JS_CallFunction does not support closures in SpiderMonkey versions
earlier than 1.8. Test case:
elinks.keymaps.main["!"] = function() {
elinks.load_uri("http://www.eldar.org/cgi-bin/fortune.pl?text_format=yes",
function (cached) { elinks.alert(cached.content); });
}
elinks.keymaps.main["/"] = null;
used to crash ELinks with a segfault in JS_ObjectIsFunction.
Fix that by recognizing JSVAL_NULL explicitly and treating it as "none".
Likewise, if keymap_get_property would return "none" to ECMAScript,
return JSVAL_NULL instead.
This reverts commit c33d195ff4.
ELinks no longer needs to collect garbage in this situation
because it can now free cache entries even if the corresponding
SMJS objects remain.
The SpiderMonkey scripting module handles the "pre-format-html" event
by constructing a JSObject for the struct cache_entry and then calling
elinks.preformat_html(cache_entry, view_state) if such a function
exists. The problem with this was that each such JSObject kept the
struct cache_entry locked until SpiderMonkey garbage-collected the
JSObject, even if the user had not defined an elinks.preformat_html
function and the JSObject was thus never needed at all. To work
around that, the SpiderMonkey scripting module ran a garbage
collection whenever the user told ELinks to flush caches.
Remove the SpiderMonkey scripting module's use of object_lock and
object_unlock on struct cache_entry, and instead make the pointers
weak so that ELinks can free the cache_entry whenever it wants even if
a JSObject is pointing to it. Each cache_entry now has a pointer back
to the JSObject; done_cache_entry calls smjs_detach_cache_entry_object,
which follows the pointer and detaches the cache_entry and the JSObject
from each other.
This commit does not yet remove the workaround mentioned above.
gcc-4.3 -O2 was complaining that http_got_header may use uninitialized
version.major and version.minor. That indeed happened with HTTP/0.9
servers, and the PRE_HTTP_1_1(version) check then had an undefined
result, so http->close could remain 0 even though it should have
become 1; fortunately, it was then set to 1 anyway, because there was
no Content-Length header. The undefined version was also saved in
http->recv_version, but it appears nothing ever reads that. So in the
end, the bug did not cause any symptoms at runtime, but the warning
broke the build on gcc-4.3 if ELinks was configured with --enable-debug.
The following is in the HTML 4 standard
(<http://www.w3.org/TR/html401/interact/forms.html#push-button>):
push buttons: Push buttons have no default behavior. Each push
button may have client-side scripts associated with the element's
event attributes. When an event occurs (e.g., the user presses the
button, releases it, etc.), the associated script is triggered.
Currently, a button such created by such HTML as "<input type="button"
value="foo" />" submits the form by default in ELinks. According to
the above, it shouldn't.
Do not retain changed values in form fields when the user reloads. Doing
so can be confusing or even cause data-loss when new default values are
specified in the updated document. For example, when editing an article on
Wikipedia, one loads the edit page for the article, makes and submits
changes, goes back to the edit page to make further modifications, and
reloads to get the new article text. Before this change, reloading the
edit page would not update the textarea on the page with the new article
source, which can lead one (and has led me) to make changes to the original
version of the article by accident.
This fixes bug 620.

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.

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.
The second argument of PERL_SYS_INIT3 should be a char ***
but ELinks was giving it a char *(*)[1].
Also, enlarge the array to 2 elements, so that my_argv[my_argc] == NULL
like in main(). PERL_SYS_INIT3 seems hardly documented at all so I'm
not sure this is necessary, but it shouldn't hurt.

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

This bug was revelead while using bittorrent.
For filenames started with a dot and two slashes .//
the open_bittorrent_file returned -1 and set errno to EEXIST.
elinks --config-help used to sort options like this:
document.history
document.history.global
document.history.global.enable
document.history.global.max_items
document.history.global.display_type
document.history.keep_unhistory
Now it'll instead be:
document.history
document.history.keep_unhistory
document.history.global
document.history.global.enable
document.history.global.max_items
document.history.global.display_type
i.e. all the options listed under a subheading are children of the
tree named by it. This makes elinks.conf(5) look saner.
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 reverts commit d0be89a16c, and thus
restores the ELinks 0.11 behaviour: always copy the data to a
temporary file before passing it to a MIME handler, even if the
"file:" URI scheme is being used. Previously, ELinks 0.12.GIT passed
the name of the original file directly to the handler. That was more
efficient but unfortunately gave the wrong result with local CGI.
The commit being reverted also claims to partially fix bug 238
(caching of local files). That bug is still open.
Currently, when ELinks passes the name of a local file to an external
MIME handler program, it encodes the name as a URI. Programs
typically do not expect this, and they then fail to open the file.
This patch makes ELinks instead quote the file name for the shell.

Currently, when ELinks passes the name of a local file to an external
MIME handler program, it encodes the name as a URI. Programs
typically do not expect this, and they then fail to open the file.
ELinks should instead quote the file name for the shell.
Unfortunately, Debian has lines like this in /etc/mailcap:
audio/mpeg; xmms '%s'; test=test "$DISPLAY" != ""
If ELinks were changed to replace the %s with e.g.
'/home/Kalle/doc/Topfield/How to upgraded the Firmware(English).pdf'
(quotes included), then the quotes would cancel out and the shell
would split the file name into multiple arguments. That could even
provide a way for malicious persons to make ELinks run arbitrary
shell commands.
The examples in RFC 1524 all have %s without any quotes.
Debian has two bug reports about the quoting behaviour:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=90483http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=221717
This patch therefore tries to detect whether the %s has been quoted
already, and remove the quotes if so. That way, the next patch will
be able to safely add its own quotes. This removal of quotes applies
only to mailcap files; MIME handlers defined in elinks.conf should
already be in the format preferred by ELinks.

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.

Previously, file extensions added or modified via the menu did not get
saved to elinks.conf when config.saving_style was 3 (the default).
This patch makes the file-extension dialog box call option_changed,
which then sets OPT_TOUCHED, so that the option appears modified in
the option manager and will be saved.

Git describe happily picks whatever annotated tag is closest to the
commit. I make use of many annotated tags that correspond not to
ELinks releases but rather to patches posted in bugzilla or sent in
email. So with git describe, the About window can display e.g.
"email/witekfl/2008-02-29-2-g705acfa-dirty", which is not the intended
use of this tag.
In the "next" branch of git.git, git describe apparently supports a
--match option with which it could be made to consider ELinks releases
only. However, that option is not yet in any released version of Git,
and anyhow ELinks should support older versions too.
Instead of using git describe, just show the full SHA-1, like
cg-commit-id would. The About dialog box also displays VERSION
from configure.in, so it isn't even particularly useful to show
the name of the latest tag. (The commit count might help though.)
The build ID now includes both last tagged version, commit generation
since last tagged version, as well as the leading characters of the
commit ID and a flag for dirty working tree.
