-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2010-9923 2010-06-14 16:42:52 --------------------------------------------------------------------------------
Name : python-foolscap Product : Fedora 13 Version : 0.5.1 Release : 1.fc13 URL : http://foolscap.lothar.com Summary : Next-generation RPC protocol, intended to replace Perspective Broker Description : Foolscap (aka newpb) is a new version of Twisted's native RPC protocol, known as 'Perspective Broker'. This allows an object in one process to be used by code in a distant process. This module provides data marshaling, a remote object reference system, and a capability-based security model. -------------------------------------------------------------------------------- Update Information: Changes since the last version: * Release 0.5.1 (25 Mar 2010) ** Bugfixes This release fixes a significant performance problem, causing receivers a very long time (over 10 seconds) to process large (>10MB) messages, for example when receiving a large string in method arguments. Receiver CPU time was quadratic in the size of the message. (#149) ** Other Changes This release removes some unused code involved in the now-abandoned resource-exhaustion defenses. (#127) * Release 0.5.0 (18 Jan 2010) ** Compatibility The wire format remains the same as in earlier releases. The preferred API import path has changed, see below. ** API changes: import statements, foolscap.api To reduce circular dependencies in Foolscap's internal code, a new "foolscap.api" module has been created. Applications should use: from foolscap.api import Tub instead of e.g. "from foolscap import Tub". Deprecation warnings will be raised for code which imports symbols directly from the "foolscap" module. These warnings will turn into errors in the 0.6.0 release. (see ticket #122 for details) The nearly-useless getRemoteURL_TCP() function was removed. ** setup.py is more windows-friendly The main setup.py script has been modified to use setuptools "entry_points=" on windows, which should help create runnable executables of "flogtool" and "flappserver", with proper extensions. Entry- point scripts are not used on non-windows platforms, but setuptools still creates fairly opaque executable scripts (which makes it hard to figure out that e.g. /usr/bin/flogtool wants to import the "foolscap" module). To get non- opaque scripts, install with "setup.py install --single-version-externally- managed". (#109) ** tool changes *** flappserver "flappserver create" now records the umask value from its environment, and uses it later when the server is started (since normally twistd resets the umask to a very restrictive value). A new --umask argument was added to override this. The server's base directory is chmod go-rwx to protect the private key from other users. The "flappserver start" command uses twisted.scripts.twistd.run(), instead of spawning an intermediate "twistd" process with os.execvp(). This should make things work better in environments where Twisted is not fully installed (especially on windows) and correctly launching "twistd" is non-trivial, such as when some other package is installing it as a setuptools dependency. "flappclient upload-file ~/foo.txt" will use os.path.expanduser() on the filename, even if your shell does not. This should make it easier to use from e.g. buildbot upload commands. (#134) *** logging The "flogtool dump" and "flogtool web-viewer" commands now have a --timestamps argument, which controls how timestamps are expressed (UTC vs localtime, ISO-9601, etc). The web-viewer HTML pages now have more timestamp and sorting options, and hyperlinks to select each. (#100) "flogtool web-viewer --open" will tell your local web browser to open to the correct page, using the Python stdlib "webbrowser" module. "flogtool dump" now emits a better error when told to open a missing file. *** examples Examples of running the Git version-control-system over a flappserver-based secure connection have been added to doc/examples/ . This enables remote-update authority to be expressed as a FURL with no other shell privileges. To accomplish the same with ssh "authorized_keys" command restrictions is annoying and error-prone. See doc/examples/git-proxy- flappclient for setup instructions. This will probably be simplified to a single "git-furl" executable in a later release. The xfer-client/xfer-server /command-client examples have been removed, obsoleted by the flappserver/flappclient tools. ** Other changes The DeprecationWarning for the obsolete "sets" module is now removed on python2.6 (#124) When a getReference() call fails because the remote Tub does not recognize the FURL, it now only emits the first two letters of the secret swissnum in the exception, instead of the whole thing. This reduces information leakage into e.g. stderr logs from a "flappclient --furlfile=X upload-file" command. DeadReferenceError now includes the remote tubid, interfacename, and remote method name of the message that was being sent when the lost connection was discovered, so log.err() calls which record a DeadReferenceError should include this information. This may make it easier to locate the code that provoked the error. -------------------------------------------------------------------------------- ChangeLog: * Sun Jun 13 2010 Thomas Spura <[email protected]> 0.5.1-1 - update to new version -------------------------------------------------------------------------------- References: [ 1 ] Bug #603533 - please update at least in rawhide https://bugzilla.redhat.com/show_bug.cgi?id=603533 -------------------------------------------------------------------------------- This update can be installed with the "yum" update program.
