When I give it
one,
You may use -1 as a revision value for getFile to get a
latest revision
of a file.
Regarding getFileRevisions, the following code works for
me:
SVNURL url =
SVNURL.parseURIEncoded("h
ttp://svn.svnkit.com/repos/svnkit/tags/1.1.7");
SVNRepository repos = SVNRepositoryFactory.create(url);
long revision = repos.getLatestRevision();
Collection revisions =
repos.getFileRevisions("README.txt",
(Collection) null, 0, revision);
for (Iterator revs = revisions.iterator(); revs.hasNext();)
{
SVNFileRevision fileRevision = (SVNFileRevision)
revs.next();
System.out.println(fileRevision.getPath() + " :
" +
fileRevision.getRevision());
}
> returns an error saying it's not a file.
getFileRevision requires endRevision parameter to be valid
revision in
which file exists, so specifying 0 for the start and valid
revision as
end revision should make it work properly.
Also, getFileRevisions makes server to report file content
for each
revision, so this operation is not effective for just
getting revisions
of a certain file. Alternatively you may use log method:
long revision = repos.getLatestRevision();
Collection logEntries =
repos.log(new String [] {"README.txt"},
(Collection) null, revision, 0, false,
false);
for (Iterator logs = logEntries.iterator(); logs.hasNext();)
{
SVNLogEntry logEntry = (SVNLogEntry) logs.next();
System.out.println(logEntry.getRevision());
}
This is the simplest way to do that, but it could be more
complicated
when file was copied in certain revision (i.e. changed it
path in
repository). Log will report that revision and previous
ones, but to
call getFile on revision before file was copied you'll have
also to know
real file path at that very revision. To get that path you
may use
getLocations(...) method:
Collection logEntries =
repos.log(new String [] {"README.txt"},
(Collection) null, revision, 0, false,
false);
for (Iterator logs = logEntries.iterator(); logs.hasNext();)
{
SVNLogEntry logEntry = (SVNLogEntry) logs.next();
System.out.println(logEntry.getRevision());
// get file path as it was at revision using
getLocations
// pegRevision is revision which we used in log call.
Collection locations =
repos.getLocations("README.txt",
(Collection) null, revision, new
long[] {logEntry.getRevision()});
// as we passed long[1] to getLocations there is only
// one SVNLocationEntry in collection:
SVNLocationEntry location =
(SVNLocationEntry) locations.iterator().next();
System.out.println("path at revision " +
location.getRevision() +
" is: " +
location.getPath());
// now we may call getFile on correct path and
revision:
repos.getFile(
location.getPath(), location.getRevision(), null,
System.out);
}
I've tested above code on README.txt file located in
http://
svn.svnkit.com/repos/svnkit/tags/1.1.7 - history of this
file
includes several copy operations so it demonstrates how path
of the file
could change in different revisions well.
