fix(engine): annotations and report exports cover all of a layer read in place by Mavrick-F · Pull Request #1728 · opengeos/RustGIS

Mavrick-F · 2026-11-10T13:26:17Z

Summary

A layer read in place (a large file, any PostGIS, MySQL or SQL Server table, a file by its web address) holds only the features of the current view. Convert To Annotation and Export Report used those held features as if they were the whole layer:

labels.convert made annotations for the features in view only, then turned the layer's own labels off. The other features were left with no labels at all.
report.export listed only the records in view. Its subreports and related reports did the same with their layers, and a "selected only" report matched the selection by window row.

Nothing said any of this. Both now use every feature of the source, read as Load All Features reads it, and the live layer stays read in place:

Convert To Annotation
- In the app, a click on Convert for a layer read in place reads the source on a thread of its own first, with progress and Cancel. This is the same read-ahead Load All uses (reads/readjob, now shared in cmd/whole.rs; Load All uses it too).
- A script, the assistant or the command line reads where the command runs.
Export Report
- It now runs as a background export, like Export Layout, with progress and Cancel a page at a time.
- It draws from a copy of the project in which the report's own layer, its subreports' related layers and its related reports' layers are read whole. Selections are kept by feature id, including one saved with the project before its view is read.
- A layout drawn inside a report still draws its map frames' views. A source that fails there is said, as Export Layout says it.
Report preview
- It still draws the records in view (it redraws as you edit). Its record line now says so when the report's layer, or a subreport's, is read in place: "in this preview, only the records in the map's view; the export lists them all".
Unreadable rows
- Rows a source can't read are left out and said once, worded as Load All words it.
Permission effects
- These commands' permission effects include the sources they read whole, as layer.loadAll's do. An assistant's call that would read a web or database source asks first.

In the browser, a layer read in place from a web address can't be read whole. Load All and Export Features already refuse it with "download it to load it whole", and these exports now say the same, instead of giving a result limited to the view.

Follows #1716, which added the shared cmd/whole.rs.

Testing

labels_and_reports_of_a_layer_read_in_place_use_its_whole_source: a streamed GeoJSON whose view holds one of its three points.
- Convert gives three annotations, both read here and read ahead; the layer stays read in place.
- The report preview says it shows the view. The export's copy lists all three, and a selected-only report keeps the one selected point although its window row differs from its source row.
- A file with an unreadable row says it once per command; a clean one says nothing.
labels_of_a_layer_read_in_place_convert_after_a_read_on_a_thread (app): Convert from the user's click starts the read on a thread, and the annotation lands with every feature.
permission_policy_labels_and_reports_read_whole_reach_their_source: both commands reach a web source for a layer read in place, and not for the same layer in memory.
long_commands_stop_when_cancelled_while_they_run now runs Export Report. reads_made_ahead_are_taken_by_the_command still passes on the shared read-ahead.
cargo xtask ci, the wasm build of rustgis-web, and the pre-commit hooks.

Summary by CodeRabbit

New Features
- Converting a streamed layer to annotations now considers all source features while leaving the layer streamed.
- Report exports include all records from streamed report layers and related layers, without changing the live session.
- Desktop report exports and streamed-layer annotation conversions can run in the background.
Improvements
- Report previews clarify when they show only records currently in the map view, while exports include all records.
- Notices identify when source rows could not be read, including during streamed-layer conversion and loading.

… in place Convert To Annotation and Export Report took the features a layer read in place holds for the view as the whole layer. Both now read its source whole, as Load All Features does, and say rows it can't read: Convert To Annotation reads ahead on a thread of its own in the app (the read-ahead Load All now shares), and Export Report runs as a background export drawn from a copy of the project whose report layers are read whole, selections kept by feature id. The report preview says when it shows only the view's records. Permission effects reach the sources these read.

Walkthrough

Streamed-layer annotation conversion and report exports now read source features beyond the current map view. Desktop conversion and report exports use background jobs. Report previews remain limited to records in the map view.

