## The CMake Build system
|
||||
|
||||
FOSSology is quite an old and mature project. The project has been using
|
||||
bare metal **Makefiles**. As the project is growing with new agents and
|
||||
modernization it was required to have a modern build system.
|
||||
|
||||
The FOSSology is a suite of well-integrated and synchronized
|
||||
sub-projects (called agents) written in C, C++, and PHP. Most of the
|
||||
major agents are in C, C++ and that made CMake an obvious choice for a
|
||||
new build system for FOSSology. CMake is a versatile set of build, test,
|
||||
and packaging tools and is the most popular choice of C/C++ developers.
|
||||
CMake can be extended to create a build system for other languages too
|
||||
via custom scripts.
|
||||
|
||||
## GitHub Actions CI/CD
|
||||
|
||||
Since the FOSSology project moved on Github, it has used only the free
|
||||
Travis CI service for OSS projects. At the time of writing Travis CI has
|
||||
reduced its free tier CI services. GitHub Actions provides faster
|
||||
builds. Since GitHub Actions is a fully managed service by GitHub, we
|
||||
don't need to know how to scale and operate the infrastructure to run
|
||||
it.
|
||||

|
||||
|
||||
It is straightforward to use with GitHub because when we fork a
|
||||
repository, the actions automatically get forked. This allows you to
|
||||
test and build projects very efficiently and even run them closer to the
|
||||
developer. Also, you have readily available access to the GitHub API,
|
||||
making it more popular among developers.
|
||||
|
||||
## Improvements over previous build system and CI
|
||||
|
||||
The new build system and CI brings a lot of improvements and features.
|
||||
The list below describes them.
|
||||
|
||||
- CMake enforces out-of-source builds. This was already possible with
|
||||
the previous build system but not a strict requirement. This feature
|
||||
keeps the source code clean and makes cleaning the build artifacts
|
||||
easy. (Just remove the build folder :)
|
||||
- One of the major improvements over the previous build system is faster
|
||||
build times. CMake generates parallel build-enabled configurations for
|
||||
all generators. In our tests, the new build system is at least twice
|
||||
as fast as the previous one. With further improvement in
|
||||
configuration, we will be able to further cut the build times.
|
||||
- Previously FOSSology can only be built using *Unix Makefiles*. With
|
||||
CMake, we can now use many other popular generators such as *Ninja*.
|
||||
- Now it is also very flexible to choose different compilers. This will
|
||||
help support more platforms and architecture in the future. As of now,
|
||||
we are experimenting with Clang compilers.
|
||||
- FOSSology is quite an old project and a lot of agent testing code was
|
||||
written in the last decade. Initially, none of them were compatible
|
||||
with the new build system, but we were able to hack most of the test
|
||||
code using better-improved methods. Test times have also improved.
|
||||
- Migrating from Travis CI to GitHub Actions was another big move and
|
||||
for the most part, it removes the dependency on a third-party CI
|
||||
service. Along with that GitHub Actions provides better build times,
|
||||
tons of new features, and better integration with other GitHub
|
||||
services.

## How does it work and how to use it?
|
||||
|
||||
The new build system retains the modular and hierarchical structure of
|
||||
the previous build system. On the other hand, the new build system
|
||||
provides several new flags to control the build. The new build system
|
||||
forces out-of-source build instead of the previous in-source builds.
|
||||
This keeps the source clutter-free and reduces the chance of
|
||||
accidentally deleting source files. *Testing still needs some in-source
|
||||
artifacts, this will be solved once all the tests are fixed according to
|
||||
the new build system.*
|
||||
|
||||
Each agent is a complete CMake sub-project with its independent
|
||||
configuration for building, installing, and testing. That means a single
|
||||
agent can be built and installed separately and even removed from the
|
||||
default build without breaking other builds. The directory structure is
|
||||
as below.
|
||||
|
||||
```bash
|
||||
.
|
||||
├── build # temporary directory for build artifacts
|
||||
├── cmake # CMake modules for FOSSology
|
||||
│ ├── FoPackaging.cmake # CMake Packaging configurations
|
||||

|
||||
:
|
||||
├── other directories and files
|
||||
:
|
||||
└── CMakeLists.txt # FOSSology Top-level CMake configuration
|
||||
```
|
||||
|
||||
The `cmake` directory contains customized CMake modules and templates
|
||||
for FOSSology. This directory is required for all the operations. The
|
||||
general workflow of the new build system as well as how to use it is
|
||||
described below.
|
||||
|
||||
1. Since the new build system is still in review. You must fork
|
||||
FOSSology and pull the
|
||||
[#2075](https://github.com/fossology/fossology/pull/2075) pull
|
||||
request branch. Once you are in FOSSology root, run these commands.
|
||||
|
||||
```bash
|
||||
git fetch https://github.com/avinal/fossology avinal/feat/buildsystem:buildsystem
|
||||
git checkout buildsystem
|
||||
```
|
||||
|
||||
2. The first step towards building is to create a temporary directory
|
||||
for storing intermediate files and build artifacts. By convention we
|
||||
use a directory named `build`, but you can use any name. (**NOTE:
|
||||
For testing do not use other names**)
|
||||
|
||||
```bash
|
||||
mkdir build
|
||||
cd build
|
||||
```
|
||||
|
||||
3. In the next steps, we will configure the CMake project and generate
|
||||
the required configurations. You can use several flags to control
|
||||
the build. Given below are the flags available for this project.
|
||||
|
||||
<table style="width:99%;">
|
||||
<colgroup>
|
||||
<col style="width: 34%" />
|
||||
<col style="width: 43%" />
|
||||
<col style="width: 20%" />
|
||||
</colgroup>
|
||||

|
||||
<tbody>
|
||||
<tr class="odd">
|
||||

|
||||
<td>Sets the install prefix.</td>
|
||||

|
||||

|
||||
<tr class="odd">
|

|

|

<tr class="odd">
|
||||

|
||||

|
||||
<td><em>Unix MakeFiles</em></td>
|
||||
</tr>
|
||||
</tbody>
|
||||
</table>
|
||||
|
||||
There are lots of inbuilt CMake command-line options you can see
|
||||
them in the official
|
||||
[documentation](https://cmake.org/cmake/help/v3.10/manual/cmake.1.html).
|
||||
Once you have chosen your flags we can now configure the project
|
||||
using the following commands.
|
||||
|
||||
```bash
|
||||
# From build folder
|
||||
cd <name-of-build-directory>
|
||||
cmake <flags> ..
|
||||
```
|
||||
|
||||
4. The next step is to build the project. You can use parallel jobs to
|
||||
build faster. For more options you can type `cmake --help` or
|
||||
`make --help` or `ninja --help`.
|
||||
|
||||
```bash
|
||||
# Common build command for all generators,
|
||||
# Default number of parallel builds depends on generator used
|
||||
cmake --build . --parallel <no-of-processes>
|
||||
|
||||
# For Unix Makefiles, no parallel build by default
|
||||
make -j <no-of-processes>
|
||||
|
||||
# For Ninja, 8+ parallel build by default (depends on system)
|
||||
ninja -j <no-of-processes>
|
||||
```
|
||||
|
||||
5. Installing is also as easy as building. You can choose to install
|
||||
only certain components even if you have built the whole project. If
|
||||
you directly invoke the install command without building the
|
||||
project, it will automatically build the project first.
|
||||
|
||||
```bash
|
||||
# For Unix Makefiles
|
||||
make install
|
||||
|
||||
# For Ninja
|
||||
ninja install
|
||||
```
|
||||
|
||||
6. While testing has some issues, most of the testing is working fine.
|
||||
For now, you must build and run any test from the FOSSology root
|
||||
directory only. You can choose to configure a single agent if you
|
||||
want to test one agent only. See `ctest --help` for controlling test
|
||||
runs.
|
||||
|
||||
```bash
|
||||
# Common testing command
|
||||
ctest --parallel <no-of-processes>
|
||||
|
||||
# For Unix Makefiles
|
||||
make test
|
||||
|
||||
# For Ninja
|
||||
ninja test
|
||||
```
|
||||
|
||||
7. You can package FOSSology, the packaging currently lacks copyright
|
||||
and conf files. But for testing purposes, you can use the following
|
||||
commands. Similar to installing, if you run the package command
|
||||
without building the project, it will automatically build the
|
||||
project first. See `cpack --help` for more packaging options.
|
||||
|
||||
```bash
|
||||
# Common testing command
|
||||
cpack
|
||||
|
||||
# For Unix Makefiles
|
||||
make package
|
||||
|
||||
# For Ninja
|
||||
ninja package
|
||||
```
|
||||
|
||||
## Known Issues and Drawbacks
|
||||
|
||||
Although the transition from Makefiles to CMake and Travis CI to GitHub
|
||||
Actions is almost complete and working as expected. But it is not free
|
||||
of drawbacks and issues. This section outlines the known issues at the
|
||||
time of writing.
|
||||
|
||||

