grpctunnel-demo

This demos concurrency issues with https://github.com/jhump/grpctunnel

Steps:

• Build client & server binaries like so: make build
• Replace src_data.bin file with your test data. I use a binary file of about ~ 2GB
• Run network_server in terminal 1
• Run network_client in terminal 2
• To initiate data transfer, signal network_server with SIGHUP like so: pkill -SIGHUP network_server
• The transfered files will be saved as: dst_data_at_0.bin dst_data_at_1.bin ...

To reproduce:

• Initiate two file transfers by issuing SIGHUP to network_server twice

Expected:

• The network_client shouild create exact copies of src_data.bin like so: dst_data_at_0.bin dst_data_at_1.bin

Actual:

• A single complete copy is created. The second transfer stalls resulting in an incomplete transfer.
