QProcess - Git

[RegMe]

Hi everyone,

I'm trying to use QProcess with Git, I want to clone my repository to create a local copy on my computer using git clone

Typing this line in Terminal

git clone ssh://user@host:port/Template.git

git clone ssh://user@host:port/Template.git

To copy to clipboard, switch view to plain text mode 

works well

But in Qt, I still have a problem

QProcess process;
    process.start("git clone ssh://user@host:port/Template.git", QStringList());
 
    if (!process.waitForStarted()) {
        qDebug() << "Error : " << process.errorString();
        return 1;
    }
//process.waitForFinished(-1); // will wait forever until finished

QProcess process;
    process.start("git clone ssh://user@host:port/Template.git", QStringList());
    
    if (!process.waitForStarted()) {
        qDebug() << "Error : " << process.errorString();
        return 1;
    }
//process.waitForFinished(-1); // will wait forever until finished

To copy to clipboard, switch view to plain text mode 

Error console : Error : "No such file or directory"

Any help is very appreciated

Hmmm, how many times has this QProcess question been asked and answered on this forum? From the QProcess::start() docs:

void QProcess::start(const QString & program, const QStringList & arguments, OpenMode mode = ReadWrite)

Starts the given program in a new process, passing the command line arguments in arguments.

In your case this means:

QProcess process;
QStringList arguments;
arguments << "clone" << "ssh://user@host:port/Template.git";
process.start( "git", arguments );

QProcess process;
QStringList arguments;
arguments << "clone" << "ssh://user@host:port/Template.git";
process.start( "git", arguments );

To copy to clipboard, switch view to plain text mode 

Assuming of course that the git program is on your system's executable search path and that you have permission to execute it.

You are using this version of method QProcess:start : void QProcess::start(const QString & program, const QStringList & arguments, OpenMode mode = ReadWrite). QProcess is looking for file with name

"git clone ssh://user@host:port/Template.git"

"git clone ssh://user@host:port/Template.git"

To copy to clipboard, switch view to plain text mode 

Of course it fails. Try this :

process.start("git clone ssh://user@host:port/Template.git");

process.start("git clone ssh://user@host:port/Template.git");

To copy to clipboard, switch view to plain text mode 

or this

QStringList params;
params << "clone" << "ssh://user@host:port/Template.git";
process.start("git", params);

QStringList params;
params << "clone" << "ssh://user@host:port/Template.git";
process.start("git", params);

To copy to clipboard, switch view to plain text mode 

P.S. d_stranz was faster

[RegMe]

Thank you for your ansewers;

I have already tried the method 1:

process.start("git clone ssh://user@host:port/Template.git");

process.start("git clone ssh://user@host:port/Template.git");

To copy to clipboard, switch view to plain text mode 

// fails

I'll try tomorrow the 2nd

[Lesiok]

Remember what d_stranz wrote : Assuming of course that the git program is on your system's executable search path and that you have permission to execute it.

[RegMe]

The same problem for the 2nd method :

QProcess process;
QStringList arguments;
arguments << "clone" << "ssh://user@host:port/Template.git";
process.start( "git", arguments );

QProcess process;
QStringList arguments;
arguments << "clone" << "ssh://user@host:port/Template.git";
process.start( "git", arguments );

To copy to clipboard, switch view to plain text mode 

process.start("git clone ssh://user@host:port/Template.git");
 
    if (!process.waitForStarted()) {
        qDebug() << "Error : " << process.errorString();
        return 1;
    }
    qDebug() << "No Error ";
 
    process.waitForFinished(-1); // will wait forever until finished

process.start("git clone ssh://user@host:port/Template.git");

    if (!process.waitForStarted()) {
        qDebug() << "Error : " << process.errorString();
        return 1;
    }
    qDebug() << "No Error ";
   
    process.waitForFinished(-1); // will wait forever until finished

To copy to clipboard, switch view to plain text mode 

Console output : No Error ===> Process starts OK ??

I have used QProcess with Gerrit without problems. exmple :

process.start("ssh -p port user@host gerrit create-project test")

process.start("ssh -p port user@host gerrit create-project test")

To copy to clipboard, switch view to plain text mode 

===> Creates project in Gerrit OK

Assuming of course that the git program is on your system's executable search path and that you have permission to execute it

How can I be sure of it ??
If Gerrit works without pbs ===> Git also works also ??

[Lesiok]

Simple : open system command line and type git<Enter>.

[RegMe]

Yes, I have

I Have already used git clone on system command line whitout problem

Qprocess with Gerrit works well

QProcess with Git fails

projectClone = "git clone ssh://user@host:port/Template.git";
    process.start(projectClone);
 
    if (!process.waitForStarted()) {
        qDebug() << "Error : " << process.errorString();
        return 1;
    }
    qDebug() << "No Error" ;
 
    if(process.waitForFinished())
    {
        qDebug() << "Error Waiting : " << process.errorString();
        return 1;
    }

projectClone = "git clone ssh://user@host:port/Template.git";
    process.start(projectClone);

    if (!process.waitForStarted()) {
        qDebug() << "Error : " << process.errorString();
        return 1;
    }
    qDebug() << "No Error" ;

    if(process.waitForFinished())
    {
        qDebug() << "Error Waiting : " << process.errorString();
        return 1;
    }

To copy to clipboard, switch view to plain text mode 

Console output :
No Error
Error Waiting: "Unknown error"

[Lesiok]

Is exactly the same command working in command line ?
Do it need some sort of interaction ?

[RegMe]

Yes the same :

git clone ssh://user@host:port/Template.git

git clone ssh://user@host:port/Template.git

To copy to clipboard, switch view to plain text mode

No, just the previous command

I have no idea

[RegMe]

Hii,

There is no error in the programm

projectClone = "git clone ssh://user@host:port/Template.git";
    process.start(projectClone);
 
    if (!process.waitForStarted()) {
        qDebug() << "Error : " << process.errorString();
        return 1;
    }
 
    if(!process.waitForFinished())
    {
        qDebug() << "Error Waiting : " << process.errorString();
        return 1;
    }

projectClone = "git clone ssh://user@host:port/Template.git";
    process.start(projectClone);
 
    if (!process.waitForStarted()) {
        qDebug() << "Error : " << process.errorString();
        return 1;
    }
 
    if(!process.waitForFinished())
    {
        qDebug() << "Error Waiting : " << process.errorString();
        return 1;
    }

To copy to clipboard, switch view to plain text mode 

But, I don't see the project in my directory
With cmd line, I see the project

[Lesiok]

Before process.start() put in code :

qDebug() << QDir::current();

qDebug() << QDir::current();

Thanks it works
