http: support CURLOPT_PROTOCOLS_STR

2023-02-06T08:27:09Z

The CURLOPT_PROTOCOLS (and matching CURLOPT_REDIR_PROTOCOLS) flag was deprecated in curl 7.85.0, and using it generate compiler warnings as of curl 7.87.0. The path forward is to use CURLOPT_PROTOCOLS_STR, but we can't just do so unilaterally, as it was only introduced less than a year ago in 7.85.0. Until that version becomes ubiquitous, we have to either disable the deprecation warning or conditionally use the "STR" variant on newer versions of libcurl. This patch switches to the new variant, which is nice for two reasons: - we don't have to worry that silencing curl's deprecation warnings might cause us to miss other more useful ones - we'd eventually want to move to the new variant anyway, so this gets us set up (albeit with some extra ugly boilerplate for the conditional) There are a lot of ways to split up the two cases. One way would be to abstract the storage type (strbuf versus a long), how to append (strbuf_addstr vs bitwise OR), how to initialize, which CURLOPT to use, and so on. But the resulting code looks pretty magical: GIT_CURL_PROTOCOL_TYPE allowed = GIT_CURL_PROTOCOL_TYPE_INIT; if (...http is allowed...) GIT_CURL_PROTOCOL_APPEND(&allowed, "http", CURLOPT_HTTP); and you end up with more "#define GIT_CURL_PROTOCOL_TYPE" macros than actual code. On the other end of the spectrum, we could just implement two separate functions, one that handles a string list and one that handles bits. But then we end up repeating our list of protocols (http, https, ftp, ftp). This patch takes the middle ground. The run-time code is always there to handle both types, and we just choose which one to feed to curl. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano Signed-off-by: Johannes Schindelin

http: prefer CURLOPT_SEEKFUNCTION to CURLOPT_IOCTLFUNCTION

2023-02-06T08:27:09Z

The IOCTLFUNCTION option has been deprecated, and generates a compiler warning in recent versions of curl. We can switch to using SEEKFUNCTION instead. It was added in 2008 via curl 7.18.0; our INSTALL file already indicates we require at least curl 7.19.4. But there's one catch: curl says we should use CURL_SEEKFUNC_{OK,FAIL}, and those didn't arrive until 7.19.5. One workaround would be to use a bare 0/1 here (or define our own macros). But let's just bump the minimum required version to 7.19.5. That version is only a minor version bump from our existing requirement, and is only a 2 month time bump for versions that are almost 13 years old. So it's not likely that anybody cares about the distinction. Switching means we have to rewrite the ioctl functions into seek functions. In some ways they are simpler (seeking is the only operation), but in some ways more complex (the ioctl allowed only a full rewind, but now we can seek to arbitrary offsets). Curl will only ever use SEEK_SET (per their documentation), so I didn't bother implementing anything else, since it would naturally be completely untested. This seems unlikely to change, but I added an assertion just in case. Likewise, I doubt curl will ever try to seek outside of the buffer sizes we've told it, but I erred on the defensive side here, rather than do an out-of-bounds read.

http-push: prefer CURLOPT_UPLOAD to CURLOPT_PUT

The two options do exactly the same thing, but the latter has been deprecated and in recent versions of curl may produce a compiler warning. Since the UPLOAD form is available everywhere (it was introduced in the year 2000 by curl 7.1), we can just switch to it.
