Re: Custom EOQualifier
I agree with Xavier. Try it and see how it goes. You should be able to use the existing qualifier and it will work. Here’s a summary of things to try: 1) QualifierOperatorCaseInsensitiveLike - it should work. 2) Derived attribute - you can do “upper” in a derived attribute and then in java upper case the string and do an “equals” comparison 3) Create custom collation in the DB for that column so that it is case insensitive I ordered them by how easy to implement. First one is the easiest and third one is hardest but could be more performant in a large table. > On Aug 30, 2024, at 10:40 AM, Xavier (WO) via Webobjects-dev > wrote: > > Hi André, > > You shouldn’t need to do anything, your String will be called as a variable, > the EOQualifer will escape the problematic characters for you. > > Xavier > > >> On 30 Aug 2024, at 16:17, André Rothe wrote: >> >> Hi Xavier, >> >> How I can escape the wildcards, with a backslash?

It does; that's where I've found my classpath is definitely OK. Alas, the
bloody Java ignores the classpath and happily loads the JDBC driver from
java.ext.dirs, regardless the classpath path :(

Re: FB JDBC version?
Jesse,
I might be wrong, but I understand this is not the driver version, but a JDBC
compatibility level or something like that. Anyway, the FrontBase driver
version is three-part (like 2.5.10), not just major.minor.
Thanks!

Hi there,
how does one properly determine the current FB JDBC driver version?
Lately we were not sure whether all our installations contain the newest
release, and thus I've added a code to log out the version. The code I've found
— is there another, better, and more reliable variant? — looks like this:
===
def eoa=EOAdaptor.adaptorWithModel(model)
def pin=eoa.plugIn()
logln "using driver $eoa.plugInName ${pin.jdbcInfo['DRIVER_VER']}"
===
The problem is, this code gives me different results (sometimes 2.5.10,
sometimes 2.5.9) for the very same frontbasejdbc.jar (which should really be
2.5.20 — 240643 bytes, md5 72266d135712d26c60bc5cc1e1dc7c94). What do I

Re: FB JDBC version?
I happen to use a different API, perhaps results are different.
java.sql.Driver driver = java.sql.DriverManager.getDriver(“my login string…”);
ERXApplication.log.info("Driver Version: " + driver.getMajorVersion() + "." +
driver.getMinorVersion());

FB JDBC version?
Hi there,
how does one properly determine the current FB JDBC driver version?
Lately we were not sure whether all our installations contain the newest
release, and thus I've added a code to log out the version. The code I've found
— is there another, better, and more reliable variant? — looks like this:
===
def eoa=EOAdaptor.adaptorWithModel(model)
def pin=eoa.plugIn()
logln "using driver $eoa.plugInName ${pin.jdbcInfo['DRIVER_VER']}"
===
The problem is, this code gives me different results (sometimes 2.5.10,
sometimes 2.5.9) for the very same frontbasejdbc.jar (which should really be
2.5.20 — 240643 bytes, md5 72266d135712d26c60bc5cc1e1dc7c94). What do I
overlook?
Thanks,

Re: overlapping R/Rs in same session
If you open a second tab, using cookies, they are shared. If you continue doing more than 30 actions or so in the second tab, and then later try to do 1 action in the first tab, it will break.

Pretty often, e.g., if one opens a link by shift-cmd-click in a new tab, and in other cases too, more tabs/windows simply share the same wosid cookie, i.e., the same session.

Re: overlapping R/Rs in same session
Hi OC, This is a very complex question with many possibles solutions having their owns problems... If you use auto-magic WO with auto generated url using actions bindings with complex pages, there is no safe way to support multiple concurrent tab or windows in the same browser for these components. You would need an infinite page cache to make sure the last used tab is not forgotten before its next interaction. If you can limit the contents allowed in "other" tabs, it is possible to have a safe solution by using only direct actions inside those allowed components and keep the main app in the easy for dev mode. I developed a way to detect other tab usage and bloc them (the last opened deactivate other one). If the user comme back to a previous one, an alert id displayed and it is possible to continue there but you are back to the app home page. This is mostly to help when they close the active tab to keep the active session. All session based server frameworks lock the session during a request to ensure the session data is coherent, this limit the processing to 1 concurrent request per session on the server. You can almost eliminate the pause effect for long requests by using LongResponsePage or other means to display a work in progress in a background thread. You start the long request in background and create an auto refreshed progress page and return it to the browser quickly, If you want to go full concurrent requests for a user, you need to get rid of the session and page cache, this can represent a huge amount of work, it would probably be better to switch to a full page JS frameworks for the UI but even those does not like multiple tabs with complex apps... I try to adjust my UI to reduce the need of those multiple tabs or windows, this is by far the easiest way to help users.

