182678 – replaceState cause back/forward malfunction on html page with <base href="/"> tag

huocp

Reported 2018-02-11 14:54:32 PST

To reproduce the issue. 1. create an static index.html file with following content <!doctype html> <html> <head> <title>test</title> <base href="/"> </head> <body> </body> 2. serve the file with same http server, for instance use nodejs http-server (npm install -g http-server) 3. use Safari to open the local site. (in Safari preference, turn on "Show full website address" in advanced tab) 4. in Safari dev console, do following line by line history.pushState({}, "", "/one"); // browser shows url "/one", as expected. history.replaceState({}, ""); // 3rd param is optional new url, we leave it out to not override it. history.pushState({}, "", "/two"); // browser shows url "/two", as expected. history.back(); // browser shows url "" instead of "/one". This is the bug! This bug only appears on webpage with `<base href="/some_base">` tag. This bug appears on latest macOS Safari 11.0.3, latest iOS Safari 11, latest macOS Safari Technology Preview release 49. I did not test on any older version of Safari. As a reference, this bug doesn't affect Chrome or Firefox. To bypass this bug, I need to feed current url back to replaceState. history.replaceState({}, "", "/one"); // bypass the bug.

The message should still make it clear if it is a PASS or a FAIL. Otherwise, someone may just rebaseline the test if it starts printing out a different URL.

It's very important for each test to make it clear whether something is passing or failing. I wish we were more disciplined about this throughout our project.

Please take a look. Note that the answer might be that the test was actually broken, we didn't realize it, and this patch fixes it. In which case we just need new expectations. (I can't verify this theory myself because I can't see what the failure is/was)
