2012-10-22metalink/md5: Use CommonCrypto on Apple operating systemsNick Zitzmann
Previously the Metalink code used Apple's CommonCrypto library only if curl was built using the --with-darwinssl option. Now we use CommonCrypto on all Apple operating systems including Tiger or later, or iOS 5 or later, so you don't need to build --with-darwinssl anymore. Also rolled out this change to libcurl's md5 code.

2012-10-01tool_metalink.c: Filtered resource URLs by typeTatsuhiro Tsujikawa
In Metalink v3, the type attribute of url element indicates the type of the resource the URL points to. It can include URL to the meta data, such as BitTorrent metainfo file. In Curl, we are not interested in these meta data URLs. Instead, we are only interested in the HTTP and FTP URLs. This change filters out non-HTTP and FTP URLs. If we don't filter out them, it will be downloaded by curl and hash check will fail if hash is provided and next URL will be tried. This change will cut this useless network transfer.
2012-09-12tool_metalink.c: Added name of validation hash to messagesMarc Hoersken
This makes it easier to debug broken hashes or hash functions.
2012-09-11wincrypt: Fixed cross-compilation issues caused by include nameMarc Hoersken
For some reason WinCrypt.h is named wincrypt.h under MinGW.
2012-09-11tool_metalink.c: Added support for Microsoft Windows CryptoAPIMarc Hoersken
Since Metalink support requires a crypto library for hash functions and Windows comes with the builtin CryptoAPI, this patch adds that API as a fallback to the supported crypto libraries. It is automatically used on Windows if no other library is provided.
2012-09-11tool_metalink.c: Fixed error: 'O_BINARY' undeclaredMarc Hoersken
Check for O_BINARY which is not available on every system.
2012-09-11tool_metalink.c: Fixed validation of binary files containing EOFMarc Hoersken
Since Windows/MinGW threat 0x1A as the EOF character, reading binary files which contain that byte does not work using text mode. The read function will only read until the first 0x1A byte. This means that the hash is not computed from the whole file and the final validation check using hash comparision fails.
2012-08-08metalink: Un-broke the build when building --with-darwinsslNick Zitzmann

2012-06-28Metalink: message updatesTatsuhiro Tsujikawa
Print "parsing (...) OK" only when no warnings are generated. If no file is found in Metalink, treat it FAILED. If no digest is provided, print WARNING in parse_metalink(). Also print validating FAILED after download. These changes make tests 2012 to 2016 pass.

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.
2012-06-08metalink: restore some includesDaniel Stenberg
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.

2012-05-26Disable hash check if neither OpenSSL nor GNUTLS is installed.Tatsuhiro Tsujikawa
2012-05-26Minimize usage of structs from libmetalinkTatsuhiro Tsujikawa
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.
2012-05-26Fixed segmentation fault when Metalink has no valid file or no resource.Tatsuhiro Tsujikawa
2012-05-26Support media-type parameter in Content-TypeTatsuhiro Tsujikawa
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.
