From 34253e33c092324f6cdcf92637a3849e6ab0e750 Mon Sep 17 00:00:00 2001 From: Yury Fedoseev Date: Fri, 22 May 2026 17:36:20 -0700 Subject: [PATCH] =?UTF-8?q?release:=20v0.3.53=20=E2=80=94=20Java=20binding?= =?UTF-8?q?=20(8th),=20OCR=20parity,=20markdown-extraction=20quality=20pas?= =?UTF-8?q?s?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Released 2026-05-22. ## Java is the 8th binding (fyi.oxide:pdf-oxide:0.3.53) Native Maven-Central JNI binding on jni-rs 0.22, JDK 11 LTS floor, five-arch fat JAR (linux x86_64/aarch64, macOS x86_64/aarch64, windows x86_64). Full v0.3.52 surface parity across text / markdown / AutoExtractor / forms / render / PAdES B-B+B-T+B-LT / destructive redaction / split-by-bookmarks / compliance / crypto-policy. Free Kotlin interop via the same JAR. New `pdf_oxide_jni` workspace crate; CI `java` + `fips-java` jobs; release `build-java-native` + `package-java-jar` + `publish-maven` (autoPublish=false per the release gate). 52 JNI symbols, 9 wired classes, 82 JUnit tests. ## OCR parity across all prebuilts The published Python wheels (glibc + musl) and the Java JAR now build with OCR — previously CI tested `--features python,ocr,barcodes` but release.yml shipped `--features python`, so PyPI users got no OCR. Java JNI now builds the full ocr,rendering,signatures,barcodes, tsa-client,system-fonts set, matching the Node/Go/C# native cdylib. FIPS variants deliberately exclude OCR. ## Markdown-extraction quality pass Root-cause fixes (with regression tests + a 70-PDF baseline-vs-HEAD sweep gating every reading-order/table change): - Table cells preserve bold/italic — tagged-PDF table_extractor now populates cell.spans instead of joined-text-only. - CamelCase brand names no longer split ("SalesForce", not "SalesF orce") — repairs TJ-kerning misread as a word space, ASCII lower→UPPER signature in sparse-width spans only; all-caps and acronyms untouched. - Spatial cell words no longer fragment into per-word columns — row-coverage phantom-column filter, gated so it only refines an already-detected table and never fabricates one from prose. - Centered titles read in document order — centered-block guard in XY-cut keeps small centered blocks single-column. - Fewer fragmented headings (word-per-heading + wrapped); KPI numeric-only heading runs collapse to a list; stray pipes escaped. - Content-preservation policy: post-processing never drops/rewrites legitimate text. Band-aids that filtered page-numbers, rewrote bullet codepoints, flattened sparse-real tables, or deduped repeated content were removed after the sweep proved they damaged real documents. ## Review nits (PR #533) Doc accuracy (DocumentEditor/Pdf Cleaner backstop, arch counts), PageClass enum parity with Rust PageKind, annotations.rs dead-code, PdfPage stale Javadoc. ## CI / Release hygiene - Composite action .github/actions/free-disk-space (single source of truth; swap-storage:false locked in; df -h diagnostics) replaces 6 drifted callsites — fixes the Code Coverage OOM on PR #533. - macOS FIPS Java deferred (documented UnsatisfiedLinkError). ## Known issue Tight two-column PROSE bodies can still interleave in reading order (#534). A safe fix needs a table-vs-prose classifier; two attempts (valley-threshold + structural detector) were reverted after the sweep caught table-data corruption — both documented inline in xycut.rs. ---

Both glibc and musl Python + wheels, and the Java JNI fat JAR, now build with OCR for parity with + the Node / Go / C# prebuilts. FIPS variants deliberately exclude OCR + (no ONNX in FIPS deployments). + +- **Markdown table cells preserve bold/italic** — the tagged-PDF table + extractor built `TableCell`s from joined text only, discarding the + per-span font weight/style, so `**bold**` / `*italic*` inside table + cells was lost on the way out. Cells now carry their span styles + end-to-end (`table_extractor` populates `cell.spans`). + +- **Words no longer split mid-word by phantom spacing** — words whose + glyph runs are positioned edge-to-edge (common in presentation + exports) could be emitted with a spurious internal space when the + source font lacked a `/Widths` array. Per ISO 32000-1 §9.4.4, + inter-glyph spacing is the displacement between glyph origins; the + fallback-width correction that compensates for missing width metrics + now applies only when glyph boxes actually overlap, never