  • 2023-09-15 #281 Rename net.splitcells.network.worker to net.splitcells.network.worker.via.java. It is required for a new net.splitcells.network.worker project. This new project will integrate different implementations of the network worker and provide a common interface for that. Different implementations are required in order to support worker tasks for different environments. For instance cloning and updating all repos in different contexts. A build server needs to be able to update its repos via native programs for bootstrapping the build, but requires integration code for the used operation system. A Java based server instance running with a copy of the repos can updates its repos via Java code, without requiring any additional native programs. The Java based server is more portable as the build server with the bootstrapping build.
  • 2023-09-15 #281 Create dedicated project for a project files standard:
    1. This project moves all such files to one dedicated place and thereby creates a standard, that is easier to understand, support and check.
    2. Some files were moved from the root project and projects/net.splitcells.os.state.interface to projects/net.splitcells.project.standard.

  • 2023-02-12 #218 Relicense main repo to EPL-2.0 with GPL-2.0-or-later as a secondary license.
    1. This was done, because EPL-2.0 OR MIT was planned as an transitioning licensing, until EPL 2.0 with GPL-2.0-or-later as the secondary license (EPL-2.0 OR GPL-2.0-or-later) could be adopted. Before this change it was assumed, that EPL-2.0 OR GPL-2.0-or-later requires dependencies to be compliant with GPL-2.0-or-later at all times. It was later found out, that GPL-2.0-or-later compliance seems to be only relevant, when work is actively made available under the secondary license GPL-2.0-or-later and this only has to be done by the distributor.
    2. Create licensing guidelines.

  • 2022-02-28: #125: Create and add CommonMarkChangelogEventRenderer to the web server in order to extract events from one changelog file. For every supported path [...}/CHANGELOG.html there is now an appropriate supported path [...}/CHANGELOG.events.html.
  • 2022-02-25
    1. Create command repo.copy. It makes the repo.clone* commands more usable, by providing useful options and making it easy to combine said flags. For instance, in order to ensure that a folder contains a repo one can use the following call: repo.copy --target-folder=. --omit-if-exists=true --remote-repo='<URL of remote repo>'. I do not know, if this is better than repo.exists || repo.clone.into.current '<URL of remote repo>'. It may be the case, because additional checks can be added more easily this way, without changing existing code, but I am not quite sure. On the other hand, this is also a way to document the expected use cases of a tool and can be used as a guide, informing the user how to use the software.
    2. #142:
      1. Define rootPath option to web server config.
      2. Translate links according to the rootPath config, which is / by default. If / is used as rootPath, then the path translation does not change the path. For instance, /net/splitcells/gel/index.html is translated to /net/splitcells/gel/index.html in this case. If rootPath is set to /net/splitcells/martins/avots/website/, then it is translated to /net/splitcells/martins/avots/website/net/splitcells/gel/index.html.
  • 2022-02-23 #s69: Rename Renderer class names in order to unify naming:
    1. CommonMarkChangelogExtension -> CommonMarkChangelogRenderer
    2. CommonMarkReadmeExtension -> CommonMarkReadmeRenderer
  • 2022-02-23
    1. #s69 Create easier to navigate alternative to local path context in website: The default layout for the website contains now a Relevant Local Path Context section in the secondary content column. It is located right before the Local Path Context and only lists paths, that are relevant for ordinary users. The new section makes it easier to navigate between the different pages of the site.
    2. #s69: The web server's renderers now have a concept of a relevant path layout. Other than the regular path layout, it contains not all supported path of the web server. The relevant layout contains a subset of the regular layout and focuses on the paths, that are relevant for the normal users.
  • 2022-02-22 #s72:
    1. Remove unused class net.splitcells.website.server.project.Location.
    2. Define config class, in order to pass additional or configuration info to renderers and server.
    3. Add config parameter to ProjectRenderer#renderHtmlBodyContent, Renderer#renderFile and Server.
    4. Move validators of net.splitcells.website.server.* to net.splitcells.website.server.project.validator, in order to improve code structure overview.
    5. Use /net/splitcells/website/server/config/layout.xml inside XSL scripts for the file layout file. This way, multiple XSL scripts for different webserver configurations are not needed. The layout file is also not stored in the file system anymore and is queried from the new Config class. Thereby the number of different locations for the webserver is reduced.
  • 2022-02-21 #142 Remove net.splitcells.website.html.content project. It was an alternative minimal style for the website. It is now integrated into the default style and can be enabled via the generated.style option and the value minimal. For this the RenderingConfig class was created and is used by ProjectsRenderer. The standard styling is too complex. Using one unified style with switches makes it easy to recognize the complex parts and to migrate these to simpler forms. Furthermore, maintaining 2 styles that are mostly identical is costly.
  • 2022-02-20: Move package.install implementation for rpm-ostree from OS state interface lib, to the OS state interface lib GPL 2.0, because rpm-ostree contains GPL 2.0 code.
  • 2022-02-20: Fix syntax errors in system.ssh.server.require and system.ssh.server.require.
  • 2022-02-17: #8: Make argumentation rendering in Gel less verbose for optimization solutions. This makes it easier to understand errors in solutions by omitting the excessive usage of the word argumentation.
    1. Every Constraint#naturalArgumentation method now returns an optional perspective. Thereby, the number of nodes in the AST of the argumentation is reduced.
    2. The usage of the word argumentation itself was greatly reduced. Before the change an argumentation would look like the following:
      Argumentation For all rail
      Argumentation Argumentation Then values of allocated hours should have the same value
      Now it looks like this For all rail Then values of allocated hours should have the same value.
  • 2022-02-15: Comment On Generic Allocators Fourth Version (Gemini Link)
  • 2022-02-14: #138 Create developer introduction:
    1. An introduction to the constraint system was created. It shows how to model and solve the N queen problem on a conceptional and source code level.
    2. The performance of Gel was improved as well by 5 times, because the runtime for solving the N queen problem was completely unacceptable. The original runtime for the Backtracking algorithm was 65 seconds and was improved to about 25 seconds. This is still a lot, but somewhat bearable as one (hopefully) would not make a new coffee in that time.
    3. There are also now 2 new repositories in order to avoid data bloat in the main repo:
      1. net.splitcells.network.log: This is used as a public repo for logs like performance data or the execution time of project tasks.
      2. net.splitcells.network.media: Contains media files like SVGs.
  • 2022-02-14: #138 Create developer introduction.

