Created Issue: Obvious memory leak under Win32

bug — Tue, 23 Sep 2008 07:31:03 GMT

From the function "process_cla" in slib.c (comments added):

<pre>
if (!siod_lib_set)
{
#ifdef WIN32
if (argc > 0)
/* strdup() uses malloc(), which means that
* siod_lib, allocated below, must be freed:
*/
{siod_lib = strdup(argv[0]);
siod_lib_set = 1;
if ((ptr = strrchr(siod_lib,'\\')))
ptr[1] = 0;}
#endif
if (getenv("SIOD_LIB"))
/* The buffer siod_lib is being assigned a new value (below).
* Under Win32, its old value (which still needs to be freed)
* is lost.
*/
{siod_lib = getenv("SIOD_LIB");
siod_lib_set = 1;}}
#endif
</pre>

BTW, I ran across this while trying to figure out why my linear-time Scheme script runs in exponential time under GIMP's Script-Fu.

CLOSED ISSUE: encorporate the hostile foreign-function interface

CREATED ISSUE: build problems, siodffi failure on other computers

publius — Mon, 14 May 2007 16:49:34 GMT

require-so 'RealLoad.dll gets an error, with errobj detail providing "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. " If you try to start the DlgSIOD.exe you get the same error message. The release 3.6.2 was compiled on a machine running Microsoft Windows XP Pro, with Visual Studio 2005 C++ Express edition and the "Microsoft Platform SDK for Windows Server 2003 R2" Note that RealLoad.dll and DlgSIOD.exe use C++. If you go to a machine with Visual Studio 2003 on it, run the BUILD.BAT and then copy all dlls and exe from the Release folder up one level to the SIOD folder, then things work ok. So this might be a problem from dll hell.

CREATED ISSUE: compare against siod.tgz ports bring in fixes

The siod.tgz represents code for the other non-windows ports. Some files are duplicated and others have been forked, with some work taking place in Solaris and Linux. This can be downloaded from http://alum.mit.edu/www/gjc/siod.html and compared against the sources on codeplex. Review all differences and make sure that no bug fixes or features have gone missing in the winsiod version.

CREATED ISSUE: move old platform-specific files to archive folders

publius — Wed, 25 Apr 2007 21:21:44 GMT

The source code still has files in it that are needed only for some of the more obscure platforms such as the classic macintosh, vax and alpha vms, amiga, and ms-dos. Move this code to some archive folders.

CREATED ISSUE: cleanup of ugly for no good reason code

publius — Wed, 25 Apr 2007 21:21:43 GMT

Some code is ugly for no good reason. (The only good reason to be ugly is the conservative garbage collector). For example, the READ built-in uses a horrid little global string token buffer. Some parts of eval are difficult to read for no good reason. Often because of optimization work that was done without removing code that turned out to be not so optimal. This task is to make issues for each ugly part and to prioritize them for fixing. Packaging for multi-threaded operation is not included here. It is important to remain single threaded so as to not become assembly language in C syntax.
