Implements the standalone batch geoprocessing runner gp.batch in crates/engine/src/cmd/gp.rs, fulfilling the roadmap item in ROADMAP.md under Underway ("Batch runs: one tool over many layers or a folder of files", #1458).
gp.batch complements gp.run by executing any registered geoprocessing tool over an array of layers, file paths, a wildcard selector ("*"), or an entire directory folder of vector files in an atomic, fault-tolerant run.
Comparison: Single Processing (gp.run) vs. Batch Processing (gp.batch)
Dimension
Single Processing (gp.run)
Batch Processing (gp.batch)
Command ID
gp.run
gp.batch
Primary Goal
Run a single geoprocessing tool on one layer or table.
Execute one tool repeatedly across multiple project layers, file paths, or a directory folder of datasets.
Target Specification
Fixed: params: {"input": "Cities", ...}
Dynamic: inputs: ["Cities", "Rivers"] or folder: "data/raw/"
Parameter Binding
Caller must explicitly name the input parameter (input, target, polygons).
Smart auto-binding: detects the tool's primary layer parameter or accepts custom param / batch_param.
Failure Semantics
Fail-Fast: Returns Err(msg) immediately on any error.
Isolated Fault Tolerance ("Never Crash, Never Silent"): Executes each item in an isolated boundary. If layer $k$ fails, logs a notification, records the error, and continues with items $k+1 \dots N$.
Progress Reporting
Single-item progress (0%–100% of rows/vertices).
Passes Control to each running tool for step progress; returned JSON and notices report aggregate total, succeeded, and failed.
Cancellation
Synchronous on Session; UI background runs use tool_start + Control.
Synchronous on Session; run_batch_with accepts an Arc<Control> allowing cooperative cancellation across items for programmatic callers and tests.
Output Naming
Defaults to static tool name ("Buffer"). Multiple runs risk layer name collision.
Logs each individual run into Session.project.gp_history plus notifies a consolidated summary ("Batch 'buffer' complete: 2 succeeded, 1 failed").
Platform Portability
Runs on Desktop, CLI, and WebAssembly.
Project layer batching (inputs: [...] or inputs: "*") works on Desktop, CLI, and WASM. File directory iteration (folder: "...") is gated desktop-only (#[cfg(not(target_arch = "wasm32"))]).
File Access Classification (Reach::Files): Because gp.batch can read datasets from disk in the current working directory, all explicit inputs (layer names or file paths) and folder specifications are classified as file access (Reach::Files), prompting for confirmation in the AI Assistant and restricted in imported tasks without file permissions.
In-Memory Operations: A wildcard run (inputs: "*") is file access only when the tool reads files through a Path or VectorLayers parameter or runs a GeoLibre program; otherwise it runs over the active map's layers without file access. Tools that write files are refused.

Run a geoprocessing tool across named layers, all vector layers on the active map, or supported files in a folder on native builds. Folder inputs are processed alphabetically.
Batch runs continue after individual failures and report successful and failed inputs, output names, and relevant errors. A run succeeds if at least one input completes; if all inputs fail, the errors are reported.
Batch runs can be replayed from history.
Table outputs are added without replacing existing tables by default; name collisions receive numbered suffixes.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
This change adds gp.batch to run one geoprocessing tool across selected layers or files. It adds batch result handling, file-access classification, and history replay support. It also documents batch behavior, updates project status, and exposes accepted parameter-name checks for analysis tools.
Changes: Batch geoprocessing
Layer / File(s)
Summary
Batch command setup and inputs crates/engine/src/cmd/gp.rs
gp.batch validates options and shared parameters, selects inputs from named layers, active-map vector layers, or native folders, and checks output patterns.
Per-input execution and results crates/engine/src/cmd/gp.rs
The command runs each input with cancellation handling, tracks outputs and failures, records history, and returns aggregate results. Tests cover input selection, output naming, file loading, warnings, replay, cancellation, and cleanup.
