Ok, we discovered that the commit object actually contains the tree
object's sha1, by reading its contents with python zlib library.
So the bug must be with our java code (we're building a java lib).
Is there any non-standard issue in git's zlib compression? We're
decompressing its contents with java default zlib api, so it should
work normally, here's our code, that's printing that wrong output:
File obj = new File(".git/objects/25/0f67ef017fcb97b5371a302526872cfcadad21");
InflaterInputStream inflaterInputStream = new InflaterInputStream(new
I know that here it's not the right place to ask about java issues,
but we would appreciate any help any help.
