* Add async HTTP client (curl_multi + ASIO) (#918)Stefan Boberg4 days6-269/+1776
| | | | | | | | | | | | | | | | | | | | | | | - Adds `AsyncHttpClient` — an asynchronous HTTP client using `curl_multi_socket_action` integrated with ASIO for event-driven I/O. Supports GET, POST, PUT, DELETE, HEAD with both callback-based and `std::future`-based APIs. - Extracts shared curl helpers (callbacks, URL encoding, header construction, error mapping) into `httpclientcurlhelpers.h`, eliminating duplication between the sync and async implementations. ## Design - All curl_multi state is serialized on an `asio::strand`, safe with multi-threaded io_contexts. - Two construction modes: owned io_context (creates internal thread) or external io_context (caller runs the loop). - Socket readiness is detected via `asio::ip::tcp::socket::async_wait` driven by curl's `CURLMOPT_SOCKETFUNCTION`/`CURLMOPT_TIMERFUNCTION` — no polling, sub-millisecond latency. - Completion callbacks are dispatched off the strand onto the io_context so slow callbacks don't starve the curl event loop. Exceptions in callbacks are caught and logged. ## Files | File | Change | |------|--------| | `zenhttp/include/zenhttp/asynchttpclient.h` | New public header | | `zenhttp/clients/asynchttpclient.cpp` | Implementation (~1000 lines) | | `zenhttp/clients/httpclientcurlhelpers.h` | Shared curl helpers extracted from sync client | | `zenhttp/clients/httpclientcurl.cpp` | Removed duplicated helpers, uses shared header | | `zenhttp/asynchttpclient_test.cpp` | 8 test cases: verbs, payloads, callbacks, concurrency, external io_context, connection errors | | `zenhttp/zenhttp.cpp` | Forcelink registration for new tests |

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ### Security: Input validation & path safety - **Reject local file references by default** in package parsing — only allow when explicitly opted in by the service (`ParseFlags::kAllowLocalReferences`) and validated by an `ILocalRefPolicy` (fail-closed: no policy = rejected) - **`DataRootLocalRefPolicy`** restricts local ref paths to the server's data root via canonical path prefix matching - **Validate attachment hashes** in compute HTTP handlers — decompresses and re-hashes each attachment at ingestion time to reject tampered payloads - **Path traversal validation** for worker descriptions (`pathvalidation.h`) — rejects absolute paths, `..` components, Windows reserved device names, and invalid filename characters - **Harden CbPackage parsing** against corrupt inputs — overflow-safe attachment count, bounds checks on local ref offset/size, graceful failure instead of `ZEN_ASSERT` for untrusted data - **Harden legacy package parser** — reject zero-size binary fields, missing mappers, and optionally validate resolved attachment hashes - **Bounds check in `CbPackageReader::MarshalLocalChunkReference`** — detect when `MakeFromFile` silently clamps offset+size to file size ### Reliability: Lock consolidation & bug fixes - **Consolidate three action map locks into one** (`m_ActionMapLock`) — eliminates deadlock risk from multi-lock ordering, simplifies state transitions, and fixes a race where newly enqueued actions were briefly invisible to `GetActionResult`/`FindActionResult` - **Fix infinite loop in `BaseRunnerGroup::SubmitActions`** when actions exceed total runner capacity — cap round-robin at `TotalCapacity` and default unassigned results to "No capacity" - **Fix `MakeSafeAbsolutePathInPlace` for UNC paths** — `\server\share` now correctly becomes `\?\UNC\server\share` instead of `\?