git log -L 没有差异

我正在尝试使用 git log -L <start>,<end>:<filename>但我希望输出非常有限(实际上只是散列)。虽然 --pretty 以我想要的格式打印提交信息,但我没有找到不显示差异的方法...

例如在 linux-next 上,我尝试的是:

git log --pretty=format:"%H" -s -L 70,70:./arch/x86/include/asm/irqflags.h

其中(根据联机帮助页)-s 应该抑制 diff 的输出,但是输出是:

$ git log --pretty=format:"%H" -s -L 70,70:./arch/x86/include/asm/irqflags.h

我使用的是 git 版本 2.10.2

最佳答案

Git 2.22(2019 年第 2 季度)会更加清晰。

git log -L<from>,<to>:<path>”和“-s”没有打补丁应有的输出。
这已得到纠正。

参见 commit 05314ef (2019 年 3 月 11 日),以及 commit 9f607cd (2019 年 3 月 7 日)作者:Jeff King ( peff ) .

line-log: detect unsupported formats

If you use "log -L" with an output format like "--raw" or "--stat", we'll silently ignore the format and just output the normal patch.
Let's detect and complain about this, which at least tells the user what's going on.

现在它会清楚地显示:

-L does not yet support diff formats besides -p and -s

在 Git 2.25(2020 年第一季度)中,文档增加了更多内容。

参见 commit 2be4586 , commit 2be4586 (2019 年 12 月 26 日)Philippe Blain ( phil-blain ) .

doc: log, gitk: document accepted line-log diff formats

Currently the line-log functionality (git log -L) only supportsdisplaying patch output (-p | --patch, its default behavior) and suppressing it(-s | --no-patch).
A check was added in the code to that effect in 05314ef(line-log: detect unsupported formats, 2019-03-10) but the documentation was not updated.

Explicitly mention:

  • that -L implies -p,that patch output can be suppressed using -s,
  • and that all other diff formats are not allowed.

和:

The line number, regex or offset parameters and in git log -L <start>,<end>:<file>, or the function name regex in git log -L :<funcname>:<file> must exist in the starting revision, or else the command exits with a fatal error.

所以,除了You can specify this option more than once ,你有:

Implies --patch.
Patch output can be suppressed using --no-patch, but other diff formats (namely --raw, --numstat, --shortstat, --dirstat, --summary, --name-only, --name-status, --check) are not currently implemented.


在 Git 2.30(2021 年第一季度)中,“ git log ( man )” 被记录为不采用路径规范,但这不是由命令行选项解析器强制执行的,它已被更正。

log: diagnose -L used with pathspec as an error

Heled-by: Jeff King

The -L option is documented to accept no pathspec, but the command line option parser has allowed the combination without checking so far.
Ensure that there is no pathspec when the -L option is in effect to fix this.

Incidentally, this change fixes another bug in the command line option parser, which has allowed the -L option used together with the --follow option.
Because the latter requires exactly one path given, but the former takes no pathspec, they become mutually incompatible automatically.
Because the -L option follows renames on its own, there is no reason to give --follow at the same time.

The new tests say they may fail with "-L and --follow being incompatible" instead of "-L and pathspec being incompatible".Currently, the expected failure can come only from the latter, but this is to future-proof them, in case we decide to add code to explicitly die on -L and --follow used together.
