  141. 2023-12-17 Test repo commands
  142. 2023-11-27 (link): #252: Rename logging facilities as such. This avoids, that someone interprets such logging facilities as something else based on their complex names. The idea of a Domsole is not abandoned and therefore such an interface was recreated with an appropriate note.
    1. CommonMarkDui -> CommonMarkLog.
    2. Domsole -> Logs
    3. Pdsui -> LogImpl
    4. Ui -> Log
    5. UiRouter -> LogRouter
  143. 2023-11-19 (link): #213 repo.process now loads the list of sub repositories via ./.net.splitcells.os.state.interface.repo/sub-repo-names and not ./.net.splitcells.os.state.interface.repo/subs.json in order to simplify the format. ./.net.splitcells.os.state.interface.repo/sub-repo-names is now a command that is executed and returns a list of sub repo names, that are separated via new line symbols, which in turn is a csv file. This makes it also easier to make it compatible with other software like hakoerber's GRM.
  144. 2023-11-17 Define documentation inside program code
  145. 2023-11-15 Configure logging via external config and not code.
  146. 2023-10-25 (link): #242 net.splitcells.dem.data.set.map.Map#put now throws an exception, if the key is already present. This is done, because in this case, there is an increased chance, of a programming bug being present. If the value of the map should be updated regardless of the presence of the given key, the method ensurePresence should be used instead.
  147. 2023-10-07 (link): #254: Commit runtime data via JGit instead of git via a shell. This makes using git inside worker easier. It is also a preparation for making the network a portable program, that also could be used for bootstrapping deployments. See #259 for more details.
  148. 2023-10-05 Project Start: Provide scheduling tool for schools in general.
  149. 2023-10-02 Provide scheduling tool for schools in general.

  151. 2023-09-15 (link): #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.
  152. 2023-09-15 (link): #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.
  153. 2023-09-15 (link): Migrate articles of net.splitcells.network.blog to net.splitcells.network.community and delete the project net.splitcells.network.blog, because the blog provides insight into
  154. 2023-08-17 (link): #249 Provide default value for net.splitcells.website.server.Config#detailedXslMenu.
  155. 2023-08-14 (link): #249: Split net.splitcells.network root project into a root project, that is used for building all network projects, and a network file project containing documentation. This way the root folder of the network project is just a multi module Maven project for building and the projects sub folder contains all projects of the network project.
  156. 2023-07-13 (link): #249 Migrate Java's Path API usage to new FileSystem API, in order to support operation system unspecific deployment.
  157. 2023-07-12 Make the project deployable as a single jar.
  158. 2023-07-12 Project Start: Make the project deployable as a single jar.
  159. 2023-07-12 (link): #249 Provide file system API in order to not to rely on Paths specific to the operation system.
  160. 2023-07-12 (link): #249 Implement FileSystemViaClassResources in order to provide FileSystem API for class resources. This can be used in order to provide file systems via jar files.
  161. 2023-06-27 (link): #170 Line#values() are now read only, in order to allow more performant code, by not requiring lines to provide a new copy of line values for every Line#values() call.
  162. 2023-06-27 (link): :
    1. Rename ListI#list() into ListI#_list(), in order to simplify autocompletion for import statements in IDEs by avoiding name duplication with Lists#list().
    2. Migrate net.splitcells.dem.utils.ComonFunctions#removeAny to net.splitcells.dem.data.set.Set.removeAny().
  163. 2023-06-21 (link): #170 Table#columnsView now only returns a read-only access to the columns, in order to enable faster alternative Database implementations, that do not have writeable columns. Also, writeable access to the columns via the public interface was never planned. Especially, in the Table interface, that is thought to be a read-only interface.
  164. 2023-06-16 (link): #245 Notify users of echo.error call by default.
  165. 2023-06-15 (link): #170
    1. Rename net.splitcells.gel.data.allocation.Allocation* to net.splitcells.gel.data.assignment.Assignment*, which is more in line with the name of the core model problem the assignment problem.
    2. Provide new Allocations interface, that is the foundation of the Assignments interface. The key difference is, that the Allocations only allows one assignment for each demand and for each supply. This interface can be used instead, in order to improve the performance, if an appropriate usage is possible.
  166. 2023-06-14 (link): ##170: Add DatabaseI#addWithSameHeaderPrefix as a faster alternative to DatabaseI#add, if the line's header to be added to the database is a prefix to the database's header.

