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.
2022-01-16remove local getopt_long() implementationGuilherme Janczak-1256/+1
getopt_long() is widely supported these days, removing it from the source tree should be okay. Here's documentation or the implementation of getopt_long on many systems: All the BSDs: https://man.netbsd.org/NetBSD-9.2-STABLE/getopt_long.3 https://man.openbsd.org/OpenBSD-7.0/getopt_long https://www.freebsd.org/cgi/man.cgi?query=getopt_long https://leaf.dragonflybsd.org/cgi/web-man?command=getopt_long Illumos (OpenSolaris fork): https://illumos.org/man/3c/getopt_long The musl, newlib, and uclibc-ng libcs: https://gogs.waldemar-brodkorb.de/oss/uclibc-ng/src/master/libc/unistd/getopt_long-simple.c#L49-L52 https://git.musl-libc.org/cgit/musl/tree/src/misc/getopt_long.c#n140 https://sourceware.org/git/?p=newlib-cygwin.git;a=blob;f=newlib/libc/stdlib/getopt.c;h=d4f225a7a735dc741d2874eb6c131b6fce2967c5;hb=HEAD#l475 Mingw-w64: https://github.com/mirror/mingw-w64/blob/master/mingw-w64-crt/misc/getopt.c#L542-L549 Mac OS X: https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/getopt_long.3.html

2021-12-24Disable --auto-rotate in feh builds compiled wiht Imlib2 1.7.5+Daniel Friesel-1/+7
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

2021-09-21Fix crash when X11 is connected via FD 0.Daniel Friesel-3/+9
If stdin is not connected, the X11 connection may use FD 0, which is traditionally used for STDIN. Do not attempt reads from fd 0 unless it _really_ is connected to a terminal on stdin. Reported by https://github.com/pvanstam, thanks a lot! Closes #631 Closes #632
2021-09-21Do not hardcode STDIN_FILENO == 0Daniel Friesel-2/+2
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
2021-07-25Set correct window size when applying --zoom outside of -. / -FDaniel Friesel-3/+18

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.
2021-07-23Fix out of boundary access on illegal argumentTobias Stoeckmann-1/+1
Calling feh with an empty argument leads to out of boundary access. This can be seen best when compiled with asan: $ feh ""
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>