|
||||
|
||||
- Coverage builds may fail with linking errors.
|
||||
- Packaging prefix is the same as the install prefix. This requires the
|
||||
developer to set the install prefix manually before packaging to
|
||||
produce packages with the correct directory structure.
|
||||
- Testing and packaging must be used from the FOSSology root directory.
|
||||
Not doing so may or may not configure the project as intended.
|
||||
- Previously tests were written hardcoded for the Makefiles. But new
|
||||
build system requires all artifacts to be generated in a separate
|
||||
directory. This required me to add symbolic links wherever a generated
|
||||
script or file is expected. Tests can still leave some artifacts
|
||||
inside source folders.
|
||||
- There is no easy way to install a particular agent from the FOSSology
|
||||
root directory.
|
||||
- Packages don't contain copyright, readme, and license files. CMake
|
||||
doesn't provide a way to include these files. This is being tracked by
|
||||
issue
|
||||
[#21832](https://gitlab.kitware.com/cmake/cmake/-/issues/21832).
|
||||
- While packaging the symbolic links may or may not be dereferenced and
|
||||
hence results in copying the folder too in the target directory.
|
||||
- Running tests locally may require switching to `fossy` user.
|
||||
- While configured for testing, it may give permission errors.
|
||||
- Scheduler, Ununpack, and Delagent unit and functional tests are not
|
||||
working. I have added an issue
|
||||
[#2084](https://github.com/fossology/fossology/issues/2084) to track
|
||||
the progress on fixing these tests.
|
||||
- CMake doesn't generate uninstall targets. The closest thing to
|
||||
uninstall is [this snippet](https://gitlab.kitware.com/cmake/community/-/wikis/FAQ#can-i-do-make-uninstall-with-cmake).
|
||||
This will be later added to the FOSSology.
|
||||
|
||||
## Challenges Faced
|
||||
|
||||
While this whole project was challenging, some aspects of it were
|
||||
unforeseen and more challenging. When I decided to go on with this
|
||||
project I just had enough CMake knowledge to write a configuration for a
|
||||
very small project. I had never used CMake on this big scale. On the
|
||||
other side, the FOSSology community is largely unknown to CMake so for
|
||||
all of us it was learned, practiced, and implement. With support from
|
||||
mentors, I was able to overcome this challenge with flying colors.
|
||||
|
||||
The other challenge was to understand the old build system, how they are
|
||||
all connected and what is the flow. The complexity can be imagined by
|
||||
the fact that the most of code and configurations were written in the
|
||||
decade before the last decade and haven't changed much since then.
|
||||
|
||||
The most challenging task was to make tests work with the new build
|
||||
system. Since tests were mostly hardcoded and the new build system
|
||||
refactored many of the files and directory, the tests were failing
|
||||
initially. The testing part took me the most time. All thanks to my
|
||||
mentor Gaurav, I was able to hack them to suit the
|
||||
new build system.

||||

## Future Development Plans
|
||||
|
||||
There is a lot to do with the new build system and CI and it will
|
||||
probably take a year or to reach a maturity point. I was able to meet
|
||||
most of the goals but some of them are remaining.
|
||||
|
||||
- Fix the tests, probably renovate them from the ground up.
|
||||
- Find a hack for packaging problems.
|
||||
- Improve and optimize the build.
|
||||
- Modernise the source code, remove old, bloated code and replace them
|
||||
according to new standards.
|
||||
|
||||
## What did I learn from this project?
|
||||
|
||||
This Google Summer of Code was the busiest time of my life for all good
|
||||
reasons. I learned a lot about license compliance and how it all works
|
||||
in the software industry. The next big thing is CMake. As I mentioned I
|
||||
was just a novice user of CMake. Now I am confident that given any other
|
||||
large project I will be able to migrate it/improve it. I got to learn
|
||||
PHP, of which I did not know a single word before GSoC. And finally, I
|
||||
learned about packing and testing. I had these courses but implementing
|
||||
them myself and fixing them was a wholesome experience.
|
||||
|
||||
Other than that I improved on my communication and presentation skills.
|
||||
Collaborating with fellow participants was one of the great things that
|
||||
happened during GSoC.
|
||||
|
||||
## Acknowledgments
|
||||
|
||||
Google Summer of Code is the best thing that has happened to me this
|
||||
year so far. Although there are numerous people to say thanks to, I want
|
||||
to mention key people who were my motivation and support during this
|
||||
period.
|
||||
|
||||
First of all, I want to thank and appreciate my mentors [Gaurav
|
||||
Mishra](https://github.com/GMishx), [Michael C.
|
||||
Jaeger](https://github.com/mcjaeger), [Anupam
|
||||
Ghosh](https://github.com/ag4ums), and [Shaheem Azmal M
|
||||
MD](https://github.com/shaheemazmalmmd). Without the help and support
|
||||
from them, all this would not have been possible. They are very polite,
|
||||
knowledgeable, and helpful.
|
||||
|
||||
Finally, I want to thank, my family and friends. I got to meet many
|
||||
awesome developers as my fellow participants from around the world, I
|
||||
wish we will do more collaboration in the future.

## Updates
|
||||
|
||||
In the first phase of GSoC 2021 @ The FOSSology Project, I have
|
||||
completed the desired milestone. As of now, FOSSology can be installed
|
||||
completely via CMake and most of the components are working fine in
|
||||
initial testing.
|
||||
|
||||
List of tasks completed
|
||||
|
||||
- Added CMake build configurations for all the C/C++ agents for
|
||||
executables, libraries, and coverages
|
||||
- Added CMake install configuration for all C/C++ and PHP agents as well
|
||||
as extra components
|
||||
- Reworked the shell scripts and generated source files to make them
|
||||
more compatible with CMake as well as better in terms of overall
|
||||
compatibility with the latest tools.
|
||||
|
||||
## Improvements
|
||||
|
||||
- The new CMake build architecture is much more flexible to changes as
|
||||
compared to hard-coded Makefiles.
|
||||
- CMake generated configurations support parallel build by default, this
|
||||
has led to significant improvement in build time. CMake generated
|
||||
configuration can now build the whole project within 2 mins or even
|
||||
faster on more powerful CPUs (Both Ninja and Makefiles with the same
|
||||
number of parallel processes) compared to 4-5 minutes previously.
|
||||
*(These results are averaged from initial testing of new build
|
||||
architecture)*
|
||||
- CMake supports out-source builds by default, which means the source
|
||||
folders are not touched/modified while building, all build files and
|
||||
residuals get their separate folder and the source tree can be cleaned
|
||||
easily.
|
||||
- Developers can now opt for a long list of generators to build
|
||||
FOSSology e.g Makefiles, Ninja as per their needs.
|
||||
|
||||
## How to test
|
||||
|
||||
Instructions to test the new Build system is in [this](https://github.com/avinal/fossology/wiki#test-the-new-system-only-gcc-with-make-and-ninja-tested-for-now) wiki.
|
||||
|
||||
## Known Issues
|
||||
|
||||
- There may be a permission issue with some generated sources while
|
||||
building. This can be bypassed for now by running
|
||||
`sudo chmod +x <filename>` command.
|
||||
- Coverage builds may fail.
|
||||
|
||||
## Postponed Tasks
|
||||
|
||||
- configuration for tests are skipped for now
|
||||
|
||||
## Work in Progress
|
||||
|
||||
- Currently, I am working on packaging the FOSSology with CMake.

