This file summarizes the major and interesting changes for each release. For a

detailled list of changes, please see ChangeLog.

2.1.2 (UNRELEASED)

------------------

Improvements:

 * Clean up module imports.

 * test/run: Run pyflakes, if available.

 * package_hook: Add --tags option. Thanks to Brian Murray.

 * launchpad.py: Drop the external multipartpost_handler.py (which is not

   portable to Python 3) and replace it with using the standard email module.

 * launchpad.py: Also work with Python 3. Deal gracefully with a missing

   "launchpadlib" module; this is not yet available for Python 3, but not

   required for client-side reporting.

Bug fixes:

 * apport-retrace: Fix crash when using the --procmaps option.

 * setup.py: Update hashbang lines of installed scripts in data directory to

   the python executable setup.py was run with, similar to what already happens

   to scripts installed to ../bin/.

2.1.1 (2012-05-30)

------------------

Improvements:

 * launchpad.py: When closing a bug as a duplicate, copy some well-known tags

   to the master bug. Thanks Brian Murray.

 * launchpad.py: Set importance of Python crash reports to "Medium" by default,

   similar to signal crashes. Thanks Brian Murray.

 * hookutils.py: Add attach_default_grub() convenience function from the grub2

   package hook so it can be used by other packages. Thanks Brian Murray.

 * launchpad.py: Make Launchpad bug subscription user/team configurable: The

   initial subscriber after filing a bug can be set with the

   "initial_subscriber" crashdb option, and the team which gets subscribed

   after retracing with "triaging_team". (LP: #980726)

Bug fixes:

 * report.py: Do not change the SourcePackage: field if the binary package is

   not installed and does not exist. This fixes source package hooks to

   actually work in some cases where source and binary package names overlap.

   (part of LP: #993810)

 * apport-gtk, apport-kde: Avoid collecting information twice in "bug update"

   mode. This caused a crash in cases where the source package in a bug report

   does not correspond to an installed binary package. (LP: #993810)

2.1 (2012-05-18)

----------------

Improvements:

 * packaging.py, install_packages(): Add permanent_rootdir flag and if set,

   only unpack newly downloaded packages. Implement it for the apt/dpkg

   backend. Thanks Evan Dandrea.

 * apport-retrace: Add --sandbox-dir option for keeping a permanent sandbox

   (unpacked packages). This provides a considerable speedup. Thanks Evan

   Dandrea.

 * crash-digger: Add --sandbox-dir option and pass it to apport-retrace.

 * Fix the whole code to be PEP-8 compatible, and enforce this in test/run by

   running the "pep8" tool.

 * GTK UI tests: Ensure that there are no GLib/GTK warnings or criticals.

 * Support Python 3. Everything except the launchpad crashdb backend now works

   with both Python 2 and 3. An important change is that the load(),

   write(), and write_mime() methods of a ProblemReport and apport.Report

   object now require the file stream to be opened in binary mode.

 * data/apport: Ignore a crash if the executable was modified after the process

   started. This often happens if the package is upgraded and a long-running

   process is not stopped before. (LP: #984944)

 * Add test cases for apport-unpack.

 * apport-retrace: Add information about outdated packages to the

   "RetraceOutdatedPackages" field.

 * ui.py: Drop python-xdg dependency, use ConfigParser to read the .desktop

   files.

Bug fixes:

 * apport-gtk: Work around GTK crash when trying to set pixmap on an already

   destroyed parent window. (LP: #938090)

 * data/dump_acpi_tables.py: Fix crash on undefined variable with non-standard

   tables. (LP: #982267)

 * backends/packaging-apt-dpkg.py: Fix crash if a package is installed, but has

   no candidates in apt. (LP: #980094)

 * data/general-hooks/generic.py: Bump minimum free space requirement from 10

   to 50 MB. 10 is not nearly enough particularly for /tmp. (LP: #979928)

 * hookutils.py, recent_logfile(): Use a default limit of 10000 lines and call

   "tail" instead of reading the whole file. This protects against using up all

   memory when there are massive repeated log messages. (LP: #984256)

 * apport-gtk: Do not assume that an icon requested for size 42 actually

   delivers size 42; some themes do not have this available and deliver a

   smaller one instead, causing overflows. Also, copy the image as

   gtk_icon_theme_load_icon() returns a readonly result which we must not

   modify. (LP: #937249)

 * ui.py: Don't show the duplicate warning when the crash database does not

   accept the problem type, and they are just being sent to whoopsie. Thanks

   Evan Dandrea. (LP: #989779)

 * report.py: Correctly escape the file path passed to gdb.

