readpst -e output filenames aren't deterministic

[martinvonwittich]

When I run readpst -e twice with the same input file:

mkdir readpst.output
mkdir readpst.output2
readpst -e -o readpst.output /root/mail_exchange/Some.User.pst
readpst -e -o readpst.output2 /root/mail_exchange/Some.User.pst

the resulting $ID.eml aren't necessarily in deterministic order. They're still identical e.g. for Inbox/1.eml:

host ~ # grep -i '^Message-ID' readpst.output{,.2}/Some.User/Posteingang/1.eml   
readpst.output/Some.User/Inbox/1.eml:Message-ID: <e26d970c5bd345e1b2818d514fa96624@host>
readpst.output.2/Some.User/Inbox/1.eml:Message-ID: <e26d970c5bd345e1b2818d514fa96624@host>

but not any longer e.g. for Inbox/1000.eml:

host ~ # grep -i '^Message-ID' readpst.output{,.2}/Some.User/Posteingang/1000.eml
readpst.output/Some.User/Inbox/1000.eml:Message-ID: <AM0PR08MB427305D64481B39AE42B116DFB472@AM0PR08MB4273.eurprd08.prod.outlook.com>
readpst.output.2/Some.User/Inbox/1000.eml:Message-ID: <95bb64dd32324624a2dd1a104c4a5452@host>

This seems related to #9, but probably a separate issue.

The readpst version I'm using is:

host ~ # apt-cache policy pst-utils
pst-utils:
  Installiert:           0.6.75-1
  Installationskandidat: 0.6.75-1
  Versionstabelle:
 *** 0.6.75-1 500
        500 http://deb.debian.org/debian bullseye/main amd64 Packages
        100 /var/lib/dpkg/status
host ~ # readpst -V                
ReadPST / LibPST v0.6.75
Little Endian implementation being used.

OK, this is very likely just a duplicate of #7. I noticed that for the different runs, I was getting a different amount of skipped files. While trying to debug that, I found the report #7. After using -j 0 for two runs, I no longer get different Message-IDs:

host ~ # grep -i '^Message-ID' readpst.output{.1,.2}/Some.User/Posteingang/1.eml            
readpst.output.1/Some.User/Posteingang/1.eml:Message-ID: <e26d970c5bd345e1b2818d514fa96624@host>
readpst.output.2/Some.User/Posteingang/1.eml:Message-ID: <e26d970c5bd345e1b2818d514fa96624@host>
host ~ # grep -i '^Message-ID' readpst.output{.1,.2}/Some.User/Posteingang/1000.eml
readpst.output.1/Some.User/Posteingang/1000.eml:Message-ID: <FA075301-28D2-4520-9CC2-C25879EEF41E@host>
readpst.output.2/Some.User/Posteingang/1000.eml:Message-ID: <FA075301-28D2-4520-9CC2-C25879EEF41E@host>
host ~ # grep -i '^Message-ID' readpst.output{.1,.2}/Some.User/Posteingang/8000.eml
readpst.output.1/Some.User/Posteingang/8000.eml:Message-ID: <06f7280727364b7a9740b6ad228dd51a@host>
readpst.output.2/Some.User/Posteingang/8000.eml:Message-ID: <06f7280727364b7a9740b6ad228dd51a@host>

The emails are still different due to randomly generated boundaries, but that is tracked as #9.