overlapping R/Rs in same session
Hi there, looks like the main cause of those overlapping R/Rs which we ar clashing with lately is that some users just open their session in more windows or tabs, and work concurrently in those. Sigh. It's self-evident why it is a pretty bad idea from the technical POV, but I am afraid we can't explain it to plain users. Worse, if we found a way to prevent that (offhand, I am not sure whether it is technically possible, but even if so), I am afraid the users would complain that they simply insist on this terrible approach. Now though they complain some operations are “inexplicably” slow: “I understand that operation A which I've launched in one of my windows is complicated and thus takes many seconds, that's OK. But at the same moment I've launched an operation B in another of my windows; operation B is trivial and should be lightning fast, but it took an eternity! Fix your broken application!“ Well you twit, op B took an eternity since it first waited many seconds until the slow op A you yourself launched in the same session finished; after that, A took about 100 ms of its own time. But this kind of explanation would not do with plain users at all :( Could anybody see any practical solution? Note please that making _all_ R/R lightning fast is practically impossible (we would have to refactor too heavily, not an option in a near future). Besides I am afraid even if we somehow succeeded to make all R/R reliably belong a second or so, they would still launch ten second-long operations in ten windows plus one 100 ms in another, and then complain that the last one took seconds too :( At this moment about the only solution very ugly work-around I can think of would be to choose a couple of the trivial operations whose speed the users consider most important, and re-write them without session (they would still need to work with the session ID, but important things like the current user etc. would have to be cached in the application in some kind of static map without using the Session instance at all). Sigh. Darn complex, but still worlds easier than attempting to make _all_ R/Rs 100ms-or-less... Any better idea? Thanks and all the best, OC ___ Do not post admin requests to the list.

Re: fetches too often (was: weird locks) in faultWithPrimaryKeyValue
Hi,
Using the same OSC for both the RR-WorkerThreads and long-response background
threads may result in deadlocks in a heavier load scenario (which is bad for
your karma)
Using en extra OSC for every background task may consume too much memory.
Fortunately there exists the combination of ERXFutureTask and ERXTask
Instances. Each ERXTask object will be connected to one OSC of a OSC pool.
The number of simultaneous ERXTask is limited to the size of OSC-pool, but
the background tasks doesn't interfere with RR-Threads.
I was very much inspired by the following screencast:

If you have time sensitive parts distincts from more report like pages with
unpredictable fetch complexity, you may split them in different app or use a

Re: fetches too often (was: weird locks) in faultWithPrimaryKeyValue
Hi,
As Samuel wrote, I do create new OSC when I make large export / report without
any editing.
So, it creates a new dedicated connexion to the database and does not slow down
the users using the shared editing context / main connexion.
ERXObjectStoreCoordinator _tmpObjectStoreCoordinator = new
ERXObjectStoreCoordinator(true);
WOSession _localSession = new WOSession(_tmpObjectStoreCoordinator);
_localSession.defaultEditingContext().setUndoManager(null);
_localSession.defaultEditingContext().lock();
and after the process
_localSession.defaultEditingContext().unlock();
_localSession.defaultEditingContext().dispose();
_localSession.terminate();
_tmpObjectStoreCoordinator.dispose();
Hope it helps,
Jérémy

Now it works all right and reliably, but I observe very strange behaviour: with
the separate OSC, the direct action is, in average, considerably slower; and
the culprit seems are DB roundtrips. I hope I am missing something completely
obvious again...
When I create my local EC for my direct action this way:

there are no roundtrips at all.
I would understand the first fetch in the separate OSC, but subsequently, it
should just use snapshots like the default root store does, should it not? What
am I missing?
Thanks,

When ActionSpecificOSC is off, it never ever locks. When it is on though,
occasionally the “will fetch” log marked // 2 is the very last thing which the

Aside of moving the localec.dispose to finally, which would be safer, but in

possible culprit?
Side question: originally, my // 1 line looked like

an invalid EC with a null rootObjectStore. What the H.?!?

Re: weird locks in faultWithPrimaryKeyValue
Hi OC,
Last week, I spend some time to optimise an app after seeing strange behaviour,
the cpu usage of this app was growing with time with no logical explaination.
Your case sound similar to me so I share my experience on this.
During these high cpu usage period, the app had strange locking and No snapshot
for gid errors I did not understood. At >120% cpu usage, the app was getting
almost unusable. After a restart, everything went back to normal.
After spending some time in console, I noticed that the heap allocation was
growing and after some time, the app began to slow down. The VM was never doing
"old generation" gc probably because the heap was not used enough to trigger
it. After issuing a manual GC call (from console), the memory usage went down
and the cpu usage dropped also.
This problem was triggered by the addition of sensor logging in the system,
about 175k entries each day saved in the database by a rest controller action.
I suspect there is some weak reference usage inside EOF (probably for
snapshots) that remains until the more aggressive GC do it's job.
I solves my problem (at least it seems to works) with a periodic call to the
commands by scheduling a task every hour :
Runtime.getRuntime().gc();
Runtime.getRuntime().runFinalization();
I do not know if the second is required but it does not hurt.
Hope this can help someone,
Samuel

