[ruby-talk:444745] [ANN] minitest 6.0.1 Released
by Ryan Davis 26 Dec '25

26 Dec '25

minitest version 6.0.1 has been released! * home: <https://minite.st/> * code: <https://github.com/minitest/minitest> * bugs: <https://github.com/minitest/minitest/issues> * rdoc: <https://docs.seattlerb.org/minitest> * clog: <https://github.com/minitest/minitest/blob/master/History.rdoc> * emacs: <https://github.com/arthurnn/minitest-emacs> * vim: <https://github.com/vim-test/vim-test> minitest provides a complete suite of testing facilities supporting TDD, BDD, and benchmarking. "I had a class with Jim Weirich on testing last week and we were allowed to choose our testing frameworks. Kirk Haines and I were paired up and we cracked open the code for a few test frameworks... I MUST say that minitest is *very* readable / understandable compared to the 'other two' options we looked at. Nicely done and thank you for helping us keep our mental sanity." -- Wayne E. Seguin minitest/test is a small and incredibly fast unit testing framework. It provides a rich set of assertions to make your tests clean and readable. minitest/spec is a functionally complete spec engine. It hooks onto minitest/test and seamlessly bridges test assertions over to spec expectations. minitest/benchmark is an awesome way to assert the performance of your algorithms in a repeatable manner. Now you can assert that your newb co-worker doesn't replace your linear algorithm with an exponential one! minitest/pride shows pride in testing and adds coloring to your test output. I guess it is an example of how to write IO pipes too. :P minitest/test is meant to have a clean implementation for language implementors that need a minimal set of methods to bootstrap a working test suite. For example, there is no magic involved for test-case discovery. "Again, I can't praise enough the idea of a testing/specing framework that I can actually read in full in one sitting!" -- Piotr Szotkowski Comparing to rspec: rspec is a testing DSL. minitest is ruby. -- Adam Hawkins, "Bow Before MiniTest" minitest doesn't reinvent anything that ruby already provides, like: classes, modules, inheritance, methods. This means you only have to learn ruby to use minitest and all of your regular OO practices like extract-method refactorings still apply. Changes: ### 6.0.1 / 2025-12-26 * 1 minor enhancement: * Added new rake task `test:fu` to Minitest::TestTask, to only run tests with FU (focused units?) in their name. This should mostly obviate the need for the minitest-focus plugin. * 5 bug fixes: * Fixed --help and --version exiting 1. (grosser) * Fixed method signature of Minitest::Benchmark.run. (flavorjones) * Flush stdout/stderr before exit./bin/minitest -Ilib ./bug1046.rb:1 < /dev/null (grosser) * Improved usage banner output by reordering and reformatting. * Normalize paths while processing file.rb:line args.

[ruby-talk:444739] [ANN] oedipus_lex 2.6.3 Released
by Ryan Davis 24 Dec '25

24 Dec '25

oedipus_lex version 2.6.3 has been released! * home: <http://github.com/seattlerb/oedipus_lex> * rdoc: <http://docs.seattlerb.org/oedipus_lex> Oedipus Lex is a lexer generator in the same family as Rexical and Rex. Oedipus Lex is my independent lexer fork of Rexical. Rexical was in turn a fork of Rex. We've been unable to contact the author of rex in order to take it over, fix it up, extend it, and relicense it to MIT. So, Oedipus was written clean-room in order to bypass licensing constraints (and because bootstrapping is fun). Oedipus brings a lot of extras to the table and at this point is only historically related to rexical. The syntax has changed enough that any rexical lexer will have to be tweaked to work inside of oedipus. At the very least, you need to add slashes to all your regexps. Oedipus, like rexical, is based primarily on generating code much like you would a hand-written lexer. It is _not_ a table or hash driven lexer. It uses StrScanner within a multi-level case statement. As such, Oedipus matches on the _first_ match, not the longest (like lex and its ilk). This documentation is not meant to bypass any prerequisite knowledge on lexing or parsing. If you'd like to study the subject in further detail, please try [TIN321] or the [LLVM Tutorial] or some other good resource for CS learning. Books... books are good. I like books. Changes: ### 2.6.3 / 2025-12-24 * 1 minor enhancement: * Bump ruby to 3.2+.

