 ## Methods

@@ -46,68 +43,40 @@ The `crashReporter` module has the following methods:
 ### `crashReporter.start(options)`

 * `options` Object
+  * `companyName` String
  * `submitURL` String - URL that crash reports will be sent to as POST.
  * `productName` String (optional) - Defaults to `app.name`.
-  * `companyName` String (optional) _Deprecated_ - Deprecated alias for
-    `{ globalExtra: { _companyName: ... } }`.
-  * `uploadToServer` Boolean (optional) - Whether crash reports should be sent
-    to the server. If false, crash reports will be collected and stored in the
-    crashes directory, but not uploaded. Default is `true`.
-  * `ignoreSystemCrashHandler` Boolean (optional) - If true, crashes generated
-    in the main process will not be forwarded to the system crash handler.
-    Default is `false`.
-  * `rateLimit` Boolean (optional) _macOS_ _Windows_ - If true, limit the
-    number of crashes uploaded to 1/hour. Default is `false`.
-  * `compress` Boolean (optional) _macOS_ _Windows_ - If true, crash reports
-    will be compressed and uploaded with `Content-Encoding: gzip`. Not all
-    collection servers support compressed payloads. Default is `false`.
-  * `extra` Record<String, String> (optional) - Extra string key/value
-    annotations that will be sent along with crash reports that are generated
-    in the main process. Only string values are supported. Crashes generated in
-    child processes will not contain these extra
-    parameters to crash reports generated from child processes, call
-    [`addExtraParameter`](#crashreporteraddextraparameterkey-value) from the
-    child process.
-  * `globalExtra` Record<String, String> (optional) - Extra string key/value
-    annotations that will be sent along with any crash reports generated in any
-    process. These annotations cannot be changed once the crash reporter has
-    been started. If a key is present in both the global extra parameters and
-    the process-specific extra parameters, then the global one will take
-    precedence. By default, `productName` and the app version are included, as
-    well as the Electron version.
+  * `uploadToServer` Boolean (optional) - Whether crash reports should be sent to the server. Default is `true`.
+  * `ignoreSystemCrashHandler` Boolean (optional) - Default is `false`.
+  * `extra` Record<String, String> (optional) - An object you can define that will be sent along with the
+    report. Only string properties are sent correctly. Nested objects are not
+    supported. When using Windows, the property names and values must be fewer than 64 characters.
+  * `crashesDirectory` String (optional) - Directory to store the crash reports temporarily (only used when the crash reporter is started via `process.crashReporter.start`).

-This method must be called before using any other `crashReporter` APIs. Once
-initialized this way, the crashpad handler collects crashes from all
-subsequently created processes. The crash reporter cannot be disabled once
-started.
+You are required to call this method before using any other `crashReporter` APIs
+and in each process (main/renderer) from which you want to collect crash reports.
+You can pass different options to `crashReporter.start` when calling from different processes.

-This method should be called as early as possible in app startup, preferably
-before `app.on('ready')`. If the crash reporter is not initialized at the time
-a renderer process is created, then that renderer process will not be monitored
-by the crash reporter.
+**Note** Child processes created via the `child_process` module will not have access to the Electron modules.
+Therefore, to collect crash reports from them, use `process.crashReporter.start` instead. Pass the same options as above
+along with an additional one called `crashesDirectory` that should point to a directory to store the crash
+reports temporarily. You can test this out by calling `process.crash()` to crash the child process.

-**Note:** You can test out the crash reporter by generating a crash using
-`process.crash()`.
+**Note:** If you need send additional/updated `extra` parameters after your
+first call `start` you can call `addExtraParameter` on macOS or call `start`
+again with the new/updated `extra` parameters on Linux and Windows.

-**Note:** If you need to send additional/updated `extra` parameters after your
-first call `start` you can call `addExtraParameter`.

-must be at most 39 bytes long, and values must be no longer than 127 bytes.
-Keys with names longer than the maximum will be silently ignored. Key values
-longer than the maximum length will be truncated.
-
-**Note:** Calling this method from the renderer process is deprecated.
+**Note:** On macOS and windows, Electron uses a new `crashpad` client for crash collection and reporting.
+If you want to enable crash reporting, initializing `crashpad` from the main process using `crashReporter.start` is required

-### Types of Breaking Changes
+## `FIXME` comments

-This document uses the following convention to categorize breaking changes:
-
- **API Changed:** An API was changed in such a way that code that has not been updated is guaranteed to throw an exception.
- **Behavior Changed:** The behavior of Electron has changed, but not in such a way that an exception will necessarily be thrown.
- **Default Changed:** Code depending on the old default may break, not necessarily throwing an exception. The old behavior can be restored by explicitly specifying the value.
- **Deprecated:** An API was marked as deprecated. The API will continue to function, but will emit a deprecation warning, and will be removed in a future release.
- **Removed:** An API or feature was removed, and is no longer supported by Electron.

- `crashReporter.getLastCrashReport`
- `crashReporter.getUploadedReports`
- `crashReporter.getUploadToServer`

-They should be called only from the main process.

-
-The `companyName` argument to `crashReporter.start()`, which was previously
-required, is now optional, and further, is deprecated. To get the same
-behavior in a non-deprecated way, you can pass a `companyName` value in
-`globalExtra`.

-// Deprecated in Electron 10
-crashReporter.start({ companyName: 'Umbrella Corporation' })
-// Replace with
-crashReporter.start({ globalExtra: { _companyName: 'Umbrella Corporation' } })

-### Deprecated: `crashReporter.getCrashesDirectory()`
-
-The `crashReporter.getCrashesDirectory` method has been deprecated. Usage
-should be replaced by `app.getPath('crashDumps')`.

- `crashReporter.getUploadToServer`

Sesh Sadasivam	c8273e375c	fix: add Chromium patch to fix RTL window buttons (#22016 ) Classes that inherit from `NSThemeFrame` seem to show window buttons in the incorrect position when the primary MacOS language is set to an RTL (right-to-left) language like Arabic or Hebrew. The fix in this commit mirrors that of `tabbed_browser_window.mm` (https://chromium-review.googlesource.com/c/chromium/src/+/562603/10/chrome/browser/ui/cocoa/tabbed_browser_window.mm#88). This change should be upstreamed, and then this patch can be removed.	2020-02-06 16:14:18 -05:00
