Subject: [PATCH 0011/1463] IGNITE-7944: Disconnected client node tries to send
 JOB_CANCEL message. Applied fix: - Skip sending message if client
 disconnected; - Throw IgniteCheckedException if a client node is disconnected
 and communication client is null. This closes #3737.

-/**
- * This class encapsulates convenient way for creating computations chain for distributed model training.
- * Chain is meant in the sense that output of each non-final computation is fed as input to next computation.
- * Chain is basically a bi-function from context and input to output, context is separated from input

Subject: [PATCH 0064/1463] IGNITE-8200 Web Console: Override clonedCluster in
 cluster-edit-form if caches or models have changed.     This improves interop
 with "import from DB" feature, which might update caches/models of cluster
 currently opened for editing.     The import dialog works as a separate
 state, so the form change detection mechanism ensures that any changes to the
 original     cluster are safe and won't interfere with changes made by user
 in cluster edit form.

(cherry picked from commit 7731669)

Subject: [PATCH 0125/1463] IGNITE-8242: Remove method
 GAGridUtils.getGenesForChromosome() as problematic when Chromosome contains
 duplicate genes. GAGridUtils.getGenesInOrderForChromosome() will be used
 instead.

this closes #3813

  * --enable-core - build Ignite core library. Enabled by default.
+ * --enable-thin-client - build thin client library. Enabled by default.
  * --enable-node - build stand-alone node executable. Enabled by default.
  
 If you only need to build ODBC driver and do not want to build anything else you may just
 use configure script with the following arguments:
- ./configure --enable-odbc --disable-core --disable-node
+ ./configure --enable-odbc --disable-core --disable-thin-client --disable-node
 
 With the config like that you should not have any ignite dependencies as jvm.dll installed
 to build ODBC driver.
+ 
+Similarly if you only want to build only thin client you may use configure script with
+the following arguments:
+ ./configure --disable-core --disable-node
 
 NOTE: You may want to use "make install" command to install Ignite libraries and headers
 for your operation system. Note however that this action may require superuser privileges.

Subject: [PATCH 0451/1463] IGNITE-8927: SQL: correct handling of LOST
 partitions on mapper side. Note that for local queries this doesn't work
 still because partition state is not checked (see IGNITE-7039). This closes
 #4679.

Subject: [PATCH 0488/1463] IGNITE-8552: SQL: mapped DATE data type to
 java.util.Date in DDL processor. This allows to use DATE type as PK from DDL
 as well as significantly improves performance of DATE column processing if
 parent table was created from DDL. This closes #4692.

Subject: [PATCH 0509/1463] Revert "IGNITE-8552: SQL: mapped DATE data type to
 java.util.Date in DDL processor. This allows to use DATE type as PK from DDL
 as well as significantly improves performance of DATE column processing if
 parent table was created from DDL. This closes #4692."

This reverts commit 4cd94b11e1ba5b862513e7ceebd91f4353343ec1.

 Requirements
 -------------------------------------
-1. JDK 8 bit for your platform, or newer.
+1. JDK 8 suitable for your platform.
 2. Supported browsers: Chrome, Firefox, Safari, Edge.
-3. Ignite cluster should be started with `ignite-rest-http` module in classpath. For this copy `ignite-rest-http` folder from `libs\optional` to `libs` folder.
-
+3. Ignite cluster should be started with `ignite-rest-http` module in classpath.
+ For this copy `ignite-rest-http` folder from `libs\optional` to `libs` folder.
 
 How to run
 -------------------------------------
 1. Unpack ignite-web-console-x.x.x.zip to some folder.
 2. Change work directory to folder where Web Console was unpacked.
 3. Start ignite-web-console-xxx executable for you platform:
-	For Linux: ignite-web-console-linux
-	For MacOS: ignite-web-console-macos
-	For Windows: ignite-web-console-win.exe
+    For Linux: `sudo ./ignite-web-console-linux`
+    For macOS: `sudo ./ignite-web-console-macos`
+    For Windows: `ignite-web-console-win.exe`
 
-Note: on Linux and Mac OS X `root` permission is required to bind to 80 port, but you may always start Web Console on another port if you don't have such permission.
+NOTE: For Linux and macOS `sudo` required because non-privileged users are not allowed to bind to privileged ports (port numbers below 1024).
 
