Gmail textareas
by james.from.wellington＠gmail.com Oct. 24, 2016

Oct. 24, 2016

Hello all, I have a work-around, so this isn't urgent. In view of recent events, keep caring for yourselves. Gmail sizes some text areas weirdly, as (CSS) width:80ex, and they disappear from view. I've tried two fonts, and the disappearance is complete in both cases. A cut down example is attached. The diff to suppress the disappearance is: --- gmail-compose-14.html 2016-10-21 21:06:01.000000000 +1300 +++ gmail-compose-15.html 2016-10-21 21:10:41.000000000 +1300 @@ -18,7 +18,10 @@ .th a:link, .th a:active, .th a:visited{text-decoration:none} .bn td{border:1px solid #FAD163} .ct textarea, .ct input, .ct select{font-family:arial,sans-serif;font-size:100%} + .compose .mi{width:80ex;font-family:arial,sans-serif;font-size:100%} +.compose .mi{width:100%;font-family:arial,sans-serif;font-size:100%} + .compose .i, .search .i{width:99%;font-family:arial,sans-serif;font-size:100%} .qr textarea{width:80ex;font-family:arial,sans-serif;font-size:100%} .qr input{font-family:arial,sans-serif;font-size:100%} The immensely crude work-around is the following, as a .gdbinit: ---------------- break 'StyleEngine::setClass' break main commands 2 cond 1 (0 == (int)strcmp(klass, "mi")) cont end commands 1 set klass = "i" cont end run ---------------- I'm open to hints about where to look for the effect of width on multiline text resources, but really I'm lost.

Sad news
by jcid＠dillo.org Oct. 21, 2016

Oct. 21, 2016

Hi, I'd like to inform our users and contributors, that we're mourning the loss of a friend, and core dillo developer. He was with us along the road for 16 years or so. A brilliant, and dedicated person, sharing his talents with us, the main architect of Dillo widgets, a reserved person with altruism and a ludic sense of humor. He will be missed as a person, friend, and fellow developer. Sebastian passed away in late September this year, Fare thy well, in your future endeavours outside this realm! -- Jorge.-

Startup time of the latest dev versions.
by johnfound＠asm32.info Sept. 19, 2016

Sept. 19, 2016

I am using Dillo as a help viewer of my IDE, because it has really short startup times and pressing F1 I get instant access to the documentation. Recently I tried to compile and use the recent development versions from the hg repository, because of the recent changes in the rendering and the general improvements in the browser. But unfortunately, the startup time seems to be increased and now I have to wait 2..3 seconds for browser to start and to show my help files. Is such slow startup time side effect of some changes that will be fixed some day, or it is kind of compromise, because of other improvements and this way will persists in the project from now on? Or (what is pretty possible) I messed something with the compilation? -- http://fresh.flatassembler.net http://asm32.info John Found <johnfound at asm32.info>

Entry in cookiesrc locks Dillo up
by nick＠linicks.net Sept. 16, 2016

Sept. 16, 2016

Hi All, I frequent a Slackware Pi forum, and decided to get Dillo to remember my log-in details with cookies. The URL is (in my bookmarks file): http://forum.fatdog.eu/viewforum.php?f=30 If I add: forum.fatdog.eu ACCEPT in my cookiesrc file, then start Dillo, click on the above said link in bookmarks, Dillo locks up and the only way out is to kill it from the command line. Any ideas on this? Or am I being stupid? Nick -- Gosh that takes me back... or is it forward? That's the trouble with time travel, you never can tell." -- Doctor Who "Androids of Tara"

Get Dillo to honour target=_blank
by nick＠linicks.net Aug. 29, 2016

Aug. 29, 2016

Hi all, How easy (or hard) would it be to get Dillo to honour the URL/FORM directive 'target="_blank" to get URL/CGI data returned in a new tab? I ahve looked at the code, seeing as Dillo already has tabs, but I just don't get C++ classes and stuff, and wouldn't know where to begin. The reason for asking this is if one has a form with a lot of data that needs processing, once submitted the data gets returned to the parent page... if there is a mistake, then you need to go back to the form, and as Dillo doesn't keep the previous page data, you have to fill it all in again. By diverting the output to a new tab, the previous parent window remains the same, ready for editing and processing again. Thanks, Nick -- Gosh that takes me back... or is it forward?

