This ensures that no other string can have the same address. It
probably never was a problem though, because the strings to which it
can be compared either are allocated from the heap or are in
strings[][] which already has unshared storage.

The decision isn't up to me, but I think this is a good idea. Here's a
patch that would update the documentation and hooks.py, as well as hooks.c.
FYI, if this patch is applied then anyone who's still trying to use a
goto_url_hook that expects a second argument will get a "Browser scripting
error" dialog box that says:
An error occurred while running a Python script:
TypeError: goto_url_hook() takes exactly 2 arguments (1 given)
As commit 7db8abf6e7 does for Lua
and the document info box, change the Python scripting backend's
current_document and current_header APIs to use document->cached
instead of find_in_cached so the currently displayed document
will be used rather than the latest version of the document.
The numbering of document.dump.color_mode and terminal._template_.colors
is now the same regardless of compile-time options, unlike in previous
versions. Therefore this version of ELinks may interpret a configuration
file differently from previous versions even if compiled with the same
options. This is unfortunate but the alternatives (keeping the numbering
dependent on configuration options; defining separate options that use
the new numbering; starting the numbers from 10 or so and recognizing the
previous ones only for compatibility) seem even worse.
This does not conflict with querying the palette from xterm (bug 890)
because although those palettes would have to be modifiable, they
would be terminal-specific rather than global.
Convert each byte of them to UCS_REPLACEMENT_CHARACTER. This may not
be the optimal solution but at least it ought to be safe. Also raise
an internal error if the value read from utf8char_len_tab[] is out of
range.
Note that ELinks is still using the RFC 2279 definition of UTF-8 and
thus allows characters up to 0x7FFFFFFF, even though RFC 3629 has
changed the maximum to 0x10FFFF.
This fixes parse_ftp_number to use off_t instead of long to store its
(intermediate) result and return type. It also introduces an OFFT_MAX type
"limit" that is used for validating the size of the parsed number.
A test-case for was added in 37c9bf3f75 to
test-ftp-parser and the patch has been confirmed to fix the test-case by
adamg and me. This closes bug 899, which is a duplicate of debian bug
403139.
I do not fully understand this code, but I am sure skipping characters
like this is a bug, and correcting it seems to fix bug 826 (too small
table for double-cell characters). I don't see any similar bugs in
other parts of set_hline.
The patch is from bug 826, comment 4, attachment 308. The warning
there about unicode_to_cell(UCS_NO_CHAR) still applies but this patch
does not make the situation worse. I have logged a separate bug 901
about those calls.
cleanup_python and python_done_keybinding_interface called by it
now reset the PyObject *python_hooks, *keybindings variables back
to NULL when they release the references. Without this change,
dangling pointers left in those variables could cause problems
if the Python scripting module were deinitialized and reinitialized.
It looks like such reinitialization is not currently possible though,
because enhancement request 73 (plugins support) has not yet been
implemented.
Before it was only to get the password when the user name was also
requested. This fixes FSP access to password protected directories.
The problem was discovered by Witold and mentioned in the post to
elinks-dev with the message-id: <20061209204151.GA32758@pldmachine> on
2006-12-09.
Now the currently displayed version of the current document,
rather than the latest version of the current document, will be used
for the document info box and the current_document() Lua function.
This allows code to use document->cached instead of
find_in_cache(document->uri), thereby increasing the likelihood
of getting the correct cache entry.
This should fix Bug 756 - "assertion (cached)->object.refcount >= 0 failed"
after HTTP proxy was changed.
Patches for this were written by me and then later by Jonas.
This commit combines our independent implementations.
The configure script checks whether it is possible to compile a use of
POPpx without an n_a variable; if not, the source code then defines
those variables. This is slower than including Perl's patchlevel.h
and comparing the version numbers to 5.8.8 but I expect this to be
more reliable as well.
Before this patch, init_python would crash trying to set up elinks.home
at the Python side. Now it uses None as the value in that case.
Also, init_python no longer adds "(null)" to $PYTHONPATH.
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.
This reverts baf7b0e91d:
Fix segfaults caused by ruby scripting (gentoo bug #121247).
which reverted 5145ae266a:
Change the Python, Ruby, and SEE hooks for pre-format-html to work
properly now that they are given a non-NUL-terminated string.
and also makes the Ruby hooks interface generally use rb_str_new(str, len)
in favor of rb_str_new2(str) to avoid relying on NUL-terminated being
handled correctly by Ruby. Also, it was wrong for the preformat hook which
is not always handed a NUL-terminated string. Finally, the gentoo bug
(http://bugs.gentoo.org/show_bug.cgi?id=121247) is currently reopened which
suggests that the previous fix was not correct.
If CONFIG_UTF8 is not defined, then text_end is not used, and GCC
could warn about that. Because configure can add -Werror to CFLAGS,
the warning could then cause the whole build to fail.
The error was:
sgml-parser.c: In function 'print_indent':
sgml-parser.c:99: warning: field precision should have type 'int', but argument 2 has type 'long unsigned int'
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.
As draw_textarea_utf8 loops over each character of the textarea content, it
checks whether the character is on the screen; draws it if so; increments
the screen co-ordinate; and updates the position in the textarea text.
The last step was being skipped when the character was not on the line,
so a line would be drawn from the beginning, even if the left edge of the
textarea is off the screen.
Closes: Bug 835 - Text in textarea is unaffected by horizontal scrolling of
document in UTF-8 mode
If utf8_char2cells isn't told where the string that contains
the given UTF-8 character ends, it computes that itself. Two users
of utf8_char2cells, format_textutf8 and split_line, were calling
utf8_char2cells in a loop without providing the end of the string,
resulting in numerous calls by utf8_char2cells to strlen.
With this patch, format_textutf8 and split_line each find the end
of the string once and provide it to utf8_char2cells.
This particularly improves performance with textareas, since
format_textutf8 is called multiple times each time the user interacts
with the textarea and when it must be redrawn.
Closes: Bug 823 - Big textarea is too slow with CONFIG_UTF8
The quote_level was decremented unconditionally and could become negative
resulting in a negative index after applying "modulus 2". Reproducable
with an HTML file contianing "</q>".
