Subject: With mhstore -clobber auto/suffix, when looking for a new filename,
X-Git-Url: http://git.marmaro.de/?a=commitdiff_plain;ds=sidebyside;h=2b7b705f7d986903b6e2190b559e7211e8e79f49;hp=2b7b705f7d986903b6e2190b559e7211e8e79f49;p=mmh

With mhstore -clobber auto/suffix, when looking for a new filename,
actually open(2) the file with O_CREAT | O_EXCL to avoid the race
condition when figuring out the filename first and opening it later.
