bob's Introduction

Bob Build Tool

Bob is a build automation tool inspired by bitbake and portage. It is intended for complex embedded projects and thus focuses on reproducible builds while still being nice to developers in agile environments.

Installation

To install the latest release just do a:

$ python3 -m pip install BobBuildTool [--user]

See the installation instructions for more information and other methods.

Getting started

It's probably the best to head over to the documentation. To get an impression of how Bob is configured, have a look at the tutorials. A real project that is built by Bob can be found here.

The Cheat Sheet shows common used keywords and commands.

If you have a specific question you're welcome to post on the mailing list (FreeLists).

bob's Issues

Audit trail

Binary artifacts should have some meta data attached to them to get the recipe/package that created them. Additionally there should be some information about the input of the package, e.g.:

build host/time
environment
dependencies (with their respective audit trail)
state of SCMs (e.g. commit id, dirty, ...)

This information must be structured so that it can be parsed by other tools.

bob project --resume

run bob project without -n to let bob execute bob dev
if there is a error you'll get a message: You may resume at this point with '--resume' after fixing the error.

But there is no --resume arg available for bob project.

jenkins: Don't discard builds when package is added by --add-root

When you add a non-root-recipe-package to jenkins with --add-root, the generated job discards old builds. I think they should persist - is it intentional or not? When the recipe has "root: True" it won't be generated with this feature.

Code line: https://github.com/BobBuildTool/bob/blob/master/pym/bob/cmds/jenkins.py#L473

multiPackage with MultiSources after remove of pickle module

Hi Jan,
I merged your commits this morning. I think db49f07 brought in a regression when using multiPackage recipes. Without this commit there is only one source directory and different build / dist directories.
Now there is a separate source directory for each multiPackage package. After reverting db49f07 it's building from the same src again.

jenkins: when creating jobs with --no-sandbox jobs can't be build

When creating Jobs with "jenkins push" and "--no-sandbox" jobs can't be build because of missing sandbox dependencies. The jobs won't be generated but it wants to use it for calculating the buildid.

Implement shared packages for local builds

On Jenkins shared packages (shared: True) are installed into a common location. It would be nice to have that too for local builds. This feature would require a cleanup method too, though. Otherwise a user could not tell which packages in the common location are still referenced.

blackbox test not working inside venv

When starting test/run-tests.sh from inside a venv and the system lacks some dependencies, the test fails. This looks like the test is somehow not started inside the venv.

pip list | grep python-magic

is empty. Then entering the venv

source /.../pyvenv/bob/bin/activate
pip list | grep python-magic

returns the package name and version as expected. Now running test/run_tests.sh gives this error:

Run test/generator

buildStep doesn't know it's name

At the moment there is no possibility to get the complete step name (e.g app/module1/module2) in the build or package step.
This can be useful, if you create module-wise-project files from bob...

"bob dev" does not work intuitively with binary artifacts when source comes from tags/commits

When working with "bob dev" the developer expects to be able to change any of the involved sources, call bob again and it will rebuild with the changes. If binary artifacts are used and the sources are deterministic this is not true anymore. The problem is that Bob treats deterministic sources different. For these the actual sources are irrelevant and the binary artifact is downloaded just by looking at the configured tag/commit.

Steps to reproduce with bob-tutorials/binary-repository:

bob build --upload root
bob dev root/lib/
echo "#error" >> dev/src/lib/1/workspace/lib.c
bob dev --download=yes root/

Instead of tripping over the #error Bob will happily download the artifact for "root":

$ bob dev --download=yes root/
>> root
   DOWNLOAD  dev/dist/root/1/workspace...ok
Build result is in dev/dist/root/1/workspace

Possible fixes:

Don't treat tags/commit special
This will always checkout all involved sources first, create a hash sum and use that as the access key for the binary artifact. This is already the behavior for checkouts from branches.
- Pro: consistent definition, will remove special handling of tags/commits, make download decision stateless
- Con: will download all sources even if not strictly needed, more overhead when building a large tagged software
Use current handling of tags/commits and verify that sources are unchanged
For packages that have their sources checked out it is verified that they were not modified by the user. This validates that the downloaded artifact can be used.
- Pro: old artifacts are compatible, release mode could stay fast
- Con: complicated to implement and complicated semantics, download artifacts may be thrown away, requires audit trail
Use two build-ids, one for special handling and one for full source hashes
In release mode Bob could use the current defintion to download artifacts as early as possible. In develop mode Bob could use the source-based build-id to behave like in 1.
- Pro: Optimal behavior in develop/release mode
- Con: requires double uploads or symlinks (not possible with webdav), breaks all archive backends, special handling just for release builds from tags

GitSCM: "tag:" now adds "tags/" for checkout step

In e3d254c there is an additional change that adds "tags/" to the parameter given by tag:.

We use the tag parameter of GitScm to get the branch, tag or commit from a multipackage with a variable:

checkoutSCM:
    scm: git
    url: [email protected]:example/example_common.git
    tag: ${SCM_REVISION}

multiPackage:
    lib-v2.3.0:
        root: true
        environment:
            SCM_REVISION: "v2.3.0"

Is there another way for doing this? It's a workaround to handle different versions of a package inside one recipe, to tackle the problem of recipe reuse.

