on i64, can't create the symbol vector options

[hb--]

TECO on i64 seems to be sub-optimal, it seems to be at least very slow, or it is simply looping:

TECO on Itanium is an interesting beast. I'm not sure if V8.4 shipped with the latest TECO images. I do know it works with the latest fixes though, as that's how I build it. They can be fetched from here:

http://ftp.endlesssoftware.com.au/teco/teco32_tv_av/

There were a whole bunch of bugs in the AEST/TIE_I64 facilities that stuffed TECO around. I fixed a great number of them and ended up with something that actually runs (and at reasonable speed too).

[hb--]

No luck, here, on a 8.4 I64 system ...

this is with the vms supplied teco

sorting takes so long?

And also annoying when (using mmk and) teco loops/hangs a control+Y and
stop blows the process(es) away :-(

For the moment I give up, because, even if I get this linked Java dumps on me
with

%SYSTEM-F-IMGDMP, dynamic image dump signal at PC=00000000020C7C10, PS=0000001B

Java tells me this is at SQLITE_SHR+50, whatever that means, I have no idea, yet.
It only confirms that Java called the jdbc jni, which called into that shareable image.

[tesneddon]

Hmm, I'll look into that. I'll be putting in some time to get my changes in and hopefully bring it forward a few versions. So, I'll check it out then.

[hb--]

Take your time. The linker is my friend and I know how to create symbol vectors. But to show that this works, I don't need that shareable image at all: I can link sqlite into my jni.

[hb--]

The problem which results in Java writing a process dump is not related to the symbol vector. It looks like there are problems in the sqlite vms mutex code. Analyzing the dump shows the accvio in or close to that mutex code and Java can't handle the exception, so the last chance handler is kicking in. The printed "Problematic frame" still makes no sense to me. I added some printfs to show what is called. But that is only a start: I need a better way to debug the code. And yes, I should report that to HP :-)

Hi @hb--,

Are you able to show the contents of the log file? Does it actually save anywhere?

[hb--]

I re-created another log file, the PC is different, but I don't think it is really different. Java for some reasons mapped the jni at a different location, that's all. I like this:

$ type "^UP^/tmp//hs_err_pid223434.log"
%TYPE-W-SEARCHFAIL, error searching for "^UP^/tmp/hs_err_pid223434.log"
-RMS-E-DNF, directory not found
-SYSTEM-W-NOSUCHFILE, no such file
$ 

but here it is, anyway

$ ty sys$scratch:hs_err_pid223434.log

Oh, here the OS is iVMS! Maybe I should get in contact with Apple.

[hb--]

Got it to work. For some reasons, I enabled SQLITE_DEBUG, which is not a good idea - at least as long as xMutexHeld and xMutexNotheld aren't implemented. The accvio was in mutex\sqlite3_mutex_held, where sqlite3GlobalConfig.mutex.xMutexHeld is called. Unfortunately I don't remember what problem I wanted to debug when I enabled SQLITE_DEBUG. :-(

[tesneddon]

Ahh, there are some callbacks I didn't implement as they were only used for debugging. I'll create a fresh issue to add those in. Even if they are not necessary for day-to-day life, they would be useful in situations like this (rather than creating a red herring :-).

If you;re happy with the solution I can close this off.
