Re: Getting a / when regex should produce nothing
Thank you, AW, for a well-written summary of the aspect of
mod_perl that causes the most difficult/nasty bugs for people.
But you left out one important caveat which could scare away
more potential users than it saves.
The retention of values from previous executions applies
only to global variables. Specifically:
- when the script terminates, whatever is in the *global*
variables stays there.
it remembers your compiled script, and the state of its *global*
variables from the last execution
The big danger is that your *global* variables start with the
state in which the previous run
Programming pundits have been discouraging the use of global
variables for years now, perhaps a little more strongly than
is good for the state of the art. However anyone feels
about that, it's useful to write out some guidelines:
* Use global variables for information that you specifically
want to save across executions. The best case is for items
that are defined during the first execution, then used in
later executions.
* If you want to use a global variable for some other reason,
be very careful and aware that it may start an execution
with a value from a previous execution.
* Put most variables inside of subs (including handlers).
These will be initialized for each execution just as in
other perl contexts. Most people have come to accept a bit
more parameter-passing to subs than would be necessary with
global variables, for this initialization plus avoiding
inadvertent bugs when one forgets a global variable name.
A technique that I've used to avoid problems (particularly
when converting old CGI scripts) is, given a list of global
variables at the start of the module:
my ($var1, $var2, $other_var);
my $inited_var = 123;
write directly thereafter:
sub init_vars {
undef $var1; undef $var2; undef $other_var;
inited_var = 123;
}
and call init_vars just before each exit from each handler.
Even easier though to me less satisfying, call init_vars right
after entry to each handler.

Perl and nod_perl are very deterministic, and there is no mystery
in what they do with variables. The trick is to understand exactly
how mod_perl works, and how this plays along with the way Apache
(in its different MPM variations) works.
This particular issue has taught me two things.
I am never going to use no warnings 'uninitialized' again. It is
too dangerous to be overlooking possible problems.
I agree.
Maybe even do as Michael said, and make all warnings fatal, if we
are talking about user/web oriented applications.
It has also taught me that perl itself may leave values in
variables such as $1, even after a server stop and start and first
running of a program.
That however, is definitely not the case.
If you stop and start the server, you have a totally new
environment, and there is nothing left from the previous one.
If you are using a "prefork" version of the Apache server, then
that is also true each time an Apache child ends and a new one is
started : it gets a "new perl" and a new set of variables.
(but the thing is, you mostly cannot predict when Apache will start
a new child, nor which child will handle which request).
For other Apache configurations, the situation may be a bit more
complicated.
The main aspect to understand with mod_perl (as opposed to running
a perl program without it) :
- when you run a perl script without mod_perl, the sequence is :
- a new perl interpreter is started, clean
- your script gets compiled, and gets a brand-new set of variables
- your script gets run, starting with this new set of variables
- your script "exits"
- perl exits, and returns all its memory to the OS
.. and the next time you run your script, the same steps happen.
under mod_perl :
- an Apache child starts, and it gets a new perl
- your script gets compiled, the first time around. That time, it
gets a brand-new set of variables.
- your script gets run, the first time, with these brand-new
variables.
- when the script terminates, whatever is in these variables
stays there.
- the perl interpreter inside that same Apache child stays alive,
amd it "remembers" the compiled code of your script.
Now is the difference : when a new request comes into Apache, and
(as may happen) it is sent to the *same* Apache child, it is
processed by the same perl interpreter. And that one is not
"clean" : it remembers your compiled script, and the state of its
variables from the last execution. And that is where it starts from.
The big gain is that perl does not have to compile the script
again, it can run the compiled code ri

Re: global variable
Hi, IPC::MMA and its underlying MM library are written entirely in C. I originally got into this business when I read some user reviews that said that the predecessor module IPC::MM was the fastest module of its kind that they could find. IPC::MMA cleaned up several things in IPC::MM, including generalized keys as in Perl hashes. (IPC::MM only allowed C strings as keys.) IPC:MMA is probably faster than IPC::MM. But I've never done any benchmarks to back up this claim, nor against other modules. The direct-call interface is inevitably slightly faster than the tied interface. IPC::MMA only allows sharing among parent and child processes, including between children. The general idea is to create the shared memory, and most or all of the data structures, in the parent process before it forks (e.g., in an Apache PostConfigHandler). If the relationship with the backend daemon isn't parent:child or child:child, you can't use IPC::MMA to share data with the backend daemon. I have to plead ignorance of the fine points of typeglobs. I've used the * notation when an example told me to, without thinking much about it. Having read all the 'typeglob' references in Programming Perl and those in the perl internal docs, they sound like data structures containing addresses of things, i.e., references to things. Except for addresses in shared segments, one process can only access the content of its own memory via addresses, not the memory of other processes. In C, filehandles are just integers, which are eminently sharable.

Re: global variable
Just thought to add: One of the most interesting uses of IPC::MMA is to create a shared memory in a PerlPostConfigHandler, and then use it to tie scalars or arrays or hashes in other modules into the shared memory. In write-seldom, read-mostly applications like the cache hash in Image::Size, this can be done without any change to the other module. cmac On Feb 3, 2010, at 9:20 AM, Boysenberry Payne wrote: Looks like a great module.

