Checkes if the concurrent cache read/write works when the write is interrupted because of max-entry-size limits.
|
|
This is enhancement of 29a test, this test checks that cocurrency is resumed when the first channel is interrupted
|
|
in the middle of reading and the second channel already consumed some content from the cache entry.
|
|
This test is using a resumable response.
|
|
- with a profile, set max-entry-size to 1 (=1024 bytes)
|
|
- first channel makes a request for a resumable response
|
|
- second channel makes a request for the same resource, concurrent read happens
|
|
- first channel sets predicted data size on the entry with every chunk, it's doomed on 1024
|
|
- second channel now must engage interrupted concurrent write algorithm and read the rest of the content from the network
|
|
- both channels must deliver full content w/o errors