    2. Delete obsolete classes net.splitcells.dem.resource.communication.interaction.Dsui & DsuiTest, because it was not used.
    3. Delete obsolete interface net.splitcells.dem.resource.communication.interaction.Sui, because it has no function anymore as the previous classes were removed.
    4. Move content of net.splitcells.dem.resource.communication.interaction to net.splitcells.dem.resource.communication.log, in order to simplify package structure.

    2. Rename net.splitcells.dem.merger to net.splitcells.dem.api.
    3. Rename net.splitcells.gel.sheath to net.splitcells.gel.ext.
  175. 2023-04-13 (link): ##170: Extend Query with optional value containing the Allocations the Query is being applied to. This allows one to create constraints, that depend on the supply and demand Tables of assignments of the given problem.
  176. 2023-04-12 Clean up test tags
  177. 2023-04-12 Create table based on ints and floats
  178. 2023-04-12 (link): #170 Rename Table#line(int) to Table#orderedLine(int) in order to avoid misunderstandings by avoiding ambiguity.

  181. 2023-03-30 (link): #170 Require raters to implement toSimpleDescription in order always have a working report, for a given optimization problem.
  182. 2023-03-26 (link): #s109 repo.process should not create the folder of missing sub repos by default. If --command-for-missing is not set or is set as exit 1, the folder
  183. 2023-03-25 (link): Set#remove(Object) will throw an exception, if the given Object is not present inside the set. In this case there is a higher probability, that the developer made a programming mistake, compared to the case, where the to be removed element is really present. If the developer really intended optionally remove an element of a Set, the method Set#ensureRemoved(T) is provided instead.
  184. 2023-03-17 (link): ##170: Introduce HistoryForDatabase for debugging purposes. An instance can be connected to a given database via the DatabaseFactory, which can be viewed via the webserver in order to understand how the content of the given database was created.
  185. 2023-03-17 (link): Revers priorities of LogLevel so that LogLevel.DEBUG.smallerThan(LogLevel.ERROR) returns true.

  193. 2023-02-12 (link): #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.

    1. \#196 Create sane default config and behaviour regarding temporary data for, i.e. logging:
      1. Store logs etc. at ~./.local/state/net.splitcells.dem/src/main/[file type]/[program name]/[date time of program start]/ by default.
      2. Introduce the option RenderUserStateRepo, in order to render ~./.local/state/net.splitcells.dem, if desired. Thereby, the logs can be found at the website's file layout (/net/splitcells/website/layout.html).
      3. The server now has the internal file /net/splitcells/website/server/config/menu/detailed.xsl, that can be configured. This XSL script generates the website's menu. The result is used for the website's side menu, that is visible on most pages. A dedicated menu page, is also generated by the XSL script and available at /net/splitcells/website/main-menu.html. It has basically the same content as the side menu. While the side menu is not visible on mobile phones in the default layout, the dedicated menu page can be viewed on mobile phones as well. Mobile users have an easy access to this page, via a link at the very top of every page.

This is the basis required, so that constraints can be viewed via the web server. The end goal is to provide for each constraint a path, that starts with the problem's path and after that continues with the constraint node's path. For example: /net/splitcells/run/conway-s-game-of-life/forAll/timeSteps points to the constraint node of an instance of conway's game of life, that groups all values according to their time value. In other words, the aim is to provide a unique id for all constraint nodes, that can be easily discovered.
  210. 2022-11-19 (link): : \#s115 Speed up website deployment.: Introduce net.splitcells.website.server.Config.mutableProjectsPath in order to state, if projectsPath can be assumed to stay the same during the web servers execution. This speeds up the rendering of static websites enormously, because ProjectsRendererI caches projectsPath, if mutableProjectsPath is set to true.

RenderUserStateRepo is set to false by default, because this should only be rendered, if the user explicitly wants it, in order to prevent leakage of private information be accident. This could otherwise happen, if the user renders a website with defaults settings and uploads it without checking the results in detail.

