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
- Disable auto credentials by default. This is a breaking change
for clients that are using it, wittingly or not.
- New libcurl ssl option value CURLSSLOPT_AUTO_CLIENT_CERT tells libcurl
to automatically locate and use a client certificate for
authentication, when requested by the server.
- New curl tool options --ssl-auto-client-cert and
--proxy-ssl-auto-client-cert map to CURLSSLOPT_AUTO_CLIENT_CERT.
This option is only supported for Schannel (the native Windows SSL
library). Prior to this change Schannel would, with no notification to
the client, attempt to locate a client certificate and send it to the
server, when requested by the server. Since the server can request any
certificate that supports client authentication in the OS certificate
store it could be a privacy violation and unexpected.

Closes https://github.com/curl/curl/pull/6673
- Save a parallel transfer's result code only when it fails and the
transfer is not being retried.
Prior to this change the result code was always set which meant that a
failed result could be erroneously discarded if a different transfer
later had a successful result (CURLE_OK).
Before:
> curl --fail -Z https://httpbin.org/status/404https://httpbin.org/delay/10
> echo %ERRORLEVEL%

After:
> curl --fail -Z https://httpbin.org/status/404https://httpbin.org/delay/10

- New libcurl options CURLOPT_DOH_SSL_VERIFYHOST,
CURLOPT_DOH_SSL_VERIFYPEER and CURLOPT_DOH_SSL_VERIFYSTATUS do the
same as their respective counterparts.
- New curl tool options --doh-insecure and --doh-cert-status do the same
as their respective counterparts.
Prior to this change DOH SSL certificate verification settings for
verifyhost and verifypeer were supposed to be inherited respectively
from CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER, but due to a bug
were not. As a result DOH verification remained at the default, ie
enabled, and it was not possible to disable. This commit changes
behavior so that the DOH verification settings are independent and not
inherited.

Closes https://github.com/curl/curl/pull/6597
- Deduplicate the logic used by write-out and write-out json.
Rather than have separate writeLong, writeString, etc, logic for
each of write-out and write-out json instead have respective shared
functions that can output either format and a 'use_json' parameter to
indicate whether it is json that is output.
This will make it easier to maintain. Rather than have to go through
two sets of logic now we only have to go through one.
- Support write-out %{errormsg} and %{exitcode} in json.
- Clarify in the doc that %{exitcode} is the exit code of the transfer.
Prior to this change it just said "The numerical exitcode" which
implies it's the exit code of the tool, and it's not necessarily that.
Closes https://github.com/curl/curl/pull/6544
- 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
- Fix the failed truncation and failed writing body error messages to
not be shown unless error messages are shown. (ie the user has
specified -sS, or has not specified -s).
- Also prefix same error messages with "curl: ", for example:
curl: (23) Failed to truncate, exiting
Prior to this change the failed truncation error messages would be shown
if not -s, but did not account for -sS which should show.
Prior to this change the failed writing body error messages would be
shown always.

We currently use both spellings the british "behaviour" and the american

it's worth dropping the british name.

The match of the "-q" option (short for "--disable") should:
a) allow concatenation with other single-letters; and
b) be case-sensitive, lest confusing with "-Q" ("--quote")

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

Previously, it would pass on a define (int) which could make libcurl
read junk as a value - which prevented the CURLOPT_IPRESOLVE option to
"take". This could then make test 2100 do two DoH requests instead of
one!

The previous sleep for retries would block all other concurrent
transfers. Starting now, the retry will instead be properly marked to
not get restarted until after the delay time but other transfers can
still continue in the mean time.
Closes#5917
Background:
148534d added CURLSSLOPT_NATIVE_CA to use the Windows OS certificate
store in libcurl w/ OpenSSL on Windows. CURLSSLOPT_NATIVE_CA overrides
CURLOPT_CAINFO if both are set. The curl tool will fall back to
CURLSSLOPT_NATIVE_CA if it could not find a certificate bundle to set
via CURLOPT_CAINFO.
Problem:
libcurl may be built with hardcoded paths to a certificate bundle or
directory, and if CURLSSLOPT_NATIVE_CA is used then those paths are
ignored.
Solution:
A solution is still being discussed but since there's an impending
release this commit removes using CURLSSLOPT_NATIVE_CA in the curl tool.

curl would previously show "curl: Saved to filename 'name from header'"
if -J was used and a name was picked from the Content-Disposition
header. That output could interfer with other stdout output, such as -w.
This commit removes that output line.

- Stick to a single unified way to use structs
- Make checksrc complain on 'typedef struct {'

Closes#5338
- use `wmain` instead of `main` when `_UNICODE` is defined [0]
- define `argv_item_t` as `wchar_t *` in this case
- use the curl_multibyte gear to convert the command-line arguments to
UTF-8
This makes it possible to pass parameters with characters outside of
the current locale on Windows, which is required for some tests, e.g.
the IDN tests. Out of the box, this currently only works with the
Visual Studio project files, which default to Unicode, and winbuild
with the `ENABLE_UNICODE` option.
