Hi, There has been few discussions/patches/reviews on pulling in the bufferedhttp.py (currently in use in swift) to python-swiftclient and even to oslo, so that we can leverage features like buffering http headers and use of 'expect: 100-continue' etc which is currently not suported by the httplib library. Please take a look at the the patch sets that addresses this in swift <https://review.openstack.org/#/c/56558/8> and oslo<https://review.openstack.org/#/c/57605/> . A usecase <https://review.openstack.org/#/c/55517/> of this approach is in python-swiftclient where it makes use of the 100-continue headers to receive a fast fail during an upload without ending up uploading the entire chunk in case of auth failures. The intention behind this mail is to gain some traction around these patches which have been hanging around for quite some time now. -- Thanks And Regards Amala Basha +91-7760972008 -------------- next part -------------- An HTML attachment was scrubbed...
