from commit 76d803bbb9)
Previously, it only pretended to rewrite the configuration file, so it
set or cleared OPT_MUST_SAVE but never changed or output any options.
Now, it actually sets the options when ELinks is loading the
configuration file. Also, when ELinks is rewriting the configuration
file, it now compares the values in the included file to the current
values of the options, and sets or clears OPT_MUST_SAVE accordingly.
(cherry picked from commit 054852ae23)
So, if elinks.conf contains a "set" command for an alias and ELinks
updates that, it now knows it doesn't have to append another "set"
command for the underlying option.
(cherry picked from commit 92b430f3dc)
So if ELinks is rewriting a configuration file that contains a "set"
command for a negated alias, then it properly writes the value of the
alias, rather than the value of the underlying option.
(cherry picked from commit c47d3798a3)
That is, let the setter function of the underlying option store the
negated value. Previously, redir_set used to tweak the value of the
option after it has already called the underlying setter.
(cherry picked from commit 2dbe6ec34f)
Also, replace OPT_WATERMARK with OPT_MUST_SAVE, which has the opposite
meaning.
Watermarking of aliases does not yet work correctly in this version.
Neither does the "include" command.
(cherry picked from commit 7cdbc908d8)
Previously, they were reset by smart_config_string(), which was not
called if the value of the option was saved by rewriting an existing
command in elinks.conf. Also, it is better to reset the flags only
after the file operations have actually succeeded.
(cherry picked from commit 6bd961246a)
Previously, ELinks set the OPT_WATERMARK flag in all deleted options
when config.saving_style was 2, thus mostly preventing them from being
saved. This had the unfortunate consequence that if you started with
no elinks.conf, set config.saving_style = 2, deleted some built-in
option (e.g. a URL rewriting rule), saved the settings, and restarted
ELinks, then the built-in option would reappear.
(cherry picked from commit ab8ef9698f)
Previously, if you did this in elinks.conf:
set document.dump.header = "\'\\"
then str_rd() failed to detect the end of the string.
(cherry picked from commit b216a21b79)
I was looking for code that handles OPT_COMMAND, so I grepped for it,
but did not immediately find this array. Next time, I will.
(cherry picked from commit f8863183b8)
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.
gcc-4.3 -O2 was complaining that http_got_header may use uninitialized
version.major and version.minor. That indeed happened with HTTP/0.9
servers, and the PRE_HTTP_1_1(version) check then had an undefined
result, so http->close could remain 0 even though it should have
become 1; fortunately, it was then set to 1 anyway, because there was
no Content-Length header. The undefined version was also saved in
http->recv_version, but it appears nothing ever reads that. So in the
end, the bug did not cause any symptoms at runtime, but the warning
broke the build on gcc-4.3 if ELinks was configured with --enable-debug.
(cherry picked from commit 5c0128d82d)
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.
If fdopen failed, save_textarea_file would free the filename, but it still returned the pointer to the filename. With this commit, save_textarea_file will return NULL if fdopen fails.
*fresult pointed to nowhere. On FreeBSD *fresult == NULL
and directories weren't displayed.
Check also if safe_write writes all data.
(cherry picked from commit 06bcc48487)
Previously, file extensions added or modified via the menu did not get
saved to elinks.conf when config.saving_style was 3 (the default).
This patch makes the file-extension dialog box call option_changed,
which then sets OPT_TOUCHED, so that the option appears modified in
the option manager and will be saved.