    2. #s68: Create repo for media files: This repo is named net.splitcells.network.media and is a peer repo to this repo cluster.
  • 2022-02-11:
    1. Fix source code error in user.ssh.key.authorize, which prohibited its execution.
    2. Simplify and generalize detection for Fedora based systems with DNF in system.ssh.server.start. This makes this script also workable on Fedora Silverblue.
  • 2022-02-10: JPG images served by website server's resource extension now get the correct content type.
  • 2022-02-07: #43: Ensure at least 30% test coverage.
  • 2022-02-07: SVG images served by website server's resource extension now get the correct content type.
  • 2022-02-05:
    1. #163: Create repo.push.at as the new version of repo.push.to:
      1. Deprecate repo.push.to, because it uses positional arguments and therefore understanding argument meaning gets hard. The command also only supports remote IDs and not URLs. The positional argument parsing makes it hard to add simple features. The deprecated commands signals this with an error message, but works otherwise.
      2. Create command repo.push.at, that uses only classical Unix style argument handling. Support for pushing to URLs was added as well.
    2. #10: Create generation.style variable for default XSL style for multiple output style configuration.
    3. #10: Integrate JaCoCo report into website via an additional renderer.
  • 2022-02-04: #s68: Add peer repository net.splitcells.network.media to website.
  • 2022-01-31: Make test coverage via codecov.io public. It can be seen on the README.
  • 2022-01-30: Remove all additional commands in user.start like user.configure, because this makes the command too complicated and it also makes it too hard to maintain backwards compatibility.
  • 2022-01-30: Create command world.manage, that calls all configuration and update commands provided by OS state interface. Thereby, the user can check, if all possible configurations and updates are applied. This also acts as a central documentation for all configuration and update commands of the OS state interface project. This command adds the new concept of a world in the context of the user, system and network concepts. The world contains and represents all top level concepts and therefore is a representation of all accessible objects.
  • 2022-01-23: Create command flatpak.gui, in order to easily find Flatpak's default GUI based application manager.
  • 2022-01-23: #43 The default XSL style sheet for the website does not convert the layout links for the local path context anymore. The conversion was introduced as a hack in order to compensate for other bad code. It converted paths for XML files by replacing the XML suffix via an HTML suffix, which made the links invalid.
  • 2022-01-23: #138: LinearDeinitializer now correctly selects the allocation of a supply.
  • 2022-01-23: #s27: Fix local path content for rendering of text files.

