How can one access a hidden changeset from a Mercurial server? - mercurial

I have a clone of a remote repository which supports Mercurial topics.
In this version of hg-evolve when the changesets are rebased (for instance) they are hidden.
I need to access the exact working directory at a hidden changeset which I do not have on my local clone. I have verified that other people's clones do have that changeset available via the --hidden flag of most mercurial commands.
I have tried:
hg --hidden clone
hg --hidden pull
but neither seem to have any affect.

Cloning the repository using hg clone --stream will include the hidden changesets, if they're available on the server.

How to keep local changes in Mercurial and make it "invisible"

In my local repo, I have a file A and I made some changes. But I didn't want to submit this changes to remote repo. The question is if I didn't submit this changes in TortoiseHG, everytime I changed other files, A will be listed in the "changelist window".
I know, TortoiseHG has a shelve function. It can store temp files. But files in shelve will revert to origin status.
Commit the change and then modify the phase of the commit to "secret". Note that any child changesets of a secret changeset will also be secret.
hg help phases
You might want to maintain a private branch with these changes - just make the first commit to the branch secret and then periodically merge from the main branch to your private branch.
An alternative is to do the above but without making the changesets secret. This will allow pushing the branch to a central server which gets the benefits of backups, etc and also the possibility that these changes might be useful to other developers (but still not on the main branch).
Consider using Mercurial patch queues to manage local changes. With MQ you can queue up local changes and stash them out of the way for future use.
For the extension's documentation, here's the standard workflow you'd use for putting away local changes for future use:
$ hg qnew choosename
$ hg qpop
$ # ...
$ # restore
$ hg qpush
$ hg strip -k choosename
$ hg qremove choosename
There's also shelve, but I've never used it.

How to clone partially using TortoiseHG "Clone" on bitbucket?

I want to clone part of repository to non-tip changeset, so I use TortoiseHG -> Clone command, enter commit URL and clone. For some reason I get the clone to the last changeset, not that I wanted to clone.
How to clone to old changeset?
I've read that I can do this with git commands. Can I do it with TortoiseHG?
You clone not "commit", but "repository"
If you want to have partial clone, you have to read hg help clone
Procedure and syntax is common to all and any repositories, unrelated to BitBucket
To pull only a subset of changesets, specify one or more revisions
identifiers with -r/--rev or branches with -b/--branch. The resulting
clone will contain only the specified changesets and their ancestors.
hg clone -r <ID> SRC
hg help urls suggests second form of command
hg clone SRC#ID
GUI-way
In case of pure GUI in TortoiseHG "Clone" dialogue, expand "Options" enable "Clone to revision" and define this revision ID

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.

Mercurial Newbie confused

I am familiar with TFS and Vault, but having just started using Mercurial I seem to be getting into a bit of a mess.
Heres what I (think) I've done:
-Created a central repository on bitbucket.org
-On my desktop PC, cloned repository from bitbucket, added files, commit them, push them to bitbucket
-On my laptop, cloned repository from bitbucket, pulled files, added more files, commit them, push them to bitbucket
I've continued to add, edit etc on the different computers.
Now I've noticed that some files from each computer are not in the bitbucket repository, and therefore only in the local repository. No amount of pulling and pushing seems to get it into the bitbucket repository.
What is the most likely thing I've done wrong?
Is there a way to 'force' by changes up to the bitbucket repository?
Did they get into your local repository? I suspect not, i.e. they were new files that were not added to the commit. Use hg add to add them to the changeset before committing or whatever the equivalent is for whatever mercurial interface you're using.
Edit:
Here's the help from Mercurial:
C:\Users\Bert>hg add --help
hg add [OPTION]... [FILE]...
add the specified files on the next commit
Schedule files to be version controlled and added to the repository.
The files will be added to the repository at the next commit. To undo an
add before that, see "hg forget".
If no names are given, add all files to the repository.
...

Telling Mercurial which files to track
Mercurial does not work with files in your repository unless you tell it to manage them. The hg status command will tell you which files Mercurial doesn't know about; it uses a “?” to display such files.
To tell Mercurial to track a file, use the hg add command. Once you have added a file, the entry in the output of hg status for that file changes from “?” to “A”.
$ hg init add-example
$ cd add-example
$ echo a > myfile.txt
$ hg status
? myfile.txt
$ hg add myfile.txt
$ hg status
A myfile.txt
$ hg commit -m 'Added one file'
$ hg status
use "hg -v help add" to show global options

How to apply a collapsed revisions patch to trunk in Mercurial?

I am looking for best practices to do the following:
When I need to implement a feature or fix a bug, I am creating new Mercurial repository from the main one (a trunk).
Then, within some days, or weeks, I am implementing the task in newly created repository, making commits and periodically merging with trunk. After the code in new repository will pass all code reviews, I should provide a repository with all changes collapsed into single revision.
My common way to do this (rdiff extension should be enabled):
hg clone ~/repos/trunk ~/repos/new-collapsed
cd ~/repos/new-collapsed
hg diff ~/repos/new > new.diff
patch -p1 < new.diff
hg commit
This works almost well except when there are binary files present in the changes from ~/repos/new. Another way could be:
hg clone ~/repos/trunk ~/repos/new-collapsed
cd ~/repos/new-collapsed
hg pull ~/repos/new
hg update
hg rollback
then resolve possible conflicts and manually commit the changes
Both ways look for me somewhat ugly and non-native, so I am looking how this operation could be simplified. I've played with rebase extension, but seems its hg rebase --collapse command does not work with workflow described above.
Any ideas are welcome.
Sounds like a good case for mercurial queues.
I do something similar with the histedit extension.
My workflow is something like:
clone a central repo
commit incremental changes to local repo
clone my local repo to make collapsed repo
hg histedit and select/discard/fold the revisions as needed
hg push the collapsed repo to central repo
pull central repo to local or refresh local from scratch
I ensure that my local repo never gets pushed to the central repo by adding an invalid default-push path to the .hg/hgrc file in the local repo root directory.
Solved: Just add
[diff]
git = True
to your hgrc file, and then use my first solution with rdiff extension, replacing patch with hg import:
hg clone ~/repos/trunk ~/repos/new-collapsed
cd ~/repos/new-collapsed
hg diff ~/repos/new > new.diff
hg import new.diff
hg commit
