[Tracker] doesn't open several selected files if folder doesn't contain subfolder

[diver]

Race condition in BRoster::Launch(): Two processes launching the same app at the same time. If the second one preempts the first one before it has finished the early pre-registration with the registrar it doesn't get a valid team ID and fails to send its "on launch" messages (argv, refs). Reproducible using the Tracker: open several text files at once (with the editor not yet running).

While I can easily reproduce the problem itself (that Tracker doesn't open all of the selected files), I fail to see any connection with having a folder in that directory or not. It only works flawlessly when the application is already running. I would assume this to be a bug in libbe.so.

Files in /boot/beos/system/boot are executeable shell scripts, not normal text files. None should be opened (in text editor?), they all should be executed.

I've investigated the issue, and it's the fault of the Registrar. Tracker just does several BRoster::Launch() in a row. The first BRoster::_AddApplication() will succeed, the subsequent ones will fail with B_ALREADY_RUNNING - unfortunately, BRoster::GetRunningAppInfo() will fail afterwards, as the team hasn't completed its registration. Therefore, the messages are not sent to the application. If we also use GetAppInfo(signature, ...) the message will be sent, but still doesn't reach the team, as it doesn't have completed its registration, and therefore its team variable is still unset (which the registrar obviously doesn't care about too much). Either the team value has to be set earlier (as part of the preregistration), or the registrar needs to collect messages targeted at such a team and send them when it completes its registration. I'll give Ingo a try at a better solution ;-)

To Marcus: none of them has the executable bit set, furthermore, only the installer scripts have the bash shebang.
