# In the 'info' attribute, we store whether this request is 'safe' to retry if
495
# we get a disconnect while reading the response. It can have the values:
496
# read This is purely a read request, so retrying it is perfectly ok.
497
# idem An idempotent write request. Something like 'put' where if you put
498
# the same bytes twice you end up with the same final bytes.
499
# semi This is a request that isn't strictly idempotent, but doesn't
500
# result in corruption if it is retried. This is for things like
501
# 'lock' and 'unlock'. If you call lock, it updates the disk
502
# structure. If you fail to read the response, you won't be able to
503
# use the lock, because you don't have the lock token. Calling lock
504
# again will fail, because the lock is already taken. However, we
505
# can't tell if the server received our request or not. If it didn't,
506
# then retrying the request is fine, as it will actually do what we
507
# want. If it did, we will interrupt the current operation, but we
508
# are no worse off than interrupting the current operation because of
510
# semivfs Similar to semi, but specific to a Virtual FileSystem request.
511
# stream This is a request that takes a stream that cannot be restarted if
512
# consumed. This request is 'safe' in that if we determine the
513
# connection is closed before we consume the stream, we can try
515
# mutate State is updated in a way that replaying that request results in a
516
# different state. For example 'append' writes more bytes to a given
517
# file. If append succeeds, it moves the file pointer.
