Just redirect the logs to /dev/null

Hello, will you modify the dockerfile to achieve this ?

Originally posted by @dameert in #2 (comment)

Or could you remove line 50 in the server.js file ?
That line is logging GDPR sensitive information. The error logs are still usefull to us.

Disabling logs

The tool is logging its results to the console.
If a qr code would contain personal data, this might breach GDRP guidelines in certain contexts.

Would you be able to add an Environment Variable to the docker image that disables logging.

(optionally with different levels: no logs, error logs, all logs)

Internal server error with PDF

Hello,

I tested the following use case (imagine EUDCC):

• I have paper version of a qrcode that I want to pass to the docker image
• I used a scanner to generate a PDF with the qrcode (9MB file at 600dpi)
• The process uses 100% cpu, and around 21MB memory
• I receive an internal server error

Docker logs gives me the following
Error: child exited with code 4 at ChildProcess.<anonymous> (/usr/src/app/node_modules/await-spawn/index.js:28:21) at ChildProcess.emit (node:events:390:28) at maybeClose (node:internal/child_process:1064:16) at Process.ChildProcess._handle.onexit (node:internal/child_process:301:5) { code: 4, stderr: BufferListStream { _bufs: [], length: 0, _readableState: ReadableState { objectMode: false, highWaterMark: 16384, buffer: BufferList { head: null, tail: null, length: 0 }, length: 0, pipes: null, pipesCount: 0, flowing: null, ended: false, endEmitted: false, reading: false, sync: true, needReadable: false, emittedReadable: false, readableListening: false, resumeScheduled: false, paused: true, emitClose: true, autoDestroy: false, destroyed: false, defaultEncoding: 'utf8', awaitDrain: 0, readingMore: false, decoder: null, encoding: null }, readable: true, _events: [Object: null prototype] {}, _eventsCount: 0, _maxListeners: undefined, _writableState: WritableState { objectMode: false, highWaterMark: 16384, finalCalled: false, needDrain: false, ending: false, ended: false, finished: false, destroyed: false, decodeStrings: true, defaultEncoding: 'utf8', length: 0, writing: false, corked: 0, sync: true, bufferProcessing: false, onwrite: [Function (anonymous)], writecb: null, writelen: 0, bufferedRequest: null, lastBufferedRequest: null, pendingcb: 0, prefinished: false, errorEmitted: false, emitClose: true, autoDestroy: false, bufferedRequestCount: 0, corkedRequestsFree: [CorkedRequest] }, writable: true, allowHalfOpen: true, [Symbol(kCapture)]: false }, stdout: BufferListStream { _bufs: [], length: 0, _readableState: ReadableState { objectMode: false, highWaterMark: 16384, buffer: BufferList { head: null, tail: null, length: 0 }, length: 0, pipes: null, pipesCount: 0, flowing: null, ended: false, endEmitted: false, reading: false, sync: true, needReadable: false, emittedReadable: false, readableListening: false, resumeScheduled: false, paused: true, emitClose: true, autoDestroy: false, destroyed: false, defaultEncoding: 'utf8', awaitDrain: 0, readingMore: false, decoder: null, encoding: null }, readable: true, _events: [Object: null prototype] {}, _eventsCount: 0, _maxListeners: undefined, _writableState: WritableState { objectMode: false, highWaterMark: 16384, finalCalled: false, needDrain: false, ending: false, ended: false, finished: false, destroyed: false, decodeStrings: true, defaultEncoding: 'utf8', length: 0, writing: false, corked: 0, sync: true, bufferProcessing: false, onwrite: [Function (anonymous)], writecb: null, writelen: 0, bufferedRequest: null, lastBufferedRequest: null, pendingcb: 0, prefinished: false, errorEmitted: false, emitClose: true, autoDestroy: false, bufferedRequestCount: 0, corkedRequestsFree: [CorkedRequest] }, writable: true, allowHalfOpen: true, [Symbol(kCapture)]: false } }

I noticed that zbarimg rasterizes the pdf file automatically and might corrupt the qrcode in the pdf file?
