ELinks built from "master" branch crash #329

Open SchweinDeBurg opened 3 weeks ago

SchweinDeBurg commented 3 weeks ago

I've just packaged ELinks from "master" branch (commit [ecmascript] Fix location.reload) and installed it. Opened the terminal and entered elinks https://kernel.org/. ELinks then shows the following output: 2024-09-21_18-37 I've pressed Ctrl+L and then everything looks fine: 2024-09-21_18-38 But when I've tried to press Down key ELinks crashed:

I've attached my RPM-spec file where are you can see my ELinks configuration, libraries versions, and so on: elinks-0.17.0-fedora.spec.gz

rkd77 commented 3 weeks ago

Yes, js in elinks is not ready yet. I'll build elinks from this spec, when libdom-devel appears in rawhide.

SchweinDeBurg commented 3 weeks ago

Hm-m-m... I've packaged libdom by myself because https://pkgs.org/ doesn't show me this library in any Fedora version. Is https://www.netsurf-browser.org/projects/libdom/ the right source?

SchweinDeBurg commented 3 weeks ago

Good news! I've just repackaged libdom from its HEAD, then rebuilt ELinks from commit [select] Do not kill timer in case of (curl,select) combination -- and now Down key problem goes away, thank You so much for the point! But the problem from the first screenshot is still there.

rkd77 commented 3 weeks ago

Weird, does grep -r on sources find any "AFTER_BODY" or similar text ?

SchweinDeBurg commented 3 weeks ago

I've searched these strings just yesterday and it looks like these strings are coming from mozjs library because parser/html/nsHtml5TreeBuilder.h contains int32_t constants named exactly the same. Probably there is a magic macro somewhere in Mozilla codebase which converts these names to string literals.

rkd77 commented 3 weeks ago

-Dfastmem=true disables assertions, so I would check this.