Tool results and table outputs crates/engine/src/cmd/gp.rs
Shared tool execution supports configurable notices and table replacement. It handles table-name collisions, custom history data, and messages from file-queue operations.
File-access checks include batch inputs and parameters, and history replay accepts gp.batch records. The guide describes batch options, results, and access rules. Project status documents mark batch runs as underway and available.
The analysis crate exports aliases for joinField parameters. is_accepted_param checks declared parameter names and accepts those aliases for joinField.

A rabbit watches layers flow, Then batches tools in rows, It names each output as it lands, And gathers warnings, counts, and plans, With every run, the records grow.
Layer names with a dot are truncated.file_stem runs on layer names too, so Roads.2020 becomes Roads_buffer, and Roads.2020 and Roads.2021 collide. (gp.rs:1073, confidence high)
Output names can collide, and the batch still reports success. A pattern without {input}, or two inputs with the same stem, gives duplicate layer names. Line 1079 also silently overwrites a caller's params.output. (gp.rs:1074, confidence medium)
Possible approval-gate bypass.inputs_of now reads files for single-layer params, but reads_files still only covers Path and VectorLayers. The assistant's gate therefore does not see {"tool":"buffer","params":{"input":"roads.geojson"}} as file access. (gp.rs:771, confidence medium, from reading plugins.rs:357 and items.rs:817; I did not run it)
Security
No findings. gp.batch is gated for the assistant because its spec contains "folder", which is in PLACE_KEYS.
Performance
No cap on the number of batch items; a large folder runs every file in one call. Low severity.
Quality
Unrelated doc rewrites, and they contradict the code.analysis.md documents <input>_Validation and a status schema, but check_geometry.rs:62 writes <input>_check. It also documents fixGeometries, which exists nowhere in crates/, removes the raster.rasterize section even though that code exists, and reworded the work-limit text. (analysis.md:860, confidence high; table row at :161)
Silent folder skips. Unsupported extensions, unreadable entries, and an ignored folder when inputs is also given produce no notice. (gp.rs:1036, confidence high)
Help text and docs disagree on the parameter name. The spec says outputPattern, while the docs and tests use output_pattern. Both are accepted, so pick one.
The "*" wildcard includes table layers, but the docs say "every vector layer".
AGENTS.md
One notice per failure. Each failed item calls notify, so 500 bad files give 500 notices. It should be one notice with a count. (gp.rs:1097, confidence high)
Missing "test both ways" coverage. There is no test for the folder skip notice, for a clean run with no notice, or for dotted layer names.
Concerns already raised in earlier threads: none, since there were no prior reviews. I posted 7 inline comments.

Record failed batch inputs in history when input loading fails.
When read_path fails, run_tool_with returns at map_inputs(...)? before apply runs, so no history record is created for that item. The batch still counts the item as failed. Record the failure before returning, as apply does for run errors.
Remedy direction
Replace the ? at the map_inputs call in run_tool_with with an Err arm that calls apply(...) with the error. This adds the history record and returns the same error text. I did not write a diff because the borrow of s held by the map_inputs result was not verified against the compiler.

Update run_tool_with so a map_inputs failure records the item’s failure through
apply before returning the same error, matching the history behavior for run
errors. Ensure the change handles the borrow of s safely without changing the
batch failure result.
Give the two folder-test inputs distinct geometry, and check each output against its own source.
batch_run_folder_scanning writes the same Point to both files. The assertions check only the counts and the output layer names. A batch run that feeds the first file's data to every input would still pass. The other batch tests do not check geometry either.
Give each file distinct coordinates. Then check that each output layer holds the geometry of its own source file.

Review comments at @crates/engine/src/cmd/gp.rs:
- Around line 1076-1079: Validate batch_param against the selected tool’s
declared parameters before entering the batch loop; reject an unknown name with
an error instead of silently inserting it into each item’s parameters. Use the
tool specification and parameter symbols already available in this flow, and
preserve the existing behavior for valid parameters.
- Line 15: Update the gp.batch help text’s param default description to explain
that it auto-detects the tool’s first layer-kind parameter, falling back to
"input" when none exists; match the wording in docs/user-guide/analysis.md.
