feat(data): publish a layer's edits back to its GeoJSON file (#1385) - #2036
source.publish now writes edits back to a whole-read .geojson source, completing the GeoJSON step of #1385. The existing source.syncState command reports whether the layer, source, or both have changed.
Before replacing anything, publish checks the source fingerprint and original read digest, proves the original document survives a read/write, and validates the edited output through the reader. Foreign members, legacy CRS declarations, duplicate keys, dropped geometry/Z values, nested-property coercion, and number text a rewrite would change are refused. Collection names, document kind, and compatible feature ids are retained; a file with ids refuses row changes that cannot preserve their identities. Removed or renamed properties produce a notice.
The file is staged beside its source with the existing permissions, synced and read back, then the source is checked again before atomic replacement. The shared nonblocking source lock coordinates RustGIS publishers. Read-back rows update the existing sync record after success. No new dependency or project-format field is added.
Testing
All 1,202 data-crate library tests pass, including eight GeoJSON publishing regressions for edits and repeated publication, source changes and symlinks before and during validation, loss refusals, feature ids, renamed fields, empty-schema refusal, single Features and bare geometries.
The engine publishing/log/undo regression passes with its GeoJSON case; assistant discovery reports publication as a project change.
Data/engine/assistant all-target Clippy and the assistant WebAssembly check (including the engine) pass with warnings denied.
Formatting passes; a standards and spec review found one missing Cancel check in the number-preserving traversal, now fixed.
The full Linux CI (tests, Clippy, WebAssembly build, licences, hooks) passes on this head in the fork.
UI evidence
No visible UI change. This extends the existing Publish to Source and Source File State commands to another format.
Edited GeoJSON layers can now be published back to their source files. Publishing is refused if the source has changed or the update could lose data or metadata.
Published layers return to a synced state, and edits remain undoable.
Documentation
Updated the user guide with publishing details for Shapefile and GeoJSON layers, including validation and file replacement behavior.
Roadmap
Removed the planned item for saving edits to Shapefile and GeoJSON layers.
)
source.publish writes an in-memory layer read from a Shapefile back over
that file, after proving nothing but the edits changes: the file is as it
was read and reads as the layer was read, the file read and written again
is byte-for-byte the same table and the same shapes, and the layer written
reads back as the layer. The new parts are staged beside the old, checked,
and swapped in with the .shp last, rolling back on failure.
The rewrite keeps the file's code page and language driver, column widths,
decimals and F types where values fit, its .prj and .cpg, and the exact
coordinates of every unedited shape. It runs as a background export with
progress and Cancel; undo and redo keep each layer's sync record.
Also reads dBase F columns as f64: dbase parsed them into an f32.

…hanges
A text column 255 bytes wide (the most a .dbf allows) with a longer value
crashed in clamp; it now gets the 254 bytes written. A column that couldn't
hold its values is named with its old and new form ('ACRES' N(10,2) to
N(24,9)), as a number's column may change decimals rather than widen, and
never gets narrower than the file's. A file with records marked deleted is
refused, as writing it again would drop them. Projecting edited shapes no
longer resets the progress total.

…t reads
A number is compared as the decimal its text says, not as an f64, so a
value past 2^53 that a read rounds is refused rather than written back
rounded. The record a publish leaves holds the digest of the file as it
reads (Synced.read, saved only when it differs from the layer's), so a file
that holds the layer as a Shapefile can (an empty text as no value) publishes
again. A code page RustGIS reads as UTF-8 for want of a decoder is refused.
Staged parts take the old parts' permissions before any content is written,
and text is cut to 254 bytes in the file's code page. A refused start says
so in the desktop app.