 * apport-gtk, apport-kde: Do not show the information collection progress

   dialog if the crash database does not accept this kind of report. In that

   case whoopsie will upload it in the background and the dialog is not

   necessary.  (LP: #989698)

2.0.1 (2012-04-10)

------------------

Bug fixes:

 * test_ui_gtk.py: Disable package hooks for the tests, as they might ask for

   sudo passwords and other interactive bits, and thus make the tests hang.

 * test_backend_apt_dpkg.py: Fix checks for the installation of -dbgsym

   packages. This should always happen, as the sandboxes have a ddeb apt

   source. Only make it conditional on the system apt sources in the "use

   system config" test.

 * test_report.py: Sleep a bit after calling our test crash script, to ensure

   the kernel has time to finish writing the core file.

 * generic package hook: Also check /tmp for enough space. Thanks Brian Murray.

   (LP: #972933)

 * problem_report.py, write_mime(): Fix regression from version 1.95: Add a

   value as attachment if it is bigger than 1000 bytes, not if it is bigger

   than 100. (LP: #977882)

Improvements:

 * packaging-apt-dpkg.py: Avoid constructing and updating the apt.Cache()

   objects multiple times, to speed up retracing. Thanks Evan Dandrea.

   (LP: #973494)

2.0 (2012-03-30)

----------------

This is the final 2.0 release, featuring the overhauled and simplified GUI,

support for whoopsie-daemon, and client-side duplicate checking.

Bug fixes:

 - report.py, anonymize(): Only replace whole words, not substrings.

   (LP: #966562)

 - apport_python_hook.py: Fix filtering of org.freedesktop.DBus.Error.NoReply

   exceptions. (LP: #958575)

 - crashdb.py: When publishing the crash database, cut hash file names after

   quoting, to avoid that the quoting causes them to become too long.

   (LP: #968070) This also uncovered that known() did not actually find any

   signature which contained an URL-quoted character, therefore breaking

   client-side duplicate checking in a lot of cases. Double-quote the file name

   now, as urlopen() unquotes it.

 - Add a new crash database option "problem_types" and a CrashDatabase method

   "accepts(report)". This can be used to stop uploading particular problem

   report types to that database. E. g. a distribution might decide to not get

   "Crash" reports any more after release.  Document the new option in

   doc/crashdb-conf.txt.

 - ui.py: Do not upload a report if the crash database does not accept the

   report's type. This behaviour is not really correct, but necessary as long

   as we only support a single crashdb and have whoopsie hardcoded.  Once we

   have multiple crash dbs, we need to not even present the data if none of the

   DBs wants the report. See LP #957177 for details. (LP: #968121)

 - ui.py: Do not short-circuit information collection if report already has a

   "DistroRelease" field, as the GUIs add that in some cases. Check for

   "Dependencies" instead. This fixes information collection for kernel

   problems (which now has a full GTK GUI test case). (LP: #968488)

1.95 (2012-03-22)

-----------------

Bug fixes:

 - ui.py: Ensure that the report file is readable by the crash reporting daemon

   after running through collect_info(). Thanks Evan Dandrea.

 - apport-gtk, apport-kde: Set the window title to the distribution name, as

   per http://wiki.ubuntu.com/ErrorTracker#error . Thanks Evan Dandrea.

   (LP: #948015)

 - test/run: Ignore obsolete packages on the system, to avoid breaking the GUI

   tests due to them.

 - apport-gtk, apport-kde: When reporting a "system crash", don't say "... of

   this program version", but "...of this type", as we don't show a program

   version in the initial dialog (https://wiki.ubuntu.com/ErrorTracker#error)

   (LP: #961065)

 - problem_report.py, write_mime(): Do not put a key inline if it is bigger

   than 1 kB, to guard against very long lines. (LP: #957326)

 - etc/cron.daily/apport: Do not remove whoopsie's *.upload* stamps every day,

   only if they are older than a week. whoopsie comes with its own cron job

   which deals with them. Thanks Steve Langasek. (LP: #957102)

 - report.py, mark_ignore(): Fix crash if executable went away underneath us.

