UnRAR logic replaces directory symlinks found within archive file entry file paths with actual directories by deleting them after they're extracted. Unfortunately, this logic extends to deleting existing directories if you set the `DestName` instead of the `DestPath` in this API: rc = RARProcessFile(hArchive, RAR_EXTRACT, NULL, destFilePath); In the future UnRAR may change to disable the `LinksToDirs()` feature if using the `DestName` parameter. In the meantime, this commit completely disables it for our use case.
This is a cherry-pick of commit 24f225c Modification to unrar codebase allowing skipping of files within Solid archives when parsing in extraction mode, enabling us to skip encrypted files while still scanning metadata and potentially scanning unencrypted files later in the archive.
Prevent allocating more than 1GB regardless of what is requested. RAR dictionary sizes may not be larger than 1GB, at least in the current version. This is a cherry-pick of commit 9b444e7
