ch_sendraw seems to fail when sending large chunks of data to a job
started in non-blocking mode. Is this expected?
Steps to reproduce:
- Copy the following into a file, and source it from vim
let args = ['cat']
let opts = {
\ 'noblock': 1
\}
let job = job_start(args, opts)
let data = repeat('X', 65537)
call ch_sendraw(job, data)
call ch_close_in(job)
Expected behavior:
- Nothing much (i.e. no errors)
Actual bevarior:
- E630: channel_write_input(): write while not connected
If on the other hand, I initialized data with 65536 bytes instead of
65537, then no error would be thrown.
You are using "noblock", which means the write may happen a bit later,
but then you use ch_close_in(), closing the channel before all the
writes are done. If you put a sleep there it works.
Oh, I thought ch_close_in() would wait for any pending write to
complete, but I guess that _special mode_ on `:help channel-close-in`
did refer to non blocking channels in the end, didn't it?! My bad!
Then the next question is, how could I wait for any pending write
operation to complete before calling ch_close_in()? Should I include a
EOF in the last message, instead of calling ch_close_in()?
