2021-03-04Experiment with scanning using openat() rather than chdir()openatYorhel6-173/+87
A slightly different approach. In terms of syscalls it probably doesn't matter at all, but it's a simpler, less hacky and maybe more efficient way to work around PATH_MAX limitations than constantly chdir()'ing for each directory. Should also fix the chdir("..") fail case in MacOS firmlink scenarios, though I haven't a clue if MacOS implements all these openat()-related calls in the first place. Downsides: - Less portable. Everything is in POSIX, but it's more recent than what we used to use. - Requires more open file descriptions, might hit the limit for deeply nested directories. Haven't done much testing yet, but there's a bunch of TODO's: - Make refreshing work again (not sure what's going wrong there) - See if we can report readdir() etc errors again? - Make firmlink detection work again? - See how portable this really is. - Also update file deletion code

2020-05-15dir_scan.c: Call statfs() with relative pathYorhel1-1/+1
So we get around the PATH_MAX limitation. Also a tiny bit more efficient, I hope.

2020-05-06Fix calculating of directory apparent sizes with hard linksYorhel1-1/+1
Silly one-character typo that causes directory apparent sizes to be very off in some scenarios. Reported & patched by Andrew Neitsch.

2020-02-06Fix khash.h -> khashl.h reference in MakefileYorhel1-2/+2
2020-02-04deps/khash.h -> khashl.h for slightly reduced memory usageYorhel3-624/+357
Reduces memory by a tiny bit. Arguably we never needed tombstones because entries are never removed, so there shouldn't be any performance hit there. We don't even need a 'used' flag either, considering that can be represented by a NULL value, but I'm not really up for implementing/modifying my own hash table. ref: https://attractivechaos.wordpress.com/2019/12/28/deletion-from-hash-tables-without-tombstones/
2020-01-25Fix definitions of global vars `confirm_quit` and `dir_process`Yorhel4-2/+3
They were defined (rather than just declared) in .h files, when they really should be defined in at most a single .c file. Fixes #140.
2019-12-15static: Add AArch64 binariesYorhel1-0/+1
2019-11-14Fix cross compiler targetsYorhel1-4/+4
I assumed that ./configure would fail if it can't find a suitable compiler for the given --host, but it just falls back to the host gcc. Fixes #138

2019-07-23Handle malloc failure by pausing any activityYorhel12-37/+68
This is a best-effort approach to save ncdu state when memory is low. There's likely allocation in libraries that isn't being checked (ncurses, printf). Fixes #132 (it actually doesn't, that needs a 64bit static binary too, but I'll get to that)
2019-04-19Clear errno before getch()Yorhel1-0/+1
Fixes #128.
2019-02-19dir_scan: Avoid allocating new copies of buf_dirMartin Storsjö1-1/+2
This allocation is currently leaked, but as long as we don't allocate new ones for each refresh, that shouldn't be much of an issue. (cherry picked from commit 9dc2d32a8fb557112f8f96cd14d50b934543ce39)

2019-01-24symlinks: Only call stat_to_dir() once, impove manualYorhel2-12/+12
stat_to_dir() assumes that buf_dir is clean; calling it twice breaks that asumption.
2019-01-24Add a '--follow-symlinks' optionSimon Doppler4-0/+17
Symlink loops are handled by the stat(2) syscall. Symlinks pointing to a directory are ignored (to avoid loops in the recursive scan).
2019-01-21Fix minor typoYorhel1-1/+1
2019-01-21add a max modified time, or mtime, view and sortingAlex Wilson8-10/+84
This adds an 'm' command to show the latest modified time of all files in a directory. The 'M' command allows for ascending and descending mtime sorting. These are only enabled with the -e flag and overload the dir_ext mtime field.
2019-01-20Fix crash when attempting to sort an empty directoryYorhel1-1/+2
I had taken care to not sort empty directories during dirlist_open(), but forgot that manual user actions can still cause dirlist_set_sort() to be called, which does not handle empty directories. Reported by Alex Wilson.
