Avoid compilation error with GNUTLS 1.2.9:
/home/Kalle/src/elinks-0.12/src/network/ssl/ssl.c:258: error: implicit declaration of function ‘gnutls_priority_set_direct’
If the function is not available, use gnutls_set_default_priority instead.
Perhaps it'll work with bugzilla.novell.com, perhaps not.
- gnutls_handshake_set_private_extensions: Do not enable private cipher
suites that might not be supported by anything other than GNUTLS.
The GNUTLS 2.8.0 documentation notes that enabling these extensions
can cause interoperability problems.
- gnutls_set_default_priority: Explicitly disable OpenPGP certificates.
- gnutls_certificate_type_set_priority: Do not enable OpenPGP certificates.
The GNUTLS 2.8.0 documentation notes that OpenPGP certificate support
requires libgnutls-extra. Because libgnutls-extra 2.2.0 and later are
under GPLv3-or-later and thus not GPLv2 compatible, ELinks doesn't use
libgnutls-extra, so OpenPGP certificates didn't work anyway.
- gnutls_server_name_set: Do not tell the server the hostname from the URL.
This was supposed to let the server choose the appropriate certificate
for each name-based virtual host, but ELinks actually always sent just
"localhost", so it didn't work anyway. This will have to be revisited
when ELinks is changed to actually verify the subject name from the
server's certificate (ELinks bug 1024).
These changes should help ELinks negotiate SSL with bugzilla.novell.com.
[NEWS and commit message by me. --KON]
Yet another valiant wack at the beast. This one violates abstractions
a little less deeply, so maybe it will work better.
The last attempt caused a crash when a tab was cloned after the tab's
loading had been aborted.
(cherry picked from commit 76377d9714)
Kalle reported that after commit 5c96d430c9,
ELinks would crash if the document in the old tab was still loading when a
new tab was opened. The problem was that the new session's download.data
pointer was not updated to point to the session as doc_loading_callback
expects.
Instead of just calling render_document_frames, set up the download and
call load_uri.
(cherry picked from commit d6116ca83a)
In setup_session, use copy_location, add_to_history, and
render_document_frames instead of goto_uri and copy_vs to copy the base
tab's view state. By avoiding goto_uri, setup_session now bypasses MIME
checks, form post confirmations, malicious URL checks, and so on when
copying the base tab's current location and view state to the new tab,
so the new tab should get exactly what was loaded in the base tab.
This fixes bug 765: Opening a new tab can ask about the document of the
previous tab.

src/session/session.c:
Both elinks-0.12 and master had the ses->doc_view->vs
= vs assignment, but only elinks-0.12 had vs->doc_view
= ses->doc_view as well. Also, struct connection_state
had been added after the original patch.
I am not hooking these to "make test", for two reasons:
1. utf8_step_forward is inside #ifdef CONFIG_UTF8 and I don't see
how to make tests conditional on such options.
2. test/libtest.sh was copied from Git, which is under GPLv2-only.
Adding more dependencies on it could make ELinks more difficult
to relicense under GPLv2-or-later.
In the task.c line 517 there is:
if (is_in_progress_state((*download_p)->state)) {
if (have_location(ses))
*download_p = &cur_loc(ses)->download;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Here the download was changed. download->data and download->callback
were NULL after the assignment, but later in loading_callback
only download->callback had new value. download->data was still NULL.
In 0.13.GIT, the configure script sets disable_gnutls=yes if it
decides to use nss_compat_ossl. In recent elinks-0.12, the script
logs "explicitly disabled" if $disable_gnutls is set. Thus, merging
those together could have caused an incorrect claim to be logged.
Rearrange the logic to make it easier to extend to multiple libraries.
Code that deals with one library no longer needs to worry about each
alternative library separately. Instead just test and set the one
shared chosen_ssl_library variable.
While at it, get rid of openssl_withval, which merely mirrored the
with_openssl variable provided by Autoconf.
The configure script used to run libgnutls-config in order to find the
compiler and linker options needed for using GNUTLS, but GNUTLS 2.7
apparently doesn't ship that script any more. Use pkg-config instead.
GNUTLS 1.2.0 is the oldest version supported by ELinks, and that already
installs the gnutls.pc file required by pkg-config.
This commit also removes support for configure --with-gnutls=DIR.
The configure script used to look for libgnutls-config in DIR.
DIR thus had to be a directory where executable programs were installed,
and it's unlikely that gnutls.pc would be found there. So, any callers
that used this feature would have to be changed anyway, and they can as
well be changed to set the PKG_CONFIG_PATH environment variable instead.
Fix this error:
configure.in:1430: error: AC_SUBST: `[CONFIG_TRE]' is not a valid shell variable name
acinclude.m4:31: EL_LOG_CONFIG is expanded from...
configure.in:1430: the top level
autom4te: /usr/bin/m4 failed with exit status: 1
Reported by witekfl.
