This is a follow up bug from bug 959047 comment 8.
To provide more general and flexible support for alignment, we can implement an API as follow, which allows different alignment size for files in a zip.
void addAlignedEntryStream(in AUTF8String aZipEntry, in PRTime aModTime,
in int32_t aCompression, in nsIInputStream aStream,
in boolean aQueue, in uint32_t aAlignSize);
For each file in zip, we need to save the aligment size in the extra field.
Below is a proposed Mozilla proprietary extra field.
Value Size Description
----- ---- -----------
0xAA01 2 bytes Tag for this "extra" block type
TSize 2 bytes Size of the store data
AlignSize 2 bytes Alignment size
Padding Variable Padding information for alignment
For more information on extra field in zip, please read "Extensible data fields" section in:
