The two basic scheduler classes you are likely to start with are SingleBranchScheduler and Periodic, but you can write a customized subclass to implement more complicated build scheduling. This is used in status displays, and is also available in the build property scheduler. This can also be an IRenderable object which will render to a list of builder names (or a list of IRenderable that will render to builder names). This can be used to access the data API. The owner property may be of particular interest, as its contents (as a list) will be added to the list of “interested users” ( Doing Things With Users ) for each triggered build. http://soenen-pneus.com/upload/cp-x5021n-manual.xml

For example For example, when a change to codebase A occurs, a scheduler must invent a sourcestamp for codebase B. Source steps that specify codebase B as their codebase will use the invented timestamp. This is the Simplest form, use it if no special overrides are needed. In this form, just the names of the codebases are listed. In this form, the per-codebase overrides of repository, branch and revision can be specified. The codebase definitions are combined in a dictionary keyed by the name of the codebase. Unimportant Changes are accumulated until the build is triggered by an important change. The default value of None means that all Changes are important. If a Change is allowed by the change filter, but is deemed unimportant, then it will not cause builds to start, but will be remembered and shown in status displays. The default value of None does not filter any changes at all. This defaults to False and only applies when fileIsImportant is given. By default it lists the type and name of the scheduler triggering the build. All these schedulers are defined in modules under buildbot.schedulers, and the docstrings there are the best source of documentation on the arguments taken by each one. Only one instance of the scheduler will be active. If that instance becomes inactive, due to its master being shut down or failing, then another instance will become active after a short delay. This provides resiliency in scheduler configurations, so that schedulers are not a single point of failure in a Buildbot infrastructure. The behavior is nondeterministic, based on the timing of polling by inactive schedulers. The failover is non-revertive. The filter can most generically be specified as a ChangeFilter. Set up a ChangeFilter like this: For example, if a commit is pushed toIn order to record aIf no filter object is given to a scheduler, then all changes will be built (subject to any other restrictions the scheduler enforces). http://www.liszt.art.pl/files-cfk/cp-x445-service-manual.xml

All these Schedulers are defined in modules under buildbot.schedulers, and the docstrings there are the best source of documentation on the arguments taken by each one. It follows exactly one branch, and starts a configurable tree-stable-timer after each change on that branch. When the timer expires, it starts a build on some set of Builders. This scheduler accepts a fileIsImportant function which can be used to ignore some Changes if they do not affect any important files. If treeStableTimer is set, then a build is triggered for each set of Changes which arrive within the configured time, and match the filters. If new changes are made during this interval, the timer will be restarted, so really the build will be started after a change and then after this many seconds of inactivity. SingleBranchScheduler ( The full builds do not run quite so quickly (they wait 5 minutes), so hopefully if the quick builds fail due to a missing file or really simple typo, the developer can discover and fix the problem before the full builds are started. Both schedulers only pay attention to the default branch: any changes on other branches are ignored. Each scheduler triggers a different set of Builders, referenced by name. If treeStableTimer is set, then a build is triggered for each set of Changes which arrive within the configured time, and match the filters. If new changes are made on the same branch during this interval, the timer will be restarted. An example might be a packaging step: you might only want to produce.deb or RPM packages from a tree that was known to compile successfully and pass all unit tests. Another example is if you want to skip the full builds after a failing quick build of the same source code. Or, if one Build creates a product (like a compiled library) that is used by some other Builder, you’d want to make sure the consuming Build is run after the producing one. http://fscl.ru/content/ecs-865g-m8-motherboard-manual

