The moment we write the block containing the partition table
Windows services will start accessing the SD card and write data
to "System volume information" folder.
If others are writing to disk concurrently this may or may not
affect our ability to eject the drive.
Stop StorSvc temporarily between us writing the partition table
(saved for last) and ejecting the SD card, just in case.
Ref #75
For reasons unknown the device write statistics sometimes report
higher numbers than the number of bytes we wrote to the device on
some hardware. Causing write percentage in progressbar text
to exceed 100%
Maximize amount of bytes to what we wrote to the device.
This do will result in unreliable write progress on these devices
(it will then show amount of bytes written to cache instead of
what made it to device yet)
Closes#82
- Qt thinks UNC URLs should look like: file://1.2.3.4/share/file.img
libcurl likes them: file:////1.2.3.4/share/file.img
So correct that.
- Mention it is an unspecified libcurl error if libcurl passes us
an error code with an empty error message string.
Closes#65
Modern CPUs have special instructions to accelerate computing
SHA hashes.
The Qt QCryptographicHash code is standard C, so not taking
advantage of those though.
Outsource the hashing to OpenSSL that does.
Shaves off some seconds during verification stage.
- Use larger buffer size when writing uncompressed files
(was libcurl's default of 16 kb, change it to 128 kb)
- Uncompress the next MB of data, while it is hashing/writing to
disk in seperate thread.
