Can GitHubcello be used against BitBucket?

2016-07-25 15:58 GMT+02:00 Sean Glazier <[hidden email]>:

Hi,

Thank you for all your help. Yes, windows is a pain. I am using Pharo 5. I would love to know how to get the ssh part working on Linux as well since the other team member is a Linux user and it is his first time using Smalltalk. I think he saw it in college but that was about it. I have shared the sort of things you can do in Smalltalk compared to other languages. However, The tool set can be a bit intimidating at times. There is a learning curve even for experienced small talkers coming from a different toolset. So when I set it up for myself I want to set his up as well.

I understand. I did the VW to Pharo a while back (around 2010 I think).

The linux setup is very simple, in fact. You generate a ssh key (with ssh-keygen), add the .pub part of the key into your profile on bitbucket, and git over ssh will work, including from Pharo.

But, as you point out below, if setting up the ssh key in windows causes that much pain, then adding https support is necessary. I'll try to find the time tonight to do that and tell you how to try it. I do have already bitbucket repos to try that.

Thierry

 

I think while it is insecure the https version is useful especially when tearing your hair out just trying to get source tree and bit bucket on speaking terms using ssh. I just spent the better part of a day and night trying to figure out why when both sides have the right key the server was still rejecting. It is windoze 10 of course. It should be a crime to sell that operating system! I have had more fun kicking cinder blocks with my feet. I mean that literally too, as I used to do that in the Okinawa Kempo classes. A broken toe is far more pleasant by comparison. 

By the time morning rolled around I was having fantasies of making Bill Gates condemned to rolling a boulder uphill only to have it to always fall down and he would have to repeat for eternity . :-) But I digress...

If you could point me in the right direction it would help.

Thank you in advance :-)

yes I was using the command generated by the source tree tool. The code generates a command line command and that can use https if you form the commands as I detailed. I also indicated where the master:master and related switches can be replaced with what most people use which is just --all. the class forming the command can be extended to parse out the username password from the url you set it up with provided you include it or it could be extra parameters provided and stored. This is so that when the push and pull commands put together the url can be formed and placed on the command line as well. GITI will take care of using https etc. it just needs the url with the username password on it so that the command line does not ask for a password and hangs the image because Pharo is waiting for a response and the command line is waiting for the password to be inputted and you have a deadlock as I detailed in the method.

Yes, I understand that.

 

The command line git command that worked for me was: 

git -C "C:\pharo5win\new-qline" -c diff.mnemonicprefix=false -c core.quotepath=false push https://sglazier456:MY_PASSWORD@.../sglazier456/new-qline.git --all

I am sure some of the other options are not really needed. As I indicated I used what source tree built as its command that it executed.

So with a git repository that needs a username password you can form the git push and pull commands as indicated.

to use ssh I did not see how that could be done from the command line on windows unless to were able to tell git to use ssh or the putty running on windows. Linux of course, is probably more straightforward to get working.

I know that there is a kind of special way to use ssh-agent in Windows, and get this to work.

I did not implement the https username and password support, because I was a bit unsure of writing in clear the username and password, and I didn't want to handle the terminal interaction to inject username and password into the git command upon request.

 

Right now the current version of the git remote repository is broken because it is using either old commands or an incorrect command. The push was sent to the command line as follows:

git -C "C:\pharo5win\new-qline" 

I'm sure there is a push in the command otherwise none of the git support would work; I use that code every day professionnally for as long as GitFileTree existed. The git command has been complete for the past few years, so it will stay this way unless harm is proven with the lack of certain options.

 

This as far as I know is not a proper push command because it needs the push keyword followed by at least I think by the --all .

I tried it from the windows command line and it worked for a repository that was not password protected. If it is, the command line will ask for the password and will not time out which deadlocks the push since pharo is waiting for the command to finish, which it cannot. So the image is locked until you give it a user interrupt to get the debugger.

I hope this helps in understanding what I ran into...

Windows is a hard platform for me to test on; I'll fetch a past discussion on ssh-agent on windows and I may create a branch for you to test. On which version of Pharo are you?

Thierry

Hi Sean,

I think the issue is simply that GitFileTree does not support https with authentification. You need to switch to ssh with keys.

Now, about the various options you add on the git push command line (diff.mnemonicprefix, core.quotepath), could you detail them? The seems to be unnecessary in the git development scenarios I've seen so far.

Also note that master:master may be wrong, because you could be switching to another branch.

I expect all those issues to be taken care of through the new tools in development for Pharo6.

some more information the git command that it runs is

git -C "C:\pharo5win\new-qline" 

This is run in the method MCFileTreeGitRemoteRepository>>runProcessWrapperGitCommand: anArrayOfStrings in: aDirectory.

It is stuck on the line:

 command waitForExit.

this wait for exit has no timeout to it and you wait forever. I found out on windows the user interrupt is alt .  Just like the Mac ;-)

I have no error in the error stream at all.

