r3774 | poeml | 2008-04-22 17:39:45 +0200 (Tue, 22 Apr 2008) | 3 lines
A first draft on implement systematic exception handling:
Add errors.py with some exceptions defined, and babysitter.py to handle them
........
r3775 | poeml | 2008-04-22 22:34:12 +0200 (Tue, 22 Apr 2008) | 9 lines
- new global options:
--debugger jump into the debugger before executing anything
--post-mortem jump into the debugger in case of errors
-t, --traceback print call trace in case of errors
- traceback and post_mortem can also be set in .oscrc.
- catch more errors (HTTPError).
- make config accessible from outside of the Osc instance, by making it a class
attribute
........
r3779 | poeml | 2008-04-23 00:55:49 +0200 (Wed, 23 Apr 2008) | 5 lines
- new global option:
-d, --debug print info useful for debugging
- catch some more errors (HTTPError), with OscHTTPError which isn't very
advanced yet.
........
r3781 | Marcus_H | 2008-04-23 01:02:00 +0200 (Wed, 23 Apr 2008) | 2 lines
- added OscConfigError class (just for testing).
- small change in the signature of the OscBaseError constructor (actually we should get rid of the 'args' tuple because it will be deprecated sooner or later
........
r3782 | Marcus_H | 2008-04-23 02:02:13 +0200 (Wed, 23 Apr 2008) | 2 lines
- access the prg.conf.config dict in a save way - this way we avoid AttributeErrors if the prg.conf.config dict doesn't exist
- in case of an configparser error we have to use the prg.options object directly (this was removed in r3781 by accident)
........
r3787 | poeml | 2008-04-23 09:23:56 +0200 (Wed, 23 Apr 2008) | 4 lines
- remove local exception handling from do_req
- for HTTPError, print details (headers and response) when in debug mode
- catch AttributeError
........
r3789 | poeml | 2008-04-23 16:23:14 +0200 (Wed, 23 Apr 2008) | 4 lines
- errors: add two new classes named OscWrongOptionsError and OscWrongArgsError
- commandline: raise instances of the new errors in a number of places
- commandline: add get_cmd_help() to Osc instance which returns the formatted help of a subcommand
........
r3790 | Marcus_H | 2008-04-23 16:48:28 +0200 (Wed, 23 Apr 2008) | 4 lines
- added 2 new exception classes: OscNoConfigfileError and OscIOError
- added new method write_config() to the conf.py module: This method writes osc's configuration file
- minor cleanups in the conf module
........
r3791 | poeml | 2008-04-23 17:11:07 +0200 (Wed, 23 Apr 2008) | 3 lines
small compatibility fix for r3790: try-except-finally isn't supported in
python-2.4.2, thus do the same as try-except inside a try-finally.
........
r3792 | poeml | 2008-04-23 17:37:53 +0200 (Wed, 23 Apr 2008) | 2 lines
fix up the remaining places regarding handling of errors related to commandline parsing

........
r3817 | poeml | 2008-04-24 20:21:32 +0200 (Thu, 24 Apr 2008) | 9 lines
- remove errors.OscHTTPError again.
it seems simpler to use urllib2.HTTPError instead (and just add a specific
error text message where appropriate, and re-raise)
- for 404s, check out _which_ part was not found
it is very ugly, but may be considered Good for pragmatic reasons
- removed local exception handling and workaround for returned 500's from
delete_package() and delete_project(), thereby getting rid of 4 possible exit
points.
........
r3818 | Marcus_H | 2008-04-24 22:36:17 +0200 (Thu, 24 Apr 2008) | 1 line
- this check is superfluous because every HTTPError instance has a code attribute
........
r3819 | poeml | 2008-04-25 00:39:39 +0200 (Fri, 25 Apr 2008) | 1 line
remove a forgotten debug line from core.delete_project()

- ditch local error handling from wipebinaries(), rebuild(), and abortbuild()
........
r3821 | poeml | 2008-04-25 10:56:38 +0200 (Fri, 25 Apr 2008) | 2 lines
It is never needed to import the exception module.
........
r3822 | poeml | 2008-04-25 11:13:39 +0200 (Fri, 25 Apr 2008) | 4 lines
- when going into the debugger with --post-mortem, always print a traceback before
(thus implying -t)
- do not jump into the debugger if not on a TTY, or working in interactive mode
........
r3827 | poeml | 2008-04-25 13:07:46 +0200 (Fri, 25 Apr 2008) | 9 lines
- add errors.OscWorkingCopyOutdated, which takes a tuple with three args:
path to working copy, current rev, expected rev
- add handler for urllib2.URLError errors to the babysitter
- simplify the OscWrongArgsError and OscWrongOptionsError handlers, by removing
the extra line "Sorry, wrong ..." that was printed before the messages given
when the error was raised.
- remove one more errors.OscHTTPError which was still there, and raise
urllib2.HTTPError instead (show_package_meta())
........
r3829 | poeml | 2008-04-25 14:19:10 +0200 (Fri, 25 Apr 2008) | 11 lines
- comment some methods in osc.core which are used by nearly all do_* methods in
osc.commandline
- improve "is not a package/project dir" error messages, by printing the
absolute path tried, instead of '.' for the cwd
- make core.store_read_package() raise a proper NoWorkingCopyError instead of
terminating
- give attribution to things in babysitter.py copied from mercurial
- prefix HTTPError exceptions with 'Server returned an error:'
- remove obsolete local error handling from do_prjresults(), do_importsrcpkg(),
do_repos()
........