This meeting is the first of the recurring weekly GSoC project meetings. In this meeting the current status of progress according to the proposal was discussed and some topics related to current build system based on Make and the new build system based on CMake.
|
||||
|
||||
## Discussions
|
||||
|
||||
- **The current progress according to schedule**
|
||||
- The blog on CMake is on the way.
|
||||
- I have gone through the Makefiles to get a rough estimate of the
|
||||
work.
|
||||
- Published the GSoC project blog
|
||||
- **How are agents related to each other in terms of compilation?**
|
||||
- Each agent is independently compiled and generally use the source
|
||||
code in `lib` folder. If any agent needs other agent then it uses
|
||||
the library files instead.
|
||||
- **Does every agent have a executable and library?**
|
||||
- Not necessarily, there are agents written in C, C++ and PHP,
|
||||
depending on what is the use the configuration can be different.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- It would be better if I get started by creating CMake configuration
|
||||
for any of the agent.
|
||||
- Fork and create a branch for development and mention the same in blog
|
||||
or wiki.
|
||||
- Add a timeline section in blog or wiki as provided in the project
|
||||
proposal.
|
||||
- Publish the CMake introductory blog.
|
||||
- Prepare a prototype/plan for next week.
|
||||
- Find out the best alternative for handling the global variables.

title: Community Bonding Meeting 1
|
||||
---
|
||||
|
||||
In this second meeting points over default Makefiles were discussed. Ninja can be used as an alternative for Makefiles.
|
||||
|
||||
## Discussions
|
||||
|
||||
- **What is the use of** `Makefile.deps` **and** `Makefile.process`
|
||||
**files?**
|
||||
- `Makefile.deps` consists of many used and unused snippets. These
|
||||
snippets help setup the build and test environment for fossology.
|
||||
Since there are many directories that are hardcoded, special care is
|
||||
required while replacing this file.
|
||||
- `Makefile.process` generates a master variable from list of
|
||||
variables. It assists the script in `Makefile.conf` file. These
|
||||
files together generate a list of variables that can be used
|
||||
throughout the build process.
|
||||
- The build can be made faster using **Ninja** instead of **Make**.
|
||||
- Ninja supports parallel builds by default.
|
||||
- Print the flags used once the CMake configuration is working. That
|
||||
will help us debug the process.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Write a *CMakeLists.txt* for **lib**.
|
||||
- Push the working branch and update the link either on wiki or blog.

|

This week I worked on CMake testing configuration. Most of the time was spent understanding the previous testing architecture.
|
||||
|
||||
## Week 9 Progress
|
||||
|
||||
> Initial CMake testing configuration added.
|
||||
>
|
||||
> - Few tests working, e.g copyright, nomos
|
||||
> - Improved packaging configurations
|
||||
> - To test the current progress, follow the instructions [here](https://github.com/avinal/FOSSology/wiki#test-the-new-system-only-gcc-with-make-and-ninja-tested-for-now)
|
||||
|
||||
## Discussions
|
||||
|
||||
- **Is this a necessity that tests must be run as the fossy user?
|
||||
Because when I run tests as me they as for permissions. But proceeds
|
||||
as the fossy user.**
|
||||
|
||||
- No this is not required and this should not happen. They run under
|
||||
fossy as they sometimes require writing into /srv/fossology. But if
|
||||
they can run under other users that is an enhancement.
|
||||
|
||||
- **I am getting a lot of install issues in C/C++ agent tests?**
|
||||
|
||||
``` bash
|
||||
Start 3: delagent_unit_test
|
||||
|
||||
3: Test command: /home/avinal/Documents/my_git/fossology/build/src/delagent/agent_tests/test_delagent
|
||||
3: Test timeout computed to be: 10000000
|
||||
3: install: cannot stat '/home/avinal/Documents/my_git/fossology/build/src/delagent/agent_tests/..//../../install/defconf/Db.conf': No such file or directory
|
||||
3: install: cannot stat '/home/avinal/Documents/my_git/fossology/build/src/delagent/agent_tests/..//VERSION': No such file or directory
|
||||
3: sh: 1: ../../../testing/db/createTestDB.php: not found
|
||||
3: Failed to run ../../../testing/db/createTestDB.php -c /home/avinal/Documents/my_git/fossologbuild/src/delagent/agent_tests/testconf -e, exit code is:127 .
|
||||
3/8 Test #3: delagent_unit_test ...............***Failed 0.02 sec
|
||||
```
|
||||
|
||||
- Not sure about the reason. I was suspecting Makefile but since they
|
||||
are gone now, I think PHP files are calling some shell commands
|
||||
causing this.
|
||||
|
||||
- **Suggestions/Changes from Gaurav for fixing tests.**
|
||||
|
||||
- For clib-tests, it needs to be called from PHP file (via PHPUnit) as
|
||||
it requires setting up a dummy repo. Check the
|
||||
`src/lib/c/test/Makefile`
|
||||
- For missing services.xml, the test cases include
|
||||
`src/lib/php/common-container.php` which loads the file. It expects
|
||||
it to be in current dir. Can be solved in two ways
|
||||
- Create another common-container.php just for test cases with
|
||||
correct paths.
|
||||
- Edit the current file and take the help of environment variables.
|
||||
For example, if a test variable is exported in env, find the XML
|
||||
relative to it otherwise continue as normal and this variable can
|
||||
be exported by CMake during the test.
|
||||
- Scheduler tests do need `fossology_testconfig` from Makefile.deps
|
||||
which set up the srv and create test configurations, DB, etc.
|
||||
- Another shell script can be written to do all that and call it
|
||||
from CMake. The PHP file called makes everything required in /tmp
|
||||
so not an issue.
|
||||
- The locations like `LOG_DIR, FOSSDB_CONF`, etc. in CMakeLists.txt
|
||||
can be changed to some other values. I am guessing this is the
|
||||
reason you were asked for the fossy password.
|
||||
- File `src/copyright/agent_tests/Functional/cli_test.sh` needs to be
|
||||
edited to take paths relative to build dir. It can also be made into
|
||||
a .in file which is generated from CMake? So every path can easily
|
||||
be updated.
|
||||
- For PHP agents with missing version.php issue, there is a hack
|
||||
possible
|
||||
- Check
|
||||
<https://www.php.net/manual/en/function.set-include-path.php>
|
||||
- Another hack will be to use soft links for version.php in the
|
||||
source.
|
||||
- Other PHP issues like
|
||||
`PHP Fatal error: Uncaught Error: Class 'Fossology\Lib\Agent\Agent' not found`
|
||||
can only be solved by editing composer.json before doing composer
|
||||
install (look for autoload: psr-4 ).
|
||||
- For delagent, pkgagent, mimetype issues, something can be done here:
|
||||
<https://github.com/avinal/fossology/blob/avinal/feat/testing/src/testing/db/c/libfodbreposysconf.c#L349>
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Raise a pull request for all the progress till now.
|
||||
- Refactor the test source code according to suggestions.
|
||||
- Implement remaining testing configurations.

