would hg remove * when i am at the level of where my local repository copy is , remove it, then of course hg commit and hg push
If you want to completely remove any bindings to Mercurial for a directory containing a repository you can just delete the .hg folder in it. Is that what you mean?

I initially committed my project to a hg repo with the following structure:
myapp/
fizz/
buzz.txt
foobar.cfg
whistlefeather/
vroom-vroom-party-starter.xml
I did so using the following commands:
hg add
hg commit -m "Initial commit."
hg push
I then changed my directory structure locally to look like this:
myapp/
buzz/
fizz.txt
config.foobar
whistlefeather/
vroom-vroom-party-starter.xml
I then ran the same following commands:
hg add
hg commit -m "Changing some things."
hg push
When I go to the remote repo, I see it has the following structure (?!?):
myapp/
fizz/
buzz.txt
buzz/
fizz.txt
foobar.cfg
config.foobar
whistlefeather/
vroom-vroom-party-starter.xml
What commands can I run to push/purge the old directories/files from the remote repo (and so that it reflect the directory struture on my local machine)?
The hg add command you issued prior to your second commit did not actually remove files from under version control, but only added new ones. Now your repository is actually a melange of old and new files.
To add new files and remove missing ones, use hg addremove command or hg commit -A
It's actually simple to remember:
hg add adds files to the repo
hg remove removes files
hg move moves or renames files
hg addremove looks at current working dir and adds and removes files from the repo such that only the files still being present will continue to be tracked.
Each of these operation can be done in any sequence. And only a commit will actually create a changeset
I have got a question regarding suprepositories. Our project is set up like this:
+ projectA
+ some files
+ dependencyA
+ some files
dependencyA is a subrepository. It was created this way:
cd projectA
mkdir dependencyA
cd dependencyA
hg init
hg pull ssh://hg#somerandomiphere/dependencyA
cd ..
echo dependencyA = ssh://hg#somerandomiphere/dependencyA > .hgsub
hg add
hg commit
hg push
If I make changes to the suprepository, then commit and push them from main project. Both of them will be pushed to the server since its recursive. Now my colleague wants to pull changes from the server. But since nothing was changed in the main project, it wont work. But if I change something in the main project and push it to server. Upon hg pull he will get the newest changeset and if he does hg update then, it will update the subrepository as well. This is expected behaviour.
Now my question would be, if there is a way to pull changes, but only for subrepository without making a new clone of it or what would be the best way to do it.
Subrepository in Mercurial wiki, p. 2.5 "Pull"
The 'pull' command is by default not recursive. This is because
Mercurial won't know which subrepos are required until an update to a
specific changeset is requested. The update will pull the requested
subrepositories and changesets on demand. To get pull and update in
one step, use 'pull --update'.
Note that this matches exactly how 'pull' works without
subrepositories, considering that subrepositories lives in the working
directory:
'hg pull' gives you the upstream changesets but doesn't affect your working directory.
'hg update' updates the contents of your working directory (both in the top repo and in all subrepos)
It might be a good idea to always pull with --update if you have any
subrepositories. That will generally ensure that updates not will miss
any changesets and that update thus not will cause any pulls. If the
pull with update fails due to crossing branches then 'hg update' must
be used to get all the subrepository updates.
What was suggested above works like I thought it would. The real problem was my way of creating a subrepository.
Instead of:
cd projectA
mkdir
dependencyA
cd dependencyA
hg init
hg pull ssh://hg#somerandomiphere/dependencyA
It should have been a simple:
hg clone ssh://hg#somerandomiphere/dependencyA dependencyA
As we know .hgsusbtate will lock the subrepo on specific revision after commit. This is what happened, but (!) doing hg pull in subrepository ended with an error
paths cannot contain dot file components
So this means my subrepo was locked on the revision it was updated after commit and it could not pull changes from its repository due to the error shown above. Why this happened is explained pretty well in this accepted answer.
Solution:
cloning is the way to go
I'm starting with Mercurial. I'm reading the mercurial book but still have a question.
I've started my project month ago, and i have a lot of files and directories in it. Now, i want to use Mercurial and made myself an account in bitbucket. Now, i want to set this project up in Bitbucket. How can i add all those files to the bitbucket repo?
This is what i was thinking i could do:
I could try to (1) clone the empty repo (from bitbucket) (1) copy all files into that directory, (3) issue an "hg add" and after that (4) commiting.
Maybe you have a better way to do this.
Thanks!
(1)
hg clone https://ME#bitbucket.org/ME/myproject
(2)
cp existing-project/* myproject/
cd myproject
(3)
hg add
(4)
hg commit -u ME
(5)
hg push (i think i have to do this to make the changes visible)
You can simply hg init, hg add, and hg commit in the original project folder, then edit ~/project/.hg/hgrc to add a default-push location of your bitbucket repo (you can clone it to a temporary folder to get the hgrc created for you which you can copy into your project, even, without needing to RTFM for the right syntax.)
Because of the distributed nature of mercurial, this hgrc entry is the only thing relating your local repo to bitbucket at all; you can even hg push https://ME#bitbucket.org/ME/myproject without making the link explicit anywhere. Each copy of a repository is completely self-sufficient.
Wooble's answer is ok, but it's missing something, so I'm supplementing here.
When you first create an empty repository (by hg init or creating on bitbucket), it has no identity. However, as soon as it has any changesets, it has an identity and you can only push/pull between it and repositories that share that identity.
If you had 2 repositories A and B for separate projects, you wouldn't be able push/pull between them. Once you create a new repository on bitbucket you can push changesets from either A or B to that repo once. If you push changes from B that first time, the bitbucket repository is now related to B. You can't then push changesets from A into it, or pull changesets into A from it.
So when Wooble says,
...this hgrc entry is the only thing relating your local repo to bitbucket at all;
That is correct while it is still empty as it is not related to any repositories until it has changesets. And you still need that address to be able to push/pull between your local repo and the bitbucket repo, but once you've pushed changesets to it it also has that identity that relates it to your local repo.
Following is the scenario: I have a remote Mercurial repository at ssh://remotehost//dir/repo and I am able to clone it to a local host "pandora" in directory /home/user/localrepo/.
Now, I have a superset of this remote repository, where I add my own testing framework, but do not want to merge to the main depot until I am certain it works. So I clone this "local" repo to /home/user/workingdir/ but when I issue the command to do so
$ hg clone /home/user/localrepo/
only the repository folder gets copied none of the files get copied.
I'm not sure what you mean when you say that "only the repo folders gets copied". So there's two things you can try :
Try to do a hg update in your new clone.
List the directory in /home/user/workingdir and if there is a directory name localrepo in it, this is actually your repository. To clone in the current directory, you must do hg clone /home/user/localrepo .
This sounds odd but try a few things:
First in the local repo that you cloned from do a
hg status -A
are all the files that you think should be in there in there? If not are you at the tip of the repo.
You can see what revision you are at with
hg parent
If you want to just go to the tip do hg update
If there still aren't any files listed in the repo do the same to check the one on the server.
If there aren't any files on the server you will need to add all of the files you want mercurial to track, mercurial doesn't automagically start tracking files in the repo location.
(Use hg add --all to add all of the file in the entire directory tree under the repo location.)
If there are files in the local repo, check the testing area and make sure that it is on the proper changeset.
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
