fix: browser automation hardening — drag, dialog, select, cookie domain, export alias, X-SQL hint - #576
Conversation
…in, export alias, X-SQL hint - drag: run the synthetic DragEvent sequence in the main world (bypassing JsHandler's isolated world) so page-registered listeners receive the full drag lifecycle; upstream dispatch never reached main-world listeners - dialog: drain DialogHandler's pending queue after dialogAccept/dialogDismiss; the queue was never emptied, so the 'blocked by native dialog' guard kept failing after handled dialogs - select: verify the target element exists before delegating; upstream reported success for missing selectors - cookie domain: normalize leading dot for cookie-set / delete-cookies / state-save (Chrome rejects '.example.com') - export: accept --filename as an alias for --file - X-SQL: append a single-quote hint when H2 misreports a double-quoted CSS selector as a missing column

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR changes dialog cleanup, cookie-domain handling, and HTML snapshot argument precedence. At the current head, dialog cleanup may clear state for dialogs that remain active, invalid cookie domains may still be silently omitted and affect cookie scope, and --filename can lose to a positional filename. These are bounded but concrete correctness risks, so merge should wait for fixes or explicit owner acceptance. Sequence Diagram(s)sequenceDiagram

FetchTask.nRetries was never incremented anywhere, so a context-pool exhaustion PrivacyException turned into an infinite crawlRetry loop (observed: swarm jobs retrying every 30-40s forever). Increment nRetries and fail the task after fetch.maxPrivacyRetries (default 5) attempts instead of retrying indefinitely.

Review：CLI 编译失败（Critical）+ CI 未执行 + 若干文档/覆盖问题
结论：当前 head（3bf09bd0e5）不可 merge。 已检出 head 实测验证。
🔴 Critical — CLI 编译失败
cargo test --bin browser4-cli 报 E0061 ×2：build_command_args 签名变更后 main.rs:15749/16797 未同步（见 args.rs 行内评论）；且 aliases 参数没有任何调用点传入，最后一条 commit 的「alias-aware positional guard」实际未接线，--filename 修复目标尚未达成。PR 描述称「locally built and verified」，但 head 无法编译，推测是在最后一笔 commit 之前验证的。
🟠 CI 未执行（本 PR 无任何 GitHub CI 证据）
「PR Quality Gate」（pr.yml）对本 PR 的全部 8 次 run 均为 action_required + 0 job + 无日志——fork PR（0xsline/Browser4）触发的 gate 不会真正执行（同仓库分支的 PR，如 #572，gate 正常 SUCCESS）。本 PR 目前唯一通过的检查是 CodeRabbit，且没有任何人肉 review。合并前需要：维护者本地全量构建（Rust + Maven）验证，或先修复 fork PR 的 gate 触发问题（项目层面）。
🟡 其余发现（均有行内评论）
- Browser4WebDriver.kt drag 段首注释声称 real CDP drag，与实现（main world 合成 DragEvent）不符。
- commands.rs
normalize_cookie_domaindoc 注释重复两份。 - main.rs
_invalid_domain校验列表（5 命令）与哨兵设置方（3 命令：cookie-list/set/delete）不一致。
🟡 测试缺口（DoD）
Kotlin 侧 drag / dialog drain / select 预检 / privacy 重试上限 / FetchResult / X-SQL hint 均无测试，不符合 Definition of Done「New/changed logic has tests (main path + edge case)」。privacy 重试计数（nRetries 跨重试语义、fetch.maxPrivacyRetries 上限边界）尤其值得单测。
✅ 肯定
- Kotlin 侧 5 个受影响模块（browser4-browser / agentic / rest / skeleton / protocol）在 pulsar-browser 4.11.5 下编译通过。
- drag 的 main-world 派发方向正确，KDoc 如实记录了
isTrusted=false的浏览器级限制；dialog drain、select 预检、X-SQL hint 逻辑本身合理，CodeRabbit 三轮意见均已处理。
Review submitted by mistake; findings are being delivered off-platform. Apologies for the noise.
build_command_args gained an `aliases` parameter but the two call sites in
main.rs were not updated, so the CLI failed to compile:
error[E0061]: this function takes 3 arguments but 2 arguments were supplied
--> src\main.rs:15749:28
--> src\main.rs:16797:18
Wire the shared COMMAND_ARG_ALIASES mapping ("file" -> ["file", "filename"])
into both call sites. This also activates the alias-aware positional guard
from the previous commit: an explicit `--filename` now truly beats a
positional file argument for `htmlsnapshot export` (previously the mapping
was never passed, so the guard was dead code).
Verified: cargo test --bin browser4-cli (1048 passed, 0 failed).
… domain check scope - commands.rs: drop the duplicated normalize_cookie_domain doc comment (kept the trim-aware version). - Browser4WebDriver.kt: rewrite the drag section comment to match the implementation — main-world synthetic DragEvents (isTrusted=false), not a "real CDP drag" as the old comment claimed. - main.rs: narrow the _invalid_domain early-validation to the three commands that actually set the sentinel (cookie-set/cookie-delete/ cookie-list); state-save/state-load accept no --domain option. Verified: cargo test --bin browser4-cli (1048 passed, 0 failed).

