Clojurians Log v2

https://github.com/clj-commons/slingshot -- Enhanced try and throw for Clojure leveraging Clojure's capabilities -- has moved to clj-commons for maintenance and future development: org.clj-commons/slingshot {:mvn/version "0.13.0"} should be functionally identical to slingshot/slingshot {:mvn/version "0.12.2"} but the namespaces have changed to have a clj-commons prefix to avoid conflicts with older versions on the classpath, since this is such a widely-used library: • add clj-kondo config export • move to clj-commons; rename nses to clj-commons.* • switch to CLI / deps.edn / build.clj / bb.edn • add GitHub Actions for CI • drop support for Clojure 1.7 and earlier • clean up use and refer all Note: slingshot/slingshot supported Clojure 1.4 onward (although the test suite was failing on 1.8 onward). org.clj-commons/slingshot officially supports Clojure 1.8 through 1.12 and may work on earlier versions. Given the time passed since 0.12.2, this seemed a reasonable modernization. Follow-up in #slingshot

io.pedestal/pedestal 0.8.0 https://pedestal.io is a framework that brings Clojure’s key attributes, Focus, Empowerment, and Simplicity, to the domain of Clojure web development. Version 0.8.0 represents more than a year of steady improvements. OVERVIEW: • Routing ◦ New Sawtooth router favors literal paths over those with path parameters, and can report any routing conflicts ◦ WebSocket upgrade requests now go through routing, the same as any other endpoint (previously handled as special case) ◦ Static files (file system or on JVM classpath) now also go through routing (previously handled via interceptors) • Servlet Support ◦ Upgraded to Jetty 12 • Non-Servlet Support ◦ Pedestal APIs that require Jakarta Servlet APIs are now in a new module, io.pedestal/pedestal.servlet ◦ Pedestal now supports non-servlet based HTTP libraries, such as https://github.com/http-kit/http-kit • Developer Experience ◦ io.pedestal.http replaced with simpler, streamlined io.pedestal.connector ◦ Improved REPL-oriented development, compatible with https://github.com/tonsky/clj-reload ◦ New definterceptor to create a record type that can be used as an interceptor ◦ Significant improvements to all documentation BREAKING CHANGES: • Clojure 1.11 is now the minimum supported version • The new Sawtooth router is now the default router • Anonymous interceptors are deprecated • Many APIs deprecated in Pedestal 0.7.0 have been removed outright • The io.pedestal/pedestal.service-tools library has been removed • Significant changes to io.pedestal.http.route have occurred • Server-Sent Events have been changed; fields are now terminated with a single \n rather than a \r\n (both are acceptible according to the SSE specification) • The io.pedestal.http.body-params/body-params interceptor now does nothing if the request :body is nil • Exceptions in interceptors: ◦ The caught exception is now the ex-cause of the exception provided (in earlier releases, it was the :exception key of the data) ◦ The logic for when to suppress an exception thrown from the error handling interceptor has been simplified: always suppress except when the interceptor rethrows the exact error passed to it • io.pedestal.test has been rewritten, nearly from scratch ◦ The Servlet API mocks are now standard Java classes, not reify-ed classes ◦ A request body may now be a java.io.File • io.pedestal.http.servlet ◦ The reify’ed FnServlet class is now a standard Java class, io.pedestal.servlet.FnServlet ◦ The new FnServlet extends HttpServlet not Servlet • Deleted deprecated namespaces: ◦ io.pedestal.http.request ◦ io.pedestal.http.request.lazy ◦ io.pedestal.http.request.zerocopy • Deleted vars (previously deprecated): ◦ io.pedestal.http ▪︎ json-print ◦ io.pedestal.http.body-params ▪︎ add-ring-middleware ▪︎ edn-parser ▪︎ json-parser ▪︎ transit-parser ◦ io.pedestal.http.ring-middlewares ▪︎ response-fn-adapter ◦ io.pedestal.http.impl.servlet-interceptor ▪︎ stylobate ▪︎ terminator-injector • Other deleted vars and namespaces: ◦ io.pedestal.http.route.definition/symbol->keyword ◦ io.pedestal.http.route.definition/capture-constraint ◦ io.pedestal.http.request.servlet-support Newly deprecated namespaces (these may be removed or made non-public in the future): • io.pedestal.jetty.container • io.pedestal.jetty.util • io.pedestal.http • io.pedestal.http.test Other changes: • Pedestal Connectors are a new abstraction around an HTTP library such as Jetty or Http-Kit ◦ Connectors do not use the Servlet API, and so are much lighter weight ◦ The io.pedestal.connector namespace is used to configure and start a Pedestal connector • A new router, io.pedestal.http.route.sawtooth, has been added ◦ Sawtooth identifies conflicting routes ◦ Sawtooth prefers literal routes over routes with path parameters (i.e., /users/search vs. /users/:id) ◦ Sawtooth is the now the default router • When converting a handler function to an Interceptor ◦ Handler functions may now be asynchronous, returning a channel that conveys the response map ◦ The :name metadata on the function will be used as the :name of the interceptor ◦ Otherwise, a :name is derived from the function’s class ◦ Previously, with the terse or verbose routing specifications, the route name would overwrite the (missing) name of the interceptor; now interceptors always have names and this does not occur ◦ Extracting default interceptor names from handlers can also be turned off, reverting to 0.7.x behavior • The new definterceptor macro is used to concisely define a record type that can be used as an interceptor, but also as a https://github.com/stuartsierra/component • Development mode is now configured as with other values, rather than strictly via a JVM system property • Deprecation warnings may now be suppressed • Fixed reloading behavior when namespaces are reloaded via https://github.com/tonsky/clj-reload • Metrics can now be configured to accept longs or doubles as their values • io.pedestal.connector.servlet and new Java class ConnectorServlet allow for WAR deployments • WebSockets are now routable like other requests, using new function io.pedestal.websocket/upgrade-request-to-websocket • The pedestal.service module has been broken up; all the parts specific to the Jakarta Servlet API are now in the new pedestal.servlet module • io.pedestal.http.route.definition.table • Table routes may now specify :interceptors (in the options map); these are prefixed on any interceptors provided by the routes in the table • Table routes may now include application-defined key/value pairs in addition to :route-name and :constraints • The first argument to table-routes may now be nil or a map • io.pedestal.http.jetty • It is now possible to specify the maximum number of concurrent threads with the Jetty HTTP2 and HTTP2C connection factories • It is now possible to specify WebSocket configuration (buffer sizes, timeouts) • New functions and macros: ◦ io.pedestal.test/create-responder - useful piece needed in most tests ◦ io.pedestal.interceptor/definterceptor - easily create component records that transform into interceptors ◦ io.pedestal.log/log - logs with level determined at runtime • New namespaces: ◦ io.pedestal.connector - Replaces io.pedestal.http for setting up a connector ◦ io.pedestal.service.protocols - Defines core protocols ◦ io.pedestal.service.resources - Expose resources using routes not interceptors ◦ - Development/debugging tools ◦ io.pedestal.service.interceptors - Common interceptors ◦ io.pedestal.connector.test - Testing w/ Ring request and response (no Servlet API) ◦ io.pedestal.connector.servlet - bridge to Pedestal from a WAR deployment • The io.pedestal.http.cors/allow-origin interceptor now, by default, logs at level debug (was level info previously) • The embedded template now generates a less rudimentary index page, with basic styling https://github.com/pedestal/pedestal/milestone/17?closed=1
