Seeking possible reason for error by diff -r PREV
Hi,
I got an error with diff command. When I used "svn diff -r PREV file.cpp", I got the following error.
svn: REPORT request failed on '/svnroot/・・・/file.cpp'
svn: File not found: revision 10838, path '/・・・/file.cpp'
I checked log of the file.cpp and the revisions in the logs look:
r17535
r16730
r16152
r14113
r13155
r12709
r12130
r11114 <- this is the first ci of this file
Btw the BASE is 20422. Where did revision 10838 in the error message come from?
So I thought that the diff command (diff -r PREV file.cpp) would compare r16730(PREV) and BASE.
How can I look into the problem to find out why this happened?
Thanks,
Kotaro

Wrong. The first log entries may show branching, or in general the copying of
a parent directory of file.cpp. How you can locate direct changes on file.cpp
with "svn log", I don't know. I guess "svn log file.cpp -v" and find the
direct change in the change list. Incidentally, "svn log -r COMMITTED
configure@HEAD" doesn't work for me either, but I guess svn log simply
doesn't bother to trace the path from the peg revision.
"svn info -r COMMITTED file.cpp" is probably the quickest way and works fine
for me, both on svn 1.6.5 and 1.4.2. As does "svn diff -r PREV file.cpp".
Barring wiser advise on the list, I think your repository is corrupt. I would
"svnadmin dump" and load it somewhere else to figure that out.

The followings are some more info on this.
"svn info -r base file.cpp" prints r20422.
"svn info -r committed file.cpp" prints:
svn: REPORT request failed on '/svnroot/dir-0/!svn/bc/20422/dirs-m/dir-n/file.cpp'
svn: File not found: revision 10838, path '/dirs-m/info/file.cpp'
"svn info -r prev file.cpp" prints the same as the committed.
I know there is no '/dirs-m/info/file.cpp' in r10838 but the command refers to r10838 somehow.

One of the numerically-named files under the directory $PATH_TO_REPOS/db/revs/.

Did you mean a dump file of the repository? What is the "revision file" exactly?

If there are just a few occurrences, set up a pre-revprop-change hook
to allow you to change revision properties. Then use "svn propset --
revprop -rREV svn:author AUTHOR" to set the author of revision "REV"
to "AUTHOR". If there are many, you could write a script to automate
this. You can remove the pre-revprop-change hook after you're done,
unless you want to continue to allow people to edit revision properties.
Another option is to dump the repository with "svnadmin dump", then
use svndumptool to transform the svn:author revprop as needed, then
"svnadmin load" that into a new repository. This would involve the
inconvenience of having your repository offline, and could take a long
time, depending on how much data is in the repository. So probably
you'll just want to use "svn propset" (or "svn propedit") as above.

Changing a commit username
Posted by Jake Stone <ja...@gmail.com>.
Hello!
Our svn server is running on Apache with LDAP authentication, and until
recently any username was "DOMAIN/user" - we decided this was
unnecessary since there was only one domain. A quick change to the
server and usernames became just "user" The problem is, there are
several commit made to the repository before this happened. Is it
possible to replace these name in the repository? I would like to
replace any instances of "DOMAIN/user" with "user" so searches by commit
name, etc work as expected.
One user also had an incorrectly spelled username, and we have the same
problem.
Thanks!

I'm not sure how that last part is relevant (maybe I missed something
else in the thread). 'svn diff' and 'svn log' don't take the same
paths through the repository backend.

If 'svnadmin verify' didn't fail, you may be okay (although if you're
using a more recent version of svn, I believe it's regressed in some
regards).

Hi John and Stein,
Thanks for the reply.
I tryied "svn log file.cpp -l 1" and it returned r17535.
I have not dump the repos but did "svnadmin verify" and it returned no error.
Thanks,

Even so, in this case the COMMITTED should be r17535 (bcz "svn log file.cpp" prints r17535 first) and the PREV should be r16730 or r17534 like you said. I am not so sure which of the version svn takes for "diff -r PREV file.cpp" though.

'svnadmin verify' or 'svnadmin dump' should help verify the integrity
of the repository. See what it says. I've seen a few revisions in
the past where a file was expected to be changed in a prior revision,
but the noderev and change entry was missing from that revision.

Thanks Stein.
The svn version is 1.4.2 and the server is 1.4.0.
I have not tried yet but "svn log --limit 1 file.cpp" will return r17535 since "--limit" just limits the number of lines displayed, no? Even so, in this case the COMMITTED should be r17535 (bcz "svn log file.cpp" prints r17535 first) and the PREV should be r16730 or r17534 like you said. I am not so sure which of the version svn takes for "diff -r PREV file.cpp" though.
I would like to know a reason why this happens and to fix it if this happens because of a corrupted repository. Any ideas?

Well you can look in the files under the .svn directories. But since you just
checked out, there's nothing useful there that isn't in the repository.
Unless you have an unreliable disk/memory/system, but then I doubt you'd get
to this point without other errors.
I've never used "-r PREV" and use TortoiseSVN for inspecting history. But
from what I read and see, if "svn log file.cpp -l 1" prints r17535 as the
last change, then PREV for that file is r17534 and that's what "svn diff -r
PREV file.cpp" should be looking at. What is your "svn --version" anyway?

Thanks for the reply.
This happens just after the working copy created. My novice quesiton is that evenry info came from the repository after check out.
Is there a way to look into the working copy?

It's a shot in the dark with an empty water pistol, but maybe svnversion
reports it as the oldest revision somewhere in the working copy.
