Swift configuration parameter audit
This change is the result of an audit through the config parameters
provided by swift and how/if they are addressed in the swift
documentation. The documentation being the sample config files in
the /etc directory or the documentation.
This change is only concerned with the config files in etc/ next
I will look at the documentation in the doc/ folder.
This change makes the following assumptions:
- Unless stated otherwise, the commented out parameter in the
sample configuration is the default for swift.
- When the default in the code differs from that of the sample
configuration, the default in the code is correct.
Container reconciler:
Parameter: interval
- code: 30
- config: 300
Result: config = 30
Object Expirer:
Parameter: recon_cache_path
- code: /var/cache/swift
- config: Parameter missing
Result: Add parameter
swift-dispersion-populate && swift-dispersion-report
Parameter: auth_version
- code: 1.0
- config: 2.0 (due to being a confusing example of how to setup
version 2.0).
Result: Added 'auth_version = 1.0' to the right section (showing
default and make the sample configuration for auth version
2.0 easier to understand.
swift-drive-audit:
Parameter: log_file_pattern
- code: /var/log/kern.*[!.][!g][!z]
- config: /var/log/kern*
Result: config = /var/log/kern.*[!.][!g][!z]
NOTE: swift-drive-audit uses a parameter called device_dir which
defaults to '/srv/node'. In all other swift binaries/services
there is a similar parameter called devices which stores the
same thing. This is an inconsistency which I haven't fixed
as this could break existing swift clusters out in the wild.
Proxy Server:
Parameter: object_chunk_size
- code: 65536
- config: 8192
Result: config = 65536
Parameter: client_chunk_size
- code: 65536
- config: 8192
Result: config = 65536
Parameter: strict_cors_mode
- code: True
- config: No parameter
Result: config = True
Account and Container replicator configuration confusion:
NOTES:
The account and container replicators have parameters:
- interval
- run_pause
Both of these are loaded into the same variable in code:
self.interval = int(conf.get('interval') or
conf.get('run_pause') or 30)
If a user sets both to different values then interval is used.
Result: Update the configuration to make this more clear.
