|
This is a tool for managing a recorded version number in distutils-based |
|
python projects. The goal is to remove the tedious and error-prone "update |
|
the embedded version string" step from your release process. Making a new |
|
release should be as easy as recording a new tag in your version-control |
|
system, and maybe making new tarballs. |
|
|
|
|
|
## Quick Install |
|
|
|
* `pip install versioneer` to somewhere to your $PATH |
|
* add a `[versioneer]` section to your setup.cfg (see below) |
|
* run `versioneer install` in your source tree, commit the results |
|
|
|
## Version Identifiers |
|
|
|
Source trees come from a variety of places: |
|
|
|
* a version-control system checkout (mostly used by developers) |
|
* a nightly tarball, produced by build automation |
|
* a snapshot tarball, produced by a web-based VCS browser, like github's |
|
"tarball from tag" feature |
|
* a release tarball, produced by "setup.py sdist", distributed through PyPI |
|
|
|
Within each source tree, the version identifier (either a string or a number, |
|
this tool is format-agnostic) can come from a variety of places: |
|
|
|
* ask the VCS tool itself, e.g. "git describe" (for checkouts), which knows |
|
about recent "tags" and an absolute revision-id |
|
* the name of the directory into which the tarball was unpacked |
|
* an expanded VCS keyword ($Id$, etc) |
|
* a `_version.py` created by some earlier build step |
|
|
|
For released software, the version identifier is closely related to a VCS |
|
tag. Some projects use tag names that include more than just the version |
|
string (e.g. "myproject-1.2" instead of just "1.2"), in which case the tool |
|
needs to strip the tag prefix to extract the version identifier. For |
|
unreleased software (between tags), the version identifier should provide |
|
enough information to help developers recreate the same tree, while also |
|
giving them an idea of roughly how old the tree is (after version 1.2, before |
|
version 1.3). Many VCS systems can report a description that captures this, |
|
for example `git describe --tags --dirty --always` reports things like |
|
"0.7-1-g574ab98-dirty" to indicate that the checkout is one revision past the |
|
0.7 tag, has a unique revision id of "574ab98", and is "dirty" (it has |
|
uncommitted changes. |
|
|
|
The version identifier is used for multiple purposes: |
|
|
|
* to allow the module to self-identify its version: `myproject.__version__` |
|
* to choose a name and prefix for a 'setup.py sdist' tarball |
|
|
|
## Theory of Operation |
|
|
|
Versioneer works by adding a special `_version.py` file into your source |
|
tree, where your `__init__.py` can import it. This `_version.py` knows how to |
|
dynamically ask the VCS tool for version information at import time. |
|
|
|
`_version.py` also contains `$Revision$` markers, and the installation |
|
process marks `_version.py` to have this marker rewritten with a tag name |
|
during the `git archive` command. As a result, generated tarballs will |
|
contain enough information to get the proper version. |
|
|
|
To allow `setup.py` to compute a version too, a `versioneer.py` is added to |
|
the top level of your source tree, next to `setup.py` and the `setup.cfg` |
|
that configures it. This overrides several distutils/setuptools commands to |
|
compute the version when invoked, and changes `setup.py build` and `setup.py |
|
sdist` to replace `_version.py` with a small static file that contains just |
|
the generated version data. |
|
|
|
## Installation |
|
|
|
See [INSTALL.md](./INSTALL.md) for detailed installation instructions. |
|
|
|
## Version-String Flavors |
|
|
|
Code which uses Versioneer can learn about its version string at runtime by |
|
importing `_version` from your main `__init__.py` file and running the |
|
`get_versions()` function. From the "outside" (e.g. in `setup.py`), you can |
|
import the top-level `versioneer.py` and run `get_versions()`. |
|
|
|
Both functions return a dictionary with different flavors of version |
|
information: |
|
|
|
* `['version']`: A condensed version string, rendered using the selected |