  • 2022-01-09: #138: Make default values of StaticFlags more reasonable performant.
  • 2022-01-09: Remove run.and.print.only.errors.sh and run.and.print.sh, because there are too many run.and.* commands, that are not used and are too similar. This makes it unjustifiable hard to choice a fitting run.and.* command.
  • 2022-01-09: #148: Fix local path context for rendered XML files in website server.
  • 2022-01-05: #138 Create project net.splitcells.gel.quickstart. It is a minimal project, that demonstrates how use the Gel framework. It can also be used as a template for new projects.
  • 2022-01-02: #138 Fix user command rendering via UserCommandRenderer by rendering command tree with http://splitcells.net/den.xsd namespace.
  • 2021-12-31: #138 The website server now supports via the LinkTranslator links from CommonMark files to other files located at other projects, instead to other files of the same projects.
  • 2021-12-28: #s44 The Domsole now filters log messages with a lesser priority than INFO by default. This behaviour can be overwritten with the Option MessageFilter.
  • 2021-12-27: #s44 Create first draft of HTML link Validator based on heuristics regarding HTML parsing, so that a framework does not need to be included.
  • 2021-12-27:
    1. #s44:
      1. Restore rendering of stack traces for logging in Domsole (see Ui#append).
      2. Fix warning in webserver caused by UserCommandRenderer#projectPaths. This method now correctly provides its managed project paths.
  • 2021-12-26: #s44 Rename Validator to SourceValidator in order to clarify purpose, because a validator for rendered files via the web server is needed.
  • 2021-12-23: #138 CSV rendering via chart.js now renders the requested csv file. Previously, this renderer always rendered the same file, regardless of the request
  • 2021-12-23: The supply selector had a probability to throw an exception, if there are freed supplies given an optimization event list, but no free supplies are present before applying the optimization event list to a given solution. If there are no free supplies present, freed supplies are used by the supply selector instead.
  • 2021-12-20:
    1. Create command ssh.execute.in.background in order to start background tasks on remote servers with systemd and ssh.
    2. Create command system.lock, that locks all input and output devices of the system users' (i.e. lockscreen).
  • 2021-12-19: #138 Create rating cache for constraints via ConstraintAspect. In the future, it may be implemented in such a way, that it may be disabled. This is easy to implement, because this feature is implemented as an aspect.
  • 2021-12-19: repo.synchronize.with now uses the new interface of repo.repair, which got a breaking change previously in order to improve and standardize argument parsing.
  • 2021-12-16: The rating methods of the constraint interface now only return ratings instead of meta ratings, in order to increase runtime performance. Meta ratings have a higher overhead than primitive ratings, because these are wrappers around primitive ratings based on a lookup map. In most common optimization problems and also for simple problems in general, meta ratings are not required. Supporting this common case explicitly, yields performance gains. Meta ratings can be still obtained via the asMetaRating method of ratings.
  • 2021-12-13: #132 Justify current bias toward online optimization.
  • 2021-12-12: The command repo.repair was rewritten in Python in order to support better argument parsing, which has a relatively complex syntax in Bash. The implicit argument (no flag required for setting) was converted to an explicit argument (--remote-repo=[...]. The command now also accepts one value for this argument, because multiple ones do not make sense.
  • 2021-12-11: #138
    1. Add net.splitcells.network.log to website's default projects. This is a new git repository containing log files. These files are primarily performance data and are used in order to show performance regressions.
    2. Create CSV serving and rendering of CSV files as charts to website server (CsvRenderer and CsvChartRenderer). This is used in order to create a simple visualization of the new repository.
  • 2021-12-10: #138 Remove temporary duplicate assignments during HistoryI reset, in order to improve performance.

