In this change, we defined HTTP header fields we are interested in.
We only store those headers in HttpHeader object. Accessing HTTP
headers in HttpHeader object is now done through enum values.
DownloadHandlerConstants was simplified. MIME type handling in Accept
header was also reworked. DownloadContext's metalinkServerContacted_
is replaced with acceptMetalink_ and its boolean value is reverted.
RequestGroup and HttpRequest now do not hold vector of accepting
types. HttpRequest has the flag acceptMetalink_ which will be set by
the same value of DownloadContext::accpetMetalink_ and if it is true,
Metalink MIME types are added to Accept header field.
Socket::getPeerInfo() may fail if its TCP connection has already
disconnected. In this case, we log this error. The success or failure
of pooling connection should not affect the later execution of the
program.
In CreateRequestCommand, if Request object returned from getRequest()
is still sleeping, CreateRequestCommand pools it back but still holds
its reference. This makes assertion error in
UnknownLengthPieceStroage::hasMissingUnusedPiece() from
AbstractCommand::execute().
--file-allocation option can now take new value 'trunc'. 'trunc' uses
ftruncate() system call or platform-specific counterpart to truncate a
file to a specified length.
With BitTorrent or Metalink (metaurl), one RequestGroup can contain
multiple files. In this change, ensure that the sum of thoese files
must be equal or less than INT64_MAX.
Using off_t, at least, in DiskAdaptor layer is problematic because
torrent can contain under 2GiB files but total sum of those files may
exceed 2GiB limit, which makes off_t overflow in 32 bit system without
large file support. So we use int64_t in API. We'll check the file
length before download so that it does not exceed max off_t.
Use system-wide certificates for SSL. For GnuTLS it requires the
latest version, 3.0.20. OpenSSL had it for longer. This means that if
SSL library is properly configured to locate system-wide certificates
store, the user don't have to use --ca-certificate option. Also
packagers don't have to use --with-ca-bundle configure option.