Been away from my computer for several days :( Doesn't look like anyone is going to answer this. Maybe you missed some of the emails that Clinton Gormley and I were exchanging a while back. I've been using 'sudo apachectl graceful' on apache 2.2.11 and 2.2.13 with mod_perl 2.0.4 and 2.0.5 SVN for many months now and have not noticed any problems. Of course you might be using some feature or module or ??? that my site doesn't, which would cause some problems. Fancy SSL use and changing certificates were mentioned as possibilities. If you look thru the change logs for the various apache versions you can see quite a few improvements for graceful and other restarts (there was one in 2.2.12). So why not give them a chance, and if you have problems come back here and tell us? Or look into them a little and come back and tell us even more?

Re: double mod_perl initialization
You can find changes about graceful restarts in many of the version release notes in apache2. My memory is that 2.2.11 was OK for me. Letter -Os means "optimize for size": http://gcc.gnu.org/onlinedocs/gcc-2.95.3/gcc_2.html#SEC10 is the oldest gcc manual I could find, so the option has been around for a long time. On many compilers (including apparently gcc-x86) it also does better on speed, unless you use -O3 which can inline your memory size up. You want to get a compiler guy annoyed, suggest that his compiler's "optimize for size" is faster than its "opt for speed". For building perl, you add '-Doptimize=-Os' to the Configure command line. For building Apache, you put '-Os' in CFLAGS at configure time (possibly with other CFLAGS you may like). mod_perl inherits it from perl or apache. Other XS (C) modules inherit it from perl. You can see either -O or -g (debugging) in most cc commands. I tried -Os last week on my one CPAN module (ExtUtils::MakeMaker suggests it). It took the size down between 10% and 15%. The perl binary shrank in that range too. The impact on the httpd process size is less, but there's lots of data in there. So far there's also less in my error_log, but that's probably coincidence :-) Enjoy, cmac On Sep 26, 2009, at 10:36 AM, Clinton Gormley wrote: You are 4 releases behind.

However, since I was a young mod_perl lad I've been taught never to rely on graceful restarts, and always to stop/start. This happens right along: * a bug is found in a piece of software, * the bug gets publicized and responded to and remembered by many people, * the people maintaining the software fix the bug, * but for months and years into the future, people remember the bug and keep working around it. Apache's graceful restart worked fine years ago, but started losing badly at some point. I probably wasn't the only person to write a script called 'graceful' to use instead of 'apachectl graceful'. My log rotation script still uses a variant of 'graceful', but that's mostly because it determines when it's OK to process the log. But at some point, several iterative fixes by the Apache crew had succeeded such that 'apachectl graceful' worked better than my 'graceful' script in some way. It was sufficiently long ago that I've forgotten in what way, but the memory is clear enough that I think Messrs. Swartz and Clint are beating a dead bug. I use 'apachectl graceful' a lot, and can't remember a problem for a long time. Of course problems still exist with older versions of apache2. If they work, graceful restarts are a good thing in that they're as nice as possible to users on a production web site. Double initialization does not prevent problems with restart (graceful or otherwise) for most configuration or perl problems. Isn't that because by the time the root httpd starts the first (re) initialization it has already notified the children (that use the old configuration and code) to go away? So if restart is the reason for double initialization, by all means let's encourage the Apache folks to reconsider the idea, and work around it until they do. cmac P.S. sudo's were omitted for brevity.

Fred Moyer and Michael Peters were correct about not wanting to have 5.8.x libraries under perl 5.10.1.

So when you've upgraded between say 5.8.2 and 5.8.7 you wouldn't need to re- install. But when upgrading from 5.8.X to 5.10.X you will need to re-install. If you aren't up to being rigorous, be lucky: everything (except mod_perl build, see crossed email with "resolved" in title) works for me so far. Hopefully most modules for which this would be an issue are covered by upgrades, which get installed at the top (5.10.1) level. What does make problems is that CPAN sometimes deletes modules in an earlier-version directory when installing a new module in the current-version directory. This tends to break the lower-level perl w/r/t module availability. So I copy the earlier-version directories before an upgrade session, and run a "sync" program thereafter. Aside from the pain of re-downloading all kinds of modules as they prove to be needed over the next year or so, I know there are items in the 5.8.7 libraries from my Internet Hosting Provider, that are needed to run software from the IHP. If you need 5.8.7 libs that you can't re-compile against 5.10.1 then just stick with 5.8.7. I had a case like that in the current transition: my IHP's CGI control panel works under 5.8.9 but logs taint warnings under 5.10.1. So I just ran a script that changed all of its bang lines to 5.8.9. Sometimes one has to admit that life is too short to tilt with every problem.

Yes, the perl you use when you run the Makefile.PL is the one that's used in the compilation of mod_perl. Thank you for this valuable information! It should be in the mod-perl documentation. (Bet it's not in there now, I looked pretty hard.) Hope someone who can do that reads this suggestion. -- Michael Peters Plus Three, LP
Re: Undefined symbol "Perl_pad_sv" building mp2 (resolved but all not well)
Hi Fred, Decided to look at the source found by your 'ack'. It turns out that, in file pad.c, someone in the perl 5.10.0 or 5.10.1 project decided that the Perl_pad_sv routine was only needed if -DDEBUGGING was specified for the Perl build. Fixed this by commenting out the #ifdef DEBUGGING at line 915 of pad.c and the #endif at line 966 of pad.c. (These weren't there in 5.8.9.) Then the compile of pad.c didn't work. A macro used by one of the two newly-included routines was missing. Fixed this by commenting out the #ifdef DEBUGGING at line 6076 of proto.h, and the #endif at line 6082 of proto.h. With these changes perl5.10.1 built, passed all its tests, and installed fine. It works in various scripts too! On to testing mod_perl2. Did make veryclean, perl Makefile.PL, and make without any hangups. (There were probably some warnings during make but I didn't watch carefully.) make test no longer gets the "Undefined symbol Perl_pad_sv". Unfortunately it now fails in a different way: == animalhead:/build/mod_perl-2.0.4 $ make test cd "src/modules/perl" && make /usr/bin/perl -Iblib/arch -Iblib/lib t/TEST -clean APACHE_TEST_GROUP= APACHE_TEST_HTTPD= APACHE_TEST_PORT= APACHE_TEST_USER= APACHE_TEST_APXS= /usr/bin/perl -Iblib/arch -Iblib/ lib t/TEST -bugreport -verbose=0 /usr/local/apache2/bin/httpd -d /build/mod_perl-2.0.4/t -f /build/ mod_perl-2.0.4/t/conf/httpd.conf -D APACHE2 using Apache/2.2.13 (prefork MPM) waiting 120 seconds for server to start: .Use of uninitialized value in subroutine entry at /usr/local/lib/perl5/5.10.1/i386-freebsd/ DynaLoader.pm line 91.