[ruby-talk:444736] [ANN] httpx 1.7.0 released
by Tiago Cardoso 24 Dec '25

24 Dec '25

httpx 1.7.0 has been released. ``` HTTPX.get("https://gitlab.com/honeyryderchuck/httpx <https://gitlab.com/honeyryderchuck/httpx>") ``` HTTPX is an HTTP client library for the Ruby programming language. Among its features, it supports: * HTTP/2 and HTTP/1.x protocol versions * Concurrent requests by default * Simple and chainable API * Proxy Support (HTTP(S), CONNECT tunnel, Socks4/4a/5) * Simple Timeout System * Lightweight by default (require what you need) And also: * Compression (gzip, deflate, brotli) * Streaming Requests * Authentication (Basic Auth, Digest Auth, AWS Sigv4) * Expect 100-continue * Multipart Requests * Cookies * HTTP/2 Server Push * H2C Upgrade * Automatic follow redirects * International Domain Names * GRPC * Circuit breaker * WebDAV * SSRF Filter * Response caching * HTTP/2 bidirectional streaming * QUERY HTTP verb * Datadog integration * Faraday integration * Webmock integration * Sentry integration Here are the updates since the last release: # 1.7.0 ## Features ### All AUTH plugin improvements!! #### `:auth` The `:auth` plugin can now be used with a dynamic callable object (methods, procs...) to generate the token. ```ruby # static token, pre 1.7.0 HTTPX.plugin(:auth).authorization("API-TOKEN") # dynamically generate token! HTTPX.plugin(:auth).authorization { generate_new_ephemeral_token } ``` The `.authorization` method is now syntactic sugar for a new option, `:auth_header_value`, which can be used directly, alongside a `:auth_header_type`: ```ruby HTTPX.plugin(:auth).authorization("API-TOKEN") HTTPX.plugin(:auth).authorization { generate_new_ephemeral_token } HTTPX.plugin(:auth).authorization("Bearer API-TOKEN") # same as HTTPX.plugin(:auth, auth_header_value: "API-TOKEN") HTTPX.plugin(:auth, auth_header_value: -> { generate_new_ephemeral_token }) HTTPX.plugin(:auth, auth_header_type: "Bearer", auth_header_value: "API-TOKEN") ``` A new option `:generate_auth_value_on_retry` (which can be passed a callable receiving a response object) is now available; when used alongside the `:retries` plugin, it'll use the callable passed to the `.authorization` method to generate a new token before retrying the request: ```ruby authed = HTTPX.plugin(:retries).plugin(:auth, generate_auth_value_on_retry: ->(res) { res.status == 401 }).authorization { generate_new_ephemeral_token } authed.get("https://example.com") ``` Read more about it in the [auth plugin wiki]( https://honeyryderchuck.gitlab.io/httpx/wiki/Auth) #### `:oauth` The `:oauth` plugin implementation was revamped to make use of the `:auth` plugin new functionality, in order to make managing an oauth session more seamless. Take the following example: ```ruby session = HTTPX.plugin(:oauth).with_oauth_options( issuer: server.origin, client_id: "CLIENT_ID", client_secret: "SECRET", ) session.get("https://example.com") #=> will load server metadata, request an access token, and perform the request with the access token. # 2 hours later... session.get("https://example.com") # it'll reuse the same acces token, and if the request fails with 401, it'll request a new # access token using the refresh token grant (when supported by the token issuer), and # reperform the original request with the new access token. ``` A new option, `:oauth_options`, is now available. The same parameters previously supported by the `:oauth_session` options are supported. The following components are therefore deprecated and scheduled for removal in a future major version: * `:oauth_session` option * `.oauth_auth` session method * `.with_access_token` session method #### `:bearer_auth`, `:digest_auth`; `:ntlm_auth` The `:auth` plugin is now the foundation of each of these plugins, which haven't suffered major API changes. Read more about it in the [auth plugin wiki]( https://honeyryderchuck.gitlab.io/httpx/wiki/OAuth) ### `:retries` plugin: `:retry_after` backoff algorithms The `:retries` plugins supports two new possible values for the `:retry_after` option: `:exponential_backoff` and `:polynomial_backoff`. They'll implement the respective calculation per each retry of a given request. ```ruby # will wait 1, 2, 4, 8, 16 seconds... depending of how many retries it can wait for session = HTTPX.plugin(:retries, retry_after: :exponential_backoff) ``` Read more about it in the [retries plugin wiki]( https://honeyryderchuck.gitlab.io/httpx/wiki/Retries) ### Ractor compatibility `httpx` can be used within a ractor: ```ruby # ruby 4.0 syntax response = Ractor.new(uri) do |uri| HTTPX.get(uri) end.value ``` Bear in mind that, if you're connection via HTTPS, you'll need make sure you're using version 4.0 or higher of the `openssl` gem. The test suite isn't exhaustive for ractors yet, but most plugins should also be ractor-compatible. If they don't work, that's a bug, and you're recommended to report it. ## Improvements * When encoding the `:json` param to send it as `application/json` payload, (example: `HTTPX.post("https://example.com", json: { foo: "bar })`), and the method uses the `json` standard library, it'll use `JSON.generate` (instead of `JSON.dump`) to encode the JSON payload. The reason is that, unlike `JSON.dump`, it doesn't rely on access to a global mutable hash, and is therefore ractor-safe. * `:stream` plugin: the stream response class (the object that is returned in request calls is a stream response) can be extended now. You can add a `StreamResponseMethods` method to your plugin. Read more about it in the documentation. * The resolver name cache (used by the native and https resolvers) was remade into a LRU cache, and will therefore not keep on growing when `httpx` is used to connect to a huge number of hostnames in a process. * the native and https DNS resolvers will ignore answers with SERVFAIL code while there are retries left (some resolvers use such error code for rate limiting). * `:timeout` option values are now validated, and an error is raised when passing an unrecognized timeout option (which is a good layer of protection for typos). * pool: try passing the scheduler to a thread waiting on a connection, to avoid the current case where a connection may be checked-in-then-immediately-out-after when doing multiple requests in a loop, never giving a chance to others and potentially making the pool time out. * headers deep-freeze and dup. ## Bugfixes * recover and close connection when an `IOError` is raised while waiting for IO readiness (could cause busy loops during HTTP/2 termination handshake). * `:stream_bidi` plugin: improve thread-safety of buffer operations when the session is used from multiple threads. * `:stream_bidi` plugin: added missing methods to signal in order to comply with the Selectable API (it was reported as raising `NoMethodError` under certain conditions). * `:stream_bidi` plugin: can support non-bidirectional stream requests using the same session. * `:stream` plugin: is now compatible with fiber scheduler engines (via the `:fiber_concurrency` plugin). * `:stream` plugin: make sure that stream long-running requests do not share the same connection as regular threads. * `:digest_auth` plugin: can now support qop values wrapped inside parentheses in the `www-authenticate` header (i.e. `qop="('auth',)"`). * https resolver: handle 3XX redirect responses in HTTP DNS queries. * https resolver: do not close HTTP connections whhich are shared across AAAA and A resolution paths when its in use by one of them. * fix access to private method from `http-2` which was made public in more recent versions, but not in older still-supported versions. * fixed resolver log message using a "connection" label. * `HTTPX::Response.copy_to` will explicitly close the response at the end; given that the body file can be moved as a result, there is no guarantee that the response is still usable, so might as well just close it altogether. * selector: avoid skipping persistent connections in the selector to deactivate due to iterate-and-modify. ## Breaking Changes ### `:digest_auth` error The main error class for the `:digest_auth` plugin has been moved to a different location. If you were rescuing the `HTTPX::Plugins::DigestAuth::DigestError` error, you should now point to the `HTTPX::Authentication::Digest::Error`. ### `:stream` plugin: `build_request` should receive `stream: true` for stream requests In case you're building request objects before passing them to the session, you're now forced to create them with the `:stream` option on: ```ruby session = HTTPX.plugin(:stream) # before req = session.build_request("GET", "https://example.com/stream") session.request(req, stream: true) # after req = session.build_request("GET", "https://example.com/stream", stream: true) session.request(req) ``` Previous code may still work in a few cases, but it is not guaranteed to work on all cases. # 1.6.3 ## Features * allow redacting only headers, or only the body, when using `debug_redact: :headers` or `debug_redact: :body` respectively. ## Improvements * `system` resolver now works in a non-blocking manner, initiating the dns query in a separate thread and waiting on the pipe after that (it was blocking the main thread during resolution before). * reduce allocation to a single shared option object when headers are passed as a session-level option, like `HTTPX.with(headers: headers).get(...)` * favour using `String#replace` in buffer operations (instead of "clean-then-append"). * using `Array#unshift` instead of `Array#concat` in order to ensure that request ordering is respected in the face of an in-between error which requires reconnect-and-resend. * replaced more internal callback indirection with plain method calls. ## Bugfixes * https: prevent modification of the ssl context object when performing a reconnection. * compression: do not return early if the decompression buffer yields an empty string (more frequent under jruby 10). * response cache: take query params into account when caching or retrieving cached responses. * response cache: do not decompress cached responses on body consumption (the response bodies are cached in plaintext). * native resolver: pick next timeout associated with the hostname being resolved (and not the hostnames in the queue). * pool: assume that, even when signalled that a connection is available, context may be switched to a session which also checks the same connection out, before it's