[zypp-devel] Found bug in RPM... should I report? Plans for RPM 4.7?
Hi, I'm playing with rpmlib and it seems to me that headerRead() fails. I could open a bug report... upstream would not accept it, and not sure if it makes sense to open it for openSUSE. What are the plans for RPM 4.7 (or 5.x)? Will be used in 11.2? The problem is that in this simple code headerRead always returns NULL. Isn't easy to debug optimized code but it seems the HEADER_MAGIC_YES detection fails (with HEADER_MAGIC_NO fails in another header check). #include <rpm/rpmlib.h> int main(int argc, char ** argv) { Header h; FD_t fdi; fdi = Fopen(argv[1], "r"); if (Ferror(fdi)) { fprintf(stderr, "cannot open %s: %s\n", argv[1], Fstrerror(fdi)); exit(EXIT_FAILURE); } h = headerRead(fdi, HEADER_MAGIC_YES); if (!h) { fprintf(stderr, "headerRead error: %s\n", Fstrerror(fdi)); exit(EXIT_FAILURE); } Fclose(fdi); } -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

The plan is to go to 4.7 for 11.2.

Shouldn't you skip the lead first, i.e. call readLead()? You probably also need to read the signarures with rpmReadSignature().

The plan is to go to 4.7 for 11.2.
There is any RPM 4.7 package available already to test?

Now I have to go, but I will check. Makes sense, I just supposed it would skip them by itself. -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org
