Server Crashing Lock Issue (bug)

HCL Domino Domino Forum
1

Just fyi, what I’d call a bug and other might call a feature (can be avoided by proper coding)…

If you mistakenly pass an uninitialized array to document.lock(mylockarray), it will crash the server (7.0.3, win2k, don’t know about others)

no-fail server crashing code:

set db=session.currentdatabase

dim mylocklist()

'forget to initalize this array…

set doc=db.getdocbyUNID(anyvalidunid)

call doc.lock(mylocklist)

call doc.save(false,false)

doc.unlock
