Michael Haggerty	99397152a3	register_tempfile(): new function to handle an existing temporary file Allow an existing file to be registered with the tempfile-handling infrastructure; in particular, arrange for it to be deleted on program exit. This can be used if the temporary file has to be created in a more complicated way than just open(). For example: * If the file itself needs to be created via the lockfile API * If it is not a regular file (e.g., a socket) Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>	10 years ago
Michael Haggerty	354ab11206	tempfile: add several functions for creating temporary files Add several functions for creating temporary files with automatically-generated names, analogous to mkstemps(), but also arranging for the files to be deleted on program exit. The functions are named according to a pattern depending how they operate. They will be used to replace many places in the code where temporary files are created and cleaned up ad-hoc.

Michael Haggerty	7eba6ce5c7	prepare_tempfile_object(): new function, extracted from create_tempfile() This makes the next step easier. The old code used to use "path" to set the initial length of tempfile->filename. This was not helpful because path was usually relative whereas the value stored to filename will be absolute. So just initialize the length to 0. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>	10 years ago
Michael Haggerty	1a9d15db25	tempfile: a new module for handling temporary files A lot of work went into defining the state diagram for lockfiles and ensuring correct, race-resistant cleanup in all circumstances. Most of that infrastructure can be applied directly to any temporary file. So extract a new "tempfile" module from the "lockfile" module. Reimplement lockfile on top of tempfile. Subsequent commits will add more users of the new module. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>	10 years ago
