* Push scrapeByURL into scrapers
Replace ScrapePerfomerByURL, ScrapeMovie..., ... with ScrapeByURL in
the scraperActionImpl interface. This allows us to delete a lot of
repeated code in the scrapers and replace the central part with a
switch on the scraper type.
* Fold name scraping into one call
Follow up on scraper refactoring. Name scrapers use the same code path.
This allows us to restructure some code and kill some functions, adding
variance to the name scraping code. It allows us to remove some code
repetition as well.
* Do not export loop refs.
* Simplify fragment scraping
Generalize fragment scrapers into ScrapeByFragment. This simplifies
fragment code flows into a simpler pathing which should be easier
to handle in the future.
* Eliminate more context.TODO()
In a number of cases, we have a context now. Use the context rather than
TODO() for those cases in order to make those operations cancellable.
* Pass the context for the stashbox scraper
This removes all context.TODO() in the path of the stashbox scraper,
and replaces it with the context that's present on each of the paths.
* Pass the context into subscrapers
Mostly a mechanical update, where we pass in the context for
subscraping. This removes the final context.TODO() in the scraper
code.
* Warn on unknown fields from scripts
A common mistake for new script writers are that they return fields
not known to stash. For instance the name "description" is used rather
than "details".
Decode disallowing unknown fields. If this fails, use a tee-reader to
fall back to the old behavior, but print a warning for the user in this
case. Thus, we retain the old behavior, but print warnings for scripts
which fails the more strict unknown-fields detection.
* Nil-check before running the postprocessing chain
Fixes panics when scraping returns nil values.
* Lift nil-ness in post-postprocessing
If the struct we are trying to post-process is nil, we shouldn't
enter the postprocessing flow at all. Pass the struct as a value
rather than a pointer, eliminating nil-checks as we go. Use the
top-level postProcess call to make the nil-check and then abort there
if the object we are looking at is nil.
* Allow conversion routines to handle values
If we have a non-pointer type in the interface, we should also convert
those into ScrapedContent. Otherwise we get errors on deprecated
functions.
* Add Cookies directly to the request
Rather than maintaining a cookie jar on a one-shot HTTP client, maintain
the jar ourselves: make a new jar, then use it to select the right
cookies.
The cookies are set on the request rather than on the client. This will
retain the current behavior as we are always throwing the client away
after each use.
This patch enables the lifting of the http client as well over time.
* Introduce a cached scraper HTTP client
The scraper cache is augmented with an *http.Client. These are safe for
concurrent use, so the pointer can safely be passed around. Push this
into scraper configurations where applicable, next to the txnManagers.
When we issue a loadUrl request, do so on the cached *http.Client,
which will reuse existing idle connections in the client if any are
present.
* Set MaxIdleConnsPerHost. Closes#1850
We allow for up to 8 idle connections to a single host. This should
make concurrent operation toward the same host reuse connections, even
for sizeable concurrency.
The number isn't bumped excessively high. We should probably limit
concurrency toward a single site anyway, since we'll be able to overrun
a site with queries quite easily if we have many concurrent goroutines
issuing requests at the same time.
* Reinstate driverOptions / useCDP check
Use DeMorgan's laws to invert the logic and exit early. Fixes tests
breaking.
* Documentation fixup.
* Use the scraper http.Client when fetching images
Fold image fetchers onto the cached scraper http.Client as well. This
makes the scraper have a single http.Client cache for all its
operations.
Thread the client upwards to the relevant attachment points: either the
cache, or a stash_box instance, which is extended to include a pointer
to the client.
Style roughly follows that of txnManagers.
* Use the same http Client as the GraphQL client use
Rather than using http.DefaultClient, use the same client as the
GraphQL client use in the stash_box subsystem. This localizes the
client used in the subsystem into the constructing New.. call.
* Hoist HTTP client construction
Create a function for initializaing the HTTP Client we use. While here
hoist magic numbers into constants. Introduce a proper static redirect
error and use it in the client code as well.
* Reinstate printCookies
This is a debugging function, and it might still come in handy in the
future at some point.
* Nitpick comment.
* Minor tidy

