To enable easy downloading of HTTPS links with Wget (this pipeline's defaut
downloader), we need a set of trusted CA certificates. Until the time that
we can generate one ourselves, one generic set of trusted CA certificates
is now downloaded like a tarball and placed in the OpenSSL configuration
directory.
With these CA certificates, within the pipeline we can now safely use the
pipeline's own installed Wget.
|
|
Some high-level programs like Wget and cURL need to be built in shared mode
because they also include dynamic loading of libraries. Therefore, if we
only build the lower-level libraries in static mode, our own build will be
ignored and they will go and find the system's shared libraries to link
with. Because of this, for now, we have manually set the `static_build'
variable in the configure script to `no'.
Also, if the downloader fails, we'll delete the output (an empty file in
the case of Wget) because it interefers with a target definition.
|
|
The TeX Live installer needs Wget to operate smoothly, especially on recent
Mac OS systems that don't have Wget pre-installed. Also, it would be good
for the pipeline to have its own downloader. So with this commit, the
pipeline also installs Wget and OpenSSL which is a dependency.
Many other small changes/fixes were done in this process.
|
|
Thanks to the check by Cristina Martínez, some corrections were made when
we attempt to download and install TeXLive. Further checks and corrections
will be in due time.
|
|
Until now, we were downloading TeX Live's tarball within the same rule that
unpacked it. But this causes problems for situations were it cannot be
downloaded within the pipeline (and manually placed in the tarball
directory). So now, the TeX Live downloader is treated like all the other
downloaders.
|
|
The main reason I wasn't using cURL as a downloading tool was that I wasn't
familar with how to ask it to follow a re-direct. But I just found out that
its with the `-L' configure time option. So it is now added as a downloader
tool to the pipeline.
|
|
On the Libgit2 webpage, it has recommended to build it statically on Mac
systems. By default we are doing this on Linux systems, but the `-static'
flag failed on Mac. But apparently CMake might be able to deal with the
issue in a different way.
|
|
While testing on another computer, I noticed that to operate properly, the
file given to `flock' must be created before it is called. This is a
low-level difference (how the system treats files), so it wasn't apparent
on my system. To fix it, we have added a `touch' command before it.
|
|
There was an extra `$(lockdir)' target in `download.mk'. This has been
corrected.
|
|
Thanks to a test build on Raul Infante Sainz's Mac OS computer, we were
able to address some issues and will be trying them after this commit:
a) The LLVM linker on that computer didn't recognize `-rpath-link'! So at
configure time we now check for it and only include it when the linker
recognizes it.
b) CMake corrections: 1) `CMAKE_LIBRARY_PATH' is now defined so CMake can
look in our custom directory to find the necessary libraries. 2) To
build and install the CMake built programs, we now simply use `make'
and `make install'.
c) To avoid particular linking problems with WCSLIB (which has special
problems compared to other libraries), we are now deleting the shared
library version (both on GNU and Mac systems).
|

GNU Binutils (which provides the GNU Linker) is not ported to Mac OS
systems. GCC also takes a very long time to build, and if we are to still
have linking problems with LLVM's linker, it would be better to just ignore
GCC also and use the system's C compiler and linker together.
So for the time being, GCC isn't a main target of the basic dependencies
and won't be installed. But we have kept the rules that were checked on a
GNU/Linux operating system.
|
|
Previously the SHELL environment variable was only set in `./configure',
`make', and `make install' after our internal Bash was installed. This
caused problems with Lzip's configure script on older shells (tested on a
Mac OS by Raul Infante Sainz).
So now, before having our own Bash, we set it to a possibly existing Bash
on the system and if that isn't present, just the standard `/bin/sh'.
|
|
The pipeline now installs GCC and all its necessary prerequisites.
|
|
The linker of LLVM version 10.0.0 (clang-1000.11.45.5) doesn't recognize
the `-rpath' linker option! After some searching, apparently it does
recognize `-rpath-link' so we are testing with that now.
|
|
Until now we weren't explicity writing the full path of the dynamic
libraries necessary for linking a program. But now with
`-Wl,-rpath=$(ildir)' we ensure that the linker keeps the address of the
dynamic libraries necessary for linking at linking time, not running
time. Also, `pkg-config' is also built when preparing the basics. Several
other minor corrections were made thanks to the great help of Raúl Infante
Sainz.
|
|
We had forgot to add the rule to build the lock file directory for
downloading data. This has been corrected.
|
|
The high-level dependencies are now built without having access to the
system's PATH. To do this, all the necessary software that we aren't
building ourselves are now brought into the installed `bin/' directory
using a symbolic link to the corresponding software on the host. To do
this, it was also necessary to increase the number of basic/low-level
packages that we are building, and add several more (Diffutils and
Findutils).
