Subject: [PATCH] job: avoid recursion into transaction code from job
|
|
cancelation
|
|
|
|
I hit an "assert(j->installed)" failure in transaction_apply(). Looking
|
|
into the backtrace I saw what happened:
|
|
1. The system was booting. var.mount/start was an installed job.
|
|
2. I pressed Ctrl+Alt+Del.
|
|
3. reboot.target was going to be isolated.
|
|
4. transaction_apply() proceeded to install a var.mount/stop job.
|
|
5. job_install() canceled the conflicting start job.
|
|
6. Depending jobs ended recursively with JOB_DEPENDENCY, among them was
|
|
local-fs.target/start.
|
|
7. Its OnFailure action triggered - emergency.target was now going to be
|
|
isolated.
|
|
8. We recursed back into transaction_apply() where the half-installed
|
|
var.mount/stop job confused us.
|
|
|
|
Recursing from job installation back into the transaction code cannot be
|
|
a good idea. Avoid the problem by canceling the conflicting job
|
|
non-recursively in job_install(). I don't think we'll miss anything by
|
|
not recursing here. After all, we are called from transaction_apply().
|
|
We will not be installing just this one job, but all jobs from a
|
|
transaction. All requirement dependencies will be included in it and
|
|
will be installed separately. Every transaction job will get a chance
|
|
to cancel its own conflicting installed job.
