* Makefile.m32: rename -winssl option to -schannel and tidy upViktor Szakats2021-11-251-22/+22
| | | | | | | | | | | | - accept `-schannel` as an alternative to `CFG` option `-winssl` (latter still accepted, but deprecated) - rename internal variable `WINSSL` to `SCHANNEL` - make the `CFG` option evaluation shorter, without repeating the option name Reviewed-by: Marcel Raad Reviewed-by: Daniel Stenberg Closes #8053

* Makefile.m32: fix to not require OpenSSL with -libssh2 or -rtmp optionsViktor Szakats2021-10-251-3/+8
| | | | | | | | | | | | | | | Previously, -libssh2/-rtmp options assumed that OpenSSL is also enabled (and then failed with an error when not finding expected OpenSSL headers), but this isn't necessarly true, e.g. when building both libssh2 and curl against Schannel. This patch makes sure to only enable the OpenSSL backend with -libssh2/-rtmp, when there was no SSL option explicitly selected. - Re-implement the logic as a single block of script. - Also fix an indentation while there. Assisted-by: Jay Satiro Closes #7895

* urlapi: add curl_url_strerror()i-ky2021-09-271-4/+4
| | | | | | | | | | Add curl_url_strerror() to convert CURLUcode into readable string and facilitate easier troubleshooting in programs using URL API. Extend CURLUcode with CURLU_LAST for iteration in unit tests. Update man pages with a mention of new function. Update example code and tests with new functionality where it fits. Closes #7605

* examples/ephiperfifo.c: simplify signal handlerDaniel Gustafsson2021-08-131-5/+3
| | | | | | | | | | | | | The signal handler registered for SIGINT is only handling SIGINT so there isn't much need for inspecting the signo. While there, rename the handler to be more specific. g_should_exit should really be of sig_atomic_t type, but relying on autoconf in the examples seems like a bad idea so keep that for now.

* examples/cookie_interface: avoid printfing time_t directlyCarlo Marcelo Arenas Belón2021-07-261-2/+2
| | | | | | | | | | | | | | | time_t representation is undefined and varies on bitsize and signedness, and as of C11 could be even non integer. instead of casting to unsigned long (which would truncate in systems with a 32bit long after 2106) use difftime to get the elapsed time as a double and print that (without decimals) instead. alternatively a cast to curl_off_t and its corresponding print formatting could have been used (at least in POSIX) but portability and curl agnostic code was prioritized. Closes #7490

* docs/examples: use curl_multi_poll() in multi examplesDaniel Stenberg2021-07-0715-974/+290
| | | | | | | | | | | | The API is soon two years old and deserves being shown as the primary way to drive multi code as it makes it much easier to write code. multi-poll: removed multi-legacy: add to show how we did multi API use before curl_multi_wait/poll. Closes #7352
* examples: safer and more proper read callback logicDaniel Stenberg2021-07-016-149/+139
| | | | | | | | | | | | | | | | | | | The same callback code is used in: imap-append.c smtp-authzid.c smtp-mail.c smtp-multi.c smtp-ssl.c smtp-tls.c It should not assume that it can copy full lines into the buffer as it will encourage sloppy coding practices. Instead use byte-wise logic and check/acknowledge the buffer size appropriately. Reported-by: Harry Sintonen Fixes #7330 Closes #7331

* metalink: removeDaniel Stenberg2021-06-071-19/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Warning: this will make existing curl command lines that use metalink to stop working. Reasons for removal: 1. We've found several security problems and issues involving the metalink support in curl. The issues are not detailed here. When working on those, it become apparent to the team that several of the problems are due to the system design, metalink library API and what the metalink RFC says. They are very hard to fix on the curl side only. 2. The metalink usage with curl was only very briefly documented and was not following the "normal" curl usage pattern in several ways, making it surprising and non-intuitive which could lead to further security issues. 3. The metalink library was last updated 6 years ago and wasn't so active the years before that either. An unmaintained library means there's a security problem waiting to happen. This is probably reason enough. 4. Metalink requires an XML parsing library, which is complex code (even the smaller alternatives) and to this day often gets security updates. 5. Metalink is not a widely used curl feature. In the 2020 curl user survey, only 1.4% of the responders said that they'd are using it. In 2021 that number was 1.2%. Searching the web also show very few traces of it being used, even with other tools. 6. The torrent format and associated technology clearly won for downloading large files from multiple sources in parallel. Cloes #7176
