| * remove instead of fix stale zipimport._zip_directory_cache data on PyPyJurko Gospodnetić2014-06-151-25/+42
| | | | | | | | | | | | | | | | | | | | PyPy's zipimport._zip_directory_cache implementation does not support direct item assignment, thus breaking our attempts at silently updating the cached zip archive directory information behind the scene. As a workaround, when using PyPy, we fall back to simply clearing the stale cached information. --HG-- extra : amend_source : 991e30244754d8fac042da56ac4cf0ad1a0f50d5

| | | | | | | | | | | | | | | | | | | | | | | | | | This is an extra safety measure to avoid someone holding a reference to this cached data and using its content even after we know that the underlying zip archive has been removed and possibly even replaced.

| | | | | | | | | | | | | | | | | | | | Although the original problematic use case when we are replacing a zipped egg distribution with another zipped egg distribution is now cleanly handled by fixing all existing zipimport.zipimporter loaders, this fix is still valid for cases when replacing a distribution with a non-zipped egg folder. --HG-- extra : source : efd6a8b82bafdbcfad1971b7e0f470e19191be1a
| * fix issue202 - update existing zipimporters when replacing a zipped eggJurko Gospodnetić2014-05-081-30/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When replacing a zipped egg distribution with a different zipped egg, we make all existing zipimport.zipimporter loaders valid again instead of having to go hunting them down one by one. This is done by updating their shared zip directory information cache - zipimport._zip_directory_cache.

| * make easy_install.uncache_zipdir() remove more stale zipimporter instancesJurko Gospodnetić2014-04-151-12/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since paths are case-insensitive on Windows, zipped egg modules may be loaded using different but equivalent paths. Importing each such different path causes a new zipimporter to be instantiated. Removing cached zipimporter instances must then not forget about removing those created for differently spelled paths to the same replaced egg. Other missed zipimporter instances are those used to access zipped eggs stored inside zipped eggs. When clearing zipimporter instances got a given path, we need to clear all the instances related to any of its subpaths as well. --HG-- extra : rebase_source : 86aeadd1e639fbc83d27a0c551fdc2b8a68a6f85

| * quick-fix #168: avoid using stale cached zipped egg dist info in easy_installJurko Gospodnetić2014-04-151-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When installing a zipped egg, into a Python environment with a same named zipped egg already installed, the installation can fail with a zipimport.ZipImportError complaining about a 'bad local header' encountered in the new zip archive. This can occur if setuptools loads the original egg for some reason and the two zip archives have different content. Then if Python attempts to read a file from the new archive, it will expect it in a location pointed to by the original archive's directory. This will report an error if zipimport does not encounter the expected local file start header in the given location. The mismatch between the two archives can be reproduced by installing the same setuptools version (prior to this commit and after commit f40b810acc5f6494735c912a625d647dc2a3c582 that first introduced the requires.txt metadata information file into the setuptools project) twice from its sources - which can randomly fail due to the scenario described above. That will package the zipped egg archive twice, with each of the archives containing slightly different Python modules. In case this causes any of the compressed modules to have different size (easy_install.pyc is often the culprit here), then attempting to read any later file in the zip archive will fail (requires.txt package metadata file is often the culprit here). A similar scenario can be reproduced more consistently by manually modifying the setuptools easy_install.py source file before building the new egg, e.g. by adding some additional empty lines to its start. The underlying reason for this problem is setuptools using zipimporter instances with cached zip archive content directory information from the older zip archive, even after the old archive has been replaced. This patch cleans up only one such old zipimporter instance - one referenced via easy_install command's local_index attribute. That is the one that has been causing all the currently reported/reproduced installation failures. A clean solution needs to make certain there are no more zipimporter instances with stale archive content directory caches left behind after replacing a zipped egg archive with another. There are currently at least the following known potential sources for such stale zipimporter instances (all holding references to Distribution instances that can then hold a reference to a zipimporter related to their zipped egg archive): easy_install command attributes: local_index (Environment with a list of Distributions) package_index (PackageIndex with a list of Distributions) pth_file (PthDistributions with a list of Distributions) global pkg_resources.working_set object (holds a list of Distributions) imported module's __loader__ attribute (zipimporter instance) zipimport._zip_directory_cache sys.path_importer_cache Further debugging & development note: A complete list of all the currently active stale zipimporter instances can be read using CPython's gc module and its object reference introspection functionality (gc.get_objects() & gc.get_referrers()) from inside the uncache_zipdir() method in the setuptools easy_install.py module. That is the method called just after the old arhive has been replaced by the new one and all the stale zipimporter instances were supposed to have been released. --HG-- extra : rebase_source : 041d2819881b8f7e5c4da333a387fc86d4f7b791