Walkthrough
GeoJSON-backed layers can now publish edits to their source through source.publish. The publisher checks source and rewrite fidelity, stages and reads back output, and replaces the source after a final check. The command, tests, user guide, and roadmap were updated.
Changes: GeoJSON source publishing
Layer / File(s)
Summary
GeoJSON reconstruction and fidelity checks crates/data/src/publish/json.rs
Rebuilds FeatureCollections, single Features, and bare geometries. Checks document structure, values, feature IDs, duplicate keys, and number text.
Publisher API and source replacement crates/data/src/publish.rs, crates/data/src/publish/json.rs
Exports the GeoJSON publisher. It validates the source and edited data, stages and reads back the output, rechecks the source, then replaces it. It returns publication metadata and notes.
Command integration and user-facing behavior crates/engine/src/cmd/publish.rs, crates/engine/src/tests.rs, docs/user-guide/index.md, ROADMAP.md
Selects the Shapefile or GeoJSON publisher on non-WASM targets. Tests cover publishing, sync state, and undo. The guide describes GeoJSON publishing, and the roadmap removes the planned source-file editing item.

Merge Risk: Low · up to 88861
GeoJSON publishing adds checks, staged validation and atomic replacement. A narrow residual risk remains: another program writing at the instant of replacement can be overwritten, and the replacement may not survive a power failure. The guide warns users about the first, and the second is deferred to a crate-wide follow-up. This is mergeable with owner awareness.

Explanation
The title names the main change: publishing a layer's edits back to its GeoJSON file. The changeset adds a GeoJSON publisher (crates/data/src/publish/json.rs), routes non-Shapefile sources in publish_work by the .shp extension, and updates the engine test and user guide to match. The title's #1385 reference is the linked issue, and the title is in the conventional feat(data) form.
Full details: Description check
Explanation
The description follows the template's Summary, Testing, UI evidence, and Related issue sections. The Summary explains what changes and why. Testing lists the commands and regression coverage run. UI evidence states that no visible UI change exists, which the template allows. Related issue reads 'Closes #1385.' The description is thorough and matches the raw summary and objectives. Minor gap: the Testing section cites test counts and CI results but does not give the exact command used, such as cargo xtask ci.
Full details: Linked Issues check
Explanation
Directly linked issue #1385 is open. Its requirements cover Shapefile and GeoJSON publishing. The PR objectives state that this PR delivers only the GeoJSON step and does not claim the Shapefile step, so Shapefile requirements are not assessed here. Coverage of the GeoJSON requirements, from the whole-PR summary and description (base d00276e to head 8886112):
Refuse when the source changed [#1385, step 1]: crates/data/src/publish/json.rs checks the source fingerprint and original read digest before writing, and rechecks the source before atomic replacement. The sync record comes from the existing source.syncState command.
Refuse what a rewrite would lose [#1385, step 2]: the publisher refuses foreign members, legacy crs, duplicate keys, dropped geometry or Z values, nested-property coercion, and number text that a rewrite would change. It validates output through the reader.
Keep the file's own choices [#1385, step 3]: collection names, document kind, and compatible feature ids are retained. Files with external IDs refuse row additions, removals, or reordering. Removed or renamed properties produce a notice.
Show sync state [#1385, step 4]: read-back rows update the existing sync record after success.
Bound to in-memory layers [#1385, step 5]: publishing is gated on the whole-read layer state.
Commands [#1385, step 6]: crates/engine/src/cmd/publish.rs dispatches to the GeoJSON publisher by a case-insensitive .geojson path.
Automated tests: eight GeoJSON publishing regressions in the data crate, and an engine test that publishes a GeoJSON edit, sets inSync, and undoes to edited.
Latest commit 8886112 [#1385, steps 2 and 3]: fixes row-change handling for mixed absent, null, and object properties in layers without fields. It refuses those row changes and adds a regression test.
Limits: I did not read the source hunks for this assessment. The verdict relies on the whole-PR summary, the description, the objectives, and the reported test results. Those inputs are author-provided or AI-generated. The PR description says 'Closes #1385', but the issue still contains Shapefile work. Closing the issue is a maintainer decision and does not change this GeoJSON verdict.
Full details: Out of Scope Changes check
Explanation
All reported changes map to the #1385 GeoJSON publishing step or its direct support:
crates/data/src/publish/json.rs: new GeoJSON publisher, including the mixed-properties row-change refusal added in 8886112. Implements the requirement.
crates/data/src/publish.rs: adds the json module, re-exports geojson, and updates module and Published documentation. Supports the publisher.
crates/engine/src/cmd/publish.rs: removes the Shapefile-only rejection and dispatches by extension. Needed to reach the publisher.
crates/engine/src/tests.rs: replaces the GeoJSON refusal assertion with a publish and undo test. Supporting test.
docs/user-guide/index.md: documents GeoJSON publishing, including the new restrictions. Feature documentation.
ROADMAP.md: removes the completed GeoJSON publishing item. Administrative, tied to this feature.
The refusal rules, including bbox, crs null, and mixed property shapes, are part of the publishing safety design for #1385. The summaries show no unrelated code changes. The summaries are AI-generated, and I did not check them against the full diff.