Right, but if you are mixing major versions of perl, you'll probably encounter issues in other places. mod_perl may be the first place you are seeing this. Think of it this way - would you try this same install procedure with 5.6 and 5.8? Maybe 5.8 and 5.10 work together seamlessly, but I would look to that as a likely source of problems. ack is App::Ack, available from CPAN. I've pulled down 5.10.1 but haven't had time to do a build yet. When I do, I'm going to install 5.10.1 a separate location from my 5.8 libraries. Maybe it can integrate with 5.8 (the perl 5 porters are a very talented crew), but discovering an edge case is not something on my todo list :) I like to keep my mod_perl setup using a different perl build than the system perl. That way, I won't hose my system if I want to try some new build options for my mod_perl based perl install.

And any module can specify the oldest version of perl (or other modules on which it depends) that it will work with. I always maintain my perl modules with -MCPAN's r command, and upgrade those for which new versions are available on a regular basis. I don't know the command 'ack' that you used in your work below, but it looks like it examined source files in a subdirectory of your home directory (~). Do you have a perl5.10.1 binary that you have used in conjunction with mod_perl2? If so, can you please cd to the directory that contains that binary (/usr/local/bin?) and enter a grep command like I used: grep Perl_pad_sv perl5* and see if your 5.10.1 binary contains the symbol? And if so, how did your binary come to be?

And it has always worked, with the single exception of building mod_perl2 this time. All of the perl scripts and modules on my site work well under the new 5.10.1. I don't know enough here to say one way or the other about this, but you're mixing major versions of perl (5.10 vs 5.8) The Perl 5 Porters would be a good place for these issues. But you are seeing unresolved symbol errors when trying to use different major versions of Perl. That is enough circumstantial evidence that if I were in your shoes, I'd use a separate 5.10 install. But p5p could probably give a more educated analysis of this. Aside from the pain of re-downloading all kinds of modules as they prove to be needed over the next year or so, I know there are items in the 5.8.7 libraries from my Internet Hosting Provider, that are needed to run software from the IHP. I can certainly build a 5.10.1 without the otherlibs, and locate it somewhere else than in /usr/local/bin. Will that process completely replace all of: /usr/local/lib/perl5/5.10.1/i386-freebsd /usr/local/lib/perl5/5.10.1 /usr/local/lib/perl5/site_perl/5.10.1/i386-freebsd /usr/local/lib/perl5/site_perl/5.10.1 ?? If so, I suppose could copy them somewhere before the build, and copy them back after the build. In "Non-Boolean Build Options" on http://perl.apache.org/docs/2.0/user/install/install.html, I don't see a command to tell the mod_perl build process to use a particular perl.

The long story is at http://www.animalhead.com/CloseKeepAlive.html Interesting. But, is there really a probem to solve here? Is the point here to free up mod_perl processes faster so that they can handle other connections? Does that really have anything to do with better performace in serving up pages? Yes that's the point, but I would substitute 'apache processes' for 'mod_perl processes'. My site's front page preloads sixty-some jpg thumbnails. Years ago it was evident that KeepAlive On was needed to allow this to complete in a reasonable length of time. e.g., on a 1.5M ADSL line it takes 2-3 seconds with KA on, 6-8 seconds with KA off. So it seems that connection establishment and process dispatch take a while. Even though the Javascript that does the preloading on my front page only requests 3 images ahead of download completion, the response shown to a quick user clicking on a link is noticeably degraded by the preload stream. So you want to get the preloading over with before most users will click on a link. I decided to write this module about a year ago, when I read an article that the latest Firefoxes would open up to 6 connections to download supporting files, and that the MSIE team was considering leapfrogging them to 8. With my cheapskate ISP plan limiting the total number of processes, hanging 6 or 8 of them at a time (with a plain KeepAlive On) was a pretty scary idea. I don't think you can look at file extensions and determine when to close the connection. Can you count on how the browser will send requests? Maybe not strictly, but in general browsers request files in the order they are requested in the .html file. In the case of a lot of .jpg's the browser may take their relative file sizes into account. For example, javascript probably should be loaded last in the HTML file. Javascript that is involved in building the pages wants to get called out as early in the header as possible, either before or after the css. JavaScript that only interacts with the user could come last, but by doing that you take the chance of responding badly to a "quick" user. Then the bulk of images are often loaded via css. Are you scanning the css, too? The scanning script that accompanies the module could easily do this. I will count your email as a first request for that feature, and if I get 2 or 3 I'll add it. If that happens, can I count on you for a sample of a .css that loads images? What if you have multiple servers? Connections will be on different machines. Clearly that's a different environment than CloseKeepAlive is designed for. If customizing the keep alive is that critical then I think it's time to look at other techniques. Use a balancer and let it decided how to manage the connections (perlbal keeps the connection open forever). Anything that keeps a connection open forever is going to end up with a lot of connections? Use sprite sheets to reduce the number of required connections. I looked up "sprite sheets" and they seem to be graphics that include lots of little tiled figures used in video games. How does a browser know to split them up into separate images that pages can then call out individually? Use a CDN and cache static content forever -- and rarely hit your serve. In the end, each "page view" should only be one request to your mod_perl server anyway. My site uses all defined headers to encourage proxies and browsers to cache files. The performance of a site is the cross-product of all of the things that it does to improve performance. But you can't just look at it from the server's point of view. CKA is motivated by a desire to give the best possible performance/ responsiveness at the browser, that's consistent with keeping the load on the server reasonable.

