Add reportlab and svglib PDF-generation libraries#64
Merged
Conversation
Add two PDF-generation libraries to the executor bundle: - reportlab (>=5.0.0, BSD): the standard library for programmatic PDF generation. Pillow is already bundled, so this adds only 1 package. - svglib (>=2.0.2, LGPL-3.0): converts SVG into ReportLab drawings, giving a clean path from matplotlib SVG output to PDF. Adds 4 small pure-Python deps (cssselect2, tinycss2, webencodings + itself). Skipped xhtml2pdf (HTML->PDF): it pulls ~20 packages including a PDF-signing/crypto stack (pyHanko, oscrypto, asn1crypto) and pins reportlab<5, which is at odds with the "lightweight" goal. svglib's LGPL-3.0 license matches the existing fpdf2 dependency, so it introduces no new licensing posture. Bump executor 0.4.4 -> 0.4.5. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Keep code-interpreter in sync with the executor version bump: update code-interpreter/pyproject.toml, its uv.lock, and the Helm chart version from 0.4.4 to 0.4.5. Matches the release convention from #63. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

What
Adds two PDF-generation libraries to the
executordependency bundle:>=5.0.0>=2.0.2cssselect2,tinycss2,webencodings) — SVG → ReportLab drawings, a clean path from matplotlib SVG output to PDFNet: +5 pure-Python packages.
Version bump (kept in sync)
The
executorandcode-interpreterpackages are released together, so this bumps all of them0.4.4 → 0.4.5, matching the release convention from #63:executor/pyproject.toml+executor/uv.lockcode-interpreter/pyproject.toml+code-interpreter/uv.lockkubernetes/code-interpreter/Chart.yamlWhy these two
reportlabwas the explicit ask and is essentially free given Pillow is already present.svglibcomplements it (and the existing matplotlib stack) by rendering SVG straight into PDFs, with a negligible footprint.What was deliberately skipped
pyHanko,oscrypto,asn1crypto,requests/urllib3), and pinsreportlab<5. Fails the "lightweight" goal.Licensing note
svglibis LGPL-3.0, which matches the existingfpdf2direct dependency (also LGPL-3.0-only) — so it introduces no new licensing posture. The image only invokes the library (no modification/redistribution of source). No GPL/AGPL anywhere in the dependency tree.Verification
