[~varunthacker],
Roger that!
I have uploaded two patches:
a) WITHOUT FIX and a test-method in {{CdcrBootstrapTest}} to prove tlogs get
copied over to {{target}} when Bootstrap is completed.
b) WITH FIX and test-method in {{CdcrBootstrapTest}} to prove tlogs DOESN'T get
copied over to {{target}} when Bootstrap is completed.
Apart from the changes, I fixed the log lines in {{CdcrBootstrapTest}}, which
was misleading.
PLEASE NOTE: I have wrote the test on top of {{master}} branch and we have
{{debugging}} code from SOLR-11467. If we remove the debugging code and apply
this patch, it won't work. If we commit this and then try to remove SOLR-11467
debugging code, that patch won't work. Please let me know if we need to handle
this in better way or I need to write the patch without SOLR-11467 debugging
patch.

Varun Thacker commented on SOLR-11326:
--
bq. So why even have the option?
Looking at {{CdcrReplicationHandlerTest}} I see when this is used. When the
source replica comes up , it needs all the transaction logs from the leader in
case of leader failure. This also explains why this code exists with default as
"true"
{code}
// fetch list of tlog files only if cdcr is activated
if (solrParams.getBool(TLOG_FILES, true) &&
core.getUpdateHandler().getUpdateLog() != null
&& core.getUpdateHandler().getUpdateLog() instanceof CdcrUpdateLog) {
{code}
So I think the patch is valid.
[~sarkaramr...@gmail.com] can we add a test to make sure this functionality
doesn't break in the future? Maybe we could use a similar mechanism as
{{CdcrReplicationHandlerTest#assertUpdateLogsEquals}} to make sure that a
bootstrap doesn't download any tlogs in the target.
Let's add a test and then we can wrap up this Jira

[jira] [Commented] (SOLR-11326) CDCR bootstrap should not download tlog's from source
[

Varun Thacker commented on SOLR-11326:
--
Is there any scenario where we need to download the tlogs? I don't see any
use-case in master-slave / solrcloud or in cdcr . So why even have the option?
Today in CDCR we explicitly ask the replication handler not to download the
tlogs by doing this
{[solrParams.set(ReplicationHandler.TLOG_FILES, false);}}
But the param is not respected. The patch actually fixes the issue. But why
even keep such an option when we don't need it?
Does someone know the motivation of this in {{ReplicationHander::getFileList}}
{code}
// fetch list of tlog files only if cdcr is activated
if (solrParams.getBool(TLOG_FILES, true) &&
core.getUpdateHandler().getUpdateLog() != null
&& core.getUpdateHandler().getUpdateLog() instanceof CdcrUpdateLog) {
{code}