Changes: Whole-source workflows

Layer / File(s)	Summary
Shared whole-layer read support `crates/engine/src/cmd/whole.rs`, `crates/engine/src/cmd/layer.rs`, `crates/map/src/lib.rs`	Shared helpers prepare or perform whole-layer reads, validate read-ahead results against the layer source and fields, and preserve selection by feature ID. `layer.loadAll` now uses these helpers.
Streamed-layer annotation conversion `crates/engine/src/cmd/labels.rs`, `crates/engine/src/cmd/reads.rs`, `crates/engine/src/policy/dispatch.rs`, `crates/ui-egui/src/lib.rs`, `crates/ui-egui/src/panes.rs`, `crates/ui-egui/src/readjob.rs`	Conversion uses all source features for streamed layers and reports unread rows. Desktop conversion prepares the read through a background read job.
Whole-source report export `crates/engine/src/cmd/report.rs`, `crates/engine/src/cmd/exports.rs`, `crates/engine/src/cmd/layout.rs`, `crates/ui-egui/src/lib.rs`	Report exports load reported streamed layers in a detached project copy and use shared export handling. Desktop report exports start through the background export job. Report previews indicate when they show only records in the map view.
Workflow validation `crates/engine/src/tests.rs`, `crates/engine/src/tests/permission_policy.rs`, `crates/ui-egui/src/readjob.rs`	Tests cover whole-source conversion and reports, read-ahead, unread-row notices, selection, export cancellation, network approval, and desktop background conversion.

Bug (medium, ~80% confidence): reported_layers ignores the depth bound that blocks applies, so an export can fail on a layer the report never draws.

blocks recurses into a related report only while depth < MAX_DEPTH (MAX_DEPTH = 3, report.rs:25, checked at the Section::Related arm around line 933). This function has no depth limit, so it reads layers of related reports that are never drawn. whole_copy propagates a failed read with ?, so one unreachable source aborts the whole export. The doc comment's "a report appended too deep to be drawn only costs a read" holds only when the read succeeds.

Failure scenario: a top report that nests four related reports deep. The fifth report's layer is a streamed PostGIS table that is down. The preview and the drawn PDF both omit that report, yet Export Report fails with that layer's error.

Suggested fix, tracking depth the way blocks does:

Suggested change

let (mut out, mut seen, mut todo) = (Vec::new(), vec![i], vec![i]);

while let Some(i) = todo.pop() {

let Some(r) = s.project.reports.get(i) else { continue };

let Some((m, id, name)) = place(&r.layer) else { continue };

out.push((m, id));

for sec in &r.sections {

match sec {

Section::Subreport { relationship, .. } => {

let other = relationships(input)

.find(|x| x.name.eq_ignore_ascii_case(relationship))

.and_then(|rel| opposite(rel, &name).map(str::to_string));

out.extend(other.and_then(|other| place(&other)).map(|(m, id, _)| (m, id)));

}

Section::Related { report } => {

if let Some(j) = s.project.reports.iter().position(|x| x.name.eq_ignore_ascii_case(report))

&& !seen.contains(&j)

{

seen.push(j);

todo.push(j);

}

}

let (mut out, mut seen, mut todo) = (Vec::new(), vec![i], vec![(i, 0usize)]);

while let Some((i, depth)) = todo.pop() {

let Some(r) = s.project.reports.get(i) else { continue };

let Some((m, id, name)) = place(&r.layer) else { continue };

out.push((m, id));

for sec in &r.sections {

match sec {

Section::Subreport { relationship, .. } => {

let other = relationships(input)

.find(|x| x.name.eq_ignore_ascii_case(relationship))

.and_then(|rel| opposite(rel, &name).map(str::to_string));

out.extend(other.and_then(|other| place(&other)).map(|(m, id, _)| (m, id)));

}

Section::Related { report } => {

// As `blocks` draws them: none appended past MAX_DEPTH.

if depth < MAX_DEPTH

&& let Some(j) = s.project.reports.iter().position(|x| x.name.eq_ignore_ascii_case(report))

&& !seen.contains(&j)

{

seen.push(j);

todo.push((j, depth + 1));

}

}

_ => {}

}

}

}

Fixed in 689036c: reported_layers now walks the reports a report appends exactly as blocks draws them (same order, the same shared seen, and depth < MAX_DEPTH), so an export reads no layer past the depth drawn and can't fail on one. New test a_report_export_reads_only_the_layers_it_draws: a chain of five reports exports with the first four layers only.