   (LP: #961410)

 - apport-gtk: Do not compare current continue button label against a

   translated string.  Instead just remember whether or not we can restart the

   application. (LP: #960439)

 - hookutils.py, command_output(): Add option to keep the locale instead of

   disabling it.

 - hookutils.py, command_output(): Actually make the "input" parameter work,

   instead of causing an eternal hang. Add tests for all possible modes of

   operation.

 - hooktuils.py: Change root_command_output() and attach_root_command_outputs()

   to disable translated messages (LC_MESSAGES=C) only as part of the command

   to be run, not already for the root prefix command. This will keep the

   latter (gksu, kdesudo, etc.) translated. (LP: #961659)

 - apport-gtk: Cut off text values after 4000 characters, as Gtk's TreeView

   does not get along well with huge values. KDE's copes fine, so continue to

   display the complete value there. (LP: #957062)

 - apport-gtk: Make details window resizable in bug reporting mode.

 - crashdb.py, known(): Check the address signature duplicate database if the

   symbolic signature exists, but did not find any result. (LP: #103083)

 - ui.py: Run anonymization after checking for duplicates, to prevent host or

   user names which look like hex numbers to corrupt the stack trace.

   (LP: #953104)

 - apport-gtk: Require an application to both have TERM and SHELL in its

   environment to consider it a command line application that was started by

   the user. (LP: #962130)

 - backends/packaging-apt-dpkg.py, _check_files_md5(): Fix double encoding,

   which caused UnicodeDecodeErrors on non-ASCII characters in an md5sum file.

   (LP: #953682)

 - apport-kde, apport-gtk: Only show "Relaunch" if the report has a

   ProcCmdline, otherwise we cannot restart it. (LP: #956173)

Improvements:

 - hookutils.py, attach_alsa(): Add the full "pacmd list" output instead of

   just sinks and sources. Thanks David Henningsson.

 - apport-gtk, apport-kde: Show the ExecutablePath while we're collecting data

   for the crash report. Thanks Evan Dandrea. (LP: #938707).

1.94.1 (2012-03-07)

-------------------

Bug fixes:

 - test_ui_kde.py: Re-enable inadvertently disabled "bug report for uninstalled

   package" test.

 - ui.py, collect_info(): Do not assume that reports have a "ProblemType"

   field. This is not the case when updating a bug. (LP: #947519)

 - apport-cli: Consistently handle unicode vs. byte arrays. (LP: #946207)

 - report.py, anonymize(): Fix crash when the hostname or user name contain

   non-ASCII characters. (LP: #945230)

 - packaging-apt-dpkg.py: Fix UnicodeDecodeError on unexpected md5sum output.

   (LP: #921037)

 - apport-gtk: Fix handling of non-ASCII strings in message dialogs.

   (LP: #865394)

1.94 (2012-03-02)

-----------------

Bug fixes:

 - apport: Set the group of written reports to "whoopsie" if that group exists.

 - Fix tests to run properly against the system-installed modules and binaries.

 - test/run: Run under LC_MESSAGES=C to avoid test failures due to translated

   strings.

 - general-hooks/generic.py: Also attach xsession-errors for programs that link

   to libgtk-3.

 - launchpad.py: Properly handle "Expired" status, to avoid marking new bugs as

   duplicates of expired ones. (LP: #941854)

 - apport: Fix crash if the "whoopsie" group does not exist. (LP: #942326)

 - report.py, crash_signature(): Do not put "<module>" frames into Python crash

   signatures that happen outside of function/method calls. Fall back to the

   file/line number as a frame description instead. This will do a much better

   job at disambiguating e. g. different ImportError crashes. (LP: #920403)

 - Make "binary changed since the time of the crash" error message more

   comprehensible, thanks Paolo Rotolo. (LP: #942830)

 - crashdb.py, check_duplicate(): It can happen that a bug gets identified as

   being a duplicate of bug S by symbolic signatures and a duplicate of bug A

   by address signatures. Empirical evidence shows that this is due to the

   unavoidable jitter in stack traces (A and S not being identified as

   duplicates as their signatures differ slightly) and not a logic error. So

   instead of erroring out, duplicate all three bugs and keep the lowest number

   as the master ID. (LP: #943117)

