To add the ability to resume downloading a partially downloaded
file
which is downloaded from the beginning:
* src/FileAllocator.h: Made abstract class. New
DefaultFileAllocator
takes this role.
* src/main.cc: Added -c option.
* src/BitfieldMan.h, src/BitfieldMan.cc (setBitRange): New
function.
* src/DiskWriter.h (openExistingFile): Added totalLength
argument.
* src/prefs.h (PREF_CONTINUE): New definition.
* src/SegmentMan.h, src/SegmentMan.cc (markPieceDone): New
function.
* src/DefaultDiskWriter.cc
(createNewDiskWriter): Add GlowFileAllocator to the new object.
* src/AbstractDiskWriter.h
(glowFileAllocator): New variable.
* src/AbstractDiskWriter.cc
(openExistingFile): Now preallocate file space from the end of
the
existing file if totalLength argument is specified and grater
than 0.
* src/UrlRequestInfo.cc: If -c option is specified and the file
to download exists in local, continue the download of the file.
--allow-overwrite=true is assumed in this context.
* src/DefaultFileAllocator.h, src/DefaultFileAllocator.cc: New
class.
* src/GlowFileAllocator.h, src/GlowFileAllocator.cc: New class.
Throw exception if --check-integrity=true is specified but chunk
checksums are not provided:
* src/UrlRequestInfo.cc