|
style. This is the most commonly used value for the project's version |
|
string. The default "pep440" style yields strings like `0.11`, |
|
`0.11+2.g1076c97`, or `0.11+2.g1076c97.dirty`. See the "Styles" section |
|
below for alternative styles. |
|
|
|
* `['full-revisionid']`: detailed revision identifier. For Git, this is the |
|
full SHA1 commit id, e.g. "1076c978a8d3cfc70f408fe5974aa6c092c949ac". |
|
|
|
* `['date']`: Date and time of the latest `HEAD` commit. For Git, it is the |
|
commit date in ISO 8601 format. This will be None if the date is not |
|
available. |
|
|
|
* `['dirty']`: a boolean, True if the tree has uncommitted changes. Note that |
|
this is only accurate if run in a VCS checkout, otherwise it is likely to |
|
be False or None |
|
|
|
* `['error']`: if the version string could not be computed, this will be set |
|
to a string describing the problem, otherwise it will be None. It may be |
|
useful to throw an exception in setup.py if this is set, to avoid e.g. |
|
creating tarballs with a version string of "unknown". |
|
|
|
Some variants are more useful than others. Including `full-revisionid` in a |
|
bug report should allow developers to reconstruct the exact code being tested |
|
(or indicate the presence of local changes that should be shared with the |
|
developers). `version` is suitable for display in an "about" box or a CLI |
|
`--version` output: it can be easily compared against release notes and lists |
|
of bugs fixed in various releases. |
|
|
|
The installer adds the following text to your `__init__.py` to place a basic |
|
version in `YOURPROJECT.__version__`: |
|
|
|
from ._version import get_versions |
|
__version__ = get_versions()['version'] |
|
del get_versions |
|
|
|
## Styles |
|
|
|
The setup.cfg `style=` configuration controls how the VCS information is |
|
rendered into a version string. |
|
|
|
The default style, "pep440", produces a PEP440-compliant string, equal to the |
|
un-prefixed tag name for actual releases, and containing an additional "local |
|
version" section with more detail for in-between builds. For Git, this is |
|
TAG[+DISTANCE.gHEX[.dirty]] , using information from `git describe --tags |
|
--dirty --always`. For example "0.11+2.g1076c97.dirty" indicates that the |
|
tree is like the "1076c97" commit but has uncommitted changes (".dirty"), and |
|
that this commit is two revisions ("+2") beyond the "0.11" tag. For released |
|
software (exactly equal to a known tag), the identifier will only contain the |
|
stripped tag, e.g. "0.11". |
|
|
|
Other styles are available. See [details.md](details.md) in the Versioneer |
|
source tree for descriptions. |
|
|
|
## Debugging |
|
|
|
Versioneer tries to avoid fatal errors: if something goes wrong, it will tend |
|
to return a version of "0+unknown". To investigate the problem, run `setup.py |
|
version`, which will run the version-lookup code in a verbose mode, and will |
|
display the full contents of `get_versions()` (including the `error` string, |
|
which may help identify what went wrong). |
|
|
|
## Known Limitations |
|
|
|
Some situations are known to cause problems for Versioneer. This details the |
|
most significant ones. More can be found on Github |
|
[issues page](https://github.com/warner/python-versioneer/issues). |
|
|
|
### Subprojects |
|
|
|
Versioneer has limited support for source trees in which `setup.py` is not in |
|
the root directory (e.g. `setup.py` and `.git/` are *not* siblings). The are |
|
two common reasons why `setup.py` might not be in the root: |
|
|
|
* Source trees which contain multiple subprojects, such as |
|
[Buildbot](https://github.com/buildbot/buildbot), which contains both |
|
"master" and "slave" subprojects, each with their own `setup.py`, |
|
`setup.cfg`, and `tox.ini`. Projects like these produce multiple PyPI |
|
distributions (and upload multiple independently-installable tarballs). |
|
* Source trees whose main purpose is to contain a C library, but which also |
|
provide bindings to Python (and perhaps other langauges) in subdirectories. |
|
|
|
Versioneer will look for `.git` in parent directories, and most operations |
