Enabling https is a piece of cake, but some sites would lock dillo (the https dpi doesn't support multiple requests for the same site yet), and it's _not_ secure because it's not validating the certificates. Go try to explain that to a user, and sign a dillo version with https enabled. We can't because we're commited to security. We can let the user choose later to loose all protection, but this is his decision. (same as with the linux kernel). > Have you considered moving dillo to a community project model?

It was sad for me to re-read some posts by one guy that came with lots of radical ideas (not code), as rewriting the IO, eliminating the dillo plugin system, eliminating the CCC control chain "nightmare". (this is writing a different browser) He whined a lot and was very rude sometimes. Finally he decided to start a fork (IIRC), that in his view, would be much better than official Dillo. The fork never happened. Where's that code? Unfortunately what he said, more or less convinced some people in dillo-dev. From above it made sense. OTOH, he never realized that the CCC structure wasn't about just passing data, but about parallelism! That's why IMHO experienced developers tend to consider what the core team of any project thinks. We all know the core team may make mistakes, but they talk from experience and have deep knowledge of the systems they develop. It's also well known that when a core developer leaves, it's a _BIG_ loss. You can certainly find great developers elsewhere, buy no one will have the specific knowledge and experience of the one that leaves. It takes time to get there. Note: Oh, there were more brags (someone here remembers the one that bashed me and promised a much better and complete Dillo for windows in six months?) Years have passed since... Note2: making a patch and maintaining it are different things. Note3: making a patch that works, and one that fits with the design are also different things. The second one has less side effects and is easier to maintain. > I only know that I want dillo to succeed and replace firefox, the so-called > lightweight browser. I wish Dillo to succeed.

HTML/CSS is > the most basic combo for a browser anyway, I think. Different people tend to prioritize differently. For instance, the embedded industry needs Javascript to develop custom GUIs and sometimes also for a certain site they _have_ to support. The soothing fact for CSS in Dillo is that the internal widget style design was made for CSS. So it's a matter of gluing it together. Once again: manpower > As for JavaScript, what pages worth reading need JavaScript to > work? With the lack of dillo-dev manpower, this is a feature > I don't really miss. I'm not fond of Javascript either; it's a big security hole, but I also understand that it's a good way for developing WEB based GUIs for networked services. > Tabs, on the other hand, are extremely useful - I dream of the day > they come to dillo, making it able to have many pages rendered at > once (each with dillo's lightning speed). Yes, they're useful. I used to enjoy tabs in the window manager (fluxbox), but I also understand there's plenty of people without tabs in the window manager. The main reason for not coding tabs already in the official dillo is that there were higher priorities. The tabs patch was a several-features in a huge combo that the author was not willing to split. The good news of this story is that you can get that patchset from a compilation by kiyo on what's regarded as the "i18n misc" dillo: http://teki.jpn.ph/pc/software/index-e.shtml I find this compilation a very good thing to have, bacause users get what they want while we can work on a more long-term viable dillo (see rationale in my former posts). > > Frames are evil, everybody knows that.

Unfortunately not. :-( We gave that conference with Sebastian at FOSDEM 2005, and it had the plus of some live demos. One of them was a CSS prototype! Unfortunately on the next conference (LSM 2005, which is on video available from dillo.org) I was alone, and this DEMO wasn't presented. The demo consisted of a page with a link to its CSS stylesheet; the interesting part was that CSS was applied on-the-fly! This is: Dillo started normal incremental rendering (no CSS), and when the CSS stylesheet arrived later, and while still loading the page, in a blink it changed to show the CSS style, and continued with page rendering until it fully arrived. FWIW, while in Germany we discussed how to design scripting support. Now that Dillo produces a DOM it's a matter of using dpi to communicate with the scripting engine. A prototype was developed too. The main point is lack of manpower/funds. We can _not_ continue developing without time (spare time is unrealistic for such a complex project as this). That's why I've struggled to find a way to fund full time development for at least the two core developers. When finally a couple of companies were willing to invest, the "risk management" factor came in and stopped it. I don't know how to surpass this problem (see my previous email for more details). -- Cheers Jorge.-

For instance, the https is disabled by default and has to be enabled in the source code. Most users perhaps take a binary from some RPM or somewhere, so it stays default most of the time. It would really be nice if this was enabled/disabled by means of a "switch" and one did not have to recompile the whole source code. I must say that this does not solve the dollars question, but this is an issue worth considering. I doubt that you can get commercial vendors involved in this effort? The only other option is contributions, and even that is perhaps finite, especially if stuff people would like to see in their favorite browser is not going to show up. So, that leaves the contributions in terms of time and effort. Have you considered moving dillo to a community project model? I know that there are core developers and they could vet things submitted, but it would be better if there were more contributor developers who submitted their improvements. Something like, for instance, the R project in statistical computing. Or for that matter, octave or xemacs and the like.

