How can I prevent Subversion commits without comments?

问题

Does anybody know how to prevent commits to a Subversion code repository when there is no commit comment entered?

回答1:

You can use a hook (put it into <repository>/hooks and name it pre-commit.bat (Windows)):

@echo off
::
:: Stops commits that have empty log messages.
::

setlocal

rem Subversion sends through the path to the repository and transaction id
set REPOS=%1
set TXN=%2

rem check for an empty log message
svnlook log %REPOS% -t %TXN% | findstr . > nul
if %errorlevel% gtr 0 (goto err) else exit 0

:err
echo. 1>&2
echo Your commit has been blocked because you didn't give any log message 1>&2
echo Please write a log message describing the purpose of your changes and 1>&2
echo then try committing again. -- Thank you 1>&2
exit 1

Here is a pre-commit hook with @miku's detailed error message for Linux:

#!/bin/sh

REPOS="$1"
TXN="$2"

SVNLOOK=/usr/bin/svnlook
$SVNLOOK log -t "$TXN" "$REPOS" | \
   grep "[a-zA-Z0-9]" > /dev/null

GREP_STATUS=$?
if [ $GREP_STATUS -ne 0 ]
then
    echo "Your commit has been blocked because you didn't give any log message" 1>&2
    echo "Please write a log message describing the purpose of your changes and" 1>&2
    echo "then try committing again. -- Thank you" 1>&2
    exit 1
fi
exit 0

Actually, when you create a Subversion repository, its hooks subdirectory already contains hook samples. Check out the one called pre-commit.tmpl for details on the hook's parameters. It also contains an example for a hook that you're looking for:

#!/bin/sh
REPOS="$1"
TXN="$2"

# Make sure that the log message contains some text.
SVNLOOK=/usr/local/bin/svnlook
$SVNLOOK log -t "$TXN" "$REPOS" | \
   grep "[a-zA-Z0-9]" > /dev/null || exit 1

You can write your hook in any script or language, as long as it's executable on your Subversion machine.

Create a pre-commit hook. Here's some instructions on how to do so yourself, or here is an example hook script that will reject anything with a commit message shorter than 10 characters.

回答5:

Linux script for more than 15 characters--

#!/bin/bash
REPOS="$1"
TXN="$2"
# Make sure that the log message contains some text.
SVNLOOK=/usr/bin/svnlook
# Comments should have more than 5 characters
LOGMSG=$($SVNLOOK log -t "$TXN" "$REPOS" | grep [a-zA-Z0-9] | wc -c)
if [ "$LOGMSG" -lt 15 ];
then
echo -e "Please provide a meaningful comment when committing changes." 1>&2
exit 1
fi

If you are using TortoiseSVN only then you can add TortoiseSVN's property to the root directory: property name: tsvn:logminsize value: 1 This will disable OK button in TortoiseSVN commit window then Message is empty. Please be aware that this property is TortoiseSVN specific it might not work with other SVN client.