Underscores not drawn in pre with background color
by Hole.destructor＠gmx.de Aug. 17, 2016

Aug. 17, 2016

Hi Dillo developers, I stumbled upon a page with a lot of code snippets wrapped in a <pre> block, where Dillo seems to have a rendering problem: Underscores `_' are not drawn. I stripped down this real-world-example to the attached minimal html file which reproduces the problem: The page should render as follows: ============================================ softpoint_with_block() { { echo ""; } | ./softpoint.x leshouches } ============================================ However, in the development version of Dillo it renders as follows: ============================================ softpoint with block() { { echo ""; } | ./softpoint.x leshouches } ============================================ As you can see, the underscores in the function softpoint_with_block() are not drawn in Dillo. However, the underscores are drawn correcty if you * remove the style="..." specification from the <pre> block or * remove the line { echo ""; } | ./softpoint.x leshouches from the <pre> block content. Best regards, Alex

Good news in dillo's rendering!
by jcid＠dillo.org Aug. 4, 2016

Aug. 4, 2016

Hi there, Here go some good news. Originally I was to send this internally to the core devs, but as we've benefitted from the feedback of active users in the list, and their experiences with the patches (before/afterwards), on the sites they usually browse, it looks like a good idea to do it again. Since June 6, when this thread [1] was started by Sebastian, I've been investigating/working in problems related to it. This led to some extensive rendering tests that catched a laundry list of problems with our current tip (#4643 today). This is a list with brief explanations, taken from the testing data tables I've gathered so far: Problems: 1: overwrites text with images. 2: crops images (aspect ratio). 3: different layout. 4: overwrites text with text float. 5: overwrites text with text. 6: CPU HOG with: tmp.num.html, tmp.num.small.html 7: Missing page sections (sometimes works for the same page). 8: Small images cut in two sometimes ("ESP", "CRO", ...) 9: Wrong aspect ratio for images (text line height) 10: Page drawn with offset (but browser thinks other section is on screen). There're test cases for each one, and most of them were taken and reduced from real pages. Having reduced test cases is good, reduced and isolated tests is better, but the good news is that I have a couple of patches that solve all of them! I'm not saying dillo will be error-free hereafter, but that the root of a whole family of problems has been found and fixed, and this will make future testing much simpler. GROWS2 is the "Grand Redesign Of Widget Sizes" v2 by Sebastian. This is a very powerful and flexible concept whose design allows floats, layers (and absolutes in the future, and more). It has proven very fast so far, even without optimizations. Well the patches are two simple but deep changes in the way markSizeChange() and queueResize() interact. The patch idea is close to graph coverage recursions (with pruning), applied to the widget tree. I'd like to commit it, upload the test suite I'm using, and show the testing data tables I've gathered so everyone can check it with their use cases and report on it. @Sebastian: May I, or would you prefer to review them before? (the patches are the "middle ground" you mentioned. Solve the dw hog problems at dw level, not in the parser, and reuse code you've already seen. A couple of days should be enough to review) @Sebastian: Problem #10 is not related to GROWS2, but a three year old bug discovered during the tests. So let's get it done first. How to reproduce it: Go to [2], wait a bit for most images to load, then use "find text" to find the "re-re" string, scroll a bit downwards to find the image and center it. Go back then forward; no image! But dillo thinks it *is* there so move the cursor to the center of the page and you'll see the hand cursor, wait for the tooltip and drag it a bit downwards to the right. Dillo will repaint from the image data. Bisect shows the bug was introduced by #2863. Attached is a simple concept patch for it. Please review/fix/commit, as I don't know the updated invariants of resize idle. [1] http://lists.dillo.org/pipermail/dillo-dev/2016-June/010887.html [2] http://tinyurl.com/huvf6pn -- Cheers Jorge.-

ImageMagick for SVG and other image types?
by jgaffney＠lawrenceville.org July 20, 2016

