LEGACY - THIS IS NOT A CURRENT METHOD TO MANAGE EPICS MODULE INSTALLATION/DEPLOYMENT AT ESS

E3 Manifest : The single point release method

This repo is the pilot project in order to achieve how we duplicate the exact single point of E3 by using repo [3]. Thus, we evaluate this repo to use generic repo commands and E3 building make rules without introducing any other tools except command line commands.

Requirements

The all E3 module repositories should be selected by a tag or git hash id. They are used to build a E3 manifest file. Each repository has its own corresponding BASE and REQUIRE versions in its RELEASE file.

Possible Scenario

T=t0 : We first setup the production E3 environment
T=t1 : We add the master branch of stream module into the existent production E3 environment
T=t2 : We upgrade the require version
T=t3 : One In-kind would like to duplicate T=t1 E3 in their institute.

However, once we move the different base, require, or both versions, it is much better to move a brand-new manifest file. We can run one by one according to its time order.

Preparation

One needs to setup Repo as follows:

$ mkdir -p ~/bin
$ export PATH=~/bin:$PATH
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Procedure

Consideration

Note that one should not do this job frequently, after this, most of work will be done by individual modules. We may develop a better tool to setup it later.

Step 1: Create a directory

$ mkdir e3_env
$ cd e3_env

Step 2: Init

Initialize epics_env to use the default.xml [4] on the master branch

e3_env $ repo init -u https://github.com/icshwi/e3-manifest

Step 3: Sync

e3_env $ repo sync --no-clone-bundle

Step 4: Build

This step is only valid for the case when one would like to install E3 from scratch. The simple building rule is

cd a_specific_version_of_module_which_one_would_like_to_install
make init
make patch
make build
make install

BASE

e3_env $ repo forall --groups=base -c 'make init && make patch && make build'

e3_env $ cd 0.epics-base/
0.epics-base ((7.0.3.1-NA/R-7.0.3.1-778a693-1911112218))$ make init
0.epics-base ((7.0.3.1-NA/R-7.0.3.1-778a693-1911112218))$ make patch
0.epics-base ((7.0.3.1-NA/R-7.0.3.1-778a693-1911112218))$ make build
0.epics-base ((7.0.3.1-NA/R-7.0.3.1-778a693-1911112218))$ cd ../

Note that make all does not exist for BASE.

REQUIRE

e3_env $ repo forall --groups=require -c 'make init && make patch && make rebuild'

e3_env$ cd 0.00.require/
0.00.require ((7.0.3.1-3.1.2/R-3.1.2-e0c84e4-1911121821))$ make init
0.00.require ((7.0.3.1-3.1.2/R-3.1.2-e0c84e4-1911121821))$ make patch
0.00.require ((7.0.3.1-3.1.2/R-3.1.2-e0c84e4-1911121821))$ make build
0.00.require ((7.0.3.1-3.1.2/R-3.1.2-e0c84e4-1911121821))$ make install
0.00.require ((7.0.3.1-3.1.2/R-3.1.2-e0c84e4-1911121821))$ cd ..

e3_env $ repo forall --groups=require -c 'make all'

Common modules

e3_env$ repo forall --jobs=1 --groups=common -c 'make all'

Timing modules

e3_env$ repo forall --jobs=1 --groups=timing -c 'make all'

PSI modules

Note that Common modules group should be installed before.

e3_env$ repo forall --jobs=1 --groups=PSI -c 'make all'

IOxOS modules

Note that Common modules group should be installed before. And currently, few repositories need an access permission. Please contact us for the permission.

e3_env$ repo forall --jobs=1 --groups=ioxos -c 'make all'

AreaDetector modules

Note that Common modules group should be installed before.

e3_env$ repo forall --jobs=1 --groups=areaDetector -c 'make all'

Ethercat modules

Note that one should install the etherlab master first. Please see the reference [5]. And Note that Common modules group should be installed before.

e3_env$ repo forall --jobs=1 --groups=ethercat -c 'make all'

Step 5: Set the E3

e3_env $ source /epics/base-7.0.3.1/require/3.1.2/bin/setE3Env.bash
e3_env $ iocsh.bash

Additional commands

Output messages will be redirected

One needs to type space key from time to time in order to see all outputs such as stdin, stdout, stderr.

e3_env$ repo forall --jobs=1 -p --groups=ethercat -c 'make init && make patch && make -s rebuild'

Initialize a repo with a specific manifest file

repo init -u https://github.com/icshwi/e3-manifest -m a_specific_manifest.xml

Force Sync

repo sync --force-sync --no-clone-bundle
