The comment said "it is not possible to call kill_timer from a timer
handler." Sure, such calls used to crash occasionally, but that was
bug 868 and has already been fixed.
Without this patch, ELinks showed garbage at
<http://www.dwheeler.com/oss_fs_why.html> when bzip2 decompression was
enabled. safe_read() in bzip2_read() did not see all of the body
bytes that ELinks had received from the server. After bzip2_read()
received EAGAIN from safe_read() and returned 0, something skipped
1460 bytes.
decompress_data() apparently assumed that read_encoded() returning 0
meant the end of the file, and returned even though len still was
nonzero, i.e. it had not yet written to the pipe all the data that
the caller (read_chunked_http_data() or read_normal_http_data()) had
provided. The caller did not know this, and discarded the data.

*fresult pointed to nowhere. On FreeBSD *fresult == NULL
and directories weren't displayed.
Check also if safe_write writes all data.

libsmbclient's stdout and stderr interferred with ELinks's stdout
and stdin. That caused an assertion failure. Now the ELinks uses
different streams for processing of the smb protocol.
This reverts commit 7ceba1e461,
which is causing an assertion to fail if I open the same PDF
twice in a row, even if I cancel the dialog box when ELinks
first asks which program to run:
INTERNAL ERROR at /home/Kalle/src/elinks-0.12/src/session/download.c:980: assertion download && download->conn failed!
Forcing core dump! Man the Lifeboats! Women and children first!
But please DO NOT report this as a segfault!!! It is an internal error, not a
normal segfault, there is a huge difference in these for us the developers.
Also, noting the EXACT error you got above is crucial for hunting the problem
down. Thanks, and please get in touch with us.
Program received signal SIGSEGV, Segmentation fault.

There is a fix available but I don't trust it yet.
This syncs some changes (ie. -> e.g. etc.) from elinks-0.12 or beyond.
I noticed them while updating the web pages, and apologize that I will
not spent the time to attribute it to the individual commits.

The bug was reported by Paul B. Mahol on elinks-users. The example is
from the FTP site he provided:
ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES-ia64/
Message-ID: <3a142e750802262008l6fd55be5v44207bc4479dd3fc@mail.gmail.com>
(cherry picked from commit c069403b75)
... so all the tests with responses stretching multiple lines are
actually tested in their entirety.
(cherry picked from commit aa9a847c00,
resolving a conflict due to the use of get_test_opt)
On AMD64 apparently, off_t is long but ELinks detected SIZEOF_OFF_T == 8
and defined OFF_T_FORMAT as "lld", which expects long long and so causes
GCC to warn about a mismatching format specifier. Because --enable-debug
adds -Werror to $CFLAGS, this warning breaks the build. When both
SIZEOF_LONG and SIZEOF_LONG_LONG are 8, ELinks cannot know which type
it should use.
To fix this, do not attempt to find a format specifier for off_t itself.
Instead cast all printed off_t values to a new typedef off_print_T that
is large enough, and replace OFF_T_FORMAT with OFF_PRINT_FORMAT which
is suitable for off_print_T altough not necessarily for off_t. ELinks
already had a similar scheme with time_print_T and TIME_PRINT_FORMAT.
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.

Add a boolean protocol flag which says whether "//" in the path
part of an URI can be safely substituted with "/". Be conservative
and enable it only for file://, ftp:// and nntp[s]://. Other
can be turned on later, if needed.
Generalizes the fix from 58b3b1e752.
This reverts commit 4f0aaa166e
and insert check for the "//" -> "/" change only to occur for
file:// URIs. This fixes the recent reports on broken handling
of relative file URIs starting with "..".
<http://www.wikipedia.org/w/wiki.phtml?search=sue%20lawley>
incorrectly redirects to
<http://en.wikipedia.org/w/wiki.phtml?search=sue%2520lawley>
which searches for "sue%20lawley" rather than "sue lawley".
By using en.wikipedia.org directly, we avoid the server bug.
Prompted by an elinks-users post on 2007-07-27.
I asked on #wikimedia-tech, and www.wikipedia.org does always
redirect to en.wikipedia.org; it does not guess any other
language based on headers or IP addresses or such. Also, the
redirection exists only for compatibility, and skipping it
avoids a few roundtrips to the server. So this change is good
even if the server is eventually fixed.
