> DirectUpdateHandler2 has the following code:
> {code}
> if (!cmd.softCommit) {
> synchronized (solrCoreState.getUpdateLock()) { // sync is currently
> needed to prevent preCommit
> // from being called between preSoft and
> // postSoft... see postSoft comments.
> if (ulog != null) ulog.preCommit(cmd);
> }
>
> // SolrCore.verbose("writer.commit() start writer=",writer);
> if (writer.hasUncommittedChanges()) {
> final Map<String,String> commitData = new HashMap<>();
> commitData.put(SolrIndexWriter.COMMIT_TIME_MSEC_KEY,
> String.valueOf(System.currentTimeMillis()));
> writer.setCommitData(commitData);
> writer.commit();
> } else {
> log.info("No uncommitted changes. Skipping IW.commit.");
> }
> // SolrCore.verbose("writer.commit() end");
> numDocsPending.set(0);
> callPostCommitCallbacks();
> } else {
> callPostSoftCommitCallbacks();
> }
> {code}
> As evident in the code above, if cmd.softCommit is true then the post soft
> commit hooks are called first and the actual soft commit happens in a block
> of code after it.