Performance (high confidence): both numbers are stringified before the a == b fast path, so every coordinate pays two allocations plus a decimal parse even when it is unchanged. keep_numbers runs in each of the three document calls per publish, so a large file pays this several times over. Checking a == b first gives the same result, because an equal Number takes the same *a = b.clone() either way.

Performance / peak memory (medium confidence):rebuilt is a whole serde_json::Value tree of the file and stays alive until geojson returns, alongside original, as_read, edited, written and read. For a large file (the reader accepts up to 256 MiB) that is one more full tree at peak. Scoping the check drops it as soon as the comparison is done, with no change in behaviour.

I reviewed the full 690-line diff against the PR head. I found no crash paths, no silent data loss, and no security problems. The GeoJSON publish path refuses every lossy rewrite I could construct, and the new else dispatch in engine/src/cmd/publish.rs only ever sees .geojson files, because record() gates on is_syncable and local_file. I posted two inline comments (performance and peak memory). Nothing else met the bar for an inline comment.
Bugs
None confirmed.
Checked and ruled out: a DateTime value can't reach a GeoJSON layer (the reader keeps GeoJSON dates as text, as dates_as_text_note assumes), and decimal() treats 1 and 1.0 as equal, so integer coordinates survive. The sync stamp is computed from the bytes being written, not the old file. The engine adopts only features, fields and CRS from the read-back, so the layer name is safe. (Confidence: high.)
Security
None found. Every get/zip/text.get path in json.rs is bounds-checked, and I found no unwrap, expect or indexing in non-test code. (Confidence: high.)
Performance
keep_numbers stringifies every number pair before the a == b fast path. Posted inline, with a suggestion. (Confidence: high.)
rebuilt keeps a full JSON tree alive to the end of the function. Posted inline, with a suggestion. (Confidence: medium.)
The publish parses and walks the file about nine times: serde, unique_keys, canonical_numbers, read_geojson, three document builds, the digests, and the read-back. This is linear in practice and runs off the UI thread with Cancel, so I'm noting it rather than asking for a change. (Confidence: medium.)
Quality
json.rs discards the ReadReport from both read_geojson calls. The round trip refuses the loss cases I traced (skipped features, dropped Z, swapped latitudes, unconverted features and CRS), so nothing is silent today. The protection is implicit, though. An explicit check that report.messages and report.skipped are empty on the original read would make it self-documenting. (Confidence: medium.)
json.rs names the dataset with file_name() (parcels.geojson), while read_path uses file_stem(). The name doesn't affect the sync digest or the engine, so it's cosmetic. (Confidence: high.)
stage_shapefile/unstage now stage GeoJSON too; the name is misleading. (Confidence: high.)
The read_geojson(...)? error paths in geojson don't carry the path or "nothing was written". Nothing has been written at those points, so this is wording only. (Confidence: high.)
document calls progress::begin three times per publish, which may reset the progress count. (Confidence: low.)
Per AGENTS.md, the Quality items above may wait for the release quality pass. None blocks merge.
AGENTS.md
Refusing bbox (collection-level and feature-level) and "crs": null is conservative, and it's documented. But RFC 7946 defines bbox as a standard member, and GDAL can write it. Many real files will be refused with "foreign members", which is a product gap rather than a bug. (Confidence: medium.)
The docs' UI labels ("Export Features", "Source File State", "Publish to Source") match the code.
The long_commands_stop_when_cancelled_while_they_run list needs no change, because source.publish is already registered.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Prevent external writes from being overwritten after the final check.
If another editor writes after Line 87, this rename overwrites that editor's changes. source_lock() only coordinates writers that acquire the RustGIS sidecar lock. std::fs::rename replaces an existing destination; it does not compare its current contents with the checked fingerprint. (doc.rust-lang.org)
Use a replacement protocol that preserves or rejects a concurrently changed destination, or coordination that covers all supported writers. Another fingerprint check before rename does not eliminate this interval.
Based on learnings, “atomic replace only guarantees the write itself is indivisible.”

