2018-07-12content_encoding: accept up to 4 unknown trailer bytes after raw deflate dataPatrick Monnerat
Some servers issue raw deflate data that may be followed by an undocumented trailer. This commit makes curl tolerate such a trailer of up to 4 bytes before considering the data is in error. Reported-by: clbr on github Fixes #2719
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
2018-05-25content_encoding: handle zlib versions too old for Z_BLOCKAlejandro R. SedeƱo
Fallback on Z_SYNC_FLUSH when Z_BLOCK is not available. Fixes #2606 Closes #2608
2018-04-15all: Refactor malloc+memset to use callocDaniel Gustafsson
When a zeroed out allocation is required, use calloc() rather than malloc() followed by an explicit memset(). The result will be the same, but using calloc() everywhere increases consistency in the codebase and avoids the risk of subtle bugs when code is injected between malloc and memset by accident. Closes https://github.com/curl/curl/pull/2497
2018-02-09content_encoding: Add "none" alias to "identity"Mohammad AlSaleh
Some servers return a "content-encoding" header with a non-standard "none" value. Add "none" as an alias to "identity" as a work-around, to avoid unrecognised content encoding type errors. Signed-off-by: Mohammad AlSaleh <CE.Mohammad.AlSaleh@gmail.com> Closes https://github.com/curl/curl/pull/2298
2017-12-27brotli: data at the end of content can be lostMikalai Ananenka
Decoding loop implementation did not concern the case when all received data is consumed by Brotli decoder and the size of decoded data internally hold by Brotli decoder is greater than CURL_MAX_WRITE_SIZE. For content with unencoded length greater than CURL_MAX_WRITE_SIZE this can result in the loss of data at the end of content. Closes #2194
2017-12-20content_encoding: rework zlib_inflatePatrick Monnerat
- When zlib version is < 1.2.0.4, process gzip trailer before considering extra data as an error. - Inflate with Z_BLOCK instead of Z_SYNC_FLUSH to maximize correct data and minimize corrupt data output. - Do not try to restart deflate decompression in raw mode if output has started or if the leading data is not available anymore. - New test 232 checks inflating raw-deflated content. Closes #2068
2017-12-20brotli: allow compiling with version 0.6.0.Patrick Monnerat
Some error codes were not yet defined in brotli 0.6.0: do not issue code for them in this case.
2017-11-13zlib/brotli: only include header files in modules needing themPatrick Monnerat
There is a conflict on symbol 'free_func' between openssl/crypto.h and zlib.h on AIX. This is an attempt to resolve it. Bug: https://curl.haxx.se/mail/lib-2017-11/0032.html Reported-By: Michael Felt
2017-11-09content_encoding: fix inflate_stream for no bytes availableJay Satiro
- Don't call zlib's inflate() when avail_in stream bytes is 0. This is a follow up to the parent commit 19e66e5. Prior to that change libcurl's inflate_stream could call zlib's inflate even when no bytes were available, causing inflate to return Z_BUF_ERROR, and then inflate_stream would treat that as a hard error and return CURLE_BAD_CONTENT_ENCODING. According to the zlib FAQ, Z_BUF_ERROR is not fatal. This bug would happen randomly since packet sizes are arbitrary. A test of 10,000 transfers had 55 fail (ie 0.55%). Ref: https://zlib.net/zlib_faq.html#faq05 Closes https://github.com/curl/curl/pull/2060
2017-11-07content_encoding: do not write 0 length dataPatrick Monnerat
2017-11-05HTTP: implement Brotli content encodingPatrick Monnerat
This uses the brotli external library (https://github.com/google/brotli). Brotli becomes a feature: additional curl_version_info() bit and structure fields are provided for it and CURLVERSION_NOW bumped. Tests 314 and 315 check Brotli content unencoding with correct and erroneous data. Some tests are updated to accomodate with the now configuration dependent parameters of the Accept-Encoding header.
2017-11-05HTTP: support multiple Content-EncodingsPatrick Monnerat
This is implemented as an output streaming stack of unencoders, the last calling the client write procedure. New test 230 checks this feature. Bug: https://github.com/curl/curl/pull/2002 Reported-By: Daniel Bankhead

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.

2011-08-21zlib: ensure user provided memory functions are used by zlib, when givenYang Tse
As a bonus, this lets our MemoryTracking subsystem track zlib operations. And also fixes a shortcut some zlib 1.2.x versions took using malloc() instead of calloc(), which would trigger memory debuggers warnings on memory being used without having been initialized.

2010-02-09- When downloading compressed content over HTTP and the app as asked libcurlDaniel Stenberg
to automatically uncompress it with the CURLOPT_ENCODING option, libcurl could wrongly provide the callback with more data than what the maximum documented amount. An application could thus get tricked into badness if the maximum limit was trusted to be enforced by libcurl itself (as it is documented). This is further detailed and explained in the libcurl security advisory 20100209 at http://curl.haxx.se/docs/adv_20100209.html

2007-11-24struct HandleData is now called struct SingleRequest, and is only for data thatDaniel Stenberg
is inited at the start of the DO action. I removed the Curl_transfer_keeper struct completely, and I had to move out a few struct members (that had to be set before DO or used after DONE) to the UrlState struct. The SingleRequest struct is accessed with SessionHandle->req. One of the biggest reasons for doing this was the bunch of duplicate struct members in HandleData and Curl_transfer_keeper since it was really messy to keep track of two variables with the same name and basically the same purpose!
