Amaury Denoyelle cd22200d23 MEDIUM: mux-quic: release Tx buf on too small room ... This commit is a direct follow-up on the major rearchitecture of send buffering. It allows application protocol to react if current QCS sending buffer space is too small. In this case, the buffer can be released to the quic-conn layer. This allows to allocate a new QCS buffer and retry HTX parsing, unless connection buffer pool is already depleted. A new function qcc_release_stream_txbuf() serves as API for app protocol to release the QCS sending buffer. This operation fails if there is unsent data in it. In this case, MUX has to keep it to finalize transfer of unsent data to quic-conn layer. QCS is thus flagged with QC_SF_BLK_MROOM to interrupt snd_buf operation. When all data are sent to the quic-conn layer, QC_SF_BLK_MROOM is cleared via qcc_streams_sent_done() and stream layer is woken up to restart snd_buf. Note that a new function qcc_stream_can_send() has been defined. It allows app proto to check if sending is currently blocked for the current QCS. For now, it checks QC_SF_BLK_MROOM flag. However, it will be extended to other conditions with the following patches.		2024-01-31 16:28:54 +01:00
