- ⚡ Fun fact — I have upstream code merged at Google (Gson), Microsoft (Playwright, GitHub spec-kit, EF Core), the Apache Software Foundation (Maven), Red Hat (Quarkus), the OpenJS Foundation (Jest) and LangChain — and my Jest fix shipped in v30.5.1, credited by name in the release notes.
Upstream contributions to projects I actually use in production.
| # | Project | Stars | Contribution |
|---|---|---|---|
| 1 | 24.2k |
#3112 — a ? extends Base element type was serialised from the declared type, so subclass fields vanished, and a List<? extends CharSequence> came out as [{},{}] with the strings gone entirely. Merged by a Gson maintainer after it passed Google's internal tests |
|
| 2 | OpenClaw | 390.2k |
1bf5fb6 — the macOS Talk overlay was hidden by a dismissal that had already been interrupted. My #132565 was superseded, and the fix shipped carrying my Co-authored-by. Released in v2026.9.1 |
| 3 | 138.2k |
#4356 — command-ref tokens could not hold a hyphen, so a bundled command was unreachable. Chosen as the canonical fix for #4198 over two competing PRs | |
| 4 | 138.2k |
#4367 — check-prerequisites exported the spec path but never checked the file existed, so later phases failed with no guidance |
|
| 5 | 96.5k |
#42449 — the UI-mode filter summary was a plain div, so it could not be reached or opened from the keyboard |
|
| 6 | 14.8k |
#38880 — pruning a pooled SQLite connection could kill the process from a native callback, because the rollback hook was cleared through a handle that was already closing | |
| 7 | 14.8k |
#38971 — ExecuteNonQuery and ExecuteScalar reported success when a later statement failed, and a busy commit after RETURNING was retried with a second sqlite3_reset, which answers OK once the first has reported the busy, so the write was rolled back with no error at all. Merged into 12.0-preview1 |
|
| 8 | 14.8k |
#38976 — reading a stream from a SQL expression handed three nulls to sqlite3_table_column_metadata, which answers SQLITE_MISUSE, so GetStream threw as soon as another expression column shared the query. Open since April 2022. Merged into 12.0-preview1 |
|
| 9 | 14.8k |
#38875 — a named default constraint was carried onto the temporal history table. Approved by a second EF Core team member after the AlterColumnOperation case the original tests did not reach. Merged into 12.0.0 |
|
| 10 | 11.5k |
#3242 — --affinity could not address a CPU above the 32nd, and the 64th threw an unhandled OverflowException on a 32-bit host instead of a normal option error |
|
| 11 | 146.8k |
#39978 — removed a contradictory duplicate block from the Groq with_structured_output docstring |
|
| 12 | 45.5k |
#16413 — a leading # was read as a URL fragment, so every package imports subpath broke under ESM. Shipped in v30.5.1 |
|
| 13 | 5.4k |
#13055 — the concurrent builder caught Exception, so a step throwing an Error printed BUILD SUCCESS while nothing had been built. A reviewer reproduced it and found a second failure wrapped the error in a checked exception, so the halt decision now reads the failures themselves |
|
| 14 | Scrapy · parsel | 1.4k |
#367 — pinned how C1-range numeric character references extract, gated on the libxml2 version that implements the mapping rather than branching the expectations |
| 15 | 15.9k |
#56360 — @WithFormRead request filters were moved after the body handler in reverse order, so their priorities were applied backwards. Merged by a Quarkus maintainer |
| Project | Contribution |
|---|---|
| #20128 · #20129 · #20130 — nested emphasis around a bare URL turned into strong emphasis, a conditional comment printed its borrowed tag markers twice and invented text, and a JSX comment that moved on every run, open since 2017 | |
aws-cli#10677 · aws-cdk-cli#1988 — --generate-cli-skeleton output failed validation on its own sample data for 4,638 of 17,737 operations, open since 2017; and cdk import submitted the template CloudFormation mangles, so the import failed naming a resource nobody touched |
|
#158437 · #158503 — a malformed SQL cursor came back as a raw JVM error, and setting similarity on an nvidia embedding endpoint always threw a 500 |
|
#68035 · #68036 — an Enum subclass is iterable but is_list_like said otherwise so it could not be used as columns, and MultiIndex.factorize rebuilt its uniques from tuples, silently dropping extension dtypes and level names |
|
#26100 — fcluster read one slot past the end of its criterion array, so maxclust with t=0 returned whatever was in that memory |
|
#7692 — DataFrame.Join and Merge spun forever when both suffixes were the same string, open since 2022 |
|
| mypy | #21941 — stubtest aborted the entire run when a classmethod's first parameter wasn't named cls, taking out stub checking for a whole distribution |
| Tailwind CSS | #20436 — the v4 upgrade codemod rewrote a React variant prop as a utility class |
| Chart.js | #12292 · #12293 — a legend key that did not match the line it stood for, and a fractional-canvas resize regression |
| #1840 — silenced a publish warning for the shaded variant | |
| Netty | #17389 — a form field still being decoded was in neither list destroy() clears, so a client that goes away mid-upload leaked the field and its slice of the inbound buffer. Vert.x installs the exact factory configuration this fires in |