weird locks in faultWithPrimaryKeyValue
Hi there,
I've got a direct action, which sometimes needs to get an object with a known
PK, for which I use faultWithPrimaryKeyValue. Works well for years, but lately
the fetches went longer, so I decided to allow it to use a separate OSC not to
clash with the normal database requests.
The result is weird:
- sometimes, faultWithPrimaryKeyValue in the dedicated OSC is lightning fast,
as presumed
- sometimes though, it never ends?!? :-O
It does not lock once and then stay locked, the cases are intermittent. Also,
it never locks when I test myself at my development machine; happens on the
deployment site only, sigh. I have also reasons to believe that the DA does not
deadlock with another thread (essentially since at the moment of the first
lock, nothing at all ran in parallel).
The code looks like this:
===
static sharedosc
WOActionResults someAction() {
try {
boolean oscpolicy=ERXProperties.booleanForKey('ActionSpecificOSC')
def localec, osc
... ...
for (... a couple of times ...) {
...
if (some-condition-which-says-I-need-to-fetch) {
if (!localec) {

When ActionSpecificOSC is off, it never ever locks. When it is on though,
occasionally the “will fetch” log marked // 2 is the very last thing which the
appropriate worker thread ever does. In other (intermittent) cases it all works
well.
Aside of moving the localec.dispose to finally, which would be safer, but in
this case irrelevant for no exception ever happens, can you perhaps see a
possible culprit?
Side question: originally, my // 1 line looked like
(localec=ERXEC.newEditingContext(osc)).lock(). Far as I can say, should work
precisely same way as the above, but did not: when the osc was null, I've got
an invalid EC with a null rootObjectStore. What the H.?!?
Thanks and all the best,
OC

Re: Solved: awake-time long lags

I forgot to mention that at the very same time when _some_ R/Rs sport the terrible tens- or even hundreds-second lag, most _other_ ones run concurrently with that and work quite normally (their component-level logged-out awake comes just a couple of millis after the app-level one). Far as I understand Java, it suspends all threads while GCing, so all R/Rs would be affected the same way, would they not? Besides we happen to log the memory state, too, and most time (especially when the worst lag happened) we are well below 20 % of the max available Java memory (-Xmx), which itself is well below the physical RAM. Far as I can say, there was no other memory-consuming task at the same moment (but for FrontBase, I understand there's essentially nothing other of importance running on that machine than the WO app).

awake-time long lags
Hi there, we are encountering another weird problem: a (very) long lag awake-time. We happen to log the application-level awake and some of the component-level awakes. Normally, the latter happen just a couple milliseconds from the former.

Solved: Properties file not loading
NSProjectBundleEnabled is critical! I don’t rightly know what this setting is about. By the name of it, I’d figure if it was on and enabled it would make a bundle for ProjectBuilder and/or Xcode (back when Apple had not abandoned us). For an app to find properties in a framework the "WO" tab in a launch configuration must have: checked -DNSProjectBundleEnabled=true It’s the key difference between the new launch config and the old one that made it work. Also, if you happened to follow closely, I mentioned that one app I had was fine and the other wasn’t. The app that was fine (could see properties in the included framework) is a newer app and the launch config for it had NSProjectBundleEnabled both checked and true. The older app, did not. > On Jul 31, 2024, at 10:45 AM, Aaron Rosenzweig wrote: > > Thanks Ramsey, > > That’s a very insightful tip. My framework had it correct but both apps did > not.

Re: Properties file not loading
Thanks Ramsey, That’s a very insightful tip. My framework had it correct but both apps did not. Namely, inside the tags of the pom.xml file should contain: Resources false Components Resources false Resources WebServerResources false WebServerResources But that didn’t help my situation of one app being the framework properties and the other app not seeing them. Still, it makes sense to have that defined in both the apps and the framework so glad you called it out! Thank you. Good news though, I’ve made some progress. If I make a completely new Eclipse launch config (not a duplicate) I can launch the troublesome app and the framework properties are visible to the app! Curiously, I don’t know what is significantly different between the new and the old “.launch” config files. When I try to selectively make changes by hand to the old file (while visually diffing with the new file) the result doesn’t work. If copy/replace all the contents of the old with new, it works. The old .launch file is in git and shared by others. So right now I’m trying to get things like VM arguments and other settings into it while keeping it still finding the framework properties.

Re: Advisory: Eclipse bundless builds + maven = no está bien
I wasn't online yesterday, so maybe I'm too late to help here, but... I have a maven archetype (project template) for a webobjects application posted here, https://github.com/nullterminated/woarchetypes (I actually planned to make one for d2w and frameworks too, but I haven't gotten around to it) Anyway, the generated project does not require a WO installation at all. It just finds all the jars needed in your maven repo. It doesn't require you edit maven settings.xml at all. It lists the wocommunity things in the pom.xml so it can find those. You just create a project with it, and it works. It even has a profile where you can build a woapp in a docker container and push the image to AWS ECR if you're into that sort of thing. The only fiddly bits with that are 1) you need docker set up so you can use it without sudo, and 2) you have aws-cli installed and set up so you can push the image to ecr when given the commented properties in the pom.xml file. https://github.com/nullterminated/woarchetypes/blob/master/webobjects-app/src/main/resources/archetype-resources/pom.xml I should probably update it to Java 21 too, it's still on 17. It's based on that wodocker thing I was telling you about a while ago. It has ECR now and I fixed the ENTRYPOINT in the dockerfile so the woapp can run shutdown hooks properly when the container is killed.

