kandi X-RAY | scm Summary
This is a c++ library supporting statechart (in scxml format) originated by David Harel. Features like hierarchical states, parallel states, and history are ready for you to command. You won't find another one as easy and flexible to use as SCM. Just read this simple example. Build this and run it, you should see: """ come to exist we are going to... *** Hello, World! ***. start living start eating start moving stop eating stop moving no longer live end """.

QUESTION
I know that --quit does not change your HEAD pointer, so any commits made successfully during a rebase or cherrypick are still there.
But what I'm unsure of is, in case a conflict happened during a cherry-pick or a rebase, whether using --quit clear the changes brought about by the conflict, such as the successfully added changes, the conflict markers in the working directory, the multiple versions in the index etc ?
The git rebase documentation has the following:
--quit Abort the rebase operation but HEAD is not reset back to the original branch. The index and working tree are also left unchanged as a result.
the cherry-pick documentation is less clear about the effects on the index and work tree:
--quit Forget about the current operation in progress. Can be used to clear the sequencer state after a failed cherry-pick or revert.
But this otherwise excellent answer in SO has the following:
But if you choose --quit, Git terminates the rebase without moving HEAD, so that you wind up with:
but a clean index and work-tree. So you don't have to be clever enough to attach a branch name before the --quit.
So which is it ? I know that in a merge --quit will not clear the mess that a merge conflict makes in your index and work tree, it just abandons the merge head state. is it different in case of a cherry pick or a rebase ?
...ANSWER
Answered 2022-Apr-14 at 23:00It really depends on the state you had at the time you issue the --quit
: Git just stops here. I'll update the other answer to indicate that you can then git reset --hard
to make it "clean" if you want, or leave it "dirty" if you want.

currently, I try to build a spring boot application and make releases with Azure Pipelines and maven-release-plugin.
My Azure Pipeline YAML Looks like this:
...ANSWER
Answered 2022-Feb-09 at 08:01Ok, I found a solution for me that involves using the Azure DevOps Git SSH URL and not the HTTPS.
First of all, I created a SSH Key according to this Use SSH key authentication or choose your Git providers tutorial.
Once you have your SSH private and public key, you need to install the SSH Key into your YAML pipeline. See Install SSH Key task.
QUESTION
Some years ago, Mercurial | TortoiseHG could exchange data bidirectionally easy with at least 2 Big Brothers:
- Subversion, using HGSubversion
- Git, using HG-Git
Current (6.0 versions of family) state - the ordinary users have none:
- hg-subversion is broken (extension can't be loaded), bundled with THG (Mercurial ???) extension not updated since 2019
hgsubversion: 6a6ce9d9da35 2019-04-19
(extraction from myTortoiseHg\extension-versions.txt
), external SVN-bindings exist only for Python 2.7 (while py3-movement inside Mercurial is live and active) - hg-git got some big troubles, starting from THG 4.9 (manual patching of library.zip was required), on 6 version the situation has gotten better (no patching), but still unsatisfactory for the common user - installing Python 2.7 (for single-user) and using
pip
isn't The Right Way (tm)
Are there any comments, additions, clarifications, recommendations on how to do it (if what I am doing is wrong)?
Addition after some testing: special verson tortoisehg-6.0hggit-x64.msi from Matt Harbison at least allow using hg-git with ssh-transport (not http yet) and can be recommended for every-day usage by ordinary user.
...ANSWER
Answered 2022-Mar-04 at 18:12So, as a current maintainer of hg-git and former contributor to hgsubversion, I think I can provide some context here.
Regarding hgsubversion, the short answer that it is either dead or — at best — extremely dormant. Personally, I have not interacted with a Subversion repository in years, and that's a common experience. No-one has been sufficiently motivated to fix bugs, keep it working, and — last, but not least — make it work with Python 3.
For hg-git, a period of semi-dormant state meant that the TortoiseHg maintainers stopped bundling it. We now keep up with Mercurial releases, and I've requested that they reverse that decision. I believe they bundle Dulwich, but as I don't use Windows, I can't say for sure. That said, it's quite reasonable to want to use hg-git with TortoiseHg, and if you run into any specific issues, I'd suggest you file a bug with them — or perhaps add a comment to the bug I linked earlier.
Generally speaking, you should be able to use 0.10.x version of hg-git with most versions of TortoiseHg, as I believe they bundle Dulwich. In that case, enabling the extension should be as simple as:

This worked fine for me be building under Java 8. Now under Java 17.01 I get this when I do mvn deploy.
mvn install works fine. I tried 3.6.3 and 3.8.4 and updated (I think) all my plugins to the newest versions.
Any ideas?

This is actually a known bug, which is now open for quite a while: OSSRH-66257. There are two known workarounds:
1. Open ModulesAs a workaround, use --add-opens