July 20, 2016

At this point Dillo supports the display of GIF, PNG, and JPG, but SVG is used heavily by sites like, for example, Wikipedia. Has the Magick++ library in ImageMagick been considered for supporting these other image formats? The FLTK people seem enthusiastic about the Imago library in spite of its alpha state of development; librsvg, which looks, at least to my untutored eye, like it requires a fair amount of voodoo to use, is apparently no longer actively supported and would at any rate only provide SVG support; but ImageMagick is pretty standard with Linux distributions, and the Magick++ interface makes conversions from any format to PNG for the purposes of display extremely easy. In src/misc.c, at the end of the image part of the else-if ladder in a_Misc_get_content_type_from_data(), one could add another "rung" that uses Data and Size to create a Magick::Blob, and from this a Magick::Image, then use Magick::Image.write() to write this to another Magick::Blob of type PNG, and then replace Data and Size with those of the resulting Magick::Blob. A try-catch block would catch the cases where Data is not an image. Altogether this sort of "cheat" would require very few lines of code to implement. And the Magick++-config utility could supply the needed -D..., -I..., -l... flags to the configure script. I'm not suggesting this is an ideal long-term solution, but in the interim would at least allow the display of other image types. The most recent mention of this on the mailing list seems to be Jorge's indication on 22 April 2016 that No, there's no SVG image support in dillo yet. It should not be hard to implement though, but it needs an effort similar to GIF or PNG or JPEG code. Patch welcomed! ;) But surely someone has thought of ImageMagick before. Are there objections to using it? And if so, maybe a flag could be set by the configure script to conditionally compile this in for those who want it? (If this is pursued, the configure script should probably also check that the version of ImageMagick is recent enough to have been patched against that serious exploit in just this sort of conversion code.) A test program shows that the invocation of ImageMagick and conversions really are as simple as the steps outlined above. But I would be happy to make an attempt at a patch, if you don't mind this being undertaken by an amateur.

Problem related to generated content
by sgeerken＠dillo.org July 10, 2016

July 10, 2016

Hi! I've come upon an interesting problem. Consider this HTML (stripped down from a real world example): <head> <style> .fc:after { content: ""; display: block; clear: both; } </style> </head> <body> <div class="fc"> <div style="float: left">main</div> </div> <div style="background:#404040; color:#ffffff">footer</div> </body> Firefox (and probably other browsers) renders black text "main" on white background above white text "footer" on dark gray background. Dillo 3.0.5 does the same, for the simple reason that it does not support floats. Dillo 3.1-dev, however, renders black text "main" and white text "footer" side by side on dark gray background, because "main" is within a float. (Which is, of course, difficult to read.) The reason why Firefox renders this as it does: the definition within <style> generates something like a block element before the text containing "footer", with "clear: both" as CSS attributes; something like: <body> <div class="fc"> <div style="float: left">main</div> </div> <div style="clear:both"></div> <div style="background:#404040; color:#ffffff">footer</div> </body> Aside from the fact that dillo has still problems with this ("footer" is too much to the right; I'll investigate this independently), this shows that dillo's limited capabilities regarding generated content, together with floats, causes some unpleasing rendering errors, which are furthermore laborious to analyse (and thus not so simple to be ignored). Has someone a feasible idea to deal with this? Sebastian

URL field / Loading page images / Refreshing DNS cache
by jgaffney＠lawrenceville.org July 9, 2016

July 9, 2016

First, a huge thanks to all the Dillo team for their efforts: I just switched from 3.0.5 to the current snapshot to try out the mbedtls changes, and I am wowed not only by this, but by all the improvements in rendering, etc. Great work! A few suggestions, all very minor, that might be added to the back of the development queue: In the current snapshot, the navigation bar has changed, and the URL field does not seem to be taking into account font_factor -- with the result that the window is smaller than the font height. You can test this by setting, e.g., font_factor=2.0 in your dillorc (most dramatically for a tiny panel with small icons). The issue seems to be with this factor not being taken into account when bh and lh are set in make_panel() in ui.cc. As far as I can see, one can use the context menu to download individual images on a page, or use the panel to toggle image loading. But if one wants not to download images in general, but to download all the images for some one page (e.g., a weather forecast page), then one has to toggle downloading of images on and then off again. Maybe a command could be added to KeysCommand_t in keys.hh, bound by default to something like Ctrl-i in keys.cc, with a corresponding call to a_Html_load_images() in handle() in ui.cc? To make the switch to the current snapshot, I had, sadly, to terminate an instance of 3.0.5 that had been running continuously for 90 days without any issues. But to get that much up time it was necessary to add a little code so that SIGUSR1 would call a_Dns_freeall() and a_Dns_init(), otherwise (unless I am missing something) Dillo will persist in using the cached lookup indefinitely and not detect when the IP address has changed. So maybe some sort of key binding could be added that would flush the cache when needed? Thanks again for all your hard work!

