Against the real daemon right now, every offer 500s, so the extension captures nothing at all — not "falls through to Firefox on a slow path," genuinely nothing, because the extension is waiting on a promise that never resolves with a decision it can act on. This was buried inside D3's stub list ("...`capture.*`") with no flag for how load-bearing it is; called out on its own row now. | `rpc/dispatcher.cpp` | rules table has no matcher yet, no dedup-against-active-tasks, no category-folder resolution | build step 6 | -| **D8** | `capture.getRules` → `-32603`. The extension mirrors this into its own capture policy on connect (docs/05 §4) so the two can never disagree about what should be intercepted; until this returns something real the extension runs with an empty/stale policy. Also buried in D3's list before this pass. | `rpc/dispatcher.cpp` | same rules-engine gap as D7 | alongside D7 | +| ~~D7~~ | **Closed — `capture.offer` is real.** Applies `capture.enabled`/`excludedHosts`/`monitoredExtensions`/`monitoredMimeTypes`/`minSizeBytes` from settings, then the rules table (`store::Rules` + CORE's `vdm::rules::match_rules`/`glob_match` — DAEMON only converts its own stored `proto::Rule` JSON into CORE's plain `vdm::rules::Rule` vocabulary, per that header's own layering note), resolves the category folder (a rule's explicit `categoryId`/`saveDir`, else `store::Categories::guess_by_extension` — the same extension-guess `download.probe`'s `suggestedCategoryId` already used, now shared instead of duplicated), dedupes against active (non-terminal) tasks by exact URL, and on `take` calls `add_one()` — the same path `download.add` itself uses — so a captured download is a real, admitted, persisted task, not a special case. The 750 ms deadline (CLAUDE.md §4 / AGENT-DAEMON.md build step 6) is checked cooperatively between every step via a new `rpc::CaptureDataSource` seam (real impl wraps `store::*`; a test fake can jump its own clock forward to simulate "the store was slow just now" with zero real sleep) — catches the realistic failure mode (several slow steps adding up) though it can't preempt one pathologically stuck single call. Verified against real `veloxd` + `tools/testserver`: a monitored-type offer answers in ~5ms and actually creates + downloads the task; an unmonitored type, an excluded host, a rule-vetoed host, and a second offer for a still-active URL all answer `ignore` with the right `reason`; a bad category save dir surfaces its real `-32011` rather than being swallowed. New `capture_offer_test` covers all of the above plus the deadline itself (two cases, one per "slow" checkpoint), asserting real wall-clock time barely moves even though the fake clock jumped 2 simulated seconds — proof the check reads the injected clock, not a disguised sleep. | `rpc/capture_data_source.hpp`, `rpc/dispatcher.{hpp,cpp}`, `store/rules.{hpp,cpp}`, `store/categories.{hpp,cpp}`, `store/tasks.{hpp,cpp}` | — | done | +| ~~D8~~ | **Closed alongside D7** — `capture.getRules` returns the same settings-backed `enabled`/`monitoredExtensions`/`monitoredMimeTypes`/`minSizeBytes`/`excludedHosts`/`bypassModifier` capture.offer itself reads, so the two can never drift. `rulesVersion` is a constant `1` — there is no persisted revision counter yet (nothing writes `rules.*` outside this process's own lifetime to need one across a restart), and the extension already re-fetches on `event.settings.changed` regardless of what this number does; noted in case a real counter becomes worth adding later. | `rpc/dispatcher.cpp` | `rulesVersion` is a placeholder constant | — | | D1 | Pairing prompt is `EnvAutoApprover` (needs `VELOX_PAIR_AUTO=1`) | `rpc/pairing.hpp`, `main.cpp` | A GUI dialog / `org.freedesktop.Notifications` approver is integration work | Build step 7 (systemd + notifications) | | — | **D1, checked this pass, not attempted:** `libdbus-1-dev` (or `libsystemd-dev` for `sd-bus`) has no headers installed in this build environment — only the runtime `.so`s (`dpkg -l`/`apt-cache policy` confirm `libdbus-1-3` present, `libdbus-1-dev` not, "Candidate" available but not installed). A real notification-backed approver needs one of those linked into `veloxd`, which is a new build dependency for `daemon/CMakeLists.txt` (`find_package`/`pkg_check_modules`) and — since packaging manifests need to know about it too — arguably a decision to surface rather than something to reach for silently mid-session. `PairingApprover::approve()` is also still synchronous by shape (its own doc comment already says so: "the real notification-backed approver will run async and is not this shape") — swapping it for the async pattern this session built for `download.probe` (`rpc::TaskActionPort` + the server-layer deferred-reply special-case) is the right shape once there's a real implementation to justify the churn; reshaping the interface with nothing