A separate map (bufmap) provides information for creating multi-volume continuation headers. * src/buffer.c (bufmap): New struct. (bufmap_head, bufmap_tail, inhibit_map): New variables. (mv_begin_write): New function. (mv_begin): Rename to mv_begin_read. Rewrite using mv_begin_write. All callers changed. (mv_total_size): Remove. (bufmap_locate, bufmap_free, bufmap_reset): New functions. (_flush_write): Update bufmap. (close_archive): Free bufmap. (add_chunk_header): Take a bufmap argument. (gnu_add_multi_volume_header): Likewise. (add_multi_volume_header): Likewise. (_gnu_flush_write): Rewrite using bufmap. (real_s_name, real_s_totsize) (real_s_sizeleft) (save_name, save_totsize, save_sizeleft): Removed. All uses updated. (mv_size_left): Update bufmap_head. (mv_end): Rewrite. (multi_volume_sync): Remove. * src/common.h (mv_begin_write): New prototype. (mv_begin): Rename to mv_begin_read. * src/create.c: Use mv_begin_write instead of mv_begin. Remove calls to mv_size_left and mv_end. * src/sparse.c: Likewise. * tests/multiv07.at: Close stdin. * tests/spmvp00.at: Update AT_KEYWORDS. * tests/spmvp10.at: Likewise. * tests/multiv08.at: New testcase. * tests/Makefile.am, tests/testsuite.at: Add multiv08.at.

# Description: Tar 1.23 would in some cases silently fail to create
|
|
# a continuation header in multivolume archives.
|
|
#
|
|
# In this testcase, the file `a' is 18.5 blocks long and the file `b'
|
|
# is 19.5 blocks long.
