Jobs can be created with user-provided IDs containing any character
except spaces. The jobId needs to be escaped when used in a request
path, otherwise jobs created with names such as "why?" can't be managed
after they are created.
Given that the values will rarely change, specially considering that any
changes would be backward incompatible change. As such, it's simpler to
keep syncing manually in the rare occasion and avoid the syncing code
overhead.
Embed pointer conversion functions in the API package to avoid
unnecessary package dependency. `helper` package imports more
dependencies relevant for internal use (e.g. `hcl`).
nomad/structs is an internal package and imports many libraries (e.g.
raft, codec) that are not relevant to api clients, and may cause
unnecessary dependency pain (e.g. `github.com/ugorji/go/codec`
version is very old now).
Here, we add a code generator that imports the relevant constants from
`nomad/structs`.
I considered using this approach for other structs, but didn't find a
quick viable way to reduce duplication. `nomad/structs` use values as
struct fields (e.g. `string`), while `api` uses value pointer (e.g.
`*string`) instead. Also, sometimes, `api` structs contain deprecated
fields or additional documentation, so simple copy-paste doesn't work.
For these reasons, I opt to keep the status quo.
The parse endpoint accepts a hcl jobspec body within a json object
and returns the parsed json object for the job. This allows users to
register jobs with the nomad json api without specifically needing
a nomad binary to parse their hcl encoded jobspec file.
This PR fixes an issue in which we would merge an update stanza from the
job into the task groups even if it was empty. This broke round
tripping a job (reading from the api and resubmitting as JSON)