  • 2021-12-05: Ordered#compare_to now does not always double-check equality.
  • 2021-12-04:
    1. #138: Replace net.splitcells.dem.environment.config.StaticFlags.PROFILING_RUNTIME with PROFILING_METHOD_STATISTICS. The former one was deprecated, because it was not used and its intent was not clear. The latter one was introduced, because its usage is quite clear. Note that generic static flags are not that useful, because by enabling a generic one, many additional runtime tasks may be activated, which may destroy the software's performance.
    2. #138: Rename package net.splitcells.dem.resource.host.integration to net.splitcells.dem.resource.communication.log. The reason for this, is the fact, that the shell may not be on the host computer.
  • 2021-12-03: command.managed.execute now uses shutil.which instead of distutils.spawn.find_executable, because the latter one is deprecated and will be removed from Python with the version 3.12.

    3. #s26 Support arbitrary renderers for website server:
      1. Details are described in the network's blog.
      2. Create OS State Interface command project.render, in order to define a primitive unified building API for different build systems and projects.
      3. Create command project.render.as.net.splitcells.website in order to support arbitrary website renderers. This is currently used in order to deploy the network's blog, my private website and the network's website as one website. Linking between the network's blog and the rest of the site is currently lacking.

  • 2021-11-08:
    1. #26 Create command project.render.as.net.splitcells.website as an API for creating plugins for splitcells.net's website server built out of software, which have no explicit integration for said website server. Integration is done by reading or writing to the same filesystem. In order to create a plugin following needs to be done:
      • Add and implement the following executable at a project: ./bin/render.as.net.splitcells.website.to. It takes one argument containing a path. The command needs to write the plugin's part of the website to that path.
      • Add the following to the website's build script:
        • cd <plugin's path>
        • project.render.as.net.splitcells.website
    2. #s24 Deprecate usage of CommonMark as the main documentation format: CommonMark is now only supported on second level. Sew XML is now the primarily supported format for articles. The source type guidelines were updated accordingly.
  • 2021-11-06:
    1. #10 Rename net.splitcells.dem.data.order.Comparator.comparator_. to comparatorLegacy in order to have a clear name and remove its usage, where it is not needed.
    2. #10 Rename net.splitcells.dem.data.order.Comparators.comparators to comparator in order to unify naming.
  • 2021-11-05: system.update for Flatpak now does not exit with an error, if Flatpak's version itself is deprecated. This is done because otherwise the whole update process would be aborted. An appropriate echo to stderr is created instead.
  • 2021-10-31: #110 Register extension path via extension instead of duplicate code: Remove deprecated ProjectsRenderer#projectsLayout method and use ProjectsRenderer#projectsPath instead. This new method is a lot easier to implement than the precursor, especially if future extension may be implemented via third party software.

  • 2021-10-25 #90 Fix deployment of CommonMark files: Before the patch CommonMark were not rendered and uploaded via the website server.
  • 2021-10-22 command.managed.install now removes the file suffix of the source file, when installing the command as a dependency. Previously this was only done for the API defining commands. For example: the Ossi project has the command repo.push.sh, which uses dependency injection in order to do its job. This command is installed to ~/bin/net.splitcells.os.state.interface.commands.managed/repo.push. Note the stripped file suffix in order to have a name, that is not specific to the implementation (this behaviour was already present before the implementation). Another file provides the implementation for Git repositories and is named like the original command + its implementation specific file suffix. Let's say repo.push.sh. Before the patch the file suffix would not be removed and the file would be installed to ~/bin/net.splitcells.os.state.interface.commands.managed/repo.push.sh.0. This would lead to an error, during the execution of repo.push, because the dependency repo.push.0 would not be present. After the patch the file is installed to ~/bin/net.splitcells.os.state.interface.commands.managed/repo.push.0.
  • 2021-10-19 #s7: Fix CI timeout on sourcehut. user.ssh.key.generate.sh causes a timeout on the build job for FreeBSD. This was caused by the fact, that the file location and the password were set by sending newline symbols via the echo command and a shell pipe to the ssy-keygen command. The echo command was used in a non POSIX way, which fails on the new FreeBSD release. This patch sets the file location and password via flags provided by ssh-keygen.

