Dynamic imports can now be gated with --allow-unresolved (
8d32227)
Bun’s bundler now has a new allowUnresolved option and matching CLI flag to control which non-literal import(), require(), and require.resolve() calls are allowed through. It extracts template-literal “shapes” and matches them against glob patterns, making dynamic import behavior explicit instead of all-or-nothing.
HTML-referenced assets are now included in bundle manifests (a6fe20e)
Assets referenced directly from HTML tags like <link rel="icon"> and <img> were being emitted but omitted from the manifest’s files array, which could make Bun.serve() return 404s for them. This fix makes HTML asset tracking follow all import records so referenced files stay live and appear in the manifest.
SQL queries now error cleanly past PostgreSQL’s 65,535-parameter limit (d5d842d)
Large batch inserts no longer crash with a Zig cast panic when they exceed the wire protocol’s 16-bit parameter limit. Bun now validates counts up front and returns a descriptive ERR_POSTGRES_TOO_MANY_PARAMETERS instead, which is much easier to diagnose and recover from.
Blob sizing no longer breaks pipe-backed stdin reads on Linux (e2b0d24)
Bun.stdin.exists() and Bun.stdin.size were causing non-seekable stdin streams to be treated like empty files because resolveSize() fell through to size = 0. The fix preserves the unknown-size sentinel for pipes and FIFOs, restoring Bun.stdin.stream()/text() behavior.
Windows path resolution and exit handling are safer (f70cca3, b2e657e)
Bun now returns ENOENT instead of panicking when Windows realpath/readlink unexpectedly yield a null pointer. It also switches process termination to TerminateProcess() to avoid NAPI addon crashes during DLL_PROCESS_DETACH cleanup.
Other misc changes
- Windows null-pointer guards in
realpath/readlinkand safer process exit handling. - Regression tests added for stdin/blob sizing, SQL parameter overflow, HTML manifest assets, and dynamic unresolved specifiers.
- Minor internal refactors and type/API plumbing for the new bundler option.