I also think that CSS is the most missing feature - while a well written page using CSS looks good even without it, many pages just rely on being CSS-interpreted (or look ugly). HTML/CSS is the most basic combo for a browser anyway, I think. As for JavaScript, what pages worth reading need JavaScript to work?

I almost forgot how to write english when i do not write it in a long time. > The subject matter is complex, so I'd advice you to: take your > time, re-think, be more careful with your english, and to try to > express the ideas as clearly as possible. Ok, second try(i have changed a pair of things): The general ideas are to enhance dpid to manage DPIs using services (Like documentation suggest) and to add code to dillo to implement protocols DPIs (without hardcoding them in dillo core), mime handlers DPIs and maybe scripts languages DPIs and content encodig DPIs(now encodigs DPIs are in doubt after your mail) Dpid will need configuration lines(in dpidrc) to associate server name with DPI path(A dpi dir based path allow a DPI to serve more that one service(in this proposal a javascript DPI will serve protocol_javascript, script_javascript and maybe mime_text/javascript services)). When dillo finds a protocol that it not handle in core (currently it handle http:, about: and dpi:) it ask for a service for that protocol(to dpid) and dpid returns the DPI from the configuration file(really a socket to comunicate with it). For the service name dillo add the protocol name to the "protocol_" string. The lines in dpidrc for current services can be this: protocol_file=file/file.dpi protocol_ftp=ftp/ftp.filter.dpi protocol_https=https/https.filter.dpi protocol_data=datauri/datauri.filter.dpi I think i will allow the use of '*' to match any(even none) char until end of string in the configuration file. '*' will be checked last. It can be used by a ProtocolNotSupported.dpi that show an error or a page with protocols DPIs to download. The dpidrc line can be like this: protocol_*=misc/ProtocolNotSupported.dpi For mime types it works similar. When the user clicks on a link or uses the url bar to view a mime type not handled by dillo the mime type is addeded to the "mime_" string to get the service name(dillo currently handles mime_text/html, mime_text/plain, mime_text/*, mime_image/gif, mime_image/jpeg, mime_image/png). When a not handled mime type is open because a page load dillo add the "_inlined" string to the previous string(example: For a bmp file used like image in a html page dillo will try the mime_image/x-bmp_inlined service) The use of '*' wildcard allow the use of one DPI to manage both services with only a configuration line if user wants. About mime type check/detection i am thinking on diferent options (mime detection/check go before mime DPIs) 1a. Fixed service called for pages without mime types and ocet/stream (using this like unknown mime type) that returns a detected mime 1b. Fixed service called for pages without mimes and for a list of configured mime types in dillorc 2a. Check service per mime type with service names like mime_check_MIME/TYPE. Dillo send actuall type so the DPI handling the service can do something if detected mime is diferent from the server sended one.(ask the user, ignore error, stop load ...) 2b. Like 2b, but only ask for a list of mimes configured in dillorc Scripts and content encoding work similarly. For more details i can send how the dpi tags will be and more about dillo-DPIs communication and dillo internal changes. > With regard to gzip encoding: zlib can do gzip decoding, and as > it is already linked in Dillo, gzip decoding can be implemented > inside Dillo (not using a dpi).

I unknown if i can implement content encoding in dillo internals so i will move it after dpid changes on implementation complex. I hoppe it is more clear now. Diego

Beware, your first mail is very hard to read an understand (I don't understand it for instance). The subject matter is complex, so I'd advice you to: take your time, re-think, be more careful with your english, and to try to express the ideas as clearly as possible. With regard to gzip encoding: zlib can do gzip decoding, and as it is already linked in Dillo, gzip decoding can be implemented inside Dillo (not using a dpi). This also avoids multiple dpi passes. For instance with dpi- decompress, gzipped isolatin2 would require one dpi pass for uncompress and another for latin2 to utf8. Inside-Dillo decoding also allows the idea of having a compressed cache in the future. -- Cheers Jorge.-

