bunfig: apply telemetry = false in every command that reads the file - #40728
With telemetry = false in bunfig.toml, a crash under bun test, bun build or bun install still starts curl -fsSL https://bun.report/<trace>/ack. bun run does not.
Cause: Parser::parse (src/bunfig/bunfig.rs:443) applied the key only for RunCommand and AutoCommand.
Fix
Parser::parse reads telemetry for every command that reads the file, before anything in it can fail. Any value but true turns the upload off.
bun_analytics keeps one flag that config can only set. telemetry = true turns nothing back on. The docs state the rule and its reach.
bun lint and bun fmt pass the opt-out to the process that reads an ESLint or Prettier config.
Verified: test/config/bunfig/telemetry.test.ts. Self-reviewed: 30 concerns raised, 28 addressed (see notes).
Background
The crash handler asks bun_analytics::is_enabled() before an upload. Canary builds upload on every OS, releases on macOS and Windows.
Debug and ASAN builds return before that check, so the test reads the value through a new test-only binding, crash_handler.isAnalyticsEnabled().
Considered a wider command list (6 of 9 tags), and keeping the tri-state (a project true would undo a global false).
Downsides
telemetry = true overrides neither DO_NOT_TRACK=1 (as since v1.4.0) nor HYPERFINE_RANDOMIZED_ENVIRONMENT_OFFSET (new). This declines the requested TriState::Yes => true. A maintainer must confirm it.
Cost: one more root-key lookup per parsed bunfig outside run (89 instructions at 1 key), and 2,048 bytes of release .text.
bunx, bun exec, compiled executables and the global file under run, test and build still need DO_NOT_TRACK=1.
Notes
This PR was reworked. It first set TriState::Yes => true (bunfig wins over DO_NOT_TRACK). A review objected: bunfig.toml is a project file, so a cloned repository could turn uploads back on over a user's DO_NOT_TRACK=1. The request allowed the other order if the docs state it. The PR now keeps that order, states it in the docs, and fixes a second report: bun test ignores telemetry = false.
The rule. Uploads are off when any of these holds: a telemetry that is not true in a bunfig the process reads, DO_NOT_TRACK, or HYPERFINE_RANDOMIZED_ENVIRONMENT_OFFSET. Nothing turns them back on.
A telemetry that is not a boolean. This PR adds no type error: only bun <file> and bun run check the type, as on main. Everywhere the value counts as an opt-out. GitHub code search finds public bunfig.toml files with a [telemetry] table (5 of 541 sampled, for example enabled = false). A type error for every command would take their bun install, bun test and bun build from exit 0 to 1.
What the setting does not reach (same on main; the docs now list these)
bunx and bun exec: they apply no bunfig. A reader for this one key costs an openat and an allocation on every start.
An executable built with bun build --compile started outside the project directory.
DO_NOT_TRACK=1 in a .env file: the program reads "1" and the upload still starts. Handed off as its own task.
With Bun as node --config=<file>, preload, smol and serve.port are still dropped. This PR fixes only telemetry on that path. Handed off as its own task.
The crash output does not say whether a report was uploaded.
Measurements. Taken before the rebase onto 2596ac5. Debug builds: main 7ca0042 plus the test binding, against the PR at that base. Release builds: LTO canary builds of main 7ca0042 and of the PR at that base.
root-key lookups per parsed bunfig: bun <file> 21 -> 21, bun run x.js 21 -> 21, bun test 18 -> 19, bun build 14 -> 15, bun install 17 -> 18 per file; no bunfig: 0 -> 0 parser entries (gdb counter, debug build)
telemetry lookup on test/build/install: 89 instructions at 1 key, 251 at 10, 971 at 50 (gdb stepi count, release profile build); bun <file> and bun run: +0 lookups
opens of bunfig files: bun -e 1 1 -> 1, bun test 1 -> 1, bun install 2 -> 2, bun exec true 0 -> 0 (gdb catch syscall openat)
host functions: +1 (crash_handler.isAnalyticsEnabled, bun:internal-for-testing only), 295 B over 2 symbols, no data or rodata section change, 0 startup work
crash path: is_enabled 56 -> 39 instructions (the PR count is the binding that holds the inlined body), stores to analytics state 1 -> 0 (llvm-objdump, release profile build)
is_enabled() matrix (command x bunfig x env): 6 of 48 cells wrong on main, 0 of 48 on the PR (debug build)
uploads attempted with a telemetry that is not true in a bunfig the process reads: 12 of 15 rows on main, 0 of 15 on the PR (canary release builds, fake curl first on PATH)
exit code with telemetry = "no": unchanged for all 11 probed commands (bun test, bun build, bun install, bun lint, bun fmt, node --config stay 0; bun -e 1 and bun <file> stay 1)
Tests
bun bd test test/config/bunfig/telemetry.test.ts: 19 pass, 11 skip. On main plus the binding 12 of 19 fail, each by its assertion.
The crash rows run only on builds that upload without being asked (canary, and releases for macOS). There a fake curl stands first on PATH. Canary release build of the PR: 27 pass, 1,249 of 1,250 runs (950 alone, 300 with --parallel). The one failure was an 18 s stall of the machine against the 5 s default timeout. Canary release build of main: 22 of 27 fail, 18 for the missing binding and 4 crash rows (bun test, bun build, bun install, global file plus project file).
These rows have run on linux x64 only.
bun compile has no row. Macros are disabled there, so it runs no JavaScript of the project in its own process.
Also run: test/config/bunfig/, test/cli/install/bun-run-bunfig.test.ts, test/cli/run/run-crash-handler.test.ts (debug), and test/cli/lint/bunfig.test.ts, test/cli/lint/config-files.test.ts, test/cli/lint/js-plugins.test.ts, test/cli/format/bunfig.test.ts (release).
Self-review, not taken
Concurrent binding rows. Under a debug build each row takes 1.0 to 1.8 s, and six together took up to 4.5 s against the 5 s default timeout. They run one at a time; a comment in the test says so.
A tracking issue for the cases the setting does not reach. The docs list them, and the two that look like defects were handed off.
Other open PRs.#46007 edits Parser::parse at the define and smol blocks, not here. #39965 edits the same docs section.
Telemetry configuration now sets a process-wide analytics opt-out for applicable commands. Analytics status also reflects environment variables. The crash-handler API exposes that status, and lint propagates disabled analytics to child processes. Documentation and tests describe and check these behaviors.
Configuration parsing sets a one-way analytics opt-out when applicable. Analytics status also checks DO_NOT_TRACK and HYPERFINE_RANDOMIZED_ENVIRONMENT_OFFSET. The documentation describes which configuration files apply and how telemetry settings relate to environment variables.
Runtime status and child-process propagation src/runtime/api/crash_handler_jsc.rs, src/runtime/api/crash_handler_jsc.bind.ts, src/runtime/cli/lint_command.rs
The crash-handler API exposes analytics status. The lint command sets DO_NOT_TRACK=1 in the child environment when analytics are disabled.
Command and crash-upload coverage test/config/bunfig/telemetry.test.ts
Tests cover analytics status across command contexts, environment overrides, invalid telemetry values, and eligible crash-upload scenarios, including bun install.