Summary: modern maven requires secure HTTPS
I haven’t figured out all my ant -> maven conversion issues but wanted to summarize one finding. Newer maven installations require HTTPS (with an “S” for “secure”) for your connections to things such as the wocommunity repos. It wasn’t always this way and following community tutorials you might cut and paste and not realize the difference between http: and https: You might see lines like this when working with maven: Using mirror maven-default-http-blocker (http://0.0.0.0/) for wocommunity.releases (http://maven.wocommunity.org/content/groups/public). That’s because there is a default settings file in a location like this one if you are using home-brew: /usr/local/Cellar/maven/3.9.5/libexec/conf/settings.xml And the following definition there ruins your day: maven-default-http-blocker external:http:* Pseudo repository to mirror external repositories initially using HTTP. http://0.0.0.0/ true The good news is the fix is simple, be sure you always use “https:” (with the “s” on the end) whenever you need a resource. Inside your local ~/.m2/settings.xml you probably need something like this: https://maven.apache.org/POM/4.0.0"; xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="https://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd";> org.objectstyle.woproject.maven2 default true wocommunity.releases WOCommunity Releases Repository https://maven.wocommunity.org/content/groups/public true false wocommunity.snapshots WOCommunity Snapshots Repository https://maven.wocommunity.org/content/groups/public-snapshots false true wocommunity.releases WOCommunity Releases Repository https://maven.wocommunity.org/content/groups/public true false wocommunity.snapshots WOCommunity Snapshots Repository https://maven.wocommunity.org/content/groups/public-snapshots false true ___ Do not post admin requests to the list.

Re: Maven build - no main bundle name
Hi Markus, I'm still getting a similar error when I do "mvn build" from terminal -> [ERROR] Unresolveable build extension: Plugin org.wocommunity:wolifecycle-maven-plugin:2.6-SNAPSHOT or one of its dependencies could not be resolved I'm referring to the 2.6-SNAPSHOT from the pom.xml file like so: org.wocommunity wolifecycle-maven-plugin 2.6-SNAPSHOT true true Not sure what I'm missing, maybe the group id is wrong?

Re: Maven build - no main bundle name
you should use version 2.6-SNAPSHOT for wolifecycle-maven-plugin, which is the current one and do you refer to the wocommunity repository for obtaining the plugin?

Hi Markus thanks for the quick reply! Good question, I don’t know. I haven’t run from command line, hadn’t done it with Ant and also haven’t tried it with Maven.

Maven build - no main bundle name
Hi, I’m trying to convert an ANT based webobjects application into a Maven build. At the moment It’s building in Eclipse without errors but when I try to launch within the Eclipse environment I get errors due to not finding the main bundle. Specifically the following call inside of ERXApplication returns null: NSProperties._mainBundleName() It should return something, but it doesn’t. Has anyone any advice on what the issue might be?

Re: FrontBase speed, feels weird.
Hi OC, Your problem description smell like an IO contention. BTW, this is not FB exclusive, all database will have the same kind of behaviour. If the is no index for the where condition, you force a table scan (read all the table rows to validate the condition). If the row data in memory, this is fast, if it need to be read from disk, speed can vary a lot depending on the precise amount of data in cache and disk usage art this moment. The size of your row data can also create an amplification of this problem (few int VS many timestamps and char columns for example or if you fetch large blob). If you are on very fast PCIe SSD, it is usually very fast but regular HDs have a very limited IO capacity.

FrontBase speed, feels weird.
Hi there, for years and years, we happily use FrontBase. Lately though we are bumping into somewhat weird behaviour: we observe inexplicably long fetches, even with tables which are not extremely big, no joins, trivial conditions. What's even more intriguing is that in sql92, it was much faster. Even so, the problem was at the FB (not application) side, for an index did help tremendously. Does not make really sense to me, and I wonder whether there might be some weird problem in the FB itself, which might raise its head soon and bite us hard. - the table contains about 16 000 rows, that's not too many; - the fetch condition is trivial, just WHERE SOME_BOOLEAN_COLUMN = false; - the number of found rows is only 13 currently (and never exceeded 100). These fetches took seconds — usually about 1200 ms, not once below 1000, occasionally almost 3000 ms. When I've tried the very same fetch in sql92, it was instantaneous, which feels pretty weird too and lead me to a suspicion that the problem is at the application side. Nevertheless it was not: I just have added an index for the column, and the fetches are ways quicker now (usually below 30 ms). What intrigues me and the reason I write this mail, it does not seem to me reasonable that a plain fetch from a table of ~16K rows which yields (considerably) less than 100 result rows, without any join and with a completely trivial condition, could (without an index) take that long. Does it make any sense to you, who understand SQL/FB better than me? Is that normal? There are other fetches from the same table, with considerably more complex conditions, taking at worst a couple tenths of second; that seems normal to me.