    1. repo.process now uses bin/net.splitcells.osi.repos.peers in order to find all peer repos, that are on the same folder level as the current repo. Sub repos are repos located in the folder of the current repo. Peer repos are repos located at the same folder as the current repo. This make synchronizing local repos with online repo hosters like SourceHut and GitHub a lot easier, because before that, each repo had to be pushed manually, or via a script. This was more burdensome compared to pushing a meta to another meta repo, because online repo hosters typically do not allow nested hierachies of repos. Now one can push all SourceHut repos via repo.push.at.all, instead of using many instances of cd [...]; git remote show SourceHut || git remote add SourceHut [...]; git remote set-url SourceHut [...]; git push SourceHut.
    2. Introduction of the project file bin/net.splitcells.osi.repos.hosts. This command echos all hosts of the current repo, its subs and peers. This is used by repo.push.at.all in order to not only push all repos, but to also push these to all hosts (i.e. GitLab, GitHub, SourceHut etc.).
    3. Overall, the changes made it a lot easier to adapt to changes of the repo structure and its hosts. This is particularly the case, when mainstream git hosters are used. It makes it a lot easier, to create completely new commands.

  283. 2022-03-20 (link): :
    • The webserver now maps some paths to the root index file. This allows the user to interact with the live server more easily, as it does not have to write the root index file into the URL in order to open it. Thereby, the user does not have to handle an error, because it tried to open a website with the most common URL. In other words https://localhost:8443/index.html becomes https://localhost:8443.
  284. 2022-03-12 (link): echo.error now also sends the message to notify.error, if $echo_error_notifies_user is set to true. Thereby, it is more easily to know, if some optional feature was not executed during a long command. For instance, when a command synchronizes a repo with multiple other computers, a notification for each not available computer is helpful. In this case it can be normal, that some computers were not available during each synchronization, and therefore the execution as a whole does not have to be aborted or marked as a failure.

  289. 2022-02-25 (link): #158 Do not change the PATH during the installation of OS state interface: command.repositories.install.sh now does not call command.managed.environment.configure.sh and therefore does not edit ~/.bashrc. This avoids unexpected changes to the user configs. The command command.repositories.setup.sh was created, which is the original version of command.repositories.install.sh. This way there is still a command, that installs the OSSI project with full functionality.
  290. 2022-02-25 (link):
    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.
  291. 2022-02-23 (link):
    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.

    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.
  294. 2022-02-21 (link): #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.

