Version number is removed in order to make this info consistent with
how we do it with other MS and Linux system libraries for which we don't
provide this info.
Identifier changed from 'WinSSPI' to 'schannel' given that this is the
actual provider of the SSL/TLS support. libcurl can still be built with
SSPI and without SCHANNEL support.
Added Windows SSPI version information to the curl version string when
SCHANNEL SSL is not enabled, as the version of the library should also
be included when SSPI is used to generate security contexts.
Removed SSPI from the feature list as the features are GSS-Negotiate,
NTLM and SSL depending on the usage of the SSPI library.
Additionally, make hash checking ability mandatory in order to allow metalink
support in curl.
A command line option could be introduced to skip hash checking at runtime,
but the ability to check hashes should always be built-in when providing
metalink support.
Metalink file contains several hash types of checksums, such as
md5, sha-1, sha-256, etc. To deal with these checksums, I created
abstraction layer based on lib/curl_md5.h and
lib/md5.c. Basically, they are almost the same but I changed the
code so that it is not hash type dependent. Currently,
GNUTLS(nettle or gcrypt) and OpenSSL functions are supported.
Checksum checking is done by reopening download file. If there
is an I/O error, the current implementation just prints error
message and does not try next resource.
In this patch, the supported hash types are: md5, sha-1 and sha-256.
Filenames contained in Metalink file can include directory information.
Filenames are unique in Metalink file, taking into account the directory
information. So we need to create the directory hierarchy.
Curl has --create-dirs option, but we create directory hierarchy for
Metalink downloads regardless of the option value.
This patch also put metalink int variable outside of HAVE_LIBMETALINK
guard. This reduces the number of #ifdefs.
This change adds experimental Metalink support to curl.
To enable Metalink support, run configure with --with-libmetalink.
To feed Metalink file to curl, use --metalink option like this:
$ curl -O --metalink foo.metalink
We use libmetalink to parse Metalink files.
To achieve this, first new structure HeaderData is defined to hold
necessary data to perform header-related work. Then tool_header_cb now
receives HeaderData pointer as userdata. All header-related work
(currently, dumping header and Content-Disposition inspection) are done
in this callback function. HeaderData.outs->config is used to determine
whether each work is done.
Unit tests were also updated because after this change, curl code always
sets CURLOPT_HEADERFUNCTION and CURLOPT_HEADERDATA.
Tested with -O -J -D, -O -J -i and -O -J -D -i and all worked fine.
Explicit conversion to 'long' of curl_easy_setopt() third argument for options
CURLOPT_HTTPAUTH and CURLOPT_PROXYAUTH given that this is how its bitmasks are
docummented to be used.
By comparing if a different "progress point" is reached or not since the
previous update, the progress function callback for this now avoids many
superfluous screen updates. This has the nice side-effect that it fixes
a problem that causes a second progress meter line.
The second line output happened because when we use the -# progress
meter, we force a newline output after the transfer in the main loop in
curl, but when libcurl calls the progress callback from
curl_easy_cleanup() it would then output the progress display
again. Possibly the naive newline output is wrong but this optimization
was suitable anyway...