 4. Open URL `localhost` in browser.
 5. Login with user `admin@admin` and password `admin`.
 6. Start web agent from folder `web agent`. For Web Agent settings see `web-agent\README.txt`.
-Cluster URL should be specified in `web-agent\default.properties` in `node-uri` parameter.
+
+NOTE: Cluster URL should be specified in `web-agent\default.properties` in `node-uri` parameter.
 
 Technical details
 -------------------------------------
 1. Package content:
-	`libs` - this folder contains Web Console and MongoDB binaries.
-	`user_data` - this folder contains all Web Console data (registered users, created objects, ...) and should be preserved in case of update to new version.
-2. Package already contains MongoDB for Mac OS X, Windows, RHEL, CentOs and Ubuntu on other platforms MongoDB will be downloaded on first start. MongoDB executables will be downloaded to `libs\mogodb` folder.
+    `libs` - this folder contains Web Console and MongoDB binaries.
+    `user_data` - this folder contains all Web Console data (registered users, created objects, ...) and
+     should be preserved in case of update to new version.
+    `web-agent` - this folder contains Web Agent.
+2. Package already contains MongoDB for macOS, Windows, RHEL, CentOs and Ubuntu on other platforms MongoDB will be downloaded on first start. MongoDB executables will be downloaded to `libs\mogodb` folder.
 3. Web console will start on default HTTP port `80` and bind to all interfaces `0.0.0.0`.
 3. To bind Web Console to specific network interface:
-	On Linux: `./ignite-web-console-linux --server:host 192.168.0.1`
-	On Windows: `ignite-web-console-win.exe --server:host 192.168.0.1`
+    On Linux: `./ignite-web-console-linux --server:host 192.168.0.1`
+    On macOS: `sudo ./ignite-web-console-macos --server:host 192.168.0.1`
+    On Windows: `ignite-web-console-win.exe --server:host 192.168.0.1`
 4. To start Web Console on another port, for example `3000`:
-	On Linux: `sudo ./ignite-web-console-linux --server:port 3000`
-	On Windows: `ignite-web-console-win.exe --server:port 3000`
+    On Linux: `sudo ./ignite-web-console-linux --server:port 3000`
+    On macOS: `./ignite-web-console-macos --server:port 3000`
+    On Windows: `ignite-web-console-win.exe --server:port 3000`
 
 All available parameters with defaults:
-	Web Console host:           --server:host 0.0.0.0
-	Web Console port:           --server:port 80
-	Enable HTTPS:               --server:ssl false
-	HTTPS key:                  --server:key "serve/keys/test.key"
-	HTTPS certificate:          --server:cert "serve/keys/test.crt"
-	HTTPS passphrase:           --server:keyPassphrase "password"
-	MongoDB URL:                --mongodb:url mongodb://localhost/console
-	Mail service:               --mail:service "gmail"

+
+Sample usage:
+    `ignite-web-console-win.exe --mail:auth:user "my_user@gmail.com"  --mail:auth:pass "my_password"`
+
+Advanced configuration of SMTP for Web Console.
+-------------------------------------
+1. Create sub-folder "config" in folder with Web Console executable.
+2. Create in config folder file "settings.json".
+3. Specify SMTP settings in settings.json (updating to your specific names and passwords):
+
+Sample "settings.json":
+{
+    "mail": {
+        "service": "gmail",
+        "greeting": "My Company Greeting",
+        "from": "My Company Web Console <some_name@gmail.com>",
+        "sign": "Kind regards,<br>My Company Team",
+        "auth": {
+            "user": "some_name@gmail.com",
+            "pass": "my_password"
+        }
+    }
+}
+
+Web Console sends e-mails with help of NodeMailer: https://nodemailer.com.
+
+Documentation available here:
+   https://nodemailer.com/smtp
+   https://nodemailer.com/smtp/well-known
+
+In case of non GMail SMTP server it may require to change options in "settings.json" according to NodeMailer documentation.

