Revision history for Punk 0.17 2026-08-17 - Fixed t/14-futures.t failing on every perl whose Future is older than the one it was developed against - reported by CPAN Testers against 0.16 on 5.20.0, 5.22.2 and 5.24.0 with "Expected __ANON__(Future.pm line 1140) to return a Future". - A route may now be declared as one hashref, with the handler under `cb`: post "/upload" => { cb => "Web::File#create", max_body => 50_000_000 }; instead of the positional form, which is unchanged and stays the one `punk new` generates: post "/upload" => "Web::File#create", { max_body => 50_000_000 }; - New route option { compress => 0 }, which opts a route out of the server response compression Hyperman 0.25 adds. Punk does not compress - that belongs to the write path - so the option is spelled as a plain response header, Content-Encoding: identity, which the server honours and strips. - New `max_body` keyword and per-route { max_body => N }: refuse a request whose CONTENT_LENGTH is over a ceiling, with the same 413 an oversize API operation gets. - Punk::Upload documents what an upload actually costs: it arrives whole in memory before a handler sees it, ->save is a write and not a stream, and `max_body` does not reduce the memory. - SECURITY: the `markdown` mount reflected the request path into the Location header of its canonical 301 (the redirect that strips a trailing slash or a .md suffix). PATH_INFO reaches a PSGI app percent-DECODED, so that echoed bytes the client chose: a decoded CR/LF split the response at any mount point, and at a root mount "//evil.example/" came back as a protocol-relative 301 off the site. Found while fixing the same class of bug in Punk::OAuth2 (CVE-2026-75628). The redirect now only names a path that IS a page - the stripped target is looked up in the page table first - so the only thing it can echo is one of the mount's own keys. Anything else falls through to the 404 it was always going to get. pmd_redirect also stops at the first control byte, in case a mount prefix ever carries one. 0.16 2026-08-17 - New `proxy` keyword: reverse-proxy trust. Behind nginx, an ELB or a CDN, REMOTE_ADDR is the proxys on every request - and because rate_limit's counters live in Hyperman's shared arena they are exact across the whole worker pool, so every client landed in ONE bucket and a limit => 100 rule throttled the entire site at 100/min. block_ip, keyed the same way, it would ban the load balancer. `proxy` resolves the real client at the top of the dispatcher and OVERWRITES REMOTE_ADDR, so rate_limit, block_ip, the access log and $c->req->address are all correct with no change to any of them; the connecting address stays as $c->env->{'punk.peer_addr'}. - New $c->req->address: REMOTE_ADDR, which is the socket peer directly exposed and the resolved client behind `proxy`. 0.15 2026-08-17 - A trailing slash on the request path no longer 404s: GET /account/ answers the route declared as GET /account. The retry runs only after every declared route, API operation and mount has missed, so nothing that already matched changes - a *splat still captures its trailing slash, and a mounted app is still handed the path it was sent, since only it knows whether /docs and /docs/ differ. Repeated slashes collapse, and "/" is left alone. A trimmed path that matches a different method still answers 405 with its Allow list. 0.14 2026-08-16 - Requires from the C layer go through pk_require_once (an %INC check, then at most one eval per module per process) instead of a bare eval_pv per call. Perl's own eval_sv spends immortal references on every call on perls through 5.20 - whatever is evaluated, success or failure - and before 5.20 the immortals' refcounts are small and unprotected, so a path that re-requires per build (the markdown mount ran two) drains PL_sv_undef toward a segfault under punk dev's rebuild loop. Found by t/42-immortal-refcount.t on a CPAN smoker running perl 5.20.0; verified fixed on 5.20.3. - t/37-ua.t pins the per-request agent clones it compares by address: a freed clone's memory is the allocator's to hand straight back, so two DEAD clones can legally compare equal, which a smoker's malloc duly demonstrated. Held alive, distinct objects must differ. 0.13 2026-08-16 - $c->send_file($path_or_scalarref, %opts): a finished download response - Static files inherit the send_file core - The punk command line rebuilt around a registry: commands are specs (abstract, options with docs and defaults, nested verbs, code), and help is generated from them - Plugin subcommands: Punk::Command->register($name => \%spec) with owner-collision croaks; an unknown command gets one require of Punk::Command::, whose load registers it - In-process testing seam: $Punk::Command::OUT/$ERR replace the streams and main() returns the exit code. - routes: --method, --path GLOB, --kind, and --json. - dev: --workers, --watch (repeatable), --env; one watch loop. - console: a history file, --eval 'CODE', and q/exit. - New commands: `generate controller|model` into an existing application 0.12 2026-08-15 - Adds Punk::Auth. The `auth` keyword freezes the config at to_app (model, a fields map so existing schemas need no renames, session_key, roles hook, rank ladder); croaks without a session, on any unknown option, and on a roles target typo - at boot. - Context surface: $c->login / logout / auth_id / current_user (memoized per request, model loaded through an await seam so the blocking DBI backend and the future-returning DBIx::Loop backend both work). - auth_guard for `under`: the bare is-anyone-signed-in form runs entirely in C. Denial negotiates - a browser is redirected to login_path with a relative-only ?to= return-to, an API client gets the house 401 - with on_denied '403', '404' or a coderef. The roles hook may return one role, a list or an arrayref; a required role on the rank ladder means "this or better", one outside it matches exactly (a staff role next to tenant roles). Guards record what they learned in $c->stash->{auth}. - Bare `model;` registers everything under MyApp::Model::* 0.11 2026-08-15 - Security response headers (Punk::Headers): a `headers` keyword freezing a header policy at to_app, applied in C on the way out of the dispatcher. - Content negotiation ($c->respond_to): calls the handler for the most acceptable offered format (json/html/text/xml or a full media type) and returns its response. 