|

## Week 9 Progress
|
||||
|
||||
> Testing configuration for all agents added
|
||||
>
|
||||
> - GitHub Actions Configuration added
|
||||
> - Fixed and refactored most of the tests

|

|
||||
## Discussions
|
||||
|
||||
- **I suspect that the Ojo regression test's expected data file is
|
||||
outdated**
|
||||
- Michael said that on their internal Jenkins CI, these tests are not
|
||||
being run currently, so this might be possible that the file is
|
||||
outdated.
|
||||
- **Since some of the tests need Makefile to install while testing,
|
||||
CMake generated Makefiles and test Makefiles are conflicting, and
|
||||
hence we are forced to use Ninja for testing. What can I do about
|
||||
it?**
|
||||
- Michael suggested using `--file=filename` flag with the make command
|
||||
and change the name of the test Makefile to something else. This
|
||||
will solve the problem.
|
||||
- **Mimetype is detecting executables as shared lib, is that expected or
|
||||
needs to be fixed?**
|
||||
- Mimetype internally depends on the *file* command to get the
|
||||
mime-type. If the output of the *file* command is also the same then
|
||||
it is okay.
|
||||
- **What is** `folderlist` **in
|
||||
<https://github.com/fossology/fossology/blob/master/src/delagent/agent_tests/Functional/ft_cliDelagentTest.php#L126>
|
||||
?**
|
||||
- `folderlist` is a view. Use `createViews()` function.
|
||||
- **Suggestions/Changes from Gaurav for fixing phpunit tests.**
|
||||
- Please note the changes in `setUp()` function in
|
||||
`src/lib/php/tests/test_common_license_file.php`
|
||||
- The test database name is given to the constructor of TestPgDb and
|
||||
can be anything as it gets deleted in `teardown()`
|
||||
- The `dbmanager` is provided by the object, no need to initialize
|
||||
global `PG_CONN` (it will be exposed by the library in case some of
|
||||
the functions need it).
|
||||
- All the tables needs to be explicitly mentioned to
|
||||
`createPlainTables()` and their corresponding `createSequences()`
|
||||
(you can get them using `\d tablename` from existing DB easily. Then
|
||||
call the `alterTables()` to update the sequence. (I am not sure if
|
||||
`createConstraints()` is required at all, try to remove)
|
||||
- `tearDown()` is pretty easy, just need to call `fullDestruct()`. For
|
||||
debugging, you can add `exit(-1);` after any line you as suspecting,
|
||||
connect to DB and checkout the database, select/inspect tables.
|
||||
- There is also `TestInstaller` class in case any of test case needs
|
||||
the whole mods-enabled with fossology.conf, VERSION, etc. Please
|
||||
check `src/cli/tests/test_fo_copyright_list.php` for quick
|
||||
reference.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Fix the remaining tests.
|
||||
- Add week 8, 9 reports.
|
||||
- Add Final Evaluation Report.
|
||||
- Complete Final Evaluation.

|

In this third meeting, I demoed the working build system, currently building executables and libraries, a lot of queries were resolved about writing version files and attaching commits and hashes to the build.
|
||||
|
||||
## Week 1 Progress
|
||||
|
||||
> This week was mainly focused on analyzing the previous build system and framing a skeleton for the new build system.
|
||||
>
|
||||
> - Created the build configuration [analysis table](https://github.com/avinal/FOSSology/wiki/agents-spec#agents-configuration-list).
|
||||
> - Completed the basic skeleton.
|
||||
> - Completed the CMake configuration for libraries
|
||||
> - To test the current progress, follow the instructions [here](https://github.com/avinal/FOSSology/wiki#test-the-new-system-only-gcc-with-make-and-ninja-tested-for-now)
|
||||
> - Test on [GitPod](https://gitpod.io/#https://github.com/avinal/FOSSology/tree/avinal/feat/cmake-buildsystem) right inside your browser.
|
||||
|
||||
## Discussions
|
||||
|
||||
- **What are the flags needed for C and C++?**
|
||||
- The `-g` flag enables debug.
|
||||
- The `-O2` flag is used for optimizing.
|
||||
- In FOSSology these two flags are used together by default for all
|
||||
build purposes because it is desired to have an optimized binary but
|
||||
some level of debugging information is also desired.
|
||||
- **The Makefiles have some compile-time preprocessor macro definitions
|
||||
that need to be passed to each build.** The Makefiles have all the
|
||||
path values passed as `'"..value.."'` format *(double quote inside
|
||||
single quotes)*, however the commands produced by CMake have
|
||||
`\"..value..\"` format *(escaped double quotes)*. Are they the same or
|
||||
it needs to be changed?
|
||||
- Currently, there is nothing to determine if they work the same or
|
||||
not, but if the compiler would not have accepted them then, it would
|
||||
have thrown an error. As long it is working these should be fine,
|
||||
but will need to be checked in the final build.
|
||||
- **Are all libraries in FOSSology static?**
|
||||
- No, by default no library is static. The format
|
||||
`lib<library-name>.a` is confusing but no need to worry about it for
|
||||
now, if this is working fine then no problem.
|
||||
- In general, this format denotes a static library.
|
||||
- **How to add the version and commit information to the builds?**
|
||||
- I have gone through [this
|
||||
thread](https://cmake.org/pipermail/cmake/2018-October/068383.html)
|
||||
on CMake's official mailing list. And they have suggested a lot of
|
||||
options, but unable to decide which option to use. Gaurav said he
|
||||
will see into this thread and for now, I should try writing a shell
|
||||
script and test if that works.
|
||||
- Same can be tested for the version too.
|
||||
- **What is** `_squareVisitor.h.pre` **used for?**
|
||||
- They are used to generate source code at build time.
|
||||
- **Is there any inheritance structure in the build system?**
|
||||
*(Michael)*
|
||||
- For now, I am writing separate modules for the default operations
|
||||
needed in most configurations. The final structure will be decided
|
||||
in the final build.
|
||||
- **Where are all the binaries produced?** *(Gaurav)*
|
||||
- They are located in the build folder with the same directory
|
||||
structure as the original project.
|
||||
- While installing the same will be used and none of the source
|
||||
folders are ever disturbed.
|
||||
- **Are all flags taken from the Makefiles itself?** *(Anupam)*
|
||||
- Yes and No, there are some flags that CMake uses by default, they
|
||||
can be altered by changing the value for `CMAKE_C_FLAGS` and
|
||||
`CMAKE_CXX_FLAGS`. One can also append their flags. Since not all
|
||||
compilation requires all the flags, I have taken the default one
|
||||
into cache variables, and others are appended while configuring for
|
||||
a particular project.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Try the `monkbulk` in monk and `makefile.sa` in nomos.
|
||||
- Try adding the version and commit hash info.
|
||||
- Implement writing version files for each build.
|
||||
- Add proper comments in the `CMakeLists.txt` files.

