To reduce code duplication, src/protocol/file/cgi.c no longer parses
connection->uri->post on its own but rather calls the new function
http_read_post_data(), provided by src/protocol/http/http.c. The same
code is now also used for POST requests that do not include files.

Check also if safe_write writes all data.
(cherry picked from commit 06bcc48487)
If the user opens the same file again after it is in the cache, then
ELinks does not always open a new connection, so download->conn can be
NULL in init_type_query(), and download->conn->cgi would crash.
Don't read that, then; instead add a new flag cache_entry.cgi, which
http_got_header() sets or clears as soon as possible after the cache
entry has been created.
CGI scripts are distinguishable from normal files. I hope that this
fixes the bug 991. This commit also reverts the previous revert.
(cherry picked from commit 7ceba1e461)
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.

AFAIK, all bugs in it have been fixed. Some bugs may still be lurking
but they are more likely to get caught if compression is enabled.
I also replaced COMP_NOTE with static text because xgettext does not
support macros in the argument of N_.
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>

... 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.
Previously, struct string was used here. However,
bittorrent_fetch_callback does not initialize response.magic,
and parse_bittorrent_tracker_response changes response->source
to point to data that must not be freed. So the util/string.h
functions are not actually safe to use on these objects.
For this reason, it is safer to use a separate type.
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.
(cherry picked from commit a25fd18e56)
The compression support in ELinks has always been buggy, with some large pages
failing to decompress and containing garbage at the end instead. However,
with the recent attempts to fix the compression support, it has been actually
made *so* buggy that not only these cases seem to occur more often, but in
some cases, the page is just silently chopped and no content visible; in other
cases, "Resource temporarily unavailable" is displayed. Etc.
The compression support got now to the point where it is so awfully unstable
that it is actively harmful to have it enabled by default. I've been burnt by
it several times already and once made a very serious error because of page
being chopped silently.

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.
There were conflicts in src/document/css/ because 0.12.GIT switched
to LIST_OF(struct css_selector) and 0.13.GIT switched to struct
css_selector_set. Resolved by using LIST_OF(struct css_selector)
inside struct css_selector_set.
This patch changes normalize_uri() to no replace "//" with "/" in URIs. This
fixed this bug but will also lead to possibility that duplicate entries can
exist in ELinks' cache. ELinks might be able to detect in another way by
hashing the content or something.

And reorder the characters in the string given to strcspn(), to match
their expected order in the URI. This is also how strcspn() is called
elsewhere in uri.c.
