QUESTION
History of all git commands issued from repo's initialization
Asked 2022-Mar-27 at 10:31I have the following use case:
On my local computer, I had the following structure of files/folders outside of any version control system, including git.
1ProjectFolder
2 ---Folder1
3 ----File1.txt
4 ----Folder2
5 ----File2.txt
6 ----100s of other files/folders
7In preparation for version control, I first ran git init in this folder.
This gave me:
1ProjectFolder
2 ---Folder1
3 ----File1.txt
4 ----Folder2
5 ----File2.txt
6 ----100s of other files/folders
7ProjectFolder
8 ---.git
9 ---Folder1
10 ----File1.txt
11 ----Folder2
12 ----File2.txt
13 ----100s of other files/folders
14I then went to github and created a repository, say:
https://github.com/Tryer/ProjectFolder.git
After this, from the command line on my machine, I issued:
git remote add origin https://github.com/Tryer/ProjectFolder.git
I did not want to add Folder2 and its contents to the commit. I only wanted Folder1 and its contents to be committed.
I, by mistake, did not created a proper .gitignore file leading to staging of some files from Folder2 when I then issued git add .
I do not now remember exactly whether I issued git rm -f <files from Folder2> or git rm --cached <files from Folder2> to unstage the unneeded files from Folder2. The former would have forced deleted the files from Folder2 from both the staging area as well as my working tree (something I did not intend/want). The latter would have only unstaged the files but left them in my working tree (something that is precisely what I would have wanted.)
The number of files under Folder2 are rather large and a due diligence check on Folder2's contents manually on my machine seems to reveal nothing amiss in terms of missing files from my working tree.
Yet, just to be absolutely sure, is there a way to list all of the git commands ever issued under a repository from the beginning of time? Note that I am not asking for a history of commands I have issued from the terminal command line. This would be available in a powershell history or bash shell history.
A previous question of exactly this issue is available here. However, the question is about 10 years old and the highest voted answer there suggests to use git reflog. However, that seems to give history in terms of commits. I am looking more for the exact git commands that I have executed.
ANSWER
Answered 2022-Mar-27 at 10:31No, it's not possible with Git. Git does not keep track of the commands executed in a repository.
Your best bet is your shell's command history.
QUESTION
composer remove (uninstall) all installed packages (composer install rollback)
Asked 2022-Mar-16 at 15:36I have a project with the composer.lock file.
I installed packages with the command:
1composer install
2Now I would like to rollback that composer install command to the state as it was before running it.
How to remove all packages without affecting composer.lock file?
Is there any single composer command to do that?
I tried:
1composer install
2composer remove *
3but I got:
[UnexpectedValueException]
"LICENSE" is not a valid alias.
I tried:
1composer install
2composer remove *
3composer remove */*
4But then I get bunch of print like:
bin/console is not required in your composer.json and has not been removed
Package "bin/console" listed for update is not locked.
Why composer remove * did not work at all? AFAIK the package name as VendorName/PackageName is a common convention for Packagist but not a must (if you use private repos) so how one would be able to remove all packages named IdontHaveAnySlash etc. at once?
I may use someting similar to:
1composer install
2composer remove *
3composer remove */*
4for package in $(composer show | awk '{print $1}'); do composer remove --no-interaction --dev --no-install "$package"; done
5But that is not a simple and single composer command.
Also composer often complains about a package being a part (dependency) of another one so composer does not uninstall it.
Removal failed, doctrine/annotations is still present, it may be required by another package. See
composer why doctrine/annotations.
As my intention is to rollback to the state that did not have any package installed but only files: composer.lock and potentially composer.json I really don't care about any dependencies, packages versions, downloading repositories' urls etc.
I just want to have a project without any installed dependencies as it was before.
Is there any single composer command to do that?
My:
1composer install
2composer remove *
3composer remove */*
4for package in $(composer show | awk '{print $1}'); do composer remove --no-interaction --dev --no-install "$package"; done
5composer --version
6is:
version 2.2.7 2022-02-25 11:12:27
Following yivi answer I created a simple test to verify:
1composer install
2composer remove *
3composer remove */*
4for package in $(composer show | awk '{print $1}'); do composer remove --no-interaction --dev --no-install "$package"; done
5composer --version
6mkdir -p /tmp/composer-install
7cd /tmp/composer-install

9curl -o composer.json https://raw.githubusercontent.com/composer/composer/18246212db7103d0a2688febcc336f77183275ee/composer.json
10
11curl -o composer.lock https://raw.githubusercontent.com/composer/composer/d955458f271edb4fcc055a394f90a60a8328a2a8/composer.lock
12
13sha1sum composer.json > composer.json.sha1
14sha1sum composer.lock > composer.lock.sha1
15
16composer install
17
18sha1sum -c composer.json.sha1
19sha1sum -c composer.lock.sha1
20
21that outputs:
composer.json: OK
composer.lock: OK
So both composer.json and composer.lock are not affected by composer install so the only one thing to achieve the rollback (uninstall) of the composer install is to remove the vendor directory
1composer install
2composer remove *
3composer remove */*
4for package in $(composer show | awk '{print $1}'); do composer remove --no-interaction --dev --no-install "$package"; done
5composer --version
6mkdir -p /tmp/composer-install
7cd /tmp/composer-install
8
9curl -o composer.json https://raw.githubusercontent.com/composer/composer/18246212db7103d0a2688febcc336f77183275ee/composer.json

