How to migrate from fossil to hg - mercurial

I have a fossil repository. How can I migrate the commits to a hg repository. I don't care about issues, wiki, branches.

See a previous answer on this issue
Is it possible to export from Fossil SCM into some other DVCS?
And the following extension should help you in exporting fossil repo to another Mercurial.

Fossil to Git uses the same export/import facility

How to export from mercurial to fossil?

I need something of a bug tracker to manage my small one-person project. I decided to use fossil. My project is on bitbucket mercurial repo. Unfortunately fossil docs contain the information about git to fossil export only.
How can I export (convert) it to fossil?
Fossil can import from Git's fast-export or SVN's dump
In order to import Mercurial repo, you have previously push it to Git (with hg-git) or SVN (with hgsubversion)

Mercurial repository corruption repair says it's not a mercurial repository?

So I have managed to corrupt my mercurial repo. So I am following the steps from the repository corruption page on the wiki to repair it.
When I run the convert command:
hg convert --config convert.hg.ignoreerrors=True REPO REPOFIX
It gives me the following output:
initializing destination REPOFIX repository
REPO does not look like a CVS checkout
REPO does not look like a Git repository
REPO does not look like a Subversion repository
REPO is not a local Mercurial repository
REPO does not look like a darcs repository
REPO does not look like a monotone repository
REPO does not look like a GNU Arch repository
REPO does not look like a Bazaar repository
cannot find required "p4" tool
Why on earth would it say that? And how can I go about fixing it?
It definitely is a mercurial repository, it's hosted on Bitbucket, and I am using Tortoisehg to manage it.
Edit:
I think maybe I can't do this against a remote repository? How can I go about fixing this then?
You probably did not corrupt the remote repository at Bitbucket, did you?
It's more likely you corrupted your local copy, and so you can just clone it from Bitbucket again or try the hg convert … trick on your local copy (i.e. the folder you manage with TortoiseHG).
A bit late but I faced the same issue. The mistake was running that command inside the project folder. You have to run the command outside the folder containing the .hg file. I could not find a way through TortoiseHg console to move up a directory so I used windows terminal.

Embedding a github repository inside a mercurial (kiln) repository - how integrated is it?

Summarised Question:
Are github-hosted sub repositories within a mercurial/kiln repository possible, and if so are they automatically updated/cloned when the parent mercurial repository is operated on by a hg clone or hg commit command?
Detailed Question:
Following on from my question that was answered so excellently here , some of my third party code is in folders I downloaded a while ago from opensource efforts on github. Since at that stage I was not using version control, those folders where just standard folders that now been incorporated as sub repositories in mercurial.
This is obviously not ideal, as for one thing, new versions of the libraries may have bug fixes, or new features I wish to use in the future. I also may need to locally customise some of the libraries.
I can see from reading this link that it possible to have mercurial "know" about those git server urls (and revisions), so I can then have mercurial clone the github hosted libraries direct from their parent repos.
Am I right in saying that when I clone the parent (mercurial) repos, those files will be pulled from github, without having to separately manage this using git?
What is also not clear is, if I were to do this, and it transpired that code might need to be customized from within that github-cloned repository, would I need to use git to manage revisions of the local files, or would mercurial do that by proxy? eg id I were to hg commit -S would mercurial invoke git on my behalf to handle that?

Yes, clone of a Mercurial repository that contain subrepositories will trigger a clone of the subrepos too. It really happens on update. Mercurial notices the .hgsub file and issues the needed hg clone and git clone commands for you. It uses the information in .hgsubstate to know exactly what revision to checkout.
The subrepositories can be hosted anywhere. For a Git subrepository declared like
foo = [git]https://github.com/user/repo.git
Mercurial will simply issue the corresponding clone command:
git clone https://github.com/user/repo.git foo
It's then your reponsibility to later go into the foo repo and use Git to fetch new commits as necessary. After you fetch/pull new commits, you can make a top-level commit to record the new state of the subrepo in the .hgsubstate file. Use hg summary to see if a subrepo is dirty in this sense.
[...] would I need to use git to manage revisions of the local files, or would mercurial do that by proxy? eg id I were to hg commit -S would mercurial invoke git on my behalf to handle that?
When you edit files and make a top-level hg commit, Mercurial will make sure to commit the subrepo first (if you use hg commit -S or if ui.commitsubrepos=True). If you make a top-level push, then Mercurial will always push the subrepos first so that you always have a consistent set of changes on your server.

Transplanting mercurial changeset onto hgsubversion converted repository

I have been migrating from subversion to mercurial piecemeal and this has created a bit of a tangle. I had an old SVN server (pre 1.4) to start with so here is what happened.
HgSubversion did not want to pull in the full history from trunk, so I did a shallow convert.
My colleagues did their last commits to SVN and I pulled those into Hg.
We moved over to Hg and started pushing to it
Just to be safe one of my colleagues made some more commits to SVN.
I managed upgrade the SVN server and get the full repo to the new SVN.
HgSubversion pulled in the full history successfully - including the few extra/duplicate commits.
Now I would like to "transplant" the commits in the shallow mercurial repository into the full history, the repositories are related in content but unrelated in mercurial hashes.Short of just copy pasting content what would be the best way to migrate the changes ? Eventually everybody should be able:
To switch the Hg repo with full history and keep working
Have automated push from the Hg repos of suitable squashed/rebased changesets to SVN as a service user.
I would like a concrete example with the following scenario.
Last mercurial hash at step 2 - A
Current mercurial hash after pushes step 3 - B
Hash of last commit after pull from upgraded SVN - C
Hash of step 2 commit after full SVN history pull - D
I am not very good at ASCII art, feel free to add one for bonus points.
We did a CVS -> Mercurial migration last week at work. Like in your case, some people continued to use the CVS for a time.
In order to sync the the two repositories when the CVS server was finally shutdown, I did the following :
Convert the CVS to mercurial via cvs2hg
Export each new revision with hg export
Import the patch files with hg patch
There was only a dozen revisions, so this was no big deal... If you have many more revisions, you could maybe take a look at the transplant extension.
Hope this helps.

where is mercurial official repository

The official mercurial web page can't find the entry of official repository, only download links, where is it, thanks.
The official Mercurial page lists two repositories for getting the Mercurial source:
The hg-stable repository leads to stable releases.
The hg repository is the main development repository
If you need a mercurial repository, try bitbucket.org. If you're looking for the development snapshot of mercurlial try the developer repos.