|
should get the right version string. However `pip` and `setuptools` have bugs |
|
and implementation details which frequently cause `pip install .` from a |
|
subproject directory to fail to find a correct version string (so it usually |
|
defaults to `0+unknown`). |
|
|
|
`pip install --editable .` should work correctly. `setup.py install` might |
|
work too. |
|
|
|
Pip-8.1.1 is known to have this problem, but hopefully it will get fixed in |
|
some later version. |
|
|
|
[Bug #38](https://github.com/warner/python-versioneer/issues/38) is tracking |
|
this issue. The discussion in |
|
[PR #61](https://github.com/warner/python-versioneer/pull/61) describes the |
|
issue from the Versioneer side in more detail. |
|
[pip PR#3176](https://github.com/pypa/pip/pull/3176) and |
|
[pip PR#3615](https://github.com/pypa/pip/pull/3615) contain work to improve |
|
pip to let Versioneer work correctly. |
|
|
|
Versioneer-0.16 and earlier only looked for a `.git` directory next to the |
|
`setup.cfg`, so subprojects were completely unsupported with those releases. |
|
|
|
### Editable installs with setuptools <= 18.5 |
|
|
|
`setup.py develop` and `pip install --editable .` allow you to install a |
|
project into a virtualenv once, then continue editing the source code (and |
|
test) without re-installing after every change. |
|
|
|
"Entry-point scripts" (`setup(entry_points={"console_scripts": ..})`) are a |
|
convenient way to specify executable scripts that should be installed along |
|
with the python package. |
|
|
|
These both work as expected when using modern setuptools. When using |
|
setuptools-18.5 or earlier, however, certain operations will cause |
|
`pkg_resources.DistributionNotFound` errors when running the entrypoint |
|
script, which must be resolved by re-installing the package. This happens |
|
when the install happens with one version, then the egg_info data is |
|
regenerated while a different version is checked out. Many setup.py commands |
|
cause egg_info to be rebuilt (including `sdist`, `wheel`, and installing into |
|
a different virtualenv), so this can be surprising. |
|
|
|
[Bug #83](https://github.com/warner/python-versioneer/issues/83) describes |
|
this one, but upgrading to a newer version of setuptools should probably |
|
resolve it. |
|
|
|
### Unicode version strings |
|
|
|
While Versioneer works (and is continually tested) with both Python 2 and |
|
Python 3, it is not entirely consistent with bytes-vs-unicode distinctions. |
|
Newer releases probably generate unicode version strings on py2. It's not |
|
clear that this is wrong, but it may be surprising for applications when then |
|
write these strings to a network connection or include them in bytes-oriented |
|
APIs like cryptographic checksums. |
|
|
|
[Bug #71](https://github.com/warner/python-versioneer/issues/71) investigates |
|
this question. |
|
|
|
|
|
## Updating Versioneer |
|
|
|
To upgrade your project to a new release of Versioneer, do the following: |
|
|
|
* install the new Versioneer (`pip install -U versioneer` or equivalent) |
|
* edit `setup.cfg`, if necessary, to include any new configuration settings |
|
indicated by the release notes. See [UPGRADING](./UPGRADING.md) for details. |
|
* re-run `versioneer install` in your source tree, to replace |
|
`SRC/_version.py` |
|
* commit any changed files |
|
|
|
## Future Directions |
|
|
|
This tool is designed to make it easily extended to other version-control |
|
systems: all VCS-specific components are in separate directories like |
|
src/git/ . The top-level `versioneer.py` script is assembled from these |
|
components by running make-versioneer.py . In the future, make-versioneer.py |
|
will take a VCS name as an argument, and will construct a version of |
|
`versioneer.py` that is specific to the given VCS. It might also take the |
|
configuration arguments that are currently provided manually during |
|
installation by editing setup.py . Alternatively, it might go the other |
|
direction and include code from all supported VCS systems, reducing the |
|
number of intermediate scripts. |
