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. | |