 - Revert the usage of multiple nested threads during data collection, and

   switch back to only using one UI thread. The UI implementations can, and now

   do, decide between showing a spinner and showing a progress dialog in the

   ui_*_info_collection_progress() methods. This fixes libX11 crashes when

   multiple UI threads do changes concurrently (LP: #901675), and also avoids

   multi-thread induced crashes in Pango (LP: #943661). The removal of the

   collect() method also fixes the new crashes in it. (LP: #942098, #939803)

 - ui.py, get_desktop_entry(): Fix crash on uninstalled package. (LP: #940984)

 - data/unkillable_shutdown: Fix crash on race condition when PID goes away

   while the report is created. (LP: #546369)

 - apport/hookutils.py, pci_devices(): Fix crash on unexpected lines from

   lspci. (LP: #904489)

 - Drop hardcoded "Ubuntu" words again which crept in with the whoopsie support

   merge. Use the DistroRelease: field.

 - apport-kde: Fix Home page URL in KApplication metadata.

 - apport-gtk: Fix resizability and size after hiding details. (LP: #405418)

Improvements:

 - test/run: Drop "local" argument. This now tests against the source tree when

   run in the source tree root, and against the system libraries/programs when

   run from anywhere else.

 - test/run: Consider command line arguments as test names and only run those

   when given. Also support just running a single test.

 - testsuite: Force the skipping of online tests when $SKIP_ONLINE_TESTS is

   set.

 - hookutils.py, xsession_errors(): Add a reasonable default pattern which

   matches glib-style warnings, errors, criticals etc. and X window errors.

   In data/general-hooks/generic.py, call it with that default instead of the

   rather incomplete custom pattern. (LP: #932660)

 - packaging.py: Add get_package_origin() method, and implement it for

   apt-dpkg.

 - report.py, add_package_info(): Add "[origin: ...]" tag to "Package" and

   "Dependencies" fields for any package which is not native to the

   distribution. If any such package is present, tag the report with

   "third-party-packages" in data/general-hooks/generic.py. (LP: #927912)

 - apport/packaging.py: Add get_uninstalled_package() method as a helper method

   for the test suite. Use it instead of a hardcoded Debian/Ubuntu specific

   name in test/test_hooks.py.

 - test/test_ui_{gtk,kde}.py: Add test cases for complete UI workflow runs for

   reporting a bug against an installed/uninstalled package, and reporting a

   crash with and without showing details. This reproduces the recent crashes

   like LP #901675 or LP #943661.

 - test_ui.py: Add a test case for reporting a complete report on uninstalled

   package. This happens when reporting a problem from a different machine

   through copying a .crash file.

 - test/run: Add a test that there are no hardcoded "Ubuntu" words in the

   source. The code should use the DistroRelease: field or lsb_release.

1.93 (2012-02-23):

------------------

Bug fixes:

 - apport-gtk: Fix crash on nonexisting icon. Thanks Evan Dandrea.

   (LP: #937354)

 - ui.py, open_url(): Revert back to calling sudo instead of dropping

   privileges ourselves; with the latter, calling firefox as the sudo'ing user

   fails. (LP: #916810, #938128)

 - ui.py: Fix aborting with "AssertionError" if the report is already known,

   but without an URL. (LP: #938778)

 - launchpad.py: If a bug is already known, but the report is private, do not

   send the report. There is little sense piling up lots of duplicates.

   (LP: #938700)

 - test/crash: Fix regression of test_crash_apport(), consider $TERM a

   non-sensitive variable.

 - ui.py: Fix test failures for data collection progress, they are not expected

   to happen for "ProblemType: Crash" any more (happens in the background

   during sending, or if user clicks on "Show Details").

 - test/hooks: Use a package from Debian/Ubuntu main, so that this works better

   during package builds on build servers.

 - test/python: Do not assume that /var/crash/ exists. Use /var/tmp/ for the

   fake binaries instead.

 - data/general-hooks/parse_segv.py: Fix test case name.

