Nix's SDK model names its sidecar metadata field `narinfo` (matching the real .narinfo filename), not `narinfo_file`, so it fell through as a plain string: the CLI forwarded the raw local path straight into the package-create payload, and the API rejected it with a 422 ("Narinfo Field: Could not find specified package file") since it expected an upload identifier. Add a small allowlist of non-_file-suffixed fields that still carry a single uploadable file (currently just narinfo) and route them through the same validate/upload path as package_file. --narinfo is now typed as a real path (client-side existence check) and correctly gets uploaded first. Also adds a bug report (NIX_SCAN_BUG_REPORT.md) for a separate, non-CLI issue found while testing this against a live sandbox: nix packages consistently fail sync at a "Scanning Package" stage server-side with no reason given, regardless of this fix.

+ +## Notable inconsistency (possible root cause lead) + +`is_security_scannable: false` on both packages, yet the sync pipeline still +enters (and fails at) a "Scanning Package" stage, while +`security_scan_status` stays at its initial `"Awaiting Security Scan"` and +never progresses. This looks like a **generic malware/content-scan stage +that runs unconditionally for every format**, separate from the +format-gated vulnerability scanner. If that generic scan stage doesn't have +a handler for `.nar.xz` / `.narinfo` content yet, it would plausibly error +out immediately rather than skip — which matches the fast, deterministic +`Failed` we observed (~10–15s, well before any real scan could run) and the +complete absence of a `status_reason`. + +Also notable: on the package pushed with `--narinfo`, the primary `.nar.xz` +file reaches `is_synchronised: true`, but the `.narinfo` sidecar file stays +at `is_synchronised: false` — the package fails before ever finishing that +second file, regardless of it having uploaded correctly (checksums for both +files are present and correct in the response). + +## Why this isn't a CLI bug + +While investigating this, a real CLI bug was found and fixed separately +(`cloudsmith-cli` did not upload the `--narinfo` file via the file-upload +API before sending it to package-create, causing a 422 — fixed in +[#365](https://github.com/cloudsmith-io/cloudsmith-cli/pull/365)). After +that fix, `--narinfo` uploads correctly (see `is_synchronised: true` for the +primary file and a checksummed, attached `.narinfo` entry above) — but the +package still fails identically, **and pushing without `--narinfo` at all +fails the exact same way**. That rules the CLI out as the cause of the +scanning failure: the CLI is uploading files correctly and faithfully +surfacing every field the status API returns; there is no additional detail +being dropped client-side. + +## Impact + +- `nix` package support cannot ship — no package can reach a synchronised, + downloadable state on this environment. +- No self-serve diagnosis is possible from the CLI/API side: `status_reason` + is `null`, so whoever owns the scanning pipeline will need to check + service-side logs for these package/repo identifiers around the given + timestamps. + +## Suggested next steps + +1. Check the package-scanning worker's logs for + `cloudsmith/test-nix-support` around `2026-08-19T13:33:47Z` (slug_perm + `685zgiIVJkip`) and `2026-08-19T13:36:10Z` (slug_perm `wSHjxbhNfjjs`) on + the `kharrison.cloudsmith.sh` sandbox. +2. Confirm whether the generic "Scanning Package" stage has a content + handler for the `nix` format yet, and whether `is_security_scannable: + false` for `nix` is intentional (if so, the generic scan stage should + presumably skip rather than fail for non-scannable formats). +3. Populate `status_reason` for this failure class regardless of the above + fix, so future format rollouts are debuggable without backend log + access. diff --git a/cloudsmith_cli/cli/commands/push.py b/cloudsmith_cli/cli/commands/push.py index 96059807..289073e0 100644 --- a/cloudsmith_cli/cli/commands/push.py +++ b/cloudsmith_cli/cli/commands/push.py @@ -81,6 +81,18 @@ #: PACKAGE_FILE carries it is a source-package upload, so its members can be #: derived without ``--dsc-file`` (GitHub issue #56).

The CLI could therefore only ever show the generic HTTP status phrase (e.g. "Bad Request") for a failed upload, no matter what the storage backend actually said - this is what made an expired S3 upload token on a nix test sandbox look like an unexplained failure until reproduced by hand. Extract the from the storage backend's XML error body via a small regex rather than a full XML parser, since this is response content from wherever upload_url points and a real parser would add an XXE/entity-expansion surface for no benefit over pulling out one text field. Also updates NIX_SCAN_BUG_REPORT.md with the actual root cause (an expired upload token, unrelated to nix or narinfo) now that it's been confirmed resolved end-to-end against a live sandbox.

