Dec 13, 2010 · Actually adding a commit hook in Mercurial is pretty simple. You just add a line to your .hgrc file: [hooks] commit = powershell \path\to\hg-commit-hook.ps1 It seems that Mercurial preserves the environment for hooks, so you don't seem to have to worry about absolute paths and such like you do in Subversion.
all hooks will take ui, repo,hooktype -- that's a very common pattern in Mercurial code (core, extensions, hooks, whatever) I don't care what other arguments Mercurial passes to my hook, so I just declare **kwargs so it can pass anything it likes . use repo[None] to get a changectx object representing the working dir, i.e. what is about to be committed
May 23, 2016 · So I'll use pretxnchangegroup and return non 0 non false value as Mercurial documentation states. A hook that executes successfully must exit with a status of zero if external, or return boolean “false” if in-process. Failure is indicated with a non-zero exit status from an external hook, or an in-process hook returning boolean “true”.
3 1. To define hooks, Mercurial uses paths given in the config file `.hg/hgrc`. To enable Mercurial to call `ikiwiki-wrapper` automatically after blog/wiki setup, ikiwiki thus needs to create `hgrc`.
May 05, 2016 · To use one of the hooks provided by this package edit your hgrc file of your Mercurial repository and add these lines: [hooks] pretxncommit.pep8 = python:hghooks.code.pep8hook pretxncommit.pyflakes = python:hghooks.code.pyflakeshook pretxncommit.pdb = python:hghooks.code.pdbhook pretxncommit.jslint = python:hghooks.code.jslinthook.
In Mercurial, hooks are not revision controlled, and do not propagate when you clone, or pull from, a repository. The reason for this is simple: a hook is a completely arbitrary piece of executable code. It runs under your user identity, with your privilege level, on your machine.
Writing your own hooks. The acl extension lets you control which remote users are allowed to push changesets to a networked server. Here is a brief list of the hooks that Mercurial supports. If the working directory is being merged, it will not change this parent. Right now there are two entry points:. If this hook fails, the changesets will not be transmitted. The ID of the newly added changeset. This way you will enforce the correctness of every commit. Here is a general framework for that type of hook. As a final aside, note in the example above the use of sed 's in-place editing feature to get rid of trailing whitespace from a file. To use add the following to your project. Improve this question. There are two configuration options for that:. Hooks can be overridden. Nov 16, If the hook succeeds, creation of the tag proceeds. There are some caveats to running TortoiseHG on windows, particularly with ssh. It all changesets will be grouped in one comment and will be added in every ticket mentioned in the changeset message. This will scan all the jobs that's configured to check out the specified URL, and if they are also configured with polling, it'll immediately trigger the polling and if that finds a change worth a build, a build will be triggered in turn. In some cases, you may be exposed to hooks that you did not install yourself. You can use either the precommit or pretxncommit hook to tell whether you have a trailing whitespace problem. Note that it allows the first commit the one after hg branch. It is run before Mercurial has any of the metadata for the commit, such as the files to be committed, the commit message, or the commit date. The database must be configured to allow this user to connect from whatever host you are running the bugzilla hook on. If a remote client pulled changes from this repository, source will be serve. If a parameter is named url , it will contain the URL of a remote repository, if that can be determined. The Overflow Blog. Use the server time in the trachooks. Original question here. The repo parameter is a localrepository object. Find centralized, trusted content and collaborate around the technologies you use most. Python version None. These hooks are defined as python in-process hooks to get portability between Windows and Linux, as well as to get nice error messages because in-process hooks can use the ui. This controlling hook is run before Mercurial begins to add a group of changesets from another repository. An interesting use of a commit-related hook is to help you to write cleaner code. Since fixing a bunch of commit messages at push time is a big headache requiring mq, we'll also define a pretxncommit hook that well-behaved developers can use to enforce rules at commit time. However the hook does not trigger, and I can push to my repo without a problem. This makes it possible to let your users maintain their own usermap entries. As you can see in the above example, by putting the changeset between brackets we automatically generate a Trac link to that changeset in the ticket comment. Hook parameters are passed to the hook as environment variables. You can install this hook on a shared server, so that any time a remote user pushes changes to this server, the hook gets run. Project links Homepage. Likewise, while being able to commit on a plane is pointless, there's definite value in not needing to have a connection to the server to do core version control operations. Boolean-valued parameters are represented as Python bool objects. You can write a hook either as a normal program—typically a shell script—or as a Python function that is executed within the Mercurial process. If the client that obtained changes from this repository was local, source will be bundle , pull , or push , depending on the operation the client performed.