Re: WOAjaxCollapsibleComponentContent ???
I agree about the examples - But . . . some are so nondescript that even
finding out what issue they try to cover is more or less impossible unless you
already know what you are looking for. It is so fascinating and powerful what
is available in Wonder and at the same time so frustrating realizing that
something might be there, finding it and making sense of things.
Time to write a successor to Learning The Wonders. Oh wait, was is “time” ? Is
that what I am constantly short of 😇?

Hi Markus :-)
Glad that worked out for you. I think there is an AjaxExamples project in
WOnder which is an app you can run and see a few things.
You pick up on things after toiling with it for a while.

Re: WOAjaxCollapsibleComponentContent ???
Hi Markus, To use like you envision you need to add some scaffolding. Realize that the ajax link and the ajax submit button can be given a named function. When you do that, they don’t render, put provide a name you can call on the client side that will do a round trip to the server. So you need to consider if you have a form (or not) and if you want to synchronize bindings (or not) to choose between them. But let’s assume you just want a “click” without form values going across.

Amazon Linux 2023
Hello, I am deployed to Amazon Linux 2 and need to move to Amazon Linux 2023 by March 2025. Was anyone else in this boat / has already done this migration? If so, is there anything I should be aware of before I start, or smooth sailing? I have a very manual deployment, but have extensive notes from moving between AL1 and AL2 so hoping that should help.

Re: [POSSIBLY SOLVED]: Cannot obtain globalId for an object which is registered in an other than the databaseContext's active editingContext
Just a quick followup: I've tested further, and alas, looks like the very same problem may happen regardless the fetchTimestamp due to inverse flattened M:N relationships. Test case same as below, just without 1/4, but with a flattened M:N two-side relationship; culprit in (vii) very slightly different — the original relationship gets filled from the snapshot without any problem, but the inverse may (quite probably) need to be fetched, with precisely the same outcome.

[POSSIBLY SOLVED]: Cannot obtain globalId for an object which is registered in an other than the databaseContext's active editingContext
Hi there again, I was eventually able to repeat the problem and it sort of stinks by a bug in EOF (or I am doing something wrong, of course, as so often :)) My test code is just a wee bit at the convoluted side, based on my own model and besides written in Groovy, thus there's no point in quoting it; but the gist is this: 1. create an EC1, assign it a fetchTimestamp in future (something like System.currentTimeMillis()+1500 should suffice) 2. lock EC1 3. fetch into EC1 an object with a :N relationship and change that relationship, not saving the changes 4. wait until the fetchTimestamp expires 5. in a separate thread with its own EC2 (locked) change the same relationship of the same object (localInstanceIn(EC2) of course) 6. save the changes in EC2 7. back in the original thread, wait until the thread with steps 5 and 6 ends. Then unlock EC1 8. finally, in an unrelated EC3 insert some unrelated new object and saveChanges... ... and at least at my side, I get “Cannot obtain globalId for an object which is registered in an other than the databaseContext's active editingContext“ exception all right! I believe the steps above are completely valid and should not cause problems, or do I overlook something here? I might be wrong, it is a bit at the complex side, but I think this is what happens under the hood: (i) EC3 saveChanges of step 8 just calls EOObjectStoreCoordinator.saveChangesInEditingContext ... (ii) which first makes sure there's a proper source (happens to be EODatabaseContext) for each inserted object in its _sources; this EODatabaseContext happens to be the only shared EODatabaseContext a simple application like this one uses (no more OSCs, no concurrent DB access) (iii) each _source gets _willPrepareForSave and then each _source gets prepareForSaveWithCoordinator — and this sets its _editingContext to EC3! (iv) furthermore each _source gets recordChangesInEditingContext, performChanges, and eventually commitChanges (v) inside of commitChanges, EODatabaseContext finds that some changes really happened and posts EOGlobalIDChangedNotification (vi) EC1, which up to this moment was dormant, observes this notification and through _globalIDChanged, _sendOrEnqueueNotification, yadda yadda, eventually gets to merge the change into its own object (vii) which change includes checking the current relationship value. Since the fetchTimestamp is already in the past, this involves re-fetching the relationship in EC1 ... (viii) ... which goes through the one and only shared EODatabaseContext we have. That EODatabaseContext though still has its _editingContext set to EC3 from the step (iii))! Hilarity ensues, the “Cannot obtain globalId for an object which is registered in an other...” exception gets thrown (if this did not happen, the EODatabaseContext's _editingContext would get nulled at the very end of commitChanges, too late for us). Do I overlook something of importance? Seems me not to; I guess anyone can repeat the test code 1-8 outlined above (just beware logs — they might fire the fault prematurely; also I've found essentially each localInstanceIn locks ECs and thus disrupts the normal processing — best to prepare all the ECs and all their local instances at the very start, around the step 1). What would be the best fix/work-around? I can't see any simple one; and I would rather not override and re-implement the complete and rather non-trivial commitChanges method.

