5.2.1 - In handle_setheader(), setting a header to a non-empty whitespace string will now send a blank header. Using an empty string will still remove the header altogether (this has not changed). - Internally simplify handle_setheader() as a wrapper for handle_setopt(httpheader) - Fix an issue where curl_fetch_stream() might not return all bytes received by the C layer if the server closed the connection mid-response. - No longer enable CURLOPT_UNRESTRICTED_AUTH by default - Fix code to build with -DR_NO_REMAP (add all the Rf_ prefixes) 5.2.0 - The CURL_CA_BUNDLE envvar is now also used on non-Windows. - curl_echo() now uses a random available port to run httpuv - Add workaround for slowness in curl_echo() on Linux - Fix a few printf format warnings 5.1.0 - Windows: update to libcurl 8.3.0 + nghttp2 2-1.56 + openssl 3.1.2. 5.0.2 - Fix a unit test for behavioral change in libcurl 8.0.0 - Support seekfunction callback 5.0.1 - Setting verbose=TRUE now prints to R's stderr instead of the process, such that it works better with some GUIs. - multi_download() now sets mtime for downloaded files from server - form_file() now supports setting an alternate file name (#290) - Fix for multi_download() when downloading 0byte files - Use a self hosted httpbin test server 5.0.0 - New function multi_download() which supports concurrent downloads and resuming download for large files, while giving detailed progress information. - Windows: updated libcurl to 7.84.0 + nghttp2 - Windows: default to CURLSSLOPT_NATIVE_CA when using openssl unless an ennvar with CURL_CA_BUNDLE is set. - Use the new optiontype API for type checking if available (libcurl 7.73.0) 4.3.3 - Add support for setting ssl_ctx_function callbacks - Normalize curlopt_postfields to curlopt_copypostfields to transfer ownership of the input data to libcurl. - Fix strict-prototype errors 4.3.2 - Windows: update binaries to openssl 1.1.1k and libssh2 1.9.0 - Windows: fix build for experimental ucrt toolchains 4.3.1 - Make tests pass if 'httpuv' is not available (BDR) - Some cleanup for Windows compilers 4.3 - No longer enable HTTP/2 by default on libcurl < 7.62.0 because some old libcurl versions have annoying HTTP/2 bugs which randomly cause requests to fail. Note that libcurl 7.62 and up always enable HTTP/2 when possible, this doesn't change. - Add paragraph to intro vignette that explain ENUM options, which are a common source of bugs. Specifically explain CURLOPT_HTTP_VERSION. - curl::has_internet() now checks that result of nslookup is actually correct. This should detect offline networks with fake internal DNS. - curl::send_mail() now supports TLS connections, by specifying the smtps:// protocol in the smtp_server argument. The use_ssl argument actually controls whether STARTTLS is enabled; the function documentation has been updated to clarify that, and the default for use_ssl has been changed to "try" (=TRUE). - Fix build for gcc 10 (-fno-common) requested by CRAN. 4.2 - Fix for old versions of libcurl (build was broken in 4.1 on RHEL / CentOS). - Add hostname to timeout errors (#190) 4.1 - Fixed typechecking code for new internal macro names in libcurl 7.66 - Rewrite typechecking to work better with clang and old libcurl (#192) - has_internet() now checks for connectivity via a proxy server if one is detected - Windows: respect the CURL_SSL_BACKEND variable for people that want to use OpenSSL. - Windows: respect CURL_CA_BUNDLE if (and only if) CURL_SSL_BACKEND == openssl - curl_download now writes to a temporary file, which is renamed to the destfile upon success. This prevents corrupt files when a download fails or is interrupted. - Automatically set forbid_reuse = TRUE in curl_echo() handles - Update symbol table to 7.66.0 4.0 - Stricter type checking for handle options based on macros - curl_symbols is now a function instead of a static table to allow easy filtering - curl_fetch_memory now over-allocates also on unix to avoid many realloc calls - Re-enable cookie unit test which should be fixed in curl 7.64.0 - Fix encoding of paths for downloading and uploading files (@jennybc, #183) - Fix LTO declaration warning for R_get_proxy_for_url - Better support for setting slist (string vector) options such as mail_rcpt - New send_mail() function to send emails with the libcurl smtp client - Add function curl_upload() to upload file to FTP or SCP server - Windows: upgrade to libcurl 7.64.1 - Update symbol data to curl 7.64.1 3.3 - The 'data' callback from multi_add() gains a 'final' parameter - The 'data' callback from multi_add() can be given a file path to stream to files - New internal efficient file_writer type used when 'data' callback is a file path - Progress / Xfer callback functions are now explicitly protected (#157) - Tweak some unit tests to give less false positives - curl_echo() has been changed to return better structured output - Added curl_fetch_echo() as a wrapper for curl_echo() - Response for curl_fetch_memory() gains a 'type' field with the content-type - Fix a unit test for OpenSSL 1.1.1 - Better default progress function if no progresfun or xferinfofun is set - Skip unit tests if no internet is available - Fix rchk and valgrind warnings from CRAN - Updated symbol table up with curl 7.64.0 - Use native routine registration and visibility 3.2 - Windows: Update libcurl to 7.59.0 - Update curl_symbols dataset to 7.59.0 - Fix an IDN unit test (malmö.se has messed up their SSL cert) - Add unit test for multi_fdset - Add backport of trimws for R 3.1 3.1 - Fix potential memory bug in curl() when doubling the buffer is insufficient. - Windows: update to libcurl 7.56.1, restore support for libssh2. - Added unit test for curl_echo() to post large multipart data. - Fix IDN unit test error "string has forbidden bi-directional properties" 3.0 - MAJOR CHANGE ON WINDOWS: On Windows 7 / 2008-R2 and up we switch from OpenSSL to native Windows SSL (secure channel). Therefore curl now uses certificates from the windows certificate manager. This enables users on corporate/government networks to connect through enterprise proxies and such. On Windows Vista/2008 and older (including CRAN) we still use OpenSSL to guarantee TLS 1.1/1.2 support. Other changes: - Windows: updated libcurl to v7.56.0 with dual SSL and native IDN/SSPI - multi_add() and curl_fetch_multi() gain an optional 'data' callback parameter - New function multi_fdset() returns the file descriptors of a multi pool - Add CURLOPT_PROXYAUTH = CURLAUTH_ANY to default handle settings 2.8.1 - Windows: switch back to OpenSSL instead of SecureChannel because Windows 2008 (CRAN) does not support TLS 1.1 and TLS 1.2 which is required for many servers now. 2.8 (unpublished) - Windows: EXPERIMENTAL: on R 3.5+ curl now uses SecureChannel instead of OpenSSL for https. - Windows: updated libcurl to v7.54.1 with native windows IDN.
