Enable gocritic (#1848) * Don't capitalize local variables ValidCodecs -> validCodecs * Capitalize deprecation markers A deprecated marker should be capitalized. * Use re.MustCompile for static regexes If the regex fails to compile, it's a programmer error, and should be treated as such. The regex is entirely static. * Simplify else-if constructions Rewrite else { if cond {}} to else if cond {} * Use a switch statement to analyze formats Break an if-else chain. While here, simplify code flow. Also introduce a proper static error for unsupported image formats, paving the way for being able to check against the error. * Rewrite ifElse chains into switch statements The "Effective Go" https://golang.org/doc/effective_go#switch document mentions it is more idiomatic to write if-else chains as switches when it is possible. Find all the plain rewrite occurrences in the code base and rewrite. In some cases, the if-else chains are replaced by a switch scrutinizer. That is, the code sequence if x == 1 { .. } else if x == 2 { .. } else if x == 3 { ... } can be rewritten into switch x { case 1: .. case 2: .. case 3: .. } which is clearer for the compiler: it can decide if the switch is better served by a jump-table then a branch-chain. * Rewrite switches, introduce static errors Introduce two new static errors: * `ErrNotImplmented` * `ErrNotSupported` And use these rather than forming new generative errors whenever the code is called. Code can now test on the errors (since they are static and the pointers to them wont change). Also rewrite ifElse chains into switches in this part of the code base. * Introduce a StashBoxError in configuration Since all stashbox errors are the same, treat them as such in the code base. While here, rewrite an ifElse chain. In the future, it might be beneifical to refactor configuration errors into one error which can handle missing fields, which context the error occurs in and so on. But for now, try to get an overview of the error categories by hoisting them into static errors. * Get rid of an else-block in transaction handling If we succesfully `recover()`, we then always `panic()`. This means the rest of the code is not reachable, so we can avoid having an else-block here. It also solves an ifElse-chain style check in the code base. * Use strings.ReplaceAll Rewrite strings.Replace(s, o, n, -1) into strings.ReplaceAll(s, o, n) To make it consistent and clear that we are doing an all-replace in the string rather than replacing parts of it. It's more of a nitpick since there are no implementation differences: the stdlib implementation is just to supply -1. * Rewrite via gocritic's assignOp Statements of the form x = x + e is rewritten into x += e where applicable. * Formatting * Review comments handled Stash-box is a proper noun. Rewrite a switch into an if-chain which returns on the first error encountered. * Use context.TODO() over context.Background() Patch in the same vein as everything else: use the TODO() marker so we can search for it later and link it into the context tree/tentacle once it reaches down to this level in the code base. * Tell the linter to ignore a section in manager_tasks.go The section is less readable, so mark it with a nolint for now. Because the rewrite enables a ifElseChain, also mark that as nolint for now. * Use strings.ReplaceAll over strings.Replace * Apply an ifElse rewrite else { if .. { .. } } rewrite into else if { .. } * Use switch-statements over ifElseChains Rewrite chains of if-else into switch statements. Where applicable, add an early nil-guard to simplify case analysis. Also, in ScanTask's Start(..), invert the logic to outdent the whole block, and help the reader: if it's not a scene, the function flow is now far more local to the top of the function, and it's clear that the rest of the function has to do with scene management. * Enable gocritic on the code base. Disable appendAssign for now since we aren't passing that check yet. * Document the nolint additions * Document StashBoxBatchPerformerTagInput

Hoist context, enable errchkjson (#2488) * 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.

