libMPQ Problems...

[counted]

I had wowMapper working a couple of patches ago and recently went back to it now that I have better ability to generate quest data.

When i fired up my previously working version, bam. It is broken.

I traced through the code and found out that libMPQ now thinks the part *.wdt file is encrypted and can not decrypt it. I loaded the MPQ file in MPQEditor and the encrypted flag is not set.

I traced into libMPQ functions:

int32_t libmpq__block_open_offset(mpq_archive_s *mpq_archive, uint32_t file_number) {

and found that

/* check if the archive is protected some way, sometimes the file appears not to be encrypted, but it is. */
if (mpq_archive->mpq_file[file_number]->packed_offset[0] != rb) {

/* file is encrypted. */
mpq_archive->mpq_block[mpq_archive->mpq_map[file_number].block_table_indices].flags |= LIBMPQ_FLAG_ENCRYPTED;
}

is true and it is flagging the file as encrypted.

I commented this check out and wowMapper works fine again and extracts the adts that i am looking for.

Anyone have an idea what I am doing wrong or what changed in a recent patch?

thanks,

I guess this is libMPQ incorrectly detecting the patch flag as an encryption flag because afaik libMPQ doesn't handle patched files/archives.
You might want to switch to stormlib instead.

Thanks for the help. Will start on "stormMapper" tonight.
