2021-09-09feh_http_load_image: Use mkstemps to save image with correct suffixDaniel Friesel-4/+25
This allows feh to load .gif images via libcurl, as some imlib2 versions only load gif images if the suffix is correct. It's also more convenient when using --keep-http. To achieve this, feh needs to use mkstemps. mkstemps is a non-standard extension that is available on several systems. Compile feh with "mkstemps=0" to use mkstemp instead. Closes #630
2021-07-23Fix memory leak on error pathTobias Stoeckmann-1/+1
The snprintf string argument should not be duplicated. It is not needed and also not released afterwards.
2021-07-23feh_draw_exif: Fix out of bounds array access when handling long linesDaniel Friesel-4/+3
2021-07-23Fix out of boundary access with exif (#617)Tobias Stoeckmann-15/+15
* Fix out of boundary access The while-loop is not finished when pos is set to EXIF_MAX_DATA. Instead, the loop continues and therefore tries to access data outside of the array. This is triggered when compiled with exif=1 and asan: $ feh --draw-exif image.jpg * Fixed formatting No functional change but makes previous commit easier verifiable (independent of tab space setup). * Call break; instead of setting pos2 to a magic value This is in line with the following else clause * Another cosmetic adjustment Co-authored-by: Daniel Friesel <derf@finalrewind.org>

2021-06-09Add JPEG XL to supported file formatsAlistair-0/+5
Note that Imlib2 does not support JXL images out of the box. However, the imlib2-jxl loader (https://github.com/alistair7/imlib2-jxl) does.

2020-12-05free accompanying EXIF data when freeing an imageDaniel Friesel-0/+7
This fixes two memory bugs that only manifest with exif=1 and long-running slideshows. * when feh loads an image, it writes exif data to file->ed. Previously, this data was never free'd, causing a memory leak on subsequent loads of the same file. * As file->ed is never free'd, the accumulated EXIF data consumes a significant amount of memory over time. with slideshow-delay = 10 and two days of runtime, feh may exceed 1 GB of memory usage. If the slideshow is so large that feh does not encounter the same image twice in this time, this is not detected as a memory leak, as each EXIF data chunk is referenced from the filelist. See <https://github.com/derf/feh/issues/553> for details. Closes #553
2020-11-30Check magic bytes before passing a file to Imlib2's loaderDaniel Friesel-3/+100
This works around a regression in Imlib2, which makes (un)loadable file detection quite slow when handling e.g. large video files. See <https://phab.enlightenment.org/T8739> and <https://github.com/derf/feh/issues/505> for details. Closes #505

2020-04-08fix a memory leak when loading a non-native image more than onceDaniel Friesel-0/+12
feh_file_info_load is called even if file_info is already populated, so the original file_info struct is never freed. This results in a leak of ~44 Byte for each subsequenc image load

2020-03-26Quit curl cleanly even if libcurl is old.c99pedant-0/+6
Building feh 3.3 on CentOS 7 x86_64 warns `curl_quit_function` in `imlib.c` is unused: ``` cc -g -O2 -Wall -Wextra -pedantic -std=c11 -D_POSIX_C_SOURCE=200809L -D_XOPEN_SOURCE=700 -DHAVE_LIBCURL -DHAVE_VERSCMP -DHAVE_LIBXINERAMA -DHAVE_LIBEXIF -DPREFIX=\"/usr/local\" -DPACKAGE=\"feh\" -DVERSION=\"3.3\" -c -o imlib.o imlib.c imlib.c:545:12: warning: ‘curl_quit_function’ defined but not used [-Wunused-function] static int curl_quit_function(void *clientp, curl_off_t dltotal, curl_off_t dlnow, curl_off_t ultotal, curl_off_t ulnow) ^ ``` The `curl_quit_function` code was added in response to pull [#435](https://github.com/derf/feh/pull/435) In issue [#485](https://github.com/derf/feh/issues/485) a fellow CentOS 7 user had an error building feh because CentOS 7 is locked into an old version of libcurl. In the fix, a version guard was wrapped around the `curl_easy_setopt` call, but the rest of the code was unchanged. Since I don't want to maintain a local build of libcurl, I looked at the curl docs and noticed there is an older callback which serves the same purpose: https://curl.haxx.se/libcurl/c/CURLOPT_PROGRESSFUNCTION.html The difference between `PROGRESS` and `XFERINFO` is the callback's argument types, with `PROGRESS` using `double` and `XFERINFO` using `curl_off_t`: https://curl.haxx.se/libcurl/c/CURLOPT_XFERINFOFUNCTION.html The callback's return value logic and use of `CURLOPT_NOPROGRESS` is the same. For context, the latest libcurl RPM I'm getting from yum updates is `libcurl-7.29.0-54.el7_7.2.x86_64`. The "stable" versions of other distros may encounter similar issues. The CentOS 7 "End of Life" date is 2024-06-30 so you should hear the end of this by then, at least from us pesky CentOS users.

2017-09-26Fix dead codeNiclas Zeising-3/+4
The check if buffer == NULL is always false, since buffer is an autoamtic variable allocated when entering the function. What we instead want to do is to check if the string is empty after the call to exif_get_info(), since that means we could not read any exif information. When the code once more is enabled, I discovered that we need to copy the information string into info_buf as well as into buffer, since it is the former that is used to print the exif information on top of the picture. Without this change, imlib warns about trying to write NULL strings.