With this process in place, we now have a list of the exact software
packages that we are not building our selves, enabling easy building of all
such dependencies in the future.
|
|
While working on a research project using this pipeline, I noticed that we
don't have any `sh' executable within our PATH. However, some programs
(including Gnuastro's configure script, when it is checking for shells to
use with Libtool) check and use it. So after building Bash, we also build
an `sh' symbolic link to point to the built Bash executable.
|
|
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.
|
|
Until now, we were keeping the input file within the reproduction
pipeline's directories using the same name as the database/server. Now, we
are using a short/summarized filename convention for the input dataset.
|
|
In most analysis situations (except for simulations), an input dataset is
necessary, but that part of the pipeline was just left out and a general
`SURVEY' variable was set and never used. So with this commit, we actually
use a sample FITS file from the FITS standard webpage, show it (as well as
its histogram) and do some basic calculations on it.
This preparation of the input datasets is done in a generic way to enable
easy addition of more datasets if necessary.
|
|
A new version of the ghostscript package is now available, so the used
version in the pipeline (previously 9.25) has been incremented to 9.26.
|
|
When you point to this project, the `README.md' file is the default file
that opens on GitLab and other online git repositories. Since a
reproduction pipeline project is different from the actual pipeline, its
best for the default text that opens to describe the paper, not the
pipeline. The old `README.md' is also kept, but its now called
`REAME-pipeline.md'.
|
|
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.
|
|
The system's libraries are no longer used in building the higher-level
dependencies. Also, thanks to Raul Infante Sainz, we found out that Bash's
build script was still removing the extra directory information (not
good!).
|
|
GNU Coreutils are basic programs that can help in the configuration of
higher-level programs. Because of that, it was a dependency of almost all
software built in `dependencies.mk'. To make things more clear, easier to
read and faster (when building in parallel), the building of Coreutils is
now moved to the `dependencies-basic.mk' rules. There, it is built
along-side Bash. Since `dependenceis-basic.mk' is run and completed before
`dependencies.mk', with this, we can be sure that Coreutils is present by
the time we want to build the higher-level programs.
Also, Zlib is now added as a dependency of Git also (it is necessary for
its build).
|
|
Until now, we were building Libtool as a high-level `top-level-programs'
software. But all tools that use the `./configure' script already have a
version of Libtool in them. So ultimately the `libtool' in the PATH is not
used. However, in the case of Gnuastro, we need libtool for running
BulidProgram. So in effect, its a dependency of Gnuastro.
|
|
When the C compiler is not GNU GCC, linking with GNU Binutils is going to
cause problems. So until the time that we can include GCC into this
pipeline, its best to avoid Binutils also.
Also, for building CMake, we were relying on an installed CMake, but now,
we are using its own `./bootstrap' script, so it can be built even if the
host system doesn't have CMake.
Also, for TeX Live, we are now setting a custom file as main target to
avoid complications with symbolic links as targets in Make.
Finally, when the user says they don't want to re-write an existing
configuration file, no extra notices will be printed and the configure
script will immediately start building programs.
|
|
After going through the checklist for starting a new project based on the
pipeline, I noticed some parts that could be modified to be more
clear. They are now applied.
|
|
Until now, we were using a customized `tar.lz' tarball for Gzip. But on
systems that don't have GNU Tar, this will cause a problem (non-GNU Tar
doesn't recognize `.tar.lz'). So to keep things simple, we are using the
customized gzip in `tar.gz' format. After the internal build of GNU Tar and
Lzip, the default method of unpacking (`tar xf XXXXX.tar.XX') will work
nicely on all the standard compression algorithms and we don't have to
modify our commands based on the algorithm (nice feature of GNU Tar).
