Reprozip

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

(reprozip, reprounzip-qt and reprozip-jupyter only)

Bugfixes:
* Fixed reprounzip-qt refusing to close when an experiment is still unpacked, even after the user provided confirmation
* Fixed reprozip-jupyter on Python 3
* Fixed running gnome-terminal from reprounzip-qt, made it preferred over xterm
* Don't duplicate the latest run in the config file when the trace didn't add a run (for example because the command does not exist)

Enhancements:
* Uniformized logos and icons
* Native terminal opened by reprounzip-qt waits for a key after success before closing
* Officially support reprounzip-qt and reprozip-jupyter on Python 3

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

Bugfixes:
* Fix uninitialized return value making some xxx_at() calls abort the trace
* Fix some other warnings via static analysis

Enhancements:
* Show a warning when executing a file that has the set-uid or set-gid bit set, since Linux will not give it its privileges, making it confusing for users why their run failed
* Make reprounzip-docker run even without a TTY
* Correctly handle experiment returning non-0 in Docker
* The C extension now logs through Python's logging facilities ('reprozip' logger)
* Collect usage information from reprounzip-qt as well

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

(reprozip, reprounzip-qt and reprozip-jupyter only)

Bugfixes:
* Fix some kernel/libc issuing unrecognized `openat()` calls, resulting in files missing in the trace
* Fix `openat()` calls recording read-write as simply write
* Fix double-click on .RPZ file

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

Bugfixes:
* Write timestamp in config with timezone offset
* Always fix up PATH on MacOS (to pick up Docker)
* Don't have reprounzip-qt choke on MacOS's `-psn_x_xxxx` arguments
* Fix "Couldn't find reprounzip command" in the GUI on Windows if installed from the installer and opened a package by double-click

Enhancements:
* Improve DOT graph layout
* Don't silently overwrite output with `reprounzip graph`
* Add `--regex-include` to `reprounzip graph`
* `reprozip trace` now returns 125 for tracing errors (previously 1), and returns the traced program's exit code otherwise (previously always 0)
* Manpages are available

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

Bugfixes:
* Correctly escape shell commands containing backticks
* Overwrite tty prompt works correctly on Python 3
* Fix /proc in vagrant-chroot and chroot having outside mounts
* Fix ANSI escapes showing in Qt terminal dialog
* Fix reprozip combine crash on Python 3.6 (patch from James Clarke)
* Using `graph --packages drop` together with `--json` no longer crashes

Enhancements:
* New reprozip-jupyter tool to trace and reproduce Jupyter notebooks
* reprozip_jupyter can be registered as a Jupyter extension to trace notebooks from the Jupyter web interface
* The Qt GUI knows to run packages with reprozip-jupyter if they are notebook environments (kernels) unpacked with Docker (and reprozip-jupyter is installed)
* Add `--docker-cmd` to reprounzip-docker to select the Docker command (for example `--docker-cmd="sudo docker"`)
* Implement `--expose-port` option for Vagrant and Docker (no need for `--docker-option=-p...`)
* Add docker-machine support to GUI (select which machine to use)
* Better binaries for MacOS
* Automatically register reprounzip-qt to open .RPZ files on Linux
* Register ReproUnzip with Windows from installer
* Add icon from heng2j

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

Bugfixes:
* Fix CentOS Docker image versions
* 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
