Both `lt::create_torrent` constructor and `lt::create_torrent::generate()`
can throw an exception so we need to handle it to prevent the app from crashing.
- warning C4267: 'initializing': conversion from 'size_t' to 'int', possible loss of data
Caused by mismatch between size_type of std and Qt containers. It is safe to cast to int as all of those containers hold low number of objects.
Define "torrent ID" concept, which is either a SHA1 hash for torrents of version 1,
or a SHA256 hash (truncated to SHA1 hash length) for torrents of version 2.
Add support for native libtorrent2 info hashes.
Previously we need a file buffer that is as large as the file size and
this could be a problem when user has less free memory available or
having very large data. Now with the help of `FileOutputIterator`,
we can have a much smaller, fixed size immediate file buffer and also
the code looks nice with `lt::bencode()`.
Unlike "toNativePath" which name clearly reflects the function result
"fromNativePath" has no such clear meaning.
Since this function converts path into uniform format "toUniformPath"
is better name.
`QIODevice::read(qint64 maxSize)` will allocate full `maxSize` of memory no matter
what the real file size was, this caused users to experience out-of-memory
exception on 32-bit qbt.
Also handle the OOM execption if it still fails.
Closes#9064, #9075, #9130, #9239, #9246, #9279.
`torrent_info` constructor has default limits that can't be changed via
parameters, so we handle the loading process manually and explicitly
specifiy the limits to `bdecode()`.
The token_limit is also changed to 10000000.
qDebug(), qInfo(), qWarning(), qCritical(), qFatal() expect %s arguments
to be UTF-8 encoded, while qPrintable() converts to local 8-bit encoding.
Therefore qUtf8Printable() should be used for logging strings instead of
qPrintable().
Now getting piece information for a specific torrent is possible via:
* Returns an array of states (integers) of pieces in order. Defined as:
"0=not downloaded", "1=downloading", "2=downloaded".
GET /query/getPieceStates/<torrent_hash>
* Returns an array of hashes (strings) of pieces in order:
GET /query/getPieceHashes/<torrent_hash>