AGENTS.md, Never hold the window (~50% confidence). The guideline asks that a command which must run on the UI thread say why in its doc comment. This comment says where the read runs for each caller but not why the whole read may hold the window for scripts and the command line. App::run routes only archive reads to a thread (crates/ui-egui/src/lib.rs, RustGisApp::run), so a labels.convert that arrives through it reads the full source on the UI thread. The Convert button and the layer menu are covered by run_by_user.

Either route labels.convert in App::run as well, or add the reason here.

Fixed in 689036c: the doc comment now says why the conversion itself runs on the app's thread. It adds the annotation layer and turns the layer's labels off in one undoable step, a pass over features already in memory. The whole read before it runs on a thread of its own.

Code review

Bugs

reported_layers (report.rs:1046–1066) has no depth bound, but blocks stops recursing at MAX_DEPTH = 3. An export can therefore fail on a layer the report never draws, because whole_copy propagates the read error. Inline comment with a suggested fix posted. Confidence ~80%.

Security

None found. The permission effects now include sources read whole, and a test covers both the in-memory and web-source cases.

Performance

Scripts and the command line run labels.convert on the UI thread, since App::run only routes archive reads to a background thread. The Convert button and layer menu are covered by run_by_user. Confidence ~50%; covered in the AGENTS note below.
labels::convert clones the whole live layer, including its view dataset and source caches, before replacing the dataset. Low impact, ~40% confidence.

Quality

take_or_read (whole.rs:116) returns read errors without the layer name, while load_into and Whole::read add it. Low.
Doc comments wrap awkwardly in readjob.rs:66–70 and reads.rs:2–4. Nit.
The background report export on a thread (exportjob → export_start) has no test with a streamed layer. The engine test goes through s.run, which lands synchronously. Low.

AGENTS.md

labels.rs:651–652: the doc comment says where the read runs but not why it may hold the window. Inline comment posted. Confidence ~50%.

Earlier review concerns already raised: none, since the PR had no prior threads.

Compile and test status was not verified here; I had no build tools, so these findings come from reading the diff and the surrounding code.

reported_layers walks the reports a report appends as blocks draws them (same order, same depth), so an export no longer reads, or fails on, a layer past the depth drawn. labels.convert's doc says why its conversion runs on the app's thread. The tests use a unique folder, and the permission test covers a web source reached only through a subreport or an appended report.

Bug (performance): a streamed layer's whole source is read before the command checks it has any labels to convert.

The whole read runs here (and, in the app, on the read-ahead thread from reads.rs:102). The check at line 681 (the layer has no label field) comes after it. A layer with no label settings therefore reads its entire source, possibly a large PostGIS table, and then fails with that error. The read result is discarded.

Failure scenario: a PostGIS layer read in place with no label field set. Clicking Convert starts a full background read, then reports "the layer has no label field".

Suggested fix: move the label-field check onto the live layer before take_or_read, using the same fields/by_text logic. Factor it into a helper, such as has_label_field(l: &Layer), and call it in reads::prepare for labels.convert before whole::ahead, so no read is queued either. Add a test that a streamed layer with no labels fails without reading its source.

Confidence: high (about 85%).

Fixed in 6534525: convert checks first that the layer has label text (a class's label field or a text expression, decided on its fields by has_label_text) and refuses before any whole read. The app's read-ahead (reads::prepare) checks the same and makes no read when there's nothing to convert.

AGENTS.md, Never hold the window (about 55% confidence). This re-raises the earlier thread on labels.rs, because the code it points at has changed and the problem remains.

The routing here covers only the user's clicks (run_by_user: ribbon, layer menu, shortcuts, command search). App::run (around line 2258) sends only archive reads and topology to readjob when reads_off_frame is set. So a labels.convert from the assistant, a script or the CLI on the desktop runs Session::run on the UI thread. For a layer read in place, that thread does the whole source read.