- Line 15: Update the gp.batch parameter description to declare the top-level
batch_param and output_pattern keys that the handler reads as fallbacks.
Preserve the existing param and outputPattern descriptions and include the
fallback keys so validation and parameter-documentation checks recognize them.
- Around line 771-774: Update the scalar Layer file-loading branch to check for
a same-named standalone table before reading the working-directory file. Reuse
the existing table lookup for snap.tables so the file is skipped when a table
named name exists, while preserving the other loading conditions.
- Around line 771-774: Prevent Output::File writes from overwriting files used
as inputs: track the file-input names discovered by inputs_of and check each
destination with names_file before writing, returning an error on a match. Pass
this input information from run_tool_with into apply or write_file_output, and
ensure the check also covers the output path used by gp.run.
- Around line 1030-1032: Update the folder enumeration logic in the batch
target-building flow to propagate errors from both `std::fs::read_dir` and
individual directory iterator entries instead of silently skipping them.
Preserve the existing file filtering, sorting, and target collection behavior
when the folder is read successfully.
- Around line 761-772: Update reaches to classify scalar layer parameter kinds
as file access when gp.run can fall back to reading a path, so the files
permission check applies to those reads. Preserve existing permission handling
for Path and VectorLayers and avoid requiring files permission when the input
resolves to a session layer.
- Around line 14-16: Update the `touches_files` check to include `gp.batch`
alongside `gp.run` when resolving the tool through `tool_id`. Preserve the
existing file-writing classification so batch runs using layer names are
recognized as file access.
- Around line 1073-1074: Update the batch output-name construction around
`base_name` and `out_name` so `{input}` uses the full name when the target is a
layer, preserving names such as `Cities.v2`; retain the existing stem behavior
for file targets. Use the batch command’s existing target classification to
distinguish layers from files.
- Line 1082: Update the gp.batch execution path around run_tool_with to handle
GeoLibre tools in web builds through the browser-supported asynchronous
execution path used by external_start, rather than invoking the wasm32 runner
that returns an error. Establish how to await and collect each tool’s result
while preserving native execution and existing batch history behavior.
- Around line 979-993: Update the parameter-kind selection for batch_param to
include ParamKind::VectorLayers so merge binds each batch item to its inputs
parameter. Before relying on this selection, verify that layer_list accepts a
single name string; if not, use the existing supported representation that binds
each item correctly without reusing the full inputs list.
- Around line 1084-1085: Update the batch output-name reporting around
`succeeded.push` and `output_names.push` to report each added layer’s applied
name, not the requested `out_name`. Use the added layer’s ID to retrieve its
final name, including any suffix assigned for collisions, and return those names
in `outputs`.
- Line 1079: In the batch export flow that builds out_name before inserting it
into the output map, track names already produced and check each name before
running its item. For duplicates, use the existing per-item failure and progress
handling to skip the export; otherwise record the name and continue.
- Around line 985-989: Update the gp.batch input-loading flow for
ParamKind::RasterLayer so raster file paths are loaded and made available to
MapInputs::raster before each batch item runs. Preserve lookup of already-loaded
map layers and ensure valid raster paths no longer fail as missing layer names.
Review comments at @docs/user-guide/analysis.md:
- Line 161: Remove the unsupported fixGeometries reference from the tool table,
Check and Fix section, and gp.run example unless a tool with that ID is actually
registered; if it is registered, ensure the registration makes the documented
lookup succeed.
- Around line 81-90: Update the work-limit paragraph for Viewshed, IDW
Interpolation, Kriging, and Kernel Density to state that caps apply only to runs
that cannot be stopped while running; explicitly preserve the exemption for
rustgis-cli run invoked with stdin and stderr attached to a terminal. Keep the
existing limits and desktop/web behavior clear.