patches #4634 and #4635
by jcid＠dillo.org July 9, 2016

July 9, 2016

Hi corvid, Some comments: ----------------- Patch #4635: rm IO flags, as they are never used Yes, those linger from a time when shutdown() was used for handling sockets in dillo. Not necessary now since we use read() write() close(). ------------------ Patch #4634: freeing http socket, close FD that's being connected Why did you do this? (i.e. Is there a specific bug?). Beware the FD is closed inside IO.c (OpEnd|OpAbort). If you close it in Http_socket_free(), you are opening race conditions on file descriptors, and coding outside the design. Http_socket_free() is used with the CCC chains, that's why it doesn't close the FD, IO will do it by means of CCC; avoiding race conditions. I haven't tested the code yet, but I'd be amazed if resources don't stop to load at random. For instance, Http_socket_reuse(int Skey) would be activating and reporting success on a socket that's just been closed. Please review all the related patches and be more careful before committing. PD: IIRC I used lsof to check for FD leaks long ago. -- Cheers Jorge.-

an experiment using mbed TLS

I wanted to see what it would take to use mbed tls with dillo. I put a copy of the diff at http://www.dillo.org/test/mbedtls.diff and I mention it here in case someone should want that one day. That said, it looks like netsurf uses curl, and curl can use any tls library you care to mention. And I'm pretty sure netsurf does javascript.

What you'd wish it had. I had been using Firefox (and still do, for trusted sites that require javascript), but looked around for another browser when the option to turn off javascript was removed from the preferences dialog -- when javascript is so often the vulnerability behind exploits, I didn't want a browser hoisting in javascript from all over the Internet at its own discretion. (It is still possible to turn javascript off in Firefox if one starts from a script that invokes a prefs.js with a legacy `user_pref("javascript.enabled", false);', or from the internal about:config page, but:) Dillo was one of the few browsers without javascript, and when I checked it out, I found that I agreed very much with Dillo's stated philosophy. And it has been my principal browser ever since. In fact, along with an xterm and Emacs, it's one of the three apps always running on my machine. Things I like about Dillo: Dillo doesn't even include javascript. (I cringe a bit when there is talk on the list about the possibility of including it -- if it is included at some point, I hope that there will be a #define to exclude that code at compile time.) Dillo is small and fast, which is nice not only for general browsing, but when invoking it through, e.g., Emacs to open a link. Dillo let's me configure things the way I like, and when it doesn't do something I want, the code base is accessible enough that I can modify it to do so. (I had in fact already implemented the suggestions I made, but didn't share any patches because, even beyond being an amateur, my hacks tend to be on the ugly side -- the loading of images per page, for example, required adding #include "html.hh" to ui.cc, indicating that I am certainly violating some logic of organization and encapsulation.) Dillo isn't phoning home or doing anything else behind my back, and it let's me easily block ad and other such sites in domainrc. Dillo doesn't try to do all sorts of exotic things, or invoke external apps to do them, with all of the potential security risks. With other browsers, you have to do a lot of work to try to prevent this sort of automagical behavior, and even if it's possible, you aren't left feeling at all confident about having prevented it. Like you, I like that Dillo caches DNS lookups, but of course IP addresses change from time to time for legitimate reasons, so there does need to be a way to flush the cache. Johannes's patch is a good one, but I also still like the idea of using the cache until I need it to refresh. Of course, one could simply start a new instance of Dillo, but I also like that it caches pages in a way that allows me to open a link to a previously visited page off-line, without trying to reconnect and reload it. And -- possibly a unique personal idiosyncrasy -- I like to see links I have visited displayed as visited. Other than that, there really isn't any reason not to be firing up a fresh instance of Dillo whenever it is needed. And probably a lot of other virtues in Dillo that just aren't coming to mind right now. > Some things may be possible, others not, a few may be solved in different > ways, etc. Just learning about those key tasks, or improving a single one, > would be a big gain for all of us. > > Your feedback as a dillo power-user is not only welcomed, it's asked for! > > >> Thanks again for all your hard work! > > Ack! > > > @all: if you're a dillo power-user, let us know about it!

