Simone Chiaretta commented on LUCENENET-357:
--------------------------------------------
I saw the LOCK_DIR has already been removed in the trunk. but the problem with
System.Environment.GetEnvironmentVariable still exists.
Not really sure how a possible approach could be
/// <summary>The value of
<tt>System.getProperty("os.name")</tt>. *</summary>
public static readonly System.String OS_NAME =
System.Environment.GetEnvironmentVariable("OS") ?? "Linux";
/// <summary>True iff running on Linux. </summary>
public static readonly bool LINUX = OS_NAME.StartsWith("Linux");
/// <summary>True iff running on Windows. </summary>
public static readonly bool WINDOWS =
OS_NAME.StartsWith("Windows");
/// <summary>True iff running on SunOS. </summary>
public static readonly bool SUN_OS =
OS_NAME.StartsWith("SunOS");
public static readonly System.String OS_ARCH =
System.Environment.GetEnvironmentVariable("PROCESSOR_ARCHITECTURE");
public static readonly System.String OS_VERSION =
System.Environment.OSVersion.ToString();
public static readonly System.String JAVA_VENDOR =
SupportClass.AppSettings.Get("java.vendor", "");
OS_ARCH and OS_VERSION are used only for logging the config of the machine in
the error message... I think these can be removed
OS_NAME is only used indirectly with the WINDOWS flag in these two points in
the code:
public static FSDirectory Open(System.IO.DirectoryInfo path,
LockFactory lockFactory)
{
/* For testing:
MMapDirectory dir=new MMapDirectory(path, lockFactory);
dir.setUseUnmap(true);
return dir;
*/
if (Constants.WINDOWS)
{
return new SimpleFSDirectory(path, lockFactory);
}
else
{
//NIOFSDirectory is not implemented in Lucene.Net
//return new NIOFSDirectory(path, lockFactory);
return new SimpleFSDirectory(path, lockFactory);
}
}
Which in both branches does the exact same thing
and in
static IndexWriter()
{
DEFAULT_MERGE_FACTOR =
LogMergePolicy.DEFAULT_MERGE_FACTOR;
DEFAULT_MAX_MERGE_DOCS =
LogDocMergePolicy.DEFAULT_MAX_MERGE_DOCS;
MAX_TERM_LENGTH = DocumentsWriter.MAX_TERM_LENGTH;
{
if (Constants.WINDOWS)
DEFAULT_MAX_SYNC_PAUSE_SECONDS = 10.0;
else
DEFAULT_MAX_SYNC_PAUSE_SECONDS = 0.0;
}
}
I've no idea of why windows and other OSes might have different defaults...
So, just putting
public static readonly System.String OS_NAME = "Windows";
public static readonly System.String OS_ARCH = "x86";
public static readonly System.String OS_VERSION = String.Empty;
in the Constants.cs file will fix the problem with the only side effect of
always forcing DEFAULT_MAX_SYNC_PAUSE_SECONDS = 10.0;
