RE: Issue with Cygwin perl *** fatal error - fork: can't reserve memory for stack

[RamÃn GarcÃa FernÃndez <ramong at cnmv dot es>]

We did put a ticket for this issue. It is not really necessary to strace rebase.pl. When rebase was invoked with a long command, any attempt to fork, including a call to perl system() before anything else, causes this issue.

I suggest not to translate junctions to targets, even if the functionality is in cygwin1.dll. It is surprising.

I'll try if it's within perl. Before I see no problem with perl's fork, but maybe it's elsewhere.

What is your openoffice ticket url for this problem?
With http://www.openoffice.org/servlets/ReadMsg?listName=allsvn&msgNo=9427

I see a possible problem in:
  my $command = "rebase " . $options_string; where $options_string can get too large and the error message should be improved.
I don't think perl has a test for argument length limits yet. I'll investigate.

If within the cygwin1.dll you have to be more specific were exactly.
A part of the strace of the failing rebase.pl call would help.

> On the other hand, I tried creating a junction point with linkd.exe so that I could use short names for the openoffice source tree. But this didn't work becase the configure script translated junction points, because cygpath translates them. Why? This is surprising. For example if c:\ooo is a junction to c:\Documents and settings\myuser\openoffice, why should cygpath -w /cygdrive/c/ooo return c:\Documents...\openoffice rather than c:\ooo? At least that translation should be optional.

This is a behaviour within the cygwin dll.
