📝 Description

The Go SDL parser accepts a memory or storage size with no unit as a byte count: byteQuantity goes through parseWithSuffix, which falls through to strconv.ParseFloat when no suffix matches, and TestByteQuantity pins val: 1 as 1 byte. The input schema types size as a plain string, so size: "1073741824" is valid SDL that the CLI deploys. The TS parser's parseSizeString required at least one unit letter, so the same SDL threw Invalid size string: 1073741824 out of generateManifest instead of returning the manifest Go returns. This makes the unit optional so a bare number multiplies by 1.

🔧 Purpose of the Change

  • Bug fix

📌 Related Issues

✅ Checklist

  • I've updated relevant documentation (JSDoc on convertResourceString)
  • Code follows Akash Network's style guide
  • I've added/updated relevant unit tests
  • Dependencies have been properly updated (none changed)
  • I agree and adhered to the Contribution Guidelines

📎 Notes for Reviewers

  • The new parity fixture v2.0/byte-count-sizes is the simple fixture with 128Mi and 1Gi written as 134217728 and 1073741824. Its expected manifest.json and group-specs.json are copies of simple's, because those are the exact byte values. I could not run Go locally, so the Go half of make test-sdl-parity in CI is what shows Go produces the same output for the new input.
  • "" and unit-only strings such as "Gi" still throw, as they still error in Go.
  • A fractional bare value rounds up like every other size in this parser ("1.5" is 2n), while Go truncates. That difference already exists for suffixed fractions (0.3Gi is 322122548 here and 322122547 in Go) and is left alone here.
  • The numeric group is \d+\.?\d*|\.\d+ rather than [\d.]+, so . and 1.2.3 throw instead of parsing as 0 and 2 bytes once the unit is optional. .5Gi and 1. still parse, as they do through Go's ParseFloat. parseCpuResourceString keeps the old [\d.]+ group; it is untouched by this PR and would be a separate change.

Walkthrough

The size parser now accepts unitless numeric strings as byte counts and limits numeric input to a single decimal. Tests cover accepted and rejected values. SDL input and output fixtures include byte-sized resource values.

Changes

Unitless SDL byte sizes

Layer / File(s) Summary
Parse and cover bare byte counts
ts/src/sdl/sizes.ts, ts/src/sdl/sizes.spec.ts, testdata/sdl/.../byte-count-sizes/*
convertResourceString documentation identifies bare numbers as byte counts. parseSizeString accepts bare numbers and restricts values to a single decimal. Tests cover bare numbers, zero, fractional values, equivalent binary-suffixed sizes, and malformed inputs. The SDL input and output fixtures include byte-sized resources.

CI note: the two red checks on ec84999 are runner-side, not this diff.

  • test (SUB_TESTS=go TEST_RACE=1 make test): both attempts ran on akash-runner-1 and were killed with Terminated (exit 143) 30 to 50 s after "running tests in go", with no failing test named. coverage (akash-runner-5) and sdl-parity (GitHub-hosted) on the same run execute the Go suite, including the new parity fixture, and pass.
  • proto (buf lint proto/provider): both attempts ran on akash-runner-3 and got Failure: 403 Forbidden from the buf registry. There are no proto changes here, and the same 403 shows on main's head ace99a2.

One rerun of the failed jobs reproduced both, so I have left them for a later rerun or a look at those two runners.

The Go SDL parser treats a size with no unit as a number of bytes
(byteQuantity -> parseWithSuffix falls through to strconv.ParseFloat, pinned
by TestByteQuantity's `val: 1` case), and the input schema types `size` as a
plain string, so `size: "1073741824"` is valid SDL that the CLI deploys.
The TS parser required a unit letter and threw
`Invalid size string: 1073741824` out of generateManifest instead of
producing the same manifest as Go.

Make the unit optional in parseSizeString so a bare number multiplies by 1.
Add a v2.0/byte-count-sizes parity fixture that is the simple fixture with
128Mi and 1Gi written as 134217728 and 1073741824; its expected output is a
copy of simple's because those are the exact byte values.
With the unit optional, `[\d.]+` let "." parse as 0 bytes and "1.2.3" as
2 bytes; Go's strconv.ParseFloat rejects both. Restrict the numeric group
to one decimal (digits with at most one point, ".5" and "1." included),
which also stops "1.2.3Gi" from silently parsing as 1.2Gi.
