Where does OSX keep them? I'd looked on the web a bit in the past in case there was any simple consensus out there on the matter of where to check, but didn't find anything. I'll see where curl checks. Whatever they do is probably a good idea.

can't access http://www.dillo.org/index.html after pushing an update to it :( :(

Forbidden You don't have permission to access /index.html on this server. :( (I added some mention of 3.1 and 3.0.4.1 for clarification after noticing that our ChangeLog link only shows 3.0.4.1 at the moment.) I had this happen with another file some weeks ago, and I mentioned it to Andreas, who either fixed it or it resolved on its own somehow. I don't believe I've changed anything. My umask is 0066, but that's not new at all.

--local, reload, repush

BTW, when I was checking --local, I noticed that it will start to request images and stuff upon reload as expected, but then when there's a repush, SpamSafe is on again.

what's currently broken in dillo
by eocene＠gmx.com 27 Nov '14

27 Nov '14

Since fltk had a release today, I was thinking about where dillo stands at present. Here are the problems that I can think of: - vsource request crashes when dpid isn't working. - source is slow to render, presumably something to do with large tables. - on some sites, rendering never stops as the horizontal scrollbar shows the page growing wider and wider. - on some sites, the ending words of a line are missing. - text search while loading, assert failed. - img alt text not constrained by width/height.

Todo "dpid_idle_timeout variable to dpidrc" and config parsing generally
by james.from.wellington＠gmail.com 21 Nov '14

21 Nov '14

Hello all, In dpid/dpid.c at about line 204, there is a todo, that dpid_idle_timeout should be configurable. I looked at how to do this sympathetically with the existing code and blocked, because the configuration file is: - having its location calculated - being opened - being scanned into heap memory several times in the existing code. My over-response is to write a library to: - private memory-map it - parse it into a linked-list in the comments in the file and - have everyone who traversed the file now traverse the linked-list On the way, we get new functionality: - the ability to record the use of a configuration item - the ability to report on unused configuration items -- which are interesting because they're probably typos Parsing dillorc with the default options uncommented, this approach is about 4* faster than the existing approach. I think that it will also have a smaller VM footprint, because we are already paying for cooked disk buffers for the same amount of file, more times. The diff is 1400 lines, so I don't expect instant rejoicing :-) The attached file contains my test-cases, shell scripts to generate some of them, that are tricky, and the diff which inserts the code into revision b185e43. Regards, James.

Strange linebreaking when long hyphenated words appear in table cells
by onepoint＠starurchin.org 19 Nov '14

19 Nov '14

The attached file demonstrates the problem. The test in the first paragraph easily linebreaks to fit the width of the window because of the potential linebreaks after each hyphen. The same text inside of a table cell forces the cell to be almost as wide as the unbroken text, although some line breaking does happen. My guess is that Dillo calculates the minimum width of the table cell without accounting for potential linebreaks after hyphens in the text. However, when it later fills the cell with the text it does allow linebreaks after hyphens. If that is correct then I think Dillo should account for potential linebreaks after hyphens both when calculating the minimum width of the cell and when filling the cell with text. The current situation is inconsistent and can deliver very poor results. Regards, Jeremy Henty

What's the repository for latest dillo?
by waltdnes＠waltdnes.org 17 Nov '14

17 Nov '14

I've got dillo-3.0.4 running on Gentoo linux, with fltk-1.3.2. People here seem to be running experimental "bleeding edge" versions. I assume it's from a git repo. What are the instructions to download and build dillo, preferably in my user directory? I'm aware that it may be broken on edge cases. I'm not a C programmer. My main skills are in bash shell scripting. If nothing else, I'll be another tester. -- Walter Dnes <waltdnes at waltdnes.org>