CSS files downloaded only after reloading page
by Hole.destructor＠gmx.de July 8, 2016

July 8, 2016

Hi Dillo developers, the dillo version from the repository seems to have problems downloading some CSS files the first time some pages are loaded. Though, the remaining CSS files are downloaded when the page is re-loaded using CTRL-r. Example page: https://netzpolitik.org/ Reproduce: 1) dillo https://netzpolitik.org/ -> styles from some CSS files seem to be missing 2) press CTRL-r -> some new CSS file is downloaded and styles are applied 3) press CTRL-r -> some new CSS file is downloaded and styles are applied Best regards, Alex

I was just pointing out the issue; for myself, just commenting out the above line works just fine by reverting to the old behavior and smaller font size in the location bar.

CSS parser bug
by sgeerken＠dillo.org July 5, 2016

July 5, 2016

Hi! The CSS parser seems to have a bug handling shorthand properties. This example works well, both properties are handled correctly: <body style="background: url(http://www.gnu.org/graphics/heckert_gnu.small.png) repeat-y"> Adding "transparent" (for "background-color"), however, causes the other parts not to be parsed: <body style="background: transparent url(http://www.gnu.org/graphics/heckert_gnu.small.png) repeat-y"> Not a regression, dillo 3.0.5 shows the same behaviour.

trustworthiness of dillo's TLS code at present
by eocene＠gmx.com July 4, 2016

July 4, 2016

Currently I'd trust dillo for https about as much as I'd trust wget for https. (Not that I've really examined wget, but just as a sort of gauge here...) Back in the DPI days, dillo didn't check hostnames on certificates because that was an impossible nightmare with openssl unless you found the code somewhere to modify for your own project. [By the way, there was outrage a couple of years ago when people realized that lots and lots of tools out there, and tls libraries for popular languages, were using OpenSSL and not doing any hostname validation.] It was only with 3.0.5 that I had looked into TLS myself and learned enough about what's insecure at present to disable old ciphers, disable ssl3, disable tls compression. When TLS moved into the browser with the OpenSSL version, I integrated hostname checking code adapted from wget source. And now mbed TLS does the checking itself. At present, our weakness relative to something like chrome or firefox would be in the area of certificate revocation. Dillo has never had a way to know when a certificate has been revoked. For a while, there were certificate revocation lists (CRLs) that are generally published by the assorted certificate authorities, although sometimes you have to click on agreements to get them. The other problem is that those grow _huge_, and distributions don't generally have packages for them (unlike ca-certificates for root certificates). I wouldn't be surprised if the agreements bar distribution. And there was OCSP, which stands for.... Online Certificate Status Protocol. Every time you get a certificate, you query some server, often a third-party server, and ask it whether this certificate is still valid. But those OCSP servers were/are nowhere near reliable enough, and browsers couldn't very well fail everything when the OCSP servers were being flaky.. So OCSP stapling has been coming along, where the OCSP data comes from the original server along with the certificate. OpenSSL has had OCSP code for a little while, but it's very buggy and not documented, and maybe you could get it to work if your application is exceedingly similar to the sample client, but good luck. mbed TLS has OCSP on their roadmap, but it's not implemented yet. As for what the firefoxes and chromes of the world are up to, firefox ripped out their CRL code a while back and they have some other mechanism where certificate authorities notify them of revocations and they push it out. Because they're still big enough to get certificate authorities to do things for them. And they have 'public key pinning' where a server sends keys to certificates, and the client checks that, when certificates are presented in the future, they continue to use one or more of those keys. My understanding is that this is not at all widely used currently. Like if you go to google while claiming that you're chrome, maybe.

