Google Summer of Code and Mailutils

My recent work:

  • libmuauth: new generalized mu_tls_begin() for POP/IMAP/SMTP protocols,
  • code reorganization: added new libmu_mailer for handling sendmail and SMTP,
  • added STARTTLS support to SMTP code handling,
  • added support for new protocols: POPS (pops://) and IMAPS (imaps://),
  • fixed APOP handling.

SLOCCount (pronounced "sloc-count") is a suite of programs for counting physical source lines of code in potentially large software systems. SLOCCount will try to quickly estimate development time and effort given only the lines of code it computes, using the original Basic COCOMO model. Some of my statistics:

GNU Anubis:

Total Physical Source Lines of Code (SLOC)                = 32,581
Development Effort Estimate, Person-Years (Person-Months) = 7.76 (93.07)
 (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months)                         = 1.17 (14.00)
 (Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule)  = 6.65
Total Estimated Cost to Develop                           = $ 1,047,742
 (average salary = $56,286/year, overhead = 2.40).

GNU Mailutils:

Total Physical Source Lines of Code (SLOC)                = 138,442
Development Effort Estimate, Person-Years (Person-Months) = 35.43 (425.15)
 (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months)                         = 2.08 (24.93)
 (Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule)  = 17.05
Total Estimated Cost to Develop                           = $ 4,786,002
 (average salary = $56,286/year, overhead = 2.40).

Cheetah News Aggregator:

Total Physical Source Lines of Code (SLOC)                = 11,816
Development Effort Estimate, Person-Years (Person-Months) = 2.67 (32.09)
 (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months)                         = 0.78 (9.34)
 (Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule)  = 3.44
Total Estimated Cost to Develop                           = $ 361,190
 (average salary = $56,286/year, overhead = 2.40).
