  89   30 Nov 2003 Konstantin Olchanski bad call to cm_cleanup() in fal.c
fal.c does not compile: it calls cm_cleanup() with one argument when there
should be two arguments. K.O.

Okey. I found the problem in db_check_record(): when we decide that we have a
mismatch, we call db_create_record(...,rec_str), but by this time, rec_str no
longer points to the beginning of the ODB string because we started parsing it.

I tried this solution: save rec_str into rec_str_orig, then when we decide that
we have a mismatch, call db_create_record() with this saved rec_str_orig. It
fixes my immediate problem (destruction of "/logger/channels/0/settings"), but is
it correct?

I would like to fix it ASAP to get cvs-head working again: our mhttpd dumps core
on an assert() failure in db_create_record() and the set of db_check_record()
changes might fix it for me.

Here is the CVS diff:

  77   01 Jan 2004 Konstantin Olchanski Poll about default indent style 
> I don't feel a strong need of giving up a "-i2"...

I am comfortable with the current MIDAS styling convention and I would rather not
have yet another private religious war over the right location for the curley braces.

If we are to consider changing the MIDAS coding convention, I urge all and sundry
to read the ROOT coding convention, as written by Rene Brun and Fons Rademakers at
http://root.cern.ch/root/Conventions.html. The ROOT people did their homework, they
did read the literature and they produced a well considered and well argumented style.

Also, while there, do read the Taligent documentation- by far, one of the most
coherent manuals to C++ programming style.

  67   14 Jan 2004 Konstantin Olchanski First try- midas on darwin/macosx
While watching "The Wizard of Oz", the greatest movie ever made, I took a shot at building 
midas on my macosx computer. After stumbling on a few small and on a few hard problems, I 
built almost everything. However, odb does not work- some further debugging is in order.

Anyway, the easy problems are:
- a few missing header files: pty.h, sys/vfs.h, malloc.h
- a few missing features in system.c (stime(), "get tape position")
- /usr/include/string.h already has strlcpy() & co.
- dbg_malloc() has inconsistent prototypes (size_t vs unsigned int)
- for reasons unknown, PVM is #defined. This flushed a bug in mana.c

A few hard problems:
- namespace pollution by Apple- they #define ALIGN in system headers, colliding with ALIGN 
in midas.h. I was amazed that the two are almost identical, but MIDAS ALIGN aligns to 8 
bytes, while Apple does 4 bytes. ALIGN is used all over the place and I am not sure how to 
reconcile this.
- "timezone" in mhttpd.c. On linux, it's an "int", on darwin, it's a function. What gives?
- building libmidas.a requires running ranlib
- building libmidas.so requires unknown macosx specific magic.

For your enjoyment, the "cvs diff" is attached. The resulting code is known to not work.

With the ALIGN8() change ODB works, mhttpd works. ALIGN8 change now commited to cvs, verified that "make all" builds 
on Linux.

ROOT stuff still blows up because of more namespace pollution (/usr/include/sys/something does #define Free(x) 
free(blah...)). Arguably, it is not Apple's fault- portable programs should not include any <sys/foo.h> header files. I 
think I can fix it by moving "#include <sys/mount.h>" from midasinc.h to system.h.

Also figured out why PVM is defined- more pollution from "#include <sys/blah...>". This is only in mana.c and I will 
repace every "#ifdef PVM" with "#ifdef HAVE_PVM". Is there documentation that should be updated as well? Alternatively I 
can try to play games with header files...


> But take into account that using "//" for comments might cause problems for the VxWorks compiler (talk to Pierre 
about that!).

Yes, "// comments" stay out of midas. I used them to make the modification more visible.

> You can rename ALIGN to ALIGN8 all over the place.

Done, commited.

Right. Still on the todo list.

I still have to cleanup the Makefile. Not commiting it yet.

Then, a new problem- on MacOSX, pthread_t is not an "INT" and system.c:ss_thread_create() whines about it. I want to 
introduce a system dependant THREAD_T (or whatever) and make ss_thread_create() return that, rather than INT.

ROOT stuff is still not fully tested- it takes a little while to build ROOT on a 600MHz laptop.

Attached is my current CVS diff.

  71   18 Jan 2004 Konstantin Olchanski First try- midas on darwin/macosx
> I would like to keep all OS specific #includes in midasinc.h

No go. Here is the problem:

midasinc.h includes sys/mount.h, which #defines Free(x) to be something else
mana.c includes msystem.h, which includes midasinc.h
mana.c includes ROOT header files, which blow up because Free(x) is redefined.

I want this:

mana.c does *not* include sys/mount.h
system.c does include sys/mount.h

Simplest solution is to take sys/mount.h out of midasinc.h and include it in system.c

Commited.

Okey. In Darwin, pthread_t is not an int. It is a pointer to a struct. In midas.c I typedef midas_pthread_t to HANDLE on Windows and to pthread_t n OS_UNIX.

This uncovered a problem with ss_getthandle(). What is it supposed to do? On Windows it returns a handle to the current thread, on OS_UNIX, it returns getpid(). 
What gives? I am leaving it alone for now.