This check used to be in src/elinks.h. Move it to configure.in so
that (1) the result can be logged and (2) ELinks won't even link with
TRE if wchar_t prevents its use.
Also, rename HAVE_TRE_REGEX_H to CONFIG_TRE, to reflect that it is not
always defined if the header exists.
The previous version could display its progress like this:
checking for TRE... checking for TRE in pkg-config... yes
checking for TRE header and library... yes
no
Omit the outer "checking for TRE..." and "no" (which was untrue
anyway), unless --without-tre causes the inner checks to be skipped.

elinks-lite in Debian does not depend on any libraries (except
gnutls). Including this option will allow elinks-lite to be built
without libtre dependency.
At the end of the destroy_vs there two assignments vs->doc_view->vs = NULL and
vs->doc_view = NULL. In the setup_session the copy_vs left the vs "unbound"
with any variable. At least one of these two is wrong.
The AsciiDoc 7.1.2 configuration files included in the ELinks
source tree apparently aren't compatible with AsciiDoc 8.4.4:
[ASCIIDOC] doc/elinks.1.xml
FAILED: [listdef-bulleted] missing section: [listtags-None]
make[1]: *** [elinks.1.xml] Error 1
Fix this by including asciidoc.py from AsciiDoc 7.1.2 as well.
The build system now doesn't care at all whether the user has
installed some version of AsciiDoc or not.
When setting up default values for terminal options, use named
constants like TERM_VT100 or COLOR_MODE_16, rather than plain integers
like 1. This is just to make the source code easier to read and
perhaps more resistant to future bugs. The binary should not change.
If globhist_simple_search ran out of memory in stracpy(search_url), it
could leave gh_last_searched_title pointing to freed memory and cause
a crash in the next call. Fix by not freeing gh_last_searched_title.
It is then possible to have gh_last_searched_title and
gh_last_searched_url pointing to strings from different searches;
but that was already possible if stracpy(search_title) failed.
Because this bug occurs only in out-of-memory situations and I don't
think ELinks in general has been properly tested in those, the fix is
perhaps not worth mentioning in NEWS and backporting to elinks-0.11.
If the parent parameter of get_dom_node_list_index referred to a node
that did not have children, then get_dom_node_list called by it could
return the address of a null pointer, and get_dom_node_list_index would
then pass that null pointer to get_dom_node_list_pos, which would crash.
That would be the same kind of crash as the one in get_dom_node_child.
It never happened in practice though: because all calls are in the form
get_dom_node_list_index(node->parent, node), the list must contain at
least the given node, and the pointer cannot be null. The documentation
of get_dom_node_list_index allows arbitrary nodes as arguments however,
so it's best to add a check.
struct dom_node contains a union that contains various structs that
have members of type struct dom_node * in them.
get_dom_node_list_by_type returns the address (struct dom_node **) of
one of those members, or NULL. However the member itself can also be
NULL if no nodes have been added to the list and the list has thus not
yet been allocated. (add_to_dom_node_list lazily allocates the lists.)
get_dom_node_child did not expect a null pointer there and crashed, as
shown in bug 1071. Fix by adding a check so that it treats a NULL list
as an empty list.
C99 6.7.4p3 and 6.7.4p6 set some constraints on what can be done in
inline functions and how they can be declared. In particular, any
function declared inline must also be defined in the same translation
unit. To comply with that, remove inline specifiers from function
declarations in header files when the functions are not also defined
in those header files.
Sun Studio 11 on Solaris 9 is stricter than C99 and does not allow
references to static identifiers in extern inline functions. Make the
configure script detect this and define NONSTATIC_INLINE accordingly
in config.h. Then use that in the definitions of all non-static
inline functions.
Document the restrictions and this scheme in doc/hacking.txt.
Documentation strings of most options used to contain a "\n" at the
end of each source line. When the option manager displayed these
strings, it treated each "\n" as a hard newline. On 80x24 terminals
however, the option description window has only 60 columes available
for the text (with the default setup.h), and the hard newlines were
further apart, so the option manager wrapped the text a second time,
resulting in rather ugly output where long lones are interleaved with
short ones. This could also cause the text to take up too much
vertical space and not fit in the window.
Replace most of those hard newlines with spaces so that the option
manager (or perhaps BFU) will take care of the wrapping. At the same
time, rewrap the strings in source code so that the source lines are
at most 79 columns wide.
In some options though, there is a list of possible values and their
meanings. In those lists, if the description of one value does not
fit in one line, then continuation lines should be indented. The
option manager and BFU are not currently able to do that. So, keep
the hard newlines in those lists, but rewrap them to 60 columns so
that they are less likely to require further wrapping at runtime.