* Use the request context
The code uses context.Background() in a flow where there is a
http.Request. Use the requests context instead.
* Use a true context in the plugin example
Let AddTag/RemoveTag take a context and use that context throughout
the example.
* Avoid the use of context.Background
Prefer context.TODO over context.Background deep in the call chain.
This marks the site as something which we need to context-handle
later, and also makes it clear to the reader that the context is
sort-of temporary in the code base.
While here, be consistent in handling the `act` variable in each
branch of the if .. { .. } .. check.
* Prefer context.TODO over context.Background
For the different scraping operations here, there is a context
higher up the call chain, which we ought to use. Mark the call-sites
as TODO for now, so we can come back later on a sweep of which parts
can be context-lifted.
* Thread context upwards
Initialization requires context for transactions. Thread the context
upward the call chain.
At the intialization call, add a context.TODO since we can't break this
yet. The singleton assumption prevents us from pulling it up into main for
now.
* make tasks context-aware
Change the task interface to understand contexts.
Pass the context down in some of the branches where it is needed.
* Make QueryStashBoxScene context-aware
This call naturally sits inside the request-context. Use it.
* Introduce a context in the JS plugin code
This allows us to use a context for HTTP calls inside the system.
Mark the context with a TODO at top level for now.
* Nitpick error formatting
Use %v rather than %s for error interfaces.
Do not begin an error strong with a capital letter.
* Avoid the use of http.Get in FFMPEG download chain
Since http.Get has no context, it isn't possible to break out or have
policy induced. The call will block until the GET completes. Rewrite
to use a http Request and provide a context.
Thread the context through the call chain for now. provide
context.TODO() at the top level of the initialization chain.
* Make getRemoteCDPWSAddress aware of contexts
Eliminate a call to http.Get and replace it with a context-aware
variant.
Push the context upwards in the call chain, but plug it before the
scraper interface so we don't have to rewrite said interface yet.
Plugged with context.TODO()
* Scraper: make the getImage function context-aware
Use a context, and pass it upwards. Plug it with context.TODO()
up the chain before the rewrite gets too much out of hand for now.
Minor tweaks along the way, remove a call to context.Background()
deep in the call chain.
* Make NOTIFY request context-aware
The call sits inside a Request-handler. So it's natural to use the
requests context as the context for the outgoing HTTP request.
* Use a context in the url scraper code
We are sitting in code which has a context, so utilize it for the
request as well.
* Use a context when checking versions
When we check the version of stash on Github, use a context. Thread
the context up to the initialization routine of the HTTP/GraphQL
server and plug it with a context.TODO() for now.
This paves the way for providing a context to the HTTP server code in a
future patch.
* Make utils func ReadImage context-aware
In almost all of the cases, there is a context in the call chain which
is a natural use. This is true for all the GraphQL mutations.
The exception is in task_stash_box_tag, so plug that task with
context.TODO() for now.
* Make stash-box get context-aware
Thread a context through the call chain until we hit the Client API.
Plug it with context.TODO() there for now.
* Enable the noctx linter
The code is now free of any uncontexted HTTP request. This means we
pass the noctx linter, and we can enable it in the code base.
* Enable safe linters
Enable the linters dogsled, rowserrcheck, and sqlclosecheck.
These report no errors currently in the code base.
Enable misspell.
Misspell finds two spelling mistakes in comments, which are fixed by the
patch as well.
Add and sort linters which are relatively
safe to add over time. Comment them out for now.
* Close the response body
If we can get a HTTP response, it has a body which ought to be closed.
By doing so, we avoid potentially leaking connections.
* Enable the exportloopref linter
There are two places in the code with these warnings. Fix them while
enabling the linter.
* Remove redundant types in tests
If a slice already determines the type, the inner type declaration is
redundant. Remove the inner declarations.
* Mark autotag test cases as parallel
Autotag test cases is by far the outlier when it comes to test time.
While go test runs test cases in parallel,
it doesn't do so inside a given package, unless one marks the test cases
as parallel.
This change provides a significant speedup on a 8-core machine for test
runs.
The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

* Remove stuff which isn't being used
Some fields, functions and structs aren't in use by the project. Remove
them for janitorial reasons.
* Remove more unused code
All of these functions are currently not in use. Clean up the code by
removal, since the version control has the code if need be.
* Remove unused functions
There's a large set of unused functions and variables in the code base.
Remove these, so it clearer what code to support going forward.
Dead code has been eliminated.
Where applicable, comment const-sections in tests, so reserved
identifiers are still known.
* Fix use-def of tsURL
The first def of tsURL doesn't matter because there's no use before
we hit the 2nd def.
* Remove dead code assignment
Setting logFile = "" is effectively dead code, because there's no use
of it later.
* Comment out found
The variable 'found' is dead in the function (because no post-process
action is following it). Comment it for now.
* Comment dead code in tests
These might provide hints as to what isn't covered at the moment.
* Dead code removal
In the case of constants where iota is involved, move the iota so it
matches the current key values.
This avoids problems with persistently stored key IDs.
* Fix error string capitalization
Error strings often follow another string. Hence, they should not be
capitalized, unless referencing a name.
* Uncapitalize more error strings
While here, use %v on the error directly, which makes it easier to wrap
the error later with %w if need be.
* Uncapitalize more error strings
While here, rename Url to URL as a nitpick.
* Make config instance-based
* Remove config dependency in paths
* Refactor config init
* Allow startup without database

* Handle metadata not set during full import/export
* Add links
* Remove config check middleware
* Stash not mandatory
* Panic on missing mandatory config fields
* Redirect setup to main page if setup not required
* Add migration UI
* Remove unused stuff
* Move UI initialisation into App
* Don't create metadata paths on RefreshConfig
* Add folder selector for generated in setup
* Env variable to set and create config file.
Make docker images use a fixed config file.
* Set config file during setup
