83e6d761dd- Increase the initial delay for "checkAndDeleteOldFiles" to 54 hours, in order to avoid obsolete checks earlier, since a directory needs to have been last accessed at least 48 hours ago, while some additional hours are needed for the first batch to be finished. - Improve a log-message.Lampros Smyrnaios2024-12-05 17:56:15 +0200
fa7b2da926Make sure the "already-retrieved" fulltexts are deleted as early as possible. These are the files which have their hash been added in the Database sometime in the past and the Controller has not requested them now.Lampros Smyrnaios2024-12-04 00:59:00 +0200
bb521cc493Update the logic behind sending the "shutdownReport" to the Controller: - Make sure the Controller is being informed for the about-to-shut-down state of the worker, even if it is being shut-down without the use of the api. - Send the report as late as possible, in order for the Controller to know the exact time the Worker was shutdown.Lampros Smyrnaios2024-12-04 00:45:22 +0200

d630f16198Improve the compression of fulltext files: - Fix not using the big bufferSize it was supposed to use. - Make sure the maximum compression-level is used. Before, the invalid value "bufferSize" was passed as the level, and it is unclear to which real-compression level it was changed to, inside the zstd-library (19 or 22 (only allowed though "ultra mode")), probably to the ultra-level though, as this "switch" seems to be required only through the cli. - Exclude the possibly outdated "commons-compress" transitive dependency from the "publications_retriever" dependency.Lampros Smyrnaios2024-06-10 18:21:35 +0300
107908a733- Fix not deleting the "assignments_*" directory, along with the potentially partially created zstd file, in case there was a compression error. - Show the number of files which were successfully compressed, in each batch. - Fix the class-value used in the Logger-initializer, in "FullTextsController". - Improve an error-log.Lampros Smyrnaios2024-05-30 12:29:02 +0300

9073f56227Revert the "read-timeout" value back to 1 hour, as there is no that big of a problem with the load of either server, it's a frequent network-"lag" that causes the issue, which is not solved even with 2 hours of waiting.Lampros Smyrnaios2023-10-31 15:08:57 +0200
69ea5b6d19- Increase the "ReadTimeout" to 2 hours, as the Worker struggles to get the assignments-data in time. - Revert the change about special handling of the "RestClientException". The exMsg was appearing in a different line, in the logs, and was a "SocketTimeoutException".
2.1.5
Lampros Smyrnaios2023-10-27 18:39:10 +0300
bfa76e9484- Show the full stacktrace in the weird case of a "RestClientException" without an exception-message. Also, in this case, retry immediately, as there is no long-lasting network problem that requires some time between requests, but most probably a random interruption. - Code polishing.Lampros Smyrnaios2023-10-27 17:36:54 +0300
1b45f384a7- In case a faulty "assignmentsCounter" was given to the "addReportResultToWorker"-endpoint, then return an explanatory error-message along with the HTTP-404 error. - Update Gradle.Lampros Smyrnaios2023-10-06 15:45:53 +0300

9c897b8bf4- Make use of the new Normalizer utilized by the PublicationRetriever plugin. - Code polishing.Lampros Smyrnaios2023-06-10 02:40:45 +0300
2aedae2367- In case a serious error happened while processing the assignments, instead of shutting down immediately, now the Worker shuts down the executor service, registers that it will shut down soon and waits for the Controller to retrieve the already downloaded full-text files. - In case the full-texts' subdirectory could not be created, then terminate the "handleAssignment" method immediately. No posting of a faulty workerReport to the Controller should happen. - Code polishing.Lampros Smyrnaios2023-05-31 15:25:36 +0300
4a95826f58- Avoid processing the assignments, for which the assignments_full-texts subdirectory cannot be created. - Avoid a double-log.Lampros Smyrnaios2023-05-31 02:27:24 +0300

903032f454- After a WorkerReport has been sent, ask for new assignments immediately. So, the Worker does not have to wait for hours for the Controller to check for duplicate files in the DB, retrieve and upload the full-texts and insert the records to the DB. - Special care is taken to delete the delivered full-texts as soon as possible. - Write the workerReport to a json-file, in case something goes wrong, and keep it until the Controller notifies the Worker that the processing was successful.Lampros Smyrnaios2023-05-23 22:19:41 +0300
9cb43b3d94- Improve startup speed, by using a faster remote server to get the host's machine public IP. This also reduces the risk of not being able to get the public IP at all. - Set the App to gracefully shut down the WebServer and wait up to 2 minutes. - Increase the waiting time for the "PublicationsRetriever.executor" to shut down, to 2 minutes.Lampros Smyrnaios2023-05-23 20:17:58 +0300
4d90846261- In case the specified "controllerIP" is actually a domain-name, find its IP-address, so that a proper IP-to-IP comparison can be performed and the "securityChecks" can pass. - Increase the "read-timeout" when searching for the host's machine public-IP. - Update dependencies. - Code polishing.Lampros Smyrnaios2023-05-22 21:25:22 +0300

d5a997ad3dUse restTemplates with different read timeouts depending on the operation. For the assignments-request we need a shorter read timeout, than the one we need for the worker-report. This guarantees that the connection does not hungs for so long, when the Controller crashes before sending the assignments.Lampros Smyrnaios2023-04-29 17:24:16 +0300
0ba15dd31aIncrease the "requestReadTimeoutDuration" to 10 hours, as the number of full-texts to be transferred to the Controller keeps getting larger.Lampros Smyrnaios2023-04-26 15:08:46 +0300
839a797124- Improve performance of full-texts transferring to the Controller, by preloading some bytes for faster response to the Controller's read requests. - Optimize directories-creation process by eliminating the additive check for existence, as that check already takes place inside the "mkdirs()" method. - Remove the obsolete code which in case the specific assignments' subdirectory failed to be created, then a different base-dir was used instead. Since the user-defined baseDir is already been successfully created upon initialization, any problem on creating subdirectories inside that base-directory will most likely persist even when changing the base directory. Additionally, even if the subdirectory with the changed base-directory succeeded, the "FullTextsController.getFullTexts()" method would not use it, resulting in errors. - Code polishing.Lampros Smyrnaios2023-03-08 13:12:17 +0200

81b61b530fDrastically improve performance by applying a pre-processing algorithm for the assignments-list to open some "space" between assignments which have the same domain, which in return, causes the threads to block less during execution. (The threads block, due to the mandatory "politeness-delay" before reconnecting with the same domain, in order to avoid overloading the remote servers.)Lampros Smyrnaios2023-02-24 23:23:37 +0200
84a37bd4b7- Handle the case, where an instance of a urlReport record (having the same id and sourceUrl), may have failed to give a docUrl, due to en error, even if another instance gives the docUrl and the docFile. The absence of that handling could lead to a record-instance, being assigned a "fileLocation" which was actually an error-message (comment), and as a result the real "fileLocation" would have never been reached to be assigned, so the payload would be lost. - Improve exceptions-handling.Lampros Smyrnaios2023-02-21 15:22:49 +0200
