2022-02-08global initialization for libmagicChristian Hesse-40/+54
Add a global `magic_t magic` and initialize it just once. Also `feh_is_image()` now calls itself to check compressed files, saving some duplicate code.
2022-02-08use libmagic to detect valid file formatsChristian Hesse-83/+51
Writing our own magic bytes detection is prone to errors and an everlasting catch-up-game. Let's use libmagic to get things right, this is less code and makes things more reliable. Building without libmagic is still possible. That will make the code act like specifying FEH_SKIP_MAGIC=1, effectively passing everything to imlib2.

2021-12-24Disable --auto-rotate in feh builds compiled wiht Imlib2 1.7.5+Daniel Friesel-1/+2
Imlib2 v1.7.5 introduces automatic (and transparent) orientation adjustment based on EXIF orientation tags. This makes feh's --auto-rotate function both superfluous and erroneous: It doesn't know about Imlib2's adjustments, so it rotates an image which is already correctly oriented, leading to incorrect orientation. I am not aware of a simple run-time check for detecting whethen running Imlib2 < 1.7.5 or ≥ 1.7.5. For now, feh disables --auto-rotate entirely when compiled on a system with Imlib2 1.7.5+ and outputs a warning when the option is used. Rationale: The Imlib2 version available at run-time should in most cases be at least as recent as the Imlib2 version used at compile-time. So, while there may be cases where feh was compiled with Imlib2 1.7.4 and exhibits erroneous auto-rotate behaviour on an Imlib2 1.7.5 system, the inverse case (a feh with disabled auto-rotate support running on Imlib2 1.7.4) should be sufficiently rare. If it does occur, it can be remedied by compiling feh from source locally. Possible caveat: Imlib2 only adjusts for EXIF orientation when loading JPEG and TIFF images. If there are additional EXIF-aware file formats supported by feh, but not Imlib2, they lose auto-rotate support. Reference: GitHub issue #642
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 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>

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.