 - ui.py: Fix crash on invalid core dumps. (LP: #937215)

 - launchpad.py: Fix crash on unicode report titles. (LP: #896626)

Improvements:

 - apport-gtk: Show the most interesting fields first in the details view.

 - do-release: Call pyflakes and abort on errors other than unused imports.

 - Move all test suites out of the code modules into test/test_<module>.py.

   This avoids having to load it every time the program runs, and also allows

   running the tests against the installed version of Apport.

 - Clean up the other executable test script in test/* and change them to the

   same structure as the module tests.

1.92 (2012-02-20):

------------------

Bug fixes:

 - ui.py: Fix wrong creation of "~" folder instead of expanding it to home

   directory when using "Examine locally". Thanks Jason Conti! (LP: #909149)

 - Replace file() calls with open() for Python 3 compatibility. Thanks Colin

   Watson!

 - launchpad.py: Avoid sending tag names with upper case. (LP: #924181)

 - report.py, crash_signature_addresses(): Fix crash if report does not have

   "Signal".

 - apport-gtk: Fix resize handling of expander in details window. Thanks Thomas

   Bechtold! (LP: #930562)

 - Clean up unnecessary imports. Thanks Evan Dandrea!

Improvements:

 - man/apport-bug.1: Mention where crash files are stored. Thanks David

   Kastrup.

 - hookutils.py, attach_hardware(): Sort ProcModules, thanks Brian Murray.

 - launchpad.py: Keep "Dependencies" attachment in duplicates. Thanks Brian

   Murray.

 - Reorganize the GNOME and KDE user interface to do the crash notifications

   and detail browser in a single dialog. Add test/gtk and test/kde tests to

   check expected dialog layout for different cases. Thanks Evan Dandrea!

 - Add support for the whoopsie-daisy crash reporting daemon by creating

   zero-byte .upload file stamps for crash reports. Thanks Evan Dandrea!

1.91 (2012-01-18):

------------------

Bug fixes:

 - crashdb.py, check_duplicate(): If a crash has a signature but no existing

   duplicate in the DB, also check for an existing address signature duplicate

   in the DB.

 - apport-retrace: Use DistroRelease specific subdirectory of the cache dir for

   mapping a file to a package, as these maps are release specific.

 - packaging-apt-dpkg.py: Refresh Contents.gz cache if it is older than one

   day.

 - crashdb.py: Ensure that address_signature duplicate db table does not have

   multiple identical signatures by making it a primary key. Bump the db format

   to "3". Existing databases need to be migrated manually as SQLite does not

   allow adding a "PRIMARY KEY" constraint to existing tables.

 - crashdb.py: Do not add a new address signature entry if one already exists.

 - apport-cli: Fix UnicodeDecodeError on unicode report values. (LP: #275972)

 - launchpad.py: Only set bug task importance if it is undecided.

 - apport-retrace: Fix "an useful" typo. (LP: #911437)

 - report.py: Filter out frames which are internal kernel/glibc implementation

   details and not stable across duplicates. In particular, filter out

   __kernel-syscall() and the SSE stubs.

 - crashdb.py: Remove debugging leftover which completely disabled bug pattern

   checking.

 - report.py: Update reading AssertionMessage. Current (e)glibc turned

   __abort_msg from a simple static string into a struct.

Improvements:

 - Change permissions of .crash files from 0600 to 0640, so that /var/crash can

   be made g+s and crash handling daemons can access those.

 - Python exceptions: Blacklist DBus.Error.NoReply. It does not help to get

   these traces from the client-side application, you need the actual exception

   in the D-Bus server backend instead. (LP: #914220)

 - Support /etc/apport/whitelist.d/ similarly to /etc/apport/blacklist.d/, for

   cases like installer environments where only crashes of a few selected

   programs should be reported.

1.90 (2011-11-24):

------------------

First beta release of 2.0 which introduces client-side duplicate checking.

Bug fixes:

 - backends/packaging-apt-dpkg.py: Fix another test case failure when ddeb

   repository is not enabled.

 - backends/packaging-apt-dpkg.py: Fix handling of explicit cache directory

   name when it is a relative path.

 - launchpad.py: Only query for bugs after 2011-08-01, to avoid timeouts.