Memory Adaptor
Hi, I try to use the Memory adaptor for an EOModel. But on ec.saveChanges() I get an exception because the EREntityStore (er.memoryadaptor.ERMemoryEntityStore) cannot be instantiated within the EREntityStoreFactory. How can I solve that problem? I have created the EOModel with "Memory" as adaptor, then I lock my EC and create some EOs and execute ec.saveChanges(). Should I configure more things?

I'm talking only about ERPersistentSessionStorage.framework, and runtime
failures occur whenever it hits something in the object graph rooted at your
Session that isn't Java-serializable for any reason (including EOs, components,
objects from Wonder, objects from your codebase). The most recent thread on
this seems to be "WOSession serialisation redux" started by me on 19 May 2015.
Ramsey thought at the time that he'd made Wonder-side fixes to bring it all
"about 95% there". Of course, there's now 9 years of additional commits and
bit-rot, but maybe it's still around that mark. Then there's your code,
everything in your Sessions, EOs, and components. You can always give it a try
and see what happens, but if you're only "about 95% there", that's a lot of
unrecoverable, runtime failures to store your sessions.
I wasn't talking about anything you're doing below.

Hmmm... can you recall please some scenarios, which lead to the spectacular
failure?
Based on the ER source code and some Ramsey suggestionst (thanks again!) I've
found a way which so far, tested just for a short time only at my side, seems
to work reasonably well — here's the gist, without error checking, logging and
other cosmetics:
===
class OCSSession extends ERXSession {
WOContext lastContext
void sleep {
if (context.page) lastContext=context.clone()
super.sleep()
}
}
class OCSDirectAction extends ERXDirectAction {
WOActionResults restorePreviousStateAction {
Session ss=session()
if (ss.lastContext) { // code essentially stolen from ERD2WDirectAction
String cid=ss.lastContext.request.stringFormValueForKey('__cid')
if (cid) return ss.restorePageForContextID(cid)
if (ss.lastContext.page) return ss.lastContext.page
}
pageWithName(MainPage.class.name)
}
}
===
If you can foresee case(s) when it would fail, I'd be grateful for some hints,
so that I test them here and update my code appropriately.
Thanks again and all the best,
OC

Re: re/store context somehow? (OCsite)
Your best bet is likely to store the entire WOComponent as an ivar in the session. You can get it from context().page() That way wen they return and the session is still alive you can return that ivar to render where they were and what they were doing. So you’ll need to store it in the session in something like the end of appendToResponse() and then maybe have a link in the top left corner to “restore prior page" > On May 17, 2024, at 4:56 PM, Amedeo Mantica via Webobjects-dev > wrote: > > I no longer use WO but I recall this framework in wonder: > ERPersistentSessionStorage > > Amedeo > > >> On 17 May 2024, at 22:01, Martino Limido via Webobjects-dev >> mailto:webobjects-dev@lists.apple.com>> >> wrote: >> >> Hi there, >> >> it’s important to note that the `WOContext` object in WebObjects ends with >> the lifecycle of the request and response.

Re: re/store context somehow? (OCsite)
Hi there, it’s important to note that the `WOContext` object in WebObjects ends with the lifecycle of the request and response. This means that simply storing the `WOContext` object is not feasible as it will no longer be available after the request is completed. ### Possibility of Implementation: 1. **Context Serialization**: - While WebObjects does not natively support serializing the entire `WOContext`, it is possible to manually serialize the essential parts of the context. This includes capturing the state of components, user inputs, and any relevant session information. - You can use `context().clone()` in `Session.sleep()` to clone the context state. However, ensure that all referenced objects within the context are serializable. This might involve customizing the serialization process for complex objects. 2. **State Storage**: - Store the serialized state in a persistent format, such as a database or a session file. The storage mechanism should be robust enough to handle the complexity of the serialized data and ensure it can be accurately retrieved later. 3. **State Restoration**: - In the `restorePreviousAction` DirectAction, implement a mechanism to deserialize and reintegrate the previously saved state. This involves reconstructing the `WOContext` and ensuring all components and user states are accurately restored. - This might require a custom deserialization logic to handle complex objects and ensure they are correctly linked within the session. ### Challenges: - **Complexity**: Serializing complex objects and managing cross-references can significantly increase code complexity. WebObjects' inherent statefulness and deep object graph make this particularly challenging. - **Data Integrity**: Ensuring data consistency during the serialization and deserialization process is critical. Any mismatch can lead to errors or inconsistent application states. - **Performance**: Serialization and deserialization can impact performance, especially if the context is large or complex. It’s important to optimize this process to minimize the performance overhead. ### Recommendation: Given the complexities and potential issues with this approach, it might be better to rethink the application design. Consider structuring the application to use DirectActions with simpler states that are easier to restore. This could involve: - Breaking down complex states into smaller, more manageable parts that can be easily serialized and deserialized. - Ensuring that each DirectAction has a well-defined and minimal state that can be captured and restored without requiring the entire context. - Leveraging stateless designs where possible, and using session storage judiciously to maintain essential state information. ### Conclusion: Implementing this functionality is technically possible but requires significant effort and a deep understanding of the object lifecycle in WebObjects. Given that the `WOContext` object ends with the request/response cycle, manually serializing and restoring its state is complex and potentially error-prone.

