NS_E_CURL_NOTSAFE
NS_E_CURL_NOTSAFE in a format, graph or streaming trace
for it (0xC00D1324) the decisive boundary is the requested URL operation is rejected by the URL safety rules before navigation or file access. Diagnose the notsafe URL check directly and avoid inferring the cause only from the visible playback symptom.
Before any socket is opened, the player decomposes a URL into scheme, authority, host, port, path and escaped data at the notsafe checkpoint. It may also combine a relative reference with a base URL or convert a file URL into a path; each operation has a different validity rule while tracing the notsafe path. In the case of this result, preserve the earliest lower-level result because wrappers can map several different causes to the same HRESULT during a controlled notsafe retest.
Nearby results are not interchangeable
Main distinction: URL syntax errors occur before server DNS, proxy selection or streaming-session creation for evidence about notsafe.
| Nearby HRESULT | How to compare it |
|---|---|
NS_E_CURL_INVALIDCHAR | Compare the owning API and first rejected value; it belongs to a neighboring checkpoint, not automatically to the same cause as this result. |
NS_E_CURL_INVALIDHOSTNAME | Use object state and operation order to decide which code is authoritative when both appear in one trace in the notsafe diagnostic record. |
NS_E_CURL_INVALIDPATH | Retain this result separately if it appears only after the condition has cleared. |
Failure anatomy
The notsafe url check is reached when the requested URL operation is rejected by the URL safety rules before navigation or file access. The caller must not assume that the next filter, packet, session or metadata state exists after this result.
Use run a parse-only operation first, then compare the safety policy for the same normalized URL without navigating to it as the negative control during a controlled notsafe retest. A later HRESULT means this checkpoint was cleared and the new result belongs to a different stage for evidence about notsafe.
One-component URL experiment
- Log
0xC00D1324, it, the exact operation and the first failure time before closing the notsafe incident. - Preserve the original unmodified string, character count, encoding, base URL if any, parsed scheme, host, port and path, plus required and supplied output-buffer lengths in the notsafe diagnostic record.
- Do not reuse a graph, session, reader or metadata object created before the relevant configuration or resource changed when isolating the notsafe case.
- Perform one isolated test: run a parse-only operation first, then compare the safety policy for the same normalized URL without navigating to it at the notsafe checkpoint.
- Repeat through the same API and protocol path; a different player or local-copy test is useful only as a comparison, not as proof that the notsafe URL check is fixed.
- Confirm the expected next state and retain any new HRESULT as a separate downstream result during a controlled notsafe retest.
Preserve the raw and parsed URL
| Capture | Why it matters |
|---|---|
| Owning call | Record the API method, object identity, thread or callback and timestamp for the notsafe URL check. |
| Decisive values | the original unmodified string, character count, encoding, base URL if any, parsed scheme, host, port and path, plus required and supplied output-buffer lengths before closing the notsafe incident. |
| Object generation | Note when the reader, writer, graph, URL object, streaming session or metadata provider was created; stale state can reproduce it after configuration has changed. |
| First nested result | Keep the earliest codec, COM, socket, DNS, parser or provider status before it; later UI messages are less specific. |
| Comparison case | Use one known-good resource that exercises the same the notsafe URL check while changing only the rejected precondition. |
What the parser result proves
| Retest result | Interpretation |
|---|---|
| The identical call still returns the code | The values governing the notsafe URL check are unchanged, or the caller is still using an older object generation. |
| A fresh object succeeds | Lifetime or cached state contributed to it; correct object recreation instead of applying a machine-wide workaround during a controlled notsafe retest. |
| The call advances to another HRESULT | the notsafe URL check boundary was cleared. Diagnose the new code at its own format, graph, URL, network or metadata stage before closing the notsafe incident. |
| Only one resource fails | The evidence favors content, URL, publishing point, stream, attribute or object-specific state rather than a global outage in the notsafe diagnostic record. |
Misleading actions
- blindly decoding and re-encoding the whole URL, which can change reserved delimiters and resource identity when isolating the notsafe case.
- Do not erase the first occurrence by repeatedly retrying; callbacks and reconnects can replace the useful state with a later wrapper error at the notsafe checkpoint.
- Do not publish credentials, protected-content material or complete private URLs while tracing the notsafe path. Record redacted identifiers, lengths, hashes and protocol fields needed to reproduce the notsafe URL check.

Treat it as resolved only when the same API path crosses this checkpoint; success through a different player or cached copy is merely supporting evidence for evidence about notsafe.
