• Update link to avoid a redirect (#982)

pex 2.1.11

pex 2.1.10

2.1.10

This release focuses on the resolver API and resolution performance. Pex 2 resolving using Pip is
now at least at performance parity with Pex 1 in all studied cases and most often is 5% to 10%
faster.

As part of the resolution performance work, Pip networking configuration is now exposed via Pex CLI
options and the NetworkConfiguration API type / new resolver.resolve API parameter.

With network configuration now wired up, the PEX_HTTP_RETRIES and PEX_HTTP_TIMEOUT env var
support in Pex 1 that was never wired into Pex 2 is now dropped in favor of passing --retries
and --timeout via the CLI (See: #94)

• Expose Pip network configuration. (#974)
• Restore handling for bad wheel filenames to .can_add() (#973)
• Fix wheel filename parsing in PEXEnvironment.can_add (#965)
• Split Pex resolve API. (#970)
• Add a --local mode for packaging the Pex PEX. (#971)
• Constrain the virtualenv version used by tox. (#968)
• Improve Pex packaging. (#961)
• Make the interpreter cache deterministic. (#960)
• Fix deprecation warning for rU mode (#956)
• Fix runtime resolve error message generation. (#955)
• Kill dead code. (#954)

pex 2.1.9

---

2.1.9

This release introduces the ability to copy requirements from an existing PEX into a new one.

This can greatly speed up repeatedly creating a PEX when no requirements have changed.
A build tool (such as Pants) can create a "requirements PEX" that contains just a static
set of requirements, and build a final PEX on top of that, without having to re-run pip
to resolve requirements.

• Support for copying requirements from an existing pex. (#948)

pex 2.1.8

---

2.1.8

This release brings enhanced performance when using the Pex CLI or API to resolve requirements and
improved performance for many PEXed applications when specifying the --unzip option. PEXes built
with --unzip will first unzip themselves into the Pex cache if not unzipped there already and
then re-execute themselves from there. This can improve startup latency. Pex itself now uses this
mode in our PEX release.

• Better support unzip mode PEXes. (#941)
• Support an unzip toggle for PEXes. (#939)
• Ensure the interpreter path is a file (#938)
• Cache pip.pex. (#937)

pex 2.1.7

---

2.1.7

This release brings more robust control of the Pex cache (PEX_ROOT).

The --cache-dir setting is deprecated in favor of build time control of the cache location with
--pex-root and new support for control of the cache's runtime location with --runtime-pex-root
is added. As in the past, the PEX_ROOT environment variable can still be used to control the
cache's runtime location.

Unlike in the past, the Pex PEX
we release can now also be controlled via the PEX_ROOT environment variable. Consult the CLI help
for --no-strip-pex-env to find out more.

• Sanitize PEX_ROOT handling. (#929)
• Fix PEX_* env stripping and allow turning off. (#932)
• Remove second urllib import from compatibility (#931)
• Adding --runtime-pex-root option. (#780)
• Improve interpreter not found error messages. (#928)
• Add detail in interpreter selection error message. (#927)
• Respect Requires-Python in PEXEnvironment. (#923)
• Pin our tox version in CI for stability. (#924)

pex 2.1.6

---

2.1.6

This is a hotfix release that fixes a bug in the code that exposes vendored dists.

• Don't delete the root init.py when devendoring. (#915)
• Remove unused Interpreter.clear_cache. (#911)

pex 2.1.5

---

2.1.5

• Silence pip warnings about Python 2.7. (#908)
• Kill Pip.spawn_install_wheel overwrite arg. (#907)
• Show pex-root from env as default in help output (#901)

pex 2.1.4

---

2.1.4

This release fixes the hermeticity of pip resolver executions when the
resolver is called via the Pex API in an environment with PYTHONPATH
set.

• readme: adding a TOC (#900)
• Fix Pex resolver API PYTHONPATH hermeticity. (#895)
• Fixup resolve debug rendering. (#894)
• Convert bdist_pex tests to explicit cmdclass. (#897)

pex 2.1.3

---

2.1.3

This release fixes a performance regression in which pip
would re-tokenize --find-links pages unnecessarily.
The parsed pages are now cached in a pip patch that has
also been submitted upstream.

• Revendor pip (#890)
• Add a clear_cache() method to PythonInterpreter. (#885)
• Error eagerly if an interpreter binary doesn't exist. (#886)
