2012-04-24service: introduce Type=idle and use it for gettysLennart Poettering
Type=idle is much like Type=simple, however between the fork() and the exec() in the child we wait until PID 1 informs us that no jobs are left. This is mostly a cosmetic fix to make gettys appear only after all boot output is finished and complete. Note that this does not impact the normal job logic as we do not delay the completion of any jobs. We just delay the invocation of the actual binary, and only for services that otherwise would be of Type=simple.
2012-04-24manager: drop MountAuto= and SwapAuto= optionsLennart Poettering
The ability to set MountAuto=no and SwapAuto=no was useful during the adoption phase of systemd, so that distributions could stick to their classic mount scripts a bit longer. It is about time to get rid of it now.

2012-04-23transaction: cancel jobs non-recursively on isolateMichal Schmidt
Recursive cancellation of jobs would trigger OnFailure actions of dependent jobs. This is not desirable when isolating. Fixes https://bugzilla.redhat.com/show_bug.cgi?id=798328
2012-04-24job: serialize jobs properlyMichal Schmidt
Jobs were not preserved correctly over a daemon-reload operation. A systemctl process waiting for a job completion received a job removal signal. The job itself changed its id. The job timeout started ticking all over again. This fixes the deficiencies.
2012-04-24transaction: abort does not need to use recursive deletionMichal Schmidt
Recursion is unnecessary, because we're deleting all transaction jobs anyway. And the recursive deletion produces debug messages that are pointless in transaction abort.
2012-04-24transaction: fix detection of cycles involving installed jobsMichal Schmidt
A transaction can be acyclic, but when it's added to installed jobs, a cycle may result. transaction_verify_order_one() attempts to detect these cases, but it fails because the installed jobs often have the exact generation number that makes them look as if they were walked already. Fix it by resetting the generation numbers of all installed jobs before detecting cycles. An alternative fix could be to add the generation counter to the Manager and use it instead of starting always from 1 in transaction_activate(). But I prefer not having to worry about it wrapping around.
2012-04-24transaction: improve readabilityMichal Schmidt
The functions looked complicated with the nested loops with breaks, continues, and "while (again)". Here using goto actually makes them easier to understand. Also correcting the comment about redundant jobs.

2012-04-20transaction: add starting requirements for JOB_RESTARTMichal Schmidt
While having a Requires= dependency between units, the dependency is started automatically on "systemctl start", but it's not started on "systemctl restart". JOB_RESTART jobs did not pull the dependencies for starting into the transaction. https://bugzilla.redhat.com/show_bug.cgi?id=802770 Note that the other bug noted in comment #2 has been fixed already by avoiding the deletion of anchor jobs.
2012-04-20dbus-job: allow multiple bus clientsMichal Schmidt
Merging of jobs can result in more than one client being interested in a job.
2012-04-20transaction: remove checks for installedMichal Schmidt
Transactions cannot contain installed jobs anymore. Remove the now pointless checks.
2012-04-20transaction: rework merging with installed jobsMichal Schmidt
Previously transactions could reference installed jobs. It made some issues difficult to fix. This sets new rules for jobs: A job cannot be both a member of a transaction and installed. When jobs are created, they are linked to a transaction. The whole transaction is constructed (with merging of jobs within, etc.). When it's complete, all the jobs are unlinked from it one by one and let to install themselves. It is during the installation when merging with previously installed jobs (from older transactions) is contemplated. Merging with installed jobs has different rules than merging within a transaction: - An installed conflicting job gets cancelled. It cannot be simply deleted, because someone might be waiting for its completion on DBus. - An installed, but still waiting, job can be safely merged into. - An installed and running job can be tricky. For some job types it is safe to just merge. For the other types we merge anyway, but put the job back into JOB_WAITING to allow it to run again. This may be suboptimal, but it is not currently possible to have more than one installed job for a unit. Note this also fixes a bug where the anchor job could be deleted during merging within the transaction.
2012-04-20job: separate job_install()Michal Schmidt
Let the jobs install themselves.
2012-04-20transaction: remove a couple of assertsMichal Schmidt
We already asserted these facts in the previous loop.
2012-04-20transaction: remove the anchor linkMichal Schmidt
tr->anchor_job is sufficient.
2012-04-20transaction: avoid garbage collecting the anchor jobMichal Schmidt
Make sure the anchor job is never considered garbage, even if it has no links leading to it (this will be allowed in the next patch).
2012-04-20transaction: simplify transaction_find_jobs_that_matter_to_anchor()Michal Schmidt
2012-04-20transaction: change the linking of isolate jobs to the anchorMichal Schmidt
When isolating, the JOB_STOP jobs have no parent job, so they are all peers of the real anchor job. This is a bit odd. Link them from the anchor job.
2012-04-20transaction: maintain anchor_jobMichal Schmidt
Track which job is the anchor in the transaction.
2012-04-20transaction: do not add installed jobs to the transactionMichal Schmidt
Do not attempt to optimize away the job creation by refering to installed jobs. We do not want to disturb installed jobs until commiting the transaction. (A later patch to job merging will make the separation of transaction jobs and installed jobs complete.)
2012-04-20job: jobs shouldn't need to know about transaction anchorsMichal Schmidt
Let the transactions maintain their own anchor links.
2012-04-20job: job_new() can find the manager from the unitMichal Schmidt
2012-04-20manager: split transaction.[ch]Michal Schmidt
manager.c takes care of the main loop, unit management, signal handling, ... transaction.c computes transactions. After split: manager.c: 65 KB transaction.c: 40 KB
