Clojurians Log v2
releases
https://github.com/seancorfield/deps-new https://github.com/seancorfield/deps-new/releases/tag/v0.10.1 -- Create new projects for the Clojure CLI / deps.edn:
• Although this is a minor release, it paves the way for much more flexible templates in the future, and offers examples of how to write templates that need conditional logic.
• clojure -Ttools install-latest :lib io.github.seancorfield/deps-new :as new
• Address https://github.com/seancorfield/deps-new/issues/66 by reimplementing :test-runner and :build options purely in terms of :data-fn and :template-fn options in template.edn files.
• Address https://github.com/seancorfield/deps-new/issues/65 by allowing :data-fn, :template-fn, and :post-process-fn to accept either a single symbol or a sequence of symbols, to support multiple transformations in order.
• Address https://github.com/seancorfield/deps-new/issues/59 by clarifying how options end up in the data hash map.
• Update tools.build to 0.10.10.

io.pedestal/pedestal 0.8.0-rc-1
Pedestal is a set of Clojure libraries that bring the core Clojure principles - Simplicity, Power, and Focus - to
server-side development.
https://github.com/pedestal/pedestal
This release is the same as 0.8.0-beta-3, except that a few dependency version have been bumped to latest.
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
• Fixed reloading behavior when namespaces are reloaded via https://github.com/tonsky/clj-reload
• 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)
• 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:
• 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)
• Deprecation warnings may now be suppressed
• Metrics can now be configured to accept longs or doubles as their values.
• 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
◦ io.pedestal.connector.servlet and new Java class ConnectorServlet allow for WAR deployments
• WebSockets are now routable 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 pedestal.servlet module
• 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 io.pedestal.http.route.definition.table/table-routes may now be nil or a map
• It is now possible to specify the maximum number of concurrent threads with the Jetty HTTP2 and HTTP2C connection
factories
• 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
◦ 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
• 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 io.pedestal.http.cors/allow-origin interceptor now, by default, logs at level debug (was level info previously)
• Development mode is now configured as with other values, rather than strictly via a JVM system property
• The embedded template now generates a less rudimentary index page, with basic styling