Errorlint sweep + minor linter tweaks (#1796) * Replace error assertions with Go 1.13 style Use `errors.As(..)` over type assertions. This enables better use of wrapped errors in the future, and lets us pass some errorlint checks in the process. The rewrite is entirely mechanical, and uses a standard idiom for doing so. * Use Go 1.13's errors.Is(..) Rather than directly checking for error equality, use errors.Is(..). This protects against error wrapping issues in the future. Even though something like sql.ErrNoRows doesn't need the wrapping, do so anyway, for the sake of consistency throughout the code base. The change almost lets us pass the `errorlint` Go checker except for a missing case in `js.go` which is to be handled separately; it isn't mechanical, like these changes are. * Remove goconst goconst isn't a useful linter in many cases, because it's false positive rate is high. It's 100% for the current code base. * Avoid direct comparison of errors in recover() Assert that we are catching an error from recover(). If we are, check that the error caught matches errStop. * Enable the "errorlint" checker Configure the checker to avoid checking for errorf wraps. These are often false positives since the suggestion is to blanket wrap errors with %w, and that exposes the underlying API which you might not want to do. The other warnings are good however, and with the current patch stack, the code base passes all these checks as well. * Configure rowserrcheck The project uses sqlx. Configure rowserrcheck to include said package. * Mechanically rewrite a large set of errors Mechanically search for errors that look like fmt.Errorf("...%s", err.Error()) and rewrite those into fmt.Errorf("...%v", err) The `fmt` package is error-aware and knows how to call err.Error() itself. The rationale is that this is more idiomatic Go; it paves the way for using error wrapping later with %w in some sites. This patch only addresses the entirely mechanical rewriting caught by a project-side search/replace. There are more individual sites not addressed by this patch.

Toward better context handling (#1835) * 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.

Add golangci-lint workflow (#1759) * Add golangci-lint workflow * Add a bit more lenient linter timeout 1 Minute isn't always enough, so bump to 3. * Document golangci, add make target Document how to get golangci-lint in the README file. While here, provide a QOL target in the makefile for the linter, and make it part of validation. * Introduce .golangci.yml This is the default golangci-lint configuration file location. Use it. Move configuration into the yaml file, and enable the default set of linters; we know we pass most of those. * Add gofmt and revive to golangci-lint Read the golangci-lint source code to figure out the configuration format. Copy the configuration from `revive.toml` into the linter configuration. * Do not set simplify on gofmt The project currently runs without simplify. So for consistency, don't make that a requirement for the linter. * Add new-from-rev Older issues should not be considered a failure for new PRs and issues. Use new-from-from to make the current develop as the point-in-time for when we consider errors. Once in the tree, we can go and fix the older errors in separate patches, taking a little bit at a time. * Move to golangci-lint Rewrite the way we run targets in the makefile, so it is split between frontend and backend. Use the frontend build steps in build.yml Update README to reflect the new world order. * Remove check-gofmt.sh The tool now runs as part of golangci-lint, in particular through the 'validate' target in the Makefile. * Remove targets for golangci-lint Fold these targets into the `lint` target. While here, update README.

Errorlint sweep + minor linter tweaks (#1796) * Replace error assertions with Go 1.13 style Use `errors.As(..)` over type assertions. This enables better use of wrapped errors in the future, and lets us pass some errorlint checks in the process. The rewrite is entirely mechanical, and uses a standard idiom for doing so. * Use Go 1.13's errors.Is(..) Rather than directly checking for error equality, use errors.Is(..). This protects against error wrapping issues in the future. Even though something like sql.ErrNoRows doesn't need the wrapping, do so anyway, for the sake of consistency throughout the code base. The change almost lets us pass the `errorlint` Go checker except for a missing case in `js.go` which is to be handled separately; it isn't mechanical, like these changes are. * Remove goconst goconst isn't a useful linter in many cases, because it's false positive rate is high. It's 100% for the current code base. * Avoid direct comparison of errors in recover() Assert that we are catching an error from recover(). If we are, check that the error caught matches errStop. * Enable the "errorlint" checker Configure the checker to avoid checking for errorf wraps. These are often false positives since the suggestion is to blanket wrap errors with %w, and that exposes the underlying API which you might not want to do. The other warnings are good however, and with the current patch stack, the code base passes all these checks as well. * Configure rowserrcheck The project uses sqlx. Configure rowserrcheck to include said package. * Mechanically rewrite a large set of errors Mechanically search for errors that look like fmt.Errorf("...%s", err.Error()) and rewrite those into fmt.Errorf("...%v", err) The `fmt` package is error-aware and knows how to call err.Error() itself. The rationale is that this is more idiomatic Go; it paves the way for using error wrapping later with %w in some sites. This patch only addresses the entirely mechanical rewriting caught by a project-side search/replace. There are more individual sites not addressed by this patch.
