Hi Przemek,
* harbour/contrib/hbcurl/hbcurl.c
+ use hash table to keep strings passed to CURL library accessible
even if HVM destroys them. It should allow to safely use HBCURL
wrapper also with CURL library older then 7.17.0 though it can
be a little bit expensive in some cases. The allocated strings
are freed when CURL pointer is destroyed (directly or by
CURL_EASY_CLEANUP()) or reset by CURL_EASY_RESET().
This feature is enabled only when compiled for CURL libraries
older then 7.17.0 or when user set explicitly compile time macro
HB_CURL_HASH_STRINGS
Viktor, you are more familiar with this code so please check it.
Many thanks, it looks good to me, except a few minor past an
new things:
1) Re-reading the docs now, it seems that there is at least one place
where your new method to cache strings is needed regardless of libcurl
version: curl_formadd() with CURLFORM_COPYNAME. The docs says we should
copy the string. So this might have been a pending bug in hbcurl.
2) curl_slist_append() does copy the string, so we don't need to deal
with it, at least as per the latest docs on the website.
Brgds,
Viktor
