Meteor + Mongo Transactions

v1.x [WILL NEED HELP]

  • Explore Operational Transform options
  • Look into support for {multi: true}
  • Support for upsert
  • Possible support for locking documents used in pending transactions

v1.0 [PLANNED]

  • Refactor and document code for better maintainability
  • Sufficient test coverage and security audit

v0.9 [PLANNED]

  • Add/improve support for other/existing mongo operators

v0.8.5

  • Fix for an issue where transactions with overridePermissionCheck = true that were successful on the server, but unsuccessful when simulated on the client, left the client in a bad state

v0.8.4

  • Merged PR that retries repair of transactions that were being repaired during an app crash, when retryFailedRepairs is true

v0.8.3

  • Changed states of items on a transaction and the transaction state itself to rolledBack when the repairMode is set to rollback (it was previously undone, which was deceptive and not what we're after - i.e. removing the transaction from the mix completely)
  • Added a second parameter (retryFailedRepairs - boolean) to the function tx._repairAllIncomplete(mode, retryFailedRepairs), in case anyone wants to force another attempt to repair transactions that have have already failed to be repaired

v0.8.2

  • Accept an object literal as first param tx.start calls to provide an options hash; previously only accepted string for first param (description text) and object literal for second param (options hash). One of the fields of the options hash can be description

v0.8.1

  • Options to rethrow exceptions caught during a commit (#72)
  • Fixes for removed documents not being saved properly (#73)
  • Fix for hard removed documents that prevented them from being re-removed after a transaction (#74)
  • Fixed a part of code that wasn't refactored properly for multiple transactions (#76)
  • Upserts throw explicit exceptions (#78)
  • You can now pass a value for rethrowCommitError, forceCommitBeforeStart, useExistingTransaction (all false by default) in the options hash when starting a transaction that will auto-commit

v0.8.0

  • Refactored package internals to make it more robust when multiple transactions are happening concurrently

v0.7.17

  • Fixed a bug with logging (introduced in last update) which broke a few tests that went unnoticed
  • Fixed bug in which Collection.insert was wrongly mutating the newDoc object being inserted
  • Added tx.getContext method
  • Added tx.mergeContext and tx.setContextPathValue methods for lodash users
  • Changed absolute to relative symlink from the test app to the transactions package so everyone can run tests

v0.7.16

  • Fixed the bug introduced with the client idleTimeout feature (i.e. a long wait for the server to process a committed queue of actions leads to a client-initiated rollback)
  • Updated weak dependency on aldeed:collection2 package to version 2.10.0 (from 2.9.0)

v0.7.15

  • Added forceCommitBeforeStart option as a means of strictly keeping the app in a good state (at the cost of potentially messy data if there are bugs in the app)
  • Made the client time out and auto-rollback if a transaction is open longer than a certain (configurable) number of milliseconds

v0.7.14

  • Added check package as a dependency

v0.7.13

  • Closes #57 where write operations were async when they should have been sync

v0.7.12

  • Fixes a bug with the ordering of actions when trying to repair a broken commit and removes SimpleSchema.debug = true;

v0.7.11

  • Fixes a bug with $addToSet and $pull where inverses were not being recorded correctly

v0.7.10

  • Restores a semblance of latency compensation in some cases

v0.7.9

  • Fixes a bug where an error is thrown unnecessarily on an empty transaction

v0.7.8

  • Closes issue #49 (insert callbacks with collection2 not working) and #50 (undo of $set modifiers with multiple fields not restoring previous state correctly)

v0.7.7

  • Closes an issue (#48) in which Meteor.settings isn't defined for android builds and error gets thrown

v0.7.6

  • Closes an issue (#47) related to security, where transactions originating on the client could override the tx.checkPermission function on the server

v0.7.5

  • Fixes for a number of issues, the chief one being a broken rollback mechanism
  • A small change in which auto committed insert transactions are not processed client side, but are sent to the server for writes, like other transactions in tx.start() ... tx.commit() blocks, removing the need for allow/deny rules for inserts

v0.7.0

  • First release using new storage format for transactions and having db state recovery options

v0.6.21

  • Last stable(ish) release using naive/optimistic transactions with no db state recoverability
