But I failed to find the place where the code I am looking for was checked in, instead I discovered an old working copy (from CVS) on my disk where the file I was looking at actually *had* the changes I was trying to find... But looking in SVN both sides of the timestamp of the file failed to get any commit with the changed code. So the conclusion is that that particular code section which should have fixed the bug back in 2015 was actually not checked in to CVS and hence did not reach SVN a couple of years later. So the binary in that working copy worked as it should whereas all following compiles (that were part of the transfer to Delphi XE5 vis SVN) did not since they were based on fresh checkouts Looks like an oversight at the time... -- Bo Berglund Developer in Sweden

But since you use TortoiseSVN I might suggest that you look at Tortoise’s graphical Blame. It looks much like the command line client in that you get the revision number each line was changed but you can right click a revision number and “blame previous revision” which will give the previous time that line was changed.

Blame isn't always the right solution, but if you know which line is the problem, it can tell you when that line last changed. But it sounds like your problem is more complicated and arose from multiple commits.

But that is not what I want, instead I want to know *all* revisions in which the file was modified so I can look at these revisions and see what changed between them concerning the function I want to inspect. If I could get the rev numbers at the beginning of each result line in numerical order and nothing else I would be done with the list. with this command: svn log -q https://svnserver/svn/pc/AgiSSAdmin/trunk/Source/class_SuperSting.pas > log.txt I got a file containing a reverse ordered list of revisions looking like this: r200 | bosse | 2001-06-24 17:29:47 +0200 (Sun, 24 Jun 2001) r197 | bosse | 2001-06-23 12:12:37 +0200 (Sat, 23 Jun 2001) with 106 revisions present. So log is the better solution. Now I need to figure out how to best attack this analysis with so many commits... -- Bo Berglund Developer in Sweden

Some things that might be helpful:
(1) The '--quiet' (or '-q') switch to 'svn log', together with the
as mentioned by Robert, e.g.,:
$ svn log --quiet
Using the INSTALL file in a working copy of Subversion's sources as an example:
$ svn log --quiet INSTALL

(2) The '--revision' (or '-r') switch with a {DATE} (or {DATE}:{DATE}
range) instead of a revision number. For example, with the same
INSTALL file, if I want to see the changes made in 2014:
$ svn log --quiet --revision {2014-01-01}:{2014-12-31} INSTALL
