On overworked CVS servers, the "synch with stream" operation will fail with a dialog stating "CVS Communication Error". My suggestions are: 1. Add a configurable timeout value 2. Make a better error message - this took several hours of concentrated effort to find My workaround was to build a dedicated CVS server. I found this stack trace to let me know what the problem was: Log: Mon Nov 19 15:51:20 CST 2001 4 org.eclipse.vcm.core 4 CVS communication error java.io.InterruptedIOException: Read timed out at java.net.SocketInputStream.socketRead(Native Method) at java.net.SocketInputStream.read(SocketInputStream.java(Compiled Code)) at java.io.BufferedInputStream.fill(BufferedInputStream.java(Compiled Code)) at java.io.BufferedInputStream.read(BufferedInputStream.java(Compiled Code)) at org.eclipse.vcm.internal.core.ccvs.client.Connection.readLineOrUntil (Connection.java(Compiled Code)) at org.eclipse.vcm.internal.core.ccvs.client.Connection.readToken(Connection.ja va:310) at org.eclipse.vcm.internal.core.ccvs.client.Client.processResponses(Client.jav a:457) at org.eclipse.vcm.internal.core.ccvs.client.Client.processResponses(Client.jav a:440) at org.eclipse.vcm.internal.core.ccvs.client.Client.execute(Client.java:293) at org.eclipse.vcm.internal.core.ccvs.CVSAdapter.fetchRemoteTree(CVSAdapter.jav a:607) at org.eclipse.vcm.internal.core.Subscriber.refresh(Subscriber.java:517) at org.eclipse.vcm.internal.core.Subscriber$3.run(Subscriber.java:485) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:1197) at org.eclipse.vcm.internal.core.Subscriber.run(Subscriber.java:536) at org.eclipse.vcm.internal.core.SharingManager.run(SharingManager.java:676) at org.eclipse.vcm.internal.core.Subscriber.refresh(Subscriber.java:479) at org.eclipse.vcm.internal.ui.sync.Repository.doServerDelta(Repository.java:18 1) at org.eclipse.vcm.internal.ui.sync.Repository$1.execute(Repository.java:225) at org.eclipse.ui.actions.WorkspaceModifyOperation$1.run(WorkspaceModifyOperati on.java:64) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:1197) at org.eclipse.ui.actions.WorkspaceModifyOperation.run(WorkspaceModifyOperation .java:78) at org.eclipse.vcm.internal.ui.sync.Repository.localServerDelta(Repository.java :229) at org.eclipse.vcm.internal.ui.sync.SyncCompareInput.prepareInput(SyncCompareIn put.java:434) at org.eclipse.compare.CompareEditorInput.run(CompareEditorInput.java:596) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext .java:98)
Fixed in 2.0. CVS communication timeout is configurable via the preferences dialog. The timeout value is used for both extssh and pserver connection methods. In addition, if a timeout occurs the error message is more informative.
