Rocket® Open-Source Languages and Tools for z/OS®

The version of a distribution is often not enough for uniquely identifying it for purposes of knowing whether or not you have the most up-to-date code. Sometimes, for the same tool version, Rocket will make available for download multiple iterations each with a different build number. When requesting support for a language or tool from Rocket be sure to include the name, version, and build number. The build number is part of the original distribution file you downloaded from Rocket. Also, in the unpacked distribution you will find a VERSION.ZOS file that contains this information within this sub-folder: share/doc/<toolName>/<version>  (e.g. share/doc/bash/4.3) It is best to keep this file so you can uniquely identify your tool version.------------------------------Peter FandelRocket Software------------------------------

Before installing your distribution you need to unpack it. All z/OpenSource languages and tools are delivered as gzip tar files (e.g. automake-1.10_b0001.160204.tar.gz) with the exception of gzip which is delivered as a simple tar file (e.g. gzip-1.6-edc_b0002.160204.tar). If you do not already have gzip on your system you will need to start by downloading and installing gzip and to unpack the gzip distribution you need only issue a standard tar extraction command. To unpack all other z/OpenSource languages and tools from Rocket enter the following commands using your own destination directory in place of /rsusr/rocket: gunzip tool.tar.gz tar -C /rsusr/rocket -xoUXf tool.tar For example, if unpacking automake-1.10_b0001.160204.tar.gz, issue the commands: gunzip automake-1.10_b0001.160204.tar.gz tar -C /rsusr/rocket -xoUXf automake-1.10_b0001.160204.tar Each Rocket open source distribution comes with tool-specific installation instructions (README.ZOS) and a version information file (VE

All of the Rocket z/OS ports of open source languages and tools are available for download from the Rocket Community website downloads page. Log in to the Rocket Community here: https://my.rocketsoftware.com/RocketCommunity/RCLogin If you do not have an account, you can request one here at no cost. All downloads are meant to be unpacked on z/OS. However, most people first download to a PC and then transfer to z/OS (e.g. via SFTP) for unpacking. Be sure to use binary mode when transferring!------------------------------Peter FandelRocket Software------------------------------

Hi I am trying to use jenkins job to clone a repository from Gitlab to z/OS USS. Manually via Git commands am able to clone to z/OS. But when i try to clone via Jenkins am getting below error.

Hi, we have python 3 installed and working correctly when the $PATH and $LIBPATH are set. However, as I want to use python for running Ansible against the LPAR .bashrc and .profile can’t be used. Ansible uses SSH remote commands to work, the equiv of:- ssh winmvs2c.hursley.ibm.com ‘python --version’ How can I update USS so that python 3 is available for all users without relying on .bashrc or .profile and will work with non-interactive SSH sessions?

I just installed the findutils package on my z/OS 2.3 system. When I do a “man find”, I get the following type of output (from OMVS) with codepage of IBM-1047. It’s not formatted correctly. Am I doing something wrong? Does anyone else see this? I have the rocket dir first in my MANPATH, PATH, etc. Oh I’m using Rocket’s Bluezone 3270 emulation.

Clone from https fails with Cloning into … warning: templates not found /var/rocket/git/share/git-core/templates fatal: Unable to find remote helper for ‘https’ I believe 2.14.4 provides support for https.

Does the Git port support, or include, git-lfs or something similar to handle binary elements in a repository or some other way?

Hello, on https://www.rocketsoftware.com/de/zos-open-source/tools the package findutils 4.4.2 is listed to download, the link leads to Rocket Community, but there I couldn’t find a download link for this package. What I’m doing wrong? Kind regards Juergen

Using git with z/OS wouldn’t be possible without Rocket (or it would be more challenging). Using git with ISPF is now a reality. I’ve been working with Henri Kuiper on an ISPF application called zigi - z/OS ISPF Git Interface. At this point, it is still a work in progress but it is usable. Among the things that you will find are: It’s a full ISPF native application ISPF statistics for managed partitioned dataset members are retained Binary datasets (e.g. load modules, object decks) are not supported at this time Check it out at https://zigi.rocks/ And if you’d like to participate please join the fun. Note: zigi does not support just any git repository - for a repository to be used by zigi the repository must be created by zigi. This could change in the future but there are valid reason for this.

Hi all, I have installed vim along with bash, gzip, git. I have followed all the READMEs (at least I think so) and everything is apparently working, but vim shows a strange behavior: every time I start it, the first line shows garbage characters. As soon as I scroll, the garbage disappears and the real text appears. Unfortunately, new files or files which only contain one line cannot be scrolled, so I cannot see the first line. Hints? Thank you in advance! Cris

I have an EBCDIC file that contains various other non-displayable characters that I know won’t round trip from z/OS to GitHub and back. One of the characters contained in my file is a x’14’ which USS sees as a line feed. I don’t need to edit the file in USS. So I OCOPY it in from a PDS member, where the x’14’ means nothing. My .gitattributes file has a line to say all these sorts of files are binary: *.play binary I commit and push the file to GitHub and if I look at it I see that it has been treated as binary, and is not viewable. If I then clone the repo back, then OCOPY the file back to the PDS, the line has been split at the x’14’. According to the git doc for binary - Git will understand that the files specified are not text, and it should not try to change them. Has the Rocket team tried to round trip a binary file containing a x’14’? Did you see the same results?

