8549 - component.reg needs to be writeable for apprunner to start

Status: VERIFIED DUPLICATE of bug 9120

(Core :: XPCOM, defect, P3)

Description

[tor]

Description:

apprunner opens component.reg O_RDWR, which will fail if the mozilla
installation directory is on a read-only filesystem.  Will probably
also fail to run on a read-write filesystem if someone other than
the installer tries to run apprunner.

Steps to reproduce:

Copy dist/bin to a read-only filesystem, then run apprunner.

Actual results:

apprunner quietly dies after spitting out these messages:

	Registered Ok
	*** Registering html library

Expected results:

apprunner starting normally.

Build date & platform:

6/19/99 build on Solaris

Additional information:

% truss ./apprunner | & fgrep component.reg
open64("/cs/lib/mozilla/component.reg", O_RDWR|O_CREAT, 0644) Err#30 EROFS
open64("/cs/lib/mozilla/component.reg", O_RDWR|O_CREAT, 0644) Err#30 EROFS
open64("/cs/lib/mozilla/component.reg", O_RDWR|O_CREAT, 0644) Err#30 EROFS
open64("/cs/lib/mozilla/component.reg", O_RDWR|O_CREAT, 0644) Err#30 EROFS

This is true. The first time you run apprunner, component.reg will be written
to. The hope is that this is equivalent to the installation step and once we
have an installer would go away.

On subsequent runs, components.reg should be READONLY. And should be opened so.
The fact that it always open for RDWR is a bug.

[bugday] This bug deals with the same file that the other does.