After -that fix, `--narinfo` uploads correctly (see `is_synchronised: true` for the -primary file and a checksummed, attached `.narinfo` entry above) — but the -package still fails identically, **and pushing without `--narinfo` at all -fails the exact same way**. That rules the CLI out as the cause of the -scanning failure: the CLI is uploading files correctly and faithfully -surfacing every field the status API returns; there is no additional detail -being dropped client-side. - -## Impact - -- `nix` package support cannot ship — no package can reach a synchronised, - downloadable state on this environment. -- No self-serve diagnosis is possible from the CLI/API side: `status_reason` - is `null`, so whoever owns the scanning pipeline will need to check - service-side logs for these package/repo identifiers around the given - timestamps. - -## Suggested next steps - -1. Check the package-scanning worker's logs for - `cloudsmith/test-nix-support` around `2026-08-19T13:33:47Z` (slug_perm - `685zgiIVJkip`) and `2026-08-19T13:36:10Z` (slug_perm `wSHjxbhNfjjs`) on - the `kharrison.cloudsmith.sh` sandbox. -2. Confirm whether the generic "Scanning Package" stage has a content - handler for the `nix` format yet, and whether `is_security_scannable: - false` for `nix` is intentional (if so, the generic scan stage should - presumably skip rather than fail for non-scannable formats). -3. Populate `status_reason` for this failure class regardless of the above - fix, so future format rollouts are debuggable without backend log - access. diff --git a/cloudsmith_cli/core/api/files.py b/cloudsmith_cli/core/api/files.py index 6c40ba5f..bd294cb5 100644 --- a/cloudsmith_cli/core/api/files.py +++ b/cloudsmith_cli/core/api/files.py @@ -1,6 +1,7 @@ """API - Files endpoints.""" import os +import re import click import cloudsmith_api @@ -14,6 +15,30 @@ from .init import get_api_client CHUNK_SIZE = 1024 * 1024 * 100 +#: Pulls the text out of an S3 XML error body, e.g. +#: ExpiredTokenThe provided token has +#: expired.....

Adds NIX_NARINFO_CHECKSUM_SYNC_LOOP.md documenting a distinct, more serious bug found reproducing on staging and production (not the sandbox): nix packages loop indefinitely between sync stages rather than reaching a terminal state, because the .narinfo file's checksum is never computed server-side. Client-side timing, upload ordering, concurrency, and cross-repo content-addressable-storage collisions were all tested directly against the raw API and ruled out - a guaranteed-fresh synthetic nar/narinfo pair reproduces the exact same loop on staging with completely normal sequential timing, while identical stress tests (reversed order, concurrent uploads, racing package-create against the uploads) stay clean on the sandbox. This is an unconditional backend behavior difference between the sandbox and staging/production, not a race or a data collision.

Independent of the above: the "cycle back to `Queued` after transient + `Failed`" behavior and the total lack of `status_reason` deserve a fix + regardless of root cause — a stuck package should terminally fail with a + reason, not loop forever consuming resources. +3.

+ +## Notable inconsistency (possible root cause lead) + +`is_security_scannable: false` on both packages, yet the sync pipeline still +enters (and fails at) a "Scanning Package" stage, while +`security_scan_status` stays at its initial `"Awaiting Security Scan"` and +never progresses. This looks like a **generic malware/content-scan stage +that runs unconditionally for every format**, separate from the +format-gated vulnerability scanner. If that generic scan stage doesn't have +a handler for `.nar.xz` / `.narinfo` content yet, it would plausibly error +out immediately rather than skip — which matches the fast, deterministic +`Failed` we observed (~10–15s, well before any real scan could run) and the +complete absence of a `status_reason`. + +Also notable: on the package pushed with `--narinfo`, the primary `.nar.xz` +file reaches `is_synchronised: true`, but the `.narinfo` sidecar file stays +at `is_synchronised: false` — the package fails before ever finishing that +second file, regardless of it having uploaded correctly (checksums for both +files are present and correct in the response). + +## Why this isn't a CLI bug + +While investigating this, a real CLI bug was found and fixed separately +(`cloudsmith-cli` did not upload the `--narinfo` file via the file-upload +API before sending it to package-create, causing a 422 — fixed in +[#365](https://github.com/cloudsmith-io/cloudsmith-cli/pull/365)). After +that fix, `--narinfo` uploads correctly (see `is_synchronised: true` for the +primary file and a checksummed, attached `.narinfo` entry above) — but the +package still fails identically, **and pushing without `--narinfo` at all +fails the exact same way**. That rules the CLI out as the cause of the +scanning failure: the CLI is uploading files correctly and faithfully +surfacing every field the status API returns; there is no additional detail +being dropped client-side. + +## Impact + +- `nix` package support cannot ship — no package can reach a synchronised, + downloadable state on this environment. +- No self-serve diagnosis is possible from the CLI/API side: `status_reason` + is `null`, so whoever owns the scanning pipeline will need to check + service-side logs for these package/repo identifiers around the given + timestamps. + +## Suggested next steps (superseded — see Resolution above) + +These were written before the root cause was known; kept for context on +what was considered at the time. + +1. ~~Check the package-scanning worker's logs...~~ — not needed once the + expired token was identified as the actual cause. +2. ~~Confirm whether the generic "Scanning Package" stage has a content + handler for the `nix` format yet...~~ — `is_security_scannable: false` + for `nix` is confirmed intentional; it resolves cleanly to `"Security + Scanning Not Supported"` once uploads actually succeed. +3. Still worth doing, independent of this report: consider whether + `status_reason` should be populated for scan-stage failures in general, + so a future upload-layer issue (expired token or otherwise) is + diagnosable from `cloudsmith status` alone rather than requiring + backend log access.
