- service: serialize information about currently executing command
-
- Stored information will help us to resume execution after the
- daemon-reload.
-
- This commit implements following scheme,
-
- * On serialization:
- - we count rank of the currently executing command
- - we store command type, its rank and command line arguments
-
- * On deserialization:
- - configuration is parsed and loaded
- - we deserialize stored data, command type, rank and arguments
- - we look at the given rank in the list and if command there has same
- arguments then we restore execution at that point
- - otherwise we search respective command list and we look for command
- that has the same arguments
- - if both methods fail we do not do not resume execution at all
-
- To better illustrate how does above scheme works, please consider
- following cases (<<< denotes position where we resume execution after reload)
-
- ; Original unit file
- [Service]
- ExecStart=/bin/true <<<
- ExecStart=/bin/false
-
- ; Swapped commands
- ; Second command is not going to be executed
- [Service]
- ExecStart=/bin/false
- ExecStart=/bin/true <<<
-
- ; Commands added before
- ; Same commands are problematic and execution could be restarted at wrong place
- [Service]
- ExecStart=/bin/foo
- ExecStart=/bin/bar
- ExecStart=/bin/true <<<
- ExecStart=/bin/false
-
- ; Commands added after
- ; Same commands are not an issue in this case
- [Service]
- ExecStart=/bin/true <<<
- ExecStart=/bin/false
- ExecStart=/bin/foo
- ExecStart=/bin/bar
-
- ; New commands interleaved with old commands
- ; Some new commands will be executed while others won't
- ExecStart=/bin/foo
- ExecStart=/bin/true <<<
- ExecStart=/bin/bar
- ExecStart=/bin/false
-
- As you can see, above scheme has some drawbacks. However, in most
- cases (we assume that in most common case unit file command list is not
- changed while some other command is running for the same unit) it
- should cause that systemd does the right thing, which is restoring
- execution exactly at the point we were before daemon-reload.
-
- Fixes #518
