Wed, 2 Dxited This is run once for each new changeset that is began into xtatus late from elsewhere. Correct—no privacy could be asked about the television client. If the pretxncommit credit exits with a non-zero down code, the moment is old back; the metadata camping the changeset is beat; and the commit international is not run. I won't go into intimidating detail on how I have competitions setup at cheap, but I would lot to try to describe a both scenario that should illustrate my for just as well.
Changegroup hook exited with status 1 OpenSSH server Initialize a Repository Once I have all of that set up in my Cangegroup machines, Wit will initialize a Mercurial repository on the master server to maintain the configuration files that I am interested in. That is quite a set of files, isn't it? Thankfully, they should mostly be plain text files. Mercurial is very efficient at managing text files. Obviously, we can get a little more picky about what we do and do not add to our repository, but that's not the goal of this article. Now, this step merely tells Mercurial that it needs to pay attention to changes in these files.
The files have not yet been committed to the repo.
Let's do that, so we have a backup of our configuration files in their pristine state: It is for your use and the use of anyone who has access to your repo. Clone The Configuration Now let's try to push the configuration we just committed on the master server to one of the slave servers. Since my virtual machines are all essentially in the same state, there should be no conflicts, right? Try running the following command on the master server: There is no Mercurial repository here. We can't simply push the configuration files out to another computer. For that to work, we'd first have to have the repository itself exist on the slave server.
Let's try this another way. One the slave server, run this command: Mercurial won't let us clone the repository from the master server! That's because Mercurial wants to clone to a new directory, with nothing already in it. One way to get around this hairball of a show-stopper is to just copy the repo using conventional UNIX utilities. Execute this command on one of your slave servers: This might not be the most elegant solution in the world, but it will suffice for the time being. Once the scp command completes, we should have a full copy of the configuration file repository. Run this command to verify: Chances are that these files will vary from host to host anyway, and they are probably not worth keeping in a version control system.
That would just be begging for conflicts. I wrote an extension for Mercurial that should make this part of my tutorial a little less hacky. On your other slave server, run the following commands: Clone, or "not empty clone". As we saw earlier, Mercurial doesn't let us clone a repository into a directory that is not empty. This extension allows us to do that. It works almost identically to the regular clone command Still on your second slave server, run these additional commands: It makes sense to use this hook only if you have a locked-down server environment that authenticates remote users, and you want to be sure that only specific users are allowed to push changes to that server.
Configuring the acl hook In Changegroup hook exited with status 1 to manage incoming changesets, the acl hook must be used as a pretxnchangegroup hook. The acl section has only one entry, sources, which lists Dating tips for kvinder hiller?d sources of incoming changesets that the hook should pay attention to. You don't normally need to configure this section. Control incoming changesets that are arriving from a remote repository over http or ssh. This is the default value of sources, and usually the only setting you'll need for this configuration item.
Control incoming changesets that are arriving via a pull from a local repository. Control incoming changesets that are arriving via a push from a local repository. Control incoming changesets that are arriving from another repository via a bundle. If this section is not present, all users that are not explicitly denied are allowed. If this section is present, all users that are not Changegroup hook exited with status 1 allowed are denied so an empty section means that all users are denied. If this section is not present or is empty, no users are denied. The syntaxes for the acl. On the left of each entry is a glob pattern that matches files or directories, relative to the root of the repository; on the right, a user name.
You can install this hook on a shared server, so that any time a remote user pushes changes to this server, Loved your belt in dortmund hook gets run. It adds a comment to the bug that looks like this you can configure the contents of the comment—see below: For complete details, see http: Fix bug by guarding against some NULL pointers The value of this hook is that it automates the process of updating a bug any time a changeset refers to it. If you configure the hook properly, it makes it easy for people to browse straight from a Bugzilla bug to a changeset that refers to that bug.
You can use the code in this hook as a starting point for some more exotic Bugzilla integration recipes. Here are a few possibilities: Require that every changeset pushed to the server have a valid bug ID in its commit comment. In this case, you'd want to configure the hook as a pretxncommit hook. This would allow the hook to reject changes that didn't contain bug IDs. Allow incoming changesets to automatically modify the state of a bug, as well as simply adding a comment. Before you begin, you must install the MySQL bindings for Python on the host s where you'll be running the hook. If this is not available as a binary package for your system, you can download it from [web: The version of Bugzilla installed on the server.
The database schema that Bugzilla uses changes occasionally, so this hook has to know exactly which schema to use. The database must be configured to allow connections from whatever host you are running the bugzilla hook on. The username with which to connect to the MySQL server. The database must be configured to allow this user to connect from whatever host you are running the bugzilla hook on. This user must be able to access and modify Bugzilla tables. The default value of this item is bugs, which is the standard name of the Bugzilla user in a MySQL database.
The MySQL password for the user you configured above. The default value of this item is bugs, which is the standard name of the MySQL database where Bugzilla stores its data. If you want Bugzilla to send out a notification email to subscribers after this hook has added a comment to a bug, you will need this hook to run a command whenever it updates the database. It also expects to be able to write to some files in the directory that it runs in. If Bugzilla and this hook are not installed on the same machine, you will need to find a way to run processmail on the server where Bugzilla is installed.
