EXODUS Knowledge

EXODUS Intro

EXODUS is the new version of NEOSYS. The entire NEOSYS environment has been converted to Linux, C++ and postgres.

1. EXODUS is comprised of two main sections:

• EXODUS is a complete conversion of the AREV CRUD and web service framework. (https://github.com/exodusdb/exodusdb)
• EXODUS NEOSYS is the complete conversion of the NEOSYS Agency AREV programs. (not public git)

Dictionaries

Unlike object code, each pgsql database has its own set of dictionary files/items.

Processes

The TEST process for all database use the same object code stored in /root/lib, whereas all LIVE process use the object code in /root/neo/.

Debugging NEOSYS EXODUS in C++ gdb

Screen 6: scripts Two scripts can be used to start a process in debug mode. (WARNING: other running TEST or LIVE processes for client will stop during debugging)

• ./test will use the TEST program object code.
• ./run will use the LIVE object code.

Converting AREV to Exodus

Convert Programs

In AREV:

1. Update program source code and check it can be compiled.
2. Ensure the program you want to recompile into exodus has below e.g "*c job" in source code on line 2, col 1
3. Command: "attach adecomc" #attaches exodus recompiler/decompiler
4. Command: "adecom <programname>"

In Cygwin:

1. Run "cygdrive/d/exodus/pickos/syncup.sh" #syncs all decompiled programs to nl19:/backups/current/hosts/win3/pickos/

In Exodus:
Command explanations:

1. rsync arev decompiled code from sshfs /backups/current/win3/pickos/

getpickos

1. There are three "getpickos" & "compall".

TODO down

• cd exodus/service/src getpickos && compall
• cd ~/neosys/src && getpickos && compall
• cd ~/neosys/src && getpickos && compile <progname> or

• WARNING following command is DANGEROUS! all LIVE object code updated and all LIVE/TEXT process restarted!
  • INCLUDES: "exodus compall" and "neosys compall" and "copyall" and "restart all"!
    • Use with caution: "cd ~/neosys && compall"

cd exodus/service copyall TODO up

Convert dictionary items

Two methods: a) Quick exodus patch (next sync-up from overwrite with win10a version) b) Update exodus from AREV

Quick Method

1. Update dict item in win10a
2. In exodus run command "e dicta2e"
3. Paste below and edit for your case:

#include <exodus/program.h>
programinit()

function main() {
    var originalvalue;

    //edit the string
    var replacevalue="Line Description";

    //check the value of the field TO replace
    //SYNTAX: readv(<record/field> from <filename>, <key> [,field])
    readv(originalvalue from "DICT_JOB_INVOICES", "LINE_TEXT", 3);
    outputl("REPLACE:"^quote(originalvalue)^" with "^quote(replacevalue));

    //uncomment below 2 lines AFTER using check above
    //writev(replacevalue from "DICT_JOB_INVOICES", "LINE_TEXT", 3);
    outputl("REPLACED:"^quote(originalvalue)^" with "^quote(replacevalue));
    return 0;
}

programexit()

1. Save, exit and make sure complied.
2. ./doall TEST all bash dicta2e
3. Check changes on a TEST database.
4. ./doall LIVE all bash dicta2e

Safe Method

In AREV:

1. Update dict item in win10a
2. attach adecomc
3. adecom <dictfile> (e.g adecom dict.production.invoices)
4. base2sql

In Cygwin:

1. /d/exodus/pickos/syncup.sh

In Exodus:

1. neosys/src/getpickos
2. doall all import_db R (DON'T USE U!) - unable to import if database exists!
3. TEST database:
   1. Renew dict items in a test database:

• doall all/xxx create_testdb
• doall all/xxx backup_db

1. 1. Check dictionary item in the <dictfile>.cpp file.