behind it yet would just be churn. Left `EnvAutoApprover` in place rather than build a fragile hand-rolled D-Bus wire client to avoid the missing headers — a broken pairing approver is worse than an honest stub. | `rpc/pairing.hpp` | missing dev headers + an undiscussed new dependency | once `libdbus-1-dev`/`libsystemd-dev` is available and the dependency is approved | | ~~D2~~ | **Closed** — `download.probe` is real on both transports. It's genuinely async (the engine's probe pool, up to the schema's 30s `x-deadlineMs`) and so cannot fit `VeloxDispatcher::on_download_probe`'s synchronous `HandlerResult` return — `uds_server.cpp`/`ws_server.cpp` special-case `"download.probe"` before the generic `dispatch()`, exactly the way they already special-case `session.hello`/`session.subscribe`, and queue the reply whenever the callback fires. `rpc::TaskActionPort::probe_now` (kept in proto/std terms, no `vdm::net::*`, so `veloxd_rpc` never needs `core/include`'s vdm headers) is what both transports call; `sched::Scheduler::probe_now` is the implementation — builds a `vdm::net::ProbeRequest`, runs it on the engine's probe pool, maps a failure to `-32013 ProbeFailed` (with `data.httpStatus` when there was one), and fills `suggestedCategoryId`/`suggestedSaveDir` with a plain extension match against the categories table (not the real rules engine — that's still D3). Verified live: a real probe answers in ~5ms; a bad host maps to `-32013`; a connection issuing a 10s `slow-loris` probe does not block a second connection's `download.list` (answered in ~1ms) — confirms the async design actually keeps the loop free, not just compiles. | `rpc/task_action_port.hpp`, `rpc/{uds_server,ws_server}.{hpp,cpp}`, `sched/scheduler.{cpp,hpp}` | — | done | diff --git a/daemon/src/rpc/capture_data_source.hpp b/daemon/src/rpc/capture_data_source.hpp new file mode 100644 index 0000000..3735e59 --- /dev/null +++ b/daemon/src/rpc/capture_data_source.hpp @@ -0,0 +1,50 @@ +#pragma once + +// The seam capture.offer's decision logic reads through, instead of touching store::* (or +// the wall clock) directly — the same reasoning as rpc::TaskActionPort: it lets a test +// substitute a fake that reports "the store took a long time just now" by advancing a +// shared fake clock, and assert that capture.offer's deadline check actually bails to +// `ignore` instead of pressing on, without a real sleep anywhere (deterministic, instant). +// +// vdm::rules::Rule (not velox::proto::Rule) on purpose: this is what +// vdm::rules::match_rules consumes directly, so the real implementation is the only place +// that ever converts the stored proto::Rule/JSON shape into CORE's plain vocabulary. + +#include +#include +#include +#include + +#include "vdm/rules/match.hpp" + +namespace velox::daemon::rpc { + +class CaptureDataSource { +public: + virtual ~CaptureDataSource() = default; + + // Read at every checkpoint in the offer's decision pipeline; a fake can advance this + // however it likes (including "jump forward 2 real seconds, instantly") to simulate a + // slow step without ever calling sleep. + virtual std::chrono::steady_clock::time_point now() = 0; + + virtual bool capture_enabled() = 0; + virtual std::vector monitored_extensions() = 0; + virtual std::vector monitored_mime_types() = 0; + virtual std::int64_t min_size_bytes() = 0; + virtual std::vector excluded_hosts() = 0; + + // Enabled rules, in priority order — ready for vdm::rules::match_rules as-is. + virtual std::vector enabled_rules() = 0; + + // "resolve the category folder": a plain extension guess (store::Categories' + // guess_by_extension) when no rule named a category explicitly. + virtual std::string guess_category_id(const std::string& filename) = 0; + virtual std::string category_save_dir(const std::string& category_id) = 0; + virtual std::string default_save_dir() = 0; + + // True if an active (non-terminal) task already targets this exact URL. + virtual bool has_active_duplicate(const std::string& url) = 0; +}; + +} // namespace velox::daemon::rpc diff --git a/daemon/src/rpc/dispatcher.cpp b/daemon/src/rpc/dispatcher.cpp index 7490e33..c29a4b3 100644 --- a/daemon/src/rpc/dispatcher.cpp +++ b/daemon/src/rpc/dispatcher.cpp @@ -1,6 +1,7 @@ #include "rpc/dispatcher.hpp" #include +#include #include #include #include @@ -12,6 +13,7 @@ #include "fs/safepath.hpp" #include "store/categories.hpp" #include "store/queues.hpp" +#include "store/rules.hpp" #include "store/segments.hpp" #include "store/settings.hpp" #include "store/tasks.hpp" @@ -348,15 +350,251 @@ VeloxDispatcher::on_download_add(const proto::DownloadSpec& spec) { return add_one(spec); } -// --- everything else : not implemented until the store and scheduler land ------------- +// --- capture.offer / capture.getRules : D7/D8 ----------------------------------------- + +namespace { + +// host[:port] out of a URL, lowercased.
