Thunderbird should support setting itself as the default mail and/or news client for GNOME, as it does on Windows.

This implements some code very similar to nsGNOMEShellService in Firefox, except that it conforms to nsIMapiRegistry... which, despite the name, is fairly generic. One thing I decided not to support is _un_setting Thunderbird as the default mail/news client. There are plenty of other ways a user can do that, and I don't think we are obligated to include it in our UI. mscott tells me we do need to on Windows because we install our own MAPI dll and need to restore the original one when we no longer want to be the default. There's no similar situation on GNOME, so I changed the UI to be more like what Firefox has. By default it prompts for being the default mail client; you have to go specifically tell it to be the default news client since that's less common. If it turns out we want to have it offer to be the default news client by default, I'll either need to roll it into an all-or-nothing setting or combine them into one dialog (throwing up _two_ dialogs about it on startup would suck). This includes a port of the start script changes that Firefox got recently to better handle communicating with a running instance. The only difference is that if you don't give a URL to load I call openInbox rather than openBrowser. Also, to avoid adding yet another shared library, I merged this with the migration module.

Comment on attachment 153628 [details] [diff] [review] patch (new files are first, diffed separately) I'm not sure what these macros are supposed to do: NS_HIDDEN_ I'm assuming it's a unix build thing and trust your judgement. I see you added a new mail\components\build directory and moved some stuff out of mail\migration\src. The module registration for the migration stuff has changed quite a bit on the branch and the trunk in the last week or so. Make sure your removal of that stuff is up to date so we don't lose any module registration info for migration. Thanks again for doing this Brian. With these changes, can I now obsolete: http://www.mozilla.org/projects/thunderbird/linuxurls.html with the next release?

Whould be cool to see this checked in. Any plans?

checked in on trunk and aviary branch.

messenger-mapi needs to be added to en-US-jar.mn for the US -> en-US jar move.

This doesn't seem to work in the trunk and aviary Linux builds from 20040729. (Is this the point that comment 4 is making?) Neither sets the default app, and both give the following JavaScript error when "Check Now" is pressed: Error: uncaught exception: [Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIStringBundle.formatStringFromName]" nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)" location: "JS frame :: XStringBundle :: getFormattedString :: line 33" data: no] I'm running RedHat Linux 9 with GNOME 2.2.

Re my comment 6, Aviary 20040730 seems okay.

*** Bug 242255 has been marked as a duplicate of this bug. ***

Has this caused regression bug 253475? The checkins to mozilla/mailnews are affecting MailNews, right? It seems that the locale for messenger-mapi was moved from en-win.jar to en-US.jar, but none of the packaging or installer files were changed for windows to reflect that (like in Bug 253617).

This broke installer builds because they're still looking in en-win for the mapi locale.

this has been working nicely; vrfy'ing fixed with recent aviary1.0 tbird builds on linux fc2.
