Loading a mapfile from a string...

[Tamas Szekeres]

Steve,

When building the CVS-HEAD on Windows I got:

 Creating library mapserver_i.lib and object mapserver_i.exp
mapfile.obj : error LNK2019: unresolved external symbol
_msyylex_destroy referenced in function _msLoadMapFromString
libmap.dll : fatal error LNK1120: 1 unresolved externals
NMAKE : fatal error U1077: 'link' : return code '0x460'
Stop.

Is this problem related to this change?

Best regards,

Tamas

> Only one comment (and positive at that) so... this has been commited. One caveat is that to avoid leaking memory yylex_destroy is being used to clean things up. Apparently this is available in newer versions of flex. May actually be there in old versions but only if a reentrant scanner is being built. Presents a small problem. We can control the distributions by using a newish version of flex when building things for users. Requiring developers to use version x.x.x (I'm at 2.5.31) doesn't seem to big a hardship. Thoughts?

> Hi Folks: I've been screwing around with getting mapserver to ingest a mapfile stored in a string buffer rather than a file. In theory you could build up a configuration from text snippets or database output rather than manipulating objects directly. The code could almost do this in the past but needed some reorganization to re-use as much as possible. The result is a new function called msLoadMapFromString. I took the opportunity to fix some naming wierdness in mapfile.c and to clean up lexer initialization a bit. In otherwords I'm sitting on a fair number of minor changes to mapfile.c and maplexer.l (with a few other small edits elsewhere). Is this a big enough deal to warrant a RFC or can I just commit?
