2020-04-07CURLOPT_WRITEFUNCTION.3: add inline example and new see-alsoDaniel Stenberg
Closes #5192
2020-04-06cleanup: correct copyright year range on a few filesDaniel Stenberg
2020-04-05CURLINFO_CONDITION_UNMET: return true for 304 http status codeKwon-Young Choi
In libcurl, CURLINFO_CONDITION_UNMET is used to avoid writing to the output file if the server did not transfered a file based on time condition. In the same manner, getting a 304 HTTP response back from the server, for example after passing a custom If-Match-* header, also fulfill this condition. Fixes #5181 Closes #5183
2020-03-29curl.h: remnove CURL_VERSION_ESNI. Never supported nor documentedDaniel Stenberg
Considered experimental and therefore we can do this. Closes #5157
2020-03-27version: add 'cainfo' and 'capath' to version info structDaniel Stenberg

2020-03-24copyright: fix out-of-date copyright ranges and missing headersDaniel Stenberg
Reported by the new script 'scripts/copyright.pl'. The script has a regex whitelist for the files that don't need copyright headers. Removed three (mostly usesless) README files from docs/ Closes #5141
2020-03-18schannel: add "best effort" revocation check optionJohannes Schindelin
- Implement new option CURLSSLOPT_REVOKE_BEST_EFFORT and --ssl-revoke-best-effort to allow a "best effort" revocation check. A best effort revocation check ignores errors that the revocation check was unable to take place. The reasoning is described in detail below and discussed further in the PR. --- When running e.g. with Fiddler, the schannel backend fails with an unhelpful error message: Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate. Sadly, many enterprise users who are stuck behind MITM proxies suffer the very same problem. This has been discussed in plenty of issues: https://github.com/curl/curl/issues/3727, https://github.com/curl/curl/issues/264, for example. In the latter, a Microsoft Edge developer even made the case that the common behavior is to ignore issues when a certificate has no recorded distribution point for revocation lists, or when the server is offline. This is also known as "best effort" strategy and addresses the Fiddler issue. Unfortunately, this strategy was not chosen as the default for schannel (and is therefore a backend-specific behavior: OpenSSL seems to happily ignore the offline servers and missing distribution points). To maintain backward-compatibility, we therefore add a new flag (`CURLSSLOPT_REVOKE_BEST_EFFORT`) and a new option (`--ssl-revoke-best-effort`) to select the new behavior. Due to the many related issues Git for Windows and GitHub Desktop, the plan is to make this behavior the default in these software packages. The test 2070 was added to verify this behavior, adapted from 310.

2020-03-18multi: Improve parameter check for curl_multi_remove_handleJay Satiro

2020-03-02curl_getenv.3: Fix the memory handling descriptionJay Satiro
- Tell the user to call curl_free() to free the pointer returned by curl_getenv(). Prior to this change the user was directed to call free(), but that would not work in cases where the library and application use separate C runtimes and therefore have separate heap memory management.

2020-02-09altsvc: keep a copy of the file name to survive handle resetDaniel Stenberg
The alt-svc cache survives a call to curl_easy_reset fine, but the file name to use for saving the cache was cleared. Now the alt-svc cache has a copy of the file name to survive handle resets. Added test 1908 to verify. Reported-by: Craig Andrews Fixes #4898 Closes #4902

2020-01-26global_init: assume the EINTR bit by defaultDaniel Stenberg
- Removed from global_init since it isn't thread-safe. The symbol will still remain to not break compiles, it just won't have any effect going forward. - make the internals NOT loop on EINTR (the opposite from previously). It only risks returning from the select/poll/wait functions early, and that should be risk-free. Closes #4840

2019-12-26CURLOPT_HEADERFUNCTION.3: Document that size is always 1Jay Satiro
For compatibility with `fwrite`, the `CURLOPT_HEADERFUNCTION` callback is passed two `size_t` parameters which, when multiplied, designate the number of bytes of data passed in. In practice, CURL always sets the first parameter (`size`) to 1. This practice is also enshrined in documentation and cannot be changed in future. The documentation states that the default callback is `fwrite`, which means `fwrite` must be a suitable function for this purpose. However, the documentation also states that the callback must return the number of *bytes* it successfully handled, whereas ISO C `fwrite` returns the number of items (each of size `size`) which it wrote. The only way these numbers can be equal is if `size` is 1. Since `size` is 1 and can never be changed in future anyway, document that fact explicitly and let users rely on it.