Incremental build failed

Steps to reproduce:

build a package -> success
add error in sources, rebuild package -> BUILD step fails
revert changes to sources, rebuild -> BUILD step is not executed -> FAIL

The problem is that Bob does not invalidate the result and input of the build step prior to building it.

jenkins: support jenkins on windows host using msys2

Jenkins implementation is limited to unix hosts running jenkins. There are some toolchain's only available for windows... :-(

make developNamePersister hookable

should be possible to add a own implementation there. e.g. to get rid of the number if only one directory exists...

Sandbox preconditions

It would be nice to have some words about how a sandbox should look like in the docs.

Things I found by experiment (and by peeping into basement):

there must be a etc/passwd file containing the "nobody" user ("src/namespace-sandbox/namespace-sandbox.c:599: User not found in /etc/passwd of sandbox")
there must not be a home directory ("src/namespace-sandbox/namespace-sandbox.c:480: cannot create /tmp/tmp.hSetADl61X/home/stefan: Read-only file system")
there must not be a tmp directory (same)
the sandbox must have bash 4 (on a second thought this is not too surprising given bob uses associative arrays; my old toy sandbox has bash 2)

It might have helped in debugging if bob would at some level of -vvv pass -D to namespace-sandbox.

completion broken for zsh

Since the "bash-completion: handle colons in COMP_WORDBREAKS"-commit in contrib/bash-completion its broken for zsh:

bob vs jenkins

ok, playing around with Jenkins (Weekly release "2.19 war" from jenkins.io):

Two things I found by experiment, which should be in the docs:

Jenkins must have CSRF disabled (Configure Global Security -> [ ] Prevent Cross Site Request Forgery exploits), otherwise, bob bounces off using "HTTP error: 403 No valid crumb was included in the request". Probably the better solution would be to implement that in bob...
Jenkins needs access to bob binaries (bob-hash-engine), not just the "expected" build tools; was not on my default $PATH

Endless loop if class.yaml inherits from itself

Hi,
recently I accidentally inherited in a class the class itself and bob was running forever with no output. Maybe it would be nice if bob can detect this kind of error and exit with a proper error message. I had no clue what was happening and only discovered the error by doing a diff over my changes.

Steps to reproduce

in classes directory, insert at the top of a classname.yaml: inherit: [classname]
run bob command, e.g bob ls -r
(Ctrl-C)

RFD: make shell easier to use

What I want to do: for debugging a build, I'd like to execute commands in the workspace. Could be gdb. Could be make test. Could be make myfile.i. Could be ./configure. Right now, I have to figure out the workspace directory, and do something like build.sh shell. However, even if I do that, I'm still missing shell functions and most variables I defined in my recipes. Wouldn't it be nice to have a command like bob shell <mypackage>?

Idea: I made a prototype of a bob shell command (in perl, sorry; see attached file). Right now, this parses the script that bob places in each directory using some ad-hockery, and generates a new rcfile, which it then gives to an interactive bash. This shell has environment variables set and functions defined (the script is parsed up to the first line my ad-hoc parser does not understand, which is usually a command invocation).

How could we do this in bob directly? porting the perl to python would be trivial. A much better solution, however, would be to allow users to split setup and execution of a step. Instead of, say, buildScript, you specify buildSetup + buildScript. For building, both are concatenated to produce the same result as now. For the shell, just execute the buildSetup parts.

bob clean: extend for dev mode

Currently "bob clean" is only doing something in the "work" directory of release mode builds. For development mode at least two things need to be considered:

directories that are not referenced anymore
attic directories from obsolete checkouts

Source and/or attic directories must only be deleted if the user explicitly requested to do so.

default.yaml: add include support

some of the environment variables from defaul.yaml may not fit to the local system.

Therefore I added a include - option in the default.yaml to update the defaultEnv with the content of the given additional file.

--force option not working anymore.

When trying to force build a single package with

bob build path/to/package/ -f -b -n --clean

the building of the dependencies is correctly skipped (because of -n, though the messages state "due to --build-only" which might be OK here, too) but building of the target package is skipped, as well:

PACKAGE   skipped (deterministic output in work/…/dist/1/workspace)

I guess this is not the intended behaviour of the --force switch.

My bob version is

Bob version 0.12.0-71-gb74766d

invalid variable name in script

steps to reproduce:

generate a recipe with a '-' , e.g. recipe-name.yaml
in this recipe use file inclusion syntax $<<file>>
this will generate a script with: _recipe-name0=$(mktemp)

The '-' is not allowed in ubuntu's bash. (GNU bash, Version 4.3.11(1)-release (x86_64-pc-linux-gnu))

Parsing of big projects is slow

Parsing of big projects with many variants is slow and memory consumption is getting a concern too. Instead of traversing the whole dependency tree the descent should be stopped if a package has already been calculated.

generator test is broken

The test/blackbox/generator is broken:

support additional config file

Idea behind this is to name another yaml file on the commandline interface to setup some (e.g. platform specific) Environment variables. This can dramatically reduce the number of multiPackages or recipies. They can be more generic now.

git checkout reference fails because of fetch flag

When having a commit hash in a recipe git fails to checkout because of "fatal: reference is not a tree:"
The problem is the referenced line in git.py:

https://github.com/BobBuildTool/bob/blob/master/pym/bob/scm/git.py#L96

When doing "git fetch -t origin" you just fetch the tags. Instead of this it should do "git fetch origin" to get the commit references as well as the tags.
