libarchive wrongly read rar package with a microsoft word in it

[wtiandong]

Hi all,
I compiled the latest libarchive and had a try. I feed a rar (v2.9) package with a microsoft word document (.docx) in it to the lib, the lib returns me a wrong file list. Here're the details:

code:
`

struct archive *a;
struct archive_entry *entry;
int r;
a = archive_read_new();
archive_read_support_filter_all(a);
archive_read_support_format_all(a);
NSString * filePath = [[NSBundle mainBundle] pathForResource:@"Desktop_aa.rar" ofType:nil];
r = archive_read_open_filename(a, [filePath UTF8String], 10240); // Note 1
if (r != ARCHIVE_OK) {
    NSLog(@"open failed\n");
}
while (archive_read_next_header(a, &entry) == ARCHIVE_OK) {
    NSLog(@"%s",archive_entry_pathname(entry));
    archive_read_data_skip(a);  // Note 2
}
r = archive_read_free(a);  // Note 3
if (r != ARCHIVE_OK) {
    NSLog(@"free failed!");
}

`

and the Log is:

it seems that it takes word document as a compressed package? But it's OK for zip/tar/tar.gz ...

[kientzle]

Could you provide more details?

How did you create the rar file in question?

When you ask another program (such as unrar) to list the files, what does it show?

Can you provide us with a (small) example file to reproduce this problem?

hi kientzle,
http://pan.baidu.com/s/1eSM9qWM
here is the rar package. I uploaded it to a cloud storage website, just click the button on the upper right (with a down arrow icon) and then you can download it and have a inspection. Just two pictures and a docx in it.

I noticed that this docx is generated by an MS Word compliant software called Kingsoft WPS. I can open it with MS Word. But I can also open it with vim. And it shows that it looks like a zip file ... while docx generated by MS Word looks like a binary file with vim....

The Office XML format is using a zip wrapper, just like ODT.