## Week 2 Progress
|
||||
|
||||
> This week was mainly focused on creating CMake configuration for libraries, executables and coverage.
|
||||
>
|
||||
> - Added the configuration for libraries and executables
|
||||
> - Resolved parallel build problems with coverage configs
|
||||
> - Implemented generated source configurations
|
||||
> - To test the current progress, follow the instructions [here](https://github.com/avinal/FOSSology/wiki#test-the-new-system-only-gcc-with-make-and-ninja-tested-for-now)
|
||||
|
||||
## Discussions
|
||||
|
||||
- **Should I generalize the coverage build for each agent?**
|
||||
- Coverage depends on the agent_tests and may or may not be available
|
||||
for all the agent. So follow the Makefiles and add the configuration
|
||||
as it is in them.
|
||||
- Leave coverage for them who don't have it already in their
|
||||
Makefiles.
|
||||
- **What are :code:\`\$(AGENTLIB) \$(REPO) \$(DB)\` in the Makefiles?**
|
||||
- They seems to be remains of previous build configuration. Until
|
||||
there is a problem, ignore if you can not find the definitions.
|
||||
- **Can I refactor the directory structure of nomos and monk, it will
|
||||
help keep the source code generation out of source directory?**
|
||||
- Yeah, sure. As long as it does not affects the working of the
|
||||
project you may refactor them to suit your needs.
|
||||
- **I am facing problems with due to headers included using angled
|
||||
brackets, can I change them to double quotes instead?**
|
||||
- Yeah that would be okay, anyway the general practice is to add user
|
||||
header files using double quotes.
|
||||
- **Using -Werror flag in regexscan causes build to fail, should I
|
||||
remove it?**
|
||||
- Since `regexscan` is not the part of default build you can ignore
|
||||
it.
|
||||
- **In scheduler source code the preprocessor macro value for
|
||||
FOSSDB_CONF is different from that in lib, is that correct?**
|
||||
- We have made some changes, please change it to the same as in lib.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Try adding the version and commit hash info.
|
||||
- Implement writing version files for each build.
|
||||
- Add proper comments in the `CMakeLists.txt` files.
|
||||
- Complete the coverage build configuration
|
||||
- Start implementing the install configurations

## Week 3 Progress
|
||||
|
||||
> Version file Implementation
|
||||
>
|

> - Initial functions on obtaining commit and branch info
|

|
||||
|
||||
## Discussions
|
||||
|
||||
- **What is the regex expression used for obtaining version
|
||||
information?**
|
||||
- The regex has recently been modified to cover recent versions. The
|
||||
latest form is as below:
|
||||
|
||||
``` cpp
|
||||
([[:digit:]]+.[[:digit:]]+.[[:digit:]]+)(-?rc[[:digit:]]+)?-?([[:digit:]]*)-?[[:alnum:]]*
|
||||
```
|
||||
|
||||
- You can also try alternatives to regex if possible for CMake.
|
||||
- **Should I use** `git describe --tags` **or**
|
||||
`git describe --always HEAD` **for obtaining version information?**
|
||||
- In FOSSology we always use `git describe --tags`, no exception
|
||||
whatsoever.
|
||||
- CMake provides a preset configuration for the install path on GNU
|
||||
systems, you can see the description
|
||||
[here](https://cmake.org/cmake/help/v3.10/module/GNUInstallDirs.html)
|
||||
based on the
|
||||
[configuration](https://www.gnu.org/prep/standards/html_node/Directory-Variables.html)
|
||||
suggested by the GNU After comparing the variables defined in
|
||||
Makefile.conf with these, it seems directly taken from GNU standards.
|
||||
So I wanted to ask if this would be okay to stick to the presets,
|
||||
instead of manually declaring the same paths? The former step will
|
||||
reduce the number of variables we are currently caching and will make
|
||||
it flexible for different installation scenarios.
|
||||
- Using the GNU standards is the ideal situation but FOSSology uses
|
||||
slightly different locations. For example, all agents end up under
|
||||
`/usr/local/share/fossology/` with their individual folders instead
|
||||
of going to `/usr/local/bin/`.
|
||||
- If the same results can be achieved by using the
|
||||
`CMAKE_INSTALL_<dir>` and `CMAKE_INSTALL_PREFIX` then yeah, it will
|
||||
be preferred.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Try adding the version and commit hash info.
|
||||
- Implement writing version files for each build.

In this seventh meeting question related to installing the FOSSology were discussed.
|
||||
|
||||
## Week 4 Progress
|
||||
|
||||
> CMake configuration files have been refactored to make each agent as a separate sub-project.
|
||||
>
|
||||
> - Symbolic links are installing.
|
||||
> - VERSION files can be generated now during configure step
|
||||
> - To test the current progress, follow the instructions [here](https://github.com/avinal/FOSSology/wiki#test-the-new-system-only-gcc-with-make-and-ninja-tested-for-now)
|
||||
|
||||
## Discussions
|
||||
|
||||
- **There are two types of replacements CMake can configure file with.**
|
||||
`@VARIABLE@` **and** `${VARIABLE}` **. Since in PHP** `$variable` **is
|
||||
used, it may create problem for CMake replacements. So may I replace
|
||||
them?**
|
||||
- Yeah sure, go ahead. It will be more robust.
|
||||
- The replacement of `$VARIABLE` can be stopped by using `@ONLY`
|
||||
option in `configure_file(...)` command.
|
||||
- **How to generate vendor directory?**
|
||||
- The code for generating vendor directory is in `src/Makefile`.
|
||||
- Before executing code for the generation, make sure to copy
|
||||
`composer.json` and `composer.lock` to the target directory.
|
||||
- There is also a patch that FOSSology needs to function as intended.
|
||||
Make sure to run that patch to check and apply.
|
||||
- For now, we generate *vendor* while building, but it would be nice
|
||||
if it can be generated in the build step.
|
||||
- **Currently I am generating the VERSION file in configure step itself.
|
||||
Should I move it to the build or install step?**
|
||||
- Yeah, please move it to the build step. As in configure step the
|
||||
data might be outdated.
|
||||
- **Is there any configuration for Release that we can use to install or
|
||||
test?** *(Michael)*
|
||||
- Yeah, there are 4 inbuilt configurations for various levels of
|
||||
optimization and can be applied to tests and installation.
|
||||
- **Is the VERSION file is generated for each agent or whole project at
|
||||
once? Because in the latter case, the VERSION file can be generated as
|
||||
the last step.**
|
||||
- No agent has a VERSION file along with the main VERSION file for
|
||||
FOSSology.
|
||||
- **How I can build and install a single agent or component?**
|
||||
- There are two ways you can build and install a specific agent or
|
||||
component only.
|
||||
|
||||
- The first one is quite simple. Just change your directory to the
|
||||
specific agent's directory and run all the usual commands for
|
||||
building and installing.
|
||||
|
||||
- The second one is a bit for typing work. This can be used directly
|
||||
from the top-level directory. After configuring the CMake, you can
|
||||
run the following command to install the specific component.
|
||||
|
||||
``` bash
|
||||
# for Unix Makefiles
|
||||
make list_install_component # this will list all the available components
|
||||
cmake -DCOMPONENT=<component-name> -P cmake_install.cmake
|
||||
```
|
||||
|
||||
- I am writing a macro that will let us install a component by simply
|
||||
running `make install component`.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Implement generation of vendor directory.
|
||||
- Move VERSION file generation to build step.

