Graphical changelog in mercurial's hgwebdir.cgi - mercurial

I have a set of mercurial repositories being served online with hgwebdir.cgi. I would like to be able to show a graphical representation of the branches and merges in the same way that this site does. I can't seem to find any reference to how to do that though. Does the functionality only exist in hgweb and not hgwebdir?

This future will be enabled in next release, try use develop version from repo.
In console u can use glog extension

Until version 1.1 comes out (in a few days) you'd need to clone and install from the Mercurial crew respository

Kiln Mercurial Repositories for Versions

we use Kiln with mercurial.
Simplified description we have 2 kind of Repositories.
Some Kind of
"CurrentDevelopment" and repositories for each released version for example 13.1 for the released version 13.1. (There are also user repos and more, like descriped in hginit.com but this can be ignored for the moment)
Now sometimes we need to make a fix to a released version. So we fix it in the Repository for the released version. For 13.1.
Then we cann pull from 13.1 to the currentDevelopment repository
This seems to work fine.
But now we could make something in "CurrentDevelopment" and a month later we recognize that this change will also be needed in 13.1 But I can't pull from CurrentDevelopment to 13.1 because there are a lot of other changes i don't want to have in 13.1
I know this is some kind of "cherry picking" which i isn'T easy realized. But if it wouldn't be many source code i code recode them in 13.1.
But after that when i make changes to 13.1 which i pull to current development i would also pull the changes that are already included in CurrentDevelopment :-/ so in worst case i may get merge failures and duplicate code? I'm not sure if mercurial will safely recognize that this code is also contained.
What is the recommended approach to realise these version specific repositories and handle changes between them ? In especial if a change of the current development repository is afterwards needed in a child verison branch?
The graft mercurial command is your friend here.
It allows you to back-port a change to an old branch.
If your Kiln version is older & doesn't have a version of Mercurial that includes the graft command, you could use the (similar but less reliable) transplant extension.
(graft uses Mercurial's merge logic, transplant just uses the patch logic)
edit...
I don't think that graft command is exposed in the UI of the version of TortoiseHg that is currently bundled with Kiln. See how to use graft in TortoiseHg
The command line should still work though.

Mercurial and online sharing - how to proceed

A noob question... i think
I use Mercurial for my project on my laptop. How do i submit the project to an online server like codeplex?
I'm using tortoisehg and i cant find the upload interface for submit the project online...
From the command line, the command is:
hg push <url>
to push changes a remote repository.
In TortoiseHg, this is accessed through the "Synchronize" function, which seems to show up if you right-click in a Windows Explorer window but not on any file. It's also available in the workbench; the icon is 2 arrows pointing in a circle.
For these things, I find the best way to go is to use the command line interface - TortoiseHG is OK if you need to perform some common operations from the file browser, and it's a nice tool to visualize some aspects of your repository, but it doesn't implement all of mercurial's features in full detail, and it renames and bundles some operations for no apparent reason.
I don't know how things work at codeplex, but I assume it is similar to bitbucket or github, in which case here's what you'd do:
Create an empty repository on the remote end (codeplex / bitbucket / ...).
Find the remote repository's URL - for bitbucket, it is https://bitbucket.org/yourname/project, or ssh://hg#bitbucket.org/yourname/project.
From your local repository, commit all pending changes, then issue the command: hg push {remote_url}, where {remote_url} is the URL of the remote repository. This will push all committed changes from your local repository to the remote repository.
Since the remote's head revision (an empty project) is the same as the first revision in your local copy (because all hg repositories start out empty), mercurial should consider the two repositories related and accept the push.
For an introductory guide to command-line mercurial, I recommend http://hginit.com/

Cloning/Converting Local Perforce Workspace to Mercurial Repo

I'm new to Perforce and Mercurial, so bear with me. I would like to use Mercurial to interface with Perforce in the following way:
I check-out a local Perforce workspace using the P4V client. I then clone a Mercurial repo of that workspace, and use this cloned repo for all my work. When I need updated files, I would first update the local Perforce workspace, and then have the Mercurial repo pull from that. When I'm ready to commit, I push my changes to the local Perforce workspace. Then I use the P4V client to commit my changes in the Perforce workspace to the Perforce depot. Essentially, the local Perforce workspace is a proxy for the Perforce repot.
The reason behind this set-up (versus the common scenario of directly pulling from and pushing to the Perforce repot) is that there is some configuration I need to do via the P4V client (such as mapping/renaming files and directories).
I've looked at the convert and perfarce extensions, but I'm not quite sure they do what I want. They seem to do a one-time conversion, and then thereafter they talk directly to the Perforce repot. Any help would be appreciated.
Convert does an incremental conversion, where it will convert only new changes, but it's unidirectional only (perforce -> mercurial).
I've not looked at the perfarce extension, but it's my understanding that's it's built for a bi-directional, continuous process -- you might want to look at it again.
Alternately, the non-extension options on the Working with Subversion page in the mercurial wiki, details a process for using Mercurial alongside/atop Subversion w/o them interacting in any way except for the file working directory. That's probably very similar to what you're looking to do.
The Perfarce extension should do what you want. I'm also experimenting with a similar setup, and I can pull & push to Perforce quite happily.
I must admit I am having issues with local config files and how they operate in this environment, but there's a couple of other answers here on SO that appear to address this.
I would recommend you give Perfarce a go first, before reverting to anything more manual.