able to pick it up; in such a case, start from the beginning, until the pool timeout expires. * session: forego bookkeeping when a connection is coalesced (instead, allow it to be dropped). * digest_auth: make sure that an array is sent back if the probe response fails. * alt-svc: when alt-svc handshake happens with more in-flight requests, defer termination to when these requests are made. * http2: fix use of unexisting var `ex` when processing the connection closed callback. * connection: fix potential session dereferencing, which allowed connections to be used across sessions, therefore bypassing needed synchronization and leading to the `undefined method 'after' for nil:NilClass` error. * selector: close only selected connections (instead of all selectable connections) when an error occurs during IO readiness wait calls. * resolvers: correctly propagate abrupt termination errors to the connection objects waiting for the answer. * resolvers: when errors happenm force-close unresolved connections (and ensure they're both pinned to the corresponding session before the error happens, and are unpinned after error is propagated). * resolvers: ensure resolvers transition to "closed" state, on all cases, when any error happens. * resolvers: ensure that the next hostname is resolved when a timeout happens on the current one. * native resolver: fixed duplication of the hostname to resolve in the list of candidates. * https resolver: use a `system` resolver to resolve the DoH server hostname (instead of rerouting it to itself). * https resolver: skip loop error reporting when error happens outside of it. * https resolver: close connection on resolve errors, which prevents it from being around in the pool after termination; also deactivate it after successful use. * multi resolver: do not check resolvers back into the pool if it's a multi resolver and the peer is still resolving (and do the check outside of the critical area). * sentry adapter: removed usage of deprecated method which has been removed in sentry-ruby 6.0.0. * selector: when coalescing connections, pin the current session before merging connections, to prevent it from registering in a selector being used in a different thread, and inadvertedly allowing it to be used across threads. * session: fix: always pin connection before early-or-lazy resolution (fixes connection pool accounting under connection coalescing). ## Chores * logging emits a timestamp as well (to monitor timeouts). * `:stream_bidi` plugin: extends HTTP2 module by using plugin extensions. * connection: remove session/selector references when closing a connection (prevents leaking them beyond the usage scope). # 1.6.2 ## Bugfixes * revert of behaviour introduced in 1.6.1 around handling of `:ip_families` for name resolution. * when no option is passed, do not assume no IPv6 connectivity if no available non-local IP is found, as the local network may still be reachable under `[::]`. * bail out connection if the tcp connection was established but the ssl session failed. * when alpn negotiation succeeded, this could still initialize the HTTP/2 connection and put bytes in the buffer, which would cause a busy loop trying to write to a non-open socket. * datadog: fix initialization of spans in non-connection related errors * past code was relying on the error being around DNS, but other errors could pop; the fix was moving the init time setup early to the session, when a request is first passed ot the associated connection. * it can also fail earlier, so provide a workaround for that as well. # 1.6.1 ## Improvements * `:oauth` plugin: `.oauth_session` can be called with an `:audience` parameter, which has the effect of adding it as an extra form body parameter of the token request. ## Bugfixes * options: when freezing the options, skip freezing `:debug`; it's usually a file/IO/stream object (stdout, stderr...), which makes it error when log messages are written. * tcp: fixed adding IPv6 addresses to a tcp object when IPv4 connection probe is ongoing so that the next try uses the first ipv6 address. * tcp: reorder addresses on reconnection, so ipv6 is tried first in case it is still valid. * tcp: make sure ip index is decremented on error, so the next tried IP may be a valid one. * tcp: do not reattempt connecting if there are no available addresses to connect. This may happen in a fiber-aware context, where fiber A waits on connection, fiber B reconnects as a result on an error or GOAWAY frame and waits on the resolver DNS answer, and when context is passed back to fiber B, it should go back to the invalidate the response and try again while waiting on the resolver as well. * ssl: on connection coalescing, do not merge the ssl sessions, as these are frozen post-initialization. * http2: all received GOAWAY frames emit goaway error and teardown the connection independent of the error code (it was only doing it for `:noerror`, but others may appear). * do not check at require time whether the network is multi-homed; instead, defer it to first use and cache (this can break environments which block access to certain syscalls during boot time). * options: do not ignore when user sets `:ip_families` in name resolution.
