The "[" command is defined to accept "=" as an is-equal test. Bash extends
this to accept "==" too, but normal /bin/sh does not. I think this command
was developed on a box where /bin/sh is bash, but on standard ubuntu boxes,
/bin/sh is a smaller+faster non-Bash shell, and this gave "[: 1: X:
unexpected operator" errors.

This fixes a test failure found against current Twisted trunk in
test_mutable.Filenode.test_retrieve_producer_mdmf (when it uses
PausingAndStoppingConsumer). There must be some sort of race: I could
make it fail against Twisted-11.0 if I just increased the 0.5s delay in
test_download.PausingAndStoppingConsumer to about 0.6s, and could make
Twisted-trunk pass by reducing it to about 0.3s .
I fixed the test (as opposed to the bug) by replacing the delay with a
simple reliable eventually(), and adding extra asserts to fail the test
if the consumer's write() method is called while the producer is
supposed to be paused
The bug itself was that mutable.retrieve.Retrieve wasn't checking the
"stopped" flag after resuming from a pause, and thus delivered one
segment to a consumer that wasn't expecting it. I split out
stopped-flag-checking to separate function, which is now called
immediately after _check_for_paused(). I also cleaned up some Deferred
usage and whitespace.
* fix tahoe.cfg control of default mutable type
* tolerate arbitrary case in [client]mutable.format value
* small docs improvements
* use get_mutable_type() as a format-is-mutable predicate
* tighten up error message
* fix CLI commands (put, mkdir) to send format=, not mutable-type=
* fix tests
* test_cli: fix tests that observe t=json output, don't ignore failures in
'tahoe put'
* fix handling of version= to make it easier to use the default
* interpret ?mutable=true&format=MDMF as MDMF, not SDMF
The filecaps used to be produced with hints for 'k' and segsize, but they
weren't actually used, and doing so had the potential to limit how we change
those filecaps in the future. Also the parsing code had some problems dealing
with other numbers of extensions. Removing the existing fields and making the
parser tolerate (and ignore) extra ones makes MDMF more future-proof.
