Re: [Dillo-dev]HTTPS certificate support

by Garrett Kajmowicz

I accepted nearly all of the changes you requested. In recards to switch statements, in the updated function there is a need to deal with 3 possabilities, thus I kept the switch statement. The rest of the locations I converted to braced if statements which use else statements to return an abort code as the alternative option. Though computer science dictates that there should be only one entry and one exit point from a function, using break calls not only hurts my eyes, it produces code which is less readable. Thus all locations where a function might exit for one purpose I have the code to exit for all purposes, with a catch-all return -1 at the function. Personal preference. Once again, please evaluate. - Garrett Kajmowicz

I spent quite a few minutes looking for such a function, but I guess I just missed it in the API reference. With the function name, I know what I am looking for and will rewrite immediately. I'm going to redo this whole thing and resubmit. Part of my problem is trying to maintain multiple versions, working after I submit one patch but before it is applied. My school mates hate me for it - I crank out code like a mad man! - Garrett Kajmowicz

[Dillo-dev]HTTPS certificate support

by Garrett Kajmowicz

OK - this patch backs out a few trivial changes which were made about 2 patches ago due to code redundancy and are no longer needed. This patch detects self-signed certificates and gives the user the option to permanently trust them, autosaving to the .dillo/certs directory. Please give this a whirl, and then commit it. Let me know when done so I can while my current devel tree clean and get a new copy - this way I don't have to manually correct all of the spelling errors with each patch :-) - Garrett

No, I have not checked that out. I will take a look at it to see how it looks. I personally figure that OpenSSL is more likely to be installed on a given system than GnuTLS (which is an issue) and more thoroughly tested.

The certificate seems to be trustable to me, but the lock is an image that is sent wether or not the connection is secure. In short, it is just there to make the customer feel better. I'll have more stuff for you shortly. - Garrett Kajmowicz

There're several issues about this, I made an answer for the soon-to-be-publised Dillo FAQ. <q> ----------------------------------------------------------------- Q: Internationalization and Localization (i18n & l10n) The main problem for doing this is that the underlying library that Dillo uses (GTK+-1.2.x), doesn't support UTF-8 character rendering. Dillo currently supports ISO-LATIN1 and works internally with this encoding. GTK+-2.x supports UTF-8 but it's too big to be used with Dillo. After a long feasibility analysis FLTK was chosen as the next widget library for Dillo. Among other things FLTK supports UTF-8 and before Dillo is ported to it, i18n and l10n is frozen. There're some patches that enable Dillo to view some other encodings though. Beware that as Dillo works internally in Latin1, these patches do break some functionality and don't expect them to work flawlessly (specially with FORMS and entities). That's why they're not included in the main source tree. OTOH, we know they're worth to people longing to see their native language. These patches may apply to an old version of Dillo. Please don't hesitate to write to the original authors if you update them. Problems with these patches don't belong to our mailing list. If you update the patch, and the original author is no longer interested, you may tell us to update the link. Russian (also suports other encodings): http://bobuk.ipost.ru/packages/dillo/ Japanese: http://oldeee.see.ed.ac.uk/~rjt/dillo/japanese.html Polish: http://www.chemia.px.pl/cgi-bin/archiwum.cgi#dillo Some comments about Hindi and Chinese: these languages need an special technology to render, and they're not currently supported under FLTK, but the possibility is open. This is, the best path to add support for them in Dillo, when it runs over FLTK, is to add Chinese/Hindi support directly into FLTK. The FLTK developing team should be contacted for the details.

Modularizing functionality is usually a good > idea. Yes it is! This is sort of a tradeoff... For instance html.c does all its parsing with a function very much like Get_attr_value(). One alternative that I've been thinking of for a long time, is to just parse HTML tags once and return something like a: struct pair { char *attr_name; char *attr_value; }; struct pair *parsed_tag; Or the same pairs in a simple list: char **parsed_tag; with NULL marking the end. The advantage is that tag-parsing is done once, but now the caller has to go through the list to find out what attr_names are present.

Different things come my way everyday, and I have to manage lots of things in different areas. Don't get scared though. This patch took some time to commit because I had to think of things that affect the other plugins. OTOH having a patch in the CVS doesn't give it a lot of exposure. The number of people using Dillo from CVS and testing is smaller than one expects. We usually tend to work on our local trees until something is stable enough for broader testing before making the commit. Things should go faster in the future... Cheers Jorge.-

Something like: > > a_Dpiutil_dialog_parse_answer(...) I created a specific function because in this case a numerical response can be expected, and thus returning a char answer requires the programmer to do more work for this specific value.

I have written a fair bit more code (now I have to merge changes *ugh*). The issue is probably a lack of issuer certificates. Currently the https module checks /etc/ssl/certs. I'm trying to think of a way to put the directory in the configure script, but that will have to wait a little while. Right now I'm working on allowing self-signed certificates to be accepted long-term. OpenSSL has some weird ideas on how to do things. > > gives me the warning dialog. Is this OK? Warnings are OK. I'm adding more and more code in to handle all possible error conditions. Previously there was no warning if there was a problem - just a likely insecure connection. Now the system is warning on everything, and hopefully will be able to deal with a large number of these problems in code giving *useful* error messages. One thing at a time, though. Side question, do you have a regular Dillo mailing list view-parse-evaluate-and-commit schedule? I know you prefer smaller patches to larger patches, but it gets a little annoying for me when I submit something and I don't know when it will be reviewed and commited. The time doesn't bother me, but if I know your schedule I can schedule my work appropriately. Thanks. - Garrett Kajmowicz