Summary
Six small fixes across the CLI (Rust) and backend (Kotlin), all locally built and verified against a real Browser4 runtime. Each fix follows the project's existing pattern of extending
Browser4WebDriver(the documented extension point) and the tool/CLI layers.Fixes
1.
dragnever reached page listeners (Browser4WebDriver)Upstream
drag()dispatches synthetic DragEvents throughJsHandler.evaluate, which runs in an isolated world — the events never reach main-world page listeners, so HTML5 drag-and-drop silently did nothing while reporting success. This override runs the same event sequence throughBrowserProtocol.evaluate(main world) with an async, paced lifecycle (dragstart → dragenter → dragover → drop → dragend).Verified with a live listener probe: full event chain received (dragend observed in document.title).
Known limitation (documented in code): synthetic events are
isTrusted=false, so libraries that gate on isTrusted (SortableJS, react-dnd) still won't respond — that requires native browser drag, which headless CDP input does not start in this driver.2. Dialog state desync (Browser4WebDriver)
dialogAccept/dialogDismisscall CDPPage.handleJavaScriptDialogdirectly but never drainDialogHandler's pending queue (onDialogClosedonly logs). The tool-layer "blocked by a native dialog" guard checks that queue, so screenshots/health-checks kept failing on already-handled dialogs until session close. Overrides drain the queue infinally.3.
selectreported success for missing targets (BrowserTabToolExecutor)selectOptionon a non-existent element returned success. Added an existence check before delegating; now raises "Option target not found: ".4. Cookie domain normalization (CLI, commands.rs)
--domain ".example.com"(leading dot) silently failed because Chrome rejects dotted cookie domains. Normalized withtrim_start_matches('.')in all three domain-passing commands:cookie-set,delete-cookies,browser_save_storage_state.5.
htmlsnapshot export --filenamealias (CLI, commands.rs)--filenamewas silently ignored (file landed in the default snapshot dir). Added it as an explicit alias for--file.6. X-SQL double-quote footgun hint (HTMLSnapshotToolExecutor)
H2 treats double quotes as identifier quotes, so a CSS selector written as
DOM_LOAD_AND_SELECT(@url, "a")fails with a confusingColumn "a" not found. X-SQL errors are returned through the response body (statusCode 417), not exceptions — the hint appends a single-quote explanation toresponse.messagewhen that pattern is detected.Verification
All six fixes verified against a locally built runtime (v4.13.8, pulsar-browser 4.11.5): drag event-chain probe, dialog→screenshot sequence, select error, dotted-domain cookie set/delete, export file path, X-SQL hint message. Full command regression (navigation, snapshot, interaction, htmlsnapshot, eval, storage, screenshot, crawl, agent extract) passes with no regressions.
