Description
WIP SJ:
There are most cases where an editor may seems ready to be used but actually doesn't.
Behavior may be problematic according to the duration of the parents branch computing or duration of the result computing itself.
- a) reopening a persisted result when its parent branch is not ready
- b) computing a complex result
In both of these cases, if the duration is too long, the editor widget should be disabled or not opened before the computing has ended.
Otherwise, user can change parameters and run a compute leading to wrong result or simply some crashes due of various reasons.
Example of bug 1¶
There is a bug in 0.8.0 where the index of partition found nothing if the parent partition parts are not computed yet, typically when reopening TXM.
More information: the problem here is important. When creating an index of partition, the editor opens and the parent and children of parent are computed in background. But since the editor is ready, if we type eg. "faire" before the parts are computed, nothing is found in the index.
Steps to reproduce¶
=> have a Partition based on a complex query, eg. ELTECFRAORIG_sp_n
=> launch TXM execute Index with "faire" query
=> the editor and console return no results
Solutions to restrict and/or avoid the behavior of case a)¶
- ensure the computing of parents branch is done before displaying the editor
SJ: solution has been implemented by running a modal cancelable dialog to block the UI until the needed parents branch is computed.
The editor is not displayed until the process has ended.NOTE: later, it would be nice to manage a blocking state only for the concerned branch, so the user can still use TXM on other corpora or branches
New issue for this improvement and validation tests: #2746.
Solutions to restrict and/or avoid the behavior of case b)¶
- 1) permit only one compute at a time in TXMEditor.Compute() by storing the current computing Job and returns if it's already running
=> will avoid the possibility to get some wrong results when the Partition is not yet computed (eg. typing "faire" in an Index does not return empty result anymore, atm this message is displayed in the console: "Editor is already computing .... Please wait or abort the computing job (Calcul de Index de partition: ELTECFRAORIG_sp_n: ...…).")
=> It doesn't avoid to open another Index
SJ: this solution 1 has been implemented. Need to translate the log.
* 2) on computing, find a way to disable the editor widgets (or computing button) so the user can not start parallel computing
New issue for about this point here: #2747.
Validation tests¶
- create and compute a complex result
- while computing, change some parameters and click on compute button
=> it should display a console alert
=> when the first compute has ended, the parameter widget values must match the parameters used by the first compute

Need to do a new issue about the cqpjni multi-thread access and maybe about the transfer of C++ errors to Java exceptions.
Using synchronized in MemCqiClient may help to reduce crash due to multi-thread access:
@Override
public synchronized void cqpQuery(String arg0, String arg1, String arg2)
throws IOException, UnexpectedAnswerException, CqiServerError {
if (arg0 == null || arg1 == null || arg2 == null) {
throw new CqiServerError("cqpQuery called with NULL parameter.");
}
Boolean ret = server.cqpQuery(arg0, arg1, arg2);
// System.out.println("CQPSERVER return: "+ret);
if (ret == null || !ret) {
int e = server.getErrorCode();
// System.out.println("throw exception with cqp error code: "+e);
throwExceptionFromCqi(e);
}
}
