repoze.debug Changes

0.7.2 (2011-04-18)

• Don’t require ‘threadframe’ module in Python >= 2.5 (thanks, Jonathan Ballet). Closes http://bugs.repoze.org/issue162.

• Don’t crash if unicode values are present in threads’ state (thanks, Jonathan Ballet). Closes http://bugs.repoze.org/issue162.

0.7.1 (2010-03-11)

• Sphinxified docs.

• Don’t compute tracelog records unless we are going to write them.

0.7 (2009/09/06)

• The iterator returned by an application was closed too soon when using the responselogger middleware, resulting in, e.g. errors from paste.fileapp complaining about “file already closed”.

• If the keep parameter in the “responselogger” middleware is set to zero, no entries are logged (not even one, as previously may have happened).

• Better test coverage.

• Ignore HTTP errors in post-mortem debug middleware. The exceptions we want to catch here are application-level. A configuration option has been added to keep the old behavior.

• Added middleware “threads” to debug threads (based on an adaptation of Florent Guillaume’s “DeadlockDebugger” product for Zope 2).

0.6.2 (2008/07/03)

• Show a “short” URL in the debug UI.

0.6.1 (2008/07/03)

• Fix debug UI bug: show escaped body regardless of content-type.

0.6 (2008/07/02)

• Fix logging bug. Symptom: AttributeError: ‘NoneType’ object has no attribute ‘info’

0.5 (2008/06/30)

• Make debug request id reflect approximate UNIX time rather than a random debug id.

• Deal with responses via a generator; don’t unwind response bodies into memory.

• Default max_bodysize is now 3K rather than the entire response body.

• User interface; keep entries around to show in GUI. See /__repoze.debug/static/debugui.html.

• We now write two logs: a verbose log, and a trace log. The verbose log contains information about headers, request information, response bodies, etc. The trace log is more compact and is written in essence to be parsed by a tool.

• The ‘filename’ option in Paste config is now ‘verbose_log’.

• Port Zope’s ‘requestprofiler’ script to WSGI. Invoke via ‘wsgirequestprofiler’ to see help; operates against ‘trace’ log.

0.4 (2008/06/25)

• Add pdbpm middleware for dropping into the post-mortem debugger upon an exception (copied from repoze.errorlog).

0.3 (2008/06/25)

• Add ‘canary’ middleware for detecting environment dictionary leaks. Add to your Paste config via ‘egg:repoze.debug#canary’; it takes no arguments. If refcounts to repoze.debug.canary.Canary grow without bound, you know you are leaking WSGI environment dictionaries.

• Add source url to response logging.

0.2 (2008/06/14)

• Add warning if content-length != body length.

0.1 (2008/06/13)

• Initial release.
