139185 - siga.ufrj.br - requires IE 6

Status: RESOLVED FIXED

(Tech Evangelism Graveyard :: Portuguese, defect)

Description

[Cesar Eduardo Barros]

The new SIGA system UFRJ developed (used to check your grades, amongst other
things) only works in IE 6. Faking the user-agent doesn't make it work either,
so they are probably using some broken JavaScript. The system is acessible to
all UFRJ students and teachers (you need a password to get in. The logon screen
is at www.ufrj.br).

I will attach some screenshots of the site.

This is what I sent to the webmaster using the feedback form:

Porque fazer um sistema que só funciona no IE6? Muita gente não tem esse
browser. E os usuários de Unix (como eu), como é que fica? O Netscape 6 tem um
JavaScript parecido com o do IE6 (incluindo DOM). Não deve dar muito trabalho
suportá-lo (comparado com a dificuldade de suportar o Netscape 4).

Os browsers que eu tenho são IE5 (nunca usei; o IE tem muitos furos de
segurança, vide http://jscript.dk/unpatched/), Netscape 4.7, Netscape 6.0, e
Mozilla 1.0RC1 (mesmo código do Netscape 6; mais próximo do Netscape 6.2), que é
o que eu uso normalmente.

Não tenho espaço em disco na partição com Windows 98 para instalar o IE 6 (a
partição é muito pequena, uma vez que só uso para fazer o imposto de renda; todo
o resto eu faço no Linux). Além disso, há o risco de a instalação do IE 6 causar
problemas (uma vez que ela altera parte do sistema operacional).

Vou tentar ir ao laboratório do DCC (quase uma hora de ônibus, uma vez que moro
em Niterói) e acessar de lá. Embora eu ache difícil, pois pelo que eu me lembro
ele tem uma versão bem antiga do Netscape 4 (no laboratório Linux) e várias
variações de IE 5 e IE 5.5 (no laboratório Windows), metade das quais trava ao
acessar qualquer página https.

They've invited me to help. I'm waiting for their reply. If I get in, I think
I'll assign this bug to myself.

Open the JavaScript console under Tools and see if any error appear for that site.

Yes.

I believe at least browser.js can be downloaded without any passwords (the
authentication seems to be cookie-based and only in the .jsp pages)

So, it looks like it's document.all that is the problem (that was the
information you were looking for, right?)

Assigning to myself. I'm working with them on it.

Comment 8

[Cesar Eduardo Barros]

Really accepting this time

Comment 9

[Cesar Eduardo Barros]

Looks like I can't accept my own bug, even if it's one of the options when I'm
logged in... :(

[Katsuhiko Momoi]

Confirming the bug, re-assigning to Cesar and CC'ing Marcio. 
The site seems to be using sniffing script to put up a dialog.
I tried this with the current 1.0 branch build and I am not 
getting the kind of errors Cesar is. 
Marcio, please take a look and confirm the problem if 
possible.

momoi, you can't get the error messages without having a password. If you
somehow manage to get in without one (and I'm not talking about the .js files),
that's a bug in the site. You also need to fake the user-agent (looks like
server-side sniffing, but I'm not 100% sure).

The bug is still unconfirmed; bugzilla seems to be acting screwy... (at least
you managed to reassign)

Comment 12

[Brant Gurganus]

Confirming per comment #10.  Also updating platform and OS since this will
happen on all platforms and OSs since document.all is proprietary

[Kai Lahmann (is there, where MNG is)]

looks better now - or?

Nobody announced it, it still says it needs IE 6, but if you try to go there
with Mozilla, it will work (except in some functions which probably haven't been
converted yet). Closing.
