How to strip a mercurial repository - mercurial

I have my converted repo but how do I strip the BitBucket repo that I'll push this converted repo in to?

To strip changesets in a bitbucket repository you need to use the web interface on bitbucket.
First go to your repository on bitbucket, then click on the Settings menu item at the bottom left.
In the settings menu, under the General actions list, you should have a menu item called "Strip changesets", navigate to that.
Then, on the Strip changesets page, input the hash of the changeset you want to strip and click "Preview strip", and go from there.

The link for 'Strip' should probably point to https://www.mercurial-scm.org/wiki/StripExtension .
What it means is probably that you have to run hg strip --keep . on the repository configured into FishEye and then push your rewritten-clone repo into it.

TortoiseHG, fork with subrepos - force commit&push .hgsubstate only

There is public repo on mercurial (not mine). It contains two subrepos. I've made a fork for both main repo nad two subrepos. I want to create pull requests from time to time, but I can't make subrepos work properly.
When I clone my forked repo, it will be downloaded, but two subrepos will remain original, not my forked one. If I'll replace them with forked, I won't be able to make a pull request cos I don't want to switch original repo to my subrepos. But I want to change both repo and subrepo.
Once I've found a solution. I've modified hgrc file in .hg folder of subrepo.
It was:
[paths]
default = ssh://hg#bitbucket.org/originator/subrepo
It become:
[paths]
Me = ssh://hg#bitbucket.org/Me/subrepo
Original = ssh://hg#bitbucket.org/originator/subrepo
It was working exactly as it should. I've changed code, pushed to my subrepo, created pull request for subrepo. Then I've pushed changes in my main repo and it simply worked. .hgsubstate is now reffering to commit that exist on forked repo, but not on original one. When orignator will megre both pull requests, everything would work.
Is I said, it worked before, but not now. For some weird reason I can't just push .hgsubstate that point to new subrepo revision that exists on forked subrepo. I simply can't include it in commit. I click "commit", but in result commit it's not included. And I don't know how to force is being included - HG too "smart" about it. Also TortoiseHG marks my subrepo as dirty. But if I'll try to add both .hgsubstate and my dirty repo, it for some reason tries to push changes to originator's repo. It seems like my HG just can't commit .hgsubstate without pushing changes to subrepo on itself.
Any way to solve this? Everything I want is to commit and push .hgsubstate without doing anything else.
Did you adjust your .hgsub accordingly so that it works for both, your local paths as well as the remote paths to which you push to the server?
It's advisable to add to your .hgsub sections which describe the paths in an absolute sense. I used to struggle with that when I had the subrepos as the same level in the dir structure on the server but wanted them as sub-dirs on my own computer. It helped me to add to .hgsub a subpaths section:
[subpaths]
ssh://user#host.org/path/subrepo1 = ssh://user#host.org/subrepo1
ssh://user#host.org/path/subrepo2 = ssh://user#host.org/subrepo2
/home/user/project/subrepo1 = /home/user/subrepo1
/home/user/project/subrepo2 = /home/user/subrepo2
project/subrepo1 = subrepo1
project/subrepo2 = subrepo2

How to split a patch in MQ by files within the Workbench (no command line)?

The Mercurial Workbench within TortoiseHG allows a graphical use of many mercurial functions. I have a patch sitting in a mercurial queue from which I want to extract some files to another separate patch.
I found a solution here for the command line approach:
Gaol: End up with OP=P1 + P2, where OP=Original Patch, P1=Patch 1, P2=Patch 2
Solution:
hg qpush OP
hg qrefresh <paths to keep> to replace OP with P1, including only the paths you named. The other changes will remain as uncommitted changes in the working directory.
hg qnew -f P2 to pick up those changes.
I simply cannot figure out how to do this within the workbench and would be glad if someone could teach me how to accomplish this. Thanks!
When you use the refresh button in TortoiseHg it acts on the ticked items in the list so to do what you ask you follow the following steps:
Click on your patch OP in the top list
Untick the the files that you want to go into the second patch on the list of changed files on the left
Click the refresh button on the right
Click on the working directory entry on the top list to see the rest of the files
Tick all the files on the list of changes on the left
Click on the new patch button on the right (click on the little down arrow on the commit button if that it's the active button to select the new patch button)
Obviously, enter any commit messages as required.

