I have a mercurial repository hosted on bitbucket containing several folders. My goal was to split each of these folder into a separate repository. After trying a few things suggested on stackoverflow, which failed, my last throw of the dice was to replicate a mock example in the bitbucket tutorial
Even though I followed the instructions to the letter, this also failed:
hg convert -s hg -d hg --filemap mymapfile hgsplitpractice hgfreshrepo
initializing destination hgfreshrepo repository
hgsplitpractice is not a local Mercurial repository
abort: hgsplitpractice: missing or unsupported repository
This is the same error that appeared in my previous attempts to split my actual repo.
The questions are:
1. why is this failing?
2. is there any other way to split these repositories?
I was getting the same error as you did.
In my case, the problem was something really silly: I was referring to both repositories by their names instead of specifying their full path.
I hope it helps someone else.
This was failing:
hg convert -s hg -d hg --filemap mymapfile "My-old-repo" "New-repo"
This worked like a charm:
hg convert -s hg -d hg --filemap mymapfile "d:/allrepos/My-old-repo" "d:/allrepos/New-repo"
You can try to use the convert extension.
After the command:
--filemap
you can use:
exclude path/that/you/want/to/split
rename path/that/you/want/to/split .

I'm trying to use mercurial file sets to add all the files in a directory tree, excluding very large files and any binary files. Cribbing from the mercurial documentation, this command should do it:
hg init
hg add 'set: size("<1M") and not binary()'
However this returns a status code of 0, and hasn't added anything to my new, empty repo. I've tried just 'set: not binary()' and that didn't work either.
The frustrating thing is that although I can google for mercurial file sets, and find lots of examples, I can't find anything to help troubleshoot when it doesn't work!
I don't have a .hgignore file, and it's a fresh empty repo. Mercurial 4.2.2.
The directory where I'm testing this has a couple of artificially created files for the purpose of testing. In my real use case, I inherit a multi-gigbyte tarball of assorted sources and binaries from a client, and I want to get all the sources into mercurial before I start hacking to fix their problems, hence the need to exclude the binaries and large files that otherwise choke mercurial.
Here's my little test script:
#!/bin/sh -ex
dd if=/dev/urandom of=binary_1k bs=1 count=1024
dd if=/dev/urandom of=binary_2M bs=1 count=2097152
echo "This. Is, a SMALL text file." > text_small
hexdump binary_1k > text_1k
hexdump binary_2M > text_2M
ls -lh
file binary_1k
file binary_2M
file text_1k
file text_2M
hg init
hg add 'set: size("<1M") and not binary()'
hg status -a
hg add 'set: not binary()'
hg status -a
hg add 'set: size("<1M")'
hg status -a
At the end of this, each status command reports no files in the repo, and the add commands report no errors.
The problem is that file sets do a query of Mercurial's repository data base, which knows only about files that are part of the repository or have been added.
One solution is to add all, and then to get rid of the files that you don't like, e.g.:
hg forget 'set:size(">1M") or binary()'
This works, because the query also requires recently added files, even if they haven't been committed yet.
I push in our repository more big video files, my fault, I did not notice them and forgot to add the folder with the video to ignore file. Now my friends can not upgrade because a shortage of memory (abort: out of memory). How do I remove a video from the master repository? I tried to just delete the folder with the video in /home/hg/project/.hg/ But then do not start updating with an error. Help me pliz and sorry for my english/
See the Mercurial FAQ:
4.14. I committed a change containing nuclear launch codes, how do I delete it permanently?
4.15. I committed a large binary file/files, how do I delete them permanently?
There are some options described on the Editing History page as well.
You:
$ hg rm video.ogv
$ hg ci -m "removed video.ogv"
Other:
$ hg pull your-repository
$ hg update
The HG FAQ merely gives a few vague pointers. Here's how to do it:
Add to your .hgrc:
[extensions]
hgext.convert=
[convert]
hg.saverev=false
Create a filemap of what files you want to remove (myfilemap)
exclude "relative/path/to/file.mp4"
Use hg convert to make a new repo
hg convert --filemap myfilemap myrepo myrepo.new
Now you have the new repo without the excluded files.
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
Mercurial newbie here, I have a simple question.
I deleted one of my files from Mercurial and I want to get it back. I used to do svn up in Subversion, but in Mercurial it doesn't work, I tried hg up, and it does nothing.
I tried hg up to a specific file, and surprisingly (to me..) it told me:
abort: unknown revision '74656d706c617465732f6c6f67696e2e68746d6c'!
I tried to specify a revision and it told me:
abort: please specify just one revision
Isn't there a simple way of doing what I want?
Use hg revert.
hg revert -r REV path/to/file
where REV is the revision of the repository that contains the file you want to recover. See hg help revert for details.
I am working on a system that performs continuous integration and I am looking for a method I can use to get the most recent changeset from a Mercurial repository without creating a repository locally.
I have considered using clone but this method will only work if you have set a working directory locally (since this will be occurring on a build server, I would prefer not to do this because of inclusion of the .hg file and the diffs - all I want is essentially an export of the files from the tip revision and nothing more.)
This request may not even be possible, and it's very likely that I just do not understand DVCS very well. However, if I cannot do what I want to do, is there a workaround?
It's possible using 'hg archive' depending how your remote repository is set up.
If it's available over HTTP using hgweb.cgi or hg serve you can hit the archive link programmatically to get the files you want. Example:
wget https://www.mercurial-scm.org/repo/hg/archive/tip.zip --output-document=- | unzip -
or it's available over ssh:
ssh you#there.com hg archive --type=zip - | unzip -
You can use:
$ hg clone http://your_repo
$ hg archive ../export/
$ rm -rf *
$ cd ..
$ cd export
From Mercurial's help files:
$ hg help archive
hg archive [OPTION]... DEST
create an unversioned archive of a
repository revision
You can use:
http://merc/raw-file
to retrieve a list of files in the repository or
http://merc/raw-file/filename
to get a specific file.