\server\share` - **Fix `max_retries=0`** — previously fell through to the default of 3; now correctly means "no retries" ### New: ManagedProcessRunner - Cross-platform process runner backed by `SubprocessManager` — uses async exit callbacks instead of polling, delegates CPU/memory metrics to the manager's built-in sampler - `ProcessGroup` (JobObject on Windows, process group on POSIX) for bulk cancellation on shutdown - `--managed` flag on `zen exec inproc` to select this runner - Refactored monitor thread lifecycle — `StartMonitorThread()` now called from derived constructors to avoid calling virtual functions from base constructor ### Process management - **Suppress crash dialogs** via `JOB_OBJECT_UILIMIT_ERRORMODE` + `SEM_NOGPFAULTERRORBOX` in both `WindowsProcessRunner` and `JobObject::Initialize` — prevents WER/Dr. Watson modal dialogs from blocking the monitor thread - **CREATE_SUSPENDED → AssignProcessToJobObject → ResumeThread** pattern in `WindowsProcessRunner` — ensures job object assignment before process execution - **Move stdout/stderr callbacks to `Spawn()` parameters** in `SubprocessManager` — prevents race where early output could be missed before callback installation - Consistent PID logging across all runner types ### Test infrastructure - **`zentest-appstub`**: Added `Fail` (configurable exit code) and `Crash` (abort / nullptr deref) test functions - **Compute integration tests**: exit code handling, auto-retry exhaustion, manual reschedule after failure, mixed success/failure queues, crash handling (abort + nullptr), crash auto-retry, immediate query visibility after enqueue - **Package format tests**: truncated header, bad magic, attachment count overflow, truncated data, local ref rejection/acceptance, policy enforcement (inside/outside root, traversal, no-policy fail-closed) - **Legacy package parser tests**: empty input, zero-size binary, hash resolution with/without mapper, hash mismatch detection - **UNC path tests** for `MakeSafeAbsolutePath` ### Misc - ANSI color helper macros (`ZEN_RED`, `ZEN_BRIGHT_WHITE`, etc.) and `ZEN_BOLD`/`ZEN_DIM`/etc. - Generic `fmt::formatter` for types with free `ToString` functions - Compute dashboard: truncated hash display with monospace font and hover for full value - Renamed `usonpackage_forcelink` → `cbpackage_forcelink` - Compute enabled by default in xmake config (releases still explicitly disable)

* hub s3 hydrate improvements (#902)Dan Engelbrecht2026-03-3012-117/+398
| | | | | | | | | | | | | | | | | | | | | | | | - Feature: Added `--hub-hydration-target-config` option to specify the hydration target via a JSON config file (mutually exclusive with `--hub-hydration-target-spec`); supports `file` and `s3` types with structured settings ```json { "type": "file", "settings": { "path": "/path/to/hydration/storage" } } ``` ```json { "type": "s3", "settings": { "uri": "s3://bucket[/prefix]", "region": "us-east-1", "endpoint": "http://localhost:9000", "path-style": true } } ``` - Improvement: Hub hydration dehydration skips the `.sentry-native` directory - Bugfix: Fixed `MakeSafeAbsolutePathInPlace` when a UNC prefix is present but path uses mixed delimiters
* hub resource limits (#900)Dan Engelbrecht2026-03-3017-306/+500
| | | | | | | | | | | | - Feature: Hub dashboard now shows a Resources tile with disk and memory usage against configured limits - Feature: Hub module listing now shows state-change timestamps and duration for each instance - Improvement: Hub provisioning rejects new instances when disk or memory usage exceeds configurable thresholds; limits are disabled by default (0 = no limit) - `--hub-provision-disk-limit-bytes` - Reject provisioning when used disk exceeds this many bytes - `--hub-provision-disk-limit-percent` - Reject provisioning when used disk exceeds this percentage of total disk - `--hub-provision-memory-limit-bytes` - Reject provisioning when used memory exceeds this many bytes - `--hub-provision-memory-limit-percent` - Reject provisioning when used memory exceeds this percentage of total RAM - Improvement: Hub process metrics are now tracked atomically per active instance slot, eliminating per-query process handle lookups - Improvement: Hub, Build Store, and Workspaces service stats sections in the dashboard are now collapsible - Bugfix: Hub watchdog loop did not check `m_ShutdownFlag`, causing it to spin indefinitely on shutdown
* reuse single MinIO instance across s3client integration test (#901)Stefan Boberg2026-03-301-11/+9
| | | Replace doctest SUBCASEs with sequential scoped blocks so the MinIO server is spawned once and torn down via RAII at scope exit, instead of being restarted for every subcase re-entry. Fixes flaky CI on macOS caused by repeated MinIO process start/stop.

