Claus Ibsen created CAMEL-24835:
-----------------------------------
Summary: camel-file: a consumer on the current directory (file:.
or file:./) never delivers a file
Key: CAMEL-24835
URL: https://issues.apache.org/jira/browse/CAMEL-24835
Project: Camel
Issue Type: Bug
Components: camel-file
Reporter: Claus Ibsen
A route that reads from the directory the application runs in delivers nothing,
without any warning:
{code:yaml}
- route:
from:
uri: "file:.?noop=true&include=order.json"
steps:
- log: "READ ${header.CamelFileName}"
{code}
The route starts ({{Started route1 (file://.)}}) and never logs. {{file:./}}
behaves the same. {{file:sub}} and an absolute path deliver the file at once. A
{{pollEnrich}} with {{file://.?fileName=order.json}} returns null for the same
reason.
Cause: {{FileConsumer.listFiles}} returns null when {{directory.isHidden()}} is
true and hidden directories are not included, and {{new File(".").isHidden()}}
is true on Unix, because {{java.io.File.isHidden}} only looks at whether the
name starts with a dot. The current directory is not hidden; its name is.
Suggested fix: resolve the directory before the hidden check (canonical or real
path), or exempt {{.}} and {{..}} from it. The same check in
{{isMatchedHiddenFile}} for sub-directories is fine, as a sub-directory named
with a dot is hidden.
Found by a local model in the round-2 benchmark on the camel-jbang-examples
ladder (Camel 4.23.0-SNAPSHOT, main d1d54fb835b2): two of six examples used
{{file:.}} to read a file next to the route and got no output and no message. A
person writing the same gets the same silence.