There is a special kind of scheduler named Dependent that will watch an upstream scheduler for builds to complete successfully (on all of its Builders). Each time that happens, the same source code (i.e. the same SourceStamp ) will be used to start a new set of builds, on a different set of Builders. This downstream scheduler doesn’t pay attention to Changes at all. It only pays attention to the upstream scheduler. Note that, for SourceStamps generated by a Dependent scheduler, the revision is None, meaning HEAD. If any changes are committed between the time the upstream scheduler begins its build and the time the dependent scheduler begins its build, then those changes will be included in the downstream build. See the Triggerable scheduler for a more flexible dependency mechanism that can avoid this problem. Note that this is an instance, not the name of the scheduler. When True, it uses the last seen revision for each codebase that does not have a change. When False (the default), codebases without changes will use the revision from the codebases argument. By default this setting is False. Note that this scheduler only lets you control the time between builds, not the absolute time-of-day of each Build, so this could easily wind up an evening or every afternoon scheduler depending upon when it was first activated. The configuration syntax is very similar to the well-known crontab format, in which you provide values for minute, hour, day, and month (some of which can be wildcards), and a build is triggered whenever the current time matches the given constraints. This can run a build every night, every morning, every weekend, alternate Thursdays, on your boss’s birthday, etc. The builds will be triggered whenever the current time matches these values. The full list of parameters is: When True, it uses the last seen revision for each codebase that does not have a change. http://iacfhouston.com/images/canon-pc1084-manual.pdf

When False (the default), codebases without changes will use the revision from the codebases argument. The default of this value is False. This defaults to 0, meaning an hourly build. See try for complete details. The former monitors a job directory, specified by the jobdir parameter, while the latter listens for PB connections on a specific port, and authenticates against userport. This lets the administrator control who may initiate these trial builds, which branches are eligible for trial builds, and which Builders should be used for them. All of them enforce more security than the usual buildmaster ports do. Any source code being built can be used to compromise the worker accounts, but in general that code must be checked out from the VC repository first, so only people with commit privileges can get control of the workers. The usual force-build control channels can waste worker time but do not allow arbitrary commands to be executed by people who don’t have those commit privileges. However, the source code patch that is provided with the trial build does not have to go through the VC system first, so it is important to make sure these builds cannot be abused by a non-committer to acquire as much control over the workers as a committer has. Ideally, only developers who have commit access to the VC repository would be able to start trial builds, but unfortunately the buildmaster does not, in general, have access to VC system’s user list. There are currently two ways to set this up: The buildmaster admin sets the ownership and permissions of this directory to only grant write access to the desired set of developers, all of whom must have accounts on the machine. The buildbot try command creates a special file containing the source stamp information and drops it in the jobdir, just like a standard maildir. When the buildmaster notices the new file, it unpacks the information inside and starts the builds.

If the buildmaster machine happens to also house the VC repository, then it can be fairly easy to keep the VC userlist in sync with the trial-build userlist. If they are on different machines, this will be much more of a hassle. It may also involve granting developer accounts on a machine that would not otherwise require them. The arguments must include the inlet directory and the revision information. The disadvantages are that it is less secure (while the cred authentication system does not expose the password in plaintext over the wire, it does not offer most of the other security properties that SSH does).Also remember that the buildmaster must be able to read and write to the jobdir as well. Be sure to watch the twistd.log file ( Logfiles ) as you start using the jobdir, to make sure the buildmaster is happy with it. If your submitted try jobs are rejected with BadJobfile, try increasing this limit with a snippet like this in your master.cfg: See twisted.application.strports for details. That step can optionally wait for the scheduler’s builds to complete. This provides two advantages over Dependent schedulers. First, the same scheduler can be triggered from multiple builds. Second, the ability to wait for Triggerable ’s builds to complete provides a form of “subroutine call”, where one or more builds can “call” a scheduler to perform some work for them, perhaps on other workers. The Triggerable scheduler supports multiple codebases. The scheduler filters out all codebases from Trigger steps that are not configured in the scheduler. Here is a fully-worked example: BuildFactory (). BuildFactory () This scheduler triggers builds at a particular time of day, week, or year, exactly as the Nightly scheduler. However, the source stamp set that is used is provided by the last Trigger step that targeted this scheduler. Note that waitForFinish is ignored by Trigger steps targeting this scheduler. www.dhcrowntech.com/image/files/20221021_162952.pdf

