Ensure that Gunicorn won't try to use chunked transfer-encoding for responses
to a HEAD request, so that `Response.close` will not write a terminating
chunk. Responses to a HEAD request MUST NOT have a message-body.
The application is still responsible for ensuring no message body is actually
generated in response to a HEAD request.
is_fileobject usgae was removed due to the use of the `tell` method check.
This change remove this check wich allows us to completely test if
fileno() is usable. Also it handle most of the exceptions around created by
breaking changes across Python versions. Hopefully we are good now.
fix#1174
Some systems edisable like SELINUX disable some flags so ignore the possible
error while chowning a log file. The error will be raised later anyway.
fix#1171
sendfile option don't set any default for now which makes the validation fail
(and then tests) since no boolean is given. For now just return when the value
is not set.
on OSX socket.TCP_FASTOPEN is set but make the server enter in a loop while
trying to set the options which makes gunicorn unusable.
For now remove TCP_FASTOPEN option until we find a solution
The --no-sendfile option had a confusing entry in the usage message.
Even though sendfile is enabled by default, the --no-sendfile flag
showed a true value as the default, which could be interpreted to
mean that by default sendfile support is disabled.
This change makes the default "None", meaning sendfile is not
disabled, which is hopefully slightly more clear.
Close#1156
Since the updated RFC 7230 implys that new Headers Key and Value should be
sent as USASCII only don't try to test utf8 headers in examples.
We now only encode them to ascii. Gunicorn will fail if it's unable to encode
them letting the responsability to the application to correctly encode the
response. (we are just a gateway).
While i'm here simplify the code to not create an extra function only used at
one place.
NOTE: if anyone come to a better solution, i am happy to revisit it on the
next release.
fix#1151
