    <p>I'm relatively new to Mercurial and my team is trying it out right now as a replacement for Subversion. </p> <p>How can I commit and push a single file out to another repository while leaving other modifications in my working directory uncommitted (or at least not pushed to the other repository)?</p> <p>This happens for us with database migrations. We want to commit the migration to source control so a DBA can view and edit it while we're working on the code modifications to go along with that database migration. The changes aren't yet ready to go so we don't want to push all of them out.</p> <p>In subversion, I'd simply do:</p> <pre><code>svn add my_migration.sql # commit only the migration, but not the other files I'm working on svn commit -m "migration notes" my_mygration.sql </code></pre> <p>and continue working locally.</p> <p>This doesn't work with mercurial as when I'm pushing it out to the other repository, if there are changes to it that I haven't pulled down, it wants me to pull them down, merge them, and commit that merge to the repository. Commits after a merge don't allow you to omit files so it forces you to commit everything in your local repository.</p> <p>The easiest thing that I can figure out is to commit the file to my local repository, clone my local repository, fetch any new changes from the actual repository, merge them and commit that merge, and them push my changes out.</p> <pre><code>hg add my_migration.sql hg commit -m "migration notes" my_migration.sql cd .. hg clone project project-clone cd project-clone hg fetch http://hg/project hg push http://hg/project </code></pre> <p>This works, but it feels like I'm missing something easier, some way to tell mercurial to ignore the files already in my working directory, just do the merge and send the files along. I suspect mercurial queues can do this, but I don't fully grok mq yet.</p> <p>Thanks to Josh Matthews below, the shelve command is exactly what I'm looking for. I didn't see any great install instructions with some googling, so here is the combined stuff I used to get it working:</p> <p>Get it with:</p> <pre><code>hg clone http://freehg.org/u/tksoh/hgshelve/ hgshelve </code></pre> <p>The only file (currently) in the project is the hgshelve.py file.</p> <p>Modify your ~/.hgrc to add the shelve extension, pointing to where you cloned the repo:</p> <pre><code>[extensions] hgshelve=/Users/ted/Documents/workspace/hgshelve/hgshelve.py </code></pre> <p>Then you can <code>hg shelve</code> and <code>hg unshelve</code> to temporarily store changes away. It lets you work at the "patch hunk" level to pick and choose the items to shelve away. It didn't appear to shelve a file had listed for adding, only files already in the repo with modifications.</p>

    1. COthis is one feature that I really value in git (i use it all the time), and would make it hard for me to switch...

    2. COThis isn't actually how I'd do things now that I've learned a lot more about hg. Now I'd commit the changes locally, update back to the previous revision and do my changes there and "hg push --rev ." to nudge out only the current branch. Then update back to the other work and continue there. If I decided I didn't want that work anymore, I'd just "hg strip" it out. Much easier and you don't need to worry about rejected hunks of files, everything is tracked and in source control.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
