Until now, the files where the people were meant to change didn't have a
proper copyright notice (for example `Copyright (C) YOUR NAME.'). This was
wrong because the license does not convey copyright ownership. So the name
of the file's original author must always be included and when people
modify it (and add their own copyright-able modifications).
With this commit, the file's original author (and email) are added to the
copyright notice and when more than one person modified a file, both names
have their individual copyright notice.
Based on this, the description for adding a copyright notice in
`README-hacking.md' has also been modified.

Until now, management of the software names and versions in the paper was
done manually (a macro had to be defined in `initialize.mk', then used in
`paper.tex', so they had to be manually set in two places). Managing this
was not easy.
To fix this, with this commit, each software building rule's target is a
text file that contains its human-readable name and its version. In the
end, the configure script sorts them by their name and writes them into a
LaTeX input file that we can easily import as a file into the main paper.
|
|
Until now, these versions were written in each run. This was mainly
inherited from the old days of the pipeline, where we didn't know the
software on the host. But now that we have almost everything under control,
we can just write these LaTeX macros at the end of the configure script and
make `initialize.mk' simpler and also (very slightly!) speed-up/simplify
the processing.

In order to collaborate effectively in the project, even project members
that don't necessarily want (or have the capacity) to do the whole analysis
must be able to contribute to the project. Until now, the users of the
distributed tarball could only modify the text and not the figures (built
with PGFPlots) of the paper.
With this commit, the management of TeX source files in the pipeline was
slightly modified to allow this as cleanly as I could think of now! In
short, the hand-written TeX files are now kept in `tex/src' and for the
pipeline's generated TeX files (in particular the old `tex/pipeline.tex'),
we now have a `tex/pipeline' symbolic-link/directory that points to the
`tex' directory under the build directory.
When packaging the project, `tex/pipeline' will be a full directory with a
copy of all the necessary files. Therefore as far as LaTeX is concerned,
having a build-directory is no longer relevant. Many other small changes
were made to do this job cleanly which will just make this commit message
too long!
Also, the old `tarball' and `zip' targets are now `dist' and `dist-zip' (as
in the standard GNU Build system).
|
|
With this commit, it is now possible to package the project into a tarball
or zip file, ready to be distributed to collaborators who only want to
modify the final paper (and not do the analysis technicalities), or for
uploading to sites like arXiv, or online LaTeX sharing pages.

When building in group mode, users can manage them selves to work on
independent analysis steps and thus not cause conflicts. However, until
now, there was no way to avoid conflicts in building the final paper.
To fix this problem, when we are in group mode, the pipeline will create a
separate LaTeX build director for each user and also a separate PDF file
for each user. This will ensure that their compilations don't conflict.
|
|
Since the current implementation of this pipeline officially started in
2018, all the files only had 2018 in their copyright years. This has now
been corrected to 2018-2019.
|
|
To avoid redundant steps in the the top-level Makefile and make it simpler
and easier to follow, we now define the base names of all the Makefiles in
the `makesrc' variable of the top-level Makefile. `makesrc' is then used to
define the Makefiles to include and the necessary TeX macros at the same
time. This is much more clear and obvious than the previous case were we
had to list the Makefiles and TeX macro files separately in the top level
Makefile.

When there is a problem in creating the final TeX Live installation, the
previous version of the pipeline would not understand and just finish! We
would later have problems in building the paper.
So the following series of steps were taken: to keep the recipes in a
shorter and easier to understand way, the steps to install TeX Live are now
one rule (that produce `.local/bin/texlive-ready-tlmgr' when its
successful), and the steps to install the necessary packages are in another
rule (that produce `.local/bin/texlive-ready' when its successful).
When control comes back inside configure, if `.local/bin/texlive-ready'
isn't there (something failed during the TeX Live installation, or building
packages), then the whole TeX Live installation directory
(`.local/texlive') will be deleted along with the two output files. This
will help ensure that future steps can check the availablility of a working
TeX Live in the pipeline.

