[Bug 46269] New: Metatrader 5 File handlers aren' t flushed when calling FileFlush() / flush

Bug ID: 46269
           Summary: Metatrader 5 File handlers aren't flushed when calling
                    FileFlush() / flush
           Product: Wine
           Version: 3.0.3
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: wineserver
          Assignee: [e-mail]
          Reporter: [e-mail]

Hi guys, there's a problem with metatrader 5 file handlers
All calls to FileFlush / fflush aren't flush to disk
A file being openned to shared read, can't be read since data isn't at disk, in
other works no one see new data until application close. after application
close all data can be read, but if application close with a signal (kill
<pid>), all filewrite operations are lost

I can share some examples if you need, but the easiers is

start terminal64.exe with:
terminal64.exe /portable

read logs/<current day>.log
file with "tail -f logs/..."
you don't see anything
close the metatrader window with "X" windows button
now you can see data at file

i don't know if wineserver have a buffer at memory or temporary files, but it's
a bit strange. the normal windows behaviour is write to file at each
"fileflush" / fflush operation, wine is working different

doing some research...

from IRC chat:

ircuser 20:58:19
> zf_ fileflush is working
> the problem is pobably other
> maybe winserver is caching it, or system cache isn't being save to disk on a regular time basis or someting like, i don't know if it's the default standard of windows
> i tested my script now with strace on linux, it don't work, but without strace it works
> what i did.... i open the metaeditor (a metatrader ide to create programas), and run a debug mode
> f11, on each line
> when i do f11 at FileFlush, at the console i see 0,1,2,3,4... using a "tail -f BUG46269-1.txt"
> probably the problem isn't at FileFlush at expert advisors or scripts
> the problem is at Metatrader logging file, the logs/<date>.log isn't flushing, that's a metaquoets problem probably, but i don't know how to solve, >i will strace it and check what happens
> news i post again here
