The termux plugins should use this library instead of hardcoding "com.termux" values in their source code.
The library can be included as a dependency by plugins and third party apps by including the following line in the build.gradle where x.xxx is the version number, once its published.
`implementation 'com.termux:termux-shared:x.xxx'`
The `TermuxConstants` class has been updated to `v0.17.0`, `TermuxPreferenceConstants` to `v0.9.0` and `TermuxPropertyConstants` to `v0.6.0`. Check their Changelog sections for info on changes.
Some typos and redundant code has also been fixed.
Now whenever the Termux app crashes, the crash report (stacktrace, app and device info) will be logged to ~/crash_log.md file. When the user will reopen the app, a notification will be shown which when clicked will show the crash report content in the ReportActivity. The activity will have important links like email, reddit, github issues of termux app and packages at which the user can optionally report an issue if necessary after copying the crash report text. The ~/crash_log.md file will be moved to ~/crash_log-backup.md so that a notification is not shown again on next startup and can be viewed again via SAF, etc.
This will allow reports for bugs that are submitted to have complete and useful info, specially in markdown format, making lives of devs a tad bit easier. Also more bugs that are rare might be submitted since users will have the info to report with and know where to report at.
ToDo:
- The TermuxConstants.TERMUX_SUPPORT_EMAIL_URL needs to be updated with a valid support email once its set up. The TermuxUtils.getReportIssueMarkdownString() function currently also has "email" lines commented out which will need to be uncommented.
- Currently, crashes will only be handled for the main app thread, other threads will have to manually hooked into where necessary.
This will allow users to control if a notification should be shown with the crash info when app is restarted after a crash
The `TermuxPreferenceConstants` classes has been updated to `v0.8.0`. Check its Changelog section for info on changes.
A lot of utils have been defined now that can be used to safely manage files.
The java java.io.File API has poor support for detecting symlinks including broken symlinks. Android implementation also has issues. Check FileTypes.getFileType() function for more info. For this reason, the UnixFileAttributes and related classes has been ported from AOSP to get file attributes and type.
Some file utils and android versions use google's Guava com.google.common.io.MoreFiles library for managing files, specially for safer directory deletion with SecureDirectoryStream.
Some file utils and android versions use org.apache.commons.io.FileUtils for managing files. The library version used is 2.5 and it must not be incremented for compatibility with android version < 8, otherwise runtime crashes will occur.
- PackageUtils has been added to get various package related info. This will be used to get info based on Context objects instead of using BuildConfig which wouldn't have been available across termux plugins.
- Support for getting Context objects of all termux plugin apps have been added to TermuxUtils.
- Support for showing more details for the app has been added for ReportActivity. This will also allow app info of Termux app to be generated when TermuxUtils.getAppInfoMarkdownString() is called by a termux plugin so that both are shown so that devs/users can more easily detect compatibility issues.
- ReportActivity has been fixed to also include report and device info instead of just the ExecutionCommand info when copying and sharing.
- Moved the generation of markdown for ReportInfo to its own class and added creationTimestamp field.
- Increased markdown headings size for some cases.
Users can toggle the state from Settings -> Keyboard I/O -> Soft Keyboard toggle.
Android phone should also have an internal setting for disabling soft keyboard when a hardware keyboard is connected in Language and Input android settings or from the input mode selection notification, but the above setting will be Termux app specific and will allow soft keyboard to still be shown in other apps.
The `TermuxPreferenceConstants` classes has been updated to `v0.7.0`. Check its Changelog section for info on changes.
If the pending intent is not null, then the errors will be sent back to the caller without notifying the user, since we will let the caller handle the errors himself. They will still be logged in logcat.
However, if "allow-external-apps" is not true, then a flash and notification will be shown forcefully (regardless of "Plugin Execution Errors" toggle state), so that the user knows someone tried to run a command in termux context, since it may be malicious app or imported (tasker) plugin project and not the user himself. If a pending intent is also sent, then its creator is also logged and shown.
Previously, termux only supported getting result of BACKGROUND commands back if they were started via Termux:Tasker plugin. Getting back result of foreground commands was not possible with any way.
Now with RUN_COMMAND intent or Termux:Tasker, the third party apps and users can get the foreground command results as well. Note that by "foreground results" we only mean the session transcript. The session transcript will contain both stdout and stderr combined, basically anything sent to the the pseudo terminal /dev/pts, including PS1 prefixes for interactive sessions. Getting separate stdout and stderr can currently only be done with background commands.
Moreover, with RUN_COMMAND intent, third party apps and users can get the background commands results as well. This means separate extras for stdout and stderr.
The exit code will also be returned for either case.
### RUN_COMMAND intent
The result extras are returned in the TERMUX_SERVICE.EXTRA_PLUGIN_RESULT_BUNDLE bundle via the pending intent received.
The RUN_COMMAND_SERVICE.EXTRA_PENDING_INTENT extra can be used to send the pending intent with which termux should return the result bundle. The pending intent can be received back by the app with an IntentService. Check RunCommandService for reference implementation.
