From 3dbb4874881aa79bfe03cc6c4ae1c5771998708f Mon Sep 17 00:00:00 2001 From: Dom Date: Mon, 18 Sep 2017 11:03:32 +0100 Subject: [PATCH] Merge development (#39) * add DropAllIndexes() method (#25) Create a new method to drop all the indexes of a collection in a single call * readme: credit @feliixx for #25 (#26) * send metadata during handshake (#28) fix [#484](https://github.com/go-mgo/mgo/issues/484) Annotate connections with metadata provided by the connecting client. informations send: { "aplication": { // optional "name": "myAppName" } "driver": { "name": "mgo", "version": "v2" }, "os": { "type": runtime.GOOS, "architecture": runtime.GOARCH } } to set "application.name", add `appname` param in options of string connection URI, for example : "mongodb://localhost:27017?appname=myAppName" * Update README to add appName (#32) * docs: elaborate on what appName does * readme: add appName to changes * add method CreateView() (#33) Fix #30. Thanks to @feliixx for the time and effort. * readme: credit @feliixx in the README (#36) * Don't panic on indexed int64 fields (#23) * Stop all db instances after tests (#462) If all tests pass, the builds for mongo earlier than 2.6 are still failing. Running a clean up fixes the issue. * fixing int64 type failing when getting indexes and trying to type them * requested changes relating to case statement and panic * Update README.md to credit @mapete94. * tests: ensure indexed int64 fields do not cause a panic in Indexes() See: * https://github.com/globalsign/mgo/pull/23 * https://github.com/go-mgo/mgo/issues/475 * https://github.com/go-mgo/mgo/pull/476 * Add collation option to collection.Create() (#37) - Allow specifying the default collation for the collection when creating it. - Add some documentation to query.Collation() method. fix #29 * Test against MongoDB 3.4.x (#35) * test against MongoDB 3.4.x * tests: use listIndexes to assert index state for 3.4+ * make test pass against v3.4.x - skip `TestViewWithCollation` because of SERVER-31049, cf: https://jira.mongodb.org/browse/SERVER-31049 - add versionAtLeast() method in init.js script to better detect server version fixes #31 --- .travis.yml | 14 +- README.md | 8 +- cluster.go | 17 +- cluster_test.go | 18 ++ harness/daemons/.env | 42 +++- harness/daemons/cfg1/run | 3 +- harness/daemons/cfg2/run | 3 +- harness/daemons/cfg3/run | 1 + harness/daemons/s1/run | 2 +- harness/daemons/s2/run | 2 +- harness/daemons/s3/run | 2 +- harness/mongojs/init.js | 37 +++- session.go | 139 +++++++++--- session_internal_test.go | 24 ++ session_test.go | 463 ++++++++++++++++++++++++++++++++++----- 15 files changed, 667 insertions(+), 108 deletions(-) create mode 100644 session_internal_test.go diff --git a/.travis.yml b/.travis.yml index 28d3c5cf4..430844718 100644 --- a/.travis.yml +++ b/.travis.yml @@ -2,29 +2,22 @@ language: go go_import_path: github.com/globalsign/mgo -addons: -