|

In this eighth meeting questions related to post install generation were asked. This was a short meeting.
|
||||
|
||||
## Week 4 Progress
|
||||
|
||||
> Version parsing logic implemented.
|
||||
>
|
||||
> - VERSION and COMMIT_HASH added to every executables.
|
||||
> - Installing part is complete except `cli`.
|
||||
> - Symbolic Links are installing and working fine.
|
||||
> - Version, Symbolic Links, `VERSION` file generation, `version.php` generation are now more modular and called via a single function for each agent
|
||||
> - Most dependencies are now moved to single configuration file.
|
||||
> - Vendor directory generation and installing are now working.
|
||||
> - To test the current progress, follow the instructions [here](https://github.com/avinal/FOSSology/wiki#test-the-new-system-only-gcc-with-make-and-ninja-tested-for-now)
|
||||
|
||||
## Discussions
|
||||
|
||||
- **Why all the symbolic links in cli points to** `fo_wrapper`
|
||||
**script?**
|
||||
- The `fo_wrapper` script calls the PHP script on the symbolic link
|
||||
that called the fo_wrapper. It also initializes any requirement
|
||||
before calling the scripts.
|
||||
- **How to generate all the other configuration in**
|
||||
`/usr/local/etc/fossology` **directory?**
|
||||
- You can find the input files for all these configurations in the
|
||||
`install/defcon` directory.
|
||||
- **What are** `OBSOLETEFILES` **in** `www/ui/Makefile` **?**
|
||||
- They are kept for compatibility purposes. Although they have been
|
||||
removed in the current versions of FOSSology, if a user installs a
|
||||
new version on top of an older instance, then we should explicitly
|
||||
remove those files.
|
||||
- **I have created a separate folder for generating vendor directory. Is
|
||||
that okay?**
|
||||
- Yeah, it should be fine, But it would be better to rename it to
|
||||
something else. Or even better if moved to *www* itself. Since these
|
||||
files are used by www.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Move `vendor` scripts to `www` directory.
|
||||
- Implement installing for FOSSology cli.
|
||||
- Implement installing configuration scripts.
|
||||
- Finish installation for testing

|
||||
|
||||
## Discussions
|
||||
|
||||
- There are permission problems while running bash script of `nomos`,
|
||||
`monk` and `genvendor`.
|
||||
- One possible fix can be to add `bash` before each bash scripts.
|
||||
- The other fix is to modify shebang line in each script from
|
||||
`#!/bin/sh` to `#!/bin/bash`.
|
||||
- In copyright agent same files are being compiled thrice, this is
|
||||
slowing down the build.
|
||||
- I am working on it. The problem is occurring because of three
|
||||
different executables.
|
||||
- I will try to combine the common objects together.
|
||||
- There are some redundant files in the installation. And VERSION file
|
||||
is missing in `/usr/local/share/fossology`.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Fix copyright build.
|
||||
- Remove redundant files and folders.
|

This week I implemented CMake packaging configuration for FOSSology. There were two meetings in this week and this report covers both of them.
|
||||
|
||||
## Week 7 Progress
|
||||
|
||||
> Initial CMake packaging configuration implemented.
|
||||
>
|
||||
> - Packages can be built according to the FOSSology previous packaging structure.
|
||||

|

> - To test the current progress, follow the instructions [here](https://github.com/avinal/FOSSology/wiki#test-the-new-system-only-gcc-with-make-and-ninja-tested-for-now)
|
||||
|
||||
## Discussions
|
||||
|
||||
- **Where I can find packaging info for FOSSology?**
|
||||
- All the scripts and companion files are located inside `debian`
|
||||
folder.
|
||||
- The most important files are `control`, which contains the
|
||||
dependency and description of each package, and `rules` file, which
|
||||
contains the make commands for creating the packages.
|
||||
- **What are** `${shlibs:Depends}` **and** `${misc:Depends}` ?
|
||||
- They are dependencies required for creating Debian packages. CMake
|
||||
should be adding them by default so we can safely ignore them.
|
||||
- **Will the new packages have the same structure as the old ones?**
|
||||
*(Michael)*
|
||||
- Yes for compatibility purposes Gaurav has suggested exactly follow
|
||||
the same structure as the old one.
|
||||
- **Copyright build is slow because the same object files are being
|
||||
compiled three times, can you improve that?** *(Gaurav)*
|
||||
- I can try compiling the common object files beforehand and then
|
||||
adding the executables. But how to know the common object files?
|
||||
- Gaurav showed me where in the Makefiles I can find the common object
|
||||
files.
|
||||
- There are problems with copying the symbolic link and packaging them.
|
||||
So I have to find some alternatives to resolve that.
|
||||
- With component installing, package description can no longer be set.
|
||||
- The `fossology-common` package contains file from `fossology-db`
|
||||
package. And the `fossology-db` package is empty.
|
||||
- Gaurav said this was unexpected and should not happen. This seems to
|
||||
be a very old bug with packaging.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Work more on the packaging.
|
||||
- Improve compilation of copyright and monk agents
|
||||
- Try to solve the packaging bug and add a pull request for that.
|
||||
- Move on to implementing testing configurations.

|
||||
|
||||
## Discussions
|
||||
|
||||
- **How is the testing implemented in FOSSology?**
|
||||
- Not all agents have testing implemented.
|
||||
- There are two types of tests *Unit* and *Functional*.
|
||||
- At first, the test executable calls multiple PHP scripts to create a
|
||||
test environment. And then tests are executed.
|
||||
- Files related to testing and common for all the agents are in
|
||||
`src/testing`
|
||||
- Other tests depends on `phpunit`. This *PHPUnit* is generated inside
|
||||
`vendor`.
|
||||
- **As of now, the testing configurations are hardcoded, what should I
|
||||
do, because it seems the testing configuration will require changes to
|
||||
a lot of files?**
|
||||
- Decide a deadline for the testing configuration and if until that
|
||||
point there is not very productive implementation then move to the
|
||||
next task that is implementing CI.
|
||||
- As of now building, installation, and packaging via CMake is working
|
||||
and in a stable state. To create an initial Pull Request. This would
|
||||
also be useful in case of the final evaluation and further testing
|
||||
will be based on this PR itself.
|
||||
- Fix any bugs or if there is the scope of improvement in Building,
|
||||
Installation and Packaging do that.
|
||||
|
||||
## Conclusion and Further Plans
|
||||
|
||||
- Prepare for an initial PR.
|
||||
- Fix known bugs and apply Improvements.
|
||||
- Work on testing configurations.

|
||||
|
||||
It has been 2 years since I was a Google Summer of Code Student. It was an outstanding opportunity and I really enjoyed working on the project. Not only that, but it added numerous skills to my resume and polished many others. Today I want to make my proposal public, that helped me get selected.
|
||||
|
||||
## Current Build System and Workflow
|
||||
|
||||
### Build System
|
||||
|
||||
FOSSology’s build system is based on multilevel Makefile that work together to
|
||||
provide a build infrastructure for the project. Although make is a robust build
|
||||
system, but it is too outdated and slow compared to modern build systems. Although
|
||||
build configurations are not supposed to be updated as often as source files,
|
||||
there are few noticeable problems with make.
|
||||
|
||||
* Configuration is mostly hard-coded, i.e., if needed to use different tools or add source files, the Makefile needs to be updated
|
||||
* All the dependencies and libraries have to be added manually by writing configuration for each of them
|
||||
* Although the FOSSology project currently supports Linux only, if in the future it has to be ported to other platforms, make won’t be able to support it. Hence, it is not future safe.
|
||||
|
||||
### Workflow (Continuous Integration)
|
||||
|
||||
FOSSology project has been using open-source tier Travis CI for all its continuous
|
||||
integration and deployment needs. GitHub launched its CI/CD system some years ago,
|
||||
and it has become a standard for CI/CD. Travis CI does the work but provides significantly
|
||||
fewer features when compared to GitHub Actions.
|
||||
|
||||
* It has been observed that Travis CI is noticeably slower than GitHub Action for a similar configuration
|
||||
* Travis CI lacks the tight and seamless integration of GitHub Actions with other GitHub Services, some of them are the ability to integrate and communicate with GitHub apps, auto-manage to pull requests and issues, better support for Dockerized builds.
|
||||
|
||||
## Why a New Build System(CMake)?
|
||||
|
||||
There were many possible candidates for a new build system for the FOSSology project.
|
||||
Each has its pros and cons. After numerous comparisons and the ability of the new
|
||||
build system to integrate well with the existing system, CMake seems to be the best
|
||||
choice. Given below is a quick overview of different build systems and their execution times.
|
||||
|
||||