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The quality points (checking the ReadReport explicitly, file_name vs file_stem, the stage_shapefile name now that it stages GeoJSON, error wording on the read paths, and the repeated progress::begin) are left for the release quality pass.
bbox and "crs": null are refused rather than silently dropped. Keeping bbox properly means recomputing it when geometry changes, which is a separate feature, so it's left for a follow-up.
On the additional finding about other programs writing after the final check: a rename can't compare the destination it replaces, and no portable lock binds programs that don't take it. The same boundary applies to the Shapefile publish. It's documented for GeoJSON now (a5b2bd6): the guide says other programs don't follow the lock and to stop other writers before publishing.
The reason will be displayed to describe this comment to others. Learn more.
Bug (low severity, confidence about 0.6): the properties template is looked up by output position (originals.get(i)), not by the original feature. In a layer with no fields, deleting or inserting a row moves each later row onto a different original's template. Example: source features [A (no "properties" key), B ("properties": null)]. Delete A, and B is written with its properties member removed, although the source had null. The read-back check doesn't catch it, because it rebuilds the edited output with the same shifted template, and the sync digest ignores property shape. Nothing is reported.
A small fix isn't obvious. Options: key the template by original row identity, which needs a stable row key the layer doesn't have; or refuse row-count changes whenever the originals' properties shapes differ.
The reason will be displayed to describe this comment to others. Learn more.
Confirmed and fixed in 8886112. In a layer without fields whose features mix absent, null and object properties, adding, removing or reordering rows is now refused, using the same row-change test as external ids. A row set that keeps every row in place, or a file where the shapes all match, still publishes. Regression: mixed_property_shapes_refuse_row_changes. The guide says so too.
The reason will be displayed to describe this comment to others. Learn more.
Performance / memory (medium-low confidence, not measured): the whole source is parsed into a serde_json::Value (original), and it stays alive until the function returns, alongside as_read (a Dataset), edited (a second tree), written and read. read_geojson streams features precisely so the document isn't held as JSON values, and this path undoes that. At the 256 MiB cap, the peak is probably several times the file size. The earlier thread about rebuilt is addressed. This one is about the trees that remain.
Direction: keep only what document needs from the original (per-feature id and properties shape, plus the top-level members), or drop as_read once removed and the digest are computed. Also, canonical_numbers (around line 259) allocates a String for every number in the file; comparing into a fixed stack buffer would avoid that.
The reason will be displayed to describe this comment to others. Learn more.
Left for the release quality pass. The peak is bounded by the reader's 256 MiB limit, publish runs off the UI thread with Cancel, and an out-of-memory failure happens before anything is written. Keeping only per-feature ids and properties shapes from the original, and comparing numbers without a String, are reasonable reductions to make together with measurement.
The reason will be displayed to describe this comment to others. Learn more.
Doc structure (low): this paragraph applies to both Shapefile and GeoJSON publishing, but it now sits under #### GeoJSON, so it reads as GeoJSON-only. Giving it its own heading fixes that:
Suggested change