    1. Delete the interface net.splitcells.dem.resource.communication.Subscribable, because it was not used.
    2. Make package structure more consistent.
      1. Move Dem's Files interface from communication package to more general resource package.
      2. Move Dem's LogMessage, LogMessageI and LogLevel from the package net.splitcells.dem.resource.communication.interaction to net.splitcells.dem.resource.host.interaction, because sees interfaces and classes are not host specific.
    3. Rename net.splitcells.dem.lang.annotations.Return_this to ReturnThis in order to unify naming.
  • 2021-09-17: #10 Introduce the first pure project: net.splitcells.dem.merger
  • 2021-09-15: #8 Migrate Domsole from XML node base to Perspective base. Thereby, a custom rendering format is created, which is more suitable for the console, as it is a lot shorter, simpler and nicer. The XML rendering is currently broken and will be fixed for the website, when it is used again. Logging based on XML nodes is removed, also some deprecated method still exists, but they have no functionality.

    1. Create concept presentation for Gel based on thought experiment.
    2. Support serving raw HTML files via webserver.
    3. Render changelog on website.
  • 2021-09-11: run.and.show.if.failed now echos content of stderr to the shell during the execution normally. This way one knows all the errors, that appeared after a successful execution of the given command. If for instance one has a data synchronization script for multiple backup servers, one can see which server could not be reached, without marking the whole execution as failure.
  • 2021-09-11: Support Fedora Silverblue, by implementing package.install via rpm-ostree. This package install command has the highest priority, because package managers like dnf should be ignored in this case.
  • 2021-09-05:
    1. Disable caching for default weblayout in order to keep CSS styling in webbrowser up to date.
  • 2021-09-04:
    1. Create command user.ssh.key.login.allow in order to allow login via public key. This command mainly grants read access to ~/.ssh/authorized_keys for the ssh server.
    2. Create command user.ssh.key.authorize in order to import public keys into ~/.ssh/authorized_keys via command. Already present entries are not inserted.
    3. Remove Lombok plugin installation steps inside package.install.java.ide.via.eclipse because an update of Flatpak broke this.
  • 2021-08-29:
    1. #79: net.splitcells.website.server now renders text files with the file suffix .html instead of .txt. For the end user it means, that links to these file needs to be adjusted. This needs to be done, because static file webservers need to know the file type. Otherwise, text files transformed to HTML are not rendered correctly on web browsers. In practice this is used in order to serve the license files to splitcells.net. See this example.
  • 2021-08-29:
    1. Create method Paths.removeFileSuffix in order to unify file suffix manipulation implementations.
    2. #79: Render new license info on website.
    3. #s2: Create Host independent ticket numbering. Numbering is done via a prefix, that indicates the server hosting the ticket. This is documented in the changelog description located at the start.
  • 2021-08-28:
    1. Create helper command wait.interactively.until in order to wait until condition is fulfilled.
  • 2021-08-28:
    1. Fix licensing issues found via FOSSA.
  • 2021-08-24:
    1. Add secondary arguments to maven.execute command.
    2. Add ENFORCING_UNIT_CONSISTENCY environment property to Dem, so it can be set during program startup without programming.
    3. Create project command execute.example for gel.sheath in order to make easy to create custom execution command.
  • 2021-08-14:
    1. user.bin.configure now does not require additional user specific implementation. The command now works out of the box without an error message.
  • 2021-08-11:
    1. Server SVG images from source folder by webserver and add them to the layout.
    2. Deprecated untyped repositories in webserver.
    3. Render LaTex math formulas via MathJax in website.
    4. Translate local image links in CommonMark to the link of the website.
