Max retries exceeded

[sergitrilles]

Hi,

I'm using your JSCompressor API (https://jscompressor.treblereel.dev/compile) to compile JavaScript code. When I send a very small payload (e.g., "var a = 1;"), the API works as expected. However, when I try to compile a larger payload—approximately 1.74 MB in size (generated from concatenating Blockly source files)—the request fails with an SSL error.

The error I receive is:

HTTPSConnectionPool(host='jscompressor.treblereel.dev', port=443): Max retries exceeded with url: /compile (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:2406)')))
It appears that the connection is being terminated during the TLS negotiation when a large payload is sent. This leads me to wonder if there might be a limit on the payload size or if there are certain TLS settings on the server that could be causing this issue.

Could you please advise on the following?

Is there a maximum payload size that the API supports?
Are there any known issues or recommended settings when dealing with large payloads?
Would you consider increasing the limit or providing guidelines for handling large files?
Any assistance or guidance would be greatly appreciated.

Thank you for your work on this API!

Best regards,

@sergitrilles thank you for your report, let me take a look. In case you case a js I can use to repro, please share it with me

[treblereel]

yeap, there is a limit to 1048576 bytes, techinally, I can extend it, let me check vps storage size.

Thank you for the quick response and for confirming the 1 MB limit. I really appreciate that you're looking into extending it. Please let me know if you need any further testing or information from my side.

Thanks again for your support!

Thank you for looking into this. To reproduce the issue, you can use a large JavaScript payload similar to what our build process generates for blockly_compressed.js. For example, when we concatenate our core files, we get a file of about 1,739,386 bytes that triggers the SSLEOFError when sent to the API.

For a minimal repro, you could try using a generated string payload. For instance, the following snippet creates a payload of roughly 1.74 MB:

// This creates a string with 1,739,386 'A' characters.
var payload = new Array(1739387).join("A");

If you use this payload in a POST request to https://jscompressor.treblereel.dev/compile (with the appropriate JSON structure), it should reproduce the issue. I can also provide the full blockly_compressed.js file generated by our build process if needed.

Thanks again for your help!

@sergitrilles increased to 2097152 bytes, please take a look

Hi,

Thank you for increasing the payload limit to 2MB. I tested the API with my payload (approximately 1,739,386 bytes), which is below the new limit, but I'm still encountering the following error:

HTTPSConnectionPool(host='jscompressor.treblereel.dev', port=443): Max retries exceeded with url: /compile (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:2406)')))

It seems that the connection is still being terminated during the TLS handshake. Could you please take a look and advise on how to resolve this issue?

Thank you very much for your help!

Best regards,

Dear @treblereel,

With a payload of 980,230 bytes, it works. However, with a payload of 1,225,230 bytes, it doesn’t work. It seems the value hasn’t increased. Could you please check?

Best

@sergitrilles yeap, I'll fix it asap, Thank you for details.