The labels.rs doc comment now says where the read runs for scripts and the assistant. It does not say why that path has to hold the window, which the rule asks for. Either route labels.convert through readjob for streamed layers in App::run too, or give that reason in the doc comment.

Fixed in 6534525: labels.convert on a layer read in place now goes to readjob from RustGisApp::run when reads_off_frame is set, next to the archive and topology reads, so every caller in the app (a click, the assistant) reads on a thread of its own. run_by_user no longer has its own branch. Scripts (run inside the engine) and the command line read where the command runs, which the doc comment now says.

Code review

Bugs

Convert To Annotation reads a streamed layer's whole source before it checks the layer has any label field. A layer with no labels therefore does a full source read, then fails with "the layer has no label field". reads.rs:102 queues the same read in the app before the command runs. Posted inline at labels.rs:660. Confidence: about 85%.

Security

No issues found. labels.convert and report.export now include the sources they read whole in their permission effects, and the new test covers this.

Performance

The whole-source read happens before validation (see Bugs).
The report export clones the project on the UI thread via detached. layout.rs already does the same, and features are shared through Arc, so this is consistent and not a new cost.

Quality

Several overlapping whole-read helpers now exist: Whole::of/read, whole::ahead, take_or_read and load_into. convert does not use Whole, and it clones the whole layer to build its copy. Better left for the release quality pass.
The ReadAhead alias in whole.rs shares a name with reads::ReadAhead.

AGENTS.md

Never hold the window, for scripts, the assistant and the command line: a streamed labels.convert still reads on the UI thread, because App::run routes only archive and topology reads to readjob. The labels.rs doc comment now says where it runs but not why. This re-raises the earlier thread on labels.rs, because the code changed and the problem remains. Posted inline at lib.rs:2213. Confidence: about 55%.
report.export as a command (command search, assistant, script, CLI) still calls write_here on the UI thread, as layout.export does. Only the ribbon's ui.exportReport uses the background export. The PR text says "runs as a background export, like Export Layout", which is true only for the ribbon path. Confidence: about 50%. Not posted inline.
Never silent, one notice per kind: a report that lists several streamed layers with unreadable rows gets one notice per layer, not one per kind with a count. Confidence: about 35%.

Earlier threads

Depth bound in reported_layers (report.rs): addressed. walk uses depth < MAX_DEPTH as blocks does. Not re-raised.
Permission test covering only the primary layer: addressed by the new subreport and appended-report cases. Not re-raised.
Temp directory name collision in tests: addressed by the nanosecond suffix. Not re-raised.
Two earlier concerns were left alone, and two posted again with new context (the labels.rs UI-thread concern is posted again; the depth bound is not).

I did not compile or run the tests. Everything was checked by reading the diff and the surrounding source.

…er off the frame Convert To Annotation checks the layer has label text before a layer read in place is read whole, here and before the app's read ahead. In the app, every caller (a click, the assistant) gets the read on a thread of its own, through RustGisApp::run as the archive and topology reads do. A report export looks at Cancel between the layers it reads whole.

+            // Converting the labels of a layer read in place reads all of its source first, on a
+            // thread of its own, whoever asks (a click, the assistant).
+            if id == "labels.convert"


AGENTS.md, Never hold the window (about 50% confidence). labels.convert now reroutes through readjob here, but report.export does not. Only the Publish button (ui.exportReport, around line 3526) calls exportjob::start. Command search, the assistant, and scripts on the app go through Session::run, and write_here then runs export_work on the UI thread. That work now includes reading every layer the report lists in full, which can be large for a PostGIS or web source. Layout export has the same gap, so this is a pre-existing pattern, but this PR is the one that adds the whole-source read.

One way to close it, mirroring the convert routing:

Suggested change

if id == "labels.convert"

// Exporting a report reads the layers it lists whole: on a thread of its own, with

// progress and Cancel, whoever asks.

if id == "report.export" {

return exportjob::start(self, "report.export", params);

}

// Converting the labels of a layer read in place reads all of its source first, on a

// thread of its own, whoever asks (a click, the assistant).

if id == "labels.convert"

This follows the app's existing export pattern: Export Layout, Export Map, Export Features and Export Raster also go through exportjob only from their UI entry points (ui.*, e.g. lib.rs ~L3487 and ~L4127). Their commands run where called when an assistant or script names them. report.export is now in the same background-export registry, so it behaves the same. Routing every export from App::run would change all of them, which is outside this fix.

