[bug-gawk] Odd behaviour

[McKinnon, Gordon]

Hello,

 

I have an interesting problem.  I’m working on a DRP server that is supposed to run like an existing server.  The O/Ses are not identical:

 

New server:

 

Red Hat Enterprise Linux Server release 6.5 (Santiago), gawk-3.1.7-10.el6.x86_64

 

Old server:

Red Hat Enterprise Linux Server release 5.8 (Tikanga), gawk-3.1.5-15.el5

 

On the old server there are some scripts that read and write with French accents:

 

[pid 27295] read(3, "H (Taxe de vente harmonis\351e): R1"..., 4096) = 4096

[pid 27295] read(3, " de vente harmonis\351e): R10045865"..., 4096) = 4096

[pid 27295] write(20, "nte harmonis\351e): R100458652&&|en"..., 4096) = 4096

[pid 27295] write(20, "H (Taxe de vente harmonis\351e): R1"..., 4096) = 4096

[pid 27295] write(20, "e de vente harmonis\351e): R1004586"..., 4096) = 4096

[pid 27295] write(20, "VH (Taxe de vente harmonis\351e): R"..., 4096) = 4096

[pid 27295] read(3, "ces)/TVH (Taxe de vente harmonis"..., 4096) = 4096

[pid 27295] read(3, "te harmonis\351e): R100458652&&|eng"..., 4096) = 4096

[pid 27295] read(3, "e vente harmonis\351e): R100458652&"..., 4096) = 4096

[pid 27295] write(20, "ces)/TVH (Taxe de vente harmonis"..., 4096) = 4096

[pid 27295] write(23, ")/TVH (Taxe de vente harmonis\351e)"..., 4096) = 4096

[pid 27295] read(3, "es)/TVH (Taxe de vente harmonis\351"..., 4096) = 4096

[pid 27295] write(23, "ces)/TVH (Taxe de vente harmonis"..., 4096) = 4096

[pid 27295] read(3, "(Taxe de vente harmonis\351e): 8893"..., 4096) = 4096

[pid 27295] write(23, " harmonis\351e): 889301842&&|eng&&B"..., 4096) = 4096

[pid 27295] read(3, "H (Taxe de vente harmonis\351e): 88"..., 4096) = 4096

 

On the old servers the reads and writes match, it reads \351 and writes \351.

 

On the newer server I get:

 

[pid 15918] read(3, "s)/TVH (Taxe de vente harmonis\351e"..., 4096) = 4096

[pid 15918] read(3, "harmonis\351e): R100458652&&|eng&&B"..., 4096) = 4096

[pid 15918] write(19, "H (Taxe de vente harmonis\n120|45"..., 4096) = 4096

[pid 15918] read(3, "nte harmonis\351e): R100458652&&|en"..., 4096) = 4096

[pid 15918] read(3, "H (Taxe de vente harmonis\351e): R1"..., 4096) = 4096

[pid 15918] write(19, "ces)/TVH (Taxe de vente harmonis"..., 4096) = 4096

[pid 15918] read(3, " de vente harmonis\351e): R10045865"..., 4096) = 4096

[pid 15918] write(20, "H (Taxe de vente harmonis\n121|51"..., 4096) = 4096

[pid 15918] write(20, ")/TVH (Taxe de vente harmonis\n12"..., 4096) = 4096

[pid 15918] read(3, "ces)/TVH (Taxe de vente harmonis"..., 4096) = 4096

[pid 15918] read(3, "te harmonis\351e): R100458652&&|eng"..., 4096) = 4096

[pid 15918] write(20, "harmonis\n121|5147214004   319-CB"..., 4096) = 4096

[pid 15918] write(20, "vices)/TVH (Taxe de vente harmon"..., 4096) = 4096

[pid 15918] read(3, "e vente harmonis\351e): R100458652&"..., 4096) = 4096

[pid 15918] write(20, "vente harmonis\n121|8193263335   "..., 4096) = 4096

[pid 15918] write(21, "H (Taxe de vente harmonis\n122|51"..., 1246) = 1246

[pid 15918] write(22, "H (Taxe de vente harmonis\n123|41"..., 942) = 942

[pid 15918] read(3, "es)/TVH (Taxe de vente harmonis\351"..., 4096) = 4096

[pid 15918] read(3, "(Taxe de vente harmonis\351e): 8893"..., 4096) = 4096

[pid 15918] write(23, "/TVH (Taxe de vente harmonis\n125"..., 4096) = 4096

 

So it reads \351 and writes a carriage return.

 

I copied the awk binary from the old server to the new server and then the accents were read and written correctly.

 

I’m a little surprised by this behaviour.  I didn’t see anything obvious in the release notes for those versions but then they are a little old, even if the non-functional one is RHEL standard.  I’ll get the tier 1 sysadmins to check with RedHat as well but I’d like to know if this is a known bug.

 

Thank you,