When using Mercurial HG, how to just get the latest code?

I am new to Mercurial HG. My friends created a repo and I am going to use it.
I installed TortoiseHG and trying to get the latest code. I found that when using Clone operation, it will pull all code to my local, including the histories (Am I right?). This is not needed for me. I just wanna get the latest code. Is there an operation for this?
In short, no.
In a bit longer: Mercurial doesn't yet support “shallow” clones where you only get part of the history. So each time you clone you pull in the entire repository with all changesets.
Additionally, unlike Subversion, there is no way to make a “narrow” clone where you only checkout a portion of a repository. For example, if a repository has directories foo/ and bar/, there is no way to get only the bar/ directory. In other words, Mercurial always operates on project-wide snapshots.
The easiest way to achieve what you want:
hg archive [destination folder]
Once you cloned a repository, to get the code of the "tip" (the last version of the current branch - the default one if not precised) you just need to update.
You have an update action in TortoiseHG. Once done, you can look at the files in the folder.
If you wanted another state of the repository (an old version, or an old tagged state) then it's still the update command, with other parametters (see the docs or the TortoiseHG interface).
If you only want the latest code, and you don't intend to do anything related to the repository with it, like commit, or diff to older versions, or whatever, then you it depends on where you got the code from and how.
If he is using one of the hosting services, like bitbucket, there's usually a download link which gives you just the source code.
For instance, if you go here, there's a "Get source" link up and to the right which gives you a few choices in the file format (zip or whatnot.)
If you got the files somewhere else, you need to explore the interface you got them from. Try just pasting the link you cloned from into your browser and see what you get.
Sure. Clone the repository, then delete the .hg subdirectory.
I might be a bit late but actually it is possible to forget some history with Mercurial. You just need to enable convert extension from Your mercurial.ini file or .hgrc file.
[extensions]
hgext.convert=
Now you are able to use convert extension to "clone" only changesets starting from the revision specified.
hg convert --config convert.hg.startrev=[wheretostart] path_to_full_history_repo path_to_new_repo
Just note that this is not the same operation with hg clone. That's why the source repository must be a local repository. For example if we have a repository in folder MyProject and we want to forget all the changes done before revision 100. We can use the following command:
hg convert --config convert.hg.startrev=[100] MyProject MyShrinkedProject
If You are going to use this shrunken repository on a "central server" remember to take care of that everybody clones it before they continue working. Repositories are not compatible with each other anymore.
Mercurial now supports shallow clone using remotefilelog extension. Extension is bundled with mercurial probably since version 4.9. Older versions need to download the extension e.g. from github.
You have to enable it on the server e.g:
[extensions]
remotefilelog =
[remotefilelog]
server = True
serverexpiration = 14
and on client
[extensions]
remotefilelog =
[remotefilelog]
cachepath = /some/path
cachelimit = 5 GB
Than you can do shallow clone with much smaller footprint a and faster clone speed:
hg clone --shallow ssh://user#server/repo

What's the best way to get a copy of the tip of a mercurial repository?

I want to do the equivalent of svn export REMOTE_URL with a mercurial repository. What I want at the end is an unversioned snapshot of the repository at the remote URL, but without cloning all of the changesets over to my local machine.
Also, I want to be able to specify a tag in the remote repository to pick this from. If it's not obvious, I'm building a release management tool that pulls from a canonical mercurial repository to build a release file, and it's slow right now because some projects have large, multiple-version binary files committed.
Is this possible? How would one go about it?
Its usually easier (if the remote HG is using the hgweb interface) to just visit the repo in your browser and download a .tgz / .zip / .bz2 of the tip revision. You'll see the links if the remote HG supports this.
If you want the repository, you need all of the revisions that went into the current tip for it to be at all functional.
There are options to hg clone that allow you to fetch a repository up to a certain revision, but none (that I could find) that allow you to get just the tip revision. What you are essentially asking for is a snapshot of the repo.
Edit: To Get A Snapshot
hg clone http[s]://url.to.repo repo.hg
cd repo.hg
hg archive ../repo-snapshot
cd ..
rm -rf repo.hg
The snapshot is now in repo-snapshot.
Yes, this does entail cloning the repo first, which is why I suggested seeing if the remote hgweb supports on the fly downloads of any particular revision. If it does, your problem is solved with something like curl or wget instead of HG.
If not, its good to let the original repo 'live' since you can update it again later via hg pull, then create another snapshot of a future release. This saves having to start over from scratch when cloning, especially for large repositories with lots of changes.
Also, Linux centric, but you get the gist. Of course, replace http[s] with the desired protocol as needed.
Is there any reason you can't maintain a mirror (updated in the background however often you want) of the remote repository on your local machine, then have the release management tool on your local machine run hg archive out of the local clone as necessary? If your concern is user-responsiveness, and not total bandwidth/storage consumed, this offsets the "slow" part to where you won't see it.
Tim Post noted that if you do have the hgweb CGI interface available, you can configure it to pull compressed archives down and unpack them (and the interface is consistent enough that you could script that via wget), but if you don't, core Mercurial doesn't have a lot of tools to help you, and the developers have expressed an opposition to trying to turn Mercurial into a general rsync-type client.
If you aren't afraid of playing with unofficial add-ons, you could have a look at the FTP Extension. That will force you to push from the server, however.