This is good information, thank you! I have no idea what EU::MM is. Candy from Europe? 2. where the DB that the app builds should go That's probably something your application should allow to be specified, either a command line option to the script or an option to the module, or both. My plan was to run the script the first time under Build.PL, to verify that it succeeds and because without the DB there can be no testing. In which case, asking the user where to put the DB, and propagating the answer to the script source and the module source, seems to me like the easiest course for everyone. This kind of prompt is not evil, in that the automated testers can be handled by giving the query a default, maybe '/tmp'. How can such necessary things be determined, other than by asking the user? If it's a run time option (and can be changed or multiple programs can use this and thus want different values) don't ask for it at install time. It's not a run time option. The subject is a mod_perl2 script, that can only be used within the Apache2 server. I can't conceive why the DB name would ever change, and multiple programs won't use the module. I was just going to add a note before or after these two queries, that if they have a mod_perl2 library and want the module to go there, they should "do this". Putting extra docs in your module is ok, but I personally wouldn't repeat the docs that are already out there. I personally regard "docs already out there" as things that should be restated "in here" whenever the user can profit from them. As I just wrote to Perrin off-list, since only a tiny fraction of CPAN downloads are mod_perl2 modules, no one can configure CPAN for a mod_perl2 library. All perl libraries should go in the same place IMO. Whether it's Apache specific, or GTK or something else. I don't want to have to mess with @INC just because someone put something someplace non- standard. It seems that you and Perrin are in the same boat, which has "One Perl Library For All" painted on it. I am in a different boat with the authors of various mod_perl books. I set up my site under the guidance of "Practical mod_perl" p. 34: "Now you have to select a directory where all the mod_perl scripts and modules will be placed. We usually create a directory called modperl under our home directory for this purpose (e.g., /home/stas/modperl), but it is also common to create a directory called perl under your Apache server root, such as /usr/local/apache/perl." (It's /usr/local/apache2/plib on my site.) This theme is echoed on p. 58 of the "mod_perl2 User's Guide": "You often need to adjust the contents of @INC before the server starts, usually to give the server additional places to look for your mod_perl code. There are several ways to do this: • startup.pl In the startup file you can use the lib pragma like so: use lib qw(/home/httpd/projectl/lib/tmp/lib); use lib qw(/home/httpd/project2/lib); • httpd.conf In httpd.conf you can use the PerlSwitches directive to pass arguments to Perl as you do from the command line. PerlSwitches -I/home/httpd/projectl/lib -I/tmp/lib PerlSwitches -I/home/httpd/project2/lib" And on p. 61 of the "mod_perl Developer's Cookbook": "For a similar option, configure your startup.pl as use lib qw(/home/www/lib); ... By default, mod_perl adds two directories to @INC: ServerRoot/ and ServerRoot/lib/perl/, where ServerRoot is the value of the ServerRoot directive. ... If you are using a startup.pl to preload your modules, you will probably need to take advantage of the use lib syntax." Given all this, I blithely talk about "the mod_perl library" as if it's a standard part of every mod_perl site, and you and Perrin regard me as someone from another planet. Which is actually true, but that's another story. So now if Makefile.PL doesn't find 'mm' in /usr/local/lib, it prompts the user to enter the path to 'mm', which is then passed to Devel::CheckLib. The query is accompanied by a note showing the URL from which 'mm' can be downloaded. Personally, I'd just bomb out if you can't find the lib (and Devel::CheckLib is good for that). Give the user a message that you can't find the library and then exit. I doubt that someone who has a library that's not in the system libs will know where it is, and if they do they can just as easily set LD_LIBRARY_PATH themselves. This happens to me fairly reg

As I just wrote to Perrin off-list, since only a tiny fraction of CPAN downloads are mod_perl2 modules, no one can configure CPAN for a mod_perl2 library. Perhaps my attitude toward installation dialogs has been warped by recent experience with my previous CPAN module IPC::MMA. The install for version 0.54 contained no prompts. Its results came out 75% unknown, because few test environments included a necessary C library 'mm'. One of the chief testers suggested I should add Devel::CheckLib to Makefile.PL. So now if Makefile.PL doesn't find 'mm' in /usr/local/lib, it prompts the user to enter the path to 'mm', which is then passed to Devel::CheckLib. The query is accompanied by a note showing the URL from which 'mm' can be downloaded. On the other hand, my latest version 0.58 has only been tested by one tester, a week after uploading it. Maybe that's because of the new query in Makefile.PL!

