Package: lintian Version: 2.2.9 Severity: wishlist Please warn about symbols files containing #MISSING: ... These lines indicate some symbols have disappeared in newer versions of a library. The removed symbols might have been private symbols that have been hidden or they were public symbols that have been removed. Private symbols should be removed from the symbols file. Removed symbols means an ABI breakage and that version should not be packaged without reintroducing the symbols or bumping the SONAME/etc. Another alternative is that the symbols were introduced in a release candidate and removed in the final release, I guess the symbols should be removed. Normally when a symbol disappears the package will FTBFS with a message like the below. Some people seem to just patch their symbols file with the lines containing #MISSING instead of dealing with the issue properly and hopefully a lintian warning would discourage that practice. dh_makeshlibs dpkg-gensymbols: warning: some symbols disappeared in the symbols file: see diff output below dpkg-gensymbols: warning: debian/libicns1/DEBIAN/symbols doesn't match completely debian/libicns1.symbols --- dpkg-gensymbolskwkdDi 2009-04-27 13:18:21.000000000 +0800 +++ dpkg-gensymbolsnfF9Vl 2009-04-27 13:18:21.000000000 +0800 @@ -19, 7 +19, 7 @@ icns_import_family_data@Base 0.5.7 icns_init_image@Base 0.5.7 icns_init_image_for_type@Base 0.5.7 - icns_jp2_to_image@Base 0.5.7 +#MISSING: 0.5.9-1.1# icns_jp2_to_image@Base 0.5.7 icns_new_element_from_image@Base 0.5.7 icns_new_element_from_mask@Base 0.5.7 icns_read_family_from_file@Base 0.5.7 dh_makeshlibs: command returned error code 256 Here are some examples of that on lenny: $ grep MISSING /var/lib/dpkg/info/*symbols /var/lib/dpkg/info/e2fslibs.symbols:#MISSING: 1.41.1# os_tab@Base 1.37 /var/lib/dpkg/info/e2fslibs.symbols:#MISSING: 1.41.1# crc16@Base 1.41.0 /var/lib/dpkg/info/e2fslibs.symbols:#MISSING: 1.41.1# crc16_table@Base 1.41.0 /var/lib/dpkg/info/e2fslibs.symbols:#MISSING: 1.41.0# ext2fs_swap_ext_attr@Base 1.37 /var/lib/dpkg/info/e2fslibs.symbols:#MISSING: 1.41.0# ext2fs_swap_group_desc@Base 1.37 /var/lib/dpkg/info/e2fslibs.symbols:#MISSING: 1.41.0# ext2fs_swap_inode@Base 1.37 /var/lib/dpkg/info/e2fslibs.symbols:#MISSING: 1.41.0# ext2fs_swap_inode_full@Base 1.37 /var/lib/dpkg/info/e2fslibs.symbols:#MISSING: 1.41.0# ext2fs_swap_super@Base 1.37 /var/lib/dpkg/info/libblkid1.symbols:#MISSING: 1.41.1# blkid_devdirs@Base 1.34 /var/lib/dpkg/info/libblkid1.symbols:#MISSING: 1.40.7# check_for_modules@Base 1.40.6 /var/lib/dpkg/info/libblkid1.symbols:#MISSING: 1.40.7# fs_proc_check@Base 1.40.6 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_connection_failed@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_connection_failed_with_error@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_connection_succeeded@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_message_handler_handle_message@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_message_new_from_node@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_message_node_add_child_node@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_message_node_new@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_message_sub_type_to_string@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_message_type_to_string@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_proxy_connect_cb@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_sock_addrinfo_get_error_str@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_sock_get_error_str@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_sock_get_local_host@Base 1.2.3-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_sock_library_shutdown@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_ssl_base_free_fields@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_ssl_base_init@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_ssl_begin@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_ssl_close@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_ssl_free@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_ssl_func_always_continue@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_ssl_initialize@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_ssl_new@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_ssl_read@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_ssl_send@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_utils_base64_encode@Base 1.1.4-2 /var/lib/dpkg/info/libloudmouth1-0.symbols:#MISSING: 1.3.3-1# _lm_utils_generate_id@Base 1.1.4-2 /var/lib/dpkg/info/libogg0.symbols:#MISSING: 1.1.0# oggpack_adv_huff@Base 1.0rc3 /var/lib/dpkg/info/libogg0.symbols:#MISSING: 1.1.0# oggpack_look_huff@Base 1.0rc3 -- bye, pabs http://wiki.debian.org/PaulWise
