v5.2.8 Delphi XE7 PDF Export Memory Leaks

Polomint

FYI I have raised a ticket on FR5.2.8+ / D21 for consistent memory leaks on app closure after one or more FR->PDF exports.

The leaks seem to be a new problem, as they weren't evident in FR5.2.4 (and FR5.2.7 caused AVEs).

Cheers, Polomint

UPDATE:

Still a problem with FR5.2.10 - FR5.2.17

Polomint

And still happening in 5.2.11...

And still and issue in 5.2.12, but seemingly a whole lot worse (!)

Using 5.2.10 when I save a 50 pages document in PDF I have a memory increase of about 200MB for each save. This is a disaster even for a desktop app. For a server I have no words....
I think that someone do not bother because it took me half a day to patch it in 7 places and memory leaks are gone.
There are more GetMemory() stored in the same pointer TfrxPDFFont.FontData and only one FreeMemory() at the end.
Also TrueTypeFont.Indices is not freed.

Best regards,
Cristian Peta

Have you tried the 5.2.15 update Christian? It has improved significantly, although still not 100%

I don't have the source, so am unable to fix this myself!

I will try it for the next version of our app in other VM with XE8....
But currently I have no leaks and it is in production and stable. I don't need troubles.

Amen!

I note that 5.2.17 is much the same as 5.2.15...

From my tests, the problem still exists in 5.2.18 also (in D2007 at least)

And it is still present in 5.3.0 [img]style_emoticons/<#EMO_DIR#>/sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> I note also that the D2007 compiler raises several warnings in regard to loss of information due to "narrowing" of widestring constants in frExportPDF.pas ...[/img]

Is there any fix for this in 5.3.3?

I tried it today and reliazied that none of my pdf exports workded corectly. (All the letters was replaced with dots ".")

Did you export to PDF with embedded fonts option?

GeorgeB

No. I don't use embedded fonts because raises the size of pdf significantly.
Of course the fonts i use are common windows fonts.

Polomint

Not sure your problem relates to this topic. Is the problem causing "Memory Leaks"?

If so I think it is a new issue, because my limited testing of 5.3.3 suggests the original leak problem (that I created this topic for) has now been fixed.

Polomint

I have closed the "ticket" on this. FR v5.3.5 for Delphi XE7 seems to have successfully addressed the problem, at least on the full test of my application in Debug mode.
