项目描述

Lbzip2 is a parallel, SMP-based, bzip2-compatible compression utility, with a commandline resembling that of the original bzip2. It is usable both on its own and as a filter passed to GNU tar with the "--use-compress-program" option. It uses Gnulib, and its building and testing process is managed by the GNU build system. Starting with release 2.0, lbzip2 is independent of libbz2 and features yambi, an independent BWT compression stack with improved speed and robustness.

此版本的作品围绕一个GNU / kFreeBSD标准兼容的问题。慈善/ kFreeBSD没有界定一些溪流有关的访问Errno由SUSv2授权宏。因此，lbzip2，0.18不能建立在GNU / kFreeBSD。这个版本如果这些（和其他一些）宏之前确定对它们的依赖检查。
标签: Minor bugfixes
This release works around a GNU/kFreeBSD standards-compliance problem. GNU/kFreeBSD does not define some STREAMS-related errno macros mandated by SUSv2. Consequently, lbzip2-0.18 cannot be built on GNU/kFreeBSD. This version checks if those (and some other) macros are defined before relying on them.

健全性检查，同时添加到解压缩。输入文件操作现在得以消除。的-保持和-组的办法增加了。所有者，组，权限位，访问时间，修改时间复制到正常输出文件。采伐清理和国内到信息，警告和致命水平分类。一个单独的出口地位的情况介绍了警告消息时，已打印。解压缩鲁棒性测试，重新执行。撰文终于取代lbzip2在他的系统bzip2压缩。
标签: Major feature enhancements
Sanity checks were added to both decompressors. Input FILE operands
are now removed. The --keep and --force options were added. Owner, group,
permission bits, access time, modification time are copied to regular
output files. Logging was cleaned up and internally categorized into
INFO, WARNING, and FATAL levels. A separate exit status was introduced
for the case when a warning message was printed. The decompressor
robustness tests were re-executed. The author has finally replaced bzip2
with lbzip2 on his system.

未初始化的领域是在访问中的堆栈结构赋值表达式。从理论上讲，这可能也会引起读访问捕获的意见。由于这些领域没有初始化，因为他们根本没有使用首先，这可携性错误是固定不引入这些领域的专用结构。
标签: Code cleanup
Uninitialized fields were accessed on the stack in a structure assignment expression. Theoretically, this might have entailed read accesses to trap representations. Since those fields weren't initialized because they weren't used at all in the first place, this portability bug was fixed by introducing a dedicated structure without those fields.

非经常输入文件在命令行上通过的将被跳过（符号链接得到遵守，因为lbzip2不会删除输入文件）。而不是退出，lbzip2跳过输入文件在命令行，它无法打开，或者它不能创造相应的输出文件的通过。标准输出也关闭了- stdout和文件操作，不仅在过滤模式。信号处理已清理; lbzip2现在可以在跳绳连续多个文件中断。编写一个错误消息管道破裂不会导致在一个不完整的输出文件了。
标签: Minor bugfixes
Non-regular input files passed on the command line are skipped (symbolic links are followed, because lbzip2 doesn't remove input files). Instead of exiting, lbzip2 skips input files passed on the command line that it cannot open, or for which it cannot create the corresponding output files. Standard output is also closed with --stdout and file operands, not just in filter mode. Signal handling has been cleaned up; lbzip2 can now be interrupted during skipping many files in a row. Writing an error message to a broken pipe doesn't result in an incomplete output file anymore.

压缩功能，例如可设置块大小和文件操作的工作得到执行。 lbzip2现在可以被认为是多线程，命令行兼容了bzip2在大多数情况下更换。 Lbzip2从来没有删除或覆盖的文件，但是。对于较早慈善getconf错误的替代方案是扩大在大文件的支持为基础，EGLIBC脚本。的发展状况是退化到测试版。
标签: Major feature enhancements
Features like settable compression block size and working with file operands were implemented. lbzip2 can now be considered a multi-threaded, command-line compatible replacement for bzip2 in most situations. Lbzip2 never deletes or overwrites files, however. The workaround for an earlier GNU getconf bug was extended to EGLIBC in the large file support build script. The development status was degraded to beta.
