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: When creating POSIX multivolume archives, tar may in
|
|
# some cases write an extended header at the end of one volume, and
|
|
# the corresponding ustar header at the beginning of the next volume.
|
|
# Such archives do not fully comply with the POSIX specs, but tar must
|
|
# be able to read them anyway. This is what this script tests.
|
|
#
|
|
# See function try_new_volume, in file src/buffer.c near line 1227
|
|
# for additional details.
