Socket.io 1.4 to 1.7.2 temporary fix for #2405: Server socket id doesn’t match client’s socket id

If you’re affected by the major change outlined by this reported issue here’s a temporary fix you may want to try to get things working again without having to change all of your own code:

find . -name "socket.io.js" -exec sed -i -e 's/socket\.id \= self\.engine\.id;/socket\.id \= socket\.nsp \+ "\#" \+ self\.engine\.id;/' {} \;
find . -name "socket.io.js" -exec sed -i -e 's/this\.nsps\[nsp\]\.id \= this\.engine\.id;/this\.nsps\[nsp\]\.id \= nsp \+ "\#" \+ this\.engine\.id;/' {} \;
find . -name "socket.io.js.map" -exec sed -i -e 's/socket\.id \= self\.engine\.id;/socket\.id \= socket\.nsp \+ "\#" \+ self\.engine\.id;/' {} \;
find . -name "socket.io.js.map" -exec sed -i -e 's/this\.nsps\[nsp\]\.id \= this\.engine\.id;/this\.nsps\[nsp\]\.id \= nsp \+ "\#" \+ this\.engine\.id;/' {} \;
find . -name "socket.io.slim.js.map" -exec sed -i -e 's/socket\.id \= self\.engine\.id;/socket\.id \= socket\.nsp \+ "\#" \+ self\.engine\.id;/' {} \;
find . -name "socket.io.slim.js.map" -exec sed -i -e 's/this\.nsps\[nsp\]\.id \= this\.engine\.id;/this\.nsps\[nsp\]\.id \= nsp \+ "\#" \+ this\.engine\.id;/' {} \;
find . -name "socket.io.min.js" -exec sed -i -e 's/n\.id\=o\.engine\.id/n\.id\=n\.nsp\+"\#"\+o\.engine\.id/' {} \;
find . -name "socket.io.min.js" -exec sed -i -e 's/this\.nsps\[t\]\.id\=this\.engine\.id/this\.nsps\[t\]\.id\=t\+"\#"\+this\.engine\.id/' {} \;
find . -name "socket.io.slim.min.js" -exec sed -i -e 's/n\.id\=o\.engine\.id/n\.id\=n\.nsp\+"\#"\+o\.engine\.id/' {} \;
find . -name "socket.io.slim.min.js" -exec sed -i -e 's/this\.nsps\[t\]\.id\=this\.engine\.id/this\.nsps\[t\]\.id\=t\+"\#"\+this\.engine\.id/' {} \;
find . -name "manager.js" -exec sed -i -e 's/socket\.id \= self\.engine\.id;/socket\.id \= socket\.nsp \+ "\#" \+ self\.engine\.id;/' {} \;

Running this as a bash script in the root folder of your projects that depend on socket.io-client will replace all instances in the socket.io-client code to use the naming convention prior to v1.4 (and thus maintain consistency across client and server): the namespace followed by # and then the engine id.

If you run the bash script and want to undo the above changes, you’ll have to reverse the sed regular expressions and rerun the script.
