Hi, While I was testing jca@'s diff to make the pax format the default for tar(1), I ran into the following bug in the code that reads extended headers. (To be clear: this has nothing to do with the code that *writes* extended headers and/or jca@'s diff.)
If the file name of the file in the archive is too long, pax and tar will say: pax: Extended header record length 513 is out of range The problem appears if one extended header record exceeds 512 bytes. Below is a test case. If the file name is 502 bytes long, the length of the extended header record is 512 bytes and all is fine. If the file name is 503 bytes, one byte longer, the extended header record will be 513 bytes and the error message mentioned above appears. If we want this to work, rd_xheader() probably needs to be fixed.
