2019-05-11doh: disable DOH for the cases it doesn't workDaniel Stenberg
Due to limitations in Curl_resolver_wait_resolv(), it doesn't work for DOH resolves. This fix disables DOH for those. Limitation added to KNOWN_BUGS. Fixes #3850 Closes #3857
2019-03-01urldata: simplify bytecountersDaniel Stenberg
- no need to have them protocol specific - no need to set pointers to them with the Curl_setup_transfer() call - make Curl_setup_transfer() operate on a transfer pointer, not connection - switch some counters from long to the more proper curl_off_t type Closes #3627
2019-02-27urldata: convert bools to bitfields and move to endDaniel Stenberg
This allows the compiler to pack and align the structs better in memory. For a rather feature-complete build on x86_64 Linux, gcc 8.1.2 makes the Curl_easy struct 4.9% smaller. From 6312 bytes to 6000. Removed an unused struct field. No functionality changes. Closes #3610
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
2018-12-17pingpong: ignore regular timeout in disconnect phaseDaniel Stenberg
The timeout set with CURLOPT_TIMEOUT is no longer used when disconnecting from one of the pingpong protocols (FTP, IMAP, SMTP, POP3). Reported-by: jasal82 on github Fixes #3264 Closes #3374
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
2018-10-03memory: ensure to check allocation resultsDaniel Gustafsson
The result of a memory allocation should always be checked, as we may run under memory pressure where even a small allocation can fail. This adds checking and error handling to a few cases where the allocation wasn't checked for success. In the ftp case, the freeing of the path variable is moved ahead of the allocation since there is little point in keeping it around across the strdup, and the separation makes for more readable code. In nwlib, the lock is aslo freed in the error path. Also bumps the copyright years on affected files.

... to make it a truly unified URL parser. Closes #3017
2018-09-13ftp: include command in Curl_ftpsend sendbufferDaniel Gustafsson
Commit 8238ba9c5f10414a88f502bf3f5d5a42d632984c inadvertently removed the actual command to be sent from the send buffer in a refactoring. Add back copying the command into the buffer. Also add more guards against malformed input while at it. Closes #2985 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2018-06-12Curl_debug: remove dead printhost codeDaniel Stenberg
The struct field is never set (since 5e0d9aea3) so remove the use of it and remove the connectdata pointer from the prototype. Reported-by: Tejas Bug: https://curl.haxx.se/mail/lib-2018-06/0054.html Closes #2647

2018-04-06FTP: allow PASV on IPv6 connections when a proxy is being usedLaurie Clark-Michalek
In the situation of a client connecting to an FTP server using an IPv6 tunnel proxy, the connection info will indicate that the connection is IPv6. However, because the server behing the proxy is IPv4, it is permissable to attempt PSV mode. In the case of the FTP server being IPv4 only, EPSV will always fail, and with the current logic curl will be unable to connect to the server, as the IPv6 fwdproxy causes curl to think that EPSV is impossible. Closes #2432

Fixes #2380
2018-03-12FTP: reject path components with control codesDaniel Stenberg
Refuse to operate when given path components featuring byte values lower than 32. Previously, inserting a %00 sequence early in the directory part when using the 'singlecwd' ftp method could make curl write a zero byte outside of the allocated buffer. Test case 340 verifies.

2017-10-28Curl_timeleft: change return type to timediff_tDaniel Stenberg
returning 'time_t' is problematic when that type is unsigned and we return values less than zero to signal "already expired", used in several places in the code. Closes #2021

2017-10-25time: rename Curl_tvnow to Curl_nowDaniel Stenberg

2017-06-15http-proxy: only attempt FTP over HTTP proxyDaniel Stenberg