0.10 2026-08-15 - Development error pages (Punk::DevError): in development a die renders an HTML debug page - The environment now defaults to production; development is an opt-in: punk dev sets PUNK_ENV=development for its server, or set it yourself in the Env. - Punk::Validate: request validation, all in C on the JSON::Schema::Fast C ABI. $c->validate($schema) collects into a Result - errors in the Open::API shape plus name, valid() hands back typed filtered params - and a bare $c->validate reads the Result a route-level check stashed. Routes take an options hashref: get '/x' => $target, { validate => \%schema } (or { schema, source, on_invalid }), compiled once at to_app and run as a C guard after any auth guards; failures answer the OpenAPI-mount-shaped 400 or the on_invalid target. - New on_not_found keyword: the on_error contract for a 404 so you can return a custom response - The getentropy probe now links instead of only compiling. FreeBSD before 12 has no getentropy and its old compilers take the implicit declaration as a warning, so 0.09's compile-only probe false-positived and the .so failed to load with "Undefined symbol getentropy". 0.09 2026-08-15 - Adds Punk::Test, Punk::Test::WS and Punk::Test::WS::Conn - Flash messages, in C (punk_flash.h): $c->flash and $c->flash_keep over the session's reserved punk.flash key. 0.08 2026-08-14 - t/42-immortal-refcount.t failed the distribution on perl 5.18, where perl itself moves the refcount it measures. Before 5.20 av_extend filled the slots it allocated with &PL_sv_undef and av_undef released every slot up to the fill. 0.07 2026-08-13 - The router stored &PL_sv_yes bare in three set-membership hashes - New PUNK_SET_TRUE (include/punk/punk_compat.h) is the sanctioned way to put a true value in a set slot - it takes the reference first, so the container has one to spend, with no allocation. 0.06 2026-08-13 - Rate limiting and IP blocking over Hyperman's shared arena (requires Hyperman 0.18, ABI v3; fails open without it). - New `rate_limit` keyword: installs a before_dispatch that answers 429 (with Retry-After and the X-RateLimit-* headers) when a caller is over the limit. Key by client IP (default), a request header (by => 'header:X-Api-Key'), or a coderef; scope to a path prefix with `for`. Chainable for layered limits. The counters live in the shared arena, so a limit is exact across the worker pool rather than per worker. - New context methods: $c->block_ip([$ip [, $ttl]]) and $c->unblock_ip([$ip]) add or lift an IP on the edge denylist ($ip defaults to the request's REMOTE_ADDR), and $c->rate_hit for a raw counter check. 0.05 2026-08-12 - Fixed a segfault on perl before 5.20. Six places handed one of perl's immortal SVs to something that would release it. - t/42-immortal-refcount.t asserts the invariant rather than the symptom: an immortal's refcount may not move across these calls. That fails on any perl, including the ones where the bug is invisible. - Update min version of deps 0.04 2026-08-08 - Fixed the configure-time dependency declaration, which is why 0.03 could not be installed from CPAN at all. - $app->install_kw($name => $code, $owner?): a plugin can install a declaration keyword of its own into the application class instead of assigning to a glob there. - params now takes names: `$c->params(@names)` and `$req->params(@names)` return just those, as a list of values in the order asked for, or - in scalar context - a hashref of only the names that were passed. 0.03 2026-08-07 - Punk::Model::DBIx::Loop, a non-blocking model backend. The same six-method contract, the same SQL and the same result shapes as Punk::Model::DBI, but every method returns a Punk::Future and the statement runs on DBIx::Loop over the worker's own event loop. - It runs on DBIx::Loop's C ABI (dbil_abi.h, via ExtUtils::Depends) - Fixed Punk::Model's delegation returning the caller's own arguments alongside the backend's result. - Punk::Model::DBI is ~40% faster per statement: quote_identifier and the fixed-shape get/delete SQL are memoised on the pooled connection instead of rebuilt every call. A get is 2.05us against 3.61us. The table is part of the statement cache key - the cache is shared by every model on a dsn. - Add the `markdown` mount/keyword: point it at a nested directory of .md files and get a documentation site. Navigation reflecting the tree, a per-page table of contents from the headings, syntax highlighting, ranked search, and the images sitting alongside the markdown served as static files. - The site is built at boot. The tree is walked, every page is rendered through Markdown::Simple and wrapped by Template::Stencil, the search index is filled, and the finished bytes are frozen. A request is then a hash lookup and a triplet, with no markdown parse, no template render and no Perl frame. `reload => 1` re-renders a page whose source has changed, for the edit loop under `punk dev`. - Refactor the stat / conditional-request / sendfile half of punk_static.h out as ps_serve_file, so the markdown mount serves the assets in its tree through the same code rather than a second implementation that would drift from it. 0.02 2026-08-06 - $c->ua: an outbound HTTP agent on the context - The agent is one per worker, not one per request: it owns a keep-alive pool and its DNS state. - More than one agent: `ua partner => { ... }` names a second, the same shape `database` uses for a second database, and $c->ua('partner') asks for it. - Needs Fetch 0.11 for the per-request jar (Fetch->clone). 0.01 2026-08-06 First version
