Edward Thomson 3f54ba8b 2020-01-18T13:51:40 credential: change git_cred to git_credential We avoid abbreviations where possible; rename git_cred to git_credential. In addition, we have standardized on a trailing `_t` for enum types, instead of using "type" in the name. So `git_credtype_t` has become `git_credential_t` and its members have become `GIT_CREDENTIAL` instead of `GIT_CREDTYPE`. Finally, the source and header files have been renamed to `credential` instead of `cred`. Keep previous name and values as deprecated, and include the new header files from the previous ones.

Edward Thomson e9cef7c4 2020-01-11T23:53:45 http: introduce GIT_ERROR_HTTP Disambiguate between general network problems and HTTP problems in error codes.
Edward Thomson 7372573b 2019-10-25T12:22:10 httpclient: support expect/continue Allow users to opt-in to expect/continue handling when sending a POST and we're authenticated with a "connection-based" authentication mechanism like NTLM or Negotiate. If the response is a 100, return to the caller (to allow them to post their body). If the response is *not* a 100, buffer the response for the caller. HTTP expect/continue is generally safe, but some legacy servers have not implemented it correctly. Require it to be opt-in.

Edward Thomson 6b208836 2019-12-18T21:55:28 httpclient: handle chunked responses Detect responses that are sent with Transfer-Encoding: chunked, and record that information so that we can consume the entire message body.
Edward Thomson 6a095679 2019-12-14T10:34:36 httpclient: support authentication Store the last-seen credential challenges (eg, all the 'WWW-Authenticate' headers in a response message). Given some credentials, find the best (first) challenge whose mechanism supports these credentials. (eg, 'Basic' supports username/password credentials, 'Negotiate' supports default credentials). Set up an authentication context for this mechanism and these credentials. Continue exchanging challenge/responses until we're authenticated.
Edward Thomson 1152f361 2019-12-13T18:37:19 httpclient: consume final chunk message When sending a new request, ensure that we got the entirety of the response body. Our caller may have decided that they were done reading. If we were not at the end of the message, this means that we need to tear down the connection and cannot do keep-alive. However, if the caller read all of the message, but we still have a final end-of-response chunk signifier (ie, "0\r\n\r\n") on the socket, then we should consider that the response was successfully copmleted. If we're asked to send a new request, try to read from the socket, just to clear out that end-of-chunk message, marking ourselves as disconnected on any errors.
Edward Thomson 84b99a95 2019-12-12T13:53:43 httpclient: add chunk support to POST Teach httpclient how to support chunking when POSTing request bodies.
Edward Thomson eacecebd 2019-12-12T13:25:32 httpclient: introduce a simple http implementation Introduce a new http client implementation that can GET and POST to remote URLs. Consumers can use `git_http_client_init` to create a new client, `git_http_client_send_request` to send a request to the remote server and `git_http_client_read_response` to read the response. The http client implementation will perform the I/O with the remote server (http or https) but does not understand the git smart transfer protocol. This allows us to split the concerns of the http subtransport from the actual http implementation.