#### Running a publish
On the desktop, make the layer active and choose **Publish to Source** in Command Search; it runs
Low severity, confidence about 0.6: in a layer with no fields, deleting or inserting a row shifts the properties template (null vs absent) onto a different original feature. The change is written without any notice, and the read-back check does not catch it. Inline at crates/data/src/publish/json.rs:138.
Low: a FeatureCollection that mixes "properties": null features with attributed features is refused as a whole. Null or absent properties are only kept when the layer has no fields, and the docs don't say so. The refusal text reads properties.value or size, which is unclear.
Security
None found. Source reads are size-capped, symlinks are refused, the lock is held through the rename, and the final source check runs before placement.
Performance
Medium-low confidence, not measured: the whole source is held as a serde_json::Value (original), alongside as_read, edited, written and read. At the 256 MiB cap the peak could be several times the file size, which undoes the streaming the reader does. Inline at crates/data/src/publish/json.rs:33.
Low: canonical_numbers allocates a String for every number (json.rs:259).
Quality
Low: docs/user-guide/index.md:498 now sits under #### GeoJSON but applies to both formats. Inline suggestion attached.
Nits, which may wait for the release quality pass: crate::io::stage_shapefile (json.rs:83) is reused for GeoJSON, so its name is misleading. Both reader ReadReports are discarded (json.rs:41, :60). The round trip covers content loss, but the swapped-latitude notice is dropped on success. Tests don't cover the positional template case or null properties.
AGENTS.md
No violations found. The new GeoJSON path uses the shared lock, the background path, Cancel checks in its loops, and refused messages that say nothing was written. Its doc comment states the single-step parts. The docs and ROADMAP changes match the code.
Earlier review threads (not re-raised)
4 earlier concerns left alone:
Number stringification before the a == b fast path: addressed in a5b2bd6.
rebuilt tree memory: addressed, since the rebuild is now scoped. The new memory point above is about the other trees.
Docs on external writers: addressed.
Parent-directory sync after rename: still open and unanswered, and the code is unchanged, so not re-posted.

… properties member
In a layer without fields, each row keeps its original's absent, null or object properties
by position, so adding, removing or reordering rows is refused when those shapes are mixed.
The guide says so, says null properties beside attributed features are refused, and gives
running a publish its own heading.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The properties template shift is fixed: a layer without fields whose features mix absent, null and object properties now refuses added, removed or reordered rows, and there's a regression test for it.
The guide now says absent or null properties are kept only in a layer without fields, so a collection that mixes them with attributed features is refused.
The publishing paragraph has its own heading.
Left for the release quality pass: the refusal text naming properties.value or size, the memory held by the parsed trees and the per-number String in canonical_numbers, the stage_shapefile name, and the discarded ReadReports.

