Subject: [PATCH 1/2] unzip: reduce file name size to 65535 to work with
|
|
external minizip
|
|
MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

The external minizip project has changed the unzGetCurrentFileInfo()
|
|
function to take a uint16_t as the filename size, instead of a uLong
|
|
as in the original version in zlib.
|
|
|
|
(Reported as https://github.com/nmoinvaz/minizip/issues/490 but it
|
|
was 3½ years ago and might be too late to fix it now, although changing
|
|
it back to a *larger* type is a lot safer than reducing the size, and
|
|
perhaps they should.)
|
|
|
|
This means that our 65536-byte buffer gets truncated to zero, as the
|
|
compiler tells us when we build agaisnt the external minizip:
|
|
|
|
domoticz/main/unzip_stream.h:140:50: warning: conversion from ‘long unsigned int’ to ‘uint16_t’ {aka ‘short unsigned int’} changes value from ‘65536’ to ‘0’ [-Woverflow]
|
|
140 | unzGetCurrentFileInfo(handler_, &info, path, sizeof(path), NULL, 0, NULL, 0);
|
|
| ^~~~~~~~~~~~
|
|
|
|
Reduce the buffer size to 65535 bytes instead.
