Can Bitbucket automatically create issues from code annotations on commits? - mercurial

I'm looking for a way to automatically create issues within Bitbucket.org for in-code annotations.
E.g. #BUG "Some bug text" should be added as an issue within bitbucket repo when commited.

This is something that should be handled by a hook, and AFAIK, Bitbucket doesn't support those.
You could keep a local mirror that pulls every now and then (using a cronjob) and in a changegroup hook examines the incoming changes, then using Bitbucket's Issues API, creates an issue.

You can discuss and VOTE UP for this feature on bitbucket tracker - Create an issue from a commit message (BB-5107)

How do large companies deal with Mercurial?

I am investigating how to migrate our source control from SVN to Mercurial. One thing I am not sure how to deal with is usernames in commits. From what I've seen, there is no way to force an HG user to use a specific username, even if specified in Mercurial.ini, the user can override it in commits with the -u flag in hg commit.
How do companies deal with this? there is nothing to prevent developer A to commit something in his repository as developer B, and then pushing it to someone else.
Thanks.
I wouldn't say our company is large (4 developers), but it's never been an issue for us so far. I haven't seen any way to prevent that behavior either in my searching. I guess it comes down to an issue of trust amongst your developers.
Unrelated, we did successfully migrate from SVN to Mercurial about two years ago so I may be able to answer other questions you have.
EDIT: An idea:
I'm not sure how you were planning on setting up your topology, but we have a server that functions as the central repository for all our repos. It is possible to push changes between developers (bypassing the central server), but we never do that. We always commit locally and then push/pull from/to the central server. Additionally, we use https and windows authentication to authenticate with this central server.
If you're planning on having something like this, you could create a hook on the server (see repository events) (maybe the precommit event) that would verify that the user name in each commit being pushed is the same as the authenticated user from the web server.
Not sure if this would work, but it sounds plausable.
Another attempt(s)
Path-based ACLs in pseudo-CVCS workflow
If you'll use "controlled anarchy" workflow (p2p communications aren't controlled, resticted AND trusted and single authoritative source is common push-target), you can use "Branch Per Developer" paradigm. I.e - with ACL extension on central repo the following restrictions apply:
Nobody can push to default branch
Each developer can push only in his personal branch (under any name, name means nothing, auth-data for tracking is branch-name)
Only trusted mergers can work with repo-Central (merge dev-branches to default, NO rebase|NO history rewrite in dev-branches)
Each mergeset in default branch contain authentication piece - source branch
Signing branches
If you can't trust (and you must not trust) username in commits, you can trust strong crypto. Mercurial have at least two extensions, which allow digitally sign commits, thus providing accurate (so-so, see notes below) information about the authorship with own advantages and disadvantages in both cases
Commitsigs Extension Wiki and Signing Mercurial Changesets on Windows mini-HowTo are complete enough to understand and demonstrate all aspects of the start. Pro: no additional commits for signing, you can't (by design) sign old historic commits. Contra: not-so-nice output of needed commands (see screenshots in Damian's post for log and verifysigs), because it's GnuPG (no PKI), theoretically it's possible to create and use key-pair for any name-email and only "extra" comparison will show two different keys for one user
GPG extension and Approval Reports from wiki as quick-start. Pro: can use pgp-keys or openssl-certs (TBT!!!) (where openssl means one corporate source of issued certs), more readable and informative output of sigcheck command. Contra:
commiting changes to a .hgsigs file in the root of the working copy
and so it requires extra changesets to be made. This makes it
infeasible to sign all changesets. The .hgsigs file must also be
merged like any other file when branches are merged.
and at last file can be modified by hand by malicious user as any other file in WC
Edit and bugfixing
Openssl can be used in Commitsigs, not GPG extension

How to create disposable experimentation workflow in Mercurial?

Coming originally from SVN, I am still new to Mercurial.
I am interested in creating an experimental workflow to see if I can rewrite a troubled feature from scratch. If my attempt fails though, I wish to delete the experimental workflow - abandoning the work — with nobody else ever seeing it.
The problem is though I still need to push changes of this experimental workflow across laptops and PCs and keep working for a couple of weeks. But still keep the option open to delete that branch and fall back to the main branch, without having any trace of the experimental branch.
Is something like this possible in Mercurial and how could I achieve this?
FYI, I am using mercurialeclipse plugin on Aptana Studio 3.0. (so I
use a UI but commands should be fine too)
After changeset is pushed to the central server (assuming you have one) - there is no way to remove it from there.
So the possible (but terribly inconvenient) solution for you now could be to create a personal separated repository and synchronize your devices using it. And if you like the result - you push to the shared central repo then. Otherwise you just delete the temporary repository.
With a Distributed Version Control System like Mercurial you can sync between any clone of a repository, not just a "central" one that all users have agreed to use.
Therefore, you can:
Clone the repository to private a share that the systems "experimenting" can access.
Clone to a USB key and move that between systems.
Use hg serve to start a web server for a local repository on a system and clone and pull that history to other systems.
Use hg bundle/unbundle to package up new history and email it to another system.
To abandon work, just delete all these extra clones and clone from the common "central" repository again.