Subject: [PATCH 0551/1463] IGNITE-9528 Web Console: Fixed handling of
 "LOAD_COMPLETE_CONFIGURATION_ERR" action in PageConfigure service.   
 Previous implementation used to throw a complete store message instead of an
 error it wraps.    Also updated clusterServiceConfiguration generator to fail
 gracefully if some of caches do not exist.

+Apache Ignite Direct IO Module
+-------------------------------------
+
+Apache Ignite Direct IO is plugin, which provides page store with ability to write and read cache partitions
+in O_DIRECT mode.
+
+OS gets the data and stores it in a file buffer cache. Similarly, for every write operation,
+the OS first writes the data in a cache and then transfers to the disk. To eliminate this process you can enable
+Direct I/O in which case the data is read and written directly from/to the disk bypassing the file buffer cache.
+
+Direct I/O plugin in Ignite is used for the checkpointing process where the dirty pages in RAM are written to the disk.
+
+Importing Direct I/O Pluging In Maven Project
+-------------------------------------
+
+If you are using Maven to manage dependencies of your project, you can add Direct IO Module
+dependency like this (replace '${ignite.version}' with actual Ignite version you are
+interested in):
+
+<project xmlns="http://maven.apache.org/POM/4.0.0"
+    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
+                        http://maven.apache.org/xsd/maven-4.0.0.xsd">
+    ...
+    <dependencies>
+        ...
+        <dependency>
+            <groupId>org.apache.ignite</groupId>
+            <artifactId>ignite-direct-io</artifactId>
+            <version>${ignite.version}</version>
+        </dependency>
+        ...
+    </dependencies>
+    ...
+</project>
+
+Importing Direct I/O Pluging In Gradle Project
+-------------------------------------
+For gradle you can add compile dependency, where igniteVersion is actual Ignite version:
+
+compile group: 'org.apache.ignite', name: 'ignite-direct-io', version: igniteVersion
+
+Additional setup is not required. Once plugin is available in classpath, it will be used for Durable Memory IO.
+
+-------------------------------------
+See more information in Apache Ignite documentation:
+https://apacheignite.readme.io/docs/durable-memory-tuning#section-enabling-direct-i-o
+
+and description of internal desing can be found in Wiki:
+https://cwiki.apache.org/confluence/display/IGNITE/Ignite+Persistent+Store+-+under+the+hood#IgnitePersistentStore-underthehood-DirectI/O

+/**
+ * An object that measures elapsed time in nanoseconds. It is useful to measure elapsed time using
+ * this class instead of direct calls to {@link System#nanoTime} for a few reasons:
+ *
+ * <ul>
+ *   <li>An alternate time source can be substituted, for testing or performance reasons.
+ *   <li>As documented by {@code nanoTime}, the value returned has no absolute meaning, and can only
+ *       be interpreted as relative to another timestamp returned by {@code nanoTime} at a different
+ *       time. {@code Stopwatch} is a more effective abstraction because it exposes only these
+ *       relative values, not the absolute ones.
+ * </ul>
+ *
+ * <p>Basic usage:
+ *
+ * <pre>{@code
+ * Stopwatch stopwatch = Stopwatch.createStarted();
+ * doSomething();
+ * stopwatch.stop(); // optional
+ *
+ * Duration duration = stopwatch.elapsed();
+ *
+ * log.info("time: " + stopwatch); // formatted string like "12.3 ms"
+ * }</pre>
+ *
+ * <p>Stopwatch methods are not idempotent; it is an error to start or stop a stopwatch that is
+ * already in the desired state.
+ *
+ * <p>When testing code that uses this class, use {@link #createUnstarted(IgniteTicker)} or {@link
+ * #createStarted(IgniteTicker)} to supply a fake or mock ticker. This allows you to simulate any valid
+ * behavior of the stopwatch.
+ *
+ * <p><b>Note:</b> This class is not thread-safe.
+ *
+ * <p><b>Warning for Android users:</b> a stopwatch with default behavior may not continue to keep
+ * time while the device is asleep. Instead, create one like this:
+ *
+ * <pre>{@code
+ * Stopwatch.createStarted(
+ *      new Ticker() {
+ *        public long read() {
+ *          return android.os.SystemClock.elapsedRealtimeNanos();
+ *        }
+ *      });
+ * }</pre>