Merge Risk: Low · up to ca35e
The change improves telemetry opt-out handling, but nested auto-install configuration still has a narrow opt-out gap, and the global configuration guidance overstates bunx coverage. Tests also retain assertion and timeout-cleanup gaps. These are bounded concerns requiring owner awareness and follow-up.

Explanation
The title names the main change: the bunfig telemetry = false setting now applies in every command that reads the file, not only bun run and bun <file>. The raw summary and objectives confirm that Parser::parse now reads telemetry before other parsing for all commands, and that the PR also changes the analytics opt-out flag and docs. The title covers the central fix, so it passes.
Full details: Description check
Explanation
The description follows the template, with a problem and fix, verification steps, and background. It names the test file, the measured results, and the known limits (for example bunx, bun exec, and .env cases). The 'What does this PR do?' and 'How did you verify your code works?' content is present in substance, though not under those exact headings. Its length and detail go beyond the template, but the required information is there, so the check passes.

Status at ca35eac: this PR was reworked. It no longer lets telemetry = true override DO_NOT_TRACK=1. It now applies telemetry = false in every command that reads the file, and any opt-out wins.
How the defect was reproduced, on a canary release build of main with a fake curl first on PATH (nothing reaches bun.report):
bunfig.toml holds telemetry = false. A crash under bun test, bun build or bun install starts curl -fsSL https://bun.report/<trace>/ack. A crash under bun run or bun <file> starts nothing.
With this branch none of them starts it. Of 15 probed rows with a telemetry that is not true, 12 upload on main and 0 on the branch.
The PR body notes list three decisions for a maintainer: the precedence rule, the scope beyond bun run, and what a telemetry that is not a boolean does.
Debug and ASAN builds return from is_reporting_enabled() before the
analytics check, so a test cannot observe the bunfig telemetry setting
through a crash. The binding returns bun_analytics::is_enabled().

Honor telemetry in auto-install configuration files.
When runtime auto-install reads a project or importer bunfig.toml outside the startup directory, it ignores telemetry = false. A later eligible crash can upload a report despite the documented opt-out. Honor that setting on this path while preserving the documented bunx exception.

Add coverage for analytics state on early exit.
If bun run exits before a.js, told() returns stderr. The negative assertion can then pass without observing analytics state. Add a direct state or crash-upload observation for that path.

