cURL and libcurl, Open Source

curl the next few years

Roadmap of things Daniel Stenberg and Steve Holme want to work on next. It is intended to serve as a guideline for others for information, feedback and possible participation.

If you agree, disagree or would like to add stuff you want to work on, please join us on the curl-library list! This “roadmap” is likely to change over time. We’ll keep the updated ROADMAP in git.

New stuff – libcurl

  1. http2 test suite

  2. http2 multiplexing/pipelining

  3. SPDY

  4. SRV records

  5. HTTPS to proxy

  6. make sure there’s an easy handle passed in to curl_formadd(), curl_formget() and curl_formfree() by adding replacement functions and deprecating the old ones to allow custom mallocs and more

  7. HTTP Digest authentication via Windows SSPI

  8. GSSAPI authentication in the email protocols

  9. add support for third-party SASL libraries such as Cyrus SASL – may need to move existing native and SSPI based authentication into vsasl folder after reworking HTTP and SASL code

  10. SASL authentication in LDAP

  11. Simplify the SMTP email interface so that programmers don’t have to construct the body of an email that contains all the headers, alternative content, images and attachments – maintain raw interface so that programmers that want to do this can

  12. Allow the email protocols to return the capabilities before authenticating. This will allow an application to decide on the best authentication mechanism

  13. Allow Windows threading model to be replaced by Win32 pthreads port

  14. Implement a dynamic buffer size to allow SFTP to use much larger buffers and possibly allow the size to be customizable by applications. Use less memory when handles are not in use?

New stuff – curl

  1. Embed a language interpreter (lua?). For that middle ground where curl isn’t enough and a libcurl binding feels “too much”. Build-time conditional of course.

  2. Simplify the SMTP command line so that the headers and multi-part content don’t have to be constructed before calling curl

Improve

  1. build for windows (considered hard by many users)

  2. curl -h output (considered overwhelming to users)

  3. we have  > 160 command line options, is there a way to redo things to simplify or improve the situation as we are likely to keep adding features/options in the future too

  4. docs (considered “bad” by users but how do we make it better?)

  5. authentication framework (consider merging HTTP and SASL authentication to give one API for protocols to call)

  6. Perform some of the clean up from the TODO document, removing old definitions and such like that are currently earmarked to be removed years ago

Remove

  1. cmake support (nobody maintains it)

  2. makefile.vc files as there is no point in maintaining two sets of Windows makefiles. Note: These are currently being used by the Windows autobuilds
