Make build friendly to in-source builds.

v0.4.20

enabled in-source builds. (#172)

Improved integration tests

CI wasn't running elasticurl tests. (#171)

Also suppress output unless test fails

Client bootstrap API changes

Adapt to API changes in aws-c-io v0.4.20

Fix shared lib builds

v0.4.17

Added missing dll exports. (#167)

Fix linker error with most recent aws-c-common

aws_byte_buf_append_and_update is now implemented in common, so don't redefine it.

request with headers

Don't fire on_body for empty chunks of data. (#163)

This was leading to the python crt passing None to the on_body callback instead of byte buffer. Seems simpler to nip this complexity at the source.

aws_http_headers

Improved API for accessing headers.

Memory tracing updates

v0.4.13

Fixed tests to match tracer API updates (#160)

Memory tracing updates

Reworked fuzzer to use mem tracer (#159)

* Rewrote fuzzer to use mem tracer

Respect Content-Length

Content-Length is the boss (#158)

* Content-Length is the boss
- Don't freak out if body stream is set when Content-Length is 0.
  - aws-crt-java unit tests were doing this.
- Obey Content-Length when sending body, rather than trusting end-of-stream.
