238830 - Double-clicking .xul file leads to "c: Protocol not registered"

Status: NEW

(SeaMonkey :: UI Design, defect)

Description

[Christian :Biesinger (don't email me, ping me on IRC)]

[cc'ing some people who may be interested in fixing this, and bsmedberg who
commented on this on irc]

double clicking an xul file in explorer shows me that the c: protocol is not
registered. that's because mozilla is launched with something like -chrome
"c:\foo\bar.xul", which is a filepath, not a url.

somewhat hackish workaround: change the registry
(HKCR\MozillaXUL\shell\open\command, Default Value) to use -chromne
"file:///%1", which works.
alternative may be to make the chrome argument handler support  filepaths in
addition to urls.

(In reply to comment #0):
.xul files are opened with the commandline:
X:\PATH\TO\MOZILLA.EXE -chrome "%1"

After looking at the relevant code, i'll repeat here what I said on IRC.

I am going to bow out of programming mozilla until I have a *much* better
understanding of XPCOM, OOP and C++.

Adios, people.

Notes:
The -url handler must do fixup on the url at some point, because it will accept
all sorts of junk e.g. ftp.mozilla.org
The -chrome handler is also used for the chrome: protocol shortcut handler,
which will feed it URLs.

jhermans, can you please not mark seamonkey bugs as duplicate of firefox bugs.
also, consider duping the higher-numbered bug to the lower-numbered one rather
than the other way round, unless the newer one has more information/patch/...

this one is probably not a duplicate either way.

note Seamonkey uses winhooks, Firefox uses nsIShellService and friends.

The same happens to Thunderbird if I double click an external eml file.

Comment 9

Detail on the message above:
It ONLY happens if Thunderbird is closed and it has to awake because you double clcked on a ".eml" file.

If Thunderbird is open, NO ERROR occurs.

The actual message translate to English is: "c: is not a registered protocol"