| | | | | | | | | | - **Eliminate `<regex>` usage** — Replaced `std::regex`-based URL parsing in `jupiterbuildstorage.cpp` with manual `string_view` parsing. Added `CXXOPTS_NO_REGEX` to disable regex in cxxopts. Includes comprehensive tests for the new URL parser. - **Add missing HTTP response codes** — Added `102`, `103`, `203`, `207`, `208`, `226`, `306`, `421`, `425`, `451` to the enum and reason string lookup. - **Add `ForceColor` support to zen CLI** — Plumbed the `ForceColor` logging option through to the zen client. - **Add `.clangd` config** — Strips MSVC-specific flags clangd can't handle and suppresses noisy clang-tidy checks. - **Generic `fmt::formatter` for `ToString`** — Concept-based formatter that auto-formats any type with a free `ToString()` function, removing the need for per-type specializations. - **Fix OpenSSL dependency** — Changed `zenhorde` to use `openssl3` package on Linux/macOS. - **Add `<cmath>` include** — Missing include in `hyperloglog.h`. - **GCC compile fix** — Moved `static constinit` variable inside lambda in `logging.cpp`.

* remove CPR HTTP client backend (#894)Stefan Boberg2026-03-2712-1623/+13
| | | CPR is no longer needed now that HttpClient has fully transitioned to raw libcurl. This removes the CPR library, its build integration, implementation files, and all conditional compilation guards, leaving curl as the sole HTTP client backend.
* idle deprovision in hub (#895)Dan Engelbrecht2026-03-2734-353/+1093
| | | | | | | | | | | | | - Feature: Hub watchdog automatically deprovisions inactive provisioned and hibernated instances - Feature: Added `stats/activity_counters` endpoint to measure server activity - Feature: Added configuration options for hub watchdog - `--hub-watchdog-provisioned-inactivity-timeout-seconds` Inactivity timeout before a provisioned instance is deprovisioned - `--hub-watchdog-hibernated-inactivity-timeout-seconds` Inactivity timeout before a hibernated instance is deprovisioned - `--hub-watchdog-inactivity-check-margin-seconds` Margin before timeout at which an activity check is issued - `--hub-watchdog-cycle-interval-ms` Watchdog poll interval in milliseconds - `--hub-watchdog-cycle-processing-budget-ms` Maximum time budget per watchdog cycle in milliseconds - `--hub-watchdog-instance-check-throttle-ms` Minimum delay between checks on a single instance - `--hub-watchdog-activity-check-connect-timeout-ms` Connect timeout for activity check requests - `--hub-watchdog-activity-check-request-timeout-ms` Request timeout for activity check requests
* hub instance state refactor (#892)Dan Engelbrecht2026-03-2718-711/+897
| | | | | | - Improvement: Provisioning a hibernated instance now automatically wakes it instead of requiring an explicit wake call first - Improvement: Deprovisioning now accepts instances in Crashed or Hibernated states, not just Provisioned - Improvement: Added `--consul-health-interval-seconds` and `--consul-deregister-after-seconds` options to control Consul health check behavior (defaults: 10s and 30s) - Improvement: Consul registration now occurs when provisioning starts; health check intervals are applied once provisioning completes
* hub async provision/deprovision/hibernate/wake (#891)Dan Engelbrecht2026-03-246-396/+1126
| | | | | - Improvement: Hub provision, deprovision, hibernate, and wake operations are now async. HTTP requests returns 202 Accepted while the operation completes in the background - Improvement: Hub returns 202 Accepted (instead of 409 Conflict) when the same async operation is already in progress for a module - Improvement: Hub returns 200 OK when a requested state transition is already satisfied
