2020-02-22tests: Added a unit test for SHA256 digest generationSteve Holme
Follow up to 2b5b37c. Closes #4968
2020-02-22md4: Fixed compilation issues when using GNU TLS gcryptSteve Holme
* Don't include 'struct' in the gcrypt MD4_CTX typedef * The call to gcry_md_read() should use a dereferenced ctx * The call to gcry_md_close() should use a dereferenced ctx Additional minor whitespace issue in the USE_WIN32_CRYPTO code. Closes #4959
2020-02-21http2: now require nghttp2 >= 1.12.0Daniel Stenberg
To simplify our code and since earlier versions lack important function calls libcurl needs to function correctly. nghttp2 1.12.0 was relased on June 26, 2016. Closes #4961

2020-02-21GnuTLS: Always send client certjethrogb
TLS servers may request a certificate from the client. This request includes a list of 0 or more acceptable issuer DNs. The client may use this list to determine which certificate to send. GnuTLS's default behavior is to not send a client certificate if there is no match. However, OpenSSL's default behavior is to send the configured certificate. The `GNUTLS_FORCE_CLIENT_CERT` flag mimics OpenSSL behavior. Authored-by: jethrogb on github Fixes #1411 Closes #4958

Spotted by 'codespell' Closes #4957
2020-02-20win32: USE_WIN32_CRYPTO to enable Win32 based MD4, MD5 and SHA256 functionsSteve Holme
Whilst lib\md4.c used this pre-processor, lib\md5.c and src\tool_metalink.c did not and simply relied on the WIN32 pre-processor directive. Reviewed-by: Marcel Raad Closes #4955
2020-02-19connect: remove some spurious infof() callsDaniel Stenberg
As they were added primarily for debugging, they provide little use for users. Closes #4951

2020-02-18tool_util: Improve Windows version of tvnow()Jay Satiro
- Change tool_util.c tvnow() for Windows to match more closely to timeval.c Curl_now(). - Create a win32 init function for the tool, since some initialization is required for the tvnow() changes. Prior to this change the monotonic time function used by curl in Windows was determined at build-time and not runtime. That was a problem because when curl was built targeted for compatibility with old versions of Windows (eg _WIN32_WINNT < 0x0600) it would use GetTickCount which wraps every 49.7 days that Windows has been running. This change makes curl behave similar to libcurl's tvnow function, which determines at runtime whether the OS is Vista+ and if so calls QueryPerformanceCounter instead. (Note QueryPerformanceCounter is used because it has higher resolution than the more obvious candidate GetTickCount64). The changes to tvnow are basically a copy and paste but the types in some cases are different. Ref: https://github.com/curl/curl/issues/3309 Closes https://github.com/curl/curl/pull/4847

2020-02-17cookies: make saving atomic with a renameDaniel Stenberg

Otherwise, a very fast single transfer ricks starving out other concurrent transfers. Closes #4927
2020-02-16ftp: convert 'sock_accepted' to a plain booleanDaniel Stenberg
This was an array indexed with sockindex but it was only ever used for the secondary socket. Closes #4929

2020-02-12tool_homedir: Change GetEnv() to use libcurl's curl_getenv()Jay Satiro
- Deduplicate GetEnv() code. - On Windows change ultimate call to use Windows API GetEnvironmentVariable() instead of C runtime getenv(). Prior to this change both libcurl and the tool had their own GetEnv which over time diverged. Now the tool's GetEnv is a wrapper around curl_getenv (libcurl API function which is itself a wrapper around libcurl's GetEnv). Furthermore this change fixes a bug in that Windows API GetEnvironmentVariable() is called instead of C runtime getenv() to get the environment variable since some changes aren't always visible to the latter.

2020-02-12strerror: Increase STRERROR_LEN 128 -> 256Jay Satiro
STRERROR_LEN is the constant used throughout the library to set the size of the buffer on the stack that the curl strerror functions write to. Prior to this change some extended length Windows error messages could be truncated. Closes https://github.com/curl/curl/pull/4920
2020-02-12multi: fix outdated commentJay Satiro
- Do not say that conn->data is "cleared" by multi_done(). If the connection is in use then multi_done assigns another easy handle still using the connection to conn->data, therefore in that case it is not cleared. Closes https://github.com/curl/curl/pull/4901
2020-02-12easy: remove dead codeJay Satiro
multi is already assigned to data->multi by curl_multi_add_handle. Closes https://github.com/curl/curl/pull/4900
2020-02-09smtp: Simplify the MAIL command and avoid a duplication of send stringsSteve Holme
This avoids the duplication of strings when the optional AUTH and SIZE parameters are required. It also assists with the modifications that are part of #4892. Closes #4903
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
2020-02-09url: Include the failure reason when curl_win32_idn_to_ascii() failsSteve Holme

2020-02-07digest: Do not quote algorithm in HTTP authorisationPierre-Yves Bigourdan
RFC 7616 section 3.4 (The Authorization Header Field) states that "For historical reasons, a sender MUST NOT generate the quoted string syntax for the following parameters: algorithm, qop, and nc". This removes the quoting for the algorithm parameter. Reviewed-by: Steve Holme Closes #4890

2020-02-07ftp: remove superfluous checking for crlf in user or pwdDaniel Stenberg
... as this is already done much earlier in the URL parser. Also add test case 894 that verifies that pop3 with an encodedd CR in the user name is rejected. Closes #4887

2020-02-05ftp: shrink temp buffers used for PORTDaniel Stenberg
These two stack based buffers only need to be 46 + 66 bytes instead of 256 + 1024. Closes #4880
2020-02-04altsvc: set h3 version at a common single spotDaniel Stenberg
... and move the #ifdefs out of the functions. Addresses the fact they were different before this change. Reported-by: Harry Sintonen Closes #4876
2020-02-04altsvc: improved header parserHarry Sintonen
- Fixed the flag parsing to apply to specific alternative entry only, as per RFC. The earlier code would also get totally confused by multiprotocol header, parsing flags from the wrong part of the header. - Fixed the parser terminating on unknown protocols, instead of skipping them. - Fixed a busyloop when protocol-id was present without an equal sign. Closes #4875

2020-01-28multi_done: if multiplexed, make conn->data point to another transferDaniel Stenberg
... since the current transfer is being killed. Setting to NULL is wrong, leaving it pointing to 'data' is wrong since that handle might be about to get freed. Fixes #4845 Closes #4858 Reported-by: dmitrmax on github

2020-01-28global_init: move the IPv6 works status bool to multi handleDaniel Stenberg
Previously it was stored in a global state which contributed to curl_global_init's thread unsafety. This boolean is now instead figured out in curl_multi_init() and stored in the multi handle. Less effective, but thread safe. Closes #4851

... and check for inconsistencies for OS400 at build time with the new chkstrings tool. Closes #4822
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