  297. 2022-02-17 (link): : #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

  298. 2022-02-15 Generic Allocator's Fourth Version
  299. 2022-02-15 (link): : Comment On Generic Allocators Fourth Version (Gemini Link)
  300. 2022-02-14 (link): : #138 Create developer introduction.
  301. 2022-02-14 (link): : #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.
  302. 2022-02-12 (link): :
    1. #s68: Recommend stating the license in CommonMark files.
    2. #s68: Create repo for media files: This repo is named net.splitcells.network.media and is a peer repo to this repo cluster.
  303. 2022-02-12 (link): : #s66 Move suitable Dem guidelines to the network project.
  304. 2022-02-11 (link): :
    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.
  305. 2022-02-10 (link): : JPG images served by website server's resource extension now get the correct content type.
  306. 2022-02-07 (link): : SVG images served by website server's resource extension now get the correct content type.
  307. 2022-02-07 (link): : #43: Ensure at least 30% test coverage.
  308. 2022-02-05 (link): :
    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.
  309. 2022-02-04 (link): : #s68: Add peer repository net.splitcells.network.media to website.
  310. 2022-01-31 (link): : Make test coverage via codecov.io public. It can be seen on the README.
  311. 2022-01-30 (link): : 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.
  312. 2022-01-30 (link): : 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.
  313. 2022-01-23 (link): : #s27: Fix local path content for rendering of text files.
  314. 2022-01-23 (link): : #138: LinearDeinitializer now correctly selects the allocation of a supply.
  315. 2022-01-23 (link): : #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.
  316. 2022-01-23 (link): : Create command flatpak.gui, in order to easily find Flatpak's default GUI based application manager.
  317. 2022-01-21 Create minimal build with zero dependency except for the standard runtime
  318. 2022-01-21 (link): : Create command sh.scroll.enable.
    • Sometimes scrolling is not enabled in a shell. This can be the case, if one is opened over ssh. This command enables scrolling for the current session. This command is not used for scripting, but makes it easy to look this command up for manual usage.
  319. 2022-01-18 (link): : Create command ssh.execute in order to execute commands on remote server in foreground.
  320. 2022-01-16 (link): : Create and publish blog article A Case For Repo Process.
  321. 2022-01-11 (link): : #s58 Implement first draft for injecting blogs of different projects into the network blog.
  322. 2022-01-09 (link): : #148: Fix local path context for rendered XML files in website server.
  323. 2022-01-09 (link): : 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.
  324. 2022-01-09 (link): : #138: Make default values of StaticFlags more reasonable performant.
  325. 2022-01-05 (link): : #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.
  326. 2022-01-02 (link): : #138 Fix user command rendering via UserCommandRenderer by rendering command tree with http://splitcells.net/den.xsd namespace.
  327. 2021-12-31 (link): : #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.
  328. 2021-12-28 (link): : #s44 The Domsole now filters log messages with a lesser priority than INFO by default. This behaviour can be overwritten with the Option MessageFilter.
  329. 2021-12-27 (link): :
    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.
  330. 2021-12-27 (link): : #s44 Create first draft of HTML link Validator based on heuristics regarding HTML parsing, so that a framework does not need to be included.
  331. 2021-12-26 (link): : #s44 Rename Validator to SourceValidator in order to clarify purpose, because a validator for rendered files via the web server is needed.
  332. 2021-12-23 (link): : 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.
  333. 2021-12-23 (link): : #138 CSV rendering via chart.js now renders the requested csv file. Previously, this renderer always rendered the same file, regardless of the request
  334. 2021-12-20 (link): :
    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).
  335. 2021-12-19 (link): : 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.
  336. 2021-12-19 (link): : #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.
  337. 2021-12-16 (link): : 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.
  338. 2021-12-13 (link): : #132 Justify current bias toward online optimization.
  339. 2021-12-12 (link): : 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.
  340. 2021-12-11 (link): : #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.
  341. 2021-12-10 (link): : #138 Remove temporary duplicate assignments during HistoryI reset, in order to improve performance.
  342. 2021-12-09 (link): :
    1. #148 Unify method naming by renaming 2 methods:
      1. Rename Contraint#register_addition to Contraint#registerAddition.
      2. Rename Contraint#register_before_removal to Contraint#registerBeforeRemoval.
    2. #148 Fix typos:
      1. Rename Database#subscriberToBeforeRemoval to Database#subscribeToBeforeRemoval.
      2. Rename Database#subscriberToAfterRemoval to Database#subscribeToAfterRemoval.
  343. 2021-12-05 (link): : Ordered#compare_to now does not always double-check equality.
  344. 2021-12-05 (link): : Fix implementation and runtime check of HistoryI#resetTo.
  345. 2021-12-05 (link): : #148 Fix local path context for XML files: Add path information to XML documents during website rendering.
  346. 2021-12-05 (link): : #148 Fix local path context for XML files: Remove choice Documents from custom XML format. A choice elements can be wrapped with an article element in order to get the same result, but with metadata support.
  347. 2021-12-04 (link): :
    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.
  348. 2021-12-03 (link): : 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.
  349. 2021-11-29 (link): :
    1. #138 Create test.capabilities and test.integration in order to execute tests, that require relatively long time for execution.
  350. 2021-11-27 Supporting Arbitrary Website Renderers
  351. 2021-11-27 (link): :
    1. #s22 Fix the ordering of MetaRatingI. Previously, the order was inverse: a meta rating with cost of 0 was worse than a meta rating with cost of 1.
    2. shell.width.sh now works in Bourne shell as well.
  352. 2021-11-27 (link): :
    1. #s22 Implement backtracking optimization:
      1. Implements backtracking as an OnlineOptimization.
      2. In this context EnumerableOptimizationSpace was created in order to provide a search space for backtracking.
    2. #142 Create net.splitcells.website.html.content project in order to provide an alternative HTML styling.
    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.
  353. 2021-11-27 (link): : #s22: Rename Optimization interface to OfflineOptimization in order to clarify the difference to the new OnlineOptimization interface.
  354. 2021-11-21 (link): : #s22: Rename net.splitcells.gel.solution.optimization.Optimization to OfflineOptimization in order to clarify its meaning.
  355. 2021-11-20 (link): : Fix text file rendering in web server via txt file suffix.
  356. 2021-11-20 (link): : #37 Simplify default web layout.
  357. 2021-11-08 (link): :
    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.
  358. 2021-11-06 (link): :
    1. #10 Rename net.splitcells.dem.data.order.Comparison.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 comparison in order to unify naming.
  359. 2021-11-05 (link): : 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.
  360. 2021-10-31 (link): :
    1. #55 Minimize number of used languages and protocols: Create guidelines for the formats used in the source code.
    2. #117 Document N-Queen-Problem for users: The file is located here.
  361. 2021-10-31 (link): : #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.
  362. 2021-10-25 (link): #90 Fix deployment of CommonMark files: Before the patch CommonMark were not rendered and uploaded via the website server.
  363. 2021-10-22 Test whether repo commands can detect bit rot in git repos.
  364. 2021-10-22 (link): 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.
  365. 2021-10-20 Support different backends for Gel's API
  366. 2021-10-19 (link): #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.
  367. 2021-10-18 (link): : #100 Fix links from CommonMark files transformed to CommonMark files: Before the patches the webserver could not create links between CommonMark files, because the file suffix .md was not replaced with .html. .md are the file suffix for the source CommonMark files. .html are the file suffix for the rendered CommonMark files.
  368. 2021-10-18 (link): :
    1. #10 Privatize Constructor of NotImplementedYet exception. Thereby, the public API is unified.
    2. #10 Privatize Constructor of LinkTranslator for CommonMark. Thereby, the public API is unified.

