From 05/03/2012 to 06/01/2012
- 12:47 PM Revision 7229 (metacat): do not include releaseCandidate property - does not seem to be used except for debian? packaging which was never fully implemented.
- 12:39 PM Revision 7228 (metacat): use non-snapshot D1 jars in prep for tagging/release. Still RCs
- 10:45 AM Revision 7227 (metacat): script to aid in converting denyFirst rules to allowFirst
- 10:40 AM Revision 7226 (metacat): use kepler account as default
- 10:39 AM Revision 7225 (metacat): use current default tomcat6 deploy directory
- 09:35 AM Revision 7224 (metacat): include test shoulder defaults for KNB, PISCO and LTER
- 09:25 PM Revision 7223 (metacat): Fixed formatting problem in a documentation file.
- 09:04 PM Revision 7222 (metacat): use metacat.properties to specify the default checksum algorithm to use -- this way it will be easy for us to switch to whatever DataONE decrees.
- 06:16 PM Revision 7221 (metacat): put(sm) for every pid we have a SM value for so that all members receive the entry event and can save locally.
- 02:11 PM Revision 7220 (metacat): add section about importing self-signed certificates into the Java keystore (now that we use strict verification on the java client side when calling replication endpoints).
- 02:01 PM Revision 7219 (metacat): a few additional notes about Metacat replication configuration.
- 10:56 AM Revision 7218 (metacat): Throw an exception when NOT allowed, not when allowed =).
- 10:53 AM Revision 7217 (metacat): ignore partition owner -- always attempt to look up form local store if we were unable to get the SM from the shared map.
- 10:13 AM Revision 7216 (metacat): do not check if this CN has a "perfect" copy of the SM identifiers -- we need any CN coming online to contribute the records that they have locally so that in the event that all three CNs have a partial view of things they all eventually share each others' SM entries.
- 10:10 AM Revision 7215 (metacat): Also get the list size, which may throw an NPE.
- 09:53 AM Revision 7214 (metacat): Only add an AccessPolicy to SystemMetadata during generation when the AccessPolicy is not empty. We've had some scenarios where IdentifierManager.getaccessPolicy() is returning an empty policy because of an empty permission list coming from the db. This was causing InvalidSystemMetadata exceptions during MN to MN replication.
- 09:19 AM Revision 7213 (metacat): push SystemMetadata entries from the CN that has them all to the shared map where other nodes may not have all entries. The CN with the complete copy only pushes SM entries that it does not own and that return as null because those are the ones that are missing on the other, non-complete CNs.
- This is different from the previous approach where a stale CN tried to PULL it's missing entries from the shared map....
- 10:00 PM Revision 7212 (metacat): trace level log for looping over EVERY pid in the system.
- 09:47 PM Revision 7211 (metacat): meant to log the guids (source) not the pids (target)
- 08:51 PM Revision 7210 (metacat): trace level log for looping over EVERY pid in the system.
- 08:18 PM Revision 7209 (metacat): logging for each step of shared identifiers loading.
- 08:07 PM Revision 7208 (metacat): remove pause/resume - seemed to make metacat just hang on SM retrieval. Add more logging when returned SM is null -- want to make sure it is becuase the local node "owns" the pid key even though there is no value for it.
- 06:12 PM Revision 7207 (metacat): due to hudson build issue, did not actually end up testing pause/resume -- trying that again
- 05:53 PM Revision 7206 (metacat): pause/resume was not enough. trying shutdown/restart
- 05:02 PM Revision 7205 (metacat): experiment with lifecycle pause/resume. hopefully it prevents our node from taking ownership of any keys before we are sure we have them all.
- 08:29 AM Revision 7204 (metacat): increase logging and add back in the call to saveLocally() in case the SM object has already been loaded into the shared map but before this node came back online.
- 11:21 PM Revision 7203 (metacat): no need to call saveLocally explicitly since loading from the shared store triggers that behavior locally because of the configured listeners.
- use an iterator over the shared identifiers in case this set is constantly changing.
- 10:10 PM Revision 7202 (metacat): make only one DB call to look up local pids - no need to do a pstmt for every single shared pid.
- 09:05 PM Revision 7201 (metacat): on init (start up) launch a synchronization thread that ensures all shared identifier entries have a corresponding local System Metadata entry.
- 04:19 PM Revision 7200 (metacat): use 'allowFirst' for access rules. We have deprecated 'denyFirst' and deny rules in Metacat as of 2.0.0
- 03:02 PM Revision 7199 (metacat): handle https-only server configuration -- must pull resources from https not http for the skins etc.
