new 3e38c39b60 Fix #11899: Default addLocationInformation to false in
Settings and Toolchains XML writers (#11984)
3e38c39b60 is described below
commit 3e38c39b60199cbf2eef32a8b401752cd1551f34
Author: Abhishek Chauhan <[email protected]>
AuthorDate: Wed May 20 10:23:13 2026 +0530
Fix #11899: Default addLocationInformation to false in Settings and
Toolchains XML writers (#11984)
* Fix gh-11899: Default addLocationInformation to false in Settings and
Toolchains XML writers
DefaultSettingsXmlFactory.write() and DefaultToolchainsXmlFactory.write()
always emitted InputLocation comments (e.g. <!-- /path/to/settings.xml:163
-->)
because they created bare StaxWriter instances whose addLocationInformation
field defaults to true, and never called setAddLocationInformation(false).
Align both factories with DefaultModelXmlFactory.write(), which correctly
defaults location tracking to false and only enables it when an explicit
inputLocationFormatter is provided via XmlWriterRequest.
Fixes #11899
* Add tests for DefaultSettingsXmlFactory location tracking behavior
Co-Authored-By: Claude Opus 4.6 <[email protected]>
* Add DefaultToolchainsXmlFactory test and strengthen assertions