re/store context somehow?
Hi there, my client made a somewhat weird request: wants me to store “the last context the user worked in” in his session, and restore it when the user comes to the application through a specific Direct Action (and the session still lives). In other words, suppose the user works in the app for awhile, and then closes his browser, remembering just the session ID, nothing else. Next thing he does, he opens .../OurApp.woa/wa/restorePrevious?wosid=prevSessionID — and wow, he finds the browser window in precisely the same state it was when he closed the browser some time ago. (Far as possible of course, let's assume for simplicity the internal app/session/DB state did not change meantime.) I guess most probably I need to save context().clone() into session each time in Session.sleep(), that's not difficult. But then in my DirectAction.restorePreviousAction I need to resurrect the saved context somehow, but I can't find a way to do that. Does anybody know how to? Thanks!

webserverresources path for older versions
Hi there, on our testing site, we often install more applications served by different builds, so that testers can easily compare the changes. E.g., two applications “Test2” and “Test3” are configured in JavaMonitor with paths “/Local/WOApps/Test/build2/Test.woa/Test” and “/Local/WOApps/Test/build3/Test.woa/Test” (and different log paths, yadda yadda). Works like a charm... but for the web server resources; they are, of course, by default shared and all builds automatically use the latest installed copy. It would help if we could somehow force an application (the one based on an older build) to consistently provide resources from the application folder, effectively ignoring split install, like it happens with direct connect, generating URLs like “/cgi-bin/WebObjects/Test.woa/wr/wodata=/the-current-app-path/Test.woa/Contents/WebServerResources/SomeFile.css” instead of those standard split-install “/WebObjects/Test.woa/Contents/WebServerResources/SomeFile.css” ones. Is there a setting or another trick to enforce that? I've tried to set “-WODirectConnectEnabled YES” for an application served by an older build, but to no avail, it still keeps generating the normal split-install URLs. Or is there another easy trick to do that? Of course I could use the “href” binding in my “ERXStyleSheet” and similar tags instead of “filename” (and tweak all the “additionalCSSFiles” in a similar way, yadda...) and compute the paths programmatically based on something like “WOApplication.application().path()”, but that could get sorta ugly soon... and besides, I'd much rather exploit the framework power than to skip it and DIY :) Thanks!

It seems to be complaining about the "org.maven.ide.eclipse.maven2Nature", so just click "Cancel" and you should be fine. That project nature is deprecated and is in there only for WO, so it won't matter to you or Eclipse.

Re: Wonder-slim
Hi Ricardo, https://github.com/undur/wonder-slim in short, it's a fork of Wonder that removes everything except ERExtensions, WOOGNL and JavaWOExtensions (which are all combined in a single framework, since they're usually all required and present in WO projects) plus Ajax.framework. So basically, a small subset of Project Wonder. It also: * Has >a lot< of stuff removed, reorganized, refactored and cleaned up to make it cleaner, nicer and easier to understand and maintain * Based on JDK 21 * Has all logging moved to slf4j-api and log4j specific stuff moved to a separate framework (which replaces log4j with reload4j). * Replaces proprietary APIs and library usage with the standard methods we've gained from modern JDKs (so the only 3rd party dependency it pulls in is slf4j-api) * Assumes it's running on the last released version of WO (5.4.3), removing workarounds for older versions * And a lot more… That's just off the top of my head I initially started it mostly as an experiment to learn Wonder's insides, see how it could be cleaned up, better organized and even split up, planning to eventually backport some of the cleanup work. But eventually it just got out of hand and I now just use it in all of my projects :). A point to keep in mind is that it also removes everything related to EOF, since in my world EOF is legacy (and yes, please don't be insulted, I'm well aware that that's a subjective view from a Cayenne user. For actual EOF users I know EOF is fine and in full use). But that means — if you're currently using Wonder/EOF in your projects, I would not recommend Slim since you're probably dependent on both Wonder's APIs, patches and fixes to EOF. A side project was splitting off the deployment tools into a separate project (where I haven't done as much work yet, but that's soon to come). Just feels like these tools deserve their own effort. https://github.com/undur/wonder-deployment All in all, this is really something of a niche project and I wouldn't consider it essential for anyone currently using Wonder. But for someone like me, who uses WO only for it's web framework features, and just wants some of the basics and fixes Wonder adds in that area, it's turned out nice.