New design of tag nesting cleanup within the parser.
by jcid＠dillo.org June 24, 2016

June 24, 2016

Hi there, This is an important patchset that's just been committed. There're plenty of details in the hg comments (hg log -v). This are changes that affect the way dillo copes with Tag Soup (i.e. bad formed HTML). The idea is to create a valid doc tree before passing it to Dw for rendering, so yes, rendering may change. Please check the comments, then browse your regular sites and give it a test drive, then send some feedback. At least in my case there were nice surprises! -- Cheers Jorge.-

Strange performance behaviour related to <span>
by sgeerken＠dillo.org June 20, 2016

June 20, 2016

Hi! I've stripped down one testcase to a sequence of simple HTML snippets. Try (for i in $(seq 1 20); do echo '<div style="float:left"><div></div><div style="display:table"><span></div></div>'; done) > tmp.html; dillo tmp.html and the development version of dillo hangs for a while. You may vary the number (second argument of seq). If you look at the file tmp.html, you'll notice that it is incorrect HTML. Interrestinly, leaving the <span> away still results in incorrect and deeply nested HTML, but dillo is much faster: (for i in $(seq 1 20); do echo '<div style="float:left"><div></div><div style="display:table"></div></div>'; done) > tmp.html; dillo tmp.html Dillo 3.0.5 is fast in both cases. Does anyone have an idea what effect the <span> has? I've already run gprof, but the result does not look very meaningful at a first glance. Sebastian

Bug report - enterpress_forces_submit; mouse cursor wonky
by nick＠linicks.net June 8, 2016

June 8, 2016

Hi all, Hard one to explain. First some info; I am running: Slackware 14.1 Xfce4 4.10.0 Latest stable kernel 3.18.35 (updated today) Now, I have a word search/dictionary page with several fields, and for some reason Dillo needs to use the mouse to 'process' the submit form - I haven't investigated what can be wrong with my HTML to make Dillo just use 'enter' to 'submit' yet. I added dillorc option enterpress_forces_submit=YES and now the page 'submit' works with the enter key. But when doing so, sometimes the mouse cursor disappears altogether afterwards (but it is still there as in the WM toolbar it appears again) You can see the Dillo toolbar icons depress but no mouse. Sometimes the mouse cursor changes to a 'I' and stays like that (in Dillo). The behaviour is totally random. The page to test is here: https://linicks.net/AnAdIc/ Just use the first field to mess around in. Try 'dillo' first, then just add extra letters or other words to test (as Dillo saves the cache - we need to refresh it). Nick -- Gosh that takes me back... or is it forward?

As I recall, I was double-checking whether the textarea row attr default was still 2 in html5 (https://www.w3.org/TR/html51/sec-forms.html#the-textarea-element) searching for "rows ". But when I try this again, it doesn't crash. FWIW, I compiled with -O0. *tries valgrind* I do get a number of "Conditional jump or move depends on uninitialised value(s)" when the page loads. Searching the page doesn't cause any more, though.

"ok" for unnested body
by genoob＠yandex.com May 11, 2016

May 11, 2016

Hello! I'm a noob, so I'm sorry if this is actually not an issue, but I've searched and haven't found anything on this. When creating a simple list using `ul` (I've replaced < > with `` in order to avoid html parsing by some readers) tags I accidentally placed it after `/body``/html` and to my surprise It wasn't marked as an html error and the data was correctly displayed, jus like it would be had the list been placed inside the `html``body` `/body``/html` tags. Unnesting `li` from `ul` however displayed nesting problem, but only referring to the `li` being out of `ul` or `ol` tags, not from it being unnested from `html` `body`. I realize my explanation might be a little confusing at this point, so this is what I mean: I put it on bpaste so this message wouldn't be flagged as spam: https://bpaste.net/show/ed1374304997 And this is a screenshot of the data being displayed and getting a thumbs-up from the browser in case its relevant: http://i.imgur.com/d1f9Pv9.png I'd like to report this in case it's a bug(invalid html being marked valid), however if it's a valid html you can disregard/exclude this message from the list with no hard feelings. I'm using dillo-3.0.5-r1 by the way. I'm sorry if this was confusing and wasted your time. In case you need more info on my system I'm happy to help however I can. And thanks for maintaining such a nice project (It really helped me a lot thus far). Cheers!

