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
Needs further testing

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>

2021-06-09Add JPEG XL to supported file formatsAlistair-0/+5

2020-12-05Fix memory leak in feh_draw_exifDaniel Friesel-0/+1
2020-12-05free accompanying EXIF data when freeing an imageDaniel Friesel-1/+21
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
2020-11-30menu: Set flip/rotate menu title based on --editDaniel Friesel-1/+6

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

2020-08-28Fix segfault when closing a window in multi-window reload modeDaniel Friesel-2/+37
Issue: * start feh --multiwindow --reload 5 * close a window with "x" * wait up to 5 seconds * segfault The issue was caused by the closed window's reload timer still being active even after the winwidget was free'd.