If you click on that button, a dialog will let you choose various parameters for requesting a new build. Force buttons are ordered by this property in the UI (so you can prefix by 01, 02 etc in order to control precisely the order). See builderNames scheduler argument. The default value is a string parameter with a default value “force build”. This string can contain the placeholders (owner)s and (reason)s, which represents the value typed into the reason field. The default value is a username parameter. These can be arbitrary parameters, where the parameter’s name is taken as the property name, or AnyPropertyParameter, which allows the web user to specify the property name. The default value is an empty list. This defaults to the name of scheduler. What you need in your config file is something like: Here is an example of code on how you can define which user has which right: Several classes of parameters are available, each describing a different kind of input from a force-build form. For properties, this will correspond to the name of the property that your parameter will set. The name is also used internally as the identifier for in the HTML form. This is what is displayed to the user. This is what is displayed to the user. Buildbot will ensure the field sent by the user is not too large. This is useful for when you have lots of parameters, and defaults depends on e.g. the branch. This is implemented generically, and all parameters can update others. Beware of infinite loops! ForceScheduler (. CodebaseParameter ( This can be used to group a set of parameters together, and define the layout of your form. You can recursively include NestedParameter into NestedParameter, to build very complex UI. They take the horizontal space that they need. This can be used to declare complex build forms which won’t fit into one screen. The children fields are usually other NestedParameters with vertical layout. {-Variable.fc_1_url-

If omitted, it is set to 1 unless there are more than 3 visible child fields in which case it is set to 2. It adds the following arguments: It adds the StringParameter arguments, this type allows: It will be presented as a checkbox. If authentication is active, it will use the authenticated user instead of displaying a text-entry box. If multiple is false, then its result is a string - one of the choices. If multiple is true, then the result is a list of strings from the choices. An example of this is provided by the source for the InheritBuildParameter class. Note that this only affects the validation of the form request; even if this argument is False, there is no HTML form component available to enter an arbitrary value. The default value is a string parameter. The default value is a string parameter. The default value is a string parameter. The default value is a string parameter. The user can either write some text to a text area, or select a file from the browser. Note that the file is then stored inside a property, so a maxsize of 10 megabytes has been set. You can still override that maxsize if you wish. The patch is stored within the sourcestamp, and associated to a codebase. That is why PatchParameter must be set inside a CodebaseParameter. PatchParameter ( The user is presented with a list of compatible builds from which to choose, and all forced-build parameters from the selected build are copied into the new build. The new parameter is: This function is given the master Status instance as first argument, and the current builder name as second argument, or None when forcing all builds. The choice is assigned to the workername property for the build. The enforceChosenWorker functor must be assigned to the canStartBuild parameter for the Builder. Stricter parameter name and type should be preferred. Typically, at first sight it looks like a bunch of complicated concepts that make no sense and whose relationships with each other are unclear.

After some time and some reread, it all slowly starts to be more and more meaningful, until you finally say “oh!” and things start to make sense. Once you get there, you realize that the documentation is great, but only if you already know what it’s about. Here I’m going to (try to) explain things in a way that would have helped me more as a newcomer. The approach I’m taking is more or less the reverse of that used by the documentation, that is, I’m going to start from the components that do the actual work (the builders) and go up the chain from there up to change sources. I hope purists will forgive this unorthodoxy. Here I’m trying to clarify the concepts only, and will not go into the details of each object or property; the documentation explains those quite well. This document will refer to Buildbot 0.8.5 which was current at the time of writing, but hopefully the concepts are not too different in other versions. All the code shown is of course python code, and has to be included in the master.cfg master configuration file. The other fundamental piece of information that a builder needs is, of course, the list of things it has to do (which will normally run on the chosen worker). In Buildbot, this list of things is represented as a BuildFactory object, which is essentially a sequence of steps, each one defining a certain operation or command. For this example, we are going to assume that our super software project can be built using a simple make all, and there is another target make packages that creates rpm, deb and tgz packages of the binaries. In the real world things are usually more complex (for example there may be a configure step, or multiple targets), but the concepts are the same; it will just be a matter of adding more steps to a builder, or creating multiple builders, although sometimes the resulting builders can be quite complex. dienlanhhaiphong247.com/upload/files/Dp8020E-Manual.pdf