11curl -o composer.lock https://raw.githubusercontent.com/composer/composer/d955458f271edb4fcc055a394f90a60a8328a2a8/composer.lock

14sha1sum composer.lock > composer.lock.sha1
15
16composer install
17
18sha1sum -c composer.json.sha1
19sha1sum -c composer.lock.sha1
20
21rm -rf vendor
22However as yivi mentioned:
If some other plugin (e.g Symfony Flex) makes changes to your existing files during the process, you'd better have the project on top of a version control system, in which case reverting is managed by VCS, not of composer.
I did not test against that case.

22rm -rf vendor
23In any case, install should not make any changes to a lockfile, so there shouldn't be anything to "revert" from an install but deleting the installed files.
If the lockfile does not originally exist, then it will be created.
If some other plugin (e.g Symfony Flex) makes changes to your existing files during the process, you'd better have the project on top of a version control system, in which case reverting is managed by VCS, not of composer.
As my intention is to rollback to the state that did not have any package installed but only files: composer.lock and potentially composer.json
For you to be able to run composer install at all, you need at the very least composer.json to exist. install reads from the lockfile (composer.lock), but requires the JSON configuration file to exist as well. If the lockfile does not exist, update will be run instead and the lockfile will be created.
I tried
composer remove
remove is the opposite from require. It removes packages from composer.json, as require adds them. Not the opposite of install. There is no opposite of install, as it does not make much conceptual sense. If one needs to delete the installed project... one can always do so.

QUESTION
First time Git user, Push to remote repository takes forever
Asked 2021-Nov-18 at 15:39Win 10, using Git bash. Git version 2.32.0.windows.1. Researched similar/same topics, they didn't help.
I'm a new user of Git, trying to learn how to use it, never used version control systems before, and I don't have anyone fleshy to ask or show me.
I follow the tutorial and even understand what's going on so far, but the push to the remote repository takes forever and does nothing. Everything up to that point worked.
Tutorial I'm using: YouTube Link with timestamp
What I successfully managed to do: created my first local repo, created dummy test file (took a random script for PCB CAD program with a bit of text, doesn't matter I guess), learned to create a branch and commit stuff to local branches. My head is about to explode, but it works, and I understand it so far. But pushing to remote repo hangs without giving any hint or clue.
I did a bit of research and found this topic here on StackOverflow: link
I added --verbose to the push command, so now it looks like this:
1$ git push -u --verbose origin main
2Pushing to https://github.com/ellectroid/test_public_repository.git
3And then it hangs forever. Highly uninformative.
Also, in the stackoverflow post in the link above someone talks about protocols. I tried http and https. No difference.
Then someone (goes by Azeez) said to ensure I'm authenticated on GitHub. Well, I'm logged in in the browser, although I don't understand how that is connected, but I'm logged in. And then in the same post they write some quote:
Select an authentication method for 'https://github.com/':
- Web browser (default)
- Personal access token option (enter for default):
I have zero clue what this is, I was never asked to authenticate anything in the bash, and I have no clue how to do it. The tutorial doesn't do it and everything works there out of the box.
I'm a 100% Git and GitHub noob, registered an account like half a year ago, but today is my first day of actually trying to use it, and I immediately get this in the face without any clue as to why and what to do, so I would appreciate if your reply explained what to do in detail. I just want to be able to push what I have in my local repo to the GitHub.
I'm not using any proxy or anything, if that matters.
If you need more information from me, please tell me what information and where do I get that information. As I said, I don't know anything about Git yet, but very much want to.
P.S. I'm aware about master and main branch names and accounted for it.
UPDATE
On the next day when I tried to push, a Git GUI popped up with openSSH in window title asking me for GitHub username. I entered my username, which was for some reason all with asterisks (never seen login written with asterisks), I entered my GitHub username "ellectroid" and got "Application error" window with text "Error: error writing "stdout": broken pipe". I opened detailed error message, it says:
1$ git push -u --verbose origin main
2Pushing to https://github.com/ellectroid/test_public_repository.git

19UPDATE 2 After extensive googling I found what person in the comments was talking about. Turns out there is a file with the name "config" without extension in the hidden folder .git in my local repo (was it difficult to explain like this? Sorry, I said I'm noob, you could word it friendlier for noobs), so here are the contents of this "config" file:

32I tried origin2 to try with http instead of https. I still get error when authenticating on github in Git GUI OpenSSH window, where I enter my login with asterisks ("ellectroid") and it spews out broken pipe error like above.
UPDATE 3
Thanks to @VonC, who invited me to the chat, we figured out all I had to do is to push not from the Git Bash, but from Windows CMD. Then, when I push, it immediately prompted me to use Personal Access Token, which I already created. Also, I did it with admin rights. Later on I changed environment variable PATH to include path to bash, so I can just write "bash" in CMD and get fancy colors and stuff. Case closed.
ANSWER
Answered 2021-Nov-18 at 15:08On Windows, try and push from the command-line (not from a GUI) to test if that would be working.
Make sure that, in a simple CMD:
git config credential.helperdoes returnmanager-core- git ls-remote https://github.com// triggers a popup where you can enter your GitHub user account name and your PAT (Personal Access Token that you need to create first)
Then try and git push from within your local repository folder.
From the discussion, this started to work with:
C:\Program Files\Git\bin, so you need to add it to the system PATH (it is wherebash.exeis)- a CMD opened as Administrator
QUESTION
Should I be adding the Django migration files in the .dockerignore /.gitignore file?
Asked 2021-Nov-17 at 16:12This is probably a duplicate of this question.
My question is how should I approach this when working in a docker environment so for my project I have a docker-compose.yml and docker-compose-deploy.yml for my production environment and obviously migration files are generated only in the docker images and aren't included in my version control system.
How should I approach this? should I stop using Docker as my development environment and go for something like virtual environments or even machines?
ANSWER
Answered 2021-Nov-17 at 16:12No. The migration files are there so you can update your database without destroying it and rebuilding it from scratch (or doing the sql update statements by hand).
So you definitely want to track them in your version control.
During development, a classic scenario would be
- write code
- make migrations
- apply migrations on your dev database
- test the changes locally
- check in and push the commit to your production server
- execute the migrations (so only do
python manage.py migrate) in production
Edit: I forgot to answer your docker question. Usually you put your source code in a volume outside the container, that you then mount into the container. So you can do docker development like this. That way the migration files and up in your codebase and you can track it.
QUESTION
How can I find all common sub strings using Rust , Python, javascript?
Asked 2021-Nov-04 at 02:16Git is an awesome version control system, I want learn git by writing my own version control system. The first step I have to do is implement a string diff tool. I've read this blog and this paper. In order to get the diff of two strings, I need to locate the common part. Hence, I came into the problem: How can I find all common sub strings of two strings?
This is first part of my problem：The algorithm problem.
This is the algorithm I am using:
Algorithm Problem【Problem】Find all common sub strings of string1 and string2.
【Solution】
- compare all sub string of string1 with string2 then gather matches into answer.
- compare all sub string of string2 with string1 then gather matches into answer.
This algorithm is O(N^2) time complex.
The language ProblemTo proof my thought, I can easily implement it with Python:
1def commonSubstringFinder(string1, string2):
2 answer=[]
3 len1, len2 = len(string1), len(string2)
4 match = ""
5 x,y = 0,0
6 for i in range(len2):
7 for j in range(len1):
8 if ( i+j < len2) and (string1[j] == string2[i+j]):
9 if len(match)==0:
10 x,y=i+j,j
11 match += string1[j]
12 else:
13 if len(match)>0:
14 answer.append(((x,y), match))
15 match=""
16
17 for i in range(1,len1):
18 for j in range(len2):
19 if (i+j<len1 and string1[i+j] == string2[j] ):
20 if len(match)==0:
21 x,y=j,i+j
22 match += string2[j]
23 else:
24 if len(match)>0:
25 answer.append(((x,y), match))
26 match=""
27
28 return answer
29
30print(commonSubstringFinder("apkleses", "appleses"))
31print(commonSubstringFinder("cappleses", "caplekses"))
32
33# [((0, 0), 'ap'), ((3, 3), 'leses'), ((2, 1), 'p'), ((6, 4), 'es'), ((4, 6), 'es')]
34# [((0, 0), 'cap'), ((6, 6), 'ses'), ((7, 5), 'es'), ((2, 3), 'ple'), ((6, 8), 's'), ((4, 7), 'e')]
35
36However, It's really hard for me to migrate this algrithom by using Rust Programming language. The problem is Rust programming language always uses iter(say string1.chars()) to get chars instead of index.
Any 🦀 can help me？
ConclusionI found an interesting thing when I solve this problem: How Do biologists find the common part of two DNA or RNA?

QUESTION
Why does the Version Control System Git stage files first, instead of committing them directly?
Asked 2021-Aug-12 at 10:03Why does the Version Control System Git stage files first, instead of committing them directly? I mean why we can't just commit files directly instead of staging them firstly then commit them?
ANSWER
Answered 2021-Aug-12 at 09:58Instead of committing all of the changes you've made since the last commit, the stage lets you group related changes into highly focused snapshots before actually committing it to the project history. This means you can make all sorts of edits to unrelated files, then go back and split them up into logical commits by adding related changes to the stage and commit them piece-by-piece. As in any revision control system, it’s important to create atomic commits so that it’s easy to track down bugs and revert changes with minimal impact on the rest of the project.