Is it possible to add custom field to mercurial log?

we're moving from Subversion to Mercurial now. In Subversion there was possibility to add custom column into log (e.g. bug id) and force user to fill this column on every commit.
Is it possible to implement such feature in Mercurial?
Yes it's possible.
But before you go and do that, why isn't it enough to require bug fix commit messages to uphold to a certain pattern?
i.e. util: rename the util.localpath that uses url to urllocalpath (issue2875) (taken from Mercurial's repo)
Then you can install a hook on your central repository that scans incoming commit messages, and does whatever is needed when that pattern is found.
Furthermore, why would you want to force this on every commit? Is this for a QA team that should only commit bug fixes? If that's the case, a pre-commit hook that greps the commit message for the pattern sounds appropriate.
If you still want the extra field: when Mercurial commits something, it is possible to pass it a dictionary of strings, which you can fill with anything. See the transplant extension on how you might do that. You would also need to wrap the commit command and add a new command line option to it.
But I strongly suggest you think twice before doing this, because aside from the time consuming work involved in coding, testing (and maintaining this between Mercurial releases), you would also need to ensure that it is deployed on every environment where Mercurial is used.

How to monitor "check-in/push-es" to a central Mercurial repository?

If I set up a central Mercurial Repository where certain people are allowed to push to it, what convenient way can I monitor the changes going into that repository?
I'm used to using SVN-Monitor for Subversion. It runs in the task-bar and lets me know whenever something new has been checked in to the repository.
Is there a similar solution for Mercurial ?
This tool looks like it might be what you're after.
Use a RSS feed monitor and point it to the repo's atom/RSS feed (found in the web interface).
Something like this should do nicely: https://superuser.com/questions/9929/rss-notification-in-system-tray
Alternately you could set up a changegroup hook on the repo to be watched and have it trigger something on your system, but polling is probably okay for this.
If you are currently using TeamCity or looking for a Continuous Integration solution:
TeamCity has various apps/plugins like a VisualStudio plugin and Windows TrayIcon for build notifications. You set up a project in TeamCity to build when someone commits to the repository. When someone commits it triggers a build, which will send a notification to you. A bonus is that it tells you if the build succeeded or failed ==> {good code or bad code}
Been giving HgAssist a try it works pretty well.

Tracking a build from Hudson to Mercurial Repo

I'm working on setting up a Hudson/Mercurial stack for development. One of the use cases I have is "As a developer, I want to update my local sandbox to a particular build number from Hudson, so I can [fix a bug, debug issues, create a branched version of code, etc.]."
So, if I see build #49 on Hudson, how do I update my local Mercurial repo to the same source code that was used to build #49?
Note: I have looked at Mercurial tags, however they don't seem quite appropriate. They require a commit, so it seems the commits will dirty up the history (each commit by a developer will show a subsequent commit from the tag operation). If this is the best there is, I guess I will have to live with it, but hoping for something better. Would probably still use tags for releases.
Ok, here's the solution I ended up with:
Using the Description Setter Plugin, I set both the success and failing build description to "Mercurial ${MERCURIAL_REVISION}". Turns out the current Mercurial SCM plugin sets this environment variable to the parent changeset id.
I can then look at a build on Hudson, and if so desired, grab the changeset id and do a "hg update " on my local repo to get that revision of code.
Note that in the Mercurial plugin issue tracker there is some talk of changing this to HG_REVISION instead and adding other environment variables, so this may break at some point in the future, but works for me for now.
You can use the keywords extension on the hudson system to update the nodeid into some aspect of the build, possibly including the artifact names. If the Hudson job output artifacts are like: myproject-2010-02-17-2dbf7575fa46.tar.gz you certainly know how to 'hg update' to that point in time.
The keywords extension and maybe a little ant-fu make that easy to do.