Hook Examples Getting started writing hooks can be tricky, especially in-process Python hooks. On the one hand, writing hooks is a good way to learn your way around Mercurial's internals. But if you don't already know those internals, getting your hooks working is hard work. Hence this page, which contains documented hook code based on real-world hooks. I'm going to assume that you have a working knowledge of Python here. You don't need to be an expert, but please work through a tutorial or two before trying to write Mercurial hooks. Note that MercurialApi is the best available documentation for the internal APIs that you will most commonly use writing hooks. If anything in here seems unclear, pop over to MercurialApi to see if there is a better explanation there. Abort on fatal error hooks use the peculiar convention of returning a true value to indicate failure. This is weird, but 1 it's consistent with external hooks, which return non-zero to indicate failure the usual convention for child processes on Unix and 2 it means that falling off the end of a hook implicitly returning None is success Precommit: disallow bad branch Say you have local policy that states branches must be named like major. You don't want developers creating new branches willy-nilly, because that can cause a mess. Imagine what would happen if someone accidentally merged 1. Bad idea. So let's take advantage of our branch name convention to figure out which branch is later, and only allow merges from earlier to later branches. Raise ValueError if branch is not a valid branch name according to local policy. Now, one big hook to enforce both bits of policy. This also disallows another strange type of merge that I discovered while writing the hook. Whether you want to disallow it is your business, of course. If that's not the case, we'll blow up with a ValueError here. If you're trying to enforce new policy on a repo with existing branch names, this will have to be more flexible. So disallow it. Since we can't enforce hooks for all distributed clones because hooks don't transfer, we have to enforce it on a known-good central repository. Thus, we have to write a pretxnchangegroup hook. Since fixing a bunch of commit messages at push time is a big headache requiring mq, we'll also define a pretxncommit hook that well-behaved developers can use to enforce rules at commit time. These hooks are defined as python in-process hooks to get portability between Windows and Linux, as well as to get nice error messages because in-process hooks can use the ui. You must define checkMessage to define the rule and printUsage to explain the rule to the user. Given some work, the two methods could be combined into a more generic method, but that is an exercise left to the developer. To use add the following to your project. Here is a general framework for that type of hook. In python! So you cannot 'hg cat' them all. If you need to check file contents, write a native python hook. Note that it allows the first commit the one after hg branch. This might be abused. A possible improvement would be to only allow this single commit if the stable branch does not exists yet. Instead, it may expose incoming changesets as patches mailing them or showing in a web interface. This could be used to ease contributing changes to a project.
Each item in the usermap section contains an email address on the left, and a Bugzilla user name on the right. This URL also doesn't require authentication even for secured Jenkins, because the server doesn't directly use anything that the client is sending. If this section is not present, all users that are not explicitly denied are allowed. It runs polling to verify that there is a change, before it actually starts a build. Information for writers of hooks. This will allow you to check for problems only the exact files that are being committed. Feb 1, If it exits with a non-zero status, it is considered to have failed. This indirection through a wrapper script is necessary, because processmail expects to be run with its current directory set to wherever you installed Bugzilla; you can't specify that kind of constraint in a sudoers file. It adds a comment to the bug that looks like this you can configure the contents of the comment—see below :. You don't need to be an expert, but please work through a tutorial or two before trying to write Mercurial hooks. Only set if the working directory is being merged. I plan to change the actual hook implementation in the future, push will be allowed, but first I need to get any hook functional with Kallithea. Please try enabling it if you encounter problems. Since we can't enforce hooks for all distributed clones because hooks don't transfer, we have to enforce it on a known-good central repository. By default, this is set to An external hook is passed to the shell of the user running Mercurial. Mercurial defines a number of events that occur before an activity starts; or after it starts, but before it finishes. This hook is short, but not very helpful. When you run a Mercurial command in a repository, and the command causes a hook to run, that hook runs on your system, under your user account, with your privilege level. Copyright , , , Bryan O'Sullivan. A possible improvement would be to only allow this single commit if the stable branch does not exists yet. While this hook is running, if other Mercurial processes access this repository, they will be able to see the almost-added changesets as if they are permanent. Thanks to Gabriel Rodriguez pep support. Choosing how your hook should run. Customizing the output of Mercurial. You can also use the tortoiseplink. The source of these changes. This is run before creating a tag. With DVCS , there's no central server, but that just means that your central server is determined by convention, not by the software, and it's much easier to set up "slave" repositories for remote sites. One use for this hook is to disable the ability to commit new changesets, while still allowing incoming changesets. In multi-user situations, you should not rely on environment variables being set to the values you have in your environment when testing the hook. This will scan all the jobs that's configured to check out the specified URL, and if they are also configured with polling, it'll immediately trigger the polling and if that finds a change worth a build, a build will be triggered in turn. By default, the notify hook includes a diff of every changeset that it sends out; you can limit the size of the diff, or turn this feature off entirely. This controlling hook is run before Mercurial begins to add a group of changesets from another repository. Improve this answer. Where changes are going—remote repository URLs. Actually adding a commit hook in Mercurial is pretty simple. As for the message generation, Mercurial's log command allows you to specify a template for its output, including substitution variables and some simple formatting functions. If the client is using SSL, this will be of the form remote:https According to Eric, it's fairly user-friendly, especially for Subversion users, and it's fairly Windows-friendly it even has a TortoiseHg client, for whatever that's worth. Jan 11, The changes to the script itself were fairly small. This hook can access the metadata associated with the almost-added changesets, but it should not do anything permanent with this data. This plugin is currently intended to support Mercurial 1. Abort on fatal error hooks use the peculiar convention of returning a true value to indicate failure. Read more. As it turned out the setup was fine, but in an act of desperation I decided to restart kallithea daemon which was nowhere in the documentation , basically thinking 'what could go wrong' - and that did the trick! While this hook is running, if other Mercurial processes access this repository, they will be able to see the almost-new changeset as if it is permanent. Mercurial lets you do this by adding an extension to the end of a hook's name. This is run before starting to transmit a group of changesets from this repository. Hooks that trigger on these events have the added ability to choose whether the activity can continue, or will abort. For example:. This hook can be used to automatically vet a group of changesets.
