* OpenSSL SSL_read: error:0A000126:SSL routines::unexpected eof while reading, errno 0
* Closing connection 0
reading the discussion on https://github.com/openssl/openssl/discussions/22690 suggest to set the option SSL_OP_IGNORE_UNEXPECTED_EOF
which makes check_curl behave like check_http at this point.
Since this is a rather new flag, fencing it in ifdefs.
And since there can only be one ssl ctx function, we need to move both tasks into one function.

Check disk static fixes
|
|
|
|
Variables only used in that specific translation unit should be static
to actually communicate that fact.
Also allows the compiler to detect unused (global) variables.

|

check_mysql:
* remove unused variables
* convert two practical booleans to real `bool`

Add more documentation to the help page of check_snmp regarding authe…
|
|
|
|
Previously the --state-regex option accepted only "critical" and
"warning" as values.
This commit changes the strcmp there to strcasecmp to be more tolerant
regarding the input.
|
|
The help output of `check-curl` contained a typo,
the real option is `state-regex` and not `regex-state` as
the help suggests.
Also added the two possible options to avoid confusion.
|
|
From the mere help output for -C / --certificate, I was confused about
what its two integer parameters do. Unfortunately, I also missed out on
the explaining examples later. Since I like to have basic documentation
for each flag, I tried to make the arguments as short as possible.
The other fix was one hyphen too many for the --cookie-jar option.

This change aims to raise the worst status between the SSL check and the HTTP check.

Having a webserver respond with a relative redirect as for ex. in `Location: /path/to.html`
check_curl would use the wrong standard http/https port instead
of crafting the absolute url using the given scheme/hostname and port.
Adding a new test case for this for check_http and check_curl. check_http did
it correct already, so no fix necessary there.

this makes tests more reliable if we test our own sites instead some 3rd party site.

regex check
from the default CRITICAL to something else (#1213)
|
|
|
|
adaugherity noticed in issue #1965, that HAVE_PROC_LOADAVG is never
defined since the symbol was removed from configure quite some time ago.
This commit removes the dead code which would be used when the symbol
would have been defined.
|
|
test case (#1935)
* check_disk: Fail on missing arguments for --warning and --critical
* Add new test function for percentage expressions and use it in check_disk
* Add error abort in tests if they fail to parse output
* Fix typo in test which probably broke the test since forever :-(