  373. 2021-10-03 (link): #101 Support gemini protocol for network blog: The site was deployed to splitcells-net.srht.site(Gemini link).
  374. 2021-10-02 (link): #99 Add license headers to all webservers default content:
    1. The network's blog articles
    2. CSS files
    3. Javascript files
    4. HTML files
    5. Layout/XSL files
  375. 2021-10-01 (link): : Install man pages to ~/bin/man/man1 so that the common man command can find and display man pages installed by os state interface.
  376. 2021-09-30 (link): #s6 Jumpstart State Network Optimization (SEP): Provide an API in order to manage and work on complex optimizations, that consist of multiple sub problems. Thereby the SchoolSchedulingTest was migrated to new the API in order to simplify future code for this test.
  377. 2021-09-28 Release software to Maven Central repositories
  378. 2021-09-28 Create machine learning interface
  379. 2021-09-19 (link): Define chrome installation command via flatpak.
  380. 2021-09-18 (link): : Remove command system.configure.auto of OS state interface project.

  382. 2021-09-17 (link): : #10 Introduce the first pure project: net.splitcells.dem.merger
  383. 2021-09-17 (link): : #10
    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.
  384. 2021-09-15 (link): : #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.
  385. 2021-09-14 (link):
    1. Create concept presentation for Gel based on thought experiment.
    2. Support serving raw HTML files via webserver.
    3. Render changelog on website.
  386. 2021-09-12 Support usage of website in text form
  387. 2021-09-11 (link): : 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.
  388. 2021-09-11 (link): : 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.
  389. 2021-09-05 (link): :
    1. Disable caching for default weblayout in order to keep CSS styling in webbrowser up to date.
  390. 2021-09-04 (link): :
    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.
  391. 2021-08-29 (link): :
    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.
  392. 2021-08-29 (link): :
    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.
  393. 2021-08-28 (link): :
    1. Fix licensing issues found via FOSSA.
  394. 2021-08-28 (link): :

  413. 2021-07-04 (link): :
    1. #61 Remove XSL parameter from rendering API in webserver.
  414. 2021-07-03 (link): :
    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.
  415. 2021-07-01 (link): :
    1. Remove experimental web layouts.
  416. 2021-06-27 (link): Log error stack traces in web server.
  417. 2021-06-27 (link): :
    1. Publish Ses project.
    2. Limit depth of Local Path Context in default web layout.
    3. Render Local Path Context for CommonMark documents.
  418. 2021-06-26 (link): Add optimization to den.xsd.
  419. 2021-06-25 (link): Determine project's source folder correctly in ProjectRenderer.
  420. 2021-06-25 (link): :
    1. #8 Create index file, for standard analysis.
  421. 2021-06-25 (link): :
    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.
  422. 2021-06-24 (link): :
    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.
    6. Rename ConstraintAI#register_additions to registerAdditions 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.
  423. 2021-06-23 (link): : #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.
  424. 2021-06-21 (link): : Remove net.splitcells.gel.problem.Problem#toSolution(), because it is not used and was not implemented yet.
  425. 2021-06-19 (link): : 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.
  426. 2021-06-06 (link): : #54: Integrate CommonMark documentation into project rendering.
  427. 2021-04-13 (link): : #7: Model and solve oral exam problem.
  428. 2021-04-12 (link): : #46: Use deterministic environment and execution in CI.
  429. 2021-04-07 (link): : #42: Make Gel workspace visible in website.
