No worries :-)

Yeah, but I prefer to move to a new file when the format is more stable,
so you can keep your rules intact. Now I'm experimenting.

Yeah, maybe I could also make it like this so you can specify a program
directly:
actions="Open with external tool:/path/to/the/handler.sh default $URL"
actions="Open as audio:/path/to/the/handler.sh audio \"$URL\""
actions="Open with MPV:mpv $URL"
actions="Open with Firefox:firefox $URL"
But this won't work well when the URL has characters that are
interpreted by the shell.
It "should" be like:
actions="Open with external tool:/path/to/the/handler.sh default \"$URL\""
actions="Open as audio:/path/to/the/handler.sh audio \"$URL\""
actions="Open with MPV:mpv \"$URL\""
actions="Open with Firefox:firefox \"$URL\""
But is quite ugly. And I'll have to check if you can still inject some
command in the URL, which would be dangerous.

Yes, I have also experienced this annoyance. It may be nice yes, not
sure how complex to implement.

I think for very long text files this may continue to choke Dillo. Maybe
you could add a external tool that pipes it to more(1) or less(1).

By default, no extra options. As you add the actions they appear on the
menu. We may want to distribute an example handler for users to have a
reference.

Thanks a lot for the explanation!
Although it may be difficult to get a FLTK2 package in the
distro because FLTK2 doesn't have a stable release yet. I mean,
if policies mandate not to include alpha or beta libraries, we're
out...
It'd be good to know this (for Fedora, Ubuntu and Debian at
least). That way we can ask the FLTK team about their schedule
plans.

[PATCH v2] Unveil patch
by a1ex＠dismail.de
Hi,
Here is version 2 of my unveil patch. Many thanks to Rodrigo for his
kind assistance!
Improvements:
- Unveil is disabled by default. It can be enabled using:
configure --enable-unveil
- There is now a dUnveil() wrapper which simplifies the code and error
handling
- Locale check and custom cursor icons unveil fix
To-Do:
- Add prefs parsing to plugins to get 'save_dir' (may need help here)
- Add a dillorc pref to enable/disable unveil (same issue as above)
- Localize wget and $AUTHORITY
- A few other items from my previous to-do list
Regards,
Alex

Did the new test in configure.in work?
I assume not because of the silence.
You wrote:

I assume you set LDFLAGS=-L/usr/local/lib...
but this is expected to be done by the test at configure.in:96.
The test can fail though! Would you mind posting the output of:
cpp -v
in your system.

I think the flicker can be avoided, but that won't stop the content from
"jumping" in the fullscreen case.

I think the advantage of a menu bar is that it's easily visible, what functionality
is available. Advanced users will probabely use shortcuts.
But you are right. I forgot about the context menus. The link and image menu
only makes sense as a context menu.

Thank you for your response.
The begin of my web bug adventure was some curiousity as I gamed around
with http://livehttpheaders.mozdev.org. I found some strange things, and
momentarily felt like the guy in "The blue velvet", finding an cut ear
and come into touch with an strange and eval world outside a wardrobe.
The real eval things can only be done by javascript - so dillo is on the
save side.
It may be of general Interest: I found as a countermeasure the plugin
ghostery for firefox. ghostery has a large list of known web bugs and
can block it. Most of that software one may find is googles urchin.js,
but ggogle has a new software ga.js. There was even launched "Turn Key
Web Analytics In A Box" on Friday, December 18, 2009, see
http://www.coradiant.com/news/091209_analyticsbox.htm. The List of web
bugs you can find:
http://code.google.com/p/ghostery/source/browse/trunk/firefox/ghostery-stat…
One may check out a read-only working copy anonymously over HTTP:
http://code.google.com/p/ghostery/source/checkout
As I just pointed out, a dillo user cannot be tracked by any javascript
code. But even a simple Web Bug with a http-rquest to a tracking server
can get a lot of Information about the request AFAIK that is client IP
address, certainly the request date/time, the page requested, HTTP code,
bytes served, user agent, and referer. So the tracker knows the URL of
the page containing the bug and allows the server to determine which
particular Web page the user has accessed. But more, the URL of the bug
can be appended with an arbitrary string in various ways with extra
information to identify the loading conditions of the bug. This extra
information can be added while sending the page or by JavaScript scripts
after the download (but as ponted out - no Javascript with Dillo). Web
bugs can also be used in combination with HTTP cookies (if there are
any) like any other object transferred using the HTTP protocol.
One might say, use a proxy. But I found that nearly all of the free
proxys are real trojans and sending such web bugs, most often in the
advertising pictures. I asked a couple of the providers of free proxy
services. The usual answer was, that they do not send web bugs, but the
bad advertisers do. And usually they offered ma thei payed service that
is free of advertising. And very often that web bug requests will NOT be
send via the proxy!!
You sent me an option switch to forbid dillo to request another domain
as that of the actually used page:
http://lists.auriga.wearlab.de/pipermail/dillo-dev/2009-September/006844.ht…
How can I patch Dillo in this way?
It might be useful to have that as an option in Dillo, I am shure not
every user is comfortable with that restriction.
Seasons greetings

