Add a single, central base64 decoder

2022-11-17T23:58:13+00:00

Similar to the hex blob decoder, we need this once for tar and once for the filemap xattr parser. Simply add a single, central implementation to libutil, with a simple unit test, and then use it in both libtar and gensquashfs. Signed-off-by: David Oberhollenzer

Add a single, central hex blob decoder

2022-11-17T23:58:07+00:00

Since we need it twice (once for tar, once for the filemap xattr parser), add a single, central implementation to libutil, add a unit test for that implementation and then use it in both libtar and gensquashfs. Signed-off-by: David Oberhollenzer

Cleanup: split libtar header, move to sub directory

2022-07-08T17:17:35+00:00

Some of the on-disk format internals are moved to a separate header and some of the stuff from internal.h is moved to that format header. C++ guards are added in addtion. Everything PAX related is moved to pax_header.c, some internal functions are marked as static. Signed-off-by: David Oberhollenzer

Cleanup: remove struct stat from libtar

2022-03-30T20:31:30+00:00

The idea was originally to use struct stat in the libfstree code, so we can simply hose data read from a directory into the fstree_t. The struct was then also used with libtar, for simpler interoperation, but it turned out to introduce a lot of platform quirks and causes more trouble than it's worth.

Cleanup: table driven pax header parsing

2022-03-30T20:31:30+00:00

Instead of having a long if-else-if chain, replace the PAX header field parsing with a table driven approach. Altough it is more code, it is hopefully more readable, maintainable, extensible and it dedupliates some of the value parsing code. The GNU.sparse parsing is left as is, because it requires maintaining state. Signed-off-by: David Oberhollenzer

Cleanup: pax header parsing

2022-03-30T20:31:30+00:00

Split the key/value pairs right in the header and terminate the key name. This way, some of the magic numbers can be eliminated. Signed-off-by: David Oberhollenzer

Fix printf format specifiers used for generating tarballs

2021-07-09T16:14:01+00:00

When processing files > 4G, using "%o" truncates the result and the tarball is not readable. This should have been discovered when auto-patching the printf format specifiers, but a cast was added instead and the issue was overlooked. This commit replaces the down-cast and printf format specifiers. Signed-off-by: David Oberhollenzer
