I don't use one continious vim session and don't load any sessions at
vim startup (the `just the same error' meant that I used an autocommand
in a similar way and got the same error, not that I used the same code).
Instead I create a new session file almost each time when vim exits
and load one of created sessions at vim startup:
1. due to virtual desktops I almost never close any of my projects' windows,
2. I use vim to quickly edit something from command-line, loading any sessions
will discard the most significant part of vim invocation arguments
for this use-case.
Saving session at vim exit is for the case when I have to reload vim
(mostly plugin or kernel updates).
Here is my code:
"▶2 mksession
if has('mksession')
function s:InitSes()
let sesdir=expand('~/.vimsessions')
if !isdirectory(sesdir)
call mkdir(expand(sesdir), "", 0700)
endif
let sesfile=os#JoinPath(sesdir, '.sessions.lst')
let sessions=[]
if filereadable(sesfile)
let sessions+=readfile(sesfile, 'b')
while !empty(sessions) && empty(sessions[-1])
call remove(sessions, -1)
endwhile
endif
let sessplitted=map(copy(sessions),
\'split(v:val, ''\v%(\\@<!%(\\\\)*)@<=,'')')
let sesdirs=map(copy(sessplitted),
'((empty(v:val))?(""):(v:val[0]))')
let sesfiles=map(copy(sessplitted),
'((empty(v:val))?([]):(v:val[1:]))')
execute "cd ".fnameescape(resolve(fnamemodify('.', ':p')))
let curdir=escape(fnamemodify('.', ':p'), ',\')
return [sesdir, sesfile, sessions, sesdirs, sesfiles, curdir]
endfunction
let s:_functions['s:InitSes']=function('s:InitSes')
function s:MakeSession()
let [sesdir, sesfile, sessions, sesdirs, sesfiles,
curdir]=s:InitSes()
let files=sort(map(filter(map(filter(range(1, bufnr('$')),
\ 'getbufvar(v:val,
"&bt")!=#"help"'),
\ 'bufname(v:val)'),
\ 'filereadable(v:val)'),
\ 'escape(fnamemodify(resolve(fnamemodify(v:val,
":p")),
":~:."), ",\\")'))
if empty(files)
return
endif
let sesstr=join([curdir]+files, ',')
let sindex=index(sessions, sesstr)
if sindex==-1
let sindex=index(sessions, '')
endif
if sindex==-1
let sesname=os#JoinPath(sesdir, len(sesdirs).'.vim')
call add(sessions, sesstr)
else
let sesname=os#JoinPath(sesdir, sindex.'.vim')
let sessions[sindex]=sesstr
endif
execute 'mksession! '.fnameescape(sesname)
call writefile(sessions, sesfile, 'b')
endfunction
let s:_functions['s:MakeSession']=function('s:MakeSession')
function s:LoadSession(bang, ...)
let [sesdir, sesfile, sessions, sesdirs, sesfiles,

let dirsessions=[[+a:1, sesdirs[a:1], sessions[a:1]]]

\ '[v:key, v:val, sessions[v:key]]'),
\ 'v:val[1]==#curdir'.
\ ((a:0)?(' &&

endif
if len(dirsessions)==1 || (!empty(dirsessions) && a:bang)
let sesid=dirsessions[0][0]
let sesname=os#JoinPath(sesdir, sesid.'.vim')
execute 'source '.fnameescape(sesname)
call delete(sesname)
if sesid==(len(sessions)-1)
call remove(sessions, -1)
else
let sessions[sesid]=""
endif
call writefile(sessions, sesfile, 'b')
endif
endfunction
let s:_functions['s:LoadSession']=function('s:LoadSession')
function s:PrintSessions()
let [sesdir, sesfile, sessions, sesdirs, sesfiles,

call map(sessions,

I am going to evolve this into plugin sometime.