From the source tree tool the command should look more like this:

git -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags origin master:master

and then followed by the -C "C:\pharo5win\new-qline"

git -C "C:\pharo5win\new-qline" -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags origin master:master 

However doing this from a command line it asks for the users password like thus

C:\pharo5win\New-Qline>git -C "C:\pharo5win\new-qline" -c diff.mnemonicprefix=false -c core.quotepath=false push -v --tags origin master:master

Pushing to https://sglazier456@.../sglazier456/new-qline.git

Password for 'https://sglazier456@...':

to avoid the password prompt you can do this

git -C "C:\pharo5win\new-qline" -c diff.mnemonicprefix=false -c core.quotepath=false push https://username:password@.../file.git -v --tags origin master:master

you can also replace -v --tags origin master:master  with --all as well

in my case it would look like

git -C "C:\pharo5win\new-qline" -c diff.mnemonicprefix=false -c core.quotepath=false push https://sglazier456:MY_PASSWORD@.../sglazier456/new-qline.git -v --tags origin master:master

OR

git -C "C:\pharo5win\new-qline" -c diff.mnemonicprefix=false -c core.quotepath=false push https://sglazier456:MY_PASSWORD@.../sglazier456/new-qline.git -all

and that works with out the system waiting for a password.

I notice that there is a class that has the username password for bit bucket in the method MCGitBasedNetworkRepository >> siteUsername: username sitePassword: pass "MCBitbucketRepository siteUsername: '' sitePassword: ''" "MCGitHubRepository siteUsername: '' sitePassword: ''" self siteUsername: username; sitePassword: pass

I tried setting it up with the username and password in the url for the remote repository and no luck.

the class MCFileTreeGitRemoteRepository should override the getPull and gitPush so as to include the url with the site name and password or there might be a need for a different creation class for the bitbucket remote repositories. However it is a standrad git command to be able to include the username password in the url.

when one does a pull as well there is a hang as well for the same reasons.

I am not attempting to hack this at the moment because I can use source tree to do the commits and pushes and pulls. I do think though since we have those commands available on the remote repos and people can mark it private requiring a username password.

Also we should consider a repository configuration that specifys the SSH kaey and then run the command in the context of SSH. this would eliminate the username password issue and it is much more secure.

SO since you are more experienced than I in this area of the code, I should ask how should we go about fixing the issue. Also were should I report this issue as well?

running the command from a cmd line produced the following:

C:\pharo5win\New-Qline>git -C "C:\pharo5win\new-qline"

usage: git [--version] [--help] [-C <path>] [-c name=value]

           [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path]

           [-p|--paginate|--no-pager] [--no-replace-objects] [--bare]

           [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>]

           <command> [<args>]

The most commonly used git commands are:

   add        Add file contents to the index

   bisect     Find by binary search the change that introduced a bug

   branch     List, create, or delete branches

   checkout   Checkout a branch or paths to the working tree

   clone      Clone a repository into a new directory

   commit     Record changes to the repository

   diff       Show changes between commits, commit and working tree, etc

   fetch      Download objects and refs from another repository

   grep       Print lines matching a pattern

   init       Create an empty Git repository or reinitialize an existing one

   log        Show commit logs

   merge      Join two or more development histories together

   mv         Move or rename a file, a directory, or a symlink

   pull       Fetch from and integrate with another repository or a local branch

   push       Update remote refs along with associated objects

   rebase     Forward-port local commits to the updated upstream head

   reset      Reset current HEAD to the specified state

   rm         Remove files from the working tree and from the index

   show       Show various types of objects

   status     Show the working tree status

   tag        Create, list, delete or verify a tag object signed with GPG

So according to the help the command it self is formulated incorrectly.

runProcessWrapperGitCommand: anArrayOfStrings in: aDirectory

I created in Bitbucket a repository named New-QLine. I created aBaselinOfNewQLine which just has stubs. I created 2 Packages.

The code at this point has been committed successfully and now I want to Push it to the repository.  Once I hit the Push button the image freezes. I can press the x button on the main Pharo 5 window and I get the dialog do you want to quit with out saving.

I am assuming that the push is using a git command. I am not familiar with the Pharo 5 keyboard shortcuts. I tried control b along with some others in hopes of interrupting this process and bringing the image back and being able to debug. However, I was unsuccessful in that. I was thinking that I might need to supply a setting so the ssh session can use the privateKey I generated and then I can be verified and the command continues.

I am not sure what is going on yet. I thought I would ask to see if it is something simple I am missing.

If you need to I can email you my privateKey so you can try it against the same repository I am using.

Sean,

For GsDevKit_home[1] users on Windows, I recommend that users install GitHub DeskTop for Windows[2]. You get a bash shell installed that allows you to use git on windows in a reasonable environment ... I assume that at the bash shell level, you can work with local clones of bitbucket git repositories ...