Attached is the current diff. Most changes are in system.c: ss_timezone() and midas_pthread_t. The Makefile part is already commited. Building the shared 
library was made dependant on NEED_SHLIB. Now, building static midas applications is very simple, use "make SHLIB="

Done.

With this, I commited the rest of my changes: midas_thread_t in midas.h, change ss_thread_xxx() prototypes in msystem.h
, implementation in system.c

My cvs diff is now empty.

Midas should compile on Darwin aka macosx, I tested "odbedit" and "mhttpd"- they seem to work.

I do not want to touch this. Sorry.

  66   19 Jan 2004 Konstantin Olchanski darwin aka macosx changes
I commited the final bits to make Midas build on Darwin aka macosx.

Here is the summary:

1) I treat Darwin as a funny linux, so OS_LINUX is always defined
2) OS_DARWIN is defined for places where the two differ
3) system dependant directory is "midas/darwin/{bin,lib}"
4) a few header files had to be moved around to dodge namespace pollution by Apple system 
header files (i.e. one of the PowerPC header files #defines PVM- collision with PVM in mana.c, 
another #defines Free(x)- collision with ROOT header files)
5) ss_thread_create() and ss_thread_kill() now use midas_thread_t. On Darwin ptherad_t is not 
an "int".
6) the Makefile has no support for building the midas shared library on macosx.
7) on my Mac OS 10.2.8 machine, "make all" works, "odbedit" and "mhttpd" run. This is the 
full extent of my testing. Status on Mac OS 10.3.x is unknown.

K.O.
  64   30 Mar 2004 Konstantin Olchanski elog fixes
I am about to commit the mhttpd Elog fixes we have been using in TWIST since
about October. The infamous Elog "last N days" problem is fixed, sundry
memory overruns are caught and assert()ed.

For the curious, the "last N days" problem was caused by uninitialized data
in the elog handling code. A non-zero-terminated string was read from a file
and passed to atoi(). Here is a simplifed illustration:

char str[256]; // uninitialized, filled with whatever happens on the stack
read(file,str,6); // read 6 bytes, non-zero terminated
// str now looks like this: "123456UUUUUUUUU....", "U" is uninitialized memory
int len = atoi(str); // if the first "U" happens to be a number, we lose.

The obvious fix is to add "str[6]=0" before the atoi() call.

Attached is the CVS diff for the proposed changes. Please comment.

K.O.

  62   28 Apr 2004 Konstantin Olchanski mhttpd "start run" input field length?
I am setting up a new experiment and I added a "comment" field to "/
Experiment/Edit on start". When I start the run, I see this field, but I
cannot enter anything: the HTML "maxlength" is zero (or 1?). I traced this
to mhttpd.c: if (this is a string) maxlength = key.item_size. But what is
key.item_size for a string? The current length? If so, how do I enter a
string that is longer than the current one (zero in case I start from
scratch). I am stumped! K.O.
  58   07 May 2004 Konstantin Olchanski min(a,b) in mana.c and mlogger.c
When I compile current cvs-head midas, I get errors about undefined function
min(). I do not think min() is in the list of standard C functions, so
something else should be used instead, like a MIN(a,b) macro. To make life
more interesting, in a few places, there is also a variable called "min".
Here is the error:

src/mana.c: In function `INT write_event_ascii(FILE*, EVENT_HEADER*, 
   ANALYZE_REQUEST*)':
src/mana.c:2571: `min' undeclared (first use this function)

   function it appears in.)

  52   22 Jun 2004 Konstantin Olchanski How to compile under Darwin-gcc? (MacOS X)
The current (cvs) version of MIDAS should build on Mac OS X right out of the
box- I fixed all the problems you report back in February(?)- see the macosx
thread in this forum. A few weeks ago I verified that it still compiles on Mac
OS 10.3.4. The Mac OS port received minimal testing- I checked that "odbedit"
and "mhttpd" run, that's about it. K.O.

Fixed. Good catch.

You will have to read the "ld" manual. In the nutshell, it tells the executable where to look for shared libraries. 
Aparently it is not supported by Mac OS X.

I use:

setenv CVS_RSH ssh
cvs -d cvs@midas.psi.ch:/usr/local/cvsroot checkout midas

It works most of the time. Sometimes I get locking and "permission denied"
errors on some subdirectories, presumably when CVS is being reorganized or
when there are stale locks. Does not happen too often.

  48   14 Jul 2004 Konstantin Olchanski install problem of Makefile on MacOS X (Darwin 7.4.0, gcc 3.3)
> There are not such a file "io.h" inside my MacOS X. In fact, I didn't find any file containing function iopl().
> So what is the equivalent function of iopl() under MacOS X? The utility dio should be modified in order to be compiled under Darwin-

"dio" is not supported under MacOSX. It is used to grant user programs access to PCI and ISA cards (usually CAMAC interfaces). We have
no MacOSX hardware with PCI or ISA slots so we cannot test and support this functionality.

The MacOSX Makefile should not try to build "dio". I will accept a patch to fix this Makefile bug.

K.O.
