Hi all,
I remember at OSCON 2005 there was talk of adding DTrace probes
to PHP (in fact, I have a photo of Bryan and Wes working on it!).
Did they ever get into the upstream branch, ''cause I don''t
recall
seeing a --enable-dtrace (or similar) configuration option when
I recently built PHP 5.2.1. If not, is there an ETA?
TIA,
--

Hi Rich: This has been implemented as a PEAR module. You need to # pear install dtrace or # pecl install dtrace then add extension=dtrace.so? to the php.ini file See Wez Furlong''s blog http://netevil.org/node.php?uuid=42f82a8b-09b7-5013-1667-2f82a8b24ead and Bryan''s blog. http://blogs.sun.com/bmc/entry/dtrace_and_php_demonstrated For more details. -Angelo Rich Teer wrote:> Hi all, > > I remember at OSCON 2005 there was talk of adding DTrace probes > to PHP (in fact, I have a photo of Bryan and Wes working on it!). > Did they ever get into the upstream branch, ''cause I don''t recall > seeing a --enable-dtrace (or similar) configuration option when > I recently built PHP 5.2.1.

Hi Angelo, since which PHP version is the extension included ? przemol On Wed, Mar 07, 2007 at 02:23:45PM -0500, Angelo Rajadurai wrote:> Hi Rich: > > This has been implemented as a PEAR module. > > You need to > # pear install dtrace > or > # pecl install dtrace > then add > extension=dtrace.so? > to the php.ini file > > See > Wez Furlong''s blog > > http://netevil.org/node.php?uuid=42f82a8b-09b7-5013-1667-2f82a8b24ead > > and Bryan''s blog. > http://blogs.sun.com/bmc/entry/dtrace_and_php_demonstrated > > For more details. > > -Angelo > > Rich Teer wrote: > >Hi all, > > > >I remember at OSCON 2005 there was talk of adding DTrace probes > >to PHP (in fact, I have a photo of Bryan and Wes working on it!). > >Did they ever get into the upstream branch, ''cause I don''t recall > >seeing a --enable-dtrace (or similar) configuration option when > >I recently built PHP 5.2.1.

Hi Przemol: Not sure what versions are supported. The module was developed way back in Aug of 2005 so I''m pretty sure the support would go back. Just note that this is not "included" in PHP It is implemented as a ZEND extension. So you need to follow the steps I outlined below. -Angelo przemolicc at poczta.fm wrote:> Hi Angelo, > > since which PHP version is the extension included ? > > przemol > > On Wed, Mar 07, 2007 at 02:23:45PM -0500, Angelo Rajadurai wrote: > >> Hi Rich: >> >> This has been implemented as a PEAR module. >> >> You need to >> # pear install dtrace >> or >> # pecl install dtrace >> then add >> extension=dtrace.so? >> to the php.ini file >> >> See >> Wez Furlong''s blog >> >> http://netevil.org/node.php?uuid=42f82a8b-09b7-5013-1667-2f82a8b24ead >> >> and Bryan''s blog. >> http://blogs.sun.com/bmc/entry/dtrace_and_php_demonstrated >> >> For more details. >> >> -Angelo >> >> Rich Teer wrote: >> >>> Hi all, >>> >>> I remember at OSCON 2005 there was talk of adding DTrace probes >>> to PHP (in fact, I have a photo of Bryan and Wes working on it!). >>> Did they ever get into the upstream branch, ''cause I don''t recall >>> seeing a --enable-dtrace (or similar) configuration option when >>> I recently built PHP 5.2.1.

[looks like my other email address can''t send to this list, so resending from one that probably can] I believe that Bryan was looking at making some dtrace changes to facilitate bridging the C and PHP level call stacks so that a more true and complete overview of the actual call stack. I think we both got busy and distracted with other projects though, so I don''t know the status of that. He kept telling me that there were some really ugly parts to it, so I had to content myself with copy-n-paste of the output from Bryan''s gnome-terminal. :) The dtrace implementation for php is as an installable module so that it can be retroactively fitted into PHP 4 (we don''t typically add new things to stable branches). The module approach introduces a little bit of overhead; if there is strong demand I can lobby for putting the probes into the core. I''ve had 2 people report issues getting the probes to be visible; I don''t know those 2 represent 100% of the people that have tried to use it (PHP + Solaris isn''t the most popular combination, judging by bug reports at bugs.php.net), so I''m interested to hear if you experience issues with it. --Wez.

Technically, it''s not a zend extension, it''s a php extension. I''ve already explain why this is in previous emails, perhaps they are all being filtered? --Wez.