|
||||
|
||||
Here, CMake (Make & Ninja) performs better than average compared to other tools.
|
||||
The criteria for choosing CMake were not only performance, but many other factors.
|
||||
|
||||
* The build system should be easily available on all supported distros - Cmake supports _UNIX, MS Windows (MSVC, Borland, Cygwin, MinGW) and Mac OS X, and more_
|
||||
* It should be easy to install – CMake is available via all popular package managers and repositories
|
||||
* Should improve build speed – In general, CMake always outperforms bare metal make systems.
|
||||
* The learning curve is not too steep – CMake is not very hard and neither too easy to learn. For common projects, it is easy to learn.
|
||||
|
||||
### CMake Perks
|
||||
|
||||
* No other dependencies apart from the C/C++ compiler
|
||||
* Includes a testing framework (CTest)
|
||||
* Includes a multipurpose packaging solution (CPack)
|
||||
* Migrating from Make to CMake is easier compared to other build systems
|
||||
* Can generate platform-specific build configuration; hence the same script can be used for multiple platforms
|
||||
* All modern C/C++ IDEs have inbuilt support for CMake or via a plugin (Visual Studio, XCode, CLion)
|
||||
* Can load dependencies automatically from the internet or local file system
|
||||
* Source and build folders are separate by default in CMake, this avoids bloating the source folders and accidentally deleting important files.
|
||||
|
||||
### Comparison of CMake and Make syntax
|
||||
|
||||
#### Make Syntax
|
||||
|
||||
```makefile
|
||||
CXXFLAGS = -I../include -I.
|
||||
|
||||
SRC := $(wildcard *.cc)
|
||||
DEP := $(patsubst %.cc,%.d,$(SRC))
|
||||
OBJ := $(patsubst %.cc,%.o,$(SRC))
|
||||
|
||||
all: $(PROGNAME)
|
||||
|
||||
$(PROGNAME): $(OBJ) ../lib/$(LIBNAME)
|
||||
$(CXX) $(CXXFLAGS) $^ -o $@
|
||||
|
||||
%.d: %.cc
|
||||
$(CXX) -MM $(CXXFLAGS) $< | sed 's/\($*\)\.o[ :]*/\1.o $@ : /g' > $@
|
||||
|
||||
ifneq ($(filter clean,$(MAKECMDGOALS)),clean)
|
||||
-include $(DEP)
|
||||
endif
|
||||
|
||||
clean:
|
||||
$(RM) $(DEP) $(OBJ) $(PROGNAME)
|
||||
```
|
||||
|
||||
#### Corresponding CMake File
|
||||
|
||||
```cmake
|
||||
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/../include)
|
||||
include_directories(${CMAKE_CURRENT_SOURCE_DIR})
|
||||
|
||||
AUX_SOURCE_DIRECTORY(${CMAKE_CURRENT_SOURCE_DIR} source)
|
||||
add_executable(hellocmake ${source})
|
||||
target_link_libraries(hellocmake LINK_PUBLIC libhellocmake)
|
||||
```
|
||||
|
||||
### How to (c)make the move?
|
||||
|
||||
#### Step 1: Determine the total number and types of Makefiles to migrate
|
||||
|
||||
We will determine the required time for the whole migration and the number of respective
|
||||
CMake scripts to be written. In general, CMake scripts have fewer lines than Make
|
||||
scripts for the same task. However, the top-level CMake configuration can be very
|
||||
complex depending on how many configurations we want to create.
|
||||
|
||||
* There are [168 Makefile](https://github.com/search?q=Makefile+repo%3Afossology%2Ffossology+filename%3A%22Makefile%22&type=Code)configurations as of now in FOSSology Project
|
||||
* Types: Build, Install, Test, Uninstall, Coverage, Clean, Package, and other sister types
|
||||
|
||||
#### Step 2: Start migrating Makefiles one agent/directory at a time
|
||||
|
||||
The FOSSology project’s build system follows a bottom-up approach. That means all
|
||||
the child directories need to be built first to build their parents. Since most
|
||||
of the agents in FOSSology are independent programs, their CMake config can be
|
||||
written separately. I have created a sample project to demonstrate the Make and
|
||||
CMake syntax and build process. It also demonstrates the cross-platform ability
|
||||
of CMake. The project can be accessed here: [https://github.com/avinal/make-cmake](https://github.com/avinal/make-cmake)
|
||||
|
||||
#### Step 3: Create the Top-Level CMakeLists.txt to link all the libraries
|
||||
|
||||
The top-level CMakelIsts.txt will be complex and most of the work, as well as testing,
|
||||
will be done during this phase. In the initial stage, I plan to create just the
|
||||
minimum to at least build the whole project in one go without any bells and whistles.
|
||||
|
||||
#### Step 4: Add required configurations (Install, Package, Test)
|
||||
|
||||
Once the top-level CMakeLists.txt is building the project without any problems.
|
||||
We will now add the required configurations such as install, package, test, uninstall,
|
||||
and other configurations.
|
||||
|
||||
#### Step 5: Test the new Build System
|
||||
|
||||
It is almost done, we may start testing our shiny build system. Checking every
|
||||
single configuration for errors and loopholes. This step will also make use of a
|
||||
new CI/CD system for testing purposes. Thus, simultaneously migrating the CI from
|
||||
Travis CI to GitHub Actions.
|
||||
|
||||
## Improving the CI/CD workflow
|
||||
|
||||
With the new build system, the FOSSology project will get a new CI/CD too. There
|
||||
were several tasks proposed for improving the workflow of FOSSology. I have completed
|
||||
many of them already. Given Below is an overview of the tasks proposed and their status.
|
||||
|
||||
* Syntax Check ([#1919](https://github.com/fossology/fossology/pull/1919))
|
||||
* Static Code Analysis ([#1919](https://github.com/fossology/fossology/pull/1919))
|
||||
* Copy/Paste Detector ([#1919](https://github.com/fossology/fossology/pull/1919))
|
||||
* PHP Codesniffer ([#1919](https://github.com/fossology/fossology/pull/1919))
|
||||
* Docker Tests
|
||||
* C/C++ agent tests
|
||||
* PHPUnit tests
|
||||
* GitHub Page Release ([#1917](https://github.com/fossology/fossology/pull/1917))
|
||||
* Implementing Caching in workflows
|
||||
* Implement source install (reference[#207](https://github.com/fossology/fossology/issues/207))
|
||||
* DOC, Commit, and PR guideline checks
|
||||
|
||||
### How will the workflow improve?
|
||||
|
||||
We are migrating the whole workflow to the GitHub Actions platform, in general,
|
||||
GHA provides better integration and builds time.
|
||||
|
||||
#### Step 6: Migrate the C/C++ agent tests and PHPUnit Tests
|
||||
|
||||
By this time, we have already migrated our build system to CMake and thus the new
|
||||
workflow will be based on CMake configurations. The goal will be to add more platforms
|
||||
(Debian/Ubuntu/Fedora etc.) for tests and upgrade the tools to their latest compatible versions.
|
||||
|
||||
#### Step 7: Implement Source Install test for Ubuntu, Debian, and Fedora
|
||||
|
||||
As of now, source install is not tested for any of the distributions, so this step
|
||||
aims at adding source install testing capability to the new CI.
|
||||
|
||||
#### Step 8: Implement caching in workflows and testing
|
||||
|
||||
GitHub Action can store cache dependencies for a given period and thus reduces the
|
||||
number of times the virtual machine has to fetch packages. This in turn reduces
|
||||
the overall build time as well as reduces the load on servers.
|
||||
|
||||
## Project Deliverables
|
||||
|
||||
* New Build System (CMake) for the project
|
||||
* New Packaging, Install and Test configuration
|
||||
* C/C++ agents tests for multiple versions of GCC
|
||||
* PHPUnit tests
|
||||
* Docker Tests
|
||||
* Cached Workflows
|
||||
* Source installs tests for Debian, Ubuntu, Fedora
|
||||
* Checks for Pull Requests and Commit guidelines
|
||||
|
||||
## Other Deliverables
|
||||
|
||||
* For track my progress as well as a resource for future contributors, I will be writing a weekly/biweekly blog. The same can be used for preparing the final GSoC report.
|
||||
* Since CMake will be new for the FOSSology Community, I will document all the important topics that I will come across while migrating the build system. This will be both a handpicked resource and a reference for future contributors.
|
||||
* I would love to be a part of the community even after GSoC, although the build system and CI/CD doesn’t need to be updated that often, I would like to contribute to other parts of the project.
|
||||
|
||||
## Experience
|
||||
|
||||
I have 3 years of experience in C/C++ programming and one year of experience with
|
||||
CMake and Make. I have used CMake and Make for many of my projects, as well as contributed
|
||||
to other open-source projects. Furthermore, I have created/migrated the CI/CD for
|
||||
many open-source organizations to GitHub Actions, and created many personal projects
|
||||
using GHA as well.
|
||||
|
||||
I have been contributing to many open-source organizations since 2019. I participated
|
||||
as a Technical Writer in the Google Season of Docs 2021 program under the VideoLAN
|
||||
organization. So, I have a nice understanding of open-source project workflow and
|
||||
contribution standards. I am well versed in Git and GitHub.
|
||||
|
||||