- Around line 860-864: Update the Check Geometry output description to document
the `output` layer (default `<input>_check`) rather than a standalone validation
table. State that it contains only features with problems, retains their
attributes, adds the text fields `problem` and `detail`, and writes features
with non-finite coordinates without geometry; preserve the existing line-check
behavior description.

Included review availability: This review used your included allowance. Your plan provides up to 8 included reviews per hour; 7 remain after this review.
Four inline comments are posted. Three are new, and one re-raises an earlier concern whose code has moved.
Bugs
The batch's own progress never works: each item resets the shared Control to 0 via run_under (crates/analysis/src/lib.rs:488), so the PR's "macro progress" claim does not hold. Confidence high. Inline.
Re-raised: a misspelled param is silently ignored, so every item can run on the same layer and report success. Confidence medium-high. Inline.
merge (its input is VectorLayers) is not bound by the batch binder, so every item fails. Already raised, unchanged; left alone.
Batch runs of file-writing tools (SaveFile) are not refused. Each item queues a file export, queue_file caps pending downloads at 8, so later items fail, and outputs lists names that are not layers. Confidence medium; I did not trace the browser and desktop delivery paths.
Security
gp.batch reads any non-layer inputs entry that is a file, but the plugin reaches check and the task touches_files check classify it by tool kind and path shape, so a bare file name passes without the files permission. Confidence medium-high. Inline. This is new code, though the same gap exists for gp.run.
Performance
No findings.
Quality
Nits, not posted inline, for the release quality pass: the "folder ignored" notice tests is_some() but the logic tests for non-empty targets; the summary says "complete" after a cancel; a failed item still reserves its output name, so a later name gets a suffix with a "collided" notice that is misleading.
Missing tests for the notices the code emits: the "inputs and folder" notice, the output-collision notice, and the skipped-input notice.
AGENTS.md
Never silent: non-string or blank inputs entries and a non-object params are dropped without a notice. Confidence high. Inline.
Test-both-ways: the notices above lack their lossy-input tests.
Already raised, left alone: 22 prior threads. 16 are resolved or no longer apply because the diff changed (the doc-deletion threads refer to content this PR no longer touches). Six are still open and unchanged (the merge binding, raster file paths, the GeoLibre web path, and three gp.run file-access items), so I did not re-post them. One re-raised with new detail (the param validation).

Review comments at @crates/engine/src/cmd/gp.rs:
- Line 1094: Update the output-name handling around the `final_out_name`
collision check so it accounts for the temporary file input added to the map
before reserving the result name. Ensure `outputs` reports the actual
result-layer name after any deduplication, rather than the name of a temporary
layer that is removed.
- Around line 1164-1165: Update the `temp_layer_id` cleanup in `gp.batch` so
successful `Output::Update` results from `calculateGeometry` are retained or
exported before the temporary input layer is removed. Preserve cleanup for cases
where no successful update needs to be saved, and use the existing
update-persistence path rather than introducing a new API.
Review comments at @crates/engine/src/cmd/items.rs:
- Around line 780-781: Update touches_files so imported-task checks account for
bare relative file names used by gp.batch, which can otherwise pass the guard
and be read from the working directory. Because touches_files cannot distinguish
project-layer names from file names, establish the policy for preserving layer
batching versus blocking these inputs before changing the guard; continue
rejecting absolute and ../ paths.

Batch cancellation never reaches the running item.batch() builds its own Control, and nothing outside the tests can cancel it. Each item also runs under a separate item_control, so a cancel that does arrive is not seen by the in-flight item. The PR body's "aborts the active item in-flight" is not true. Confidence: high. Inline comment posted at gp.rs:1183.
Standalone tables lose their dotted name. A table Roads.2020 falls through to file_stem, so its output is Roads_buffer. Confidence: medium. Inline comment posted at gp.rs:1123, with a suggestion.
Folder notice can be false. "running 'inputs' and ignoring 'folder'" fires even when inputs yields no targets, and then the folder is scanned. Confidence: high. Inline comment posted at gp.rs:1008.
Security
No new issue found. The read gate now covers every non-wildcard inputs entry (plugins.rsreaches, items.rstouches_files), which closes the bare-name bypass raised earlier.
