2012-06-21curl: Made --metalink option toggle Metalink functionalityTatsuhiro Tsujikawa
In this change, --metalink option no longer takes argument. If it is specified, given URIs are processed as Metalink XML file. If given URIs are remote (e.g., http URI), curl downloads it first. Regardless URI is local file (e.g., file URI scheme) or remote, Metalink XML file is not written to local file system and the received data is fed into Metalink XML parser directly. This means with --metalink option, filename related options like -O and -o are ignored. Usage examples: $ curl --metalink http://example.org/foo.metalink This will download foo.metalink and parse it and then download the URI described there. $ curl --metalink file://foo.metalink This will parse local file foo.metalink and then download the URI described there.
2012-06-21curl: Refactored metalink_checksumTatsuhiro Tsujikawa
When creating metalink_checksum from metalink_checksum_t, first check hex digest is valid for the given hash function. We do this check in the order of digest_aliases so that first good match will be chosen (strongest hash function available). As a result, the metalinkfile now only contains at most one metalink_checksum because other entries are just redundant.

Commit eeeba1496cbca removed them and thus broke my Linux build
2012-06-08metalink: build fixes and adjustments IIYang Tse
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.

2012-05-26Check checksum of downloaded file if checksum is availableTatsuhiro Tsujikawa
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.

2012-05-26metalink: parse downloaded Metalink fileTatsuhiro Tsujikawa
Parse downloaded Metalink file and add downloads described there. Fixed compile error without metalink support.
2012-05-26metalink: show help message even if disabledTatsuhiro Tsujikawa
Print message if --metalink is used while metalink support is not enabled. Migrated Metalink support in tool_operate.c and removed operatemetalink().
2012-05-26Support Metalink.Tatsuhiro Tsujikawa
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.
