How to display a specific user's commits in svn log?

Question

How to display a specific user's commits in svn? I didn't find any switches for that for svn log.

Answer 1

You could use this:

svn log | sed -n '/USERNAME/,/-----$/ p' 

It will show you every commit made by the specified user (USERNAME).

UPDATE

As suggested by @bahrep, subversion 1.8 comes with a --search option.

Answer 2

With Subversion 1.8 or later:

svn log --search johnsmith77 -l 50

Besides author matches, this will also turn up SVN commits that contain that username in the commit message, which shouldn't happen if your username is not a common word.

The -l 50 will limit the search to the latest 50 entries.

--search ARG

Filters log messages to show only those that match the search pattern ARG.

Log messages are displayed only if the provided search pattern matches any of the author, date, log message text (unless --quiet is used), or, if the --verbose option is also provided, a changed path.

If multiple --search options are provided, a log message is shown if it matches any of the provided search patterns.

If --limit is used, it restricts the number of log messages searched, rather than restricting the output to a particular number of matching log messages.

Answer 3

svn doesn't come with built-in options for this. It does have an svn log --xml option, to allow you to parse the output yourself, and get the interesting parts.

You can write a script to parse it, for example, in Python 2.6:

import sys
from xml.etree.ElementTree import iterparse, dump

author = sys.argv[1]
iparse = iterparse(sys.stdin, ['start', 'end'])

for event, elem in iparse:
    if event == 'start' and elem.tag == 'log':
        logNode = elem
        break

logentries = (elem for event, elem in iparse
                   if event == 'end' and elem.tag == 'logentry')

for logentry in logentries:
    if logentry.find('author').text == author:
        dump(logentry)
    logNode.remove(logentry)

If you save the above as svnLogStripByAuthor.py, you could call it as:

svn log --xml other-options | svnLogStripByAuthor.py user

Answer 4

Since everyone seems to be leaning toward linux (et al): Here is the Windows equivalent:

svn log [SVNPath]|find "USERNAME"

Answer 5

svn log | grep user

works for the most part.

Or to be more accurate:

svn log | egrep 'r[0-9]+ \| user \|'

Answer 6

While yvoyer's solution works fine, here is one making use of SVN's XML output, parsing it with xmlstarlet.

svn log --xml | xmlstarlet sel -t -m 'log/logentry' \
  --if "author = '<AUTHOR>'" \
  -v "concat('Revision ', @revision, ' ', date)" -n -v msg -n -n

From here you could go into more advanced XML queries.

Answer 7

Here’s my solution using xslt. Unfortunately, though, xsltproc is not a streaming processor, so you have to give log a limit. Example usage:

svn log -v --xml --limit=500  | xsltproc --stringparam author yonran /path/to/svnLogFilter.xslt  - | xsltproc /path/to/svnLogText.xslt  - | less

svnLogFilter.xslt

<!--
svnLogFilter.xslt

Usage: (note: use double dashes; I can't do double dashes in a XML comment)
svn log -xml | xsltproc -stringparam author yonran svnLogFilter.xslt -
-->

Answer 8

Beginning with Subversion 1.8, you can use --search and --search-and command-line options with svn log command.

So it should be as simple as running svn log --search JohnDoe.

Answer 9

You can use Perl to filter the log by username and maintain the commit messages. Just set the $/ variable which decides what constitutes a "line" in Perl. If you set this to the separator of the entries of the SVN log, Perl will read one record at a time and then you should be able to match the the username in the entire record. See below:

svn log | perl -ne 'BEGIN{$/="------------------------------------------------------------------------"} print if /USERNAME/'

Answer 10

To GET diffs along with the checkin.

Get the revision numbers into a file:

svn log | sed -n '/USERNAME/,/-----$/ p'| grep "^r" 

Now read through the file & executing diff for each revision:

while read p; do   svn log -v"$p" --diff ; done < Revisions.txt 

Answer 11

I had write a script by Python:

#!/usr/bin/python
# coding:utf-8

import sys

argv_len = len(sys.argv)


def help():
    print 'Filter svnlog by user or date!       '
    print 'USEAGE: svnlog [ARGs]                '
    print 'ARGs:                                '
    print '    -n[=name]:                       '
    print '      filter by the special [=name]\n'
    print '    -t[=date]:                       '
    print '      filter by the special [=date]  '
    print 'EXP:                                 '
    print '1. Filter ruikye\'s commit log       \n'
    print '     svn log -l 50 | svnlog -n=ruikye\n'


if not argv_len - 1:
    help()
    quit()

author = ''
date = ''

for index in range(1, argv_len):
    argv = sys.argv[index]
    if argv.startswith('-n='):
        author = argv.replace('-n=', '')
    elif argv.startswith('-t='):
        date = argv.replace('-t=', '')
    else:
        help()
        quit()

if author == '' and date == '':
    help()
    quit()


SPLIT_LINE =
    '------------------------------------------------------------------------'
src = ''.join(sys.stdin.readlines()).replace('\n\n', '\n')
lines = src.split(SPLIT_LINE)

for line in lines:
    if author in line and date in line:
        print SPLIT_LINE, line

if len(lines):
    print SPLIT_LINE

and use:

$ mv svnlog.py svnlog          

$ chmod a+x svnlog             

$ cd /usr/local/bin
$ ln -s ~/mycmd/svnlog filter 

$ svn log | filter -n=ruikye -t=2015-03-04
