Question: Sanitize API consumer input - line break CRLF/LF conversion

[dunglas]

I don't understand what you're trying to do exactly. Changing line breaks in a JSON document?

[theofidry]

Windows –> NIX:

tr -d '\r' < windowsfile > nixfile // delete the carriage returns

Mac –> NIX:

tr '\r' '\n' < macfile > nixfile // translate carriage returns into newlines

NIX –> Mac:

tr '\n' '\r' < macfile > nixfile // translate newlines into carriage returns

If you want to do that in Git you can simply configure your git return line and do a git add -A. If you absolutely need to do that in PHP look for the carriage return character and replace it manually.

Can't really help much more as I have no idea of what your use case is...

I'm not talking about source files but HTTP entity body (in JSON, for example). This question is about sanitizing user (API consumer) input.

[teohhanhui]

Windows browsers are required by HTML spec to normalize line breaks as CRLF during form submission. Not exactly our use case here, but I hope you get my point... The API probably needs to normalize the line breaks.

You mean the value of a textarea encoded in a JSON document or something like that?

Yes.

@teohhanhui What could we do about this ?

[teohhanhui]

I'm not sure, to be honest. This is an open question to hear the experiences of others and how they deal with the problem.

As this don't get any feedback, i'm closing here. Maybe we could create a proposal on the core repository ?