- 02:53 PM Revision 7198 (metacat): handle https-only server configuration -- must pull resources from https not http for the skins etc.
- 10:31 AM Revision 7197 (metacat): fix NPE (logMetacat object was not initialized) that was occurring during store()
- 09:33 AM Revision 7196 (metacat): stack trace the HZ put exception during CN-CN replication
- 07:37 AM Revision 7195 (metacat): additional debugging statements for CONCURRENT_MAP_PUT error during CN-CN replication.
- 01:25 PM Revision 7194 (metacat): include eml2.0.0beta4 DTD during Metacat build so that we can continue to accept (and validate) beta4 documents.
- This arose when testing Metacat as DataONE Coordinating Node where legacy documents are being housed in the CN.
- 06:20 PM Revision 7192 (metacat): Don't set the replication status to failed for an object when it is called by a public user. Just throw the NotAuthorized exception. This prevents this node from being de-prioritized because of public calls to the method.
- 04:23 PM Revision 7191 (metacat): include revisions table in the initial temp table population.
- use the "first" creator listed in the EML (either org or person).
use other reasonable default values as needed to fu...
- 02:30 PM Revision 7190 (metacat): add columns: publisher and pub_date. include default values for all columns - even data files should have title.
- still a few todos but closer.
- 12:07 PM Revision 7189 (metacat): script to generate DOI registration spreadsheet
- 04:41 PM Revision 7188 (metacat): share the same dbConnection when inserting and then updating SystemMetadata objects in the backing store.
- any errors encountered during the update will rollback the entire transaction and the SM record will not exist, even ...
- 03:28 PM Revision 7187 (metacat): Do not loadAllKeys() for SystemMetadataMap when Metacat first starts up. hzIdentifiers will be populated with a simple SQL statement rather than the serial loading of every single SystemMetadata object. It will remain in synch using the usual entryXXX() methods as before.
- This should save us resources where we were previously attempting to load ALL SystemMetadata into memory on startup.
- 02:22 PM Revision 7186 (metacat): use LRU eviction policy and a small (1000) map size limit to avoid running out of memory because of a large number of system metadata objects
- 02:17 PM Revision 7185 (metacat): Set the default maximum number of database connections back to 200. After discussion, we've decided it will be better to increase the PostgreSQL limit to 300 and keep Metacat's pool size pretty big.
- 09:57 AM Revision 7184 (metacat): include pidFilter handling - only matches the complete pid. Issues a warning in the Metacat logs when pidFilter cannot be applied but allows the call to getLogs() to return as though there was no pidFilter given.
- 09:33 AM Revision 7183 (metacat): use at least one thread on single-processor machines.
- 05:46 PM Revision 7182 (metacat): Change the database.maximumConnections property to 100. PostgreSQL's docs says it can handle "a few hundred", and would need to be increased from the default 100 max_connections. For DataONE optimization, we increase max_connections, however there are more processes making connections other than metacat, so I'll reduce metacat's default share.
- 04:52 PM Bug #5608: Enable all FK constraints in Metacat production [copies]
- I've drafted a script that corrects FK violations and re-applies the original constraints. The xml_index table takes ...
- 04:47 PM Revision 7181 (metacat): script for re-applying missing FK constraints on KNB production DB.
- 03:04 PM Revision 7180 (metacat): include TRACE level debugging for specific classes we want to have performance metrics for.
- 02:31 PM Revision 7179 (metacat): Add a few logging statemnts for round trip replication metrics.
- 02:12 PM Revision 7178 (metacat): add trace statements for measuring time to complete SM generation.
- 11:25 AM Revision 7177 (metacat): new D1 jars:
- prevent NPEs from the object format cache when formatId.value is null. This came up during PISCO testing
- 03:05 PM Revision 7176 (metacat): default replication policy set to 0.
- 12:09 PM Revision 7175 (metacat): instead of generating SM and ORE maps during dataone configuration/MN registration, moved this all to the replication admin screen where we can target generation for specific nodes. That way it's more controlled as to when and where we generate DataONE required content.
- 12:00 PM Revision 7174 (metacat): include all EML versions (had been only eml 2.1 for testing)
- 11:59 AM Revision 7173 (metacat): new d1 jars for: remove exception from method decl - was not matching the interface def and not compiling.
- 05:43 PM Revision 7172 (metacat): Append more information such as user name and group to the validating session response.
- 12:46 PM Revision 7171 (metacat): remove exception from method decl - was not matching the interface def and not compiling.