Since the final product of the pipeline is a LaTeX-created PDF file, it was
necessary to also have LaTeX within the pipeline. With this commit, TeX
Live is also built as part of the configuration and all the necessary
packages to build the PDF are also installed and mentioned in the paper
along with their versions.
|
|
TeX Live is now also downloaded and built by the reproduction
pipeline. Currently on the basic (TeX and LaTeX) source is built but no
extra packages, so the PDF building will fail. We'll add them in the next
commit.
|
|
The system's environment is now removed from the internal processing of the
pipeline, except for LaTeX.
|
|
To enable easy/proper reproduction of results, all the high-level
dependencies are now built within the pipeline and installed in a fixed
directory that is added to the PATH of the Makefile. This includes GNU Bash
and GNU Make, which are then used to run the pipeline.
The `./configure' script will first build Bash and Make within itself, then
it will build
All the dependencies are also built to be static. So after they are built,
changing of the system's low-level libraries (like C library) won't change
the tarballs.
Currently the C library and C compiler aren't built within the pipeline,
but we'll hopefully add them to the build process also.
With this change, we now have full control of the shell and Make that will
be used in the pipeline, so we can safely remove some of the generalities
we had before.

While trying the checklist, I noticed that I had forgot to add my name
after the copyright year and that `reproduce/src/make/paper.mk' still had
my own name on it, the copyright notice also said `script' instead of
`Makefile' which is now corrected.
|
|
To be more generic (and avoid listing file names in `README.md'), a command
is now used to find the files where the name has to be added to the
copyright notice. Also, I noticed that `reproduce/src/make/paper.mk' lacked
a placeholder name/email, so one was added.
|
|
The comments needed to be corrected to fit and explain the new logic (LaTeX
being run within another directory).

Making plots and including references are integral parts of a scientific
paper. Therefore to demonstrate how cleanly they can be used within the
pipeline, they are now used to produce the final PDF.
To use PGFPlots a random dataset is made (using AWK's random function) and
is plotted using PGFPlots. The minimum and maximum values of the dataset
are also included in the text to further show how such calculations can go
into the macros and text.
For the references, the NoiseChisel paper was added as a reference to cite
when using this pipeline along with the MUSE UDF paper I, which uses this
pipeline for two sections. Following this discussion, citation is also
discussed in `README.md` and the NoiseChisel paper is also added as a
published work with a reproduction pipeline.

Until now, the copyright statement was left empty for the users of the
pipeline to fill. However, the files have already been created and have an
author (or contributing authors) before the user starts using the
pipeline. So the original authors of the files are added along with the
year. The user can add their own name to the existing files under the
"Contributing author" when they start and they will be the "Original
author" of the new files they create.
Several changes were also made to the TeX management:
- LaTeX is run within a `reproduce/build/tex/build' directory now. Not in
the top reproduction pipeline directory. This helps keep all the
auxiliary TeX files and directories in that directory and keep the top
reproduction pipeline directory clean. After the final PDF is built, a
copy is put in the top reproduction pipeline directory for easy viewing.
- The PGFPlots preamble was also made more useful, allowing the name of
the `.tex' file to also be the name of the final plot that is
produced. This is a GREAT feature, because without it, the TiKZ
externalization would be based on order of the plots within the
paper. But now, order is irrelevant and we can even delete the TiKZ
files within the processing workhorse-Makefiles so the plots are
definitly rebuilt on the next run.
- The paper is now in a two-column format to be more similar to published
papers.
A tip on debugging Make was added to `README.md'.

Let's start working on this pipeline independently with this first
commit. It is based on my previous experiences, but I had never made a
skeleton of a pipeline before, it was always within a working analysis.
But now that the pipeline has a separate repository for its self, we will
be able to work on it and use it as a base for future work and modify it to
make it even better. Hopefully in time (and with the help of others), it
will grow and become much more robust and useful.
