When the current element or a parent has display:none, the display_none
flag is set and no new element should be added to the viewport. For form
inputs, instead of always adding the Embed to the viewport, we only do
it if display_none is not set. The Embed is still registered as an input
in the form, so it will continue to send the proper form values to the
server.
For complex buttons that can contain nested elements inside, we switch
to a dummy button that doesn't have a Textbox and rely on the logic at
html.cc to avoid creating more child elements until the display_none is
unset.

Breaking the loop causes missing leaks that are otherwise visible when
closing the tab.

Allows detecting memory leaks on exit automatically.

A copy of the buffer is done while injecting the content for about:cache
and about:dicache, so the Dstr needs to be free'd after.

From Livio Baldini Soares:
> Let me clarify a little bit about what the dicache is.

> This is how Dillo works. When you ask for a URL (be it a root URL,
> like a HTML, or an image embedded in a page), it looks it up in a
> _memory_ cache. If it's already there it returns the content of the
> cache, and if not it makes a connection to retrieve that URL.

> But there is a complication with respect to images. The images which
> are downloaded need to be decompressed to be displayed (that is,
> transformed from their original format, jpeg, gif, etc, to a bitmap
> format). So for images, first the dicache (_d_ecompressed _i_mage
> cache) is checked, then the cache, then finally it is retrieved from
> the site. The problem with dicache is that it eats up a *LOT* of
> memory, and the only benefit is the processing time of transforming
> from the original format to the bitmap. That's why the default is NO.

The dicache holds the decompressed buffers for each image and it often
is the main cause for memory consumption in Dillo. The current algorithm
for evicting entries waits until a image has no references and at least
three pages were opened before removing the entry.
|
|
The internal network cache holds entries for all the URLs fetched by
Dillo, and it only grows over time. It is convenient to be able to see
what elements are being currently stored so we can have choose a better
criteria if we decide to remove entries to avoid a huge memory usage
over time.
The entries are generated every time the page is requested, so it always
reflects the current state.

Open the Home page or the Bookmarks in a new tab if the button is
pressed with middle-click, following the same behavior for hyperlinks.
|
|
Allows jumping directly to a given tab. It encourages a low number of
tabs opened, otherwise it will exceed the 1 to 10 range.

When loading http://elpis.ws and then the issue 10, several images are
requested via the data: URL which in turn causes many calls to the DPI
datauri plugin, and it seems some may fail. When the DPI server fails to
reply, an OpAbort is received by the CCC, but is ignored when it comes
from the server side. This leaves the connection entry stale, and when
navigating backwards, an attempt to read a free chunk of memory causes a
crash.
Instead of ignoring the OpAbort, we handle it as if the CCC had received
an OpEnd event, which propagates the received operation to the chain and
then removes the connection.

In NetBSD the default CA certificate bundle for OpenSSL is located at
/etc/openssl/certs/ca-certificates.crt, so we include it in the default
search list so it works out of the box.

The IPv6 support is stored in the config.h header file, instead of being
passed with the -D flag, so it is easier to read from version.cc.

Adding the extra flags to search Mbed TLS in CFLAGS and LDFLAGS directly
inhibits AC_PROG_CC from injecting the usual -O2 and -g flags. Instead,
we add them to MBEDTLS_* set of variables which are only used to locate
Mbed TLS. Then we pass them to the Makefile via AC_SUBSTAC_SUBST().
We also move the LIBSSL_* flags to be early on the order of dillo_LDADD,
so that extra -L flags which can be injected from fltk-config or other
programs, don't accidentally point to /usr/lib or a similar location
where it could race with another installation of Mbed TLS.
This mechanism won't work for cases in which Mbed TLS has libraries
installed in a location other than the default search path, but works
for Arch Linux and Gentoo because the symlink them to the default search
path, even if they are installed in a different location.

A server may return the Content-Disposition in elements of a page like
images, which would otherwise trigger several "save as" dialogs.

Follows the behavior of so many other programs by copying the current
text selection into the clipboard with Ctrl+C. Selecting text continues
to copy it into the primary selection.
Fixes: https://github.com/dillo-browser/dillo/issues/228
|
|
Selecting text in the page copies only to the primary selection. Copying
links via the context menu now places the URL both in the primary and
clipboard selections so it can also be pasted with Ctrl+V.

This one requires a copy of the string, but it is easier to follow.
|
|
Instead of keeping a escaped flag, we simply check again both the
previous and current character for non-backlash and quote. As the
filename can be empty if we don't get a maching quote, we stop there.

For now it allows building the unit test without linking problems. A
more long-term solution is to split the code into separate modules that
can be tested more easily.

to open links in new tabs. It also allows mixing it with the shift

nsvg__isspace uses strchr on a NUL terminated string, so it returns
true for the NUL terminator. Other uses of nsvg__isspace account for
this by checking for NUL first; I've followed the same pattern here.

Allows the user to define additional entries in the link menu which will
execute the given program/script. Each actions is defined using the
"link_action" option. The link URL is stored in the $url enviroment
variable and the current page in $origin, so the user can customize how
do the handling.
Here is a simple example to add three new entries:
link_action="Debug variables:echo url=$url origin=$origin"
link_action="Open in MPV:mpv $url"
link_action="Open in Firefox:firefox $url"
The command is spawned in a forked process using the system() call,
which uses the shell to expand any variable. In particular, the $url
variable is set to the current URL being opened.

Add the target commit.h as a dependency of version.o, so it gets
generated before being included in version.cc, otherwise when doing a
parallel build it can fail.

Compare the commit used in the last rebuild to determine if it has
changed, rather than using a phony target which always causes a rebuild.

The returned value from Fl::version() is a floating point number like
1.0303, not 10303, so we correct it to follow Fl::api_version().

When git is available, records the git commit in the dillo binary, so
dillo -v reports the version and the commit. Otherwise only the release
version is reported (as we do now).
The commit is *always* recomputed when "make" is called. This allows
switching branches, doing a dirty rebuild and still get the correct
commit with "dillo -v".
Using AC_INIT() doesn't update the commit when the source is already
configured.
