[news.eclipse.dsdp.tm] Cygwin Support?

renaud.denis@xxxxxxx (Renaud Denis) — Fri, 03 Jul 2009 12:13:46 GMT

Hi everyone,

I hope I'm in the right newsgroup here.

Just wondering if there's any plan for support of cygwin shell as a local shell for windows platforms...

For those like me still using a lot a shell, notably to drive maven, that would be a great improvement to be able to work in a local bash/cygwin shell inside the IDE.

regards,
Renaud

Hi David, The problem of OutOfMemoryError has solved,thanks! But I have the other question: RSE FTP will use more time than other FTP such as cuteftp to upload a file. So RSE FTP's efficiency of transmission is lower than other ftp. How to enhance the transmission efficiency of RSE FTP?

Have you any way to avoid copying file to RemoteSystemsTempFiles and directly copy a file from source to target folder? or is there a switch when opening a file for editing, RSE downloads to the RemoteSystemsTempFiles and when uploading or downloading a file, RSE copy a file from source to target folder directly, not pass through RemoteSystemsTempFiles?

Best Regards,
hemeihua

That would explain it then.  The daemon needs to be run as root but the 
servers that gets started as run as the client user.

At the moment there is no ability to for the server to start executing as 
root and then switch to the client user.

In order to bind a socket to a privileged port, the process must be running as root. So I think it must be failing because the server process is running as the client user ID (auth.pl does an "su" to the client user ID to spawn the server). I assume that the server runs as the client user ID for a reason (exporting the client environment, client permissions, etc).

So my next question would be is there a way that the server could maybe start executing as root to bind the socket and make the connection, then switch to the client user ID to get the proper environment and do the remaining "real" work? Could that work or would there still be problems sending data over the port?

Hi Denise,

The RSE dstore server doesn't distinguish between privileged and 
non-privileged ports so I'm not sure what's causing the connection to fail 
in this case.

Hi hemeihua,

I don't know that much about the details of the FTP service implementation 
but I'll try to help here.  FTPService leverages FTPClient from apache 
commons.  There is a method to get the FTPClient, getFTPClient() from the 
service.  FTPClient extends SocketClient which has the following method:

/**
* Sets the connection timeout in milliseconds, which will be passed to the 
{@link Socket} object's
* connect() method.
* @param connectTimeout The connection timeout to use (in ms)
* @since 2.0
*/
public void setConnectTimeout(int connectTimeout) {
  this.connectTimeout = connectTimeout;
}
Is that what you're looking for?

Dave

Hi hemeihua,

In this particular scenario, I don't think setting the "maximum cached size" 
will make any difference.  The issue seems to be that when reading a very 
large file, too much heap memory is being consumed.

One workaround for this may be the following:

In the eclipse.ini file, memory args for the JVM can be set.  For example:

-Xms40m
-Xmx256m

You may be able to raise the max memory for Eclipse such that it will be 
able to handle larger heap memory consumption.

Let me know whether this helps.
Dave

Hello David, yes,"set maximum cached size" is referring to the value for the Remote Systems->File Cache preferences. I can upload a smaller file which size is about 100MB-600MB ,but can not upload a larger file(above 1GB) which can not been divided and an internal error occurred. How to deal with the internal error? To suppose that I uploaded a large file(1.02GB) successfully, RSE FTP will use more time than other ftp such as cuteftp to upload a file. So RSE FTP's efficiency of transmission is lower than other ftp. How to enhance the transmission efficiency of RSE FTP?

Have you any way to avoid copying file to RemoteSystemsTempFiles and directly copy a file from source to target folder? or is there a switch when opening a file for editing, RSE downloads to the RemoteSystemsTempFiles and when uploading or downloading a file, RSE copy a file from source to target folder directly, not pass through RemoteSystemsTempFiles?