 - ui.py: Also anonymize standard bug title. (LP: #893863)

 - launchpad.py: Current Launchpad cannot have private bugs which affect

   multiple projects. Fix test suite accordingly.

Improvements:

 - report.py: Break out new method stacktrace_top_function() from

   standard_title(), so that other parts of the code can use this as well.

 - launchpad.net: When sending retraced results back to the bug report, update

   the topmost function in the bug title. (LP: #869970)

 - report.py, add_gdb_info(): Add a new field "StacktraceAddressSignature"

   which is a heuristic signature for signal crashes. This should be used if

   crash_signature() fails, i. e. the Stacktrace field does not have enough

   symbols. This can be used to check for duplicates on the client side,

   provided that the crash database server supports querying for these.

   Do not expose this field when uploading to crash databases though, as it can

   be recomputed from the already existing information (ProcMaps and

   Stacktrace) and thus would just clutter the reports.

 - crashdb.py: Add a table "version" with the database format version. Add

   automatic upgrading to the most current format.

 - crashdb.py: Put address signatures from reports checked with

   check_duplicate() into the duplicate database, so that implementations of

   known() can check for these.

 - dupdb-admin: Add "publish" dupdb-admin command which exports the

   duplicate database into a set of text files suitable for WWW publishing.

 - crashdb.py: Add new method "known(report)" which can be implemented to check

   if the crash db already knows about the crash signature. If so, the report

   will not be uploaded, and instead the user will be directed to the existing

   report URL (if available), similar to bug patterns. The default

   implementation checks this format, if the crash database is initialized with

   a "dupdb_url" option pointing to the exported database.

 - launchpad.py: Override known() to check if the master bug is actually

   accessible by the reporter, and is not tagged with "apport-failed-retrace"

   or "apport-request-retrace"; otherwise file it anyway.

 - crash-digger: Add --publish-db option to conveniently integrate duplicate DB

   publication (similar to dupdb-admin publish) into retracer setups.

 - launchpad.py: Attach updated stack traces from a duplicate to the master bug

   if it failed retracing previously or has an "apport-request-retrace" tag.

   (LP: #869982)

 - apport-kde, apport-gtk: Support the "Annotation" field for custom dialog

   titles for "Crash" and "Package" problem types as well, not just for

   "Kernel". (LP: #664378)

1.26 (2011-11-11):

------------------

Bug fixes:

 - backends/packaging-apt-dpkg.py: Port to current python-apt API.

 - hookutils.py: Fix path_to_key() to also work with unicode arguments.

 - test/crash: Exit successfully if apport is not enabled in the system. This

   allows packages to run the test suite during build.

 - report.py, add_proc_info(): Correctly handle "python -m <modulename>"

   programs as being interpreted and determine the appropriate module path.

 - Fix some import statements to also work for the system-installed test suite.

 - test/run: Fix testing data/general-hooks/parse_segv.py when called in

   system-installed mode.

 - apport/ui.py: Clean up test .crash file after test cases.

 - Fix tests when running as root.

 - setup.py: Fix crash when "javac -version" fails.

 - README: Update command for one-time enablement.

 - backends/packaging-apt-dpkg.py: Fix interleaving usage of install_packages()

   with other operations such as get_version(), by resetting the apt status

   after building and using the sandbox.

 - report.py test suite: Remove requirement that $USER is set, which makes it

   easier to run this from package build environments.

 - apport/ui.py, test/crash: Use "yes" as test process instead of "cat". The

   former is less likely to run already, and does not depend on having a stdin,

   so it runs better in test environments like autopkgtest.

 - backends/packaging-apt-dpkg.py: Fix tests if system does not have a dbgsym

   apt source.

Improvements:

 - Ignore a crash if gnome-session is running and says that the session is

   being shut down. These often die because X.org or other services are going

   away, are usually harmless, and just cause a lot of clutter in bug trackers.

   (LP: #460932)

 - test/crash: Rewrite using Python's unittest, to be in line with other tests,

   and be easier to maintain and extend.

1.25 (2011-11-02):

------------------

Improvements:

 - Add new response "Examine locally" to presenting the report details, which

   runs apport-retrace in the chosen mode in a terminal. This should be made

   available for crash reports if apport-retrace and a Terminal application are

   installed; add an abstrace UI method for this. (LP: #75901)

 - apport-gtk: Add "Examine locally..." button, and implement

   ui_run_terminal().

