This changes the OpenWriterAt implementation to make client/fd handling atomic. This PR stabilizes the situation of bigger files and multi-threaded uploads. The root cause boils down to the old "fun" property of pclouds fileops API: sessions are bound to TCP connections. This forces us to use a http client with only a single connection underneath. With large files, we reuse the same connection for each chunk. If that connection interrupts (e.g. because we are talking through the internet), all chunks will fail. The probability for latter one increases with larger files. As the point of the whole multi-threaded feature was to speed-up large files in the first place, this change pulls the client creation (and hence connection handling) into each chunk. This should stabilize the situation, as each chunk (and retry) gets its own connection. |