For foreground commands (RUN_COMMAND_SERVICE.EXTRA_BACKGROUND is false):
- EXTRA_PLUGIN_RESULT_BUNDLE_STDOUT will contain session transcript.
- EXTRA_PLUGIN_RESULT_BUNDLE_STDERR will be null since its not used.
- EXTRA_PLUGIN_RESULT_BUNDLE_EXIT_CODE will contain exit code of session.
For background commands (RUN_COMMAND_SERVICE.EXTRA_BACKGROUND is true):
- EXTRA_PLUGIN_RESULT_BUNDLE_STDOUT will contain stdout of commands.
- EXTRA_PLUGIN_RESULT_BUNDLE_STDERR will contain stderr of commands.
- EXTRA_PLUGIN_RESULT_BUNDLE_EXIT_CODE will contain exit code of command.
The internal errors raised by termux outside the shell will be sent in the the EXTRA_PLUGIN_RESULT_BUNDLE_ERR and EXTRA_PLUGIN_RESULT_BUNDLE_ERRMSG extras. These will contain errors like if starting a termux command failed or if the user manually exited the termux sessions or android killed the termux service before the commands had finished executing. The err value will be Activity.RESULT_OK(-1) if no internal errors are raised.
The stdout and stderr will be truncated from the start to max 100KB combined and errmsg will also be truncated from end to max 25KB. This is necessary to prevent TransactionTooLargeException exceptions from being raised if stdout or stderr are too large in length. The original length of stdout and stderr will be provided in EXTRA_PLUGIN_RESULT_BUNDLE_STDOUT_ORIGINAL_LENGTH and EXTRA_PLUGIN_RESULT_BUNDLE_STDERR_ORIGINAL_LENGTH extras respectively, so that the caller can check if either of them were truncated.
### Termux:Tasker
Support for Termux:Tasker for getting back result of foreground commands will require an update to it since it currently immediately returns control to plugin host app like Tasker without waiting if a foreground command is to be executed.
If its set to `true` in termux.properties file, then soft keyboard will automatically be hidden on Termux App start to solve issues for when users use hardware keyboard and soft keyboard is automatically opened and wastes terminal screen space.
The `TermuxPropertyConstants` classes has been updated to `v0.5.0`. Check its Changelog sections for info on changes.
Fixes#1978
For android version >= 10(Q), a flash will be shown to users requesting them to grant the permission if they attempt to start a foreground terminal session command from background, like with the RUN_COMMAND intent. The flash will only be shown if "Plugin Error Notifications" toggle is enabled in settings.
Previously, the null or empty executable would be expanded to the literal root "/" string path by FileUtils.getCanonicalPath and then FileUtils.validateRegularFileExistenceAndPermissions() validation would fail since path will not be a regular file. So a user will be shown that "/" is not a regular file. Now we show that executable was not even passed.
TermuxTask will maintain info for background Termux tasks. Each task started by TermuxService will now be linked to a ExecutionCommand that started it.
- StreamGobbler class has also been imported from https://github.com/Chainfire/libsuperuser and partially modified to read stdout and stderr of background commands. This should likely be much safer and efficient.
- Logging of every line has been disabled unless log level is set to verbose. This should have a performance increase and also prevent potentially private user data to be sent to logcat.
- This also solves the bug where Termux:Tasker would hang indefinitely if Runtime.getRuntime().exec raised an exception, like for invalid or missing interpreter errors and Termux:Tasker wasn't notified of it. Now the errmsg will be used to send any exceptions back to Termux:Tasker and other 3rd party calls.
- This also solves the bug where stdout or stderr were too large in size and TransactionTooLargeException exception was raised and result TERMUX_SERVICE.EXTRA_PENDING_INTENT pending intent failed to be sent to the caller. This would have also hung up Termux:Tasker. Now the stdout and stderr sent back in TERMUX_SERVICE.EXTRA_PLUGIN_RESULT_BUNDLE bundle will be truncated from the start to max 100KB combined. The original size of stdout and stderr will be provided in TERMUX_SERVICE.EXTRA_PLUGIN_RESULT_BUNDLE_STDOUT_ORIGINAL_LENGTH and TERMUX_SERVICE.EXTRA_PLUGIN_RESULT_BUNDLE_STDERR_ORIGINAL_LENGTH extras respectively so that the caller can check if either of them were truncated. The errmsg will also be truncated from end to max 25KB to preserve start of stacktraces.
- The PluginUtils.processPluginExecutionCommandResult() has been updated to fully handle the result of plugin execution intents.
- Helper functions are now provided to check for common states. The currentState and previousState must only be modified via setState()
- Some errCode values are also provided to prevent hardcoded value usage.
- The stdout, stderr and arguments will now be truncated for logcat to honour its LOGGER_ENTRY_MAX_LEN limits
TermuxSession will maintain info for foreground Termux sessions. Each terminal session started by TermuxService will now be linked to a ExectionCommand that started it.
This also fixes bugs where newly created session in some cases were not being automatically selected and scrolled to, like when adding a named or failsafe session or those which were created for executable intents.