"Side-Pull" a mercurial repo into main project

I have a repo in my VCS called CodingStandards. In it is a checkstyle.xml file along with findbugs.xml and it will no doubt grow in the future.
What I want to do is in my project FunkyApp is pull CodingStandards into the project and maintain the link to CodingStandards so that if I change it, I can pull & update in my FunkyApp.
Subrepositories are what you are looking for.
However they forces you to have these files in a subdirectory of your project. There's no way to add juste one file to a repository from another.
First of all setup the CodingStandards repo in .hg/hgrc to make life easier
[paths]
default = https://url/FunkyApp
standards = https://url/CodingStandards
Then you can force pull into your repository
hg pull -f standards
This will create two heads in your repo that need to be merged with hg merge and then committed into your main repo.
To be clear CodingStandards will be unchanged. FunkyApp will have all the files from CodingStandards imported in it. Anyone else who clones FunkyApp will get the files without knowing about CodingStandards.

Mercurial subrepo and relative path

I have a project, which I have a bitbucket repository for, and it is dependent on another project that I incorporate as a subrepo. Now, I don't have push access to the subrepository, nor do I want or need to--it's a pull-only relationship.
I realize that when you push the main repository, it will try to push the subrepositories, as well. Since I cannot do that, I pulled a local copy of the dependent project, at the same level as the main repository's directory. In essence, I have the following layout:
Main/ ; pushes to https://mine.org/Main
.hg/
.hgsub
Lib/
SubRepo/ ; clone of Main/../SubRepo/
.hg/
SubRepo/ ; local copy of https://forbidden.org/SubRepo
.hg/
The content of .hgsub is something like,
Lib/SubRepo = ../SubRepo
Then I cloned,
~/path/to/Main $ hg clone ../SubRepo/ Lib/SubRepo
So far, so good. The problem is, after I set this all up and committed the changes, when I try to push Main Mercurial will try to push SubRepo to https://mine.org/SubRepo, which does not exist, thereby failing the whole push operation.
Is there something I'm missing?
Why not just create a https://mine.org/SubRepo -- if you don't want to advertise it you can always turn on hide for it in the [web] section in its .hg/hgrc file. This is the pattern I'm used to, where you clone down the main repo and all the subrepos in the same layout at each place you'll use them: both your development box and your web-facing hgweb install.
Alternately, you could use a [subpaths] section in Main/.hg/hgrc with something like this in it:
[subpaths]
https://mine.org/SubRepo = https://forbidden.org/SubRepo
which should let you intercept the derrived target for the push and point it at a place that which it won't let you push, will let you see nothing has changed so push can continue.
It seems like what Mercurial is doing is legitimate: using the paths listed in your .hgsub it's attempting to push to a directory called 'SubRepo' that exists one level up from Main. This is obviously not what you want, so you'll probably have to work some magic here. I can think of two options:
If you can support this, place the local copy of forbidden.org's repository at C:/Forbidden/Subrepo or something like that, and use this absolute path in your .hgsub. Mercurial will be able to push to this and it should work.
There's no problem including the actual forbidden.org url as your subrepo address if you don't make any modifications to this repo. If there are no changes to the subrepo, your push should succeed. Of course, this is a fairly manual option and on a larger team it would be impossible to enforce. If you did accidentally commit some modification to the subrepo, you'd have to go through and use histedit or MQueues to pull it out, and that can be tricky with subrepos.

Mercurial authenticated pushing problem

We have central repository via http on Apache with digest authentication for two users 'One' and 'Two'.
User 'One' can do:
hg commit -uTwo -mText
hg push http://central-repo/hg/project
How to prevent that fake on the central repository?
Or how to know who makes that push to the central repository?
You can install a pushlog extension to keep track of who pushes what. See the Mozilla hgpoller repo for the pushlog extension they use (they have a separate set of templates as well). An alternative solution would be to write a hook to deny pushing changesets authored by someone else than the authenticating user. Since that can also be a very valid scenario, the pushlog solution might be best.