Performance
Nothing significant. Folder and input lists are unbounded, and each file is loaded whole, one at a time. Confidence: low.
Quality
Never silent: the file reader's report is discarded (Ok((dataset, _report))), though inputs_of forwards the same messages. Confidence: high. Inline comment posted at gp.rs:1144.
One notice per kind: output-name collisions notify once per item. Confidence: high. Inline comment posted at gp.rs:1134.
Nits, grouped:
The wildcard check is repeated in gp.rs, items.rs and plugins.rs; one helper would do.
gp.rs shadows s (the Session) with |s| in the wildcard closure.
The docs omit that inputs also takes a single string.
run_batch_with is pub but only tests use it.
AGENTS.md
Screenshots link to a fork's raw.githubusercontent.com branch, not opengeos/rustgis-assets.
The PR body's "Macro progress" and "in-flight cancel" claims are not accurate for the code as written.
Already raised, left alone (no new post): the file-input output-name collision and the lost Output::Update on temporary layers, both still present, plus the GeoLibre-on-web and bare-name policy threads. The earlier progress-reset concern no longer applies, because the item now runs on its own control. Its replacement is the cancellation finding above. The earlier security-gate and missing-param threads are fixed in this head.

Record a replayable file input.
For native file targets, history stores the temporary layer name in the individual gp.run record. The batch removes that layer after the item completes. History replay and task.new with fromHistory then cannot resolve the recorded input. This affects single-string inputs, input arrays, and native folder inputs.
Preserve the original file path in the recorded command, or add a supported batch-level replay record that retains the file paths.

If the supplied control is cancelled before the first item, the loop stops, but this reports “all 0 succeeded” and returns no cancellation status. Report cancellation separately so callers can distinguish an incomplete batch from a completed one.

- Around line 1177-1180: Update the item control creation in the batch execution
flow so `item_control` observes cancellations made to `control` after it is
created, while keeping item progress separate from batch progress. Preserve the
existing stoppable behavior and ensure `run_tool_with` can detect cancellation
throughout the active item’s execution.

- Around line 785-786: Update the `gp.batch` file-access validation around the
`params.get("inputs")` wildcard check to include tools classified by
`reads_files` as well as `writes_files`; apply both classifications to wildcard
batches so file-reading tools cannot bypass the check.

Thank you for the static review! We have addressed both issues and updated the roadmap:
Reader Warnings & Diagnostics Retention:
Rather than capping at three messages, reader warnings across all files are aggregated by warning kind with counts and affected inputs in session notices (e.g. gp.batch: 2 input(s) had dropped Z or M values (f1.geojson, f2.geojson)).
In addition, the full diagnostics are preserved in each file input's replayable history record (GpRecord::messages) and returned in the batch result under "warnings": [{"input": ..., "warning": ...}].
All-Failed Batch Error Handling:
In accordance with "Unusable results are errors", gp.batch now returns an Err when no items succeed (num_ok == 0), including individual failure reasons in the error message (e.g. Batch 'buffer' failed: all 2 inputs failed: ...).
Succeeded, failed, and attempted counts alongside the "errors" array are properly preserved.
Roadmap & Upstream Sync:
ROADMAP.md has been updated with Batch runs: one tool over many layers or a folder of files ([#1458](https://github.com/opengeos/RustGIS/pull/1458)) under Underway, and GEOLIBRE_PARITY.md has been updated accordingly.
Merged the latest origin/main into the branch (cleanly integrating the upstream execution cache).
All review threads from GitHub Actions and CodeRabbit have been addressed and resolved. Re-triggered CodeRabbit review for the current head commit (b0665eda).
All tests, clippy, and layering checks are passing cleanly. Ready for merge!
Reviewed the full PR diff (gp.rs gp.batch runner, items.rs/plugins.rs file-access gating, analysis alias helper, history replay, docs) against pr-context/AGENTS.md. I did not compile or run tests; the wasm finding rests on reading the cfg blocks.
