[ruby-talk:444332] [ANN] httpx 0.24.6 released
by Tiago Cardoso 28 Sep '23

28 Sep '23

httpx 0.24.6 has been released. NOTE: If nothing significant happens, this will be the last release before v1 is released (which should happen during next week). ``` 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 * Datadog integration * Faraday integration * Webmock integration * Sentry integration Here are the updates since the last release: # 0.24.6 ## Bugfixes * fix Session class assertions not prepared for class overrides, which could break some plugins which override the Session class on load (such as `datadog` or `webmock` adapters). # 0.24.5 ## Bugfixes * fix for SSL handshake post connection SAN check using IPv6 address. * fix bug in DoH impl when the request returned no answer. # 0.24.4 ## Improvements * `digest_authentication` plugin now supports passing HA1hashed with password HA1s (common to store in htdigest files for example) when setting the`:hashed` kwarg to `true` in the `.digest_auth` call. * ex: `http.digest_auth(user, get_hashed_passwd_from_htdigest(user), hashed: true)` * TLS session resumption is now supported * whenever possible, `httpx` sessions will recycle used connections so that, in the case of TLS connections, the first session will keep being reused, thereby diminishing the overhead of subsequent TLS handshakes on the same host. * TLS sessions are only reused in the scope of the same `httpx` session, unless the `:persistent` plugin is used, in which case, the persisted `httpx` session will always try to resume TLS sessions. ## Bugfixes * When explicitly using IP addresses in the URL host, TLS handshake will now verify if the IP address is included in the certificate. * IP address will keep not being used for SNI, as per RFC 6066, section 3. * ex: `http.get("https://10.12.0.12/get")` * if you want the prior behavior, set `HTTPX.with(ssl: {verify_hostname: false})` * Turn TLS hostname verification on for `jruby` (it's turned off by default). * if you want the prior behavior, set `HTTPX.with(ssl: {verify_hostname: false})` # 0.24.3 ## Improvements * faraday adapter: reraise httpx timeout errors as faraday errors. * faraday adapter: support `:bind` option, which expects a host and port to connect to. ## Bugfixes * faraday adapter: fix `#close` implementation using the wrong ivar. * faraday adapter: fix usage of `requestt_timeout` translation of faraday timeouts into httpx timeouts. * faraday adapter: `ssl: { verify: false }` was being ignored, and certification verification was still proceeding. # 0.24.2 ## Improvements * besides an array, `:resolver_options` can now receive a hash for `:nameserver`, which **must** be indexed by IP family (`Socket::AF_INET6` or `Socket::AF_INET`); each group of nameservers will be used for emitting DNS queries of that iP family. * `:authentication` plugin: Added `#bearer_auth` helper, which receives a token, and sets it as `"Bearer $TOKEN` in the `"authorization"` header. * `faraday` adapter: now implements `#build_connection` and `#close`, will now interact with `faraday` native timeouts (`:read`, `:write` and `:connect`). ## Bugfixes * fixed native resolver bug when queries involving intermediate alias would be kept after the original query and mess with re-queries. # 0.24.1 ## Improvements * datadog adapter: support `:service_name` configuration option. * datadog adapter: set `:distributed_tracing` to `true` by default. * `:proxy` plugin: when the proxy uri uses an unsupported scheme (i.e.: "scp://125.24.2.1"), a more user friendly error is raised (instead of the previous broken stacktrace). ## Bugfixes * datadog adapter: fix tracing enable call, which was wrongly calling `super`. + `:proxy` plugin: fix for bug which was turning off plugins overriding `HTTPX::Connection#send` (such as the datadog adapter).

[ruby-talk:444327] [ANN] Learning by Reversing: Native Gems, Part 6
by Mohit Sindhwani 27 Sep '23

27 Sep '23

Hi Everyone, I started on a series to learn by reversing a simple native C Ruby gem. Part 6 is now published! It looks at how to benchmark the native gem. Link to Part 6: https://notepad.onghu.com/2023/learning-by-reversing-s1-e6-native-gems/ The whole series is available at: https://notepad.onghu.com/2023/learning-by-reversing-s1-native-gems/ * Part 1 - This covers the background to the gem we explore Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e1-native-gems/ * Part 2 - This goes into the details of how ruby loads the native gem and extension (and includes a nice sequence diagram of how all the bits happen together) Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e2-native-gems/ * Part 3 - How do we ensure that we have everything and that it actually gets built at installation? Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e3-native-gems/ * Part 4 - Understanding the development Makefil Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e4-native-gems/ * Part 5 - The Ruby C/API Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e5-native-gems/ There are more parts planned, including documenting the code, running the specs and enhancing the gem. Comments on the posts or the plans welcome. I'm @onghu on Twitter or @onghu@ruby.social on Mastodon if you're on either. Best regards, Mohit.

[ruby-talk:444323] [ANN] minitest 5.20.0 Released
by Ryan Davis 06 Sep '23

06 Sep '23

minitest version 5.20.0 has been released! * home: <https://github.com/minitest/minitest> * bugs: <https://github.com/minitest/minitest/issues> * rdoc: <https://docs.seattlerb.org/minitest> * vim: <https://github.com/sunaku/vim-ruby-minitest> * emacs: <https://github.com/arthurnn/minitest-emacs> minitest provides a complete suite of testing facilities supporting TDD, BDD, mocking, 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/mock by Steven Baker, is a beautifully tiny mock (and stub) object framework. 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: ### 5.20.0 / 2023-09-06 * 1 minor enhancement: * Optionally allow autorun exit hook to remain active in forked child. (casperisfine)

[ruby-talk:444322] [ANN] zenweb 3.10.8 Released
by Ryan Davis 30 Aug '23

30 Aug '23

zenweb version 3.10.8 has been released! * home: <https://github.com/seattlerb/zenweb> * bugs: <https://github.com/seattlerb/zenweb/issues> * rdoc: <http://docs.seattlerb.org/zenweb> Zenweb is a set of classes/tools for organizing and formating a website. It is website oriented rather than webpage oriented, unlike most rendering tools. It is content oriented, rather than style oriented, unlike most rendering tools. It uses a rubygems plugin system to provide a very flexible, and powerful system. Zenweb 3 was inspired by jekyll. The filesystem layout is similar to jekyll's layout, but zenweb isn't focused on blogs. It can do any sort of website just fine. Zenweb uses rake to handle dependencies. As a result, scanning a website and regenerating incrementally is not just possible, it is blazingly fast. Changes: ### 3.10.8 / 2023-08-30 * 1 bug fix: * Fixed configuration of no_line_numbers for kramdown v2 changes

Hello, Is () supposed to allow multiple statements in it? Documentation is not explicit about it. https://docs.ruby-lang.org/en/master/syntax/control_expressions_rdoc.html#l… E.g. puts((:ignore; :x)) # x puts (:ignore; :x) # Otoh, raises an unexpected semicolon error I'm looking at using () in a while loop's condition but please just consider that as an extra info. I need an official answer on my query above. -- konsolebox