A step can be a shell command object, or a dedicated object that checks out the source code (there are various types for different repositories, see the docs for more info), or yet something else: This needs passwordless ssh. ShellCommand (. BuildFactory (). In this case, we only have one builder If our repository has other branches besides trunk, we could create another one or more builders to build them; in the example, only the checkout step would be different, in that it would need to check out the specific branch. Depending on how exactly those branches have to be built, the shell commands may be recycled, or new ones would have to be created if they are different in the branch. You get the idea.Or we could have a builder that performs a more thorough test by also doing make test or other targets. You get the idea.This is the job of the scheduler, which is a fancy name for an element that waits for some event to happen, and when it does, based on that information decides whether and when to run a builder (and which one or ones). There can be more than one scheduler. I’m being purposely vague here because the possibilities are almost endless and highly dependent on the actual setup, build purposes, source repository layout and other elements. In our example, that’s how we would trigger a build every hour: Every hour this hourly scheduler will run the simplebuild builder. If we have more than one builder that we want to run every hour, we can just add them to the builderNames list when defining the scheduler and they will all be run.The typical dynamic scheduler is one that learns about changes in a source repository (generally because some developer checks in some change), and triggers one or more builders in response to those changes. Let’s assume for now that the scheduler “magically” learns about changes in the repository (more about this later); here’s how we would define it: When such changes are detected, and the tree has been quiet for 5 minutes (300 seconds), it runs the simplebuild builder. The treeStableTimer helps in those situations where commits tend to happen in bursts, which would otherwise result in multiple build requests queuing up. First we create two builders, one for each branch (see the builders paragraph above), then we create two dynamic schedulers: SingleBranchScheduler ( Another feature of the scheduler is that it can be told which changes, within those it’s paying attention to, are important and which are not. For example, there may be a documentation directory in the branch the scheduler is watching, but changes under that directory should not trigger a build of the binary. This finer filtering is implemented by means of the fileIsImportant argument to the scheduler (full details in the docs and - alas - in the sources). Note that periodic schedulers don’t need a change source, since they only depend on elapsed time; dynamic schedulers, on the other hand, do need a change source. This determines the extent of the information that is passed down to the schedulers. While these two methods are probably the most common, they are not the only possibilities; it is possible for example to have a change source detect changes by parsing some email sent to a mailing list when a commit happens, and yet other methods exist. The manual again has the details. We could have said: SingleBranchScheduler ( SingleBranchScheduler ( There are many reporters: a mail notifier, an IRC notifier, and others. They are described fairly well in the manual. For more details, look into the Reporters section of the Buildbot manual. So there’s much, much more to say about Buildbot. However, hopefully this is a preparation step before reading the official manual. Had I found an explanation as the one above when I was approaching Buildbot, I’d have had to read the manual just once, rather than multiple times. Hope this can help someone else.

Sign up for a free GitHub account to open an issue and contact its maintainers and the community.Using a forced builder would also mean that the nightly scheduler would trigger the same build again at its next schedule, which is not desirable. The force could also trigger that implementation builder. You can either add the parameters from the nightly into the form for the force scheduler, or else set those params up elsewhere so that either the force or the nightly will trigger a step that sets up the same parameters consistently. The result is that the state after such a manual trigger will be such that if no new commits have arrived when the scheduler triggers the next time, it will be the same result as if there were no new commits since the last normal trigger: No action taken.
