26. Local cache overview¶
While executing, cdist stores data to local cache. Currently this feature is one way only. That means that cdist does not use stored data for future runs. Anyway, those data can be used for debugging cdist, debugging types and debugging after host configuration fails.
Local cache is saved under $HOME/.cdist/cache directory, one directory entry for each host. Subdirectory path is specified by -C/--cache-path-pattern option, cache_path_pattern configuration option or by using CDIST_CACHE_PATH_PATTERN environment variable.
For more info on cache path pattern see CACHE PATH PATTERN FORMAT section in cdist man page.
26.2. Cache overview¶
As noted above each configured host has got its subdirectory in local cache. Entries in host's cache directory are as follows.
directory with cdist type emulators
dynamically determined cdist conf directory, union of all specified conf directories
directory containing global explorer named files containing explorer output after running on target host
file containing messages
directory containing subdirectory for each cdist object
object marker for this particular cdist run
directory containing init manifest and remote stderr stream output
directory containing init manifest and remote stdout stream output
file containing target host of this cdist run, as specified when running cdist
file containing types in order of execution.
26.2.1. Object cache overview¶
Each object under object directory has its own structure.
code generated from gencode-local, present only if something is generated
code generated from gencode-remote, present only if something is generated
directory containing type explorer named files containing explorer output after running on target host
directory with object files created during type execution
directory containing type parameter named files containing parameter values
this type's source (init manifest)
this type execution state ('done' when finished)
directory containing type's manifest, gencode-* and code-* stderr stream outputs
this type stdin content
directory containing type's manifest, gencode-* and code-* stdout stream outputs.
