Git Directory Permissions Always 000

由 陌路散爱 提交于 2020-01-25 06:21:05
问题 By messing around with Git objects, I've found that the tree entries within a tree object always have these permissions. 040000 DirEntry hash The 04 means that it is a directory, but the permissions are 000. Does this mean that Git does not store tree permissions, or is that how Unix works? 回答1: Yeah. Git does not store permissions for tree objects, even though directories Unix filesystems do have them. For files, git only stores the executable bit (+x). All files are assumed to be readable

How can I recover HEAD^'S tree?

由 情到浓时终转凉″ 提交于 2020-01-01 10:15:10
问题 tl;dr: is it possible to recover HEAD^ 's tree if it is deleted and not pushed beforehand and if everything else is intact? I accidentally deleted part of my .git . I'm not entirely sure what's missing. Upon discovering that git push didn't work, I ran a git fsck : Checking object directories: 100% (256/256), done. Checking objects: 100% (1265/1265), done. broken link from commit f3419f630546ba02baf43f4ca760b02c0f4a0e6d to tree 29616dfefd2bff59b7fb3177e99b4a1efc7132fa broken link from commit

Get a list of changed files and their status for a specific Git commit

由 筅森魡賤 提交于 2019-12-23 10:25:36
问题 I use the following Git command git diff-tree --no-commit-id --name-only -r <SHA> to get a list of changed files. Unfortunately, the list doesn't specify the type of change for each file: added, modified or deleted ... etc How may I display a list of changes [type of change, file name] in a given SHA of a specific commit. 回答1: Use --name-status instead of --name-only git diff-tree --no-commit-id --name-status -r <SHA> This will show the filename with a status letter of (extracted from man):

Expand git's autocomplete feature to plumbing commands

由 大憨熊 提交于 2019-12-10 10:36:43
问题 As a follow up to this question, I asked myself if it would be possible to tell git to provide it's autocomplete feature (branches etc.) for further commands, in particular plumbing commands like update-ref . Although update-ref provides more flexibility than branch -f , it's quite a hassle to use since you always have to type the full reference name. Which in turn doesn't make me want to use it. Any ideas on this? 回答1: It is possible to enable the plumbing commands but you will need to

Git clone bare repo without blobs

由 我只是一个虾纸丫 提交于 2019-12-01 11:03:54
On my git repository, I use an algorithm to assign every commit one or more unique version numbers, based on branch names and tags. I want to use this mechanism with another large repository, that I would like to clone without transferring any files. A bare clone helps me to get rid of the working copy of the blobs, but it still downloads them from the server. A shallow clone with --depth 1 skips most blobs, but also skips downloading the metadata for all commits except one. Is there something like git fast-export --no-data which I can use on the client-side to get the graph information

git scripting: How to list all git branches containing a commit

由 老子叫甜甜 提交于 2019-11-28 12:20:45
I can list all branches containing a certain commit using git branch --list --contains just fine. But as explained in the related question on how to list all branches , this is a porcelain command that should not be used in scripts. The latter question suggests to use the plumbing command git for-each-ref , but that does not support --contains . What is the correct plumbing interface to list all branches that contain a certain commit. jub0bs One possible solution using the plumbing commands git-for-each-ref and git merge-base (the latter suggested by Joachim himself): #!/bin/sh # git