## Proposed Timeline
|
||||
|
||||
### Community Bonding (May 17th - June 6th, 2021)
|
||||
|
||||
* Discussing and collaborating with fellow participants and getting familiar with the FOSSology community and projects.
|
||||
* Since CMake is new for our FOSSology community, I will learn and bring in the resources so that people get comfortable with it before the coding period starts.
|
||||
* Going through the codebase and plan strategies for the migration, his includes identification of various types, segregation of libraries, executables, and dependencies.
|
||||
|
||||
### Coding Week 1 (June 7th - June 13th, 2021)
|
||||
|
||||
* Plan the priority order of migration, and create lists for all different configurations
|
||||
* Create CMake configuration for libraries.
|
||||
* There are approximately 8 libraries, since configuration is not that complex, it should take no longer than 1 week to complete
|
||||
|
||||
### Coding Week 2 & 3 (June 14th - June 27th, 2021)🚩
|
||||
|
||||
* If libraries are complete, migrate the agents one by one, since FOSSOlogy is based on a modular architecture, many agents can be independently migrated
|
||||
* There are some 27 agents, 2 agents per day should take 2 weeks; hence I have merged these weeks.
|
||||
* Time may vary for different agents to be migrated to CMake, but on average, this should take 2 weeks.
|
||||
* Buffer Period
|
||||
|
||||
### Coding Week 4 (June 28th - July 4th, 2021)
|
||||
|
||||
* By now all the agents and libraries are migrated and presently the top-level CMakeLists.txt should be created. Since this file will be complex and will need all the child configuration to work, the testing and completion should approximately take 1 week.
|
||||
* This week will also check the overall gains in terms of performance and stability of the new build system.
|
||||
* This is also the minimum requirement for the build system to be said working and to add more configurations
|
||||
|
||||
### Coding Week 5 (July 5th - July 11th, 2021)🚩
|
||||
|
||||
* This week will continue the development of the Top-level CMake configuration.
|
||||
* More configuration will be added for Install, Test, Uninstall, Package
|
||||
* If completed, testing will start and will continue for the next week
|
||||
* Buffer Period
|
||||
|
||||
### Coding Week 6 (July 12th - July 18th, 2021) First Evaluation
|
||||
|
||||
* The build system is a very crucial element of the project; hence it must be tested thoroughly before final rolling.
|
||||
* This week, I will continue the development of all required configuration and testing of the new Build System.
|
||||
* By the end of this week, the new build system will be able to properly build the project and use the configurations, this also marks the end of the first phase and first evaluation.
|
||||
* Buffer Period
|
||||
|
||||
### Coding Week 7 (July 19th - July 25th, 2021)
|
||||
|
||||
* With all the build system working, this week will be used to migrate the CI from Travis to GitHub Actions starting with the C/C++ agent’s test
|
||||
* Now the C++ agent tests will be executed using the new Build System
|
||||
* If completed, then the PHPUnit test migration will start
|
||||
|
||||
### Coding Week 8 (July 26th - August 1st, 2021)🚩
|
||||
|
||||
* Complete the PHPUnit CI migration
|
||||
* Add Docker tests
|
||||
* Start implementing source install test CI
|
||||
|
||||
### Coding Week 9 (August 2nd - August 8th, 2021)
|
||||
|
||||
* Complete Source Install CI
|
||||
* Start implementing workflow caching
|
||||
* Fixing bugs and clearing backlogs
|
||||
* Buffer Period
|
||||
|
||||
### Coding week 10 (August 9th - August 15th, 2021)🚩
|
||||
|
||||
* Checking the build system
|
||||
* Checking the CI/CD
|
||||
* Completing reports and documentation
|
||||
* Update the existing documentation and readme for the new build system and CI
|
||||
|
||||
### Final Evaluations (August 16th - August 23rd, 2021)
|
||||
|
||||
* Code and report submission
|
||||
|
||||
### Milestones 🚩
|
||||
|
||||
1. All agents and libraries have now a CMake build configuration
|
||||
2. Top-level CMake configuration with a stable build
|
||||
3. Top-level CMake configuration with other configs i.e. install, package, test
|
||||
4. C/C++ agent tests, PHPUnit test implemented in CI
|
||||
5. CI/CD is complete according to the task list

## Motivation
|
||||
|
||||
Ever since I came to know about GSoC(that was in my first year), I wanted to be
|
||||
a part of it. This was even before I got the idea of Open Source. Once I started
|
||||
contributing to open source, I started liking it and gradually became a part. I
|
||||
did Google Season of Docs 2020 under the VideoLAN organization and got a nice overview
|
||||
of open-source development, communities, and programs.
|
||||
|
||||
I found that the FOSSology community is very passionate about open-source contributions,
|
||||
and they welcome experts and noobs alike. Other than that, open community meetings
|
||||
are one of the best things I encountered in my open-source journey. I hope by being
|
||||
a part of this community I will exchange skills and experiences and thus help both
|
||||
the community and me.
|
||||
|
||||
## Commitments
|
||||
|
||||
This summer, I don’t have any classes or internships. I found this project very
|
||||
fascinating, and I have already worked out a portion of this project, so this project
|
||||
is my _priority_. Although the program is supposed to be part-time, I will be able
|
||||
to work full time as well on weekends. I will attend all the meetings and prepare
|
||||
reports on time. I am an active member of the community presently, and will continue
|
||||
the streak during GSoC as well as after GSoC.
|
||||
|
||||
**Thanks**
