🌐 Web query:
gopkg.in/ini.v1 PrettyFormat PrettyEqual API instance vs global
💡 Result:
Short answer: PrettyFormat and PrettyEqual are package-level global variables (not per-File instance). Changing them affects all writes done by the gopkg.in/ini.v1 package. See the package variables listing (PrettyFormat, PrettyEqual) in the API/source. [1][2]
Notes / quick options:
- Set ini.PrettyFormat / ini.PrettyEqual before calling SaveTo/WriteTo to control output globally. [1]
- If you need per-File behavior you must manage it yourself (e.g. set the globals just before writing a specific File and restore them after, or copy/fork the library to add per-File options). [2]
Sources:
- Package variables (PrettyFormat, PrettyEqual) in gopkg.in/ini.v1 API/source. [1]
- ini.go source showing those variables and comments. [2]

Race condition: concurrent modification of global ini package variables.
The code mutates package-level global variables (ini.PrettyFormat and ini.PrettyEqual) in a concurrent context. UpdateConfigurationFiles() in server/config_parser.go (line 37) creates a worker pool with runtime.NumCPU() workers and submits Parse() tasks concurrently (line 45). When parsing INI files, each goroutine executes parseIniFile() which modifies these globals at lines 322-323, then calls WriteTo() (line 390) which reads them. Multiple goroutines reading and writing the same unprotected global variables creates a data race.
Use a sync.Mutex to guard these assignments, or configure formatting before calling Parse() once rather than repeatedly within the goroutines.
🤖 Prompt for AI Agents
In parser/parser.go around lines 321 to 323, the code mutates package-level
globals ini.PrettyFormat and ini.PrettyEqual from concurrent goroutines causing
a data race; protect these assignments with a sync.Mutex (declare a
package-level or parser-scoped mutex and lock/unlock around any read/write of
those ini package globals, including WriteTo usage), or better move the
formatting configuration out of parseIniFile and set
ini.PrettyFormat/ini.PrettyEqual once before launching the worker pool so
goroutines no longer modify shared state.
