2016-06-29conn: don't free easy handle data in handler->disconnectDaniel Stenberg
Reported-by: Gou Lingfeng Bug: https://curl.haxx.se/mail/lib-2016-06/0139.html
2016-06-28SFTP: set a generic error when no SFTP one exists...Daniel Stenberg
... as otherwise we could get a 0 which would count as no error and we'd wrongly continue and could end up segfaulting. Bug: https://curl.haxx.se/mail/lib-2016-06/0052.html Reported-by: 暖和的和暖
2016-06-22typedefs: use the full structs in internal code...Daniel Stenberg
... and save the typedef'ed names for headers and external APIs.
2016-06-22internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg
2016-05-30ssh: fix version number check typoDaniel Stenberg
2016-05-29ssh: fix build for libssh2 before 1.2.6Daniel Stenberg
The statvfs functionality was added to libssh2 in that version, so we switch off that functionality when built with older libraries. Fixes #831
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
2016-04-03code: style updatesDaniel Stenberg
2016-03-30multi: turn Curl_done into file local multi_doneDaniel Stenberg
... as it now is used by multi.c only.
2016-03-27SSH: new CURLOPT_QUOTE command "statvfs"marquis-de-muesli
usage: "statvfs path" returns remote file system statistics
2016-03-27SSH: support CURLINFO_FILETIMEmarquis-de-muesli
2016-02-14SCP: use libssh2_scp_recv2 to support > 2GB files on windowsDavid Byron
libssh2_scp_recv2 is introduced in libssh2 1.7.0 - to be released "any day now. Closes #451
2016-02-03URLs: change all http:// URLs to https://Daniel Stenberg
2016-01-15ssh: make CURLOPT_SSH_PUBLIC_KEYFILE treat "" as NULLKamil Dudka
The CURLOPT_SSH_PUBLIC_KEYFILE option has been documented to handle empty strings specially since curl-7_25_0-31-g05a443a but the behavior was unintentionally removed in curl-7_38_0-47-gfa7d04f. This commit restores the original behavior and clarifies it in the documentation that NULL and "" have both the same meaning when passed to CURLOPT_SSH_PUBLIC_KEYFILE. Bug: http://curl.haxx.se/mail/lib-2016-01/0072.html
2015-11-24Revert "cleanup: general removal of TODO (and similar) comments"Daniel Stenberg
This reverts commit 64e959ffe37c436503f9fed1ce2d6ee6ae50bd9a. Feedback-by: Dan Fandrich URL: http://curl.haxx.se/mail/lib-2015-11/0062.html
2015-11-13cleanup: general removal of TODO (and similar) commentsDaniel Stenberg
They tend to never get updated anyway so they're frequently inaccurate and we never go back to revisit them anyway. We document issues to work on properly in KNOWN_BUGS and TODO instead.
2015-10-15fread_func: move callback pointer from set to state structDaniel Stenberg
... and assign it from the set.fread_func_set pointer in the Curl_init_CONNECT function. This A) avoids that we have code that assigns fields in the 'set' struct (which we always knew was bad) and more importantly B) it makes it impossibly to accidentally leave the wrong value for when the handle is re-used etc. Introducing a state-init functionality in multi.c, so that we can set a specific function to get called when we enter a state. The Curl_init_CONNECT is thus called when switching to the CONNECT state. Bug: https://github.com/bagder/curl/issues/346 Closes #346
2015-08-10SFTP: fix range request off-by-one in size checkDaniel Stenberg
Reported-by: Tim Stack Closes #359
2015-08-02SSH: three state machine fixupsDaniel Stenberg
The SSH state machine didn't clear the 'rc' variable appropriately in a two places which prevented it from looping the way it should. And it lacked an 'else' statement that made it possible to erroneously get stuck in the SSH_AUTH_AGENT state. Reported-by: Tim Stack Closes #357
2015-05-20read_callback: move to SessionHandle from connectdataDaniel Stenberg
With many easy handles using the same connection for multiplexing, it is important we store and keep the transfer-oriented stuff in the SessionHandle so that callbacks and callback data work fine even when many easy handles share the same physical connection.
2015-03-17checksrc: use space after commaDaniel Stenberg
2015-03-16free: instead of Curl_safefree()Daniel Stenberg
Since we just started make use of free(NULL) in order to simplify code, this change takes it a step further and: - converts lots of Curl_safefree() calls to good old free() - makes Curl_safefree() not check the pointer before free() The (new) rule of thumb is: if you really want a function call that frees a pointer and then assigns it to NULL, then use Curl_safefree(). But we will prefer just using free() from now on.
2015-03-03mprintf.h: remove #ifdef CURLDEBUGDaniel Stenberg
... and as a consequence, introduce curl_printf.h with that re-define magic instead and make all libcurl code use that instead.
2014-12-16SFTP: work-around servers that return zero size on STATDaniel Stenberg
Bug: http://curl.haxx.se/mail/lib-2014-12/0103.html Pathed-by: Marc Renault
2014-11-09libssh2: detect features based on version, not configure checksDaniel Stenberg
... so that non-configure builds get the correct functions too based on the libssh2 version used.
2014-11-09SSH: use the port number as well for known_known checksNobuhiro Ban
... if the libssh2 version is new enough. Bug: http://curl.haxx.se/bug/view.cgi?id=1448
2014-11-05ssh: Fixed build on platforms where R_OK is not definedGisle Vanem
Bug: http://curl.haxx.se/mail/lib-2014-11/0035.html Reported-by: Jan Ehrhardt
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)
2014-10-06ssh_statemach_act: split out assignment from checkDaniel Stenberg
just a minor code style thing to make the code clearer
2014-10-03ssh: comment "fallthrough" in switch statementDaniel Stenberg
2014-10-03ssh: improve key file searchJeremy Lin
For private keys, use the first match from: user-specified key file (if provided), ~/.ssh/id_rsa, ~/.ssh/id_dsa, ./id_rsa, ./id_dsa Note that the previous code only looked for id_dsa files. id_rsa is now generally preferred, as it supports larger key sizes. For public keys, use the user-specified key file, if provided. Otherwise, try to extract the public key from the private key file. This means that passing --pubkey is typically no longer required, and makes the key-handling behavior more like OpenSSH.
2014-09-07Ensure progress.size_dl/progress.size_ul are always >= 0Brandon Casey
Historically the default "unknown" value for progress.size_dl and progress.size_ul has been zero, since these values are initialized implicitly by the calloc that allocates the curl handle that these variables are a part of. Users of curl that install progress callbacks may expect these values to always be >= 0. Currently it is possible for progress.size_dl and progress.size_ul to by set to a value of -1, if Curl_pgrsSetDownloadSize() or Curl_pgrsSetUploadSize() are passed a "size" of -1 (which a few places currently do, and a following patch will add more). So lets update Curl_pgrsSetDownloadSize() and Curl_pgrsSetUploadSize() so they make sure that these variables always contain a value that is >= 0. Updates test579 and test599.