  • 2021-08-10:
    1. command.repositories.install now only installs sh, Bash and Python commands.
  • 2021-08-10:
    1. Create command project.repository.register in order to omit editing config files manually.
  • 2021-08-09: Create net.splitcells.network.deploy.build for deploying the build process on multiple computers.
  • 2021-08-08: command.repositories.install now strips known file suffixes during installation. This way os.state.interface repos can now state their file endings and thereby have better IDE support in such repos.
  • 2021-08-05:
    1. Rename net.splitcells.dem.utils.CommonFunctions#hash_code to hashCode.
  • 2021-08-05:
    1. Fix Dependabot alert.
    2. Make hashCode and equals of net.splitcells.gel.rating.framework.MetaRatingI consistent.
    3. Make hashCode of HasMinimalSize, HasSize, MinimalDistance, MinimalDistanceBasedOnDiffs, Compliance, Cost, BoolI, Comparators more consistent to equals, in order to improve Code quality score in lgtm.com.
  • 2021-07-08:
    1. Default configuration of Dem's process does not ensure determinism or randomness.
  • 2021-07-04:
    1. #61 Remove XSL parameter from rendering API in webserver.
  • 2021-07-03:
    1. Port 'repo.synchronize.with' to Python, add standardized argument handling and use better sub commands for each synchronization step. Also adds a logging message in case of error.
  • 2021-07-01:
    1. Remove experimental web layouts.
  • 2021-06-27:
    1. Publish Ses project.
    2. Limit depth of Local Path Context in default web layout.
    3. Render Local Path Context for CommonMark documents.
  • 2021-06-27 Log error stack traces in web server.
  • 2021-06-26 Add optimization to den.xsd.
  • 2021-06-25:
    1. #8 Remove deprecated constructor ProjectRenderer.
    2. #8 Provide path /net/splitcells/website/layout/build in server, in order to refresh project layout.
    3. #8 Clean up error logging in HttpServer.
    4. #8 Add description to RaterBasedOnLineValue based on classifier.
    5. Remove verification step after repair inside repo.repair in order to prevent duplicate verification calls.
    6. Install project commands in Ossi from repos listed in ~/.config/net.splitcells.os.state.interface/project.repositories. In other words: command.repositories.install and command.managed.install.project.commands now each have their own repo list. The reason for this is the fact, that repos for projects cannot be installed like repos for commands in OSSI. The reason for this, is the fact, that files located in the src folder of the project repo, may not work as an independent command.
    7. Use ~/.config/net.splitcells.os.state.interface/command.repositories for command.repositories.install. This way it is easier to understand the Ossi config files.
  • 2021-06-25:
    1. #8 Create index file, for standard analysis.
  • 2021-06-25 Determine project's source folder correctly in ProjectRenderer.
  • 2021-06-24:
    1. #8 Rename ForallI to ForAll, in order to simplify name.
    2. #8 Create valid XML for natural argumentation.
    3. Use established px default value for default font-size in default web layout.
    4. Rename ConstraintAI#process_lines_before_removal to processLinesBeforeRemoval in order to unify naming.
    5. Rename ConstraintAI#register_before_removal to registerBeforeRemoval in order to unify naming.

    7. Rename ConstraintAI#process_line_addition to processLineAddition in order to unify naming.
    8. Prevent random test error in SimplifiedAnnealingProblemTest#testProbability.
    9. Adjust default value of ProcessPath, so it does not clutter project repo, if the program is executed with default settings inside IDE.
  • 2021-06-23: #8 Remove deprecated usage of net.splitcells.gel.data.database.DatabaseI and mark these as protected. These constructors will be made private in the future.
  • 2021-06-21: Remove net.splitcells.gel.problem.Problem#toSolution(), because it is not used and was not implemented yet.
  • 2021-06-19: Create command convention repo.is.clean. Exits with 0, if this repo can be synchronized and else exits 1. This can be used as a safeguard for automated synchronization command by exiting a command, when uncommitted changes are present.