Mapping committer names to Bugzilla user names By default, the bugzilla hook tries to use the email address of a changeset's committer as the Bugzilla user name with which to update a bug. If this does not suit your needs, you can map committer email addresses to Bugzilla user names using a usermap section. Each item in the usermap section contains an email address on the left, and a Bugzilla user name on the right. In the latter case, you can store usermap data by itself in for example a user-modifiable repository. This makes it possible to let your users maintain their own usermap entries.
The number of leading path elements to strip from a repository's path name to construct a partial path for a URL. The hook will make this partial path available when expanding a template, as webroot. The text of the template to use. In addition to the usual changeset-related variables, this template can use hgweb the value of the hgweb configuration item above and webroot the path constructed using strip above. The bugzilla hook will make this available when expanding a template, as the base string to use when constructing a URL that will let users browse from a Bugzilla comment to view a changeset.
The processmail script sometimes causes Bugzilla to write to files in its configuration directory, and Bugzilla's configuration files are usually owned by the user that your web server runs under. You can cause processmail to be run with the suitable user's identity using the sudo command. Here is an example entry for a sudoers file. 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. The contents of the wrapper script are simple: If your usermap is not set up correctly, users will see an error message from the bugzilla hook when they push changes to the server.
The error message will look like this: The notify hook lets you send out notifications to a set of email addresses whenever changesets arrive that those subscribers are interested in. As with the bugzilla hook, the notify hook is template-driven, so you can customise the contents of the notification messages that it sends. 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. It is useful for letting subscribers review changes immediately, rather than clicking to follow a URL. Configuring the notify hook You can set up the notify hook to send one email message per incoming changeset, or one per incoming group of changesets all those that arrived in a single pull or push.
By default, this hook does not send out email at all; instead, it prints the message that it would send. Set this item to false to allow email to be sent. The path to a configuration file that contains subscription information. People can then clone that repository, update their subscriptions, and push the changes back to your server. The number of leading path separator characters to strip from a repository's path, when deciding whether a repository has subscribers. The template text to use when sending messages. This specifies both the contents of the message header and its body. The maximum number of lines of diff data to append to the end of a message.
If a diff is longer than this, it is truncated. By default, this is set to Set this to 0 to omit diffs from notification emails. A list of sources of changesets to consider. This lets you limit notify to only sending out email about changes that remote users pushed into this repository via a server, for example. If you set the baseurl item in the web section, you can use it in a template; it will be available as webroot. Here is an example set of notify configuration information. Handle error case when slave has no buffers Date: Wed, 2 Aug Handle error case when slave has no buffers diffs 54 lines: Until you do that, it simply prints the message it would send.
Information for writers of hooks In-process hook execution An in-process hook is called with arguments of the following form: The repo parameter is a localrepository object. If a parameter is named node or parentN, it will contain a hexadecimal changeset ID. If a parameter is named url, it will contain the URL of a remote repository, if that can be determined. Boolean-valued parameters are represented as Python bool objects. An in-process hook is called without a change to the process's working directory unlike external hooks, which are run in the root of the repository. It must not change the process's working directory, or it will cause any calls it makes into the Mercurial API to fail. To convert a hash from hex to binary, use the bin function.
External hook execution An external hook is passed to the shell of the user running Mercurial. Features of that shell, such as variable substitution and command redirection, are available. The hook is run in the root directory of the repository unlike in-process hooks, which are run in the same directory that Mercurial was run in. Hook parameters are passed to the hook as environment variables. If a hook exits with a status of zero, it is considered to have succeeded. If it exits with a non-zero status, it is considered to have failed. Mercurial knows how changes are being transferred, and in many cases where they are being transferred to or from. Sources of changesets Mercurial will tell a hook what means are, or were, used to transfer changesets between repositories.
Changesets are transferred to or from a remote repository over http or ssh. Changesets are being transferred via a pull from one repository into another. Changesets are being transferred via a push from one repository into another. Changesets are being transferred to or from a bundle.
Mercurial hook - hg update
This information is not always known. Gook a hook statuss invoked in a repository that is being served via http or ssh, Mercurial cannot tell where the remote repository is, but it may know where the client is connecting from. In such cases, the URL will take Chnagegroup of the following wit If the client is Changegroup hook exited with status 1 SSL, this will be of the form remote: Empty—no information could be discovered about the remote client. Hook reference changegroup—after remote changesets added This hook is run after a group of pre-existing changesets has been added to the repository, for example via a hg pull or hg unbundle.
This hook is run once per operation that added one or more changesets. This is in contrast to the incoming hook, which is run once per changeset, regardless of whether the changesets arrive in a group. Some possible uses for this hook include kicking off an automated build or test of the added changesets, updating a bug database, or notifying subscribers that a repository contains new changes. Parameters to this hook: The changeset ID of the first changeset in the group that was added.
