blobmsg_json: fix double format string to avoid truncation and data loss

2026-05-03T20:17:39Z

Using %lf (= %f) with the default precision of 6 fractional decimal digits requires up to 317 characters for negative values close to -DBL_MAX (1 sign + 309 integer digits + 1 decimal point + 6 fraction digits + NUL), but buf[] only holds 317 bytes, leaving no room for the NUL terminator — snprintf truncates the last digit silently. Additionally, 6 fractional digits do not give round-trip accuracy for IEEE 754 doubles; 17 significant digits (%.17g) are required. Switch to %.17g which uses scientific notation for very large or small values, keeping the output well within the buffer, and guarantees round-trip accuracy for all finite doubles. Update the cram fixtures test_blobmsg.t and test_blobmsg_types.t to match the new output. The previous fixtures encoded the buggy behaviour: DBL_MIN serialised as "0.000000" and was silently flattened to zero on the JSON round-trip, while DBL_MAX produced a 309-digit decimal string.

libubox: Add ability to find ordinal position inside a table

2025-12-08T13:59:11Z

When adding anonymous objects to an array, the only way to select those objects (as in "json_select", i.e. moving the cursor) is to select them via their ordinality. This function returns a selectable index to those objects. Signed-off-by: Philip Prindeville Link: https://github.com/openwrt/libubox/pull/33 Signed-off-by: Álvaro Fernández Rojas

tests: shunit2: add test for _jshn_append via JSON script

Add another test which verifies _jshn_append leading space fix in commit 82cb5fd66af9 ("libubox: Drop extraneous space when appending values to variable") by appending keys to JSON objects, making sure there is no leading space on the first key when adding second key. test_jshn_append_via_json_script ASSERT:expected: but was:< first> ASSERT:expected: but was:< first second> Tests: #16 Signed-off-by: Petr Štetiar Link: https://github.com/openwrt/libubox/pull/30 Signed-off-by: Álvaro Fernández Rojas

tests: add blob-buffer overflow test

2021-04-29T13:34:21Z

The blob buffer has no limitation in place to prevent buflen to exceed maximum size. This commit adds a test to demonstrate how a blob increases past the maximum allowd size of 16MB. It continuously adds chunks of 64KB and with the 255th one blob_add() returns a valid attribute pointer but the blob's buflen does not increase. The test is used to demonstrate the failure, which is fixed with a follow-up commit. Signed-off-by: Zefir Kurtisi [adjusted test case for cram usage] Signed-off-by: Petr Štetiar

Seems like latest version of llvm compiler/sanitizer has changed behaviour during crash so `Aborted (core dumped)` is now printed to stdout.
