Minimize rebuild time #20

Open vadz opened 3 years ago

vadz commented 3 years ago

This is an internal issue, i.e. it doesn't affect the users at all, but rebuilding Extrema after any change takes inordinately long right now because just about everything is recompiled due to bad/inefficient physical structure of the project: basically, all sources files include many (or even most) of the headers, so any change anywhere requires recompiling them.

This almost certainly could be drastically improved by avoiding the unnecessary dependencies and using forward declarations more (AFAICS they're hardly used at all currently).

It would still require some time to do it, of course, but I think it will be compensated relatively quickly by the time saved on waiting for the rebuild to finish...

A possible first step (also alluded to in https://github.com/esternin/eXtrema/issues/58) would be to skip assembling the objects into libraries after a single object recompile. And certainly not re-doing the libraries from other subgroups. For example, changing one of Commands/*.cpp files results in this:

...
libtool: link: ranlib .libs/libcommands.a
libtool: link: ( cd ".libs" && rm -f "libcommands.la" && ln -s "../libcommands.la" "libcommands.la" )

which seems appropriate, but then it goes on:

/bin/sh ../libtool  --tag=CXX   --mode=link g++ -I../../src -I../../src/Commands -I../../src/Expression -I../../src/Functions -I../../src/Graphics -I../../src/Operators -I../../src/Parsing -I../../src/Utilities -I../../src/Variables -I../../src/wxForms -I/usr/local/lib/wx/include/gtk3-unicode-3.2 -I/usr/local/include/wx-3.2 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL -D__WXGTK__ -pthread -DHAVE_MUD -I/work/edik/mud/src  -std=c++11   -o libextrema.la -rpath /usr/local/lib  libcommands.la libexpression.la libfunctions.la libgraphics.la liboperators.la libparsing.la libutilities.la libvariables.la libwxforms.la

libtool: link: ranlib .libs/libextrema.a
libtool: link: rm -fr .libs/libextrema.lax
libtool: link: ( cd ".libs" && rm -f "libextrema.la" && ln -s "../libextrema.la" "libextrema.la" )

which as far as I can tell reindexes all of the sublibraries, not just libcommands, and then the extrema.la library, and only then the executable.

Is this really necessary?