The `telemetry` key was applied only for `bun run` and `bun <file>`.
`bun test`, `bun build`, `bun compile`, the package manager commands,
`bun lint`, `bun fmt` and bun as `node --config` parsed the file and
dropped the key, so a crash still uploaded a report.
Parser::parse now reads the key on every parse but the `[install]`-only
one, before anything in the file can fail. A value that is not `true`
turns the upload off. The type check stays where it was, for `bun run`
and `bun <file>`, so no command gets a new error.
bun_analytics keeps one set-only flag in place of the tri-state. A
`telemetry` that is not `true`, DO_NOT_TRACK or
HYPERFINE_RANDOMIZED_ENVIRONMENT_OFFSET each turn the upload off, and
`telemetry = true` turns nothing back on.
`bun lint` and `bun fmt` read an ESLint or Prettier config in a second
process, which reads no bunfig.toml. They pass the opt-out to it as
DO_NOT_TRACK=1.
The reason will be displayed to describe this comment to others. Learn more.
🟣 pre-existing, not blocking: Users who put telemetry = false in the global .bunfig.toml still get a crash report uploaded from bunx, although the docs now say that file counts for it. The Counts::OnlyInstall arm at src/bunfig/bunfig.rs:411 returns None, and that is the parse bunx uses on the global file through load_user_install_section (src/bunfig/arguments.rs:201, called from src/install/PackageManager.rs:1976). Fix: apply the opt-out in every parse of a file the process reads, including the OnlyInstall one, so both the global file under bunx and the nearer-directory files under auto-install (src/install/PackageManager.rs:3024) count; or else drop bunx from the global-file sentence at docs/runtime/bunfig.mdx:21, which currently contradicts docs/runtime/bunfig.mdx:127. A small fix can ride a push you are already making; otherwise a short reply is enough.
Why this was flagged
A user sets telemetry = false in ~/.bunfig.toml and runs bunx <pkg> on Linux or macOS. src/runtime/cli/bunx_command.rs:1193 calls user_cache_directory, which at src/install/PackageManager.rs:1976 calls load_user_install_section; that reaches Parser::parse with Counts::OnlyInstall (src/bunfig/bunfig.rs:1392). The new code at src/bunfig/bunfig.rs:409-412 maps Counts::OnlyInstall to None, so opt_out_by_config() is never called even though the file was opened and parsed. If the bunx process crashes, bun_analytics::is_enabled() at src/crash_handler/lib.rs:3027 still returns true and the report uploads. The base branch behaves the same for bunx, so the upload itself is pre-existing, but the PR's stated rule is that any bunfig the process reads counts, and docs/runtime/bunfig.mdx:21 now lists bunx among the commands that read the global file and says telemetry = false in either file counts, while docs/runtime/bunfig.mdx:127 says the setting does not reach bunx.
Verification: A user with telemetry = false in ~/.bunfig.toml runs bunx <pkg> on Linux/macOS and the bunx process itself crashes. At src/bunfig/bunfig.rs:409-415 the OnlyInstall arm yields None, so opt_out_by_config() is never called even though the whole file is in json. The base ignored it on this path by the same route, so pre-existing. docs/runtime/bunfig.mdx line 21 is false for bunx under the current code.

telemetry = trueoverrides neitherDO_NOT_TRACK=1(as since v1.4.0) norHYPERFINE_RANDOMIZED_ENVIRONMENT_OFFSET(new). This declines the requestedTriState::Yes => true. A maintainer must confirm it..text.bunx,bun exec, compiled executables and the global file under run, test and build still needDO_NOT_TRACK=1.Notes
This PR was reworked. It first set
TriState::Yes => true(bunfig wins overDO_NOT_TRACK). A review objected:bunfig.tomlis a project file, so a cloned repository could turn uploads back on over a user'sDO_NOT_TRACK=1. The request allowed the other order if the docs state it. The PR now keeps that order, states it in the docs, and fixes a second report:bun testignorestelemetry = false.The rule. Uploads are off when any of these holds: a

telemetry = trueis inert.Yes => !DO_NOT_TRACKcame from Robustness pass across install, css, ffi, crypto, spawn, shell, and node compat #36165 and ships since v1.4.0.bun runandbun <file>. feat: switch disableTelemetry to bunfig #5690 put the key in the run block in 2023. On Native OpenTelemetry tracing (Bun.otel) #39965 a reply says "Kept the old scope in b922d31: the booleantelemetry = …arm is skipped forbun test; only the[telemetry]table applies there." (Native OpenTelemetry tracing (Bun.otel) #39965 (comment)). That PR then had its OpenTelemetry settings in a[telemetry]table; its head uses[otel]. Was the reply scope hygiene for that PR, or a decision about the key?telemetrythat is not a boolean. This PR adds no type error: onlybun <file>andbun runcheck the type, as on main. Everywhere the value counts as an opt-out. GitHub code search finds publicbunfig.tomlfiles with a[telemetry]table (5 of 541 sampled, for exampleenabled = false). A type error for every command would take theirbun install,bun testandbun buildfrom exit 0 to 1.What the setting does not reach (same on main; the docs now list these)