+        let (ds, unread) = super::whole::take_or_read(s, id)?;
+        let mut copy = s.map().layer(id).ok_or("no such layer")?.clone();
+        copy.dataset = ds;
+        copy.source = None;


AGENTS.md, Never hold the window (about 55% confidence). This read is new in this PR, and the conversion loop that follows (line 724, for (row, ft) in l.dataset.features.iter()) now runs over every feature of a layer read in place, not just the view. In the app it runs in land on the UI thread, after the whole read has finished on its own thread. For a large PostGIS or web source that is one long pass with no Cancel check and no progress count, and the window is held for its whole length.

The doc comment's reason ("a pass over features already in memory") explains why the step must run on the app's thread, but not how long it can take. Options: build ds and moved from the copied layer on the read thread, so the UI thread only adds the layer and turns the labels off. Or, if the pass stays here, check Cancel and report progress every N features and say so in the doc comment.

The read, the part that grows with the source and touches files or the network, runs on a thread of its own in the app. The loop that follows is the same pass labels.convert already makes on the app's thread for an in-memory layer of any size, and the doc comment says why it stays there: one undoable step that adds the layer and turns its labels off. Moving the conversion itself off the frame would change it for in-memory layers too, which is outside this fix.

Code review

Bugs

None confirmed. I traced the new paths (Convert and Export Report reads, the report walk, the App::run reroute, and the test expectations) and found no logic error.

Security

None found. Report and label reads of web or database sources now go through the permission effects, and the new tests cover that.

Performance

crates/engine/src/cmd/labels.rs:676 (about 55% confidence): the conversion pass now covers every feature of a layer read in place, and in the app it runs on the UI thread after the read. It has no Cancel check and no progress count. Posted inline with two fixes. This is a Never-hold-the-window concern under AGENTS.md, so it is listed there too.

Quality

crates/engine/src/cmd/labels.rs:695: the old "the layer has no label field" check is now redundant with has_label_text at line 669. Nit.
The error text "only Add Data, Load All, … prepare background work" is duplicated in reads.rs:142 and policy/dispatch.rs:155. A shared constant would keep them in step. Nit.
whole.rs ReadAhead alias has the same name as the reads::ReadAhead struct, which is confusing. Nit.
cmd/report.rs:967 (report_bytes): the notice prefix uses the report name, while export_work uses the file path. Nit.
cmd/report.rs whole_copy: one unread-rows notice per layer, so several streamed layers can produce several notices of the same kind. This is against "one notice per kind with a count". Nit.
labels.rs layers_read_whole asks for internet approval for a Convert on a web layer even when the conversion will refuse for having no label field. Low.

AGENTS.md

crates/ui-egui/src/lib.rs:2268 (about 50% confidence): report.export routes to exportjob only from the Publish button. Command search, the assistant and scripts on the app still run write_here on the UI thread, which now includes the whole-source read. Layout export has the same gap, so this is pre-existing, but this PR adds the read. Posted inline with a suggestion that mirrors the convert reroute.
Quality points above are left for the release quality pass.

Prior review threads

I left 4 earlier concerns alone, because the code they point at changed and the problem is gone: labels.rs:673 (the label check now runs before the read, in both convert and reads::prepare), report.rs:1066 (depth bound now matches blocks), labels.rs:652 (doc comment answered), and ui-egui/lib.rs:2213 (App::run now reroutes streamed labels.convert). The labels.rs:673 thread is still open and can be resolved.
Two inline comments posted. One attempted anchor on line 724 was rejected by GitHub because that line is not in the diff, so the comment is anchored on line 676 instead and refers to the loop at 724.

I could not compile or run the tests here. The findings are from reading the diff and the surrounding source.

Run assistant report exports off the UI thread

An allowed or approved assistant report.export runs through Session::run, bypassing exportjob::start. A whole-source read or report render can freeze the window without export progress or Cancel. Route assistant report exports through a background export path while preserving their approval and completion handling.