catch IOError exceptions in the babysitter
........
r3837 | poeml | 2008-04-25 17:27:36 +0200 (Fri, 25 Apr 2008) | 5 lines
- do_remotebuildlog: raise errors for wrong arguments, remove exits
- raise AttributeError in make_meta_url() instead of exiting
- delete unused method core.delete_server_files()
- replace exit call inside make_meta_url() with an AttributeError
........
r3838 | poeml | 2008-04-25 17:49:18 +0200 (Fri, 25 Apr 2008) | 1 line
simplify the check in do_checkout if a project exists, by using show_project_meta() instead of meta_exists
........
r3839 | poeml | 2008-04-25 18:31:26 +0200 (Fri, 25 Apr 2008) | 6 lines
- commandline do_checkout(): change the order of the two checks, first do the
(cheaper) check for existing directory
- core.core checkout_package(): simplify the check in if the package
exists, by using show_package_meta() instead of meta_exists
Let it throw an exception, instead of using sys.exit().
........
r3841 | Marcus_H | 2008-04-27 15:48:06 +0200 (Sun, 27 Apr 2008) | 5 lines
- added 2 new exception classes: PackageError() and PackageExistsError. The PackageError() class is meant to be the base class for all subsequent package exceptions.
- get rid of 2 sys.exit(1) calls
- make the update() method of the Project() class safer: in any case we have to write the _packages file otherwise the package tracking will be screwed up.
- minor fix in delPackage(): use getTransActPath() when printing out the filename
........
r3842 | Marcus_H | 2008-04-27 16:52:55 +0200 (Sun, 27 Apr 2008) | 3 lines
- make the commit() method safe: in any case we have to write the _packages file otherwise the package tracking will be screwed up.
- removed another sys.exit(1): raise an exception if a package is missing when doing a commit. For now we use the PackageExistsError() exception but this might change in the future (updated description of PackageExistsError() according to this change)
........
r3848 | poeml | 2008-04-28 12:46:45 +0200 (Mon, 28 Apr 2008) | 3 lines
rename several error classes, dropping the "Osc" prefix, and "Error" suffix in
cases where they don't really make sense.
........
r3849 | poeml | 2008-04-28 12:57:32 +0200 (Mon, 28 Apr 2008) | 3 lines
- rename osc.errors module to osc.oscerr, to make it easier to import it from
other programs and have a crystal clear namespace
........
r3850 | poeml | 2008-04-28 13:26:12 +0200 (Mon, 28 Apr 2008) | 2 lines
split PackageExists exception class into PackageExists and PackageMissing

osc -- opensuse-commander with svn like handling Please send patches to poeml@suse.de, or work directly on https://forgesvn1.novell.com/svn/opensuse/trunk/buildservice/src/clientlib/python/osc/ INSTALLATION: RPM packages are here (yum repository): http://download.opensuse.org/repositories/openSUSE:/Tools/ To install from svn, do python setup.py build python setup.py install # create a symlink 'osc' in your path pointing to osc.py. ln -s osc-wrapper.py /usr/bin/osc Alternatively, you can directly use osc-wrapper.py from the source dir (which is easier if you develop on osc). The program needs the cElementTree python module installed. On SUSE, the respective package is called python-elementtree (before 10.2: python-xml). For local building, you will need python-urlgrabber in addition. Those are standard package on SUSE Linux since a while. If your version is too old, you can find python-elementtree and python-urlgrabber here: http://download.opensuse.org/repositories/devel:/languages:/python/ CONFIGURATION: When you use it for the first time, it will ask you for your username and password, and store it in ~/.oscrc. If authentication data is found in .netrc, it will also be used. USAGE EXAMPLES: (online at http://en.opensuse.org/Build_Service/CLI ) To list existing content on the server osc ls # list projects osc ls Apache # list packages in a project osc ls Apache subversion # list files of package of a project Check out content osc co Apache # entire project osc co Apache subversion # a package osc co Apache subversion foo # single file Update a working copy osc up osc up [pac_dir] # update a single package by its path osc up * # from within a project dir, update all packages osc up # from within a project dir, update all packages AND check out all newly added packages If an update can't be merged automatically, a file is in 'C' (conflict) state, and conflicts are marked with special <<<<<<< and >>>>>>> lines.