RFC: Apache2::CloseKeepAlive
I'm working toward contributing a module with this working title to CPAN, and would like your comments and advice. The short story is that it's a mod_perl2 mechanism for optimizing the KeepAlive option in the Apache2 server. The long story is at http://www.animalhead.com/CloseKeepAlive.html I'm tentatively convinced it's worth contributing, but you're welcome to tell me why it's not. For sure, your advice on how to improve it will be very welcome. Specifically: • What CPAN module(s) is (are) most like this one, to use as model(s) for how to package, test, and install it? • The plan is to use Module::Build and Apache::Test. What else or something different? • Is something as specialized as this worth including in the GP Perl libraries? Or is it better to just ask where the mod_perl2 library is? • Is inclusion in the GP Perl libraries a prerequisite or assumption of Module::Build or of CPAN? In addition to where to put the module itself, it needs a place to put a companion DB-building app and a place for the resulting DB. These are not standard features of a module installation. Probably I just ask the user where they should go? If so, how do I use the answers? Thanks for being there, cmac
What can a child_init do?
Is there anything a mod_perl2 child_init phase can do to call attention to a problem? I moved a block of code from a post_config handler to a new child_init handler, without thinking much about the niceties of the move. The code contained a couple of 'die' statements, which I trust would prevent an Apache startup if executed in a post config handler. Q1: WOULD 'DIE' IN A POST_CONFIG HANDLER ABORT AN APACHE2 STARTUP? In the child_init handler, an executed 'die' did nothing noticeable. Specifically the message did not end up in the error_log. In the mod_perl2 doc pages, child_init is described as being 'of type void', which another page says means that the return value doesn't matter. I will change the 'die' to a '$s->log_error', and return the nastiest- sounding Apache return code I can find, in hopes that some future Apache might notice it. Q2: IS THERE ANYTHING A CHILD_INIT PHASE CAN DO TO ABORT ITS CHILD PROCESS, AND THUS CALL ATTENTION TO A SERIOUS PROBLEM? It's amusing that the 'child_init' process seems to be an orphan in the Apache2 world... Thanks in advance, cmac www.animalhead.com

Re: Initializing Sleepycat::DbXml (Berkeley, Oracle) objects in startup.pl
This is my first time replying to the list. I've seen advice about not being able to share a filehandle opened in a pre-fork stage before, but have two counter-examples: 1) I opened a log file for write/append in the open-logs stage of a module, and was able to (flock and) write to it in child processes. (It's called the open-logs stage!) 2) My web site ties its read-only DBs at the post-config stage and reads them in the child httpd's. My one RW DB (for guestbook filtering) has an accompanying lockfile that's opened and flocked before the DB is tied, on the fly. I have a vague recollection of reading about the circumstances in which filehandles can be inherited, but can't remember where. Programming Perl? Sorry to make things more complex, but I'll be happy if someone can clarify this. cmac www.animalhead.com On Jan 14, 2009, at 8:18 AM, Mark Hedges wrote: On Wed, 14 Jan 2009, Michael Ludwig wrote: I want to build a mod_perl2 application using Sleepycat::DbXml.

