Lazarus release engineering

How to merge

The lazarus developers have decided to use the native svn merge for this branch. Other branches used the svnmerge.py script to manage the revisions to be merged.

• TODO: Maybe this information should be put in a separate page.

Using TortoiseSVN

As noted in the link above using TortoiseSVN is more or less self explaining.

• TODO: add some screen shots.

When committing, in the recent messages a nice commit message is available.

Tested with TortoiseSVN 1.7.6, SVN 1.7.4.

Show list of revision that can be merged

In the lazarus fixes_1_0 directory do:

svn mergeinfo ^/trunk --show-revs eligible

Or if you don't have a fixes directory checked out, you can pass the URL path of the fixes branch:

svn mergeinfo ^/trunk http://svn.freepascal.org/svn/lazarus/branches/fixes_1_0 --show-revs eligible

Show list of revision that have been merged

In the lazarus fixes_1_0 directory do:

svn mergeinfo ^/trunk --show-revs merged

Merging revisions from trunk

To merge one or more revisions from trunk, use the svn merge command. For example to merge revision 36506 and 36510 use:

 svn merge -c 36506,36510 ^/trunk

To generate a commit log message, use:

svn log ^/trunk -c 36506,36510 > svnmerge-commit-message.txt

Edit svnmerge-commit-message.txt with your favorite text editor and add a first line like:

Merged revision 36506,36510 from /trunk.

Commit this with:

svn commit -F svnmerge-commit-message.txt

Blocking a revision to be merged

Sometimes you want to block a revision to be merged, i.e. you want to make sure that this revision is never merged to the fixes branch, for example, because it contains a new feature or it contains a version number change not applicable to the fixes branch, but only to trunk. To block revision 36507, use:

svn merge -c 36507 --record-only ^/trunk

Then you can create a log message with:

svn log ^/trunk -c 36507 > svnmerge-commit-message.txt

Edit svnmerge-commit-message.txt with your favorite text editor and add first line like:

Blocked revision 36507 from /trunk

Then commit this change:

svn commit -F svnmerge-commit-message.txt
