2018-08-21curl-compilers: enable -Wimplicit-fallthrough=4 for GCCMarcel Raad
This enables level 4 instead of the default level 3, which of the currently used comments only allows /* FALLTHROUGH */ to silence the warning. Closes https://github.com/curl/curl/pull/2747
2018-08-11Silence GCC 8 cast-function-type warningsMarcel Raad
On Windows, casting between unrelated function types is fine and sometimes even necessary, so just use an intermediate cast to (void (*) (void)) to silence the warning as described in [0]. [0] https://gcc.gnu.org/onlinedocs/gcc-8.1.0/gcc/Warning-Options.html Closes https://github.com/curl/curl/pull/2860
2018-08-09formdata: Remove unused macro HTTPPOST_CONTENTTYPE_DEFAULTRikard Falkeborn
Its usage was removed in 84ad1fd3047815f9c6e78728bb351b828eac10b1. Closes #2852
2018-06-11cppcheck: fix warningsMarian Klymov
- Get rid of variable that was generating false positive warning (unitialized) - Fix issues in tests - Reduce scope of several variables all over etc Closes #2631
2018-05-21checksrc: make sure sizeof() is used *with* parenthesesDaniel Stenberg
... and unify the source code to adhere. Closes #2563
2018-02-05formdata: use the mime-content type functionDaniel Stenberg
Reduce code duplication by making Curl_mime_contenttype available and used by the formdata function. This also makes the formdata function recognize a set of more file extensions by default. PR #2280 brought this to my attention. Closes #2282
2017-10-12mime: keep "text/plain" content type if user-specified.Patrick Monnerat
Include test cases in 554, 587, 650. Fixes https://github.com/curl/curl/issues/1986
2017-09-22form/mime: field names are not allowed to contain zero-valued bytes.Patrick Monnerat
Also suppress length argument of curl_mime_name() (names are always zero-terminated).
2017-09-11code style: use spaces around plusesDaniel Stenberg
2017-09-11code style: use spaces around equals signsDaniel Stenberg
2017-09-06mime: drop internal FILE * support.Patrick Monnerat
- The part kind MIMEKIND_FILE and associated code are suppressed. - Seek data origin offset not used anymore: suppressed. - MIMEKIND_NAMEDFILE renamed MIMEKIND_FILE; associated fields/functions renamed accordingly. - Curl_getformdata() processes stdin via a callback.
2017-09-05mime: unified to use the typedef'd mime structs everywhereDaniel Stenberg
... and slightly edited to follow our code style better.
2017-09-03mime: remove support "-" stdin pseudo-file name in curl_mime_filedata().Patrick Monnerat
This feature is badly supported in Windows: as a replacement, a caller has to use curl_mime_data_cb() with fread, fseek and possibly fclose callbacks to process opened files. The cli tool and documentation are updated accordingly. The feature is however kept internally for form API compatibility, with the known caveats it always had. As a side effect, stdin size is not determined by the cli tool even if possible and this results in a chunked transfer encoding. Test 173 is updated accordingly.
2017-09-02mime: new MIME API.Patrick Monnerat
Available in HTTP, SMTP and IMAP. Deprecates the FORM API. See CURLOPT_MIMEPOST. Lib code and associated documentation.
2017-05-11formdata: fix -Wcomma warningMarcel Raad
clang 5.0 complains: possible misuse of comma operator here [-Wcomma] Change the comma to a semicolon to fix that.
2017-05-09formboundary: convert assert into run-time checkDaniel Stenberg
... to really make sure the boundary fits in the target buffer. Fixes unused parameter 'buflen' warning. Reported-by: Michael Kaufmann Bug: https://github.com/curl/curl/pull/1468#issuecomment-300078754
2017-05-08rand: treat fake entropy the same regardless of endiannessJay Satiro
When the random seed is purposely made predictable for testing purposes by using the CURL_ENTROPY environment variable, process that data in an endian agnostic way so the the initial random seed is the same regardless of endianness. - Change Curl_rand to write to a char array instead of int array. - Add Curl_rand_hex to write random hex characters to a buffer. Fixes #1315 Closes #1468 Co-authored-by: Daniel Stenberg Reported-by: Michael Kaufmann
2017-04-26lib: remove unused codeMarcel Raad
This fixes the following clang warnings: macro is not used [-Wunused-macros] will never be executed [-Wunreachable-code] Closes https://github.com/curl/curl/pull/1448
2017-03-13Improve code readbilitySylvestre Ledru
... by removing the else branch after a return, break or continue. Closes #1310
2017-03-03build: fix gcc7 implicit fallthrough warningsAlexis La Goutte
Mark intended fallthroughs with /* FALLTHROUGH */ so that gcc will know it's expected and won't warn on [-Wimplicit-fallthrough=]. Closes https://github.com/curl/curl/pull/1297
2017-02-23formdata: check for EOF when reading from stdinDaniel Stenberg
Reported-by: shachaf@users.noreply.github.com Fixes #1281
2016-12-25formdata: use NULL, not 0, when returning pointersDaniel Stenberg
2016-12-14checksrc: warn for assignments within if() expressionsDaniel Stenberg
... they're already frowned upon in our source code style guide, this now enforces the rule harder.
