2019-02-26strerror: make the strerror function use local buffersDaniel Stenberg
Instead of using a fixed 256 byte buffer in the connectdata struct. In my build, this reduces the size of the connectdata struct by 11.8%, from 2160 to 1904 bytes with no functionality or performance loss. This also fixes a bug in schannel's Curl_verify_certificate where it called Curl_sspi_strerror when it should have called Curl_strerror for string from GetLastError. the only effect would have been no text or the wrong text being shown for the error. Co-authored-by: Jay Satiro Closes #3612
2018-11-23snprintf: renamed and we now only use msnprintf()Daniel Stenberg
The function does not return the same value as snprintf() normally does, so readers may be mislead into thinking the code works differently than it actually does. A different function name makes this easier to detect. Reported-by: Tomas Hoger Assisted-by: Daniel Gustafsson Fixes #3296 Closes #3297

2017-07-11strerror: Preserve Windows error code in some functionsJay Satiro
This is a follow-up to af02162 which removed (SET_)ERRNO macros. That commit was an earlier draft that I committed by mistake, which was then remedied by a5834e5 and e909de6, and now this commit. With this commit there is now no difference between the current code and the changes that were approved in the final draft.

2017-07-10curl_setup_once: Remove ERRNO/SET_ERRNO macrosJay Satiro
Prior to this change (SET_)ERRNO mapped to GetLastError/SetLastError for Win32 and regular errno otherwise. I reviewed the code and found no justifiable reason for conflating errno on WIN32 with GetLastError/SetLastError. All Win32 CRTs support errno, and any Win32 multithreaded CRT supports thread-local errno. Fixes https://github.com/curl/curl/issues/895 Closes https://github.com/curl/curl/pull/1589

2016-09-07errors: new alias CURLE_WEIRD_SERVER_REPLY (8)Jay Satiro
Since we're using CURLE_FTP_WEIRD_SERVER_REPLY in imap, pop3 and smtp as more of a generic "failed to parse" introduce an alias without FTP in the name. Closes https://github.com/curl/curl/pull/975
2016-04-29lib: include curl_printf.h as one of the last headersDaniel Stenberg
curl_printf.h defines printf to curl_mprintf, etc. This can cause problems with external headers which may use __attribute__((format(printf, ...))) markers etc. To avoid that they cause problems with system includes, we include curl_printf.h after any system headers. That makes the three last headers to always be, and we keep them in this order: curl_printf.h curl_memory.h memdebug.h None of them include system headers, they all do funny #defines. Reported-by: David Benjamin Fixes #743
2016-04-11http2: Add handling stream level errorTatsuhiro Tsujikawa
Previously, when a stream was closed with other than NGHTTP2_NO_ERROR by RST_STREAM, underlying TCP connection was dropped. This is undesirable since there may be other streams multiplexed and they are very much fine. This change introduce new error code CURLE_HTTP2_STREAM, which indicates stream error that only affects the relevant stream, and connection should be kept open. The existing CURLE_HTTP2 means connection error in general. Ref: https://github.com/curl/curl/issues/659 Ref: https://github.com/curl/curl/pull/663

2015-01-16url: add CURLOPT_SSL_VERIFYSTATUS optionAlessandro Ghedini
This option can be used to enable/disable certificate status verification using the "Certificate Status Request" TLS extension defined in RFC6066 section 8. This also adds the CURLE_SSL_INVALIDCERTSTATUS error, to be used when the certificate status verification fails, and the Curl_ssl_cert_status_request() function, used to check whether the SSL backend supports the status_request extension.
2014-10-24code cleanup: we prefer 'CURLcode result'Daniel Stenberg
... for the local variable name in functions holding the return code. Using the same name universally makes code easier to read and follow. Also, unify code for checking for CURLcode errors with: if(result) or if(!result) instead of if(result == CURLE_OK), if(CURLE_OK == result) or if(result != CURLE_OK)