Currently, I'm trying to set up things in startup.pl (loaded via PerlPostConfigRequire), store the database environment handle in a global package variable, and access that from the PerlContentHandler. This probably won't work since the filehandle cannot be shared among mod_perl children. Your startup.pl script is running before the root apache process forks into the child processes. Scalars, lists and hashes will be cloned, but file handles won't, they have to be opened. Probably what you're thinking of is a PerlChildInitHandler so that each mod_perl child process does your connection for you when the child process first forks.
problem porting to threaded mode
Trying to shift our largely mod_perl2 web site to an Apache2 threaded
MPM and perl ithreads.
The following works under the non-threaded prefork MPM:
use DB_File;
my @dbs; # array of hash references
my @dbModTime; # mod times of db files
my @dbfns; # array of database pathnames
# executed before fork into child processes
sub post_config {
my $db;
my $s = $_[3];
# tie the DBs and get their mod times
for ($db = 0; $db < @dbfn; $db++) {
$dbs[$db] = {};
tie %{$dbs[$db]}, "DB_File", $dbfn[$db], O_RDONLY
or die ((caller 0)[3]. " can't tie " . $dbfn[$db] . ": $!");
$dbModTime[$db] = (CORE::stat($dbfn[$db]))[9]
or die ((caller 0)[3]. " can't stat " . $dbfn[$db] . ": $!");
} }
The routines that use the databases re-stat the DB files and untie and
re-tie a DB
that has changed. Each child process must do this for itself.
In the threaded environment, any thread within a process may discover
that such
an untie and re-tie is necessary, but such an operation should be
effective
for the other threads in the process as well. This means that @dbs and
@dbModTime should be shared among the threads:
use threads;
use threads::shared;
my @dbs :shared; # array of hash references
my @dbModTime :shared; # mod times of db files
Making only the changes above makes perl complain "Invalid value for
shared scalar"
about the '$dbs[$db] = {};' line. This error message can be fixed as
follows:
for ($db = 0; $db < @dbfn; $db++) {
$dbs[$db] = shared_clone({});
tie %{$dbs[$db]}, "DB_File", $dbfn[$db], O_RDONLY
or die ((caller 0)[3]. " can't tie " . $dbfn[$db] . ": $!");
$dbModTime[$db] = (CORE::stat($dbfn[$db]))[9]
or die ((caller 0)[3]. " can't stat " . $dbfn[$db] . ": $!");
$s->log->notice ($dbfn[$db]." has " .scalar(keys(%{$dbs[$db]}))."
entries");
}
Unfortunately, when this is done the server starts, but the DBs look
empty and
the log notices for each DB show "0 entries".
Removing the ':shared' tag for @dbs and the 'shared_clone()' wrapper
for '{}'
causes the log notices to show the proper number of entries for each DB,
but blows up the Apache configuration process (before the 'resuming
normal
operations' message) with
httpd in free(): error: chunk is already free
in error_log and the following on the terminal:
Abort trap (core dumped)
Error invoking apachectl start command
I guess not having databases is better. I've tried using @dbs as an
array of
references to named, shared hashes: also no database content. The
'worker'
and 'event' MPMs work identically w/r/t this problem.
Suggestions of things to try will be very welcome.
Happy New Year, cmac
Info about mp2 and threaded MPMs
I'm about to try a threaded MPM for my largely mod_perl2-based web site. Maybe my search skills are going downhill, but I haven't found much material about how to modify my scripts for the threaded environment. The first step is done, namely to minimize use of global variables. I'm pretty sure that the few that remain need to be marked as "shared" and in some cases need to have mutual exclusion zones around their use. It's confusing that Apache2 and perl5.8 have separate mutual-exclusion mechanisms. For no good reason my instinct is to use the Apache2 mutexes. Comments on the mutual exclusion alternatives will be welcome, as will suggestions for printed or online books, tutorials, and other words about threading and mod_perl2. Thanks and HNY, cmac www.animalhead.com
Re: [mp2] undefined symbol in make test with threaded Apache 2.2.11 RESOLVED
Dropped back in configuration and component programs to a working combination, then advanced in smaller steps than I had done before. You were correct, Mr G, in your prediction that the lib tree was involved. The 'Undefined symbol "PL_markstack_ptr"' in the mod_perl2 'make test' step: 1. appeared as soon as an option was added that changed the names of the "architecturally dependent" lib directories, and 2. went away when I removed the three old architecturally-dependent directories that I had tried to preserve, from the "colon separated list of additional lib directories". As a general statement of this, I would nominate: "when changing Perl build options that change the names of architecturally-dependent lib directories, don't try to keep old arch-dependent directories in @INC". With the note that such dependent directories contain hyphenated elements like 'i386-freebsd'. Thanks for your help, cmac On Dec 27, 2008, at 11:44 PM, Philip M. Gollucci wrote: Philip M.

The page on the mod_perl site about "what to do before submitting a problem report" suggested trying the current build from the location I used, as a data point for the overall report. So I complied with those instructions.

It has been years since I compiled or assembled anything by hand, but I do go back in the software field to 1963, when such things were sometimes still done. All of several set of instructions I have read, as to how to build mod-perl, have recommended the apxs method. > > > *** /usr/local/bin/perl -V > > Summary of my perl5 (revision 5 version 8 subversion 9) configuration: > So this isn't in the ports tree yet, so you also compiled perl by hand I have never had anything to do with the ports facility, and have built all of our site's software from source for years. The build sequences used for Aapche 2.2.11, perl 5.8.9, and mod-perl 2.0.4 have all been used on previous occasions with full success. The big change is building 2.2.11 for the event MPM. > > > @INC: > > /usr/local/lib/perl5/site_perl/5.8.9 > > /usr/local/lib/perl5/site_perl/5.8.8 > > /usr/local/lib/perl5/site_perl/5.8.7 > > /usr/local/lib/perl5/vendor_perl/5.8.9 > > /usr/local/lib/perl5/vendor_perl/5.8.7 > Looks like your perl tree has some history, I'd try with a clean tree .. my > money is here. The Perl5.8.9 in question has worked very well with the previous prefork Apache 2.2.10 and a mod-perl built against it. A "clean tree" approach is complicated by the fact the tree has essential modules in it from my internet hosting provider (IHP), mostly in the vendor-perl branch but perhaps in other branches as well. > > > *** Packages of interest status: > > mod_perl : 1.29 > > mod_perl2 : 2.03, 2.05 > Speaking of clean trees, that can't be good. > you have multiple versions of mod_perl2 installed which almost certainly means > that you'll get a mix match between .pm and .so files.

This has never caused any problems in the past. (httpd.conf calls out the 2.0.4.so.) But on your advice I will rename the 2.0.3 with an extra ".hide" after the ".so", and retry the thing as soon as I get back to my development machine next Monday. FWIW I'm startled by the "2.05" but I assume that's because the last thing built was the _20081223052020 on the recommendations of the mod_perl web site. > > FWIW, you really shouldn't install your own perl into /usr/local/bin/perl on > FreeBSD you should put yours somewhere else. > There is great value to me in having a single perl that is used for all applications, rather than a "my perl" and "their perl" and "the perl used by that other gang over there".

