From 4e3a0e2fc7c1c5779367dc5682505c65239a0fd5 Mon Sep 17 00:00:00 2001 From: Geri Jennings Date: Wed, 6 Feb 2019 14:39:41 -0500 Subject: [PATCH 01/10] Initial conversion to supply buildpack This commit is the first step toward converting toward a supply buildpack. Known issues: - Running cf create-buildpack fails because the bin/compile script is missing, but it's not clear what this (deprecated) script is supposed to do - The bin/supply script is actually only allowed to modify the deps and index directories, and it's now set to modify the build directory. That will have to be updated, and we will need to determine how the retrieve secrets script will get run by the app. We may also need to update how the bp-supplied scripts / conjur-env look for secrets.yml, if they are no longer working from the same directory as the app dir. --- bin/decorate | 21 ----------------- bin/detect | 23 ++++++++++++++++--- bin/{compile => supply} | 10 +++++--- ci/docker-compose.yml | 2 +- ci/features/buildpackless.feature | 2 +- ci/features/decorate.feature | 15 ------------ ci/features/detect.feature | 17 ++++++++++---- ci/features/profile_d.feature | 2 +- ci/features/step_definitions/common_steps.rb | 4 ++-- .../{compile.feature => supply.feature} | 6 ++--- 10 files changed, 48 insertions(+), 54 deletions(-) delete mode 100755 bin/decorate rename bin/{compile => supply} (68%) delete mode 100755 ci/features/decorate.feature rename ci/features/{compile.feature => supply.feature} (64%) diff --git a/bin/decorate b/bin/decorate deleted file mode 100755 index 08699ea..0000000 --- a/bin/decorate +++ /dev/null @@ -1,21 +0,0 @@ -#!/bin/bash -e -# bin/decorate - -#export VCAP_SERVICES=' -#{ -# "cyberark-conjur": [{ -# "credentials": { -# "appliance_url": "https://conjur.myorg.com/", -# "authn_api_key": "2389fh3hf9283niiejwfhjsb83ydbn23u", -# "authn_login": "3F20D12E-A470-4B7B-8778-C8885769887F", -# "account": "brokered-services", -# "ssl_certificate": "-----BEGIN CERTIFICATE----...", -# "version": 4 -# } -# }] -#} -#' - -BUILD_DIR=$1 - -[ -f $BUILD_DIR/secrets.yml ] && [[ true = $(echo $VCAP_SERVICES | jq 'has("cyberark-conjur")') ]] || exit 1 diff --git a/bin/detect b/bin/detect index c5b704f..08699ea 100755 --- a/bin/detect +++ b/bin/detect @@ -1,4 +1,21 @@ #!/bin/bash -e -# bin/detect -# We are a decorator, not a buildpack, so we always decline to build -exit 1 +# bin/decorate + +#export VCAP_SERVICES=' +#{ +# "cyberark-conjur": [{ +# "credentials": { +# "appliance_url": "https://conjur.myorg.com/", +# "authn_api_key": "2389fh3hf9283niiejwfhjsb83ydbn23u", +# "authn_login": "3F20D12E-A470-4B7B-8778-C8885769887F", +# "account": "brokered-services", +# "ssl_certificate": "-----BEGIN CERTIFICATE----...", +# "version": 4 +# } +# }] +#} +#' + +BUILD_DIR=$1 + +[ -f $BUILD_DIR/secrets.yml ] && [[ true = $(echo $VCAP_SERVICES | jq 'has("cyberark-conjur")') ]] || exit 1 diff --git a/bin/compile b/bin/supply similarity index 68% rename from bin/compile rename to bin/supply index 7e07779..2100708 100755 --- a/bin/compile +++ b/bin/supply @@ -1,12 +1,16 @@ #!/bin/bash -e -# bin/compile - -echo "[cyberark-conjur-buildpack]: compiling" +# bin/supply BUILD_DIR=$1 +CACHE_DIR=$2 +DEPS_DIR=$3 +INDEX=$4 + BIN_DIR=$(cd $(dirname $0);

The Parser, on the contrary, -// is a straightforward implementation of a recursive-descendant parser (or, -// LL(1) parser, as it is usually called). -// -// Actually there are two issues of Scanning that might be called "clever", the -// rest is quite straightforward. The issues are "block collection start" and -// "simple keys". Both issues are explained below in details. -// -// Here the Scanning step is explained and implemented. We start with the list -// of all the tokens produced by the Scanner together with short descriptions. -// -// Now, tokens: -// -// STREAM-START(encoding) # The stream start. -// STREAM-END # The stream end. -// VERSION-DIRECTIVE(major,minor) # The '%YAML' directive. -// TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive. -// DOCUMENT-START # '---' -// DOCUMENT-END # '...' -// BLOCK-SEQUENCE-START # Indentation increase denoting a block -// BLOCK-MAPPING-START # sequence or a block mapping. -// BLOCK-END # Indentation decrease. -// FLOW-SEQUENCE-START # '[' -// FLOW-SEQUENCE-END # ']' -// BLOCK-SEQUENCE-START # '{' -// BLOCK-SEQUENCE-END # '}' -// BLOCK-ENTRY # '-' -// FLOW-ENTRY # ',' -// KEY # '?' or nothing (simple keys). -// VALUE # ':' -// ALIAS(anchor) # '*anchor' -// ANCHOR(anchor) # '&anchor' -// TAG(handle,suffix) # '!handle!suffix' -// SCALAR(value,style) # A scalar. -// -// The following two tokens are "virtual" tokens denoting the beginning and the -// end of the stream: -// -// STREAM-START(encoding) -// STREAM-END -// -// We pass the information about the input stream encoding with the -// STREAM-START token. -// -// The next two tokens are responsible for tags: -// -// VERSION-DIRECTIVE(major,minor) -// TAG-DIRECTIVE(handle,prefix) -// -// Example: -// -// %YAML 1.1 -// %TAG ! !foo -// %TAG !yaml! tag:yaml.org,2002: -// --- -// -// The correspoding sequence of tokens: -// -// STREAM-START(utf-8) -// VERSION-DIRECTIVE(1,1) -// TAG-DIRECTIVE("!","!foo") -// TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:") -// DOCUMENT-START -// STREAM-END -// -// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole -// line. -// -// The document start and end indicators are represented by: -// -// DOCUMENT-START -// DOCUMENT-END -// -// Note that if a YAML stream contains an implicit document (without '---' -// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be -// produced. -// -// In the following examples, we present whole documents together with the -// produced tokens. -// -// 1. An implicit document: -// -// 'a scalar' -// -// Tokens: -// -// STREAM-START(utf-8) -// SCALAR("a scalar",single-quoted) -// STREAM-END -// -// 2.