2013-03-13Multiple pipelines and limiting the number of connections.Linus Nielsen Feltzing
Introducing a number of options to the multi interface that allows for multiple pipelines to the same host, in order to optimize the balance between the penalty for opening new connections and the potential pipelining latency. Two new options for limiting the number of connections: CURLMOPT_MAX_HOST_CONNECTIONS - Limits the number of running connections to the same host. When adding a handle that exceeds this limit, that handle will be put in a pending state until another handle is finished, so we can reuse the connection. CURLMOPT_MAX_TOTAL_CONNECTIONS - Limits the number of connections in total. When adding a handle that exceeds this limit, that handle will be put in a pending state until another handle is finished. The free connection will then be reused, if possible, or closed if the pending handle can't reuse it. Several new options for pipelining: CURLMOPT_MAX_PIPELINE_LENGTH - Limits the pipeling length. If a pipeline is "full" when a connection is to be reused, a new connection will be opened if the CURLMOPT_MAX_xxx_CONNECTIONS limits allow it. If not, the handle will be put in a pending state until a connection is ready (either free or a pipe got shorter). CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE - A pipelined connection will not be reused if it is currently processing a transfer with a content length that is larger than this. CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE - A pipelined connection will not be reused if it is currently processing a chunk larger than this. CURLMOPT_PIPELINING_SITE_BL - A blacklist of hosts that don't allow pipelining. CURLMOPT_PIPELINING_SERVER_BL - A blacklist of server types that don't allow pipelining. See the curl_multi_setopt() man page for details.
2013-01-09build: fix circular header inclusion with other packagesYang Tse
This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

2012-11-17mem-include-scan: verify memory #includesDaniel Stenberg
If we use memory functions (malloc, free, strdup etc) in C sources in libcurl and we fail to include curl_memory.h or memdebug.h we either fail to properly support user-provided memory callbacks or the memory leak system of the test suite fails. After Ajit's report of a failure in the first category in http_proxy.c, I spotted a few in the second category as well. These problems are now tested for by test 1132 which runs a perl program that scans for and attempts to check that we use the correct include files if a memory related function is used in the source code.

Neither of these errors are considered fatal and control connection remains OK because it could just be a firewall blocking server to connect to the client. 2- One new setopt option was introduced. CURLOPT_ACCEPTTIMEOUT_MS It sets the maximum amount of time FTP client is going to wait for a server to connect. Internal default accept timeout is 60 seconds.

2011-04-05return code cleanup: build, init and run-time errorsDaniel Stenberg
Stop the abuse of CURLE_FAILED_INIT as return code for things not being init related by introducing two new return codes: CURLE_NOT_BUILT_IN and CURLE_UNKNOWN_OPTION CURLE_NOT_BUILT_IN replaces return code 4 that has been obsoleted for several years. It is used for returning error when something is attempted to be used but the feature/option was not enabled or explictitly disabled at build-time. Getting this error mostly means that libcurl needs to be rebuilt. CURLE_FAILED_INIT is now saved and used strictly for init failures. Getting this problem means something went seriously wrong, like a resource shortage or similar. CURLE_UNKNOWN_OPTION is the option formerly known as CURLE_UNKNOWN_TELNET_OPTION (and the old name is still present, separately defined to be removed in a very distant future). This error code is meant to be used to return when an option is given to libcurl that isn't known. This problem would mostly indicate a problem in the program that uses libcurl.
2011-02-09CURLE_TLSAUTH_FAILED: removedQuinn Slack
On second thought, I think CURLE_TLSAUTH_FAILED should be eliminated. It was only being raised when an internal error occurred while allocating or setting the GnuTLS SRP client credentials struct. For TLS authentication failures, the general CURLE_SSL_CONNECT_ERROR seems appropriate; its error string already includes "passwords" as a possible cause. Having a separate TLS auth error code might also cause people to think that a TLS auth failure means the wrong username or password was entered, when it could also be a sign of a man-in-the-middle attack.
