Revision history for Punk

0.23    2026-08-20
        - ADDS: Punk::Plugin::Sitemap sitemap.xml/robots.txt
        - ADDS: static mounts can say how fresh a file is. `max_age`
          and `cache_control` set Cache-Control on a plain URL, and
          $c->send_file takes cache_control too.
        - ADDS: content-addressed asset URLs. $c->asset('/static/app.css')
          returns /static/app.9f3a1c2b0d4e5f60.css. The digest - the first 8
          bytes of SHA-256 over the contents. 
        - ADDS: Punk::Plugin::RequestId per request identifier

0.22    2026-08-20
        - ADDS: Punk::Plugin::Sitemap, phase 1 - which of an
          application's routes are actually URLs. Punk compiles every
          route at boot, so the application already holds a complete
          list of what it serves, and a sitemap is that list with a
          filter over it. A route is listed only when it is a GET, its
          path holds no capture, it carries no guard, and it did not opt
          out. Out is the safe direction: a page missing from a sitemap
          is still crawled if anything links to it, while a page wrongly
          present is a crawler fetching a 404 or a login redirect on a
          schedule.
          The part a hand-written sitemap cannot do: a page behind a
          guard is excluded WITHOUT anyone maintaining a list, because
          `under($prefix, $guard)` copies its guard chain into every
          route declared inside it and the plugin reads it off the
          record.
          `base` is required and is configuration. The protocol wants
          absolute URLs, and taking the host from the request would let
          `Host: evil.example` produce a sitemap naming that host for
          every page on the site - delivered to search engines, and
          invisible to the owner, whose own request produces a correct
          file.
          New route option: `sitemap => 0` keeps a route out, and
          `sitemap => 1` puts one in despite a guard, because a scope
          guard may be an authentication check or an ordinary filter and
          Punk cannot read which. The method and the shape are not
          overridable - sitemap => 1 on a POST or on /users/:id is a
          mistake rather than an instruction.
          Rendering, dynamic sections and robots.txt are phases 2 to 4;
          the plan is in plan_punk_sitemap/.
        - FIX: change abi version checks from == to <=
        - Adds: Punk::Cache, Punk::Cache::Memory and Punk::Cache::File

0.21    2026-08-20
        - FIX: A Punk::WebSocket::Room now reaches the whole pool.
        - FIX: SSE also now works correctly accross workers.
        - ADDS: $c->publish and $c->subscribe hyperman event bus hooks

0.20    2026-08-19
        - The dynamic-route path no longer requires Open::API. It
          checked that api_mounts EXISTED rather than that it held
          anything, and api_mounts is always present in the compiled
          state - so an app that never declared an `api` still reached
          the API branch on any route that was not a static hit, and
          croaked there when Open::API's C ABI did not match.
        - Punk publishes a C ABI of its own, pk_abi.h, installed through
          ExtUtils::Depends and reached at runtime through
          Punk::_abi_ptr. 

0.19    2026-08-18
        - SECURITY: a session had no server-side lifetime. `expires` set
          only the cookie's Max-Age, which is a request to a client that
          is free to ignore it - the signature carried no time at all, so
          a cookie captured once (a shared machine, a log, a backup, a
          proxy) stayed valid for as long as the secret did, and
          session_expire only asked the browser to forget a value that
          still authenticated. The expiry is now stamped inside the signed payload
        - New $c->safe_path($path, $fallback?): returns the path when it
          is same-origin and relative, otherwise the fallback. Punk had
          no such guard while auth_guard hands every application a ?to=
          to redirect to, which made the obvious login form an open
          redirect. Same rules as Punk::OAuth2's same_origin_path, for
          the same reasons (CVE-2026-75628)
        - The static traversal guard splits segments on a backslash as
          well as a slash. On POSIX "..\.." is one ordinary filename and
          traverses nothing, but Windows reads it as a separator, so a
          guard that split on "/" alone saw one harmless segment where
          the OS would see two levels up. 
        - New hook phase `before_request`, which runs BEFORE routing:

            hook before_request => sub {
                my ($c) = @_;
                $c->stash->{t0} = Time::HiRes::time();
                return;
            };

          The earliest phase until now was before_dispatch, which runs
          only after the router has matched - so nothing could observe a
          request from its start, and nothing ran at all for a 404, a
          405, or anything answered by a PSGI or static mount.
          before_request runs for all of those.
        - The logger takes a record: a lone unblessed hashref is a set of
          fields, and its `message` key is the message.

            $c->log->info({ message => 'listing books',
                            books => 12, user => $id });

0.18    2026-08-18
        A security release. issue reported by CPANSec.
        - SECURITY (CVE-2026-75870): `session` declared without a secret
          signed the cookie with an EMPTY HMAC key. The keyword froze
          whatever options it was given without requiring a secret,
          warning, or refusing to start, and both the cookie read and the
          write-back defaulted that key to "". a secret is now required

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::<Ucfirst>, 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).
