The previous check (integer > (off_t) integer * 10) did not detect all
overflows. Examples with 32-bit off_t:
integer = 0x1C71C71D (0x100000000/9 rounded up);
integer * 10 = 0x11C71C722, wraps to 0x1C71C722 which is > integer.
integer = 0x73333333;
integer * 10 = 0x47FFFFFFE, wraps to 0x7FFFFFFE which is > integer.
Examples with 64-bit off_t:
integer = 0x1C71C71C71C71C72 (0x10000000000000000/9 rounded up);
integer * 10 = 0x11C71C71C71C71C74, wraps to 0x1C71C71C71C71C74
which is > integer.
integer = 0x7333333333333333;
integer * 10 = 0x47FFFFFFFFFFFFFFE, wraps to 0x7FFFFFFFFFFFFFFE
which is > integer.
It is unclear to me what effect an undetected overflow would actually
have from the user's viewpoint, so I'm not adding a NEWS entry.

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.
The previous code displayed the wrong attributes if the combining
characters were at the end of an HTML link. For example:
<a href="#">trickỹ</a> more text <a href="#">second link</a>
(The characters in the first A element are "tricky" and U+0303
COMBINING TILDE.)
Here, when the cursor was not at the first link, ELinks displayed
the y-with-tilde cell as if it were not part of the link.
This happened because ELinks had already changed schar->attr
before set_line saw the space character after the link and
flushed document->combi[].
Combining characters requires a UTF-8 locale.
It slows down rendering. There is still the unresolved issue with
combining characters at the end of a document.
This patch wasn't heavilly tested. Especially a "garbage" input may cause
unpredictable results.
In the previous version, the first event that had KBD_MOD_PASTE
entered insert mode and was consumed for that; ELinks then inserted
the characters from the remaining events. Now, to make ELinks insert
the first character too, I'm changing things so that KBD_MOD_PASTE
does not cause insert mode to be entered; instead, ELinks inserts
those characters regardless of whether insert mode is on.
Since there is only one LED panel per terminal, redrawing for each session
is wasteful.
Furthermore, since one terminal can have many sessions (i.e. tabs), and
since the last session in the list might not be the current session, the
wrong LEDs might be drawn.
An easy way to demonstrate the bug is to enable ui.clock.enable, so that
the panel is redrawn every 100ms, and then to select a text field and enter
insert mode. Unless the current tab is the last tab, the insert-mode LED
will only briefly show that insert mode is enabled.
After copying the base session's viewstate, restore the ses->doc_view->vs
pointer.
This follows up on commit 65321923b9:
In setup_session, copy the viewstate for the new session from the base
session.
This fixes bug 977: When opening a javascript: link in a new tab, an
assertion on ses->doc_view->vs in ecmascript_protocol_handler would fail.
In init_remote_session, pass open_uri_in_new_tab a false argument for the based parameter so that the new tab does not get the old tabs current location in its history.
Because ELinks's CSS support is still so incomplete, some documents still render better if "display: none" is not honoured. Therefore, it is now honoured, unless document.css.ignore_display_none = 0, which is the default.
We have a while loop that checks token && token->type != '}' followed by an if statement that checks token && token->type == }. If the while loop exits, that either token is false or token->type == '}'; therefore, the if statement need only check token.
This patch adds support for:
- option document.css.media
- CSS @import "foo.css" tty;
- CSS @media tty { ... }
- HTML <link rel="stylesheet" media="tty">
- HTML <style media="tty">
This patch is attachments 395 and 396 from bugzilla.elinks.cz, which
are based on attachment 388 from bugzilla.elinks.cz. This new
version of the patch fixes conflicts with recent 0.13.GIT changes,
marks Doxygen commands with at-signs rather than backslashes, and
adds a few comments.

Go to the page with a few lines. Follow a link to a page with more lines.
Move cursor down, do not stay on a link.
Go back and do move-link-prev-line. This caused a segmentation fault.
