|
|
Input: list of files to copy (ctor).
|
|
Output: list of files to rename in order to complete the transaction (copyFinished signal).
|
|
|
|
Example (using a single file):
|
|
|
|
Input source: F:\QUAKE3\baseq3\pak0.pk3
|
|
Input dest: C:\Program Files (x86)\Quake III Arena\baseq3\pak0.pk3
|
|
|
|
Source is copied to dest, but the destination file is renamed by prepending a random prefix, e.g. 34d8f_pak0.pk3.
|
|
|
|
Output source: C:\Program Files (x86)\Quake III Arena\baseq3\34d8f_pak0.pk3
|
|
Output dest: C:\Program Files (x86)\Quake III Arena\baseq3\pak0.pk3
|
|
|
|
The transaction is completed by deleting output dest and renaming output source to output dest.
|
|
|
|
If the worker is cancelled, all created files are deleted.
