This this a Firefox bug? Does look like it can be worked around (in both Chrome and Firefox) by keeping # as # in the URL: This works in both browsers: http://golang.org/doc/play/#package%20main%0Afunc%20main()%20%7B%0A%09println(%22#%22)%0A%7D%0A |
# is not the problem; % is. This URL: http://golang.org/doc/play/#package%20main%0Afunc%20main()%20%7B%0A%09println(%22%25%22)%0A%7D%0A works in Chrome, not in Firefox. |
A workaround for anyone also having the problem with FF. Not nice, just works. http://golang.org/doc/play/#package%20main%0Afunc%20main%28%29%20{%0A%09println%28%22\x25%22%29%0A}%0A BTW: If there is some way for me to help with solving this issue, I'l be happy to volunteer. |

Comment 7 by disposaboy@dby.me: Unfortunately this is an issue(probably a bug in at least Gecko based browsers) with the behaviour of decodeURIComponent in that it appears to decodes %25 then borks at the possibly unexpected % sign. I don't have IE handy to test (and I have no reason to expect it to break there) but a possible workaround is to just use escape/unescape as opposed to encodeURIComponent/decodeURIComponent. AFAICT that pair simply works. |
// Called directly by OS as signal handler. #pragma textflag 7 before the definition of runtime.sigignore in both freebsd/386/signal.c and freebsd/amd64/signal.c. This is a difference compared to the Darwin port because on Darwin the function gets called via sigtramp. On FreeBSD it is being given to the signal handler directly, so it cannot be a typical Go stack-checking function. |
I found the error. It is indeed a bug in Firefox when retrieving the hash through
window.location.hash.
I found a cross-platform solution for the same purpose.
So to fix the issue, we need to replace line 163 in playground.js by the following :
var hash = location.href.split("#")[1] || "";

Before filing a bug, please check whether it has been fixed since the latest release: run "hg pull -u" and retry what you did to reproduce the problem. Thanks. N/A What steps will reproduce the problem? 1. Using Firefox 3.6.17 [Mozilla/5.0 (X11; U; Linux x86_64; cs-CZ; rv:1.9.2.17) Gecko/20110422 Ubuntu/10.04 (lucid) Firefox/3.6.17] visit golang.org. 2. Enter into the playground's text area: package main func main() { println("%") } 3. Verify it's OK by clicking the "COMPILE & RUN" button (or shift-enter). 4. The single percent sign is seen as the correct output of the above program. 5. Click the "Pop Out" link bellow the input yellow text area. What is the expected output? A new window with the program as in step 2. What do you see instead? A new window with the "Hello World" example. Which compiler are you using (5g, 6g, 8g, gccgo)? N/A Which operating system are you using? See details in step 1. Which revision are you using? (hg identify) N/A Please provide any additional information below. Doing all the same while replacing the percent sign with e.g. a hash sign (#) works as expected. The problem seems to be related with the value %25 in the escaped URL in the pop out window. Additionally, everything works (both with % and with #) OK in a Chrome browser [11.0.696.57 beta]. Other browsers were not tested.The text was updated successfully, but these errors were encountered:
