|
|
|
+
|
|
|
+ Support for incremental formats in pax archives.
|
|
|
+ Fixed POSIX compatibility of `sparse' extended header keywords.
|
|
|
+
|
|
|
+ * src/common.h (dumpdir_size,get_gnu_dumpdir)
|
|
|
+ (xheader_string_begin,xheader_string_add)
|
|
|
+ (xheader_string_end): New functions.
|
|
|
+ * src/create.c (dump_dir0): Handle incremental backups in pax
|
|
|
+ archives.
|
|
|
+ * src/incremen.c (dumpdir_size, get_gnu_dumpdir): New functions.
|
|
|
+ (purge_directory): Use stat_info.dumpdir instead of getting its
|
|
|
+ value explicitely.
|
|
|
+ * src/list.c (list_archive): Handle incremental backups in pax
|
|
|
+ format.
|
|
|
+ (decode_header): Initialize stat_info.dumpdir
|
|
|
+ * src/sparse.c (sparse_diff_file): Bugfix: set seekable.
|
|
|
+ (pax_dump_header): Store sparse map in GNU.sparse.map. If this
|
|
|
+ variable has been explicitely deleted, use GNU.sparse.offset/
|
|
|
+ GNU.sparse.numbytes variables.
|
|
|
+ * src/tar.c (decode_options): Incremental options are allowed with
|
|
|
+ --format=pax
|
|
|
+ (tar_stat_destroy): Free dumpdir
|
|
|
+ * src/tar.h (struct tar_stat_info.dumpdir): New member.
|
|
|
+ * src/xheader.c (xheader_keyword_deleted_p): Remove static
|
|
|
+ qualifier.
|
|
|
+ (struct xhdr_tab.decoder): Change prototype. POSIX allows string
|
|
|
+ values to contain embedded nulls, so take an extra argument
|
|
|
+ specifying the length of the string.
|
|
|
+ (decx,decg,dummy_decoder,atime_decoder,gid_decoder)
|
|
|
+ (gname_decoder,linkpath_decoder,ctime_decoder,mtime_decoder)
|
|
|
+ (path_decoder,size_decoder,uid_decoder,uname_decoder)
|
|
|
+ (sparse_size_decoder,sparse_numblocks_decoder)
|
|
|
+ (sparse_offset_decoder,sparse_numbytes_decoder): Likewise.
|
|
|
+ (decode_record): Pass value length to the handler
|
|
|
+ (run_override_list): Pass value length to the decoder
|
|
|
+ (xheader_print_n): New function
|
|
|
+ (xheader_print): Rewritten using xheader_print_n
|
|
|
+ (xheader_finish): Do not rely om strlen to compute the length of
|
|
|
+ the collected string: it can contain embedded nulls
|
|
|
+ (xheader_string_begin,xheader_string_add,xheader_string_end): New
|
|
|
+ functions.
|
|
|
+ (sparse_map_decoder,dumpdir_coder,dumpdir_decoder): New
|
|
|
+ functions. Handle GNU.sparse.map and GNU.dumpdir variables.
|
|
|
+ (xhdr_tab): Add new variables.
|
|
|
+
|
|
|
+ * tests/incr01.at: Test gnu, oldgnu, and posix formats
|
|
|
+ * tests/incremental.at: Likewise
|
|
|
+
|
|
|

|
|
* src/xheader.c (strtoimax, strtoumax): Remove decls; now done
