Revision history for Punk
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).