Bugs
Browser build skips the wildcard error and rejects an empty folder (crates/engine/src/cmd/gp.rs:1352, posted inline). The wasm folder check lacks the !is_wildcard gate and trimming that the native path has. inputs: "*" with a folder on an empty map gives the wrong message, and "folder": "" gets the browser error. Also "folder": "" with inputs raises a spurious "both 'inputs' and 'folder'" notice (line 1243). Confidence: high. Severity: low.
Security
Nothing new. I checked the touches_files, reaches and layer_name_left_out gating for gp.batch. Folder scans skip symlinks, and wildcard runs only classify as file access when the tool or a static parameter names a file. Layer-name inputs also require file-access approval, which the docs state; that is a usability trade-off, not a hole. Confidence: medium.
Performance
No cap on the number of items in inputs or a folder scan. Each item runs a full tool and history record, so a very large folder runs unbounded. AGENTS.md asks for clamped sizes. Confidence: low, since this is a design gap rather than a demonstrated failure.
Quality
run_batch_with is about 830 lines. The folder scan and the per-item logic would read better as separate functions. Confidence: high. This is a quality point for the release pass.
The all-fail thread reply says run_batch_with "preserved the Ok(ret) result with succeeded: 0". The code now returns Err (around line 907), matching the docs. The reply is stale and should be corrected. I did not re-raise the concern. Confidence: high.
The non-UTF-8 test ignores the result of std::fs::write (gp.rs:3602). A failed write would show up as a confusing assertion failure. Confidence: medium. Minor.
AGENTS.md
No unwrap, expect, panic, unsafe or indexing in new non-test code that I could see. Notice-with-count patterns follow the Never-silent rule. The new command is registered, so hostile_params_never_panic covers it. ROADMAP and GEOLIBRE_PARITY are updated. No new dependencies. Labels follow the existing gp.run style.
Earlier review threads: 131 threads on this PR, all resolved. I read the first ~680 lines of prior-reviews.json in full and searched the rest by keyword and state. I left alone every concern that was already raised, including the JOIN_FIELD_ALIASES drift and the in-place calculateGeometry case, which was fixed in 0df3ea3. I re-raised none.

Included review availability: This review used your included allowance. Your plan provides up to 8 included reviews per hour; 5 remain after this review.
Low severity, medium confidence: a batch item whose inputs fail to map (an existing layer of the wrong kind, for example) returns before apply_inner, so it has no gp_history entry. The PR says every run is logged. Posted inline on crates/engine/src/cmd/gp.rs:2028 with a suggestion.
Security
No new issues. I checked the file-access gating for gp.batch: touches_files, reaches (including the early return, which skips nothing it needs because gp.batch is not in REACHES_FILES or READS_FILES), the wildcard and folder paths, and the history replay. The gate holds for the cases I traced.
Performance
Low: distinct_tool_messages and reader_warnings are scanned linearly for each item, so a large batch with per-item messages is quadratic. Not worth blocking on.
Low: apply_inner clones result.messages for every item, including gp.run. This is already noted in an earlier thread.
Quality
Doc comment on run_batch_with (gp.rs:1089) says "with cancellation and progress reporting". Progress reporting was removed, so the comment is stale.
run_tool_internal takes two positional bools. Already raised, left for the release quality pass.
AGENTS.md
No violations found in the new non-test code: no unwrap, expect, panic, indexing or unsafe; notices are aggregated with counts; file-input loss is reported; wasm gating is in place.
tl! is not used anywhere in crates/engine, so the translatable-text rule does not apply to these notices.
Already raised, left alone
Four open threads still apply to the current code and I did not repeat them: the ungated wasm folder check (gp.rs:1351), joinField alias precedence over the batch input (analysis/src/lib.rs:391), the tool-message sample cap (gp.rs:1787), and imported gp.run reading bare file names in inputs (items.rs:854).
About 90 resolved threads are visible in the staged file. The file itself says 38 more were left out, and I could not read them.