Re: Debug frameworks with maven project
So, a little late addendum to this discussion... While posting a video on YouTube yesterday I noticed a video I created last year (and had totally forgotten about) that illustrates this exact issue: https://www.youtube.com/watch?v=c2-YxVDYu_8 In short, the reason I'm not having problems with linking between projects is that for a long time I've been running my WO applications as plain java applications, not as WOApplications. The reason I did this initially is that WOApplication launch configurations generate a totally botched class path for maven projects, as described here: https://github.com/wocommunity/wolips/issues/153. So, yeah... If you're using maven and want a correct classpath and proper inter-project relationships, run your applications as Java applications, not WOApplications.

Re: action in a sub-component?
Hugi,
thanks, works like a charm!
(So far I bumped into no problem without setCurrentComponent( parent() ).
Somewhat weird, but well, far as it works... :))

Re: action in a sub-component?
I've never done this, but it's such a nice brain-teaser I had to try :). And
what I did _seems_ to work.
https://gist.github.com/hugithordarson/37d03336de17cfcf3ac399f6325e0ff2
The key is making the child component non-synchronizing, otherwise the parent
action will get invoked during the pulling of binding values. And it should be
quite OK if the action method returns null, that just means the same as
returning null from any action invocation, i.e. "I'm working within and
returning the current page instance".
I'm thinking… It kind of feels like one would have to setCurrentComponent(
parent() ) in the child before performing the action invocation and then reset
it back to itself afterwards (since we're really invoking an action within the
context of the parent component), but I might be wrong, this seems to work
without it.

action in a sub-component?
Hi there,
I've got a sub-component which uses performParentAction; the appropriate
binding is something like . Works
perfectly.
Purely for aesthetic reasons (and, well, for consistency), I would prefer if I
could use the sub-component precisely same way one uses wo:hyperlink, i.e.,
like this:
Is there a trick to achieve that? Looks like in this case when I try
valueForBinding('action'), I get NULL :(

Re: enumerating sessions?
Hi,
As Hugi wrote, you can access the list via the session store.
Be careful with access to objects inside those sessions, especially EOs since
you are outside their normal RR loop request.
I have a standard way to list active users and keep track of last access inside
session by adding those attributes:
private long lastSleepDate;
private long lastUserRequestDate;
private boolean isRequestFromUser;
and adding those overrides...
@Override
public void awake() {
super.awake();
isRequestFromUser = true;
}
@Override
public void sleep() {
lastSleepDate = System.currentTimeMillis();
if (isRequestFromUser) {
lastUserRequestDate = lastSleepDate;
}
super.sleep();
}
public void setRequestIsPing() {
isRequestFromUser = false;
}
The setRequestIsPing is to discriminate auto refresh ping request in my page
wrapper use to keep session alive when the app is displayed. I have this in the
template:
And this in the component java class:
public String pingString() {
if (ERXApplication.isAjaxRequest(context().request())) {
session().setRequestIsPing();
}
return null;
}
And this to list active sessions (SessionInfo is POJO):
WOServerSessionStore sessionStore = (WOServerSessionStore)
WOApplication.application().sessionStore();
@SuppressWarnings("unchecked")
NSArray sessions =
sessionStore._sessions().allValues();
NSMutableArray sessionInfos = new
NSMutableArray<>();
for (Session session : sessions) {
SessionInfo info = new SessionInfo();
info.hashCode = session.hashCode();
info.lastSleepDatetime = session.lastSleepDatetime();
info.lastUserRequestDate =
session.lastUserRequestDate();
info.timeOut = session.timeOutMillis();
info.usager = session.userAccessService().currentUser();
sessionInfos.add(info);
}
new
ERXKey("lastUserRequestDate").desc().sort(sessionInfos);
Regards,
Samuel

Re: enumerating sessions?
Hi, if you're using WO's standard session store (WOServerSessionStore) you should be able to access the active sessions using: ((WOServerSessionStore)WOApplication.application().sessionStore())._sessions() It will return a dictionary consisting of sessionID -> Session. Not using it though, I'm achieving this myself by using the notifications posted by session management (SessionDidRestoreNotification, SessionDidCreateNotification and SessionDidTimeOutNotification), so I can keep track of more info (like when the session was last touched).

Re: enumerating sessions?
Off the top of my head? I’d not use sessions for that — I’ve done some bank apps where only one session is allowed and some other stuff, but we avoided relying on or tracking sessions, rather we build a login scheme that tracked this concept specifically and we let session and cookies stuff be.

enumerating sessions?
Hi there, is there a way to enumerate sessions which are alive inside of a WO/ERXApplication? I guess I can create such a list myself, adding new ones in session.awake, keeping it weak not to prevent old sessions to be destroyed (or perhaps storing just session IDs), yadda yadda, but it would be much easier and less error-prone just to use a WO/nder service, if there's one. The purpose is that we need to allow an app administrator to list all the normal users which are currently logged in, and be able to force-logout selected ones. Thanks!
