Summary: Add $WARNING to make it easier to get the original behavior (print the `***` contact support stuff). Remove misc environment variables included in $WARNING to make the code simpler and less dependent. Besides, store traceback in $TRACE so that it will be easier to read it for multiple times. For example, try to upload it (first read) and if failed, print it locally (second read). Otherwise we need ugly hack like `A=$(cat)` in the script. Test Plan: Check the new examples manually and run test-errorredirect.t Reviewers: #sourcecontrol, ttung, rmcelroy Reviewed By: rmcelroy Differential Revision: https://phabricator.fb.com/D2770557 Tasks: 9259456 Signature: t1:2770557:1450384683:672e76752040d3d1b440522dd54ac43306c76bf9

"""redirect error message
|
|
|
|
Redirect error message, the stack trace, of an uncaught exception to
|
|
a custom shell script. This is useful for futher handling the error,
|
|
for example posting it to a support group and logging it somewhere.
|
|
|
|
The config option errorredirect.script is the shell script to execute.
|
|
If it's empty, the extension will do nothing and fallback to the old
|
|
behavior.
|
|
|
|
Two environment variables are set: TRACE is the stack trace, which
|
|
is the same as piped content. WARNING is the warning message, which
|
|
usually contains contact message and software versions, etc.
|
|
|
|
Examples::
|
|
|
|
[errorredirect]
|
|
script = tee hgerr.log && echo 'Error written to hgerr.log'
|
|
|
|
[errorredirect]
|
|
script = echo "$WARNING$TRACE" >&2
|
|
|
|
[errorredirect]
|
|
script = (echo "$WARNING"; cat) | cat >&2
