#3974 closed enhancement (fixed)

Case insensitive ERS parsing

Reported by: rprinceley Owned by: warmerdam
Priority: normal Milestone: 1.8.1
Component: GDAL_Raster Version: svn-trunk
Severity: normal Keywords: ERS
Cc: gaopeng

Description

We have a few user submitted ERS files that are all lowercase (except quoted strings). GDAL fails parsing such files, but these are supported by ERDAS applications (and older versions of ArcGIS).

I don't immediately see obvious case sensitivity issues in the gdal/frmts/ers. Could you attach a header that demonstrates the problem?

Frank,

The problem is in ERSHdrNode::ParseChildren?. CPLString (based on std::string) is case sensitive, CPLString::find() ends up calling memcmp() to compare strings.

I have corrected the problem in trunk (r21813,r21814), 1.8 (r21815) and 1.8-esri (r21817).

Testing added in trunk (r21818).
