[Lazarus] very small addition to multilog package
I've been using for long the great multilog package to do selective logging to file and an IPC listener.Recently I needed to setup a little more complicate IPC based system, for which I took advantage of all of that good work. In order to have a multiple agent bi-directional communication was to be able to give a different name to each server. So, if anyone is interested in it or you want to include it in the "standard" multilog package, I am attaching ipcnamedchannel.pas It is nothing more than a copy of the standard ipcchannel.pas with a change in the constructor a little else. This possibility could be very well integrated in the standard TIPCChannel class with a second constructor, but I simply preferred not to touch the original file. Bye, R# ipcnamedchannel.pas Description: Binary data -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Yes, some people do that. It is not recommended. The packages in the Lazarus sources do not share directories - neither source, nor output.

Let's say, would be less necessary. it clean auto didn't have a flaw in how package compilation is handled in TLazPackageGraph. In a situation where lazarus tree is not writeable, and a different user path must be used, what happens currently is: 1. TLazPackageGraph.CheckIfCurPkgOutDirNeedsCompile checks from lazarus tree if the compilation is required. 2. If yes, it verifies if normal output dir is writeable. The check fails, and it uses the FallBackOutputDir with SetDirectoryOverride. Compilation output goes in the user path, and overwrites possible old ppu's and resources. That's OK. 3. If no compilation is required, compilation is skipped, and anything leftover in the user path remains untouched. That's the flaw. What exactly is flawed? 4. When linking user path takes precedence over lazarus tree path (newly compiled must take precedence over old ones), and invalid leftovers abort the linking. The issue can be solved by brute force, always forcing the compile when normal output dir is not writeable, or with more elegance, by checking also the fall back output dir before deciding if a new compilation is required. Do you mean line 3237? I rather mean line 3206. If normal output directory (i.e. the not writeable one, in our case) doesn't need compile, no check is made on the fall back directory.

If, with that, you get a complete portable embedded RDBMS which is 1:1 compatible with it's big server-brother my choice is easy. Interesting. I don't know how firebird works without its .conf file, perhaps it has default value for everything. The config file supplied doesn't have *any* settings in it. They are all commented out because they are all default in the .dll itself. The file is only supplied as an example to what you can change in the rare instance you need to.