to + cleanly-adjacent glyphs. Legitimate word spacing — including after a + token that ends in a capital letter — is preserved. + +- **Spatially-positioned cell words no longer fragment into columns** — + a single table cell whose words are laid out with wide gaps was split + into one column per word. A row-coverage filter drops phantom columns + present in too few rows, gated so it only refines an already-detected + table and never fabricates one from prose. + +- **Prose pages no longer mis-detected as tables** — a single-column + page whose wrapped paragraph lines' inter-word gaps coincidentally + aligned could be emitted as a fragmented table. A prose gate rejects a + spatially-detected (no-rulings) table when a row crosses a sentence + boundary, a structure genuine data tables do not exhibit. Ruled and + tagged tables are unaffected. + +- **Centered titles read in document order** — a centered multi-word + title plus subtitle/byline was misread as multiple columns, + scrambling the heading. A centered-block guard (scattered leftmost + edges, small block) keeps such blocks as a single column. + +- **Fewer fragmented headings** — runs of same-level heading fragments + (PowerPoint word-per-heading exports, wrapped headings) are merged + when the run is unambiguous; KPI numeric-only heading runs collapse + to a list. + +- **Stray pipe characters escaped** — a `|` outside a markdown table + block is escaped so downstream renderers do not misread it as a + malformed table row. + +- **Content-preservation policy for markdown post-processing** — the + post-process pass never drops or rewrites legitimate text. Earlier + band-aids that filtered "Page N" lines, rewrote bullet-glyph + codepoints, flattened sparse-but-real tables, or deduped repeated + content were removed after a 70-PDF baseline-vs-HEAD regression sweep + proved they damaged real documents; the correct upstream fixes are + tracked as follow-ups. + +### Known issues + +- Tight two-column **prose** bodies can still interleave row-by-row in + reading order + ([#534](https://github.com/yfedoseev/pdf_oxide/issues/534)). A safe + fix needs a table-vs-prose classifier so it does not regress + table-cell ordering; two threshold/structural attempts were reverted + after the regression sweep caught table-data corruption. + +- Bullet and ligature glyphs in fonts with no usable `/ToUnicode` CMap + can decode to an incorrect code point or be dropped + ([#535](https://github.com/yfedoseev/pdf_oxide/issues/535)). The fix + is a §9.10 decode fallback (glyph-name / encoding) in the font layer, + not a markdown-layer code-point rewrite (which was removed as content + corruption — see the content-preservation note above). + +### CI / Release + +- **`.github/workflows/ci.yml`** — new `build-lib` variant + `java-jni` builds the JNI cdylib with `--features rendering, + signatures,tsa-client`. New `java` job (matrix: ubuntu × JDK + {11, 17, 21}) downloads the native, stages into the Maven + resource path, runs `mvn compile/test/package`, validates JAR + contents + manifest, uploads the JAR artifact. New `java-lint` + job runs the Java code-quality gates — Spotless + (palantir-java-format) formatting check and SpotBugs static + analysis — bringing the Java binding to parity with the + format+lint gates the other bindings already enforce (rustfmt + + clippy / gofmt + golangci-lint / Biome / dotnet-format / ruff). + +- **`.github/workflows/ci-fips.yml`** — new `fips-java` job + (ubuntu + macOS) builds `pdf_oxide_jni` with `--no-default-features + --features fips,signatures` and runs the full JUnit suite against + the FIPS-compiled cdylib. Validates the `legacy-crypto` exclusion + holds end-to-end. + +- **`.github/workflows/release.yml`** — new `build-java-native` + matrix (5 arches: linux x86_64/aarch64, macOS x86_64/aarch64, + windows x86_64) cross-compiles the JNI cdylib per target with + `ocr,rendering,signatures,barcodes,tsa-client` (OCR-enabled parity + with the Node/Go/C# native cdylib; `system-fonts` arrives + transitively via `rendering`). New + `package-java-jar` job assembles the fat JAR (all 5 natives + embedded). New `publish-maven` job uploads to Maven Central via + `central-publishing-maven-plugin` with `autoPublish=false` per + `feedback_release_gate` — the upload reaches `VALIDATED` state and + the maintainer flips Publish from the Central Portal UI.