Reviewed without running: I did not compile, run the tests, or run cargo fmt/clippy. Every finding comes from reading the diff and the surrounding source.
Change size
Compared with the base branch: the whole PR against main (merge base 009b80f to PR head 71be0d1). Not the latest push.
Re-raised (inline): a batch item whose layer input fails map_inputs (e.g. a raster passed to a vector tool) leaves no gp_history entry. The guard now tests opts.command, which is only set for file inputs. Fix: test opts.record. Confidence: medium-high.
Latent, low confidence: the reader-warnings fallback (errors.last(), around line 1828) could attach another item's error to a successful item's history record. I did not find a path that reaches it, so I did not post it.
Security
No new security findings. File access is declared through gp.batch's Files and Automation effects, and the assistant asks each time.
Performance
Inline: no upper bound on items from inputs, "*" or folder. Confidence: medium.
Low: distinct_tool_messages is scanned linearly for each message, so runs with many distinct per-item messages get quadratic. Negligible at typical sizes. Confidence: low.
Quality (may wait for the release quality pass)
run_batch_with is about 720 lines. The history push-and-trim block is repeated three times, and record_json is built in three places. Extracting helpers would help.
batch_run_folder_skips_symlinks passes without asserting anything when symlink creation fails (if linked). Windows never checks the skip behaviour.
On a batch where every input fails, the error-severity summary notice and the returned Err both report the failure. Harmless, but redundant.
AGENTS.md
Screenshots in the PR body are hosted on the author's fork (raw.githubusercontent.com/quanguet0409/RustGIS/assets/...). AGENTS.md says images live in opengeos/rustgis-assets. Confidence: low-medium; I did not check the attachment guidance in docs/contributing.md.
Otherwise the change follows AGENTS.md: no unwrap/expect in non-test code, notices for dropped inputs, options and reader losses, cfg gating for wasm, and tests in the test module.
Already raised, left alone: I read 132 earlier threads, 5 still unresolved. I did not re-post the unresolved ones whose code is unchanged: the wasm folder gate, the joinField alias precedence, the tool-message cap at three, and the imported-task file read in items.rs. I also did not re-post the cancellation-reachability and replay concerns, which the author answered.
Change size
Compared: the whole PR compared with the base branch (merge base 43250bf to PR head 4ef7f01).
- gp.batch: the browser's folder refusal follows the native gates, so
a wildcard keeps its own error and a blank folder is ignored; a
blank folder beside inputs no longer says both were given.
- gp.batch: a static Join Field alias (`input` for `target`) no longer
stands in for each batch input; the analysis crate names a tool
parameter's aliases (param_aliases).
- gp.batch: every distinct tool message is named in the batch notice
(up to 50) and all of them are in the result's `messages`, so a loss
reported after the third kind is not hidden.
- gp.batch: an item whose input can't be mapped is kept in the history
as a failed run, layer inputs included.
None new that I could confirm by reading. Cancellation, collision naming and table handling are already covered by open threads. Every unwrap/expect in the diff sits in test modules.
Security
None new. Batch file reads are gated by the command-level Files effect and per-item authorize_tool. Imported tasks and the assistant route gp.batch through the approval path.
Performance
Already raised, not repeated: no cap on batch size (folder scan plus per-item layer_by_name scans are O(N·layers)).
Quality
Declaring Effect::Files on every gp.batch call, including "*", contradicts the PR body. The body says an in-memory wildcard is not file access. The test batch_reaches_files_and_is_reserved_to_the_user pins the stricter behaviour, so the body or the code should change. Confidence: high that they disagree; the code is the more conservative choice. Left as a body fix, not posted inline.
Never silent (AGENTS.md)
Batch input silently removes alias values from params (gp.rs ~1608 and ~1619). Only params.<batch_param> gets a notice. Posted inline with a suggested notice. Confidence: medium-high.
Already raised, left alone
41+ earlier threads are still open or were answered. I did not re-raise them, including: the batch size cap, cancellation not reachable from the app, the JOIN_FIELD_ALIASES drift risk, and the gp.runtouches_files scope. Several replies in those threads describe changes (e.g. narrowed Reach::Files, item_control) that are not in this head. I did not verify those replies beyond what the diff shows.
