- Add support services without region and service prefixes in
the URL endpoint (ex. Min.IO, GCP, Yandex Cloud, Mail.Ru Cloud Solutions, etc)
by providing region and service parameters via aws-sigv4 option.
- Add [:region[:service]] suffix to aws-sigv4 option;
- Fix memory allocation errors.
- Refactor memory management.
- Use Curl_http_method instead() STRING_CUSTOMREQUEST.
- Refactor canonical headers generating.
- Remove repeated sha256_to_hex() usage.
- Add some docs fixes.
- Add some codestyle fixes.
- Add overloaded strndup() for debug - curl_dbg_strndup().
- Update tests.
Closes#6524
The script warns if the length of $opt and $desc is > 78. However, these
two variables are on totally separate lines so the check makes no sense.
Also the $bitmask field is totally forgotten. Currently this leads to
two warnings within `--resolve` and `--aws-sigv4`.
Closes#6438
We currently use both spellings the british "behaviour" and the american
"behavior". However "behavior" is more used in the project so I think
it's worth dropping the british name.
Closes#6395
Extend the syntax of CURLOPT_RESOLVE strings: allow using a '+' prefix
(similar to the existing '-' prefix for removing entries) to add
DNS cache entries that will time out just like entries that are added
by libcurl itself.
Append " (non-permanent)" to info log message in case a non-permanent
entry is added.
Adjust relevant comments to reflect the new behavior.
Adjust documentation.
Extend unit1607 to test the new functionality.
Closes#6294
Paused transfers should not be stopped due to slow speed even when
CURLOPT_LOW_SPEED_LIMIT is set. Additionally, the slow speed timer is
now reset when the transfer is unpaused - as otherwise it would easily
just trigger immediately after unpausing.

In particular, these ones can help a user to create its own error
message when one or transfers fail.
writeout: add 'onerror', 'url', 'urlnum', 'exitcode', 'errormsg'
onerror - lets a user only show the rest on non-zero exit codes
url - the input URL used for this transfer
urlnum - the numerical URL counter (0 indexed) for this transfer
exitcode - the numerical exit code for the transfer
errormsg - obvious

It is a security process for HTTP.
It doesn't seems to be standard, but it is used by some cloud providers.

GCP (I didn't test that this code work with GCP though):
https://cloud.google.com/storage/docs/access-control/signing-urls-manually
most of the code is in lib/http_v4_signature.c
Information require by the algorithm:
- The URL
- Current time
- some prefix that are append to some of the signature parameters.
The data extracted from the URL are: the URI, the region,
the host and the API type
example:
https://api.eu-west-2.outscale.com/api/latest/ReadNets
~~~ ~~~~~~~~ ~~~~~~~~~~~~~~~~~~~
^ ^ ^
/ \ URI
API type region
Small description of the algorithm:
- make canonical header using content type, the host, and the date
- hash the post data
- make canonical_request using custom request, the URI,
the get data, the canonical header, the signed header
and post data hash
- hash canonical_request
- make str_to_sign using one of the prefix pass in parameter,
the date, the credential scope and the canonical_request hash
- compute hmac from date, using secret key as key.
- compute hmac from region, using above hmac as key
- compute hmac from api_type, using above hmac as key
- compute hmac from request_type, using above hmac as key
- compute hmac from str_to_sign using above hmac as key
- create Authorization header using above hmac, prefix pass in parameter,
the date, and above hash

This option sets the (octal) mode to use for the remote file when one is
created, using the SFTP, SCP or FILE protocols. When not set, the
default is 0644.