Re: [mp2] undefined symbol in make test with threaded Apache 2.2.11
As Adam Prime notes, 5.8.9 became the current stable Perl recently. It is the other new ingredient besides Apache 2.2.11. I don't normally introduce so many new things at once, but happen to be working through a new sandbox/developmental version of our website. One of the Apache developers suggested I should wait for 5.10.1, so that's why I'm futzing with 5.8.9. I don't know why the bug-report- generating script would lie to us about what Perl I'm using. Oooh your os? Was that your machine doing something bad as you were typing? I won't be doing development for most of a week, but if you have any other questions, I'll be monitoring email. Is there anything else I should "get through" so that you will take a deeper look at this? If so please advise. Happy Holidays, cmac On Dec 22, 2008, at 11:25 PM, Philip M.

content_type in SSI- or directly-called mp2 scripts
My mod_perl2 scripts mostly fall into 2 categories:
1) scripts that are called by URL location, and generate complete
content-pages
2) scripts that are called by SSI "include virtual" sequences
in .html files, and generate part of a page
In some cases scripts of type 1 directly call scripts of type 2 to
generate parts of their pages.
(Call this "case 3").
My questions are about when to call $r->content_type('text/html')
Such a call is a good idea in category 1, right?
Such a call probably should not be made by the directly-called script
in case 3, right?
Apache probably can't even tell that a new script has gotten into the
act, the calling
and called script are both in the undifferentiated sea of mod-perl
code, right?
In an SSI-invoked script (category 2) is a content_type call a)
required, b) good practice,
or c) a bad idea?
Thanks,

--- also, in the subsequent 'sudo make install', every module was
tagged with:
Use of uninitialized value in length at /usr/local/lib/perl5/5.8.8/

So I changed said line 134 from
if (length $options{perm_rw}) {

So of course the response to the form submission took several minutes. I will pursue this difference with my ISP and the author of the package. Sorry to have bothered the list about such a thing...

Apache2::Request does not foul up content length
On further investigation, there is no problem between Apache2::Request and KeepAlive, as I had previously accused. The problem was that the checking routines, after form data was obtained from Apache2::Request, included a Perl module called Mail::CheckUser. This module performed various transactions on the Internet, to check the authenticity of an email address submitted in the form. These Mail::CheckUser calls work fine under Apache1 and mod_perl(1). When the Mail::CheckUser calls are commented out under Apache2 and mod_perl2, our handler performs correctly. Can anyone suggest a way (possibly including an external process initiated by the subject mod_perl2 handler) by which this mod_perl handler can: 1. use the lengthy checking performed by Mail::CheckUser, and 2. allow the Apache2 server to maintain KeepAlive??? Thanks, Craig MacKenna www.animalhead.com
Re: Apache2::Request fouls up content length?
Jonathan, thank you for your replies! The client I'm testing with is, in most contexts, not "slow". It's a dual-processor 1.25 MHz PowerMac on a DSL line, with the Safari browser which does most things faster than any other PC or Mac browser I've used. Thought I had a solution: since my two pages containing forms are both under SSL, I put "KeepAlive On" in the virtual host for 80, and "KeepAlive Off" in the virtual host for 443. Unfortunately this did not fix the problem, from an SSL page. Apache::Request worked with KeepAlive under Apache 1 and mod_perl 1. So I feel like things have gone backward... My front page downloads a series of 80+ small jpg's, and the impact of a general KeepAlive Off on that operation is unacceptable. The complexity of a "multi-server / multi-apache setup" is more than I want to deal with. I much prefer KeepAlive on a single Apache to using Apache2::Request on a multi-server solution. It's easy enough to get the form data and parse it myself. 1. Do you think the problem is in mod_perl or apreq2? 2. Does that module have a bug reporting system (other than this mailing list) ? 3. Is there a known bug for Apache2::Request vs. KeepAlive? 4. If not, where can I post one, so this can be fixed for other people?

Thanks much, Craig MacKenna www.animalhead.com personally, I would suggest this: forget about keepalive in modperl don't run mod_perl on port 80. run a proxy on it -- either apache or something lightweight like nginx run your app on port 80xx using its own apache. have keepalive turned off. keepalive can be turn on in your port 80 dae,pm serve static off the proxy, only hit up mp for dynamic content. its not as fast as if you had keepalive on the proxied connection, but its still considerably faster than not-proxying , and you don't deal with any of the issues of a slow-client tying up your modperl process there's a section in the modperl book explaining the multi-server / multi-apache setup in depth. its online, via google // Jonathan Vanasco | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | FindMeOn.com - The cure for Multiple Web Personality Disorder | Web Identity Management and 3D Social Networking | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | RoadSound.com - Tools For Bands, Stuff For Fans | Collaborative Online Management And Syndication Tools | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Apache2::Request fouls up content length?
I'm still hoping for a good answer on my previous build problem. But for now I'm proceeding with testing using the mod_perl that my hosting provider set up. The first script that I've tested that uses Apache2::Request gives a problem. The browser sits and waits for its timeout period, then the complete expected response is available. My limited experience suggests this is probably because the response's content-length value is fouled up (or the header isn't sent?). My "server signature" is Apache/2.2.3 (Unix) mod_ssl/2.2.3 OpenSSL/0.9.7e-p1 mod_apreq2-20051231/2.5.7 mod_perl/2.0.2 Perl/v5.8.7 Server at mackenna1.securesites.net OS is FreeBSD 6. The problem happens under both http: and https:. mod_deflate and mod_include are also active for the transaction. Anyone can see the problem at http://mackenna1.securesites.net/contact.html which is the site's contact form. If you just hit "send" without entering anything, you'll get a response that says you didn't enter anything, but it will take a long time. Apache2::Request had bigger problems until I included the following line in httpd.conf: LoadModule apreq_module modules/mod_apreq2.so That .so was also provided by my hosting provider (Verio). Does this sound familiar? Could it be avoided by newer versions of any of the software? Craig MacKenna Los Gatos, CA

