Every pull request of mine merged into a public repository outside my account between October 26, 2025 and October 26, 2026. Titles are shortened from the pull requests, and each type comes from the title's prefix (fix, feat, perf) or, when it has none, its wording.

    Keep new sparse search corpora from sharing an index name

    New sparse search indexes were named after the current second, so two created in the same second collided: Qdrant rejected the second one, and Elasticsearch and OpenSearch deleted the first index and replaced it. Names now end in a UUID, the helpers no longer delete a colliding index, and reusing an existing index works as before.

    The test freezes the clock and runs two builds against one real in-memory Qdrant database. Elasticsearch and OpenSearch got source review, not live-server tests.

    Remove quadratic list-boundary copying

    To find where each list item ended, the materializer sliced the rest of the item list on every pass (seeds[index + 1:]), so a flat list of n items copied about n²/2 references. One backward pass with a monotonic stack now finds every item's end, and each item enters and leaves the stack once. Offsets and nesting are unchanged.

    12 focused regression tests on synthetic lists, and the full suite passed with 21,548 tests and no failures. Building the text slices still scales with their total size, so I didn't claim a production speedup.

    Shuffle complete label groups before trimming odd rows

    The group-by-label batch sampler dropped the last row of every odd-sized label group once, in the constructor, before any shuffling, so that row could never be picked for training. It now keeps every group whole, shuffles each epoch, and only then trims to complete pairs, so the row left out changes from epoch to epoch.

    Over ten seeded epochs every row appears, each epoch matches len(sampler), and the same epoch replays identically. Both tests failed on the old code.

    Handle concurrent cache invalidation

    The evaluation cache checked path.exists() and then opened the file, so an entry invalidated by another process in between raised FileNotFoundError instead of counting as a miss. The loader now opens the file directly and treats only a missing file as a miss, so every other read error still surfaces.

    Eight deterministic tests stage the race by coordinating the file operations directly, with no sleeps and no model data.

    Stack tensor-formatted labels in the data collator

    Offline embedding distillation stores teacher embeddings in the label column. After dataset.with_format("torch") each label is a tensor, and the shared data collator crashed before the first training step. The collator now stacks tensor labels with torch.stack and leaves plain Python labels on the old path.

    The fix is in the base collator, so the SentenceTransformer, SparseEncoder and MultiVectorEncoder collators all inherit it. The PR includes a minimal reproducer.

  • Bug fixmaziyarpanahi/openmed#3276Merged Sep 21, 2026

    Reject non-finite keep-alive durations

    The cache keep-alive parser accepted NaN and infinite durations, and very large integers could escape as an OverflowError. The fix rejects non-finite values and conversion overflow while keeping valid durations and the explicit no-expiry opt-outs working.

    39 focused regression tests pass on the branch, and 14 of them fail against the original code.

  • Bug fixmaziyarpanahi/openmed#4223Merged Oct 17, 2026

    Read JSONL records without splitting Unicode inside strings

    The JSONL loader split files with str.splitlines(), which also breaks on Unicode separators such as U+2028 that JSON allows inside strings, so a valid record could be cut in half and rejected. The loader now reads the file's physical lines, and blank lines, error line numbers and object_pairs_hook behave as before.

    14 focused tests, 9 of which fail on the old code. The full suite passed with 29,620 tests and no failures.

  • Bug fixmaziyarpanahi/openmed#3520Merged Sep 27, 2026

    Isolate cached GLiNER models by device

    The model cache key ignored the requested device, so loading the same GLiNER model for a second device could move the instance a previous handle was still using. The device is now part of the cache key and placement happens inside the cached loader.

    Covered by nine focused tests with model doubles. It hasn't been run or benchmarked on a real GPU.

    Fingerprint federated update schemas

    Adds a domain-separated SHA-256 fingerprint of an already-validated federated update's schema (model digest, adapter format, parameter names and shapes), plus a constant-time comparison. Tensor values and per-update content are excluded from the hashed bytes.

    A matching fingerprint shows that two updates share a schema. It doesn't show that an update is safe or private. I disclosed AI assistance in the PR.

    Cover client context-manager cleanup

    Offline tests for the Cyberwave Python SDK's context manager: entering returns the same client, disconnect runs exactly once on both normal and exceptional exit, and exceptions raised inside the block propagate.

    Tests only: the SDK's behavior is unchanged, and nothing ran against real hardware. I disclosed AI assistance in the PR.

    Export JSON schemas for private-training metadata

    I compared another contributor's JSON schemas with OpenMed's Python validator and flagged two cases the schema accepted but the validator rejects: a suppressed participant band that still carried values, and confidence levels outside (0, 1). The maintainer's follow-up added those conditions with negative tests before merging on October 11, 2026.

    A review of someone else's pull request, so it isn't counted among mine. I disclosed AI assistance in the review.