|
|
The two README files have been updated to explain the new feature of
downloading and building dependencies.
|
|
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.
|
|
If the Makefile `$(static_build)' variable in
'/reproduce/src/make/dependencies-build-rules.mk' isn't defined (by
mistake), it will default to blank space, then the Shell will complain
about a bad formatted operator (needing two operands). So an `x' was added
before it and before `yes' which will allow us to safely pass such cases
without a terrible crash.
|
|
The default Mac compiler has problems building static libraries. Since we
are not yet building the GNU C Compiler as part of the pipeline, we'll have
to rely on the host system's compiler. Therefore, a check is now added a
the start of the configure script that will build a minimal program with
the `-static' flag and if it fails, it will print a warning. Afterwards,
none of the dependencies will be built with the `-static' flag.
|
|
A semi-colon was missed in defining the link for `zlib'. It is now added.
|
|
To have better control over the build, GNU Binutils, Bzip2, GNU Gzip, and
XZ Utils have also been added to the pipeline. Some other minor cleanups
and fixes were also implemented throughout the process.
|
|
Until now, when a package was to be built statically, we were adding the
`--static' option to `CFLAGS'. This was the wrong place to put it! It
should be in the linking step (thus `LDFLAGS'). Also, based on Bash's
configure script, we are now using the more generic form of `-static'
(single dash, not double dash).
On the other hand, the `--disable-shared' option isn't available in many of
the packages and it is highly redundant with the `-static' option, so it
has been removed to avoid an extra warning in such packages.
|
|
To ensure the easy unpacking and building of the programs, Lzip and Tar are
now also build during the initial setup phase.
Some minor corrections were also applied to make things cleaner and
smoother.
|
|
Until now, we used semicolons in Make's Call function definitions to build
the programs with GNU build system or CMake. Therefore, if any step of the
process failed, the rest would be ignorant to it and pass. Now, we use `&&'
to separate the different processing steps. In this way, we can be sure
that if any of them fails (during configuration, or building for example),
the pipeline will also stop and not continue to the next command (in the
same recipe).
Since the two Make Call functions were identical in the two
`dependencies-basic.mk' and `dependencies.mk', they are now in one file to
be imported in both.
This bug was found by Raul Infante Sainz.

After a test by Raúl Infante Sainz, we found out that the configure script
and the Make script for Bash and Make are making too many assumptions on
more recent versions of both. As a result, it couldn't be built.
Therefore, the `configure' script was modified to not use more recent tools
like `readlink' (to find the absolute address of a relative one). It was
also re-organized to not have to read the configuration parameters from a
text file. The parameters are directly read from the command-line and are
written into the proper file afterwards. This removes the need to opening a
text editor by the user (which also caused problems on Raúl's system).
To fix the Make version issue, the building of Bash and Make are now done
in a new Makefile (`reproduce/src/make/dependencies-basic.mk'). This file
doesn't make many of the assumptions that were made in
`dependencies.mk'. So it should hopefully work on any version of Make.
To help in debugging, for now, the Makefile of configure, are asked to work
on one thread (the `-j' option is commented in the `configure'). But after
checks, we'll fix this.
|
|
All the libraries that define their version string as a macro in their
headers are now also checked in `reproduce/src/make/initialize.mk'.
Also, the CFITSIO tarball now follows the same versioning style as the rest
of the tarballs: a script is added to convert the version string into what
is included in the tarball.
|
|
The version of all programs is now checked in
`reproduce/make/src/initialize.mk' and the pipeline won't complete if any
of the program versions change from those listed in
`reproduce/config/pipeline/dependency-versions.mk'.
Since the pipeline is systematically checking all program versions, we
don't need Gnuastro's `--onlyversion' option any more. So it (and all
references to it) have been removed.
|
|
The system's environment is now removed from the internal processing of the
pipeline, except for LaTeX.
|
|
We were mistakenly using GSL's name for the unpacked tarball.
|
|
During the configuration step several new programs that were necessary for
a more complete controlled environment are now also downloaded and built
statically.
|
|
The host web address of most of the necessary packages was blank (filled
with `WWWWWWWWWWWWWWWW' as a place holder). They now point to the correct
webpages.
|
|
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.