Bug in meta tag refresh code [with cause]
by nick＠linicks.net May 10, 2016

May 10, 2016

I have been looking at this for about 5 hours now, and it has fried my brain. Reading the code, and then reading the email thread about depreciated meta tag 'refresh', I agree with Dillo's actions. But what I found was that on some sites (mine included), if there was a tag: <meta http-equiv="refresh" content="15" /> Dillo reports and the warning message reports: The author wanted you to go _here_ after 10 seconds. What happens now is the link (_here_) gets appended with the refresh value, so for example: www.example.com/refesh.html becomes: www.example.com/10 (or 15 or whatever the refresh value is). I have found that if the meta tag is right: <meta http-equiv="refresh" content="5;URL='./index.html'" /> then the code creates the right URL (but it's not seen as no warning is given. html.cc from line 3218 if the meta tag refresh is correct HTML on the web page, mr_url returns the correct path to the refresh. If it isn't, then mr_url returns the value of the refresh - which fubars the warning messages link. I tested this running dillo from the commandline with this insertion and testing the correct and wrong meta tags: } /* Skip to anything after "URL=" or ";" if "URL=" is not found */ if ((p = dStriAsciiStr(content, "url="))) content = p + strlen("url="); else if ((p = strstr(content, ";"))) content = p + strlen(";"); /* Handle the case of a quoted URL */ if (*content == '"' || *content == '\'') { if ((p = strchr(content + 1, *content))) mr_url = dStrndup(content + 1, p - content - 1); else mr_url = dStrdup(content + 1); } else { mr_url = dStrdup(content); } //nick printf ("%s\n", mr_url); new_url = a_Html_url_new(html, mr_url, NULL, 0); // new_url = a_Html_url_new(html, ".", NULL, 0); Not being very good with C++, I can't work out what goes wrong here - but it looks like that if 'URL=' or';' isn't found, then the code still looks for quotes - which does something to the string? I have two pages you can test on - one with the proper meta tag, and one with out: http://irpi.linicks.net:8080/static_simple.html <- good http://fishpi.linicks.net:8081/static_simple.html <- bad - that shows the bug If possible view both with that printf I put in - you can see what mr_url returns.

April 24, 2016

Hi! Since we do not have a tracking system, I suggest a new thread for every issue, with some identifier (e. g. a URL) as subject. Please focus on regressions: bugs not present in dillo 3.0.5. As for <https://www.google.com/search?ie=UTF-8&oe=UTF-8&q=dillo>, the problem are floating inline-blocks (see Johannes' posting and my answer). Floats positioned side by-side are not an issue for the next release, so I see two possibilities: 1. Leave it as it is, and start on an other positioning after the next release. 2. Deactivate inline-blocks for the next release, and re-activate as soon as side-by-side positioning of floats is implemented. This way, dillo 3.1 would render Google like 3.0.5. The latter is rather simple: diff -r 7c2e27119432 src/html.cc --- a/src/html.cc Sun Apr 24 12:21:07 2016 +0200 +++ b/src/html.cc Sun Apr 24 13:23:10 2016 +0200 @@ -4036,7 +4036,7 @@ Html_display_block(html); break; case DISPLAY_INLINE_BLOCK: - Html_display_inline_block(html); + //Html_display_inline_block(html); break; case DISPLAY_LIST_ITEM: Html_display_listitem(html); What do you think?

GROWS fixes
by sgeerken＠dillo.org April 23, 2016

April 23, 2016

Hi! After the recent changes, dillo handles 'height' specially for tables and textblocks: now, it is not possible anymore that the height of table or a textblock is less than the inherent height. This fixes - <http://forums.thinkbroadband.com> and - <https://linicks.net/AnAdIc/> (looks as with dillo 3.0.5). For tables, dillo behaves the same way as Firefox; for textblock not quite, but somewhat similar as dillo 3.0.5. This means that there is no regression, and that texblock heights may be worked on after the next release. Sebastian
