Segfault on sites requiring authentication

by tim.nieradzik＠gmx.de

Whenever I visit http://puppyisos.org/isos (puppy / linux), Dillo segfaults. The reason is that in some cases the variable Client_bw is NULL. However, some functions depend on it and access its member variables. Client_bw is initialized in Cache_process_queue() (src/cache.c). When authentication is required, this variable is passed over to Cache_auth_entry() which sets a timeout. Its callback (Cache_auth_callback()) opens up a dialog asking for the credentials and then calls a_Nav_reload() with the Client_bw as its first parameter. Finally in a_Nav_cancel_expect() Client_bw's member variable nav_expecting is used and as bw is NULL, Dillo segfaults. I came up with a small patch that removes Cache_auth_callback() and Cache_auth_entry() as I have not seen any advantages in delaying the authentication popup. The next thing I did was to show the dialog on condition that Client_bw is not NULL and that we have finished the transfer (At least I hope CA_Close is the proper flag for doing so). There were various unnecessary checks in src/nav.c. They compared bw with NULL. In my opinion the affected functions (a_Nav_expect_done, a_Nav_push and a_Nav_repush) should never be called if you cannot be sure that bw is not NUL. What is your view on this subject? Unfortunately, my approach does not solve the original problem that caused Client_bw being NULL. Furthermore, the patch introduces a new bug: The dialog pops up when reloading the site but after having entered the correct credentials or having pressed the ``Cancel'' button, it appears again. Any ideas? While digging deeper into the code, I noticed that we make heavy use of timers for popups and reloading pages? Is there any special reason for it? --Tim

All right, then I can either call it "Browser tools" in the tooltip or be careful always to call it the tools/settings button in documentation.

The tooltips explain briefly what each button does. In this case it could also be: "Browser settings", "Customize browser behaviour", "Browser tools", "Browser preferences" or similar. I'd keep "Tools" as the name of the button and try to find a good tooltip text. Comments/Suggestions/Other_ideas? -- Cheers Jorge.-

tools button name (a very trivial matter)

by corvid＠lavabit.com

I was going to update the dillorc comment for load_images (still mentions the old dedicated button), and... to developers, it's in the Tools button's menu now, but to users, it's the Settings button because that's what the tooltip says. We should standardize on one name or the other.

memory use

A while ago, I noticed that dillo was using a lot of memory on a specific page, and I didn't remember it doing that before. So I tested a few versions and found that dillo2 uses more memory initially, but less memory for large tables. Specifically: Memory use (in KiB) (on ubuntu 7.10 x86_64) dillo-0.8.6/src/dillo: 3692 file:///nothing 4900 http://dillo.org/ 45204 http://idlerpg.net/db.php dillo-2.0/src/dillo: 4700 file:///nothing 6564 http://dillo.org/ 36408 http://idlerpg.net/db.php hg/dillo/src/dillo: 4812 file:///nothing 6684 http://dillo.org/ 36756 http://idlerpg.net/db.php > Note: I remmeber having an awful memory footprint on 64bit > Ubuntu.