2014-05-22bits.close: introduce connection close trackingDaniel Stenberg
Make all code use connclose() and connkeep() when changing the "close state" for a connection. These two macros take a string argument with an explanation, and debug builds of curl will include that in the debug output. Helps tracking connection re-use/close issues.
2014-04-26INFILESIZE: fields in UserDefined must not be changed run-timeDaniel Stenberg
set.infilesize in this case was modified in several places, which could lead to repeated requests using the same handle to get unintendent/wrong consequences based on what the previous request did!
2014-03-15ssh: prevent a logic error that could result in an infinite loopDan Fandrich
2014-03-14ssh: removed a redundant close state transitionDan Fandrich

2014-03-06ssh: Pass errors from libssh2_sftp_read up the stackDan Fandrich
2014-02-19SFTP: skip reading the dir when NOBODY=1Daniel Stenberg
When asking for an SFTP directory with NOBODY set, no directory contents should be retrieved. Bug: http://curl.haxx.se/mail/lib-2014-02/0155.html
2014-02-06ssh: Fixed a NULL pointer dereference on OOM conditionDan Fandrich
2014-01-20SFTP: stat remote file also when CURLOPT_NOBODY is 1Fabian Frank
Make it possible to call curl_easy_getinfo(curl, CURLINFO_CONTENT_LENGTH_DOWNLOAD, &filesize) and related functions on remote sftp:// files, without downloading them. Reported-by: Yingwei Liu Bug: http://curl.haxx.se/mail/lib-2014-01/0139.html
2013-12-31mprintf: Replaced internal usage of FORMAT_OFF_T and FORMAT_OFF_TUSteve Holme
Following commit 0aafd77fa4c6f2, replaced the internal usage of FORMAT_OFF_T and FORMAT_OFF_TU with the external versions that we expect API programmers to use. This negates the need for separate definitions which were subtly different under different platforms/compilers.
2013-12-20vtls: renamed sslgen.[ch] to vtls.[ch]Daniel Stenberg
2013-12-20vtls: created subdir, moved sslgen.[ch] there, updated all include linesDaniel Stenberg
2013-10-21ssh: initialize per-handle data in ssh_connect()Kamil Dudka
... if not already initialized. This fixes a regression introduced by commit 4ad8e142da463ab208d5b5565e53291c8e5ef038, which caused test619 to intermittently fail on certain machines (namely Fedora build hosts).
2013-10-15ssh: Handle successful SSH_USERAUTH_NONETyler Hall
According to the documentation for libssh2_userauth_list(), a NULL return value is not necessarily an error. You must call libssh2_userauth_authenticated() to determine if the SSH_USERAUTH_NONE request was successful. This fixes a segv when using sftp on a server that allows logins with an empty password. When NULL was interpreted as an error, it would free the session but not flag an error since the libssh2 errno would be clear. This resulted in dereferencing a NULL session pointer.

2013-10-12ssh: improve the logic for detecting blocking directionKamil Dudka
This fixes a regression introduced by commit 0feeab78 limiting the speed of SCP upload to 16384 B/s on a fast connection (such as localhost).
2013-08-12SessionHandle: the protocol specific pointer is now a void *Daniel Stenberg
All protocol handler structs are now opaque (void *) in the SessionHandle struct and moved in the request-specific sub-struct 'SingleRequest'. The intension is to keep the protocol specific knowledge in their own dedicated source files [protocol].c etc. There's some "leakage" where this policy is violated, to be addressed at a later point in time.