Code Serialization and mod_perl
Hello, Please help me understand how Perl with mod_perl handles the following situation. Consider 2 clients out in the WWW using the same form to work on 2 different records of the same type. At submission, the form executes a database function and passes the data entered using the form. The function retrieves the data from the CGI-like connection, assigns the data to Perl dataspaces and begins processing the code series of the function. Now the 2nd client executes the function in the same way, right on the heels of the 1st client. In the C language in a network environment, when a client calls a database function in a DLL to access a server database, a system semaphore is is used to serialize code access to prevent the corruption ofdataspaces. With only Perl, a different Perl interpreter instance is started for each CGI request. The instances don't know about each other and dataspaces are unique to an instance. How does Perl with mod_perl handle this. Are there any important differences with the only Perl situation. Might the dataspaces be corrupted? How does this work? My technical environment is Windows XP Home, Apache 2.0.049, Perl 5.8.3, and mod_perl 2.0.2. Thank you in advance for any responses. I appreciate your time.

Outgoing content-length apparently 0
Hope this is the address to which to send a problem/question!
Our Verio "Virtual Private Server" is FreeBSD-based with Apache 1.3.33.
I've installed mod-perl 1.29 and mod_gzip 1.3.19.2a, and revised our former
CGI scripts to run as perl modules under the Apache API.
They are operating fine, except for one residual problem.
When a script builds a response, mod_gzip squawks in the error_log like
this:
... [error] mod_gzip: EMPTY FILE [/tmp/_16777_106_7.wrk] in sendfile2
... [error] mod_gzip: Make sure all named directories exist and have ...
The corresponding entry in access_log looks like this:
... "POST /contact HTTP/1.1" 200 0or
... "GET /x/whoami.cgi HTTP/1.1" 200 0
The zero outgoing length in the log entry agrees with mod_gzip's complaint,
but in reality the correct body is going out to the browser (I was the
browser user for both of the access_log cases above). The former case
(contact) runs under mod_perl, while the latter runs under mod_cgi.
Today I tried an approach to solving this, wherein I build up the whole body
in a scalar $body, and then do a
send_response('text/html');
where send_response is:
sub send_response {
$r->header_out("Content-Length", length $body);
$r->send_http_header(shift);
if (!$r->header_only) {$r->print($body)}
undef $body;
}
The problem still persists. So I searched our logs. The first "200 0" log
entry for a script was seen before I installed mod_gzip, and after I
followed the advice of the "Practical mod-perl" book, and moved all of the
scripts from /usr/local/apache/cgi-bin to a new directory
/usr/local/apache/perl. Before that the scripts had been running fairly
correctly under mod_perl and Apache::Registry in .../cgi-bin, without
showing any "200 0" log entries for scripts.
None of the following changes in httpd.conf seem to affect the problem:
PerlSendHeaders On/Off
PerlSetupEnv On/Off
Option +ExecCGI in the Location block of a script
Finally I tried making a block in an attempt
to get as close to the conditions under which the last script output with a
non-zero length was seen. No help!
Scripts that do a redirect using the same send_response routine as above,
show log entries like "302 771", although $body contained just a few bytes.
So my question is: what do I need to do, to make Apache hand off the output
from the script to mod_gzip properly, and (far less important) show the
proper length in the log?
Thanks to anyone who can help,

Re: Can't locate ../Functions/db.pl in @INC
I'll give this a shot, seeing as no one seemed to have answered: In your pl files you can try including something like: use lib qw(directory containing module directories); Example: use lib qw(/usr/local/apache2/perl); In my config I have PerlRequire /usr/local/apache2/perl/startup.pl which contains: use lib qw(/usr/local/apache2/perl); 1; Not sure if this will work with your version of apache.

RE: Win32 build problems libapreq2-2.04_03-dev
After updating both Apache2 and mod_perl on the W2K Server, there are still
some problems in building libarpeq2-2.04_03-dev on Win32.
Current software levels are:
Apache/2.0.50 (Win32) mod_perl/1.99_16 Perl/v5.8.4 Server
When invoking 'nmake perl_glue', 'nmake perl_test', or nmake perl_install
each will return the same error message. Nmake correctly detects that
Apache2 is installed at 'E:\Apache2'.
.

st) at E:/Perl/site/lib/Apache2/Apache/Build.pm line 1715.
NMAKE : fatal error U1077: 'E:\Perl\bin\perl.exe' : return code '0x2'
If this error message is indeed attempting to find files in the directory,
'D:\Apache2\include', it won't because the directory doesn't exist. Its not
clear to me where the build process is picking up the reference to
'D:\Apache2\include'.
Scanning both the directories 'E:\Perl' and 'E:\Apache2' for 'D:\Apache2',
the file
'E:\Perl\site\lib\Apache2\auto\libaprext\extralibs.ld' was found to contain
references to 'D:\Apache2\lib'. After correcting the invalid references, the
problem still exists.
Windows XP Pro is having the exact same problem too.

RE: Apache::DB ported to mp2
Frank, I get the same error exact error with Apache::DB 0.06. Compress-Zlib-1.33 has compiled & installed successfully just now and it appears to be using XS. VS .Net (prior version) is generating the same error too. Note: The option '-Gf' was changed to '-GF' in the makefile because the compiler didn't like '-Gf'.

I'm new to this so maybe what I'm about to say is incorrect. If so please attempt to correct me if possible. Is it possible for me to select which version of perl I use when building modperl? If so how would I do that? Could I do this via the makefile? Also I'm not attempting to install a binary version of modperl I've downloaded the apache and modperl tar files and was attempting to build it myself.
