* Add verbose flag to pngoJune McEnroe2018-03-02
| | | | I don't like verbose flags but I want to see what pngo manages to do.
* Use memmove in pngo where neededJune McEnroe2018-02-28
|
* Clean up pngoJune McEnroe2018-02-28
| | | | | | Big difference is changing lines from an array of structs containing pointers into data to an array of pointers to structs pointing directly into data.
* Abort on other values of enums in pngoJune McEnroe2018-02-22
|
* Fix zlib types on 32-bitJune McEnroe2018-02-22
|
* Add unistd.h include to pngo.cJune McEnroe2018-02-20
| | | | Where getopt properly lives.
* Take multiple inputs to pngoJune McEnroe2018-02-20
|
* Reduce bit depth in pngoJune McEnroe2018-02-20

|
* Tweak pngo codeJune McEnroe2018-02-17
|
* Eliminate redundant alpha in pngoJune McEnroe2018-02-17
|
* Support all bit depths in pngoJune McEnroe2018-02-17
|
* Implement filter heuristic from PNG specJune McEnroe2018-02-17
|
* Fix pngo glitchJune McEnroe2018-02-16
| | | | | Basically changing the filter type without actually recalculating the bytes results in some interesting stuff.
* Refactor scanlines and filter bytes, more glitchJune McEnroe2018-02-16
|
* Fix paethPredictor comparisonJune McEnroe2018-02-16
|
* Handle more color types, depths, IDATs in pngoJune McEnroe2018-02-16
| | | | | Also fixed reconData so that it can at least round-trip the glitches it creates.
* Add WIP pngo which produces glitch artJune McEnroe2018-02-15
Since fmt() uses 8 alternating static buffers, and cache_lock might call cache_create_dirs() multiple times, which in turn might call fmt() twice, after four iterations lockfile would be overwritten by a cachedirectory path. In worst case, this could cause the cachedirectory to be unlinked and replaced by a cachefile. Fix: use xstrdup() on the result from fmt() before assigning to lockfile, and call free(lockfile) before exit.

Thanks to Linus for noticing (again).

This could happen on broken setups or under crazy server load. Incidentally, this also fixes a lurking bug in cache_lock() where an uninitialized returnvalue was used.
