[PHP-WIN] exec() without waiting for completion in Win2k
Hello,
I'm working on a web front-end for our build system. One of the
things I need to do is allow the user to start a lengthy build in the
back and continue using the web page.
Unfortunately, I can't find out how to do it. I can start the
build, but the web page won't complete loadinguntil the build
finishes (which considering it can take up to 5 hours, it's
not a good thing ;-)
I'm using Apache 1.3 under Win2k and PHP 4.2.3. I tried all
combinations of exec ("cmd /c start build"), even doing
exec ("cmd /c start build.bat"), where build.bat contains
start build. Nothing. The web page always waits for the command
to finish.
I'm running PHP as an Apache module. I tried running it as
CGI but had no luck getting PHP to work at all.
Any suggestions? It's the most important thing this front
end has to do. Without it, there would be no point to the program
in the first place.
Switching to Linux, unfortunately, is not an alternative I can
consider right now since the build itself needs to happen
in Win2k.
Thanks.

I'm afraid it didn't. Still the same problem. The page just waits for
the process to end.

No luck with that either. COMSPEC is defined as D:\WINNT\system32\cmd.exe ,
which is what I would expect.
Here's a simplified version. How about starting notepad from PHP? Can
anybody do that and have the web page finish generating before Notepad
is closed? It helps to try it out with the console version of Apache,
that way you can close Notepad by hand (instead of having to kill it
from the process list).
If anybody can get that to work, let me know. I would change my
configuration to match yours.
Thanks for all the suggestions so far.

Hmmm... Tempting, but there is one big problem. I just found out that
commands executed with AT don't have access to network drives or
settings. Some of this build process involves fetching data over the
network, so it won't work.
I even wrote a C program that calls spawn() on the command you pass on
the command line, but it didn't work either. I can't believe how
frustrating this is. All of which could have been accomplished with a
sinmple & under Unix :-(
Any other ideas? I think I tried just about everything I could think of.
Thanks.
