* ✨ Add font processing resource limits via prlimit
Font processing tools (fontforge, sfnt2woff, woff2sfnt, woff2_decompress)
were invoked via clojure.java.shell/sh with no timeouts or resource limits.
This adds process-level resource limits using prlimit(1) and the shell/exec!
infrastructure from the ImageMagick hardening work.
shell/exec! changes:
- Add :prlimit parameter that prepends prlimit(1) to the command
- :prlimit takes {:mem <MiB> :cpu <seconds>} for address space and CPU time
limits, enforced by the kernel's RLIMIT subsystem
- prlimit-cmd builds the prlimit command prefix (private helper)
Font processing changes:
- Replace all clojure.java.shell/sh calls with shell/exec! via exec-font!
- exec-font! applies font-prlimit (512 MiB, 30s CPU, 60s wall-clock)
- All 5 conversion functions (ttf->otf, otf->ttf, ttf-or-otf->woff,
woff->sfnt, woff2->sfnt) use try/finally for explicit temp file cleanup
- Remove clojure.java.shell require from media.clj
Tests:
- Add exec-prlimit-normal, exec-prlimit-cpu, exec-prlimit-memory tests
Closes#10234

* ✨ Make font processing resource limits configurable
Replace hardcoded font-prlimit map and wall-clock timeout with
config-driven values under the PENPOT_FONT_PROCESS_* namespace.
The prlimit implementation detail is not exposed in config keys.

* 🐳 Add ImageMagick policy.xml resource limits to backend Docker image
Add a restrictive policy.xml to the backend Docker image that caps
ImageMagick resource usage: 256MiB memory, 512MiB map, 128MP area,
30s time limit, 16KP max dimensions. Blocks PS/EPS/PDF/XPS coders
to prevent Ghostscript attack surface.

* ✨ Add timeout support to shell/exec!
Add optional :timeout parameter (in seconds) that uses
Process.waitFor(long, TimeUnit). On timeout, the process is
destroyed forcibly and an :internal/:process-timeout exception
is raised. Stdout/stderr readers handle IOException from closed
streams when the process is killed.

* ♻️ Rename ::wrk/netty-executor to ::wrk/executor with cached pool
Replace DefaultEventExecutorGroup (fixed Netty thread pool) with a
cached thread pool (px/cached-executor) for general async task
offloading. The cached pool creates threads on demand and reuses
idle ones, which is more appropriate for blocking I/O workloads
(shell commands, message bus, rate limiting, etc.).
Changes:
- Rename ::wrk/netty-executor to ::wrk/executor in worker/executor.clj
- Switch implementation from DefaultEventExecutorGroup to px/cached-executor
- Update all ig/ref wiring in main.clj (msgbus, tmp cleaner, climit, rlimit, rpc)
- Remove ::wrk/netty-executor from redis.clj (let lettuce create its own
eventExecutorGroup instead of sharing a Netty executor)
- Assert executor is present in shell/exec! to prevent silent nil usage
- Remove executor-threads config (no longer needed for cached pool)
The ::wrk/netty-io-executor (NioEventLoopGroup) remains unchanged as it
handles actual non-blocking network I/O for Redis and S3.

Add :uri and :scheme/:host keys to exceptions raised by
`validate-uri` for better error diagnostics. Also fix a bug
where (str url) was used instead of (str uri) in the
host-missing exception path.
Update the existing blocked-target test to verify the new :uri
key, and add three new tests covering scheme rejection, missing
host, and DNS failure error paths. All 27 tests pass with 60
assertions and 0 failures.