2016-12-13checksrc: stricter no-space-before-paren enforcementDaniel Stenberg
In order to make the code style more uniform everywhere
2016-11-24checksrc: move open braces to comply with function declaration styleDaniel Stenberg
2016-11-24checksrc: code style: use 'char *name' styleDaniel Stenberg
2016-11-14Curl_rand: fixed and moved to rand.cDaniel Stenberg
Now Curl_rand() is made to fail if it cannot get the necessary random level. Changed the proto of Curl_rand() slightly to provide a number of ints at once. Moved out from vtls, since it isn't a TLS function and vtls provides Curl_ssl_random() for this to use. Discussion: https://curl.haxx.se/mail/lib-2016-11/0119.html
2016-10-31strcasecompare: is the new name for strequal()Daniel Stenberg
... to make it less likely that we forget that the function actually does case insentive compares. Also replaced several invokes of the function with a plain strcmp when case sensitivity is not an issue (like comparing with "-").
2016-10-08formpost: avoid silent snprintf() truncationDaniel Stenberg
The previous use of snprintf() could make libcurl silently truncate some input data and not report that back on overly large input, which could make data get sent over the network in a bad format. Example: $ curl --form 'a=b' -H "Content-Type: $(perl -e 'print "A"x4100')"
2016-10-04formpost: trying to attach a directory no longer crashesDaniel Stenberg
The error path would previously add a freed entry to the linked list. Reported-by: Toby Peterson Fixes #1053
2016-06-22internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg
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

2016-04-03formdata: use appropriate fopen() macrosDaniel Stenberg
2016-03-18formdata.c: Fixed compilation warningSteve Holme
formdata.c:390: warning: cast from pointer to integer of different size Introduced in commit ca5f9341ef this happens because a char*, which is 32-bits wide in 32-bit land, is being cast to a curl_off_t which is 64-bits wide where 64-bit integers are supported by the compiler. This doesn't happen in 64-bit land as a pointer is the same size as a curl_off_t. This fix doesn't address the fact that a 64-bit value cannot be used for CURLFORM_CONTENTLEN when set in a form array and compiled on a 32-bit platforms, it does at least suppress the compilation warning.
2016-02-29formpost: fix memory leaks in AddFormData error branchesDaniel Stenberg
Reported-by: Dmitry-Me Fixes #688
2016-02-03URLs: change all http:// URLs to https://Daniel Stenberg
2015-12-07formdata: Check if length is too large for memoryJay Satiro
- If the size of the length type (curl_off_t) is greater than the size of the size_t type then check before allocating memory to make sure the value of length will fit in a size_t without overflow. If it doesn't then return CURLE_BAD_FUNCTION_ARGUMENT. Bug: https://github.com/bagder/curl/issues/425#issuecomment-154518679 Reported-by: Steve Holme
2015-11-02formadd: support >2GB files on windowsDaniel Stenberg
Closes #425
2015-10-31curl.h: s/HTTPPOST_/CURL_HTTPOST_Daniel Stenberg
Fixes a name space pollution at the cost of programs using one of these defines will no longer compile. However, the vast majority of libcurl programs that do multipart formposts use curl_formadd() to build this list. Closes #506
2015-09-26build: fix failures with -Wcast-align and -WerrorTatsuhiro Tsujikawa
Closes #457
2015-06-02checksrc: detect fopen() for text without the FOPEN_* macrosDaniel Stenberg
Follow-up to e8423f9ce150 with discussionis in https://github.com/bagder/curl/pull/258 This check scans for fopen() with a mode string without 'b' present, as it may indicate that an FOPEN_* define should rather be used.
2015-03-24curl_memory: make curl_memory.h the second-last header file loadedDan Fandrich
This header file must be included after all header files except memdebug.h, as it does similar memory function redefinitions and can be similarly affected by conflicting definitions in system or dependent library headers.
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.
2015-03-16Bug #149: Deletion of unnecessary checks before a few calls of cURL functionsMarkus Elfring
The following functions return immediately if a null pointer was passed. * Curl_cookie_cleanup * curl_formfree It is therefore not needed that a function caller repeats a corresponding check. This issue was fixed by using the software Coccinelle 1.0.0-rc24. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net>
2015-03-16Bug #149: Deletion of unnecessary checks before calls of the function "free"Markus Elfring
The function "free" is documented in the way that no action shall occur for a passed null pointer. It is therefore not needed that a function caller repeats a corresponding check. http://stackoverflow.com/questions/18775608/free-a-null-pointer-anyway-or-check-first This issue was fixed by using the software Coccinelle 1.0.0-rc24. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net>
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.
2014-11-05curl_easy_duphandle: CURLOPT_COPYPOSTFIELDS read out of boundsDaniel Stenberg
When duplicating a handle, the data to post was duplicated using strdup() when it could be binary and contain zeroes and it was not even zero terminated! This caused read out of bounds crashes/segfaults. Since the lib/strdup.c file no longer is easily shared with the curl tool with this change, it now uses its own version instead. Bug: http://curl.haxx.se/docs/adv_20141105.html CVE: CVE-2014-3707 Reported-By: Symeon Paraschoudis
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)
2014-10-08FormAdd: precaution against memdup() of NULL pointerDaniel Stenberg
Coverity CID 252518. This function is in general far too complicated for its own good and really should be broken down into several smaller funcitons instead - but I'm adding this protection here now since it seems there's a risk the code flow can end up here and dereference a NULL pointer.
