* Make the script scraper context-aware
Connect the context to the command execution. This means command
execution can be aborted if the context is canceled. The context is
usually bound to user-interaction, i.e., a scraper operation issued
by the user. Hence, it seems correct to abort a command if the user
aborts.
* Enable errchkjson
Some json marshal calls are *safe* in that they can never fail. This is
conditional on the types of the the data being encoded. errchkjson finds
those calls which are unsafe, and also not checked for errors.
Add logging warnings to the place where unsafe encodings might happen.
This can help uncover usage bugs early in stash if they are tripped,
making debugging easier.
While here, keep the checker enabled in the linter to capture future
uses of json marshalling.
* Pass the context for zip file scanning.
* Pass the context in scanning
* Pass context, replace context.TODO()
Where applicable, pass the context down toward the lower functions in
the call stack. Replace uses of context.TODO() with the passed context.
This makes the code more context-aware, and you can rely on aborting
contexts to clean up subsystems to a far greater extent now.
I've left the cases where there is a context in a struct. My gut feeling
is that they have solutions that are nice, but they require more deep
thinking to unveil how to handle it.
* Remove context from task-structs
As a rule, contexts are better passed explicitly to functions than they
are passed implicitly via structs. In the case of tasks, we already
have a valid context in scope when creating the struct, so remove ctx
from the struct and use the scoped context instead.
With this change it is clear that the scanning functions are under a
context, and the task-starting caller has jurisdiction over the context
and its lifetime. A reader of the code don't have to figure out where
the context are coming from anymore.
While here, connect context.TODO() to the newly scoped context in most
of the scan code.
* Remove context from autotag struct too
* Make more context-passing explicit
In all of these cases, there is an applicable context which is close
in the call-tree. Hook up to this context.
* Simplify context passing in manager
The managers context handling generally wants to use an outer context
if applicable. However, the code doesn't pass it explicitly, but stores
it in a struct. Pull out the context from the struct and use it to
explicitly pass it.
At a later point in time, we probably want to handle this by handing
over the job to a different (program-lifetime) context for background
jobs, but this will do for a start.
* Avoid redundant logging in migrations
Return the error and let the caller handle the logging of the error if
needed.
While here, defer m.Close() to the function boundary.
* Treat errors as values
Use %v rather than %s and pass the errors directly.
* Generate a wrapped error on stat-failure
* Log 3 unchecked errors
Rather than ignore errors, log them at
the WARNING log level.
The server has been functioning without these, so assume they are not at
the ERROR level.
* Propagate errors upward
Failure in path generation was ignored. Propagate the errors upward the
call stack, so it can be handled at the level of orchestration.
* Warn on errors
Log errors rather than quenching them.
Errors are logged at the Warn-level for now.
* Check error when creating test databases
Use the builtin log package and stop the program fatally on error.
* Add warnings to uncheck task errors
Focus on the task system in a single commit, logging unchecked
errors as warnings.
* Warn-on-error in API routes
Look through the API routes, and make sure errors are being logged if
they occur. Prefer the Warn-log-level because none of these has proven
to be fatal in the system up until now.
* Propagate error when adding Util API
* Propagate error on adding util API
* Return unhandled error
* JS log API: propagate and log errors
* JS Plugins: log GQL addition failures.
* Warn on failure to write to stdin
* Warn on failure to stop task
* Wrap viper.BindEnv
The current viper code only errors if no name is provided, so it should
never fail. Rewrite the code flow to factor through a panic-function.
This removes error warnings from this part of the code.
* Log errors in concurrency test
If we can't initialize the configuration, treat the test as a failure.
* Warn on errors in configuration code
* Plug an unchecked error in gallery zip walking
* Warn on screenshot serving failure
* Warn on encoder screenshot failure
* Warn on errors in path-handling code
* Undo the errcheck on configurations for now.
* Use one-line initializers where applicable
rather than using
err := f()
if err!= nil { ..
prefer the shorter
if err := f(); err != nil { ..
If f() isn't too long of a name, or wraps a function with a body.
