| Summary | 0006610: MHD_send_on_connection_() with MHD_SSO_HDR_CORK on MHD_CONNECTION_FOOTERS_SENDING makes chunked transfer stuck | ||||
| Description | We have a https server application which use chunked encoding to transfer data from FreeBSD machine. After freebsd-ports libmicrohttpd updating from 0.9.58 to 0.9.70 wget(and curl) on client side (Ubuntu) getting stuck. As I saw in curl trace-ascii logs last CRLF in chunk ending is missing. But seems that it should be sent from MHD_connection_handle_write() on MHD_CONNECTION_FOOTERS_SENDING state. I tried to replace MHD_SSO_HDR_CORK on MHD_SSO_NO_CORK in MHD_send_on_connection_() call and rebuilt library - problem was solved. Could you check is it proper to send last chunk with enabled CORK? Transfers with disabled chunked encoding works well. | ||||

Here is modified chunked_example.zip from src/examples. It sends (using TLS) testfile.bin which could be generated by command: dd if=/dev/zero of=testfile.bin bs=1M count=1 Command to receive data: curl -v -k -o 1.bin "https://127.0.0.1:9080" --trace-ascii trace.log Issue was reproduced on ubuntu (20.04/18.04) machine. |

Fixed in Git master as suggested: you are correct, we must not cork when sending the footer. |

Fix committed to master branch. |