Possible false refusal (medium confidence, about 0.6).serde_json's Number display uses ryu, and ryu writes any nonzero magnitude below 1e-5 in exponent form. A plain-decimal source value such as 0.000004 therefore reads back as 4e-6, and this check refuses the whole file. Values from 1e-5 upward (0.00001) pass. Coordinates close to 0 with many decimals are a realistic case. The refusal is consistent with the stated rule (number text a rewrite would change), but the doc's examples (1.00, 1E3) don't say it applies to small plain decimals too. Either document the case in docs/user-guide/index.md, or have the message name the spelling the writer would use (4e-6) so users know why the file was refused.
The reason will be displayed to describe this comment to others. Learn more.
Right: ryu writes magnitudes below 1e-5 in exponent form, so a plain 0.000004 falls under the "number text a rewrite would change" refusal. It's refused, not rewritten, so nothing changes silently. Naming the writer's spelling in the message, and adding small decimals to the guide's examples, is left for the release quality pass.
The reason will be displayed to describe this comment to others. Learn more.
Refusal text is unhelpful, and it refuses a common file shape (confidence about 0.7). A property column holding both numbers and text is read as Text (coerce in io.rs), so its numbers come back as strings. difference then returns the leaf value or size, and a user sees features.[0].properties.age.value or size. That covers a type change, not a size change. It is a correct refusal under the "never silent" rule, but users can't act on the wording. Suggest naming the member path only, and saying the type changed when a leaf's JSON types differ, for example "its value at features.[0].properties.age changes type". The docs also don't say that mixed-type columns can't be published.
The reason will be displayed to describe this comment to others. Learn more.
Agreed that the wording should say the type changed rather than "value or size", and that the guide could list mixed-type columns among what's refused. The refusal itself is correct and leaves the file unchanged, so this is left for the release quality pass.
The reason will be displayed to describe this comment to others. Learn more.
Reader report discarded (low severity, confidence about 0.5). The ReadReport from the reader is ignored here, and so is the one from the later read-back. When a file with feature ids has an unreadable-geometry feature, as_read has fewer rows than the source, so document reports "publishing added, removed or reordered rows couldn't preserve their identities". The user didn't add or remove anything. The refusal is still safe. Keeping report.messages and naming the unreadable features would make the reason accurate.
The reason will be displayed to describe this comment to others. Learn more.
Safe as noted: the file is refused either way. Carrying the reader's messages into the refusal, so an unreadable feature is named instead of "added, removed or reordered rows", is left for the release quality pass.
The reason will be displayed to describe this comment to others. Learn more.
Progress resets on every pass (low severity, confidence about 0.5).document runs three times per publish (the source rebuild, the edited document, and the read-back). Each run calls progress::begin(ds.features.len()), so the progress count goes back to zero and climbs again three times. The count is still accurate within each pass. Begin the counted step once per publish, or count the three passes as one step, so the progress bar doesn't repeat.
I found no data-loss, crash, or security defect. The write path refuses rather than guessing: it checks the source fingerprint and the original read digest, proves the original survives a read/write, validates the edited output through the reader, and keeps the source lock through the final atomic rename. The engine change is also sound. is_syncable limits recording to .shp and .geojson, so the extension branch in cmd/publish.rs covers every syncable file. No unwrap/expect/panic appears in non-test code, and no new dependency was added.
Bugs
None confirmed.
Security
None found in the changed lines. The .rustgis-lock sidecar is 0o666 (pre-existing in source_lock, not changed here). It is outside this PR's diff.
Performance
Four full-tree passes (parse, rebuild, edited document, read-back) remain. This is already raised in the memory thread, so I did not repeat it.
Progress resets three times per publish (json.rs:126, low, about 0.5). Inline comment posted.
Quality
Refusal wording for a type change reads …properties.age.value or size (json.rs:236, about 0.7). Inline comment posted.
The reader's ReadReport is discarded (json.rs:41, low, about 0.5). This can produce a misleading "rows added, removed or reordered" refusal when an unreadable feature has an id. Inline comment posted.
Quality-pass items, not posted: stage_shapefile is now also used for GeoJSON, and its error text says "Shapefile"; the keep_numbers progress check runs at every JSON node; the Published doc comment is slightly stale.
AGENTS.md
Possible false refusal (json.rs:270, medium, about 0.6): plain decimals below 1e-5 (e.g. 0.000004) are written by ryu as 4e-6, so the whole file is refused. The docs' examples (1.00, 1E3) don't cover this. Inline comment posted with a doc-or-message suggestion.
Mixed-type columns are refused and the docs don't say so. This is part of the same comment as line 236.
Concerns already raised in earlier threads that I left alone: 7 (the number-compare order, which is now fixed; the directory fsync, deferred by the author; the shifted properties template, now fixed; the Value-tree memory peak, deferred to the quality pass; the docs heading, now fixed; the rebuilt scope, now fixed; the external-writer docs, now fixed).
Four inline comments were posted, on crates/data/src/publish/json.rs lines 41, 126, 236 and 270.

Summary
source.publishnow writes edits back to a whole-read.geojsonsource, completing the GeoJSON step of #1385. The existingsource.syncStatecommand reports whether the layer, source, or both have changed.Before replacing anything, publish checks the source fingerprint and original read digest, proves the original document survives a read/write, and validates the edited output through the reader. Foreign members, legacy CRS declarations, duplicate keys, dropped geometry/Z values, nested-property coercion, and number text a rewrite would change are refused. Collection names, document kind, and compatible feature ids are retained; a file with ids refuses row changes that cannot preserve their identities. Removed or renamed properties produce a notice.
The file is staged beside its source with the existing permissions, synced and read back, then the source is checked again before atomic replacement. The shared nonblocking source lock coordinates RustGIS publishers. Read-back rows update the existing sync record after success. No new dependency or project-format field is added.
Testing
UI evidence
No visible UI change. This extends the existing Publish to Source and Source File State commands to another format.
