If any of these deprecated features is a cause for concern for you, please
|
|
|
|
|
email the curl-library mailing list as soon as possible and explain to us why
|
|
|
|
|
this is a problem for you and how your use case can't be satisfied properly
|
|
|
|
|
using a work around.

## `CURLOPT_DNS_USE_GLOBAL_CACHE`
|
2018-09-04 18:05:46 -04:00
|
|
|
|
|
|
|
|
This option makes libcurl use a global non-thread-safe cache for DNS if
|
|
|
|
|
enabled. The option has been marked as "obsolete" in the header file and in
|
|
|
|
|
documentation for several years already.
|
|
|
|
|
|
|
|
|
|
There's proper and safe method alternative provided since many years: the
|
|
|
|
|
share API.
|
|
|
|
|
|
|
|
|
|
### State
|
|
|
|
|
|
|
|
|
|
In curl 7.62.0 setting this option to TRUE will not have any effect. The
|
|
|
|
|
global cache will not be enabled. The code still remains so it is easy to
|
|
|
|
|
revert if need be.
|
|
|
|
|
|
|
|
|
|
### Removal
|
|
|
|
|
|
|
|
|
|
Remove all global-cache related code from curl around April 2019 (might be
|
|
|
|
|
7.66.0).

|
## HTTP/0.9
|
|
|
|
|
|
|
|
|
|
Supporting this is non-obvious and might even come as a surprise to some
|
|
|
|
|
users. Potentially even being a security risk in some cases.
|
|
|
|
|
|
|
|
|
|
### State
|
|
|
|
|
|
|
|
|
|
curl 7.64.0 introduces options to disable/enable support for this protocol
|
|
|
|
|
version. The default remains supported for now.
|
|
|
|
|
|
|
|
|
|
### Removal
|
|
|
|
|
|
|
|
|
|
The support for HTTP/0.9 will be switched to disabled by default in 6 months,
|
|
|
|
|
in the September 2019 release (possibly called curl 7.68.0).