* 🎉 Add telemetry anonymous event collection
Rewrite the audit logging subsystem to support three operating modes and
add anonymous telemetry event collection:
Modes:
- A (audit-log only): events persisted with full context
- B (audit-log + telemetry): same as A, plus events are collected for
telemetry shipping
- C (telemetry-only): events stored anonymously with PII stripped,
telemetry flag active, audit-log flag inactive
Audit system refactoring (app.loggers.audit):
- Replace qualified map keys (::audit/name etc.) with plain keywords
- Rename submit! -> submit, insert! -> insert, prepare-event ->
prepare-rpc-event
- Add submit* as a lower-level public API
- Add process-event dispatch function that handles all three modes and
webhooks in a single tx-run!
- Add :id to event schema (auto-generated if omitted)
- Add filter-telemetry-props: anonymises event props per event type.
Keeps UUID/boolean/number values; for login/identify events preserves
lang, auth-backend, email-domain; for navigate events preserves route,
file-id, team-id, page-id; instance-start trigger passes through.
- Add filter-telemetry-context: retains only safe context keys.
Backend: version, initiator, client-version, client-user-agent.
Frontend: browser, os, locale, screen metrics, event-origin.
- Timestamps truncated to day precision via ct/truncate for telemetry
storage
- PII stripped: props emptied, ip-addr zeroed, session-linking and
access-token fields removed from context
Config (app.config):
- Derive :enable-telemetry flag from telemetry-enabled config option
Email utilities (app.email):
- Add email/clean and email/get-domain helper functions for domain
extraction from email addresses
Setup (app.setup):
- Emit instance-start trigger event at system startup
- Simplify handle-instance-id (remove read-only check)
RPC layer (app.rpc):
- wrap-audit now activates when :telemetry flag is set
- Add :request-id to RPC params context for event correlation
RPC commands (management, teams_invitations, verify_token, OIDC auth,
webhooks): migrate all audit call sites to use the new plain-key API
SREPL (app.srepl.main):
- Migrate all audit/insert! calls to audit/insert with plain keys
Telemetry task (app.tasks.telemetry):
- Restructure legacy report into make-legacy-request; distinguish
payload type as :telemetry-legacy-report
- Add collect-and-send-audit-events: loop fetching up to 10,000 rows
per iteration, encodes and sends each page, deletes on success,
stops immediately on failure for retry
- Add send-event-batch: POSTs fressian+zstd batch (base64 via
blob/encode-str) to the telemetry endpoint with instance-id per event
- Add gc-telemetry-events: enforces 100,000-row safety cap by dropping
oldest rows first
- Add delete-sent-events: deletes successfully shipped rows by id
Blob utilities (app.util.blob):
- Add encode-str/decode-str: combine fressian+zstd encoding with URL-
safe base64 for JSON-safe string transport
Database:
- Add migration 0145: index on audit_log (source, created_at ASC) for
efficient telemetry batch collection queries
Frontend:
- Always initialize event system regardless of :audit-log flag
- Defer auth events (signin identify) to after profile is set
- Refactor event subsystem for telemetry support
Tests (21 test vars, 94 assertions in tasks-telemetry-test):
- Cover all code paths: disabled/enabled telemetry, no-events no-op,
happy-path batch send and delete, failure retention, payload anonymity,
context stripping, timestamp day precision, batch encoding round-trip,
multi-page iteration, GC cap enforcement, partial failure handling
- blob encode-str/decode-str round-trip tests (14 test vars)
- RPC audit integration tests (5 test vars)

The current binfile export process uses a streaming technique. The
major problem with the streaming approach is the case when an error
happens on the middle of generation, because we have no way to
notify the user about the error (because the response is already
is sent and contents are streaming directly to the user
client/browser).
This commit replaces the streaming with temporal files and SSE
encoded response for emit the export progress events; once the
exportation is finished, a temporal uri to the exported artifact
is emited to the user via "end" event and the frontend code
will automatically trigger the download.
Using the SSE approach removes possible transport timeouts on export
large files by sending progress data over the open connection.
This commit also removes obsolete code related to old binfile
formats.
Replace general usage of virtual threads with platform threads
and use virtual threads for lightweight procs such that websocket
connections. This decision is made mainly because virtual threads
does not appear on thread dumps in an easy way so debugging issues
becomes very difficult.
The threads requirement of penpot for serving http requests
is not very big so having so this decision does not really affects
the resource usage.
This upgrade also includes complete elimination of use spec
from the backend codebase, completing the long running migration
to fully use malli for validation and decoding.
This commit also comes with:
- a fix for incorrect conflict handling on team access request creation
- a fix for incorrect handling of file-data when it is offloaded
- replace some inneficient queries with effcient ones
- remove redundant validation on creation of request-access
this allows almost all api operations to success usin application/json
encoding with the exception of the update-file, which we need to
approach a bit differently;
the reason update-file is different, is because the operations vector
is right now defined without the context of shape type, so we are just
unable to properly parse the value to correct type using the schema
decoding mechanism
Also optimizes some functions for faster shape and rect props
access (there is still a lot of work ahead optimizing the rest of
the functions)
Also normalizes shape creation and validation for ensuring
correct setup of all the mandatory properties.
