Providers for Various Shells

Providers for Various Shells

An effort has been begun to make available DTrace providers for various shells. This page is to document these efforts and provide code diffs, tarballs and/or any other documentation.

As more providers are begun, they will be listed here.

Please see this link for why we did /bin/sh first, rather then barraging Alan and Brendan with Email.

Bourne Shell

Owner: alanh (Alan Hargreaves)

Status: alpha

I've just uploaded a SPARC binary and made some major changes (see below). The code is still experimental, be careful replacing /usr/bin/sh with this, you might want to place it in a different directory for experimentation.

There were originally some problems applying the diffs with gpatch, Let me know if you have any. If all else fails I can make a tarball of the modified files available.

Notes

Aug 20

Fixed command-entry to only fire in the parent shell.

Aug 14

There were two major changes to the provider:

1. exec has been renamed to command.
2. script-begin and script-end have become script-start and script-done respectively.

These changes are reflected in the documentation.