Updated unveil patch
by a1ex＠dismail.de
Hi,
Here is a new patch. I have done quite a bit more work on this and
think it may be close to completion.
The '~/Downloads' directory has been unveiled to match the behavior of
Firefox and Chromium on OpenBSD, but Dillo's default of '/tmp'
continues to work as well.
I have also made sure everything works fine when there is no ~/.dillo
directory, Dillo can create it, and also can access the system defaults
in '/usr/local/etc/dillo'.
dpid is also now unveiled, as well as all of the stock plugins except
hello.dpi, I didn't see any point to that.
Here are some other tests which I have run:
- Regular browsing works fine
- Connect to an FTP site and download a file, also view a text file and
view an image
- Open a text and image file from /tmp and ~/Downloads
- Add/remove bookmarks
- Download a file to /tmp and ~/Downloads
- Save a page to /tmp and ~/Downloads
- View source still works
- Fonts and cursor icons are working correctly
- data: uri works correctly with text and images
So far everything seems to be fine. I will keep testing, but would
really appreciate some help with reviewing this, there could be some
edge-cases which I missed.
Regards,
Alex

Thank you for the effort! I think this is getting in good shape.
Some preliminary comments:
Even if you compile for OpenBSD, unveil() was not introduced until
OpenBSD 6.4, so there is the possibility that is not available for an
user building Dillo for an old OpenBSD.
I recommend you add a configure switch (in configure.ac) to enable or
disable unveil(). By default you can keep it disabled and let the user
enable it manually, until we have more feedback to make it enabled by
default. Maybe by defining ENABLE_UNVEIL? You can take the --enable-svg
and ENABLE_SVG as an example.
Dillo from OpenBSD ports may enable it by default adding
--enable-unveil, so users test it without having to do any extra
configuration.
You should also make a dillorc configure option to enable/disable the
unveil feature in runtime, so it can help debug problems. You can make
the dillorc option enabled by default, which will only take action when
unveil support has been compiled in.

The download directory is set in the dillorc configuration file, and can
be any other place. Is it viable to read the configuration first and
then unveil the appropriate directory?

This is also controlled by the prefix variable, which can be set to any
other directory than /usr/local. This should be passed to the code to
form the complete path, an example is the DILLO_DOCDIR which is defined
as:
-DDILLO_DOCDIR='"$(docdir)/"'
In src/Makefile.am.
You'll want to use the $(sysconfdir) autoconf variable:

As this won't be a simple patch, I suggest you open a PR in GitHub, so
the CI can compile your patch revisions for multiple platforms and pass
the tests. Otherwise I would have to spend the time to do it myself.
I'm thinking if we can automate those tests in the CI. Probably we would
need to add OpenBSD as a target first, as we only have FreeBSD.

The err() function is non-portable, please use Dillo MSG* macros or
perror() + exit(). This should be caught by the CI.
Also, ensure the indentation is kept at 3 characters (not my decision).
Would it make sense to add an unveil() wrapper? This would make it
easier to integrate with other platforms than OpenBSD (and you also get
the error checking in one place). Something like this:
void dUnveil(const char *path, const char *perm)
{
#ifdef USE_UNVEIL
#ifdef __OpenBSD__
if (unveil(path, perm) == -1) {
MSG("unveil(%s, %s) failed: %s\n", path, perm, strerror(errno));
exit(1);
}
#endif
/* Other platforms... */
#endif
}
Not sure if we can make all those repeated calls into something that we
can reuse for all dpis and dillo main too.

Not sure if you may need other user-defined places for fonts.

You should find wget by locating it in the $PATH, not assuming it would
be here. Users may place their own wget binary somewhere else and this
would break the downloads.

The .Xauthority file should be read from $AUTHORITY and then from there

I'll suggest adding another rule to protect ~/.dillo/dillorc from
modification.

Same here, the downloads directory is given by the dillorc, you cannot
assume it will be set there.

Notice wget may need ~/.netrc to access FTP files. But maybe it is good
to leave it out.

Plugins can also be found on the dpi_dir directory defined by the user