QUESTION
In the pipeline SCM configuration of Jenkins job builder, we have two options- lightweight checkout and shallow clone. What is the difference between these options and when do we use each option?
...ANSWER
Answered 2022-Feb-11 at 09:34From the documentation:
Shallow clone.
Perform a shallow clone, so that git will not download the history of the project, saving time and disk space when you just want to access the latest version of a repository.
Lightweight checkout.
If selected, try to obtain the Pipeline script contents directly from the SCM without performing a full checkout. The advantage of this mode is its efficiency; however, you will not get any changelogs or polling based on the SCM. (If you use checkout scm during the build, this will populate the changelog and initialize polling.) Also build parameters will not be substituted into SCM configuration in this mode. Only selected SCM plugins support this mode.
To sum up:
- Shallow Clone is the Git feature that lets you pull down just the latest commits, not the entire repo history. So if your project has years of history, or history from thousands of commits, you can select a particular depth to pull.
- Lightweight checkout is a Jenkins capability that enables to pull a specific file from the repo, as opposed to the entire repo. So it is useful for example when fetching the Jenkinsfile from a repo because you you need only the specific file and Don't care about other SCM information.
QUESTION
I'm upgrading from JDK 8 to JDK 17 and I'm trying to compile with mvn clean install -X -DskipTests
and there's no information about the error.
Btw, I'm updating the dependencies and after that I compile to see if has errors. I need to update some dependencies such as Spring, Hibernate etc. I already updated Lombok.
I added the -X or -e option but I got the same result.
What can I do to get more information about the error? The log shows that it was loading hibernate-jpa-2.1-api before failed... so that means the problem is in this dependency?
...ANSWER
Answered 2021-Oct-19 at 20:28This failure is likely due to an issue between java 17 and older lombok versions. Building with java 17.0.1, lombok 1.18.20 and maven 3.8.1 caused a vague "Compilation failure" for me as well. I upgraded to maven 3.8.3 which also failed but provided this detail on the failure:
java.lang.NullPointerException: Cannot read field "bindingsWhenTrue" because "currentBindings" is null
Searching for this failure message I found this issue on stackoverflow leading me to a bug in lombok. I upgraded to lombok 1.18.22 and that fixed the compilation failure for a successful build.
QUESTION
The git-scm website says that it's at github under the download section.
However Wikipedia says it's at git.kernel.org. There's also corresponding clone links in that site.
...ANSWER
Answered 2022-Jan-05 at 18:23https://git.kernel.org is correct, specifically https://git.kernel.org/pub/scm/git/git.git/.
https://github.com/git/git has "About" text that indicates it is a mirror:
Git Source Code Mirror - This is a publish-only repository but pull requests can be turned into patches to the mailing list via GitGitGadget (https://gitgitgadget.github.io/).
git-scm.com
seems to be only semi-official: It's linked from the source tree's README but per the About this site link at the bottom, git-scm is an open-source third-party piece of documentation that became the Pro Git book (advertised in the left column). Since the official repo is based on cgit
and is relatively minimal in its UI, I imagine GitHub and git-scm are more welcoming to newcomers and thus more popular.
QUESTION
This is a very beginner question on Git. I am following along the book here and website here with respect to branching and merging.
I have a readme file on github that I pull onto my local machine where i create a branch, update the readme file and attempt to merge it back to the main/origin. I cant seem to get the last step right and i would appreciate any pointers.
...ANSWER
Answered 2021-Dec-15 at 13:23You want to go back from branch issue-1
to master
or main
.
You should do git checkout master
or git checkout main
instead of git checkout origin
.
origin
is the name of the remote (which is GitHub in your case). Not the name of a branch.
QUESTION
When publishing an ASP.NET Core 6 web application with C# 10's enabled to an Azure App Service from a Visual Studio 2022 publishing profile, the publishing build fails due to missing
using
statements.
C# 10 introduces the new implicit usings feature, where certain using
directives are treated as global using
directives based on the SDK. This can be enabled with the following csproj
configuration:
ANSWER
Answered 2021-Nov-10 at 22:58First of all, it appears that this was a false alarm. I apparently neglected to finish rebooting my workstation after installing the release version of Visual Studio 2022. After restarting, I am now able to publish with full support for implicit usings. Whoops.
That said, this does provide a good opportunity to offer some insight into what I discovered after the fact, which may help future readers with similar types of issues—and certainly helped me better understand the integration between the various command-line tools.
Command-Line ArgumentsNotably, there doesn't appear to be any command-line parameters for handling implicit usings built into any of the following tools:
- .NET 6.0 SDK (
dotnet.exe
) - Visual C# compiler (
csc.exe
) - Microsoft Build Engine (
msbuild.exe
)
Instead, this is handled via the Microsoft Build Engine (msbuild.exe
) when working off of a C# project file (*.csproj
), at which point it generates the following intermediate file at:
QUESTION
One my colleagues accidentally ran git merge -
and it seemed to merge the branch they were last on. Fascinating. git describe -
errors out fatal: Not a valid object name -
. git symbolic-ref --short -
also errors out with fatal: ref - is not a symbolic ref
.
It's obviously(?) impossible to search for this. Where is this documented, is this merge specific, if not where else could it be used?
Edit: our principal sw engineer pointed out https://git-scm.com/docs/git-checkout You may also specify - which is synonymous to @{-1}
so I guess the same happens to git merge
but a) it's not documented under git merge
b) git describe
or git log
doesn't work with -
while both work with @{-1}
c) it's still not clear where else could it be used especially if it's undocumented.
ANSWER
Answered 2021-Dec-11 at 01:25The dash syntax to represent @{-1}
is implemented in some commands and not others, and its design comes from cd
, which typically supports a similar feature (switching to the last directory).
It's known upstream that it's not implemented in all commands, and the threshold for implementing it is roughly, "Is it useful in this case to refer to the immediately previous branch in this context?" Clearly it's useful in checkout, switch, and restore, but nobody thought it was useful in log, so it wasn't implemented. If you can make a compelling argument for implementing it, patches would be welcome. The Git list has received patches for this in the past.
The reason it doesn't work everywhere is because it's implemented on a command-by-command basis instead of in the revision parsing machinery, like @{-1}
is. Things implemented in the revision parsing machinery (documented in the gitrevisions(7)
manual page) will be available everywhere.