Subject: [PATCH 0798/1463] IGNITE-9809 Web console: more minor fixes - Fixes
 #4972.

Update TestCafe to 0.22.0.
Update confirmation E2E selectors so these work when multiple modals are opened.
Update reduxDevtoolsIntegration.js so it doesn't crash when there's a Promise in action payload.

+                  Also at this moment node3 is started;
+                - when node0 receives this NodeFailed it fails (because special SPI throws an exception) and stops;

+                  node1's special SPI also throws an exception so it goes down as well;

+                  they see each other and are able to send join requests to each other back and forth.
+
+            The whole purpose of the test is to verify that these two nodes won't stuck in CONNECTING state forever

Subject: [PATCH 1143/1463] IGNITE-11767 Clean up GridDhtPartitionsFullMessage
 when not needed, do not hold decompressed partsSizes in field.

Since uncompression of partsSizes is de-parallelized, PME might be slightly slower while consuming way less Heap.

+ * Allows to execute callback when a set of operations will be completed. Also has an execution counter,

+ * <pre>{@code
+ *     GridCountDownCallback countDownCb = new GridCountDownCallback(

+ *     //doSomething() will be executed after counter reaches 0
+ *     for (int i = 0; i < n; i++)
+ *         new Thread(() -> countDownCb.countDown()).start();

+ *         n/2                    //execution threshold is initiated with n/2
+ *     );
+ *
+ *     //a half of calls of countDown() increase execution counter, so it reaches threshold and callback executes.
+ *     //doSomething() will be executed after n threads will perform countDown()
+ *     for (int i = 0; i < n; i++)

+/**
+ * Update counter implementation used for transactional cache groups in persistent mode.
+ * <p>
+ * Implements new partition update counter flow to avoid situations when:
+ * <ol>
+ *     <li>update counter could be incremented and persisted while corresponding update is not recorded to WAL.</li>
+ *     <li>update counter could be prematurely incremented causing missed rebalancing.</li>
+ * </ol>
+ * All these situations are sources of partitions desync.
+ * <p>
+ * Below a short description of new flow:
+ * <ol>
+ *     <li>Update counter is <i>reserved</i> for each update in partition on tx prepare phase (which always happens
+ *     on primary partition owner). Reservation causes HWM increment.</li>
+ *     <li>Reserved counter values are propagated on backup nodes and stored in backup transactions.</li>
+ *     <li>On commit reserved counters are assigned to cache entries.</li>
+ *     <li>LWM is incremented ONLY after corresponding WAL data record for each entry was written.</li>
+ *     <li>In case of rollback (manual or during tx recovery on node failure) reserved updates are also applied and
+ *     logged to WAL using {@link RollbackRecord} for further recovery purposes.</li>
+ * </ol>

Subject: [PATCH 1459/1463] GG-21615 .NET: Fix StreamTransformer ignoring
 duplicate keys

* Root cause: `StreamTransformer` used `InvokeAll`, while in Java it is `Invoke` in a loop, causing different semantics.
* Related issue: local processor allocation is not used, causing performance degradation for `Invoke` calls on local cache entries (which is exactly what's going on with `StreamTransformer`)