Although I certainly regard the "i18n" patch-gathering as a good thing for the user, IMO dillo-gtk1 is a dead end from the development point of view (even if the gathered patches were in line with the rest of dillo's design, which is not the case). GTK1 is an abandoned library, it has become the much bigger, slower and capable GTK2, precisely because it was not suited for solving certain "desktop" problems. You can read Owen Taylor's "Internationalization in GTK+" paper for a more solid basis on i18n design decisions (Owen is one of the main authors of GTK1 and GTK2). http://developer.gnome.org/doc/whitepapers/gtki18n/index.html It can be thought that Dillo "i18n" would have more hope if ported to GTK2. Following this line, we made some benchmarks, investigated in more depth, I had some emails with Owen, we had a discussion in the mailing list, and it turned out that: * GTK2 could double Dillo's footprint. * GTK2 has different expose model that woul require a redesign of the incremental rendering inside Dillo. * Dillo would become much slower and resource hungry. If Dillo becomes slower and has a bigger footprint, its main advantages start to dissapear when compared with let's say Firefox or Opera. In that case even I'd prefer to wait a bit longer for Firefox to start and then have a featureful browser. Dillo's main advantage is a tradeoff of features for speed. If the speed edge disappears, what do we have? In short, after lots of investigation we decided to port Dillo to FLTK2 (Although there's plenty of information about this in the mailing list, I realize it would be good to recapitulate this story and make this information together with future plans available from one page in our site. This mail is the first step in that direction). With regard to Javascript, yes we also agree that we need to support some scripting language (ECMA or whatever). We've developed in this direction too (For instance we have the DOM code almost ready, and dpi can provide the link to the script interpreter; we even have developed a prototype for scheme). Tabs are easy to add too, and although I hate frames, they should be supported (sigh). BTW, I always had this in mind and that's why it was easy to make a frames patch. The networking code was already designed for the parallelism this task requires. It's a matter of implementing its rendering. Somehow people tend to believe that features are not there because the core team doesn't want them. Or even because they do not have room in a minimalistic browser. This is _not_ true. The main reason is lack of manpower. The other reasons are the GTK1 issue explained above and that these patches were not in line with the rest of the design, and that they break several things too (I've always asked authors to let their users know what each patch breaks). Having another design idea is valid, but it can't be pushed against those who think different (see LKML for examples! ;-). Forks had been announced but none thrived. > I also believe that Dillo shouldn't try to get CSS support; the last > thing I want is yet another browser with buggy CSS that I have to > design around.

We think Dillo needs CSS, so don't panic dillo-dev subscribers! :-) As a matter of fact, the widget style structures inside Dillo are shaped for CSS, and we presented a CSS parser prototype at FOSDEM 2005. Merging the CSS parser into the current tree would start CSS support. As for your concerns, disabling this is a piece of cake. > Anyway, these are just my 2 millicents.

For instance, there're plenty of embedded-focused companies that are interested, or already working with Dillo. They seem to prefer to wait for us to develop, with a view to lower costs, rather than to contribute (patches or money) or fund some development. These are the cheap companies. Other companies have interest and money to fund and foster Dillo development. The problem here is that managers prefer to make a choice for the "tried and true" and not to risk their jobs in the company in case of failure. I don't know yet how to solve the second problem. Any help is welcomed. BTW, this list has hundreds of subscribers. Please ask your questions, and send your ideas. If the core developers can't work full time on Dillo development, we'll not be able to keep the pace to chase this moving target of web browsing and Dillo will slowly die. Sebastian has a job and almost no time. If things don't change, I'll be in the same situation very soon. -- Cheers Jorge.- PS : Flames are not allowed in this mailing list.

Re: [Dillo-dev] Problems with gziped content encodings pages and proposal

by Diego Sáenz

Hello again. I have started to code my proposal. I have a little patch with the easiest part (dillo protocol part) so people can test it if they want. The patch is highly experimental. Dpid is not modified so (until it(the most complex part)) DPI tree and names of protocols DPIs will be break. It can be solved with a few moves and renames, but do not try it in a non test system if you do not known what are you doing. The patch works with current cvs. After compiling a dillo with the experimental protocol patch when dillo finds a url that do not start with http: or about: it will ask to dpid for a service called protocol_PROTOCOL-PART-OF-URL (examples: protocol_ftp for ftp urls, protocol_data for data urls , protocol_javascript for javascript urls(if you delete the code in html.c that intercepts javascript), ...). I will use protocol_https for examples from now. How dpid is not changed it will exec ~/.dillo/dpi/protocol_https/protocol_https.dpi or $dpi_lib/dpi/protocol_https/protocol_https.dpi (in the case that the file was there when dpid started) The changed dpid will exec the user selected DPI for that service when done. Until that If anybody want to play with this code apply the patch, compile with care(do not install it for example), create a DPI(a filter script one for example) in .../dpi/protocol_YOUR-PREFERED-PROTOCOL/protocol_YOUR-PREFERED-PROTOCOL.filter.dpi , stop and restart dpid and test pointing compiled dillo to YOUR-PREFERED-PROTOCOL:WHATEVER-YOU-WANT I have make a script for javascript urls to test it(see upper comment). I will try to code a more complex part (mime) now. Diego.