I’m having trouble installing both python 2 and python 3 in my environment. The installation instructions mention that “extra space savings arise if you download the combined release…” which sounds great. Looking at the installation script, it implies that there should be a single archive containing the combined release. The last step below is what I’m referring to. export RELEASE_DIR=$INSTALL/${RELEASE_NAME}-${RELEASE_TYPE} cd $RELEASE_DIR; ls -ld python27 python36 both # based on the results of the ls, run one or more of these commands cd $RELEASE_DIR/python27; bin/install_all_packages cd $RELEASE_DIR/python36; bin/install_all_packages cd $RELEASE_DIR/both; bin/install_all_packages So this implies there should be an archive containing the combined release called: python-2017-04-12-both.tar.gz However, the only archives available to download are: python-2017-04-12-py27.tar.gz python-2017-04-12-py36.tar.gz Am I misunderstanding the directions? If I do what it says, won’t I will jus

We are using Rocket git Client on Z/OS version 2.14. For timebeing we made our repos as Public so that we can clone without credentials while we setup https or ssh clone. Now when we are trying to push back changes that we made to repository, we get following error. Can anybody help why we are getting this error? fatal: could not read Username for ‘http://testbitbucket.test.net’: EDC5137I Inappropriate I/O control operation. Please also note that we have tried by setting user name as well and getting same error. Thanks and Regards, Danish.

I have a python program that goes through USS directories to look for a certain file with a certain text and writes out the text if that text is not desired. This program was working with binary files coming into program. The issue is now with text files coming in. I am guessing the files coming in are EBCDIC with encoding cp1047. The output error I am seeing is: Traceback (most recent call last): File “/opt/lpp/Rocket-ported/miniconda/lib/python3.7/tokenize.py”, line 385, in find_cookie line_string = line.decode(‘utf-8’) UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0xc1 in position 2: invalid start byte I have tried setting encoding to cp500 with command with open(os.path.join(dirpath, filename), mode = ‘r’, encoding = ‘cp500’) as settingsfile: , and that doesn’t work and produces the above error.

When doing a merge in git how can I generate a report of the files that were deleted? I found this works for files in the repository root but it does not work for files in subdirectories: git show -m --first-parent --name-only Thanks for any direction.

I am trying to use the Make package provided as part of the Rocket Tools for z/OS but am having issues with it when trying to export a value to s system environment in order for it to be used in a sub-make task. With other Make executables on other platforms (and even earlier version on z/OS) this worked - but with the GNU Make v4.1 version this does not work. I have the following test makefiles test1.mk export TEST=xxxx all: first @echo test1_all, $(TEST) first: @echo test1_first, $(TEST) make -f test2.mk test2.mk all: @echo test2_all, $(TEST) When I run the test1.mk file with the following command “make -f test1.mk” I get the following output. test1_first, xxxxx test2_all, test1_all, xxxxx Where it can be seen that in the sub-make file that is called the value for TEST is not set, whereas when the same make files are run on an earlier version (or on another platform) I get test1_first, xxxxx make[1]: Entering directory '/u/groeges' test2_all, xx

Hi, I would like curl write output to mvs dataset. Following writes to dataset USERID.QAPI but changes recordlength to 80 when dataset exists or creates with lrecl 80 if dataset did not exist before : curl -m 15 -v -k --trace qapi.trace -o “//‘USERID.QAPI’” --url “${url}” -K- Following writes to qapi.txt with newline after pos 181 as it should be: curl -m 15 -v -k --trace qapi.trace -o qapi.txt --url “${url}” -K- Is there a qay to have curl use the lrecl from existing dataset or define lrecl in the command? Thx, Frans

hi do we know when we will support python multiprocessing feature, it is currently blocking us to run test cases in parallel, with python2.7, I got error message saying “Multiprocessing is not implemented, because of EDC5257”, what is EDC5257 ? with python 3.6, a simple python program with multiprocessing.Pool feature will hang.

hi I would like to try python 3.7 on zOS, anyone knows where I can find the link to download it. Thanks

I was asked communicating with another Rocket Python user. “Its code is much nicer than REXX. I’d to replace more things which are currently done in REXX with Python. I’m interested in executing commands from different address spaces (i. e. TSO and etc.) using Python; executing IDCAMS commands and etc.” This is an interesting topic. Unfortunately, I have not done much in this area. But was looking out for ways to do this too! One thing that could be done in Python is to spawn a subprocess to execute other programs / unix commands. There is the problem of passing the right parameters and returning the result. At IBM there is Mike Fulton that worked on mvscmd, a c programs that could be called from unix shell to execute z/OS services. Recently, he removed his project from github GitHub mikefultonbluemix - Overview https://about.me/mike_fulton. mikefultonbluemix has 5 repositories available. Follow their code on GitHub. However, it s

For the default Python install, if a user starts a notebook via an ssh session (eg. jupyter-notebook --port=<port#> --ip=<LPAR’s ip>), it sends them a token via their terminal. If a user submits the same command using BPXBATCH however, this token is printed to the batch job’s output (STDERR). This would allow anyone who can read the job’s output on the JES queue to use the token to execute code as the user that submitted the batch job. How have others stopped users from doing this?

When doing a clone it is easy to specify the directory where the clone is to be installed. But the clone will always go into a subdirectory of the specified directory using the name of the repository. Is there a way to change that subdirectory name?

Curious if there is a target date for an update to the ported git. The current git is 2.24.1 and the ported version is 2.14.4. I read the announcement of issues with encoding with git 2.18.x from October 2018 but there is no update for that. Inquiring minds are curious Thanks