 - apport-cli: Add "Examine locally..." responses, and implement

   ui_run_terminal().

 - apport-cli: Greatly speed up displaying large reports. This also changes the

   format to avoid indenting each line with a space, and visually set apart the

   keys in a better way.

 - apport_python_hook.py: Move tests out of this file into test/python, to

   avoid having to parse the unit tests at each Python startup.

 - test/python: Also make tests work if Python hook is not installed in

   system's sitecustomize.py.

 - packaging.py: Add get_modified_conffiles() API, and implement it in

   packaging-apt-dpkg.py.

 - hookutils.py: Add attach_conffiles().

 - hookutils.py: Add attach_upstart_overrides().

Bug fixes: 

 - launchpad.py: Remove "Ubuntu" in bug response, replace with "this software".

   (LP: #883234)

 - apport-kde: Rearrange order of imports to get intended error message if

   PyKDE is not installed.

 - packaging-apt-dpkg.py: Ignore hardening-wrapper diversions, to make

   gcc_ice_hook work if hardening-wrapper is installed.

 - apport_python_hook: Respect $APPORT_REPORT_DIR.

 - apport_python_hook: Limit successive crashes per program and user to 3 per

   day, just like signal crashes. (LP: #603503)

 - packaging-apt-dpkg.py: Skip online tests when there is no default route.

 - ui.py: Fix test suite to not fail if system has some obsolete or non-distro

   packages.

1.24 (2011-10-19):

------------------

Bug fixes:

 - backends/packaging-apt-dpkg.py, install_packages(): Also copy

   apt/sources.list.d/ into sandbox.

 - backends/packaging-apt-dpkg.py, install_packages(): Install apt keyrings

   from config dir or from system into sandbox. (LP: #856216)

 - packaging.py, backends/packaging-apt-dpkg.py: Define that install_packages()

   should return a SystemError for broken configs/unreachable servers etc., and

   fix the apt/dpkg implementation accordingly.

 - apport-retrace: Don't crash, just give a proper error message if servers are

   unreachable, or configuration files are broken. (LP: #859248)

 - backends/packaging-apt-dpkg.py: Fix crash when /etc/apport/native-origins.d

   contains any files. (LP: #865199)

 - hookutils, recent_logfile(): Fix invalid return value if log file is not

   readable. (LP: #819357)

 - test/crash: Fix race condition in the "second instance terminates

   immediately" check.

 - hookutils.py: Replace attach_gconf() with a no-op stub. It used static

   python modules like "gconf" which broke the PyGI GTK user interface, and

   gconf is rather obsolete these days.

 - ui.py, open_url(): Greatly simply and robustify by just using xdg-open. This

   already does the right thing wrt. reading the default browser from GNOME,

   KDE, XCE, and other desktops. (LP: #198449)

 - data/general-hooks/generic.py: Only attach ~/.xsession_errors if the bug is

   reported in the same XDG session as the crash happened. (LP: #869974)

 - Ignore crashes for programs which got updated in between the crash and

   reporting. (LP: #132904)

 - Special-case crashes of 'twistd': Try to determine the client program and

   assign the report to that, or fail with an UnreportableReason. (LP: #755025)

 - apport-gtk: In bug update mode, make details dialog resizable and fix

   default size. (LP: #865754)

 - apport-gtk: Fix crash if report does not have ProcCmdline. (LP: #854452)

 - hookutils.py, attach_wifi(): Anonymize ESSID and AP MAC from "iwconfig"

   output. (LP: #746900)

 - test/crash: Fix test failure if user is not in any system groups.

 - test/crash: Change to /tmp/ for test crash process, to fix failure if the

   user that runs the test suite cannot write into the current directory.

   (LP: #868695)

 - ui.py: Improve error message if package is not a genuine distro package.

   Thanks to Ronan Jouchet. (LP: #559345)

Improvements:

 - apport-retrace: Add --timestamp option to prepend a timestamp to log

   messages. This is useful for batch operations.

 - crash-digger: Call apport-retrace with --timestamps, to get consistent

   timestamps in log output.

 - hookutils.py: Add two new functions attach_gsettings_package() and
