Will be there any D5 service pack 2 ??? - test4711.zip (0/1)

>How can this problem be reproduced?
OK,
this is the first reply to this issue......
But we are here in the non-technical aera......!!!!! where I asked for
a non technical question....
and you will find ATTACHED a project group with projects given using
the delphi 5 demo source...
copy simple the unzipped test4711.zip (2k in size) to the demo path!
Use W2k Sp1 with 128 mbytes :
- open task manager
- open delphi with the test4711 group and have then 22 Mbytes memory
used
- build full group and have finnaly have used 60Mbytes (this will go
worst depended of the source size and project count count
A suggestion for Borland news group :
a) a pure bug discussion area
b) a pure suggestion area
c) open access to the bug database
d) give REAL answer to given bug reports
(not automatically generated only)
cheers

Sure - unit caching. Now, if that increased steadily from 60 MB, and if it
didn't drop back with a new project group, then this would be a leak.

I just recorded the following memory used amounts, as reported by Task
Manager:
Delphi after startup: 192 MB
After "compile all" (5 projects in group): 292 MB
Switch to another project group: no change
Compile all with new group: 295 MB
IOW, compile all used 100 MB, which was not released when a new project
group was loaded. However, it did seem to be re-used on the next compile.
Why would units (or anything else, for that matter) need to be cached to
this extent after a compile? My memory "limit" is around 310 MB, according
to task manager. I quite frequently surpass that figure (and get a dialog
box talking about increasing virtual memory) during a large compile or build
all. I'd much rather have the compile, link, or whatever take a little
longer as opposed to using up all my memory until I shut down Delphi.
btw: system is
W2K sp1
128 MB RAM
333 mHz PII

Try minimizing Delphi between the two compiles. Task Manager is not a memory
leak detector and was never intended to be used as such. All it reports is the
amount of available memory. Freeing memory does not force Windows to reclaim it
immediately and therefor the task manager seems to be reporting a leak. A few
events will cause windows to sweep the heap and reclaim freed memory.
Minimizing the main window of an app is one of these events.
For example. I have a project that task manager starts at 6,448 KB used. After
compile it is 39,036. Compile again it is 39,232. Now minimize Delphi and have
the Windows memory manager sweep for freed memory by Delphi and it drops back
down to 1,764 and restore Delphi and it goes right back to 6,260 (this sometimes
takes 30-60 seconds after the compile for windows to actually catch it for
sweeping).
What you are seeing is the effect of Windows not returning freed memory
immediately to the heap which is what the Task Manager is monitoring. Stefan is
correct that Delphi does cache the units until all the builds are done, but that
memory is released after all the projects are compiled.

It isn't, only cached during the compile of all the projects. See above.

Performance - fast code completion, tooltip symbol insight, linking, ...

Suggestion: Increase the size of your swap file - yes, this is only a
work-around.

IOW, less aggressive caching?
Could you characterize the project group you have trouble with, together
with your D5 environment?
> Delphi after startup: 192 MB
Let me characterize mine:
Memory usage as indicated by the W2K SP1 task manager after startup of D5
SP1: 153 MB. *But* I have running
* three instances of Forte Agent
* four instances of IE 5.0
* ZoneAlarm
* a TV viewer
* LeechFtp
* a largish application
Please do not misunderstand me, but looking at the information you
supplied
> Delphi after startup: 192 MB
> 128 MB RAM
your system is by far too overloaded.

An aside question: How did you attach that? My newsreader
thingie is *not* set up to get attachments, but I got this one
anyway...

4711 is the number of the original "Eau de Cologne". The company is in
4711 Glockengasse, Cologne.

That's true, but I haven't seen it in heavy use other than at my school
in Stockholm, Sweden. 17 and 4711 are their favorite "random" numbers.

Here in Germany, people use 4711 as a "cute" number, e.g. on number
plates. Here it definitely means the Cologne.

Oh well... So much for being "special"... <g>
