ngtcp2: Add an error code for QUIC connection errors

2020-01-11T23:19:32+00:00

- Add new error code CURLE_QUIC_CONNECT_ERROR for QUIC connection
  errors.

Prior to this change CURLE_FAILED_INIT was used, but that was not
correct.

Closes https://github.com/curl/curl/pull/4754

multi: Change curl_multi_wait/poll to error on negative timeout

2020-01-11T23:16:28+00:00

- Add new error CURLM_BAD_FUNCTION_ARGUMENT and return that error when
  curl_multi_wait/poll is passed timeout param < 0.

Prior to this change passing a negative value to curl_multi_wait/poll
such as -1 could cause the function to wait forever.

lib: fix compiler warnings with `CURL_DISABLE_VERBOSE_STRINGS`

strerror: Fix compiler warning "empty expression"

2019-12-18T19:10:23+00:00

- Remove the final semi-colon in the SEC2TXT() macro definition.

Before:  #define SEC2TXT(sec) case sec: txt = #sec; break;

After:   #define SEC2TXT(sec) case sec: txt = #sec; break

Prior to this change SEC2TXT(foo); would generate break;; which caused
the empty expression warning.

strerror: Add Curl_winapi_strerror for Win API specific errors

2019-12-01T23:12:36+00:00

- In all code call Curl_winapi_strerror instead of Curl_strerror when
  the error code is known to be from Windows GetLastError.

Curl_strerror prefers CRT error codes (errno) over Windows API error
codes (GetLastError) when the two overlap. When we know the error code
is from GetLastError it is more accurate to prefer the Windows API error
messages.

multi: add curl_multi_wakeup()

2019-11-25T14:45:56+00:00

This commit adds curl_multi_wakeup() which was previously in the TODO
list under the curl_multi_unblock name.

On some platforms and with some configurations this feature might not be
available or can fail, in these cases a new error code
(CURLM_WAKEUP_FAILURE) is returned from curl_multi_wakeup().

Fixes #4418
Closes #4608

include: make CURLE_HTTP3 use a new error code

2019-11-21T22:16:29+00:00

To avoid potential issues with error code reuse.

quiche: reject headers in the wrong order

Pseudo header MUST come before regular headers or cause an error.

strerror: Fix an error looking up some Windows error strings

2019-11-09T23:07:59+00:00

- Use FORMAT_MESSAGE_IGNORE_INSERTS to ignore format specifiers in
  Windows error strings.

Since we are not in control of the error code we don't know what
information may be needed by the error string's format specifiers.

Prior to this change Windows API error strings which contain specifiers
(think specifiers like similar to printf specifiers) would not be shown.
The FormatMessage Windows API call which turns a Windows error code into
a string could fail and set error ERROR_INVALID_PARAMETER if that error
string contained a format specifier. FormatMessage expects a va_list for
the specifiers, unless inserts are ignored in which case no substitution
is attempted.

vauth: Use CURLE_AUTH_ERROR for auth function errors

2019-08-14T07:14:01+00:00

- Add new error code CURLE_AUTH_ERROR.

Prior to this change auth function errors were signaled by
CURLE_OUT_OF_MEMORY and CURLE_RECV_ERROR, and neither one was
technically correct.
