• Remove Fedora Docker images, they don't have tar
• Do include .pyc files in packages, so reproduction take same code path
• Don't use the experiment's resolv.conf file
• Fix handling of files opened in read-write mode

1.0.8 (2016-10-07)

Behavior changes:

• No longer default to overwriting trace directories. ReproZip will ask what to do or exit with an error if one of --continue/--overwrite is not provided

Bugfixes:

• Fix an issue identifying Debian packages when a file's in two packages
• Fix Python error Mixing iteration and read methods would lose data
• Fix reprounzip info showing some numbers as 0 instead of hiding them in non-verbose mode
• Another fix to X server IP determination for Docker

• Add filters to remove some common files types from packed files (.pyc) or detected input files (.py, .so, ...)
• Add JSON output format to reprounzip info
• Allow using the Virtualbox display to reproduce X11-enabled experiments

1.0.7 (2016-08-22)

Bugfixes:

1.0.6 (2016-06-25)

(reprounzip-vistrails didn't change)

Bugfixes:

• Fixes error using Docker with --enable-x11 on Python 3

Enhancements:

• docker run gets a --detach command, to keep the container running (useful for starting servers on remote machines)
• Restrictions on upload and download commands have been relaxed, in particular it is possible to download input files as well as output files
• Don't compress outer tar (data is still compressed); this should make some operations (like reprounzip info) faster
• Add reprozip combine, useful to combine multiple traces into one (as different runs). Handy if running distributed experiments on shared filesystem (MPI)

1.0.5 (2016-04-07)

(reprounzip-vagrant didn't change)

Bugfixes:

• Correctly download parameters from server
• More reliable way of determining X server IP without using /bin/ip

Behavior changes:

• reprounzip will no longer run on Python 2.6

Bugfixes:

• Fixes file download not using cache if URL is HTTPS
• Fixes unpacking with directory or chroot for some multi-step packages

Features:

• Add --docker-option to pass raw options to Docker
• You can use run or run - to run every run, regardless of their number
• Allow download <name>, shortcut for download <name>:./<name> (downloads to current directory, keep name)
• Allow download --all
• Add --input and --output to showfiles
• Implement vagrant suspend command
• Do file downloads with requests
• Download a parameter file to update URLs and image names without waiting for the next ReproZip version

1.0.3 (2015-12-02)

Bugfixes:

• You could get a traceback with some unpackers (not Vagrant) on some packages that explicitely pack the / directory
• Some environment variables prevented running, such as bash exported functions.

Features:

• Remove setup directory if setup fails, so you can run setup again without gettin target directory exists
• Add --set-env and --pass-env to run

1.0.2 (2015-10-26)

Bugfixes:

• You can now use X11 forwarding even with a remote Docker daemon
• reprounzip-vagrant now works in paths containing spaces

1.0.1 (2015-10-12)

Bugfixes:

• Files opened through a shebang were stored with a wrong process number
• Running with Docker on non-Linux machine didn't work (e.g. docker-machine); now only X11 doesn't work.
• Some fixes to the graph command

Features:

• --memory option for reprounzip vagrant setup, to set the VM's RAM.

1.0.0 (2015-09-30)

Behavior change:

• .rpz pack format changed (version 1 -> 2). Pack is now uncompressed, data is in a nested TGZ archive; allows faster retrieval of metadata (config & trace).
• reprozip trace warnings are now info messages; won't show up without -v

Bugfixes:

• After restarting a Vagrant machine, /dev and /proc wouldn't be mounted anymore
• Files or links referenced in a shebang could be missed by the tracer

Features:

• Runs in the configuration file now have an 'id' field, that will be shown by 'reprounzip info' and can be selected when running
• Reworked reprounzip graph: level of details, regex filters & replace, JSON output
• Added run argument to reprounzip showfiles, to show inputs & outputs of a single run

0.7.2 (2015-08-24)

Behavior change:

• reprounzip-docker will now re-use the resulting image from the previous run when running again, instead of starting from scratch; a 'reset' command has been added to undo runs and uploads.

Bugfixes:

• Couldn't reset an input file to the original (packed) file on Python 3
• Don't show a warning about network connections when they didn't succeed
• Hide traceback when failing because Vagrant is not installed
• Fix input/output file detection assigning files to the same run
• Fix selecting multiple runs in 'docker run'

Features:

• Display the relative portion of the path when unhandled xxx_at() syscalls are used, to give an idea of what's been missed
• Add --dont-find-inputs-outputs to reprozip trace and reset, so you can clear that out if too many files would be selected (or if you don't use the feature)
• Rewrote reprounzip-vistrails plugin; uses a proper VisTrails package that now lives in the VisTrails distribution.
• Check pack format in unpackers; won't try to unpack version 2
• It is now possible to select multiple runs with unpackername run 1-4

0.7.1 (2015-07-14)

(reprozip only)

Bugfixes:

• Files (or links) created with rename, link or symlink then read will no longer be packed.
• A buffer overflow could happen in the log module, for instance when the experiment passes a very long argument to execve (over 4kB in a single argument) and running in debug mode (-v -v)

0.7 (2015-07-07)

Behavior change:

• No longer accept passing -v after the subcommand; use reprozip -v testrun ..., not reprozip testrun -v.
• Rely on PTHREAD_EVENT_EXEC to handle execve(). Makes tracing more reliable, and enable it to behave correctly on weird kernels (like UML).
• Rely on PTRACE_EVENT_FORK to handle fork/vfork/clone. Fixes vfork() deadlocking under trace.
• Completely changed the structure of input and output files (old packs will still be loaded, but new packs are not retro-compatible).
• Using one of the run commands without specifying a number will no longer default to running all of them; it will error out if there are multiple runs.

Bugfixes:

• Fix insertion speed in SQLite3 database

Features:

• Makes VMs (Vagrant or Docker) more resilient to massive breakage of system libraries (obliterating /lib or /usr, when using very different operating systems) by putting busybox in / and using rpzsudo.
• No longer use dpkg -S to identify packages, do a single pass over internal dpkg database (this is considerably faster).

0.6.4 (2015-06-07)

(reprounzip-vistrails didn't change)

Bugfixes:

• Tracer: correctly handle chdir() in multi-threaded processes
• Fix leaked file descriptors, eventually making SQLite3 fail
• No longer exceed cmdline length in Dockerfile in big .RPZ pack
• Fixes check_output call when running Docker (not available in Python 2.6)
• Fixes installation of sudo failing if original machine wasn't Debian
• Don't make TAR error status fatal in Dockerfile (might not run; this is needed because Docker mount some files in the container that can't be overwritten)

0.6.3 (2015-05-06)

(reprounzip and plugins only)

Bugfixes:

• Fixes reprounzip-vistrails failing because of reporting
• Fixes reprounzip-vistrails not escaping correctly in XML in some conditions
