[fpc-pascal] Best practice for getting heap usage summary
What is considered best practice for getting a summary of heap usage, in a single-threaded program which doesn't need to be Delphi-compatible? In Delphi programs that have had to run for an extended period I've used AllocMemCOunt() and AllocMemSize(). What's the best way of getting something comparable for FPC- THeapStatus.TotalAllocated etc.? -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Maybe you mean GetFPCHeapStatus http://lazarus-ccr.sourceforge.net/docs/rtl/system/getfpcheapstatus.html There is also the Delphi compatible GetHeapStatus, but only for 32bit.

[fpc-pascal] IPTables log parser?
Hi list, I noticed ik has started a project to manipulate Linux iptables firewall rules... which got me thinking. Is there any FreePascal/Delphi code lying around to parse IPtables log output (e.g. in the /var/log/messages syslog file), e.g. into CSV format? If not, I'll probably write my own... sometime... as I'm interested in importing the stuff into a database using my favourite tool. Yes, I like reinventing the wheel but: 1. I could use existing suff, e.g. the dshieldpy python project, dshield.py, parse function... 2. Reinventing wheels can be fun and a learning experience...

The above is a direct RTL call. But note that a) it is buggy in case of multi-threaded programs: http://bugs.freepascal.org/bug_view_advanced_page.php?bug_id=14315 b) it won't contain any information at all if you use cmem or another memory manager that does not keep track of allocation information.

I presume you're aware of logging via ulogd, which at least helps split things out a bit. One marginally-related thing is visualising iptables' connection tracking using Doomcube, that could be improved enormously using an Elite-style display. [Grumble] Command-line handling of iptables can be irritating since setting up a rule doesn't give you a unique tag you can use to delete it. I've had a situation in the past where I no longer knew the addresses etc. when it came to tearing a rule down, which caused problems. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

I presume you're aware of logging via ulogd, which at least helps split things out a bit. Thanks, both of you! Yep, I'm aware of ulogd; however I prefer not installing stuff/tweaking things on my router if I don't have to. Didn't know about libnetfilter_log; I might indeed have a look at libnetfilter_log to see if I can incorporate that into my FPC program. If I do, I'll get back to you, Ido. The alternative would be to parse the syslog output which I was thinking about. Though it's not very pretty, the advantage of that is that I can forward my router's syslog to another (database,... whatever) host and run the extraction there...

[fpc-pascal] detect the version of fpc that a feature added to it
Hello, I was looking to understand in what version of FPC ($IF defined ... } was added, and realized that it is not very simple to detect such information. So beside this question of when was it added ? What is the best way to find such information ? Another question, should I open a bug for documentation, to add when a specific feature like so was added in the documentation itself ?

In our previous episode, ik said: I was looking to understand in what version of FPC ($IF defined ... } was added, and realized that it is not very simple to detect such information. True. SVN logs of documentation and compiler is the easiest. But that can be exhausting. But $if is old. Wouldn't be surprised if the 2.x series all supported it. In general I usually define the oldest version I want to support (now 2.4.4, but from experience 2.4.2 usually works too), and dl and test with that version (and intermediate ones). Daniel: this is a language feature, the bugreport is about the same problem for libraries. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] How to get path to current theme icons on linux?
2012/1/18 Krzysztof dib...@wp.pl: Another problem. I know path to current icons, but icons are named like office-spreadsheet not by extension and can be in svg format :/ Read this: http://standards.freedesktop.org/shared-mime-info-spec/shared-mime-info-spec-latest.html There is a file globs that contains a mapping from names to MIME types. Therefore you can map for example pdf to x-office-spreadsheet. Look at sample code in function TPixMapManager.LoadMimeIconNames in http://doublecmd.svn.sourceforge.net/viewvc/doublecmd/trunk/src/platform/upixmapmanager.pas Once you have MIME name look here how to find the icon location in the icon theme: http://doublecmd.svn.sourceforge.net/viewvc/doublecmd/trunk/src/platform/uicontheme.pas -- cobines ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