AGENTS.md
No unwrap/expect/panic in non-test code, no unsafe, no new dependencies, and no wasm-only mutability issues I could find. Docs for gp.batch match the code, apart from the alias notice gap above.
I posted one inline comment. I did not approve or modify anything.
Change size
Compared: the whole PR against main (merge base 43250bf to PR head be5486f).
Thanks @quanguet0409, batch runs were a long-standing roadmap item and this covers them well. What I changed on your branch before it merged:
Merged main, which had just landed the new command-permission policy (fix(security): bind approvals to exact execution scopes #1461). The old touches_files/reaches checks this PR extended are gone, so gp.batch now declares its effects: Files and Automation, plus its tool's plugin or unreviewed-runner effects. Every batch is file access, the AI Assistant asks each time, and plugins and imported items can't run one. Each item's tool run goes through the same authorize_tool admission as gp.run. Batch items pass their history record, quiet notices and table naming through RunOpts.
Review fixes: the browser's folder refusal matches the native gates, a static Join Field alias no longer stands in for each batch input, every distinct tool message is named in the batch notice, and an item whose input can't be mapped is kept in the history.
Rewrote the docs section for the new permission model and removed the Underway roadmap entry.
Two fixes from the last review round (a 10,000-input cap and a notice for dropped aliases) arrived after the merge and are in #1582.
…1582)
* fix(engine): cap gp.batch's inputs and report dropped input aliases
Follow-up to #1458, from its last review round:
- gp.batch refuses more than 10,000 inputs, with the count, before
running any, so a hostile list or folder can't make it unbounded.
- gp.batch reports the other names for its input parameter given in
`params` (Join Field's `input` for `target`) that each item drops.
* fix(engine): count gp.batch notices from the monotonic mark
The static-alias notice test took its mark from the kept-notice queue
length. That queue is trimmed to 200 entries, so the mark stops
matching once it is full. Take the mark from notice_mark() instead,
which counts every notice given.
Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
Applied by the claude-autofix workflow.
* Address review feedback
- The dropped-alias notice names every alias, not only the first.
- A folder batch is refused while it is read once the folder holds
more than ten entries per allowed input, and refused with the count
before sorting when it has more supported files than a batch runs.
- Tests: a batch at exactly the limit is accepted; a folder over it
is refused before any item runs.
* chore: drop empty placeholder files the autofix run committed
* Address review feedback
- gp.batch folder scan holds only files it can run or that may be
sidecars, and counts subfolders and other files without holding
them, so a folder of many unrelated files runs its data files again
instead of being refused. The cap now limits what is held, and its
message says the folder has too many data and sidecar files to read.
- Test both ways: a folder with one CSV and more other files than the
cap runs it and reports them skipped; a folder over the cap in
sidecar candidates is refused with no item run or recorded. The cap
is smaller under test so the tests write about 10,000 files.
* Address Claude review feedback
- gp.batch folder scan holds an .xml file only when it is named
<name>.shp.xml, the one form that can be a Shapefile sidecar, so a
folder of many unrelated .xml files runs its data files instead of
hitting the entry cap. The many-other-files test now uses .xml files
to cover this.
- The folder limit tests remove their temporary folder before they
check the result, so a failing assertion doesn't leave the files
behind.
* Address Claude review feedback
- gp.batch reads a folder in two passes instead of holding every
possible sidecar: the first pass holds only the files a batch runs
and the Shapefile and GeoPackage names, the second counts sidecar-like
files that match neither as skipped. Orphan .dbf, .prj and similar
files no longer count toward any limit, so the folder entry cap is
gone and only the 10,000-file batch limit stays, now checked while the
folder is read.
- Test a folder with one CSV and text, unrelated .xml and orphan .dbf
files: the CSV runs and all of them are reported skipped. The
over-limit folder test also checks that no item was attempted.